Pilot Observational Study of Patient Reported Outcome Measures for Long COVID Patients in Virtual Integrative Medical Group Visits.

Background: Long COVID is a common, debilitating post-infectious illness for which effective management is unknown. Integrative Medical Group Visits (IMGV) are effective interventions for chronic conditions and could benefit Long COVID patients. More information is needed regarding existing patient reported outcome measures (PROMs) to evaluate efficacy of IMGV for Long COVID. Objective: This study assessed the feasibility of specific PROMS to evaluate IMGVs for Long COVID. Findings will inform future efficacy trials. Methods: The Perceived Stress Scale (PSS-10), General Anxiety Disorder two-question tool (GAD-2), Fibromyalgia Symptom Severity scale (SSS), and Measure Yourself Medical Outcome Profile (MYMOP®) were collected pre- and post-group by teleconferencing platform or telephone and compared using paired t-tests. Patients were recruited from a Long COVID specialty clinic where they participated in 2-hour - 8 weekly IMGV sessions online. Results: Twenty-seven participants enrolled and completed pre-group surveys. Fourteen participants were reachable by phone post-group and completed all pre and post PROMs (78.6% female, 71.4% non-Hispanic White, mean age 49). MYMOP® primary symptomatology was fatigue, shortness of breath and "brain fog". Symptoms decreased in interference when compared to pre-group levels (mean difference -1.3 [95% CI-2.2, -.5]). PSS scores decreased (-3.4 [95% CI -5.8, -1.1]), and GAD-2 mean difference was -1.43 (95% CI -3.12, .26). There were no changes in SSS scores of fatigue (-.21 [95% CI -.68,0.25]), waking unrefreshed (.00 [95%CI -.32, -.32]), or trouble thinking (-.21 [95% CI -.78,0.35]). Conclusion: All PROMs were feasible to administer via teleconferencing platform or telephone. The PSS, GAD-2 and MYMOP® are promising PROMs to track Long COVID symptomatology among IMGV participants. The SSS, while feasible to administer, did not change compared to baseline. Larger, controlled studies are needed to determine the efficacy of virtual IMGVs to address the needs of this large and growing population.

Accelerated epigenetic aging and myopenia in young adult cancer survivors.

BACKGROUND: Young adult cancer survivors experience early aging-related morbidities and mortality. Biological aging biomarkers may identify at-risk survivors and increase our understanding of mechanisms underlying this accelerated aging. METHODS: Using an observational study design, we cross-sectionally measured DNA methylation-based epigenetic age in young adult cancer survivors at a tertiary, academic state cancer hospital. Participants were a convenience sample of consecutively enrolled survivors of childhood, adolescent, and young adult cancers treated with either an anthracycline or alkylating agent, and who were at least 3 months post-treatment. Similarly aged healthy comparators were consecutively enrolled. Cancer treatment and treatment intensity were compared to DNA methylation-based epigenetic age and pace of aging. RESULTS: Sixty survivors (58 completing assessments, mean age 20.5 years, range 18-29) and 27 comparators (mean age 20 years, range 17-29) underwent DNA methylation measurement. Survivors were predominantly female (62%) and white (60%) and averaged nearly 6 years post-treatment (range 0.2-25 years). Both epigenetic age (AgeAccelGrim: 1.5 vs. -2.4, p < 0.0001; AgeAccelPheno 2.3 vs. -3.8, p = 0.0013) and pace of aging (DunedinPACE 0.99 vs. 0.83, p < 0.0001) were greater in survivors versus comparators. In case-case adjusted analysis, compared to survivors with normal muscle mass, myopenic survivors had higher AgeAccelGrim (2.2 years, 95% CI 0.02-4.33, p = 0.02), AgeAccelPheno (6.2 years, 2.36-10.09, p < 0.001), and DunedinPACE (0.11, 0.05-0.17, p < 0.001). CONCLUSIONS: Epigenetic age is older and pace of aging is faster in young adult cancer survivors compared to noncancer peers, which is evident in the early post-therapy period. Survivors with physiological impairment demonstrate greater epigenetic age advancement. Measures of epigenetic age may identify young adult survivors at higher risk for poor functional and health outcomes.

A Multidisciplinary Surgical Approach to Mediastinal Masses in Children.

The aim of this study is to demonstrate the safety and advantages of a multidisciplinary approach to surgical resection of mediastinal masses in children. Eight patients underwent resection of a mediastinal mass by a team involving both a pediatric general surgeon and pediatric cardiothoracic surgeon. One patient required rapid initiation of cardiopulmonary bypass to complete the tumor resection and repair an aortic injury that occurred when removing adherent tumor from the structure. Perioperative outcomes were excellent for all patients. This series shows that a multidisciplinary surgical approach can be potentially life saving.

Acute Leukemia Classification Using Transcriptional Profiles From Low-Cost Nanopore mRNA Sequencing.

PURPOSE: Most cases of pediatric acute leukemia occur in low- and middle-income countries, where health centers lack the tools required for accurate diagnosis and disease classification. Recent research shows the robustness of using unbiased short-read RNA sequencing to classify genomic subtypes of acute leukemia. Compared with short-read sequencing, nanopore sequencing has low capital and consumable costs, making it suitable for use in locations with limited health infrastructure. MATERIALS AND METHODS: We show the feasibility of nanopore mRNA sequencing on 134 cryopreserved acute leukemia specimens (26 acute myeloid leukemia [AML], 73 B-lineage acute lymphoblastic leukemia [B-ALL], 34 T-lineage acute lymphoblastic leukemia, and one acute undifferentiated leukemia). Using multiple library preparation approaches, we generated long-read transcripts for each sample. We developed a novel composite classification approach to predict acute leukemia lineage and major B-ALL and AML molecular subtypes directly from gene expression profiles. RESULTS: We demonstrate accurate classification of acute leukemia samples into AML, B-ALL, or T-lineage acute lymphoblastic leukemia (96.2% of cases are classifiable with a probability of > 0.8, with 100% accuracy) and further classification into clinically actionable genomic subtypes using shallow RNA nanopore sequencing, with 96.2% accuracy for major AML subtypes and 94.1% accuracy for major B-lineage acute lymphoblastic leukemia subtypes. CONCLUSION: Transcriptional profiling of acute leukemia samples using nanopore technology for diagnostic classification is feasible and accurate, which has the potential to improve the accuracy of cancer diagnosis in low-resource settings.

Frail young adult cancer survivors experience poor health-related quality of life.

BACKGROUND: Young adult cancer survivors experience frailty and decreased muscle mass at rates equivalent to much older noncancer populations, which indicate accelerated aging. Although frailty and low muscle mass can be identified in survivors, their implications for health-related quality of life are not well understood. METHODS: Through a cross-sectional analysis of young adult cancer survivors, frailty was assessed with the Fried frailty phenotype and skeletal muscle mass in relation to functional and quality of life outcomes measured by the Medical Outcomes Survey Short-Form 36 (SF-36). z tests compared survivors with US population means, and multivariable linear regression models estimated mean SF-36 scores by frailty and muscle mass with adjustments made for comorbidities, sex, and time from treatment. RESULTS: Sixty survivors (median age, 21 years; range, 18-29) participated in the study. Twenty-five (42%) had low muscle mass, and 25 were either frail or prefrail. Compared with US population means, survivors reported worse health and functional impairments across SF-36 domains that were more common among survivors with (pre)frailty or low muscle mass. In multivariable linear modeling, (pre)frail survivors (vs nonfrail) exhibited lower mean scores for general health (-9.1; P = .05), physical function (-14.9; P < .01), and overall physical health (-5.6; P = .02) independent of comorbid conditions. CONCLUSIONS: Measures of frailty and skeletal muscle mass identify subgroups of young adult cancer survivors with significantly impaired health, functional status, and quality of life independent of medical comorbidities. Identifying survivors with frailty or low muscle mass may provide opportunities for interventions to prevent functional and health declines or to reverse this process. LAY SUMMARY: Young adult cancer survivors age more quickly than peers without cancer, which is evidenced by a syndrome of decreased resilience known as frailty. The relationship between frailty (and one of its common components, decreased muscle mass) and quality of life among young adult cancer survivors was examined. Measuring decreased muscle mass and frailty identifies young survivors with poor quality of life, including worse general health, fatigue, physical function, and overall physical health, compared with nonfrail survivors. Interventions to address components of frailty (low muscle mass and weakness) may improve function and quality of life among young adult cancer survivors.

Gender Differences in Cardiothoracic Surgery Interest Among General Surgery Applicants.

BACKGROUND: Although the overall gender gap in medicine is narrowing, significant gender disparities remain in the cardiothoracic surgery (CTS) field; women represent only 7% of practicing surgeons and 20% of residents. The purpose of this study was to identify gender differences in CTS exposure and interest among fourth year medical students applying to general surgery residency. METHODS: An anonymous survey was emailed to general surgery residency applicants at a major academic program for the 2019 and 2020 application cycles. Data were stratified by gender and analyzed using the χ2 and t tests. RESULTS: Of the 303 responders to the survey, 44% were women. A total of 58% of women were unlikely to be interested in or were definitely not interested in pursuing a career in CTS compared with 35% of men (P < .05). Men were 2.5 times more likely than women to be interested in CTS (odds ratio, 2.5; 95% confidence interval, 1.5 to 4.1). More men had rotated through CTS (55% vs 44%; P = .04) and shadowed a cardiothoracic surgeon (41% vs 29%; P = .03). More than 30% of women interested in CTS reported mentorship as the most important factor in their decision. Mentorship and CTS rotations were both independently associated with CTS interest after adjusting for gender. CONCLUSIONS: Interest in CTS is disappointingly low among women and represents a troublesome disparity that must be addressed. Early exposure to CTS and more mentorship from cardiothoracic surgeons are critical to reverse the current trend. Further studies are necessary to determine factors limiting female exposure to CTS rotations and dissuading female applicants from pursuing careers in CTS.

Accelerated aging among childhood, adolescent, and young adult cancer survivors is evidenced by increased expression of p16INK4a and frailty.

BACKGROUND: Cellular senescence, measured by expression of the cell cycle kinase inhibitor p16INK4a , may contribute to accelerated aging in survivors of childhood, adolescent, and young adult cancer. The authors measured peripheral blood T-lymphocyte p16INK4a expression among pediatric and young adult cancer survivors, hypothesizing that p16INK4a expression is higher after chemotherapy and among frail survivors. METHODS: A cross-sectional cohort of young adult survivors and age-matched, cancer-free controls were assessed for p16INK4a expression and frailty. Newly diagnosed pediatric patients underwent prospective measurements of p16INK4a expression before and after cancer therapy. Frailty was measured with a modified Fried frailty phenotype evaluating sarcopenia, weakness, slowness, energy expenditure, and exhaustion. RESULTS: The cross-sectional cohort enrolled 60 survivors and 29 age-matched controls with a median age of 21 years (range, 17-29 years). The prospective cohort enrolled 9 newly diagnosed patients (age range, 1-18 years). Expression of p16INK4a was higher among survivors compared with controls (9.6 vs 8.9 log2 p16 units; 2-sided P = .005, representing a 25-year age acceleration in survivors) and increased among newly diagnosed patients from matched pretreatment to posttreatment samples (7.3-8.9 log2 p16 units; 2-sided P = .002). Nine survivors (16%) were frail and had higher p16INK4a expression compared with robust survivors (10.5 [frail] vs 9.5 [robust] log2 p16 units; 2-sided P = .055), representing a 35-year age acceleration among frail survivors. CONCLUSIONS: Chemotherapy is associated with increased cellular senescence and molecular age in pediatric and young adult cancer survivors. Frail survivors, compared with robust survivors, exhibit higher levels of p16INK4a , suggesting that cellular senescence may be associated with early aging in survivors.

Surgical management of catheter-related right atrial thrombus with superior vena cava syndrome A Case Report.

There are no consensus guidelines on the management of catheter-related right atrial thrombus. We present the case of a 29-year-old female with end-stage renal disease who was found to have a large right atrial thrombus associated with her tunneled dialysis catheter during preoperative workup for renal transplant. She exhibited signs and symptoms of superior vena cava syndrome and NYHA class III congestive heart failure. She was successfully treated with surgical thrombectomy and demonstrated rapid resolution of her symptoms postoperatively.

Robotic mitral valve repair in a type B hemophiliac.

Hemophilia B is a rare X-linked recessive disorder that places surgical patients at an increased risk of bleeding. Patients with hemophilia are now achieving near-normal life expectancies and therefore the number of these patients requiring cardiac surgery due to the development of age-related cardiovascular disease may increase. We present the case of a young male with hemophilia B who was diagnosed with severe symptomatic mitral regurgitation and underwent successful robotic mitral valve repair. To our knowledge, this is the first report of a patient with hemophilia B who underwent robotic mitral valve repair.

Evaluation of Cardiothoracic Surgery Residency and Fellowship Program Websites.

BACKGROUND: The internet is a valuable resource for residency and fellowship applicants when deciding where to apply or interview, yet program websites have shown critical deficiencies in accessibility and content. No analysis of cardiothoracic surgery program websites has been performed. METHODS: Online databases and Google were used to identify integrated, 4 + 3, and traditional cardiothoracic surgery residency and fellowship programs. The accessibility of websites from each of these sources was assessed and the presence or absence of content that may be relevant to applicants was evaluated by two reviewers. RESULTS: Eighty-nine active programs were identified and 86 had functional websites. Website content and accessibility were overall suboptimal in all 86 of these programs. Google was the most reliable means of accessing a program's website. Fifty percent of integrated program websites and 60% of traditional fellowship websites contained less than half of the content assessed. Information on 4 + 3 programs was extremely limited. CONCLUSIONS: Despite the value that a program's website could provide to applicants when making decisions during the application process, cardiothoracic surgery residency and fellowship websites remain difficult to access and are not uniformly providing information that may be important. Improving cardiothoracic website accessibility and content may have implications for attracting the most competitive applicants while limiting the financial and scheduling demands associated with the interview process. Creation of a current database containing standardized information relevant to applicants may improve applicants' ability to form an impression of a program before scheduling an interview.

An online survey on burden of illness among families with post-stem cell transplant mucopolysaccharidosis type I children in the United States.

BACKGROUND: Severe mucopolysaccharidosis type I (also known as Hurler syndrome) is a rare devasting recessive genetic disease caused by the deficiency of an enzyme. Hematopoietic stem cell transplant is the standard of care in the United States, usually conducted before the child is 3 years of age, but little is known about the continued medical and educational needs of the child after transplant. A greater understanding of the burden of illness on the primary caregiver is also needed. Therefore, this online survey sought to gather information on the burden of severe MPS I in the United States at least 1 year after transplant. RESULTS: Thirty-two respondents reported that children with severe MPS I have significant medical and educational needs after transplant. Healthcare resource use was frequent, especially in the outpatient setting specifically for bone, cardiac, and vision complications that were not relieved by HSCT. Twenty-five percent of the children had been hospitalized at least once in the last year and two had been hospitalized twice. The most common reasons for overnight hospitalizations included orthopedic surgeries and respiratory infections. Among children ages 5 and older, only 3 of 28 (11%) were able to attend school with no special support. While caregivers were generally satisfied with the healthcare services their child receives, 69% of working caregivers reported negative impact on their ability to conduct work tasks, and 54% of caregivers did not work so that they could care for the child. CONCLUSIONS: Results suggest that severe MPS I children continue to  require medical care and special support for education. Future research on the burden of illness on families affected by severe MPS I is needed to better understand total cost of care, and to identify therapies and interventions that reduce burden of illness. Future studies that compare cost of and access to health care in different countries may provide a more global view of the burden of MPS I.

Characterization and utilization of an international neurofibromatosis web-based, patient-entered registry: An observational study.

The neurofibromatoses (neurofibromatosis type 1, neurofibromatosis type 2 and schwannomatosis) are rare disorders having clinical manifestations that vary greatly from patient to patient. The rarity and variability of these disorders has made it challenging for investigators to identify sufficient numbers of patients with particular clinical characteristics or specific germline mutations for participation in interventional studies. Similarly, because the natural history of all types of neurofibromatosis (NF) is variable and unique for each individual, it is difficult to identify meaningful clinical outcome measures for potential therapeutic interventions. In 2012, the Children's Tumor Foundation created a web-based patient-entered database, the NF Registry, to inform patients of research opportunities for which they fit general eligibility criteria and enable patients to contact investigators who are seeking to enroll patients in approved trials. Registrants were recruited through CTF-affiliated NF clinics and conferences, through its website, and by word-of-mouth and social media. Following online consent, demographic information and details regarding manifestations of NF were solicited on the Registry website. Statistical analyses were performed on data from a cohort of 4680 registrants (the number of registrants as of October 9, 2015) who met diagnostic criteria for one of the 3 NF conditions. The analyses support our hypothesis that patient-reported symptom incidences in the NF Registry are congruent with published clinician-sourced data. Between April 26, 2013 and July 8, 2016, the registry has been useful to investigators in recruitment, particularly for observational trials, especially those for development of patient-reported outcomes.

Excess risk of temporomandibular disorder associated with cigarette smoking in young adults.

UNLABELLED: Evidence suggests that the effect of cigarette smoking on chronic pain is stronger in younger than older adults. This case-control study investigated whether age modified an effect of smoking on temporomandibular disorder (TMD) in 299 females aged 18 to 60 years. It also investigated the extent to which this relationship was explained by psychological profile, inflammatory response, and allergy. Cases were defined using the Research Diagnostic Criteria for Temporomandibular Disorders based on clinical examination. Psychological profile was evaluated using standardized instruments. Inflammatory response was evaluated with 11 cytokines isolated in plasma. History of allergy conditions was self-reported. Odds ratios (ORs) for the effect of smoking were calculated using binary logistic regression. Stratified analyses and the likelihood ratio test examined effect modification by smoking. Compared with nonsmokers, ever smokers aged <30 years had higher odds of TMD (OR = 4.14, 95% CI: 1.57, 11.35) than older adults (OR = 1.23, 95% CI: .55, 2.78) (P (effect modification) = .038). Adjustment for psychological profile, cytokines, and history of allergy-like conditions attenuated the effect by 45% to statistical nonsignificance. The main finding was reproduced with secondary analyses of 2 nationally representative surveys of adults conducted in the US and Australia. PERSPECTIVE: This study showed that smoking was associated with TMD risk in females, but only in young adulthood. It replicated this finding in 2 nationally representative surveys of females in the US and Australia. Findings may alert clinicians to recognize that smoking is a concern for TMD in younger female patients.

Perceived intensity and unpleasantness of cutaneous and auditory stimuli: an evaluation of the generalized hypervigilance hypothesis.

According to the Generalized Hypervigilance Hypothesis (GHH) of McDermid et al., the unpleasantness of sensory stimuli, rather than their modality, determines whether they will be perceptually amplified in hypervigilant persons. In a test of this idea, ratings of the intensity of sensations evoked by cutaneous and auditory stimuli were obtained from individuals with chronic myofascial pain (fibromyalgia, temporomandibular disorders), and from (less hypervigilant) healthy control participants. In each modality, the stimuli spanned a wide intensity range, with the weakest stimuli being affectively neutral and the strongest being distinctly unpleasant, as determined by unpleasantness ratings. The pain patients showed robust perceptual amplification of the cutaneous pressure stimuli, and modest amplification of the auditory stimuli. In both cases, perceptual amplification extended to even the lowest stimulus intensities, a result that is not consistent with the predictions of the GHH. An alternative formulation, the attentional gain control model of hypervigilance, is proposed, according to which those types of stimuli that are associated with pain are amplified because of the attention that is habitually directed toward them.

Association of various dimensions of hot flashes with systemic levels of gonadal steroids.

Hot flashes, the cardinal sign of menopausal vasomotor symptoms, are experienced by millions of women. The experience of hot flashes is characterized by significant inter- and intra-individual variability among women. The goals of this study were to compare concentrations of gonadal hormones between menopausal women with hot flashes (HF) and those with no HF, and to characterize the association between steroid levels and multiple dimensions of hot flashes. Menopausal women, with HF and with no HF, participated in four study sessions, one every 2 months. The Menopausal Vasomotor Symptom (MVS) survey was used to collect subjective data on various dimensions of hot flashes. Concentrations of gonadal hormones were measure at each bi-monthly session. Steroid levels were correlated to duration, frequency, length of each episode, timing, intensity, and bothersomeness of hot flashes. Data from twenty (n = 20) women with HF and fifteen (n = 15) with no HF with similar demographic profiles were analyzed. The results from the present study showed that systemic levels of estrone and progesterone were significantly lower in women experiencing HF than in asymptomatic women. There was a significant association between levels of estradiol, estrone, progesterone, and androstenedione, but not testosterone, with duration, frequency, timing, intensity, and bothersomeness of HF. The findings from this preliminary study suggest that management of symptoms associated with vasomotor HF should be individualized and guided by two factors: (i) thorough assessment of subjectively reported multiple dimensions of hot flashes, and (ii) levels of circulating gonadal steroids representing an average from 2-4 measures. This approach may lead to more targeted, effective, and safe management of vasomotor symptoms in the rapidly growing population of menopausal women.

Menopausal Vasomotor Symptoms (MVS) survey for assessment of hot flashes.

OBJECTIVES: During the menopause, 65%-80% of women experience hot flashes. Hot flashes can also occur after hysterectomy and may be experienced during cancer therapy. A very limited assessment of hot flashes is provided by currently available menopausal instruments. This study was performed to evaluate a new Menopausal Vasomotor Symptoms (MVS) survey as an instrument for a comprehensive and subjective assessment of hot flashes. METHODS: The MVS survey was designed to assess multiple dimensions of hot flashes and to be simple and easy to administer. Hot flashes and associated conditions were addressed with 39 closed-ended questions. Sixty-one qualified women, 40-58 years old, from the Dallas, Fort Worth Metroplex area were enrolled. Women experiencing hot flashes took the survey at baseline and then 14 days, 2 months, and 6 months later. Factor analysis was performed. Face and content validity, internal consistency, test-retest reliability, and sensitivity to changes were evaluated. RESULTS: Fifty-two women (85.2%) completed all study sessions. The MVS survey was found to have good face and content validity and good internal consistency (rhoKR = 0.87). Spearman rank-order correlation coefficients at the 14-day retest varied from 0.58 to 1.00. As a result of these analyses, the MVS survey was further refined. CONCLUSIONS: The MVS survey was found to be comprehensive, simple, valid, reliable, sensitive, and a convenient instrument for subjective assessment of various characteristics of hot flashes. The MVS survey may serve as a valuable clinical and research tool for measurement of hot flashes.
