ABSTRACT

BACKGROUND: Internet search volume reflects the level of Internet users’ risk perception during public health events. The Internet search volume index model, an algorithm of concentration of Internet users, and statistical analysis of popular topics on Weibo are used to analyze the effects of time, space, and space-time interaction. We conducted in-depth research on the characteristics of the spatial and temporal distribution of Internet users’ risk perceptions of public health events and the associated influential factors.

METHODS: We analyzed the spatiotemporal distribution characteristics of Internet users’ risk perception after the Wuhan “city closing” order during the coronavirus disease 2019 (COVID-19) pandemic. We established five linear regression models according to different time periods and analyzed factors influencing Internet users’ risk perception by employing a Poisson and spatial distribution and topic modeling analysis.

RESULTS: Economy, education, health, and the degree of information disclosure affect Internet users’ risk perception significantly. Internet users’ risk perception conforms to the exponential distribution law in time and has periodic characteristics and stability trends. Additionally, Internet users’ average arrival rate dropped from week 1 to week 8 after the “city closing.” Internet users’ risk perception has a uniform distribution in space, economic and social development level distribution consistency, spatial agglomeration, and other characteristics. The results of the time-space interaction show that after 8 weeks of COVID-19, Internet search hot topics have become more stable, and Internet users’ information demand structure has become more rational.

CONCLUSIONS: The Internet search cycle of the COVID-19 event is synchronized with the evolution cycle of the epidemic. The physical risk of Internet users is at the top of the risk structure, focusing on the strong concern about the government’s ability to control COVID-19 and its future trend. The government should strengthen network management; seize the risk control focus of key time nodes, regional locations, and information content of online communication; actively adjust the information content supply; effectively control the rebound of Internet users’ risk perception; establish a data-driven, risk-aware intelligence system for internet users; and guide people to actively face and overcome the potential risks and threats of COVID-19.

ABSTRACT

BACKGROUND: “Double eyelid” blepharoplasty is one of the most common cosmetic operations among Asian populations. Some patients might present with concomitant mild to moderate blepharoptosis, even though they choose initially to undergo blepharoplasty for cosmetic reasons.

OBJECTIVE: Using nonincisional double eyelid surgery without ptosis correction tends to produce unsatisfactory results. We introduce our modified suture method for the simultaneous correction of blepharoptosis during double eyelid blepharoplasty.

MATERIALS AND METHODS: We carried out a retrospective review on 13 patients who underwent simultaneous nonincisional ptosis correction and double eyelid surgery, using a single-knot continuous technique, from January 2017 to December 2019. A superior tarsal (Müller’s) muscle tagging suture was utilized to achieve an accurate tucking during surgery and create a double upper lid fold simultaneously.

RESULTS: The mean patient age was 31.8 years (range=23-54), and 9 patients (69%) were female. The mean marginal reflex distance 1 increased from 2.46±0.36 mm preoperatively to 4.07±0.61 mm postoperatively with a statistically significant difference. Most patients showed favorable results with an average of 10.8 months of follow-up and minimal complications.

CONCLUSIONS: This simultaneous double eyelid blepharoplasty technique using a single-knot, continuous, nonincisional technique is relatively easy and effective, with minimal downtime and few postoperative complications, and avoids scarring for patients with mild to moderate blepharoptosis.

ABSTRACT

INTRODUCTION: The COVID-19 pandemic has caused many residency programs to pivot from traditional face-to-face to virtual teaching. The objective of this study was to assess the state of virtual education in Canadian urology programs and gauge interest in a national virtual curriculum.

METHODS: An electronic 15-item survey was distributed to all 13 Canadian urology programs’ directors and administrative assistants for circulation to residents. Data collection took place over six weeks from September to November 2020. A mixed-methods approach was used, including descriptive statistics and an inductive thematic analysis of responses to open-ended questions.

RESULTS: Eleven program directors and 32 residents from all four geographic areas (Atlantic, Ontario, Quebec, Western [MB, AB, BC]) responded to the survey. Overall, 95.3% of respondents indicated a role for virtual education in their program during the pandemic. Most respondents (74.4%) believe there is a significant or very significant role for a virtual national urology curriculum. All program directors indicated they are at least somewhat likely to require resident participation in such a curriculum. Most (90.6%) resident respondents indicated they believe such a curriculum will be at least somewhat important to their learning. Commonly described benefits include exposure to subspecialties, expertise at other institutions, and standardization of teaching. Commonly described barriers include difficulty with engagement, time zone differences, and lack of dedicated time for attendance.

CONCLUSIONS: During the COVID-19 pandemic, virtual education has become well-integrated in Canadian urology programs. This study highlights interest in the development of a national virtual urology curriculum and puts forth some key considerations to ensure its success.

ABSTRACT

OBJECTIVE: Cardiovascular disease is a major cause of morbidity and mortality in systemic lupus erythematosus (SLE). Hypertension (HTN) and nondipping are modifiable risk factors for cardiovascular disease. Limited studies are available for childhood-onset SLE (cSLE). We aimed to assess ambulatory blood pressure monitoring (ABPM) pattern in cSLE patients with normal office blood pressure.

METHODS: This cross-sectional single-center study enrolled 25 patients with cSLE, normal office blood pressure and normal renal function. We performed 24-hour ABPM and echocardiography to assess end-organ damage. Descriptive statistics were obtained, and comparison of variables using Fisher exact test, t test, and Mann-Whitney U test was performed to identify potential risk factors for nondipping.

RESULTS: Of the 25 patients, 22 were women; the median age was 18 years (interquartile range, 16-20 years). Median SLE duration was 4.2 years (interquartile range, 2.9-8.1 years); 18 patients had a history of lupus nephritis (LN). Four patients, 3 of whom had LN, had masked HTN. Fourteen patients (56%) were nondipping. The majority of patients without LN (71%) had a nondipping profile. Echocardiography was done for 15 patients. Left ventricular mass index, relative wall thickness, and ejection fraction were normal in all patients. Ambulatory blood pressure monitoring results led to changes in therapy in 5 patients.

CONCLUSION: Our data provide evidence of high prevalence of nondipping and masked HTN in patients with cSLE, even in patients without LN. Identifying ABPM abnormalities in these patients could potentially improve outcomes.

ABSTRACT

CONTEXT: Although chronic pain and high-risk alcohol use are prevalent in primary care and associated with more severe pain and functional impairment, current approaches address them separately and often neglect risky alcohol use among those with chronic pain. Treatments tailored to patient preferences increase utilization, yet little is known about patient treatment preferences for chronic pain and high-risk alcohol use.

OBJECTIVE: Describe treatment barriers and preferences of primary care patients with chronic musculoskeletal pain and past-year alcohol use and test for differences based on alcohol use (no risk, low risk, high risk).

STUDY DESIGN: Chart review and patient survey.

SETTING: VA primary care clinics. Inclusion criteria: ≥ 18 years old, past year VA primary care visit, chronic musculoskeletal condition, past year alcohol use. Exclusion criteria: psychotic or neurocognitive disorder diagnosis. Eligible participants were identified via chart review and mailed a survey packet.

POPULATION STUDIED: Participants (N = 371) were primarily White (74.7%) male (88.4%) veterans.

MAIN AND SECONDARY OUTCOME MEASURES: Readiness to change, alcohol treatment barriers, pain-alcohol beliefs, attitudes toward behavioral health and medical treatment, and treatment preferences were assessed.

RESULTS: Chi-square tests revealed statistically significant preferences for: face-to-face (70.3% preferred), individual (68.7% preferred), VA primary care, (69.2% preferred), and chronic pain focus (38.4% preferred). Patients with high-risk alcohol use reported more readiness to change alcohol use, stronger pain-alcohol beliefs, and more favorable attitudes toward behavioral health treatment than those with low- or no-risk alcohol use.

CONCLUSIONS: Primary care patients with chronic musculoskeletal pain and alcohol use showed clear preferences for individual, face-to-face behavioral health treatment focused on chronic pain in a VA primary care clinic. Those with co-occurring high-risk alcohol use may experience differences in treatment barriers that may impede treatment engagement (i.e., stronger pain-alcohol beliefs), and in other cases, may facilitate treatment engagement (i.e., more readiness to change, more favorable treatment attitudes) compared to those with low- or no-risk alcohol use. Incorporating patient perspectives may help clinicians provide optimal behavioral health treatment for chronic pain and/or hazardous alcohol use in primary care.

ABSTRACT

CONTEXT: Primary care providers can ask men about intimate partner violence (IPV) perpetration or victimization using validated questions, yet physicians feel unprepared to screen men for IPV. Few studies examine men’s physical IPV categories of perpetration-only, both perpetration and victimization, and victimization-only, or their associations with technology-facilitated abuse (TFA).

OBJECTIVE: Assess (1) prevalence of men’s physical IPV and (2) associations of physical IPV with demographics, children, health services use, self-reported physical or mental health diagnoses, substance use problems, and TFA.

STUDY DESIGN: Survey with survey-weighted descriptive statistics and multinomial logistic regression.

SETTING: Community-based nationally representative sample of U.S. men using IPSOS KnowledgePanel August-September 2014.

POPULATION STUDIED: 2,889 men age 18-35 with response rate 47% (1346/2889). Inclusion criteria “ever in a romantic relationship” yielded analysis sample 1074 men.

OUTCOME MEASURE: Physical IPV categories: perpetration-only, both perpetration and victimization, and victimization-only.

RESULTS: Among young U.S. men, physical IPV was reported by 2.5% perpetration only, 16.7% both perpetration and victimization, and 10.0% victimization only. Multivariate analyses showed physical IPV perpetration-only associated with primary care use (AOR 0.25, 95%CI 0.09-0.70), chronic pain (AOR 6.92, 95%CI 1.74-27.55), and prescription opioid misuse (AOR 2.31, 95%CI 1.53-3.47); IPV both perpetration and victimization associated with belief that children who do not witness parental IPV are still harmed (AOR 0.59, 95%CI 0.43-0.82), primary care use (AOR 0.54, 95%CI 0.31-0.94), alcohol misuse (AOR 1.08, 95%CI 1.01-1.15), prescription opioid misuse (AOR 1.58, 95%CI 1.09-2.29), TFA delivered only (AOR 3.64, 95%CI 1.23-10.80), TFA both delivered and received (AOR 6.08, 95%CI 3.32-11.13), TFA received only (AOR 4.95, 95%CI 1.54-15.91); IPV victimization-only associated with mental healthcare visits (AOR 2.34, 95%CI 1.19-4.64), TFA both delivered and received (AOR 2.31, 95%CI 1.16-4.58), and TFA received only (AOR 5.26, 95%CI 2.24-12.38).

CONCLUSIONS: Among young U.S. men, physical IPV was reported by 1 in 40 for perpetration only, 1 in 6 for both perpetration and victimization, and 1 in 10 for victimization only. Primary care physicians can consider assessing physical IPV among male patients. Limitations include self-report and no context for IPV.

ABSTRACT

BACKGROUND: Risk-reducing mastectomy is one option for women with hereditary breast and ovarian cancer to reduce the risk of breast cancer.

PATIENTS AND METHODS: We analyzed data of the Japanese Organization of Hereditary Breast and Ovarian Cancer on women who were diagnosed as hereditary breast and ovarian cancer by BRCA germline genetic testing between 2010 and 2019 to reveal the rate and likelihood of risk-reducing mastectomy.

RESULTS: There were 412 women with BRCA1, 271 with BRCA2 and 4 with both female pathogenic variants. Ninety (13.1%) received risk-reducing mastectomy. The rates of risk-reducing mastectomy were statistically significantly higher in women with BRCA1 pathogenic variants than BRCA2, in women who had breast cancer than those who did not, in women with a breast cancer family history than in those without, in mothers than in those without children, in women who were receiving surveillance with MRI than those who were not and in women who received risk-reducing salpingo-oophorectomy than in those who did not on univariate analyses. The ages when they received the genetic testing were statistically significantly younger in the women receiving risk-reducing mastectomy than those who did not receive it. The women with BRCA1 pathogenic variants, personal history of breast cancer, mothers, those receiving MRI surveillance and younger women were independently significantly more likely to receive risk-reducing mastectomy based on multivariate analysis.

CONCLUSIONS: The rate of risk-reducing mastectomy was not high in Japan; however, risk-reducing surgery was approved by the Japanese National Medical Insurance for hereditary breast and ovarian cancer patients with breast and/or ovarian cancer in 2020, so this rate will increase.

ABSTRACT

Tandem mass spectrometry (MS/MS) is a primary tool for the identification of small molecules and metabolites where resultant spectra are most commonly identified by matching them with spectra in MS/MS reference libraries. The high degree of variability in MS/MS spectrum acquisition techniques and parameters creates a significant challenge for building standardized reference libraries. Here we present a method to improve the usefulness of existing MS/MS libraries by augmenting available experimental spectra data sets with statistically interpolated spectra at unreported collision energies. We find that highly accurate spectral approximations can be interpolated from as few as three experimental spectra and that the interpolated spectra will be consistent with true spectra gathered from the same instrument as the experimental spectra. Supplementing existing spectral databases with interpolated spectra yields consistent improvements to identification accuracy on a range of instruments and precursor types. Applying this method yields significant improvements (∼10% more spectra correctly identified) on large data sets (2000-10 000 spectra), indicating this is a quick yet adept tool for improving spectral matching in situations where available reference libraries are not yet sufficient. We also find improvements of matching spectra across instrument types (between an Agilent Q-TOF and an Orbitrap Elite), at high collision energies (50-90 eV), and with smaller data sets available through MassBank.

ABSTRACT

A new efficient method for calculating the enthalpies of salt formation is proposed. The method is based on a fundamentally new cocrystal model, consisting of a mixture of cations and anions and a “quasi-salt” of neutral components, in fact, of the salt itself, and the enthalpy of formation is calculated as the average value between the enthalpies of formation of these two structural components. Unlike correlation and additive schemes, this method is based on the construction of a real physical model of a salt crystal, for which the molecular geometry of the ions and neutral salt components is preliminarily optimized by quantum chemistry methods. Further, based on the obtained data, the initial models of crystal lattices in the statistically most probable structural classes are constructed with their subsequent optimization by the method of Atom-Atom potentials. For a number of compounds of various chemical classes, the effectiveness of the method for estimating the enthalpy of salts is shown, which surpasses the known methods in terms of calculation accuracy.

ABSTRACT

BACKGROUND: Critical care nurses experience moral distress, the phenomenon of knowing the “right” thing to do but being unable to do so, at high rates; this contributes to attrition and has severe mental health impacts on nurses.

OBJECTIVE: The purpose of this integrative review was to determine if interventions to reduce moral distress have an effect on intensive care unit (ICU) nurses’ moral distress levels.

METHODS: Three databases were searched, PubMed, APA PsycNet, and CINAHL, using the keywords “moral distress” AND nurs* AND reduc* AND (“intensive care” OR “critical care” OR ICU). Only experimental studies involving adult ICU nurses were included for a total of 6 studies.

RESULTS: Interventions fell into 3 categories: (1) educational interventions, (2) interventions to enhance the ICU environment, and (3) interventions to help nurses cope. Two studies detailing educational interventions demonstrated some reduction in moral distress. One study aimed to improve the ICU environment and showed some statistically significant reduction in moral distress. All 6 studies included some focus on coping, and 2 showed statistically significant reductions in moral distress.

DISCUSSION: Only a few studies have been conducted examining this issue. These studies had severe limitations, such as small sample sizes, attrition, and inadequate control groups. There were also few statistically significant results. These interventions should be reexamined using larger sample sizes, and other interventions should also be trialed. COVID-19 may have had a significant impact on this issue, and interventions may need to be refocused in the wake of the pandemic.
