Development and evaluation of a questionnaire to capture environmental and occupational inhalational exposures in adults with fibrotic interstitial lung disease.

BACKGROUND: Identification of exposures in patients with interstitial lung diseases (ILDs) is essential for diagnosis and management and can be facilitated through the use of exposure questionnaires. However, for most ILDs, a patient-focused questionnaire is lacking. Cognitive interviewing is a methodology used to evaluate sources of understanding and misunderstanding in a questionnaire and to provide evidence of content validity. We developed and refined a new exposure questionnaire for patients with fibrotic ILDs by using cognitive interviewing to establish its understandability and content validity. METHODS: An exposure assessment questionnaire was developed by a multidisciplinary team. Cognitive interviews with 24 patients with fibrosing ILDs were conducted by trained interviewers over the phone or Zoom using a semi-structured interview guide. The questionnaire was amended based on the interviewers' interpretation of sources of misunderstanding. The revised questionnaire was tested in a second round of cognitive interviews with a different group of 24 patients. RESULTS: Among the 48 patients who completed interviews, mean age was 61 years, 58.3% were male and 75.0% were white. Based on the first round of cognitive interviews, the multidisciplinary team modified the questions, organization, and instructions of the questionnaire to facilitate recall, adjust for exposures that were frequently misunderstood or required clarification, and focus on clinically relevant exposures. The revised questionnaire performed well in the second round of interviews. CONCLUSION: An exposure questionnaire, developed with input from patients, can be used to assess clinically relevant exposures in adults with fibrosing ILDs. This is the first questionnaire for all types of fibrosing ILD to have undergone content validation.

Sexuality Minority Status, Victimization, Mental Health, and Substance Use.

Background: Prior research suggests that sexual minority status is related to victimization, mental health issues, and substance use. However, few studies have sought to connect these relationships in a way supported by theory, and fewer have utilized probability and/or nationally representative samples. Objective: The current study seeks to test the relationships among these variables, guided by general strain theory (GST). Methods: One wave of the National Longitudinal Study of Adolescent to Adult Health dataset (Add Health) (N = 14,121) and path modeling in Mplus are utilized. Results: Models run separately by race/ethnicity suggest that the relationship among these variables largely support expectations from GST, but with some notable differences by race/ethnicity. Conclusion: Results suggest a relationship among these variables that concurs with criminological theorizing. Implications and limitations are discussed.

Classifying early infant feeding status from clinical notes using natural language processing and machine learning.

The objective of this study is to develop and evaluate natural language processing (NLP) and machine learning models to predict infant feeding status from clinical notes in the Epic electronic health records system. The primary outcome was the classification of infant feeding status from clinical notes using Medical Subject Headings (MeSH) terms. Annotation of notes was completed using TeamTat to uniquely classify clinical notes according to infant feeding status. We trained 6 machine learning models to classify infant feeding status: logistic regression, random forest, XGBoost gradient descent, k-nearest neighbors, and support-vector classifier. Model comparison was evaluated based on overall accuracy, precision, recall, and F1 score. Our modeling corpus included an even number of clinical notes that was a balanced sample across each class. We manually reviewed 999 notes that represented 746 mother-infant dyads with a mean gestational age of 38.9 weeks and a mean maternal age of 26.6 years. The most frequent feeding status classification present for this study was exclusive breastfeeding [n = 183 (18.3%)], followed by exclusive formula bottle feeding [n = 146 (14.6%)], and exclusive feeding of expressed mother's milk [n = 102 (10.2%)], with mixed feeding being the least frequent [n = 23 (2.3%)]. Our final analysis evaluated the classification of clinical notes as breast, formula/bottle, and missing. The machine learning models were trained on these three classes after performing balancing and down sampling. The XGBoost model outperformed all others by achieving an accuracy of 90.1%, a macro-averaged precision of 90.3%, a macro-averaged recall of 90.1%, and a macro-averaged F1 score of 90.1%. Our results demonstrate that natural language processing can be applied to clinical notes stored in the electronic health records to classify infant feeding status. Early identification of breastfeeding status using NLP on unstructured electronic health records data can be used to inform precision public health interventions focused on improving lactation support for postpartum patients.

Successful Extracorporeal Membrane Oxygenation Implementation at a Non-tertiary Medical Center: A Single-Center Experience.

The inexperience and limited resources at non-tertiary medical centers pose unique challenges to the successful development of an extracorporeal membrane oxygenation (ECMO) program. The current literature does not provide a detailed framework that addresses the unique challenges encountered at these facilities. We outline a proactive approach to developing an ECMO program and provide a retrospective analysis of patient demographics, clinical characteristics, ECMO configuration, duration of ECMO support, major adverse events, and survival to hospital discharge. Data are summarized using mean, median, percentages, standard deviation, and interquartile range. Eleven patients were cannulated between December 2021 to March 2023. The age range of the patients who received ECMO varied significantly, with the youngest being 25 years old and the oldest being 69 years old. The mean age was 38 years old, with a standard deviation of 15.9. Hypertension was the most common co-morbid condition occurring in 64% (n=7) of patients. Only one patient had a major adverse event, and survival to hospital discharge was 73% (n=8). Of the patients that survived hospital discharge, seven patients were discharged home and one to a rehabilitation facility. These findings suggest that the safe implementation of an ECMO program at a non-tertiary hospital with inexperienced staff and limited resources is feasible. Adherence to established guidelines is essential for new programs, especially with regard to patient selection. Furthermore, a proactive approach that emphasizes high-yield training techniques, patient management protocols, and strategies that mitigate adverse events may be the key to achieving survival rates that exceed those of larger academic hospitals.

SIRT3 overexpression in rat muscle does not ameliorate peripheral insulin resistance.

Reduced expression of the NAD+-dependent deacetylase, SIRT3, has been associated with insulin resistance and metabolic dysfunction in humans and rodents. In this study, we investigated whether specific overexpression of SIRT3 in vivo in skeletal muscle could prevent high-fat diet (HFD)-induced muscle insulin resistance. To address this, we used a muscle-specific adeno-associated virus (AAV) to overexpress SIRT3 in rat tibialis and extensor digitorum longus (EDL) muscles. Mitochondrial substrate oxidation, substrate switching and oxidative enzyme activity were assessed in skeletal muscles with and without SIRT3 overexpression. Muscle-specific insulin action was also assessed by hyperinsulinaemic-euglycaemic clamps in rats that underwent a 4-week HFD-feeding protocol. Ex vivo functional assays revealed elevated activity of selected SIRT3-target enzymes including hexokinase, isocitrate dehydrogenase and pyruvate dehydrogenase that was associated with an increase in the ability to switch between fatty acid- and glucose-derived substrates in muscles with SIRT3 overexpression. However, during the clamp, muscles from rats fed an HFD with increased SIRT3 expression displayed equally impaired glucose uptake and insulin-stimulated glycogen synthesis as the contralateral control muscle. Intramuscular triglyceride content was similarly increased in the muscle of high-fat-fed rats, regardless of SIRT3 status. Thus, despite SIRT3 knockout (KO) mouse models indicating many beneficial metabolic roles for SIRT3, our findings show that muscle-specific overexpression of SIRT3 has only minor effects on the acute development of skeletal muscle insulin resistance in high-fat-fed rats.

Which "weigh" to Go? Alternative Vancomycin Dosing Strategies in Obese Patients.

PurposeThis study aims to compare the performance of alternative weight-based vancomycin dosing strategies to traditional dosing in obese patients using area under the curve (AUC) monitoring. Methods: This retrospective study compared target attainment of an AUC between 400-600mcg*H/mL using alternative vancomycin dosing strategies. All patients received allometrically dosed vancomycin, with patient-specific AUCs calculated using 2 post-infusion steady-state vancomycin serum concentrations using the trapezoidal rule. Predicted AUCs were calculated using the following: 15 mg/kg total body weight (TBW), 15 mg/kg corrected body weight (CBW), and 12.5 mg/kg TBW. Predicted AUCs from the traditional 15 mg/kg TBW dosing were then compared to alternative dosing strategies using the predicted AUCs from 12.5 mg/kg TBW, 15 mg/kg CBW, and the actual AUCs calculated using allometrically scaled vancomycin dosing. The primary outcome was attainment of initial AUC within the target range of 400-600mcg*H/mL for each dosing method. Results: Eighty-four patients were included. When AUCs were compared to traditional 15 mg/kg dosing strategy, the CBW, 12.5 mg/kg, and allometric dosing strategies were significantly more likely to result in initial attainment of an AUC within a target range of 400-600 mcg*H/mL (P = 0.0003, 0.0135, and 0.0088, respectively). No significant differences were seen between each of the alternative dosing methods (P = 0.73). Conclusion: The 3 alternative vancomycin dosing strategies examined were all significantly more likely to achieve an initial AUC within the target range compared to traditional vancomycin dosing in obese patients. Clinicians should strongly consider one of these alternative dosing strategies for obese patients as opposed to traditional vancomycin dosing.

Liver-specific overexpression of SIRT3 enhances oxidative metabolism, but does not impact metabolic defects induced by high fat feeding in mice.

The mitochondrial enzyme SIRT3 is an NAD+-dependent deacetylase important in cell metabolism, and a decline in its protein expression or activity has been linked with insulin resistance in obesity, ageing and type 2 diabetes. While studies in SIRT3 knockout mice have dramatically improved our understanding of the function of SIRT3, the impact of increasing SIRT3 levels remains under-examined. In this study we investigated the effects of liver-specific SIRT3 overexpression in mice on mitochondrial function and metabolic profile in both isolated hepatocytes and in vivo. Primary hepatocytes overexpressing SIRT3 displayed increased oxygen consumption and a reduction in triglyceride accumulation. In mice with hepatic SIRT3 overexpression, increased fasting ß-hydroxybutyrate levels were observed, coupled with an increase in oxygen consumption in isolated mitochondria and increased substrate utilization in liver homogenates. However, metabolic profiling of mice exposed to either chow or high-fat diet revealed no effect of hepatic SIRT3 overexpression on glucose tolerance, body composition or tissue triglyceride accumulation. These findings suggest limited whole-body benefit of increasing hepatic SIRT3 during the development of diet-induced insulin resistance.

A cluster randomized controlled trial for a multi-level, clinic-based smoking cessation program with women in Appalachian communities: study protocol for the "Break Free" program.

BACKGROUND: The cervical cancer burden is high among women living in Appalachia. Cigarette smoking, a cervical cancer risk factor, is also highly prevalent in this population. This project aims to increase smoking cessation among women living in Appalachia by embedding a smoking cessation program within a larger, integrated cervical cancer prevention program. METHODS: The broader program, the Take CARE study, is a multi-site research collaborative designed to address three risk factors for cervical cancer incidence and mortality: tobacco use, human papillomavirus (HPV) infection, and cervical cancer screening. Break Free is a primary care clinic-based implementation program that aims to promote smoking cessation among female smokers in Appalachia by standardizing clinical practice protocols. Break Free includes: (1) implementation of a tobacco user identification system in the Electronic Health Record, (2) clinic staff and provider training on the Ask, Advise and Refer (AAR) model, (3) provider implementation of AAR to identify and treat women who want to quit smoking within the next 6 months, (4) facilitated access to cessation phone counseling plus pharmacotherapy, and (5) the bundling of Break Free tobacco cessation with HPV vaccination and cervical cancer screening interventions in an integrated approach to cervical cancer prevention. The study spans 35 Appalachian health clinics across 10 healthcare systems. We aim to enroll 51 adult female smokers per health system (total N = 510). Baseline and follow-up data will be obtained from participant (provider and patient) surveys. The primary outcome is self-reported 12-month point prevalence abstinence among enrolled patients. All randomized patients are asked to complete follow-up surveys, regardless of whether they participated in tobacco treatment. Data analysis of the primary aims will follow intent-to-treat methodology. Secondary outcomes will assess program implementation and cost effectiveness. DISCUSSION: Addressing high tobacco use rates is critical for reducing cervical cancer morbidity and mortality among women living in Appalachia. This study evaluates the implementation and effectiveness of a smoking cessation program in increasing smoking cessation among female smokers. If results demonstrate effectiveness and sustainability, implementation of this program into other health care clinics could reduce both rates of smoking and cervical cancer. Trial registration NCT04340531 (April 9, 2020).

Gestational diabetes and risk of breast cancer before age 55 years.

BACKGROUND: The history of gestational diabetes mellitus (GDM) has been associated with breast cancer risk in some studies, particularly in young women, but results of cohort studies are conflicting. METHODS: We pooled data from 257 290 young (age <55 years) women from five cohorts. We used multivariable Cox proportional-hazards regression to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between GDM history and risk of breast cancer, overall and by oestrogen receptor (ER) status, before age 55 years, adjusted for established breast cancer risk factors. RESULTS: Five percent of women reported a history of GDM and 6842 women reported an incident breast-cancer diagnosis (median follow-up = 16 years; maximum = 24 years). Compared with parous women without GDM, women with a history of GDM were not at increased risk of young-onset breast cancer overall (HR = 0.90; 95% CI: 0.78, 1.03) or by ER status (HR = 0.96; 95% CI: 0.79, 1.16 for ER-positive; HR = 1.07; 95% CI: 0.78, 1.47 for ER-negative). Compared with nulliparous women, parous women with a history of GDM had a lower risk of breast cancer overall (HR = 0.79; 95% CI: 0.68, 0.91) and of ER-positive (HR = 0.82; 95% CI: 0.66, 1.02) but not ER-negative (HR = 1.09; 95% CI: 0.76, 1.54) invasive breast cancer. These results were consistent with the HRs comparing parous women without GDM to nulliparous women. CONCLUSIONS: Results of this analysis do not support the hypothesis that GDM is a risk factor for breast cancer in young women. Our findings suggest that the well-established protective effect of parity on risk of ER-positive breast cancer persists even for pregnancies complicated by GDM.

E-cigarette sharing behavior among college students: An exploratory study.

INTRODUCTION: The purpose of this study was to explore sharing behavior among college students who use e-cigarettes. METHODS: A convenience sample of current e-cigarette users answered questionnaire items regarding sharing behavior (e.g., the number of people that have shared e-cigarettes, the settings that sharing takes place, reasons for sharing). RESULTS: Of the 121 participants, 24% shared e-cigarettes every day and 76% shared some days. The most common setting (91%) for sharing was at social gatherings, and participants shared most often (52%) with one or two people, which happened most often (99%) with friends. The top reason (80%) for sharing e-cigarettes was to feel the effects of nicotine. CONCLUSIONS: The finds support the need to address sharing behavior in youth e-cigarette use and the need for more stringent e-cigarette policies and cessation resources.

Perspectives of Pregnant and Breastfeeding Women on Participating in Longitudinal Mother-Baby Studies Involving Electronic Health Records: Qualitative Study.

BACKGROUND: Electronic health records (EHRs) hold great potential for longitudinal mother-baby studies, ranging from assessing study feasibility to facilitating patient recruitment to streamlining study visits and data collection. Existing studies on the perspectives of pregnant and breastfeeding women on EHR use have been limited to the use of EHRs to engage in health care rather than to participate in research. OBJECTIVE: The aim of this study is to explore the perspectives of pregnant and breastfeeding women on releasing their own and their infants' EHR data for longitudinal research to identify factors affecting their willingness to participate in research. METHODS: We conducted semistructured interviews with pregnant or breastfeeding women from Alachua County, Florida. Participants were asked about their familiarity with EHRs and EHR patient portals, their comfort with releasing maternal and infant EHR data to researchers, the length of time of the data release, and whether individual research test results should be included in the EHR. The interviews were transcribed verbatim. Transcripts were organized and coded using the NVivo 12 software (QSR International), and coded data were thematically analyzed using constant comparison. RESULTS: Participants included 29 pregnant or breastfeeding women aged between 22 and 39 years. More than half of the sample had at least an associate degree or higher. Nearly all participants (27/29, 93%) were familiar with EHRs and had experience accessing an EHR patient portal. Less than half of the participants (12/29, 41%) were willing to make EHR data available to researchers for the duration of a study or longer. Participants' concerns about sharing EHRs for research purposes emerged in 3 thematic domains: privacy and confidentiality, transparency by the research team, and surrogate decision-making on behalf of infants. The potential release of sensitive or stigmatizing information, such as mental or sexual health history, was considered in the decisions to release EHRs. Some participants viewed the simultaneous use of their EHRs for both health care and research as potentially beneficial, whereas others expressed concerns about mixing their health care with research. CONCLUSIONS: This exploratory study indicates that pregnant and breastfeeding women may be willing to release EHR data to researchers if researchers adequately address their concerns regarding the study design, communication, and data management. Pregnant and breastfeeding women should be included in EHR-based research as long as researchers are prepared to address their concerns.

Perspectives of pregnant and breastfeeding women on longitudinal clinical studies that require non-invasive biospecimen collection - a qualitative study.

BACKGROUND: Investigation of the microbiome during early life has stimulated an increasing number of cohort studies in pregnant and breastfeeding women that require non-invasive biospecimen collection. The objective of this study was to explore pregnant and breastfeeding women's perspectives on longitudinal clinical studies that require non-invasive biospecimen collection and how they relate to study logistics and research participation. METHODS: We completed in-depth semi-structured interviews with 40 women who were either pregnant (n = 20) or breastfeeding (n = 20) to identify their understanding of longitudinal clinical research, the motivations and barriers to their participation in such research, and their preferences for providing non-invasive biospecimen samples. RESULTS: Perspectives on research participation were focused on breastfeeding and perinatal education. Participants cited direct benefits of research participation that included flexible childcare, lactation support, and incentives and compensation. Healthcare providers, physician offices, and social media were cited as credible sources and channels for recruitment. Participants viewed lengthy study visits and child protection as the primary barriers to research participation. The barriers to biospecimen collection were centered on stool sampling, inadequate instructions, and drop-off convenience. CONCLUSION: Women in this study were interested in participating in clinical studies that require non-invasive biospecimen collection, and motivations to participate center on breastfeeding and the potential to make a scientific contribution that helps others. Effectively recruiting pregnant or breastfeeding participants for longitudinal microbiome studies requires protocols that account for participant interests and consideration for their time.

Case Study of a Comprehensive Team-Based Approach to Increase Colorectal Cancer Screening.

Introduction: Colorectal cancer is the second leading cause of cancer deaths among men and women in West Virginia. In addition, 51% of all colorectal cancers diagnosed in West Virginia from 2012 to 2016 were detected at either regional (31%) or distant (20%) stages indicating a need for improved early detection. Methods: West Virginia University Cheat Lake Physicians participated in the West Virginia Program to Increase Colorectal Cancer Screening, a program of Cancer Prevention and Control at the WVU Cancer Institute. As a result, Cheat Lake Physicians assembled a team of health care professionals to implement evidence-based interventions and system changes including provider assessment and feedback, patient reminders, accurate data capture, and tracking of CRC screening tests. Results: These efforts resulted in a 15.8% increase in colorectal cancer screening rates within one year of implementation. Additionally, the clinic achieved a 66% return rate for Fecal Immunochemical Test kits, an inexpensive, stool-based colorectal cancer screening test. Implications: The utilization of a team-based approach to patient care yields positive results that can be carried over to other cancer and disease prevention efforts in primary care clinics.

Gender, Bullying Victimization, Depressive Symptoms, and Suicidality.

Bullying victimization can have serious consequences for adolescents. This article examines the association between traditional and cyberbullying victimization, depressive symptoms, and suicidality in a national school-based sample, utilizing general strain theory (GST) as a guide to how these variables might relate to each other. We additionally examine whether the associations between these variables differ by gender. Results suggest that traditional and cyberbullying victimization have significant, positive associations with both depressive symptoms and suicidality. Results are partly supportive of the full model suggested by GST, with the associations between bullying and suicidality being weakened in some models when accounting for depressive symptoms. Gender differences also emerge. These findings are discussed in relation to their relevance for policy and theory.

Coaching Strategies Used to Support Interprofessional Teams in 3 Primary Care Centers.

PURPOSE/AIMS: Clinical nurse specialists and other advanced practice registered nurses use healthcare team coaching to foster interprofessional practice and enhance healthcare quality. Although coaching has been shown to support positive changes in healthcare, little is known about how coaching strategies are used in practice. The purpose of this study was to describe the strategies used by an experienced healthcare team coach tasked with advancing interprofessional care and teamwork in primary care clinics. METHODS: This qualitative description study was part of a larger project that included an objective to increase interprofessional practice in 3 primary care clinics in the midwestern United States. Data drawn from 35 audio-recorded and transcribed coaching telephone calls were analyzed using content analysis. RESULTS: Twelve coaching strategies were identified and divided into the following groups: (a) enhancing team development, (b) affirming the work of the team, (c) facilitating progress, (d) providing resources, and (e) connecting work to theoretical frameworks. CONCLUSIONS: The coaching strategies described in this study can inform the work of clinical nurse specialists and other advanced practice registered nurses charged with advancing interprofessional collaborative practice. Future research is recommended to examine the efficacy of strategies and develop a comprehensive model of healthcare team coaching.

A Qualitative Study of Pregnant Women's Perspectives on Antibiotic Use for Mom and Child: Implications for Developing Tailored Health Education Interventions.

The overutilization of antibiotics during pregnancy and early life are associated with adverse health outcomes for mothers and infants. In this study, we explored pregnant women's opinions and concerns of antibiotics and how perceptions may affect their health-related decision-making. We conducted 18 in-depth, semi-structured interviews with pregnant women and used the Health Belief Model (HBM) as a framework to analyze the data. We found that mothers generally understood the benefits of antibiotics and were aware that antibiotics are clinically effective for treating bacterial infections. Importantly, perceived barriers related to antibiotic use included concerns regarding the impact of antibiotics on breastfeeding efficacy, microbial health, and societal factors such as antimicrobial resistance. The prescription of antibiotics by a healthcare provider was a cue to action for women, as they trusted providers to recommend medications that were safe for them and their infants. Overall, mothers shared that receiving education on the effects of antibiotics would improve their self-efficacy and decision-making surrounding the use of antibiotics for treating illness. Implications for tailored perinatal health education interventions to enhance antibiotic use, knowledge, and decision-making are discussed.

Noninvasive Abdominoplasty.

Noninvasive and minimally invasive treatments are increasingly supplanting, or complimenting, abdominoplasty. For optimal delivery of patient care and to maintain a dominant share of the body-contouring market, plastic surgeons need to embrace these new technologies. High capital purchases, costly disposables, maintenance fees, lack of experience, conflicting anecdotal reports, energy-related complications, marketing hyperbole, and rapid obsolescence are formidable barriers to this adoption. Receptive plastic surgeons may be best served by accepting brief short-term retrospective reports by reputable innovative body contouring surgeons who present a succinct and clinically supported message.

Nasal Obstruction and Rhinoplasty: A Focused Literature Review.

BACKGROUND: There is a significant variation in the assessment, treatment, and outcomes of nasal airway obstruction and management in the published literature. This study aimed to: (1) define key components of the nasal airway, (2) identify frequent causes of nasal obstruction, and (3) review existing treatment methods. METHODS: A systematic review of the literature was performed, and 135 studies were included via the following criteria: English, human subjects, and a primary endpoint of nasal airway improvement. Exclusion criteria were: abstract only, no airway data, pediatric patients, cleft rhinoplasty, sleep apnea, isolated traumatic nasal reconstruction, and cadaveric-only or animal studies. RESULTS: The relevant obstructive sites include the ENV, septum, inferior turbinates, INV, and nasal bones. Addressing the alar rim alone may be insufficient, and inspection of the lateral wall and crura may be indicated. Correction of septal deviation involves attention to the bony base. Mucosal sparing treatment of inferior turbinates improves outcomes. INVs are a major source of nasal obstruction, and treatment includes spreader grafts. The bony nasal vault can contribute to nasal obstruction, including due to surgical osteotomies. CONCLUSIONS: Anatomic causes of airway obstruction include the alar rims and lateral nasal walls, deviated nasal septum, inferior turbinate hypertrophy, decreased INV angle, and narrowed nasal bones. Treatments include graft placement; septoplasty; mucosal sparing turbinectomy; and lateral wall support. Pitfalls include failing to address the bony septum, over-resection of inferior turbinates, and narrowing of the nasal vault. Appreciation of airway management during rhinoplasty will improve functional outcomes. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.
