BackgroundFew longitudinal studies have concurrently investigated cognitive appraisal, coping and psychological adjustment in patients with terminal cancer. This study aimed to (i) consider patterns of change in these variables during the last year of life and (ii) consider covariates associated with patients' psychological adjustment.Methods and patientsQuestionnaires were sent to a cohort of stage IV melanoma patients seen at the Sydney Melanoma Unit between 1991 and 1996, approximately every 3 months, for up to 2 years. A sub-sample of 110 patients completed at least one questionnaire in the last year of life. Repeated measures linear regression was used to model cognitive appraisal, coping and psychological adjustment.ResultsIn the last year of life, patients' cognitive appraisal of their disease remained relatively stable, whereas their use of active coping strategies increased (p=0. 04). There was some deterioration in psychological adjustment, particularly in patients' ability to minimize the impact of cancer on daily life (p=0.03), but this effect did not remain significant when patients' level of tiredness was included in the model. Cognitive appraisal, coping style and quality of life indicators were all associated with psychological adjustment.ConclusionThese findings suggest that while patients work hard to actively cope with their disease, they experience increasing levels of tiredness, and deterioration in their mood and ability to function in their daily lives.

OBJECTIVES: To determine whether tango dancing is as effective as mindfulness meditation in reducing symptoms of psychological stress, anxiety and depression, and in promoting well-being. DESIGN: This study employed analysis of covariance (ANCOVA) and multiple regression analysis. PARTICIPANTS: Ninety-seven people with self-declared depression were randomised into tango dance or mindfulness meditation classes, or to control/waiting-list. SETTING: classes were conducted in a venue suitable for both activities in the metropolitan area of Sydney, Australia. INTERVENTIONS: Participants completed six-week programmes (1½h/week of tango or meditation). The outcome measures were assessed at pre-test and post-test. MAIN OUTCOME MEASURES: Depression, Anxiety and Stress Scale; The Self Esteem Scale; Satisfaction with Life Scale, and Mindful Attention Awareness Scale. RESULTS: Sixty-six participants completed the program and were included in the statistical analysis. Depression levels were significantly reduced in the tango (effect size d=0.50, p=.010), and meditation groups (effect size d=0.54, p=.025), relative to waiting-list controls. Stress levels were significantly reduced only in the tango group (effect size d=0.45, p=.022). Attending tango classes was a significant predictor for the increased levels of mindfulness R(2)=.10, adjusted R(2)=.07, F (2,59)=3.42, p=.039. CONCLUSION: Mindfulness-meditation and tango dance could be effective complementary adjuncts for the treatment of depression and/or inclusion in stress management programmes. Subsequent trials are called to explore the therapeutic mechanisms involved. [ABSTRACT FROM AUTHOR]

Purpose: Slow accrual to cancer clinical trials impedes the progress of effective new cancer treatments. Poor physician-patient communication has been identified as a key contributor to low trial accrual. Question prompt lists (QPLs) have demonstrated a significant promise in facilitating communication in general, surgical, and palliative oncology settings. These simple patient interventions have not been tested in the oncology clinical trial setting. We aimed to develop a targeted QPL for clinical trials (QPL-CT).Method: Lung, breast, and prostate cancer patients who either had (trial experienced) or had not (trial naive) participated in a clinical trial were invited to join focus groups to help develop and explore the acceptability of a QPL-CT. Focus groups were audio-recorded and transcribed. A research team, including a qualitative data expert, analyzed these data to explore patients' decision-making processes and views about the utility of the QPL-CT prompt to aid in trial decision making.Results: Decision making was influenced by the outcome of patients' comparative assessment of perceived risks versus benefits of a trial, and the level of trust patients had in their doctors' recommendation about the trial. Severity of a patient's disease influenced trial decision making only for trial-naive patients.Conclusion: Although patients were likely to prefer a paternalistic decision-making style, they expressed valuation of the QPL as an aid to decision making. QPL-CT utility extended beyond the actual consultation to include roles both before and after the clinical trial discussion. [ABSTRACT FROM AUTHOR]

There is a lack of systematic examination of the relationship between different stressor features and fatigue. Thus, we examined which features of stressors (e.g. frequency, duration, severity, valence, type) were most strongly related to fatigue levels. Eighty-nine participants completed a short fatigue questionnaire and a comprehensive stress interview. High fatigue levels were found to be most strongly related to the number of acute interpersonal stressors and chronic difficulty stressors (<6 months duration) and psychological distress, but no other stressor measure. Thus, acute and chronic stressor frequency counts might be the best measures used in future studies assessing the relationship between stressors and fatigue. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To develop a workshop for training faculty to facilitate small group role play sessions for a communication skills training program and assess the impact of that workshop on the trainees' self-efficacy about facilitation skills. METHODS: A multi-specialty group of 33 attending physicians at a Comprehensive Cancer Center were trained in a Facilitating Communication Skills Training workshop in order to prepare them to facilitate small group role play with fellows and residents. The workshop curriculum was based on theory and literature on teaching communication skills. RESULTS: The workshop had a significant effect on participants' self-efficacy in facilitating communication skills training. At least 75% of participants reported feeling comfortable facilitating communication skills training small groups. CONCLUSION: This facilitation workshop was successful in providing participants with confidence to successfully facilitate small group role play sessions in communication skills training. PRACTICE IMPLICATIONS: In order to evaluate the effectiveness of communication skills training programs, it is important to have trained facilitators who adhere to a set of facilitation guidelines. Workshops on facilitation skills provide the background and practice time necessary as a first step in the training process. [ABSTRACT FROM AUTHOR]

Phosgene is a chemical widely used in the plastics industry and has been used in warfare. It produces a life-threatening pulmonary edema within hours of exposure, to which no specific antidote exists. This study aims to examine the pathophysiological changes seen with low tidal volume ventilation (protective ventilation (PV)) strategies compared to conventional ventilation (CV), in a model of phosgene-induced acute lung injury. Anesthetized pigs were instrumented and exposed to phosgene (concentration x time (Ct), 2,350 mg x min x m(-3)) and then ventilated with intermittent positive pressure ventilation (tidal volume (TV) = 10 ml x kg(-1); positive end expiratory pressure, 3 cm H2O; frequency, 20 breaths x min(-1); fractional concentration of inspired oxygen, 0.24), monitored for 6 hours after exposure, and then randomized into treatment groups: CV, PV (A) or (B) (TV, 8 or 6 ml x kg(-1); positive end expiratory pressure, 8 cm H2O; frequency, 20 or 25 breaths x min(-1); fractional concentration of inspired oxygen, 0.4). Pathophysiological parameters were measured for up to 24 hours. The results show that PV resulted in improved oxygenation, decreased shunt fraction, and mortality, with all animals surviving to 24 hours compared to only three of the CV animals. Microscopy confirmed reduced hemorrhage, neutrophilic infiltration, and intra-alveolar edema. [ABSTRACT FROM AUTHOR]

Studies do not provide a consensus opinion of the relationship between stress and relapse in relapsing–remitting multiple sclerosis (RRMS). Few studies have defined the critical features of these stressful situations, or examined the role of stress-mediating and -moderating variables. Available evidence indicates that the relationship between life stress and relapse is complex, and is likely to depend on factors such as stressor chronicity, frequency, severity and type, and individual patient characteristics such as depression, health locus of control and coping strategy use. Little is known about how these factors, individually or in combination, are related to MS disease activity. Viral infections are also likely to precipitate relapse in MS, and significant life-stress may further enhance this relationship. The nature and strength of these interrelationships have strong clinical implications. MS patients are particularly vulnerable to a deteriorating cycle of stressful life events, illness episodes and disability. Timely multidisciplinary care interventions aimed at both minimizing psychological distress and physical symptoms may halt this downward reciprocal cycle. Little is known of the pathogenesis of these putative stress-induced changes in disease activity, and almost all stressor studies suffer from some biases or limitations. [ABSTRACT FROM AUTHOR]

Clinical trials have come to be regarded as the gold standard for treatment evaluation. However, many doctors and their patients experience difficulties when discussing trials, leading to poor accrual to trials and questionable quality of informed consent. We have previously developed a typology for ethical communication about Phase II and III clinical trials within four domains: (a) shared decision making, (b) sequencing information, (c) type and clarity of information, and (d) disclosure/coercion. The aim of this study was to compare current clinical practice when seeking informed consent with this typology. Fifty-nine consultations in which 10 participating oncologists sought informed consent were audiotaped. Verbatim transcripts were analysed using a coding system to (a) identify the presence or absence of aspects of the four domains and (b) rate the quality of aspects of two domains: (i) shared decision-making and (ii) type and clarity of information. Oncologists rarely addressed aspects of shared decision-making, other than offering to delay a treatment decision (78%). Moreover, many of these discussions scored poorly with respect to ideal content. The oncologists were rarely consistent with the sequence of information provision. A general rationale for randomising was only described in 46% of consultations. In almost one third of the consultations (28.8%) doctors made implicit statements favouring one option over another, either standard or clinical trial treatment. Doctors complied with some but not other aspects of a standard procedure for discussing clinical trials. This reflects the difficulty inherent in seeking ethical informed consent and the need for communication skills training for oncologists. [ABSTRACT FROM AUTHOR]

Randomised clinical trials have come to be regarded as the gold standard in treatment evaluation. However, many doctors see the discussion of a clinical trial as an intrusion into the doctor-patient relationship and find these discussions difficult to initiate. Detailed informed consent is now a requirement of patient participation in trials; however, it is known that patients commonly fail to understand and recall the information conveyed. These difficulties for doctors and patients raise questions about the ethical integrity of the informed consent process. In this study, we have developed a set of communication strategies underpinned by ethical, linguistic and psychological theory, designed to assist doctors in this difficult task. Initially, audiotape transcripts of 26 consultations in which 10 medical oncologists invited patients to participate in clinical trials were analysed by expert ethicists, linguists, oncologists and psychologists, using rigorous qualitative methodology. A subset of seven of these was subjected to detailed linguistic analysis. A strategies document was developed to address themes which emerged from these analyses. This document was presented to relevant expert stakeholders. Their feedback was incorporated into the final document. Four themes emerged from the analysis; (a) shared decision-making, (b) the sequence of moves in the consultation, (c) the type and clarity of the information provided and (d) disclosure of controversial information and coercion. Detailed strategies were developed to assist doctors to communicate in these areas. We have developed a set of ethical strategies which may assist health professionals in this difficult area. A training package based on these strategies is currently being evaluated in a multi-centre randomised controlled trial. [ABSTRACT FROM AUTHOR]

Hepatic de novo lipogenesis (DNL) is a fundamental physiologic process that is often pathogenically elevated in metabolic disease. Treatment is limited by incomplete understanding of the metabolic pathways supplying cytosolic acetyl-CoA, the obligate precursor to DNL, including their interactions and proportional contributions. Here, we combined extensive 13 C tracing with liver-specific knockout of key mitochondrial and cytosolic proteins mediating cytosolic acetyl-CoA production. We show that the mitochondrial pyruvate carrier (MPC) and ATP-citrate lyase (ACLY) gate the major hepatic lipogenic acetyl-CoA production pathway, operating in parallel with acetyl-CoA synthetase 2 (ACSS2). Given persistent DNL after mitochondrial citrate carrier (CiC) and ACSS2 double knockout, we tested the contribution of exogenous and leucine-derived acetoacetate to acetoacetyl-CoA synthetase (AACS)-dependent DNL. CiC knockout increased acetoacetate-supplied hepatic acetyl-CoA production and DNL, indicating that ketones function as mitochondrial-citrate reciprocal DNL precursors. By delineating a mitochondrial-cytosolic DNL substrate supply network, these findings may inform strategies to therapeutically modulate DNL., Competing Interests: Declaration of interests The authors declare no competing interests., (Copyright © 2024 Elsevier Inc.

A considerable amount of recent research has focused on the role of artificial intelligence (AI) in colorectal cancer (CRC), aiming to improve outcomes in CRC. However, AI for young onset colorectal cancer (yoCRC)-defined as colorectal cancer in patients less than 50 years old-is not nearly as explored, and its role in the prevention, detection, and management of yoCRC remains largely unknown. To address this gap, we performed an integrative review on AI in yoCRC. We conducted a comprehensive literature search of PubMed, Medline (Ovid), and Embase for articles published from 2020 to 2024, adhering to specific inclusion and exclusion criteria. This integrative review involved gathering information from diverse research designs and literature sources. After removing duplicates and applying inclusion criteria, a total of 11 articles were included in the review. Our analysis identified one review discussing the importance of AI in yoCRC, three articles presenting research studies mentioning applications for yoCRC, and seven comprehensive investigations utilizing AI with a specific focus on yoCRC. The findings indicate that while AI in CRC is an evolving research field, there are few plans or implementations reported on how to incorporate AI specifically in yoCRC. Potential limitations of this review include the limited number of databases searched and the scope of search queries used. Nonetheless, this review highlights the need for more targeted research on AI applications in yoCRC. Future research can build upon the foundation of AI in CRC with adjustments to account for the increasing incidence of yoCRC., (© 2024 Wiley Periodicals LLC.)

Background: Rapidly emerging clinical trends offer the opportunity to amend guidance on issues pertaining to CF care delivery. A national survey was conducted to gather perspectives on CF care including potential adaptations to the care model to best meet the needs of this population., Methods: A survey instrument was developed to capture perspectives on CF care. People with CF (pwCF), including those post lung transplant, caregivers and care teams were surveyed. Descriptive statistics were calculated to characterize respondents and responses., Results: In-person, routine visits with the CF care teams were valued by survey respondents. However, reduced in-person visit frequency from the standard three-month interval was supported for individuals in a stable state of health. This was particularly true for pwCF ages two or older and on a modulator. Lung function, pulmonary exacerbation frequency, and transition periods were noted to influence preference for visit frequency. Integrating telehealth with remote monitoring in between visits was broadly supported. For shared care between CF teams and other medical providers (transplant teams and primary care providers (PCP)), good communication, easily accessible health records, and convenient locations were important., Conclusions: Survey findings support adapting CF care based on individual needs and life transitions. Themes identified can inform future areas of study and resource development to support successful modification of the CF care model and shared decision-making between patients and their care providers., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Interdisciplinary teams care for people with cystic fibrosis (pwCF) at specialized treatment centers. These teams have laid the foundation for the cystic fibrosis (CF) care model responsible for gains in health outcomes and quality of life within the CF community. However, the landscape of CF care is transforming, invigorated by new technologies, accessibility of cystic fibrosis transmembrane conductance regulator (CFTR) therapies, and increased utilization of telemedicine. In light of these advances, it is appropriate to re-evaluate the CF care team structure. This position paper offers guidance for the structure of a CF care center designed to meet the evolving needs of the CF community. Fundamental to the proposed center structure is recognition of pwCF and their families as integral members of their care teams, underpinning the necessity for shared decision making, awareness of social determinants of health, and active partnership between all healthcare professionals involved in the care of pwCF., Competing Interests: Declaration of competing interest The authors declare no conflict of interest. However, many authors are members of interdisciplinary teams and those CF Centers receive funding from the CF Foundation., (Copyright © 2024 European Cystic Fibrosis Society.

Specialized care is provided to people with cystic fibrosis (pwCF) by interdisciplinary teams nested within the CF Foundation's accredited care center network. This network allows for standardization of the care model, implementation of clinical care guidelines, efficient communication, and outcomes reporting. Recent developments have impacted this care model. Increased access to CFTR modulator therapies has improved overall health for many, although not all pwCF. The COVID-19 pandemic resulted in a rapid adoption of telemedicine and remote monitoring to ensure continuity of CF care. A collaboration of care providers, pwCF, and parent caregivers reevaluated key aspects of the current care model and considered potential modifications based on a widening range of needs. Available evidence was used to evaluate components of routine clinical practice and identify potential adaptations to care. The review included identification of patient characteristics warranting intensive monitoring, while embracing patient-centric care, and emphasizing the integration of telemedicine and at-home health technologies. Despite the changing landscape, the importance of the relationship between pwCF, their support system, and the care team was confirmed as a timeless and foundational aspect of the care model. Shared decision making, partnership, and coproduced care plans between pwCF and their CF care teams guide the best adaptations of the care model to support individual priorities and wellbeing. As health care advances and pwCF age, further research is needed to understand the impact of the care model on long-term health outcomes and to identify best practices that support pwCF to live longer healthier lives., Competing Interests: Declaration of competing interest The authors declare no conflict of interest., (Copyright © 2024 European Cystic Fibrosis Society.

Background: Prospective residents use program websites to glean information regarding parental leave policies. This study investigates the online availability and content of parental leave policies for general surgery residency programs., Methods: Parental leave policy information was collected from general surgery residency program and Graduate Medical Education (GME) websites. Descriptive statistics and multivariable logistic regression were used for analysis., Results: Of the 344 general surgery residency programs, parental leave policies were found on 6% of program and 52% of GME websites. Family Medical Leave Act policies were reported the most, followed by maternity, then paternity, and then adoption/other clauses. Academic programs, program location in the Southeastern US and larger program size were all significant predictors of online policy availability., Conclusions: General surgery parental leave policies vary and are not readily available online. These findings identify a significant opportunity for surgery residency programs to improve the disclosure of parental leave policy information., Competing Interests: Declaration of competing interest None declared, (Copyright © 2023 Elsevier Inc.

Objectives: In adults, an isolated low FEV 1 pattern (an FEV 1 below the lower limit of normal with a preserved FVC and FEV 1 /FVC) has been associated with the risk of developing airway obstruction. Our objective was to examine the prevalence, stability, and clinical significance of an isolated low FEV 1 pattern in the pediatric population., Methods: We conducted a retrospective study of spirometries from children ages 6-21 years and categorized tests into spirometry patterns according to published guidelines and recent literature. In a subgroup of tests with an isolated low FEV 1 pattern, we evaluated spirometry technique. We also examined the association of having a test with an isolated low FEV 1 pattern with clinical markers of disease severity in a subgroup of children with cystic fibrosis (CF)., Results: The isolated low FEV 1 pattern was uncommon across the 29,979 tests included (n = 645 [2%]). In the 263 children with an isolated low FEV 1 pattern who had a follow-up test performed, the most frequent spirometry pattern at last test was normal (n = 123 [47%]). A primary diagnosis of CF was associated with increased odds of having at least one test with an isolated low FEV 1 pattern (OR = 8.37, 95% CI = 4.70-15.96, p < .001). The spirometry quality in a subgroup of tests with an isolated low FEV 1 pattern (n = 50) was satisfactory. In the subgroup of children with CF (n = 102), those who had a test with an isolated low FEV 1 pattern had higher odds of using oral antibiotics in the last 12 months than those who had a normal pattern (OR = 3.50, 95% CI = 1.15-10.63, p = .03)., Conclusions: The isolated low FEV 1 pattern can occur repeatedly over time, usually transitions to a normal pattern, is not due to a poor spirometry technique, and could be clinically relevant in children with chronic lung diseases., (© 2024 The Authors.

Background: Few objective, real-time measurements of surgeon performance exist. The risk-adjusted cumulative sum is a novel method that can track surgeon-level outcomes on a continuous basis. The objective of this study was to demonstrate the feasibility of using risk-adjusted cumulative sum to monitor outcomes after colorectal operations and identify clinically relevant performance variations., Methods: The National Surgical Quality Improvement Program was queried to obtain patient-level data for 1,603 colorectal operations at a high-volume center from 2011 to 2020. For each case, expected risks of morbidity, mortality, reoperation, readmission, and prolonged length of stay were estimated using the National Surgical Quality Improvement Program risk calculator. Risk-adjusted cumulative sum curves were generated to signal observed-to-expected odds ratios of 1.5 (poor performance) and 0.5 (exceptional performance). Control limits were set based on a false positive rate of 5% (α = 0.05)., Results: The cohort included data on 7 surgeons (those with more than 20 cases in the study period). Institutional observed versus expected outcomes were the following: morbidity 12.5% (vs 15.0%), mortality 2.5% (vs 2.0%), prolonged length of stay 19.7% (vs 19.1%), reoperation 11.1% (vs 11.3%), and 30-day readmission 6.1% (vs 4.8%). Risk-adjusted cumulative sum accurately demonstrated within- and between-surgeon performance variations across these metrics and proved effective when considering division-level data., Conclusion: Risk-adjusted cumulative sum adjusts for patient-level risk factors to provide real-time data on surgeon-specific outcomes. This approach enables prompt identification of performance outliers and can contribute to quality assurance, root-cause analysis, and incentivization not only at the surgeon level but at divisional and institutional levels as well., (Published by Elsevier Inc.)

Background: Robotic surgery has emerged as an operative tool for many elective and urgent surgical procedures. The purpose of this study was to evaluate early surgical trainees' experiences and opinions of robotic surgery., Methods: An introductory robotic training course consisting of online da Vinci Xi/X training and in-person, hands on training was implemented for residents and medical students across surgical subspecialties at a single institution. A voluntary survey evaluating perceptions of and interest in robotic surgery and prior robotic surgery experience, as well as a basics of robotics quiz, was distributed to participants prior to the start of the in-person session. Descriptive statistics were used to evaluate the cohort., Results: 85 trainees participated in the course between 2020 and 2023, including 58 first- and second-year surgical residents (general surgery, urology, OB/GYN, and thoracic surgery) and 27 fourth-year medical students. 9.4% of participants reported any formal robotic surgery training prior to the session, with only 19% of participants reporting robotic operative experience. 52% of the participants knew of and/or had completed the da Vinci online course modules prior to the scheduled training session. Participants unanimously (100%) agreed that robotic surgery should be implemented into surgical training., Conclusions: There is rising enthusiasm for robotic surgery, yet early exposure and training remain infrequent and inconsistent amongst medical students and new surgical residents. A standardized introduction of multi-disciplinary robotic surgery training should be incorporated into medical school and/or early residency education to ensure surgical residents receive appropriate exposure and training to achieve competency., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Nine people with cystic fibrosis (pwCF) were found to have isolated elevations in serum total bilirubin after starting elexacaftor/tezacaftor/ivacaftor (ETI) that were associated with Gilbert's Syndrome. In longitudinal examination, total bilirubin levels increased substantially after initiation of ETI without elevations in liver transaminases in those with this syndrome. Because elevated bilirubin levels in Gilbert's Syndrome are benign, ETI was able to be continued in these individuals. Genetic testing for this relatively common syndrome should be strongly considered for pwCF experiencing isolated hyperbilirubinemia after starting ETI, since appropriate diagnosis may help pwCF avoid unnecessary interruption in this therapy with significant health benefits in CF., (© 2024 Wiley Periodicals LLC.)

Background: The nutritional status of children with cystic fibrosis (CF), as assessed by their body mass index percentile (BMIp), is a critical determinant of long-term health outcomes. While the intestinal microbiome plays an important role in nutrition, little is known regarding the relationship of the microbiome and BMIp in children with CF., Methods: Pediatric patients (< 18 years old) with CF and healthy comparison patients (HCs) were enrolled in the study and stool samples obtained. BMIp was categorized as Green Zone (BMIp > 50th), Yellow Zone (BMIp 25th-49th) and Red Zone (BMIp < 25th). Intestinal microbiome assessment was performed via 16S rRNA gene sequencing; microbial richness, diversity, and differential species abundance were assessed., Results: Stool samples were collected from 107 children with CF and 50 age-matched HCs. Compared to HCs, children with CF were found to have lower bacterial richness, alpha-diversity, and a different microbial composition. When evaluating them by their BMIp color zone, richness and alpha-diversity were lowest in those in the Red Zone. In addition, an unclassified amplicon sequence variant (ASV) of Blautia, a known butyrate-producing anaerobe, was of lowest abundance in children in the Red Zone., Conclusion: Children with CF have a dysbiotic intestinal microbiome with specific changes that accompany changes in BMIp. Longitudinal assessments of the microbiome and its metabolic activities over time are needed to better understand how improvements in the microbiome may improve nutrition and enhance long-term survival in children with CF., Competing Interests: Declaration of Competing Interest All authors declare that they have no conflicts of interest relevant to this work., (Copyright © 2023 European Cystic Fibrosis Society.

The intestinal microbiome influences growth and disease progression in children with cystic fibrosis (CF). Elexacaftor-tezacaftor-ivacaftor (ELX/TEZ/IVA), the newest pharmaceutical modulator for CF, restores the function of the pathogenic mutated CF transmembrane conductance regulator (CFTR) channel. We performed a single-center longitudinal analysis of the effect of ELX/TEZ/IVA on the intestinal microbiome, intestinal inflammation, and clinical parameters in children with CF. Following ELX/TEZ/IVA, children with CF had significant improvements in body mass index and percent predicted forced expiratory volume in one second, and required fewer antibiotics for respiratory infections. Intestinal microbiome diversity increased following ELX/TEZ/IVA coupled with a decrease in the intestinal carriage of Staphylococcus aureus , the predominant respiratory pathogen in children with CF. There was a reduced abundance of microbiome-encoded antibiotic resistance genes. Microbial pathways for aerobic respiration were reduced after ELX/TEZ/IVA. The abundance of microbial acid tolerance genes was reduced, indicating microbial adaptation to increased CFTR function. In all, this study represents the first comprehensive analysis of the intestinal microbiome in children with CF receiving ELX/TEZ/IVA.IMPORTANCECystic fibrosis (CF) is an autosomal recessive disease with significant gastrointestinal symptoms in addition to pulmonary complications. Recently approved treatments for CF, CF transmembrane conductance regulator (CFTR) modulators, are anticipated to substantially improve the care of people with CF and extend their lifespans. Prior work has shown that the intestinal microbiome correlates with health outcomes in CF, particularly in children. Here, we study the intestinal microbiome of children with CF before and after the CFTR modulator, ELX/TEZ/IVA. We identify promising improvements in microbiome diversity, reduced measures of intestinal inflammation, and reduced antibiotic resistance genes. We present specific bacterial taxa and protein groups which change following ELX/TEZ/IVA. These results will inform future mechanistic studies to understand the microbial improvements associated with CFTR modulator treatment. This study demonstrates how the microbiome can change in response to a targeted medication that corrects a genetic disease., Competing Interests: The authors declare no conflict of interest.

Introduction: Survey fatigue, a phenomenon where respondents lose interest or lack motivation to complete surveys, can undermine rigorously designed studies. Research during the COVID-19 pandemic capitalized on electronic surveys for maximum distribution, but with lower response rates. Additionally, it is unclear how survey fatigue affects surgical education stakeholders. This study aims to determine how response rates to an electronic survey, as a proxy for survey fatigue, differ among medical students (MS), surgery residents, and surgery faculty., Methods: Electronic surveys evaluating the surgical clerkship educational environment were distributed to third year MS, residents, and faculty at three academic institutions. Two reminder emails were sent. Groups with low response rates (<30%) received additional prompting. Response rates were compared using a chi-square test. Demographics of all survey respondents were collected and discussed. Baseline characteristics of the MS class, residency program, and Department of Surgery faculty from one institution were gathered and compared to respondents., Results: Surveys were sent to 283 third year MS, 190 surgery residents, and 374 surgical faculty. Response rates were 43%, 27%, and 20%, respectively (P < 0.0001). Male respondents, respondents of color, midlevel residents, and assistant professors had lower response rates compared to the baseline cohort., Conclusions: Our results demonstrate a statistically significant difference in survey response rates among MS, residents, and faculty, and have identified various targets for further investigation. Loss of interest in these groups should be further evaluated with a goal of decreasing survey fatigue, increasing survey response rates, and improving the quality of survey data collected., (Copyright © 2023 Elsevier Inc.

Objective: Individual differences in the perception of bodily sensations is known to be associated with affective symptomatology. However, the way people psychologically respond to everyday bodily sensations has not been examined in a systematic and balanced way. Thus, we developed the Bodily Sensations Response Scale (BSRS) to evaluate participants' self-reported cognitive, emotional, and behavioral responses to their bodily sensations. We investigated the scale's factor structure and its psychometric properties in two studies., Method: In Study 1 , 297 participants completed the 50-item BSRS and exploratory factor analysis (EFA) was performed on the responses. In Study 2 ( N = 284), confirmatory factor analysis (CFA) was used to confirm the factor structure of the 32-item BSRS identified in Study 1., Results: In Study 1, the EFA identified a 32-item three-factor solution as the best fit for the data. Factor 1 described a defeat response to bodily sensations, Factor 2 described an acceptance response, and Factor 3 described a sensitization response. In Study 2, the three-factor solution was shown not to be parsimonious. Rather, CFA identified that the 27-item BSRS had two interpretable factors (Defeat and Acceptance) that explained participants' psychological responses to bodily sensations. The Defeat subscale was moderately to strongly correlated with awareness of bodily sensations (i.e., Body Perception Questionnaire-Short Form scores) and depression, anxiety, and stress symptom severity (i.e., Depression Anxiety Stress Scales-21 scores), whereas the Acceptance subscale was unrelated or only slightly negatively correlated to awareness of bodily sensations and depression, anxiety, and stress symptoms., Conclusion: The 27-item BSRS provides a psychometrically robust assessment of the way in which people psychologically respond to everyday bodily sensations. The measure can assist researchers to better understand how people psychologically process their salient bodily sensations and how this is linked to psychopathology.

Patients with CF (pwCF) have high antibiotic use and an altered intestinal microbiome, known risk factors for infection with Clostridioides difficile. However, in adults with CF, C. difficile infection (CDI) is uncommon and asymptomatic colonization with C. difficile occurs frequently, for reasons that remain unclear. We investigated the rate, risk factors, and sequelae of asymptomatic C. difficile colonization in children with CF (cwCF). We identified that 32% of cwCF were colonized with C. difficile without acute gastrointestinal symptoms. Higher BMI and exposure to specific antibiotic classes (cephalosporins, fluoroquinolones, and vancomycin) were significantly associated with C. difficile colonization. No children developed symptomatic CDI in 90-days following enrollment., Competing Interests: Conflicts of Interest All authors declare that they have no conflicts of interest relevant to this work., (Copyright © 2022.

Drylands are key contributors to interannual variation in the terrestrial carbon sink, which has been attributed primarily to broad-scale climatic anomalies that disproportionately affect net primary production (NPP) in these ecosystems. Current knowledge around the patterns and controls of NPP is based largely on measurements of aboveground net primary production (ANPP), particularly in the context of altered precipitation regimes. Limited evidence suggests belowground net primary production (BNPP), a major input to the terrestrial carbon pool, may respond differently than ANPP to precipitation, as well as other drivers of environmental change, such as nitrogen deposition and fire. Yet long-term measurements of BNPP are rare, contributing to uncertainty in carbon cycle assessments. Here, we used 16 years of annual NPP measurements to investigate responses of ANPP and BNPP to several environmental change drivers across a grassland-shrubland transition zone in the northern Chihuahuan Desert. ANPP was positively correlated with annual precipitation across this landscape; however, this relationship was weaker within sites. BNPP, on the other hand, was weakly correlated with precipitation only in Chihuahuan Desert shrubland. Although NPP generally exhibited similar trends among sites, temporal correlations between ANPP and BNPP within sites were weak. We found chronic nitrogen enrichment stimulated ANPP, whereas a one-time prescribed burn reduced ANPP for nearly a decade. Surprisingly, BNPP was largely unaffected by these factors. Together, our results suggest that BNPP is driven by a different set of controls than ANPP. Furthermore, our findings imply belowground production cannot be inferred from aboveground measurements in dryland ecosystems. Improving understanding around the patterns and controls of dryland NPP at interannual to decadal scales is fundamentally important because of their measurable impact on the global carbon cycle. This study underscores the need for more long-term measurements of BNPP to improve assessments of the terrestrial carbon sink, particularly in the context of ongoing environmental change., (© 2023 John Wiley & Sons Ltd.)

Electronic information is a vital resource used by fellowship applicants. This study aimed to assess the completeness of colon and rectal surgery (CRS) fellowship program online information. Program information on the Association of Program Directors for Colon and Rectal Surgery (APDCRS) website as well as each institutional website was evaluated based on templated criteria. Sixty-eight accredited fellowship programs were identified. Six (9%) programs had complete profiles on the APDCRS platform, with an average of 3.5 details completed per program. Sixty-two (91%) websites were easily accessible. None of these contained all 28 criteria assessed and 47 (69%) contained less than half of assessed content. The most common data point was fellowship program description (96%), while board pass rate (1%) was the least common. Most CRS fellowship websites were grossly incomplete. Electronically available information is vital to fellowship applicants, and programs should try to provide easily accessible information about their program.
