Vaccine hesitancy and COVID-19 immunization among rural young adults.

Rural young adults may be more averse to receiving a COVID-19 immunization than urban young adults. We aimed to assess differences in COVID-19 vaccine hesitancy for rural, compared with urban, young adults and characterize modifiable factors. This cross-sectional online survey collected demographic data, vaccination attitudes, and COVID-19 impacts from 2937 young adults, ages 18-26 years, across the western U.S. from October 2020 to April 2021. Rurality was determined by participants' zip code and classified using the rural and urban continuum codes (RUCC). Multivariable logistic regression described adjusted (age, gender, race and ethnicity, being a current student, and month of survey) odds of self-reported intent to receive the COVID-19 vaccination by rurality. Mediation analysis was used to decompose total effects into average direct effects and average causal mediation (indirect) effects. Rural participants had 40% lower odds than urban participants of intending to receive the COVID-19 vaccine after adjustments (adjusted odds ratio, 0.62 [95% CI, 0.50-0.76]). The direct effect remained (P < 0.001), but was mediated by both education (8.3%, P < 0.001) and month in which the survey was taken (23.5%, P < 0.001). We observed a divergence after December 2020 in vaccination intent between rural and urban young adults that widened over time. Hesitancy to receive the COVID-19 vaccine was greater among rural, compared with urban young adults, and grew disproportionally after December 2020. Mediation by whether one was a current student or not suggests differences in sources of information for vaccination decision-making, and highlights areas for addressing vaccine hesitancy.

Performance and Kinematic Differences Between Terrestrial and Aquatic Running in Anolis Sagrei.

Many animals frequently transition between different media while navigating their heterogeneous environments. These media vary in compliance, moisture content, and other characteristics that affect their physical properties. As a result, animals may need to alter their kinematics to adapt to potential changes in media while maintaining performance during predator escape and foraging. Due to its fluid nature, water is highly compliant, and although usually associated with swimming, water running has evolved in a variety of animals ranging from insects to mammals. While the best studied large water runners are the bipedal basilisk lizards (Basiliscus spp.), other lizards have also been observed to run across the surface of water, namely, Hemidactylus platyurus, a house gecko, and in this study, Anolis sagrei, the brown anole. Unlike the basilisk lizard, the primarily arboreal Anolis sagrei is not adapted for water running. Moreover, water running in A. sagrei, similar to that of the house gecko, was primarily quadrupedal. Here, we tested for performance and kinematic differences between aquatic and terrestrial running and if the variance in performance and kinematic variables differed between the two media. We found no difference in average and maximum velocity between running on land and water. We also found that Anolis sagrei had higher hindlimb stride frequencies, decreased duty factor, and shorter stride lengths on water, as well as more erect postures. Finally, we found that most kinematics did not differ in variance between the two media, but of those that were different, almost all were more variable during terrestrial running. Our findings show that animals may be capable of specialized modes of locomotion, even if they are not obviously adapted for them, and that they may do this by modulating their kinematics to facilitate locomotion through novel environments.

Successful Multi-Level HPV Vaccination Intervention at a Rural Healthcare Center in the Era of COVID-19.

Objectives: To develop and test a human papillomavirus (HPV) vaccination intervention that includes healthcare team training activities and patient reminders to reduce missed opportunities and improves the rate of appointment scheduling for HPV vaccination in a rural medical clinic in the United States. Methods: The multi-level and multi-component intervention included healthcare team training activities and the distribution of patient education materials along with technology-based patient HPV vaccination reminders for parents/caregivers and young adult patients. Missed vaccination opportunities were assessed pre- and post-intervention (n = 402 and n = 99, respectively) by retrospective chart review and compared using Pearson χ2. The patient parent/caregiver and young adult patient population (n = 80) was surveyed following the reminder messages and penalized logistic regression quantified unadjusted odds of scheduling a visit. Results: Missed opportunities for HPV vaccination declined significantly from the pre-intervention to the post-intervention period (21.6 vs. 8.1%, respectively, p = 0.002). Participants who recalled receipt of a vaccination reminder had 7.0 (95% CI 2.4-22.8) times higher unadjusted odds of scheduling a visit compared with those who did not recall receiving a reminder. The unadjusted odds of confirming that they had scheduled or were intending to schedule a follow-up appointment to receive the HPV vaccine was 4.9 (95% CI 1.51-20.59) times greater among those who had not received the vaccine for themselves or for their child. Conclusions: Results from this intervention are promising and suggest that vaccination interventions consisting of provider and support staff education and parent/caregiver and patient education materials, and reminders can reduce missed opportunities for vaccinations in rural settings.

Patient-reported opioid use for tissue expander-based breast reconstruction.

INTRODUCTION: There is limited evidence for appropriate post-operative opioid prescribing in breast reconstruction patients. We sought to describe postoperative outpatient prescription opioid use patterns (quantity and duration) following discharge after immediate breast reconstruction with tissue expanders (TE) and to identify demographic and/or clinical risk factors associated with postoperative outpatient opioid use. METHODS: Patients 18 years and older undergoing immediate TE-based breast reconstruction were given a 28-day postoperative pain medication log book. Descriptive statistics were performed to describe the quantity and duration of opioid use. Preoperative, intraoperative, and postoperative characteristics were examined and tested for their associations with postoperative opioid use. RESULTS: A total of 45 logbooks were completed. On average, patients used opioids for 7.42 days (SD = 6.45) after discharge home and used 15.9 (SD = 18.71) oxycodone 5 mg tablet equivalents (119.3 morphine milligram equivalents, SD = 140.31). The total number of oxycodone 5 mg equivalents consumed prior to discharge was associated with the amount of post-discharge opioid consumption (IRR=1.08, p<0.01). Each additional year of age was associated with a reduction in the days-to-opioid cessation by a factor of 0.97 (p=0.01). Each additional oxycodone 5mg equivalent consumed prior to hospital discharge was associated with an increase in the days-to-cessation after discharge by a factor of 1.04 (p=0.026). CONCLUSIONS: These patient-reported data will provide a benchmark which plastic surgeons can use to minimize narcotic use in patients and will help prevent issues of dependence, misuse, and diversion, while being mindful of adequate pain control. For patients discharging home after a one-night stay for immediate TE breast reconstruction, we recommend a prescription for 10 oxycodone 5 mg tablets, or 15 tablets if they are less than age 49 or have had high inpatient opioid use. Patients should also be counseled that the expected duration of outpatient opioid use is 7-11 days, and that 20 % of patients did not use any opioids following hospital discharge, making nonnarcotic pain regimens a real possibility.

Comparison of International Classification of Diseases and Related Health Problems, Tenth Revision Codes With Electronic Medical Records Among Patients With Symptoms of Coronavirus Disease 2019.

Importance: International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) codes are used to characterize coronavirus disease 2019 (COVID-19)-related symptoms. Their accuracy is unknown, which could affect downstream analyses. Objective: To compare the performance of fever-, cough-, and dyspnea-specific ICD-10 codes with medical record review among patients tested for COVID-19. Design, Setting, and Participants: This cohort study included patients who underwent quantitative reverse transcriptase-polymerase chain reaction testing for severe acute respiratory syndrome coronavirus 2 at University of Utah Health from March 10 to April 6, 2020. Data analysis was performed in April 2020. Main Outcomes and Measures: The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of ICD-10 codes for fever (R50*), cough (R05*), and dyspnea (R06.0*) were compared with manual medical record review. Performance was calculated overall and stratified by COVID-19 test result, sex, age group (<50, 50-64, and >64 years), and inpatient status. Bootstrapping was used to generate 95% CIs, and Pearson χ2 tests were used to compare different subgroups. Results: Among 2201 patients tested for COVD-19, the mean (SD) age was 42 (17) years; 1201 (55%) were female, 1569 (71%) were White, and 282 (13%) were Hispanic or Latino. The prevalence of fever was 66% (1444 patients), that of cough was 88% (1930 patients), and that of dyspnea was 64% (1399 patients). For fever, the sensitivity of ICD-10 codes was 0.26 (95% CI, 0.24-0.29), specificity was 0.98 (95% CI, 0.96-0.99), PPV was 0.96 (95% CI, 0.93-0.97), and NPV was 0.41 (95% CI, 0.39-0.43). For cough, the sensitivity of ICD-10 codes was 0.44 (95% CI, 0.42-0.46), specificity was 0.88 (95% CI, 0.84-0.92), PPV was 0.96 (95% CI, 0.95-0.97), and NPV was 0.18 (95% CI, 0.16-0.20). For dyspnea, the sensitivity of ICD-10 codes was 0.24 (95% CI, 0.22-0.26), specificity was 0.97 (95% CI, 0.96-0.98), PPV was 0.93 (95% CI, 0.90-0.96), and NPV was 0.42 (95% CI, 0.40-0.44). ICD-10 code performance was better for inpatients than for outpatients for fever (χ2 = 41.30; P < .001) and dyspnea (χ2 = 14.25; P = .003) but not for cough (χ2 = 5.13; P = .16). Conclusions and Relevance: These findings suggest that ICD-10 codes lack sensitivity and have poor NPV for symptoms associated with COVID-19. This inaccuracy has implications for any downstream data model, scientific discovery, or surveillance that relies on these codes.

Convergent Evolution of Elongate Forms in Craniates and of Locomotion in Elongate Squamate Reptiles.

Synopsis Elongate, snake- or eel-like, body forms have evolved convergently many times in most major lineages of vertebrates. Despite studies of various clades with elongate species, we still lack an understanding of their evolutionary dynamics and distribution on the vertebrate tree of life. We also do not know whether this convergence in body form coincides with convergence at other biological levels. Here, we present the first craniate-wide analysis of how many times elongate body forms have evolved, as well as rates of its evolution and reversion to a non-elongate form. We then focus on five convergently elongate squamate species and test if they converged in vertebral number and shape, as well as their locomotor performance and kinematics. We compared each elongate species to closely related quadrupedal species and determined whether the direction of vertebral or locomotor change matched in each case. The five lineages examined are obscure species from remote locations, providing a valuable glimpse into their biology. They are the skink lizards Brachymeles lukbani, Lerista praepedita, and Isopachys anguinoides, the basal squamate Dibamus novaeguineae, and the basal snake Malayotyphlops cf. ruficaudus. Our results support convergence among these species in the number of trunk and caudal vertebrae, but not vertebral shape. We also find that the elongate species are relatively slower than their limbed counterparts and move with lower frequency and higher amplitude body undulations, with the exception of Isopachys. This is among the first evidence of locomotor convergence across distantly related, elongate species.

The general practitioner-patient consultation pattern as a tool for cancer diagnosis in general practice.

A case-control study design was used to examine consultation patterns during the three years leading up to the diagnosis of an internal malignancy, within the context of the registered patient list of a single large general practice at Winterton, North Lincolnshire. Using a combination of matching, consultation subclassification, and conditional logistic regression, account was taken of the major confounders affecting consultation rates. Generally, the odds of cancer rose in tandem with increases in the average time between new consultations. This trend was significant for all breast cancers (at the 5% level) and persisted after adjustment for occupation, smoking, and marital status (P = 0.03), as well as after the exclusion of patients identified by routine screening (P = 0.05).

Patients with new onset haematuria: assessing the discriminant value of clinical information in relation to urological malignancies.

BACKGROUND: There is little information available to assist general practitioners (GPs) in deciding which patients with haematuria are likely to have a malignancy. AIM: To derive discriminant functions for specific items or clusters of clinical history information in relation to the categorisation of patients presenting to the 'open access' haematuria clinic in Hull. DESIGN OF STUDY: Recruitment of patients via an 'open-access' haematuria clinic. SETTING: A consecutive series of 363 patients aged between 18 and 80 years who attended the clinic. METHOD: Between February 1999 and October 1999 clinical history information derived from the participating patients was compared with the patients' diagnoses. Diagnoses were established by a combination of cystoscopy and radiological assessments and rechecked against the patient records and the hospital patient administration system two to three months later. RESULTS: A number of individual variables seemed to be particularly helpful in discriminating malignancies. However, when indicants were combined using regression shrinkage techniques, only the following variables were preserved: age, sex, type of haematuria, number of episodes of haematuria, hesitancy, poor urinary stream, smoking history, and history of urinary tract infections. CONCLUSION: It is possible to generate helpful discriminant information to assist GPs in making more appropriate decisions in a difficult area of clinical practice. However, it remains a matter of judgement as to how representative the study population is likely to be compared with all haematuria patients encountered in primary care. We have reasonable confidence in the general applicability of the rules for macroscopic haematuria: however, it seems likely that the prediction rules outlined for microscopic haematuria have their greatest relevance once a patient has been referred by a GP. In developing the work further and testing out the discriminators identified in this study, we propose that a primary care-based project now needs to be undertaken focusing on microscopic haematuria with a particular emphasis on addressing selection biases. In addition, there is a more general need to assess the reliability of all the suggested items of clinical discriminant information.
