RESUMO
BACKGROUND: Dysgeusia is a common but understudied complication in patients undergoing autologous hematopoietic cell transplantation (auto-HCT). We assessed the feasibility of using chemical gustometry (CG) to measure dysgeusia and explored its associations with symptom burden, nutrition, chemotherapy pharmacokinetics (PK), and the oral microbiome. METHODS: We conducted a single-center, prospective feasibility study (NCT03276481) of patients with multiple myeloma undergoing auto-HCT. CG was performed longitudinally testing five flavors (sweet, sour, salty, bitter, umami) to calculate a total taste score (maximum score, 30). We measured caloric intake and patient-reported symptoms, assessing their correlation with oral microbiota composition and salivary and blood melphalan PK exposure. RESULTS: Among all 45 patients, 39 (87%) completed at least four (>60%) and 22 (49%) completed all six CG assessments. Median total CG scores remained stable over time but were lowest at day +7 (27, range 24-30) with recovery by day +100. Symptom burden was highest by day +10 (area under the curve, 2.9; range, 1.0-4.6) corresponding with the lowest median overall caloric intake (1624 kcal; range, 1345-2267). Higher serum/salivary melphalan levels correlated with higher patient-reported dysgeusia and lower caloric intake. Oral microbiota α-diversity was stable early and increased slightly by day +100. CONCLUSIONS: Assessment of dysgeusia by CG is feasible after auto-HCT. Most dysgeusia, symptom burden, and lowest caloric intake occurred during the blood count nadir. Higher melphalan concentrations correlated with more dysgeusia and poorer caloric intake. Future studies will aim to modulate melphalan exposure by PK-targeted dosing and characterize patient taste preferences to personalize diets for improved nutritional intake. LAY SUMMARY: Taste changes after cancer treatments are very common. We used chemical gustometry (taste testing) to study taste changes and to better understand why patients with multiple myeloma experience this symptom after autologous hematopoietic cell transplantation. We found that taste testing was feasible, taste changes peaked when blood counts were lowest, and most patients recovered their taste by 100 days after transplantation. Taste changes correlated with lower food intake and with higher levels of chemotherapy in the body. Future work will focus on using personalized chemotherapy doses to reduce taste changes and to match patients' individual taste preferences with their diets.

BACKGROUND: Among women who are undergoing in vitro fertilization (IVF), the transfer of frozen embryos has been shown to result in a higher rate of live birth than the transfer of fresh embryos in those with infertility associated with the polycystic ovary syndrome. It is not known whether frozen-embryo transfer results in similar benefit in women with infertility that is not associated with the polycystic ovary syndrome. METHODS: We randomly assigned 782 infertile women without the polycystic ovary syndrome who were undergoing a first or second IVF cycle to receive either a frozen embryo or a fresh embryo on day 3. In the frozen-embryo group, all grade 1 and 2 embryos had been cryopreserved, and a maximum of two embryos were thawed on the day of transfer in the following cycle. In the fresh-embryo group, a maximum of two fresh embryos were transferred in the stimulated cycle. The primary outcome was ongoing pregnancy after the first embryo transfer. RESULTS: After the first completed cycle, ongoing pregnancy occurred in 142 of 391 women (36.3%) in the frozen-embryo group and in 135 of 391 (34.5%) in the fresh-embryo group (risk ratio in the frozen-embryo group, 1.05; 95% confidence interval [CI], 0.87 to 1.27; P=0.65). Rates of live birth after the first transfer were 33.8% and 31.5%, respectively (risk ratio, 1.07; 95% CI, 0.88 to 1.31). CONCLUSIONS: Among infertile women without the polycystic ovary syndrome who were undergoing IVF, the transfer of frozen embryos did not result in significantly higher rates of ongoing pregnancy or live birth than the transfer of fresh embryos.

PURPOSE: In vitro maturation (IVM) is an alternative to in vitro fertilization (IVF) for women at high risk of developing ovarian hyperstimulation syndrome (OHSS). This study determined the effectiveness and safety of a freeze-only strategy versus fresh embryo transfer (ET) after IVM with a pre-maturation step (CAPA-IVM) in women with a high antral follicle count (AFC). METHODS: This randomized, controlled pilot study (NCT04297553) was conducted between March and November 2020. Forty women aged 18-37 years with a high AFC (≥24 follicles in both ovaries) undergoing one cycle of CAPA-IVM were randomized to a freeze-only strategy with subsequent frozen ET (n = 20) or to fresh ET (n = 20). The primary endpoint was ongoing pregnancy resulting in live birth after the first ET of the started treatment cycle. RESULTS: The ongoing pregnancy rate in the freeze-only group (65%) was significantly higher than that in the fresh ET group (25%; p = 0.03), as was the live birth rate (60% versus 20%; p = 0.02). Clinical pregnancy rate was numerically, but not significantly, higher after frozen versus fresh ET (70% versus 35%; p = 0.06), while the number of day 3 or good quality embryos, endometrial thickness on the day of oocyte pick-up, implantation rate, and positive pregnancy test rate did not differ significantly between groups. No cases of OHSS were observed, and miscarriage and multiple pregnancy rates were similar in the two groups. CONCLUSIONS: These findings suggest that the effectiveness of CAPA-IVM could be improved considerably by using a freeze-only strategy followed by frozen ET in subsequent cycles.

BACKGROUND: The Institute of Medicine reported that more than 1.5 million preventable adverse drug events occur annually in the United States. Comprehensive Medication Management (CMM) is the medication review process to improve clinical outcomes, enhance patient adherence, reduce drug therapy problems and reduce health care costs. University of Texas (UT) Physicians implemented a CMM program in several community-based clinics. We evaluated the effectiveness of CMM to reduce drug therapy problems and achieve medical cost savings. METHODS: This was a retrospective, observational study of CMM participants from October 2015 to September 2016. Program participants included patients aged 18 years or older who had taken more than 4 prescribed medications and were diagnosed with at least one of the following chronic diseases: hypertension, congestive heart failure, chronic obstructive pulmonary disease, asthma or diabetes. Under the CMM program, a clinical pharmacist reviewed patients' electronic health records and created action plans to resolve identified drug problems. As part of the evaluation of the clinical process, two independent physicians conducted peer review on the recommendations issued by the pharmacist in order to establish inter-rater reliability of drug therapy problems and potential consequent medical services. The drug therapy problems were identified and classified into four categories: indication, effectiveness, safety and/or compliance. The average cost of avoided medical services was obtained based on cost extrapolations from the literature, combined with hospital discharge data. Potential medical services avoided were linked to the average cost of those services to calculate the total cost savings of the program from the payers' perspective. RESULTS: By reviewing electronic health records of 3280 patients, the pharmacist identified 301 drug therapy problems and resolved 49.8% of these problems with collaboration from the patient's primary care physician or care team. The most commonly identified drug problems were related to potentially adverse drug reactions or inappropriate drug dosage. The CMM program resulted in potential cost savings of $1,143,015. CONCLUSIONS: The CMM program resolved medication therapy problems among program participants and achieved significant health care cost savings.

The COVID-19 pandemic led to delays in routine preventative primary care and declines in HPV immunization rates. Providers and healthcare organizations needed to explore new ways to engage individuals to resume preventive care behaviors. Thus, we evaluated the effectiveness of using customized electronic reminders with provider recommendations for HPV vaccination to increase HPV vaccinations among adolescents and young adults, ages 9-25. Using stratified randomization, participants were divided into two groups: usual care (control) (N = 3703) and intervention (N = 3705). The control group received usual care including in-person provider recommendations, visual reminders in exam waiting rooms, bundling of vaccinations, and phone call reminders. The intervention group received usual care and an electronic reminder (SMS, email or patient portal message) at least once, and up to three times (spaced at an interval of 1 reminder per month). The intervention group had a 17% statistically significantly higher odds of uptake of additional HPV vaccinations than the usual care group (Adjusted Odds Ratio: 1.17, 95% CI: 1.01-1.36). This work supports previous findings that electronic reminders are effective at increasing immunizations and potentially decreasing healthcare costs for the treatment of HPV-related cancers.
RESUMO
There are no standard treatments to prevent or hasten the recovery from severe conditioning-regimen-induced thrombocytopenia occurring after autologous hematopoietic cell transplantation (auto-HCT). We conducted an open-label, single-arm pilot study of romiplostim, a thrombopoietin receptor agonist, to enhance platelet recovery in patients with multiple myeloma or lymphoma undergoing auto-HCT. All patients were treated weekly with romiplostim starting day +1 after auto-HCT until the platelet count was >50 × 109/L without transfusion. Compared with contemporary retrospective data from romiplostim-naïve patients (N = 853), romiplostim-treated patients (N = 59) had a similar median number of days of grade 4 thrombocytopenia or days requiring transfusions, time to platelet engraftment, and number of platelets transfusions during the auto-HCT. However, romiplostim-treated patients had enhanced platelet recovery to normal values beginning at approximately day +15. In matched cohort multivariable analyses, romiplostim treatment was associated with higher platelet counts by an average of 40 × 109/L (95% confidence interval (CI) (14, 67), P = .003) and 118 × 109/L (95% CI [84, 152], P<.001) at days +21 and +30, respectively, compared with those of no romiplostim. Only 1 adverse event was deemed possibly attributable to romiplostim: a low-risk pulmonary embolism in a patient with multiple myeloma. In conclusion, romiplostim showed promising activity and safety after auto-HCT, but the improvement in platelet counts occurred later than the goal of shortening the duration and depth of the platelet nadir. This trial was registered at www.clinicaltrials.gov (#NCT04478123).

The interplay between magnetism and electronic band topology enriches topological phases and has promising applications. However, the role of topology in magnetic fluctuations has been elusive. Here, we report evidence for topology stabilized magnetism above the magnetic transition temperature in magnetic Weyl semimetal candidate CeAlGe. Electrical transport, thermal transport, resonant elastic X-ray scattering, and dilatometry consistently indicate the presence of locally correlated magnetism within a narrow temperature window well above the thermodynamic magnetic transition temperature. The wavevector of this short-range order is consistent with the nesting condition of topological Weyl nodes, suggesting that it arises from the interaction between magnetic fluctuations and the emergent Weyl fermions. Effective field theory shows that this topology stabilized order is wavevector dependent and can be stabilized when the interband Weyl fermion scattering is dominant. Our work highlights the role of electronic band topology in stabilizing magnetic order even in the classically disordered regime.
RESUMO
BACKGROUND: Though the association between anxiety disorders and suicidal behavior is well-described, the impact of anxiety symptoms on suicidal thoughts and behaviors (STB) across different mood disorders is still unclear. METHODS: We performed a registry-based retrospective study utilizing outcome measure data collected by the National Network of Depression Centers (NNDC), a nationwide nonprofit consortium of 26 leading clinical and academic member centers in the United States. The sample consisted of 2607 outpatients with mood disorders (major depressive disorder or bipolar disorders). Demographic and clinical variables were compared based on the presence or absence of STB and severity of anxiety symptoms (minimal, mild, moderate, and severe). Univariate and multivariable logistic regressions were conducted to examine the correlations of STB, considering multicollinearity. RESULTS: Patients with mild, moderate, and severe anxiety symptoms had higher odds of STB than those with minimal symptoms. Gender, marital status, age, and depressive symptoms were other strong predictors of STB. There was no difference in the odds of STB between patients with major depressive disorder (MDD) and those with bipolar disorders (BD). However, the odds of suicidal ideation were slightly lower among patients with BD than those with MDD. LIMITATIONS: Our sample was comprised only of outpatients, limiting the generalization of our findings. Other limitations include the lack of structured interviews for diagnostic characterization of the patients and the utilization of data on anxiety and mood obtained solely through self-report scales. CONCLUSIONS: We found a cross-sectional association between the severity of anxiety symptoms and STB among patients with mood disorders. This study demonstrates the need for a suicide risk assessment in patients with mood disorders reporting anxiety symptoms.

Background Longitudinal Integrated Clerkships (LICs) are innovative educational models that allow medical student continuity with patients, preceptors, colleagues, and health care systems. Given their benefits, the number of LICs continues to increase. We share a pilot model for an ophthalmology LIC curriculum at the University of Colorado School of Medicine targeted for students to see patients through transitions of care. Methods A needs assessment was performed including literature search, interviews with expert faculty, and a precurricular student questionnaire. Based on our findings, we developed a pilot two-part curriculum consisting of an introductory lecture and a half-day clinical experience designed to integrate patient eye care into the LIC model. At the end of the year, students completed a questionnaire assessing attitude, confidence, and knowledge. Precourse data were collected from students in the academic year (AY) 2018/2019 to aid with the needs assessment. Postcourse data were collected after completion of the curriculum from students in AY 2019/2020. Data from questionnaire were intended to improve our curricular experience. Results Our curriculum was piloted between the 2019 and 2020 AY. The completion rate of our curriculum was 100%. The questionnaire response rate was 90% in pre- and postcurricular groups ( n =15/17 and n =9/10, respectively). Hundred percent of students from both groups responded that it is "very important"/"important" for all physicians to be able to identify when ophthalmology referral is indicated. After the intervention, there were significant differences in the rate of students responding that they were "confident" diagnosing acute angle-closure glaucoma (36 vs. 78%, p =0.04), treating a chemical burn (20 vs 67%, p =0.02), and diagnosing viral conjunctivitis (27 vs. 67%); 90% of students reported increased confidence in longitudinal care of patients in the eye clinic. Conclusions Medical students believe in the importance of ophthalmic education regardless of their specialty of choice. We present a pilot model to introduce ophthalmology within an LIC model. Future studies with a larger sample are needed to determine the impact of this model in terms of knowledge acquisition and relationship between curriculum and ophthalmology interest among students. Our curriculum can be adapted to other underrepresented specialties in the medical school curriculum and is easily exportable to other LICs.
RESUMO
BACKGROUND: Palliative care aims to improve or maintain quality of life for patients with life-limiting or life-threatening diseases. Limited research shows that palliative care is associated with reduced intensive care unit length of stay and use of high-cost resources. METHODS: This was an observational, non-experimental comparison group study on all patients 18 years or older admitted to any intensive care unit (ICU) at Memorial Hermann - Texas Medical Center for 7 to 30 days from August 2013 to December 2015. Length of stay (LOS) and hospital costs were compared between the treatment group of patients with palliative care in the ICU and the control group of patients with usual care in the ICU. To adjust for confounding of the palliative care consultation on LOS and hospital cost, an inverse probability of treatment weighted method was conducted. Generalized linear models using gamma distribution and log link were estimated. All costs were converted to 2015 US dollars. RESULTS: Mean LOS was 13 days and mean total hospital costs were USD 58,378. In adjusted and weighted analysis, LOS for the treatment group was 8% longer compared to the control group. The mean total hospital cost was estimated to decrease by 21% for the treatment group versus the control group. We found a reduction of USD 33,783 in hospital costs per patient who died in the hospital and reduction of USD 9113 per patient discharged alive. CONCLUSION: Palliative care consultation was associated with a reduction in the total cost of hospital care for patients with life-limiting or life-threatening diseases.
RESUMO
BACKGROUND AND OBJECTIVE: Understanding the mental health impact of the COVID-19 pandemic on persons receiving COVID-19 testing will help guide mental health interventions. We aimed to determine the association between sociodemographic factors and mental health symptoms at 8 weeks (baseline) after a COVID-19 test, and compare prevalence of mental health symptoms at baseline to those at 16-week follow-up. MATERIALS AND METHODS: Prospective cohort study of adults who received outpatient COVID-19 testing at primary care clinics. Logistic regression analyses were used to assess the association between sociodemographic characteristics and COVID-19 test results with mental health symptoms. Mental health symptoms reported at baseline were compared to symptoms at 16 weeks follow-up using conditional logistic regression analyses. RESULTS: At baseline, a total of 124 (47.51%) participants reported at least mild depressive symptoms, 110 (42.15%) participants endorsed at least mild anxiety symptoms, and 94 participants (35.21%) endorsed hazardous use of alcohol. Females compared to males were at increased risk of at least mild depressive symptoms at baseline (Adjusted Odds Ratio (AOR): 2.08; 95% CI: 1.14-3.79). The odds of at least mild depressive symptoms was significantly lower among those residing in zip codes within the highest quartile compared to lowest quartile of household income (AOR: 0.37; 95% CI: 0.17-0.81). Also, non-Hispanic Whites had significantly higher odds of reporting hazardous alcohol use compared to non-Whites at baseline (AOR: 1.94; 95% CI: 1.05-3.57). The prevalence of mental health symptoms remained elevated after 16 weeks. CONCLUSION AND RELEVANCE: We found a high burden of symptoms of depression and anxiety as well as hazardous alcohol use in a diverse population who received testing for COVID-19 in the primary care setting. Primary care providers need to remain vigilant in screening for symptoms of mental health disorders in patients tested for COVID-19 well after initial testing.

OBJECTIVE: To compare the effectiveness of cervical pessary to vaginal progesterone for the prevention of preterm birth in women with twin pregnancies and short cervix. METHODS: This randomized controlled trial was conducted at My Duc Hospital, Vietnam. Asymptomatic women with twin pregnancies and cervical length less than 38 mm were randomized to Arabin pessary or vaginal progesterone (400 mg once a day) group. The primary outcome was preterm birth at less than 34 weeks of gestation. Secondary outcomes were adverse maternal and perinatal complications. We planned a subgroup analysis according to quartile of cervical length. Analysis was conducted on an intention-to-treat basis. We estimated that the primary outcome would occur in 28.4% of women treated with progesterone. Thus a total sample size of 290 women divided equally into two groups was required to detect a 14% absolute risk difference in the primary outcome between the two groups (power 80%, alpha-error 5%, 10% loss to follow-up). RESULTS: Between March 2016 and June 2017, we randomized 300 women, 150 women in each group. Preterm birth at less than 34 weeks of gestation occurred in 24 (16%) women in the pessary group and 33 (22%) women in the progesterone group (relative risk [RR] 0.73, 95% CI 0.46-1.18). The use of pessary significantly reduced the composite of poor perinatal outcomes (19% vs 27%; RR 0.70, 95% CI 0.43-0.93). In women with cervical length of 28 mm or less (25th percentile), pessary significantly reduced the preterm birth rate at less than 34 weeks of gestation from 46% (16/35) to 21% (10/47) (RR 0.47, 95% CI 0.24-0.90) and significantly improved the composite of poor perinatal outcomes. CONCLUSION: Cervical pessary and 400 mg vaginal progesterone resulted in similar rates of preterm birth at less than 34 weeks of gestation in women with twin pregnancies and cervical length less than 38 mm.

BACKGROUND: Appendicitis is the most common operative disease in children, yet few data exist to support specialized care for childhood appendicitis. We hypothesized that children treated with specialized care are younger, have more severe disease, and experience equal or better outcomes. METHODS: Texas Blue Cross/Blue Shield claims data were reviewed for all children <18 years who underwent appendectomy for acute appendicitis from 2008 to 2012. Primary outcomes included adverse events, 30-day readmissions, and hospital duration of stay. χ(2), Fisher exact test, Student t test, and multivariate regression were performed. RESULTS: Of the 3,886 pediatric appendectomies, 894 (23%) were performed by pediatric surgeons and 1,558 (40%) were performed in children's hospitals. Children treated by pediatric surgeons were younger, had more severe disease, underwent fewer computed tomography (CT) examinations, and were hospitalized longer (all P < .05). Similarly, children treated in children's hospitals were younger, underwent fewer CTs, were more likely to undergo laparoscopic appendectomy, and were hospitalized longer (all P < .05). Specialized care did not predict adverse events or 30-day readmissions; however, specialized care was associated with longer duration of stay (P < .01). CONCLUSION: Privately insured children in Texas treated for appendicitis by pediatric surgeons or in children's hospitals were younger, had more severe disease, and were hospitalized longer but were less likely to undergo preoperative CT.
