RESUMO

High-resolution esophageal manometry (HREM) is a fundamental diagnostic tool in esophagology. Educational tools for this procedure have remained scarce. This quality improvement project aimed to develop an enhanced digital recording about HREM and assess the effect on patient knowledge, anxiety, satisfaction, and procedure abortion rates. The Institute for Healthcare Improvement Model for Improvement and the self-regulation theory guided this project. An interprofessional team was formed. A video recording of the pre-, peri-, and post-HREM care was created. Participants were recruited in the following four cycles: Baseline, Workstation, Manometry, and Home. Questionnaires were collected pre- and postvideo education. The results demonstrated a significant increase in knowledge from 60% to 96% ( p < .001), 58% to 96% ( p < .001), 79% to 96% ( p < .001), and 92% to 97% ( p = .02) and reductions in anxiety from 7.1 to 5.5 ( p = .003), 7.6 to 6.1 ( p = .003), 7.1 to 6.5 ( p < .001), and 6.4 to 6.1 ( p = .03) in all four groups. Almost all (99.5%) participants liked the recorded education and only 2.6% of cases were aborted during the 1-year project implementation period from June 2020 to May 2021. Findings from this project support the positive impact of recorded patient education. An educational recording is standardized and has the potential to be implemented in variable settings.

RESUMO

BACKGROUND: Despite neck pain being a common complaint for people with migraine, little is known about how individuals perceive the relationship between their migraine and neck pain. Exploring their beliefs and perceptions could provide valuable understanding to improve overall management and reduce the burden of migraine and neck pain. OBJECTIVES: To investigate individual perspectives on how migraine and neck pain relate. METHODS: A retrospective qualitative study was performed. Seventy participants (mean age 39.2, 60 female) were recruited via community and social media advertisements, and interviewed by an experienced physiotherapist using a semi-structured interview framework. An Inductive thematic analysis was used to analyse the responses. RESULTS: Five themes were identified from the interviews: (i) the timing of neck pain and migraine, (ii) causality beliefs, (iii) burden of neck pain and migraine, (iv) experiences with treatment and (v) mismatched perspectives. Diverse views emerged, revealing links between the first two themes of timing and causality, showing increased burden in those suffering from both neck pain and migraine, and providing insights into apparently ineffective or even aggravating treatments. CONCLUSIONS: Valuable insights for clinicians emerged. Due to the complex relationship, clinicians should discuss the aetiology of neck pain in migraine with patients. For some individuals, neck treatment may not produce long-term relief and may even aggravate migraine, but the value of short-term relief in a chronic condition must be considered individually. Clinicians are ideally placed to have discussions with patients individually to tailor individual decisions about management.

RESUMO

In miniaturized electronic and optoelectronic circuits, molecular tunnel junctions have attracted enormous research interest due to their small footprint, low power consumption, and rich molecular functions. However, the most popular building blocks used in contemporary molecular tunnel junctions are thiol molecules, which attach to electrode surfaces via a metal-thiolate (MS) bond, showing low stability and usually quick degradation within several days. To pave the way for more widely applicable and stable molecular tunnel junctions, there is a need to develop new molecular anchoring groups. Here, this work demonstrates robust and air-stable molecular tunnel junctions with a sub-5 nanometer bis(diarylcarbene)-based thin film as the tunneling barrier, which anchors to the electrode surface via a AuC bond. The bis(diarylcarbene)-based molecular tunnel junctions exhibit high thermal stability against heating up to 200 °C and long storage lifetime over 5 months in an ambient environment. Both electrical and optical performance of these bis(diarylcarbene)-based molecular junctions are characterized systematically, showing similar behaviors to thiol-based junctions as well as largely improved emission stability. This research highlights the excellent performance of bis(diarylcarbene)-based molecular tunnel junctions, which could be useful for applications in molecular electronics and plasmonics.

RESUMO

BACKGROUND: Korean immigrants are among the fastest-growing ethnic minority groups and make up the fifth-largest Asian group in the United States. A better understanding of the work environment factors and its impact on Korean American nurse and primary care provider (PCP) burnout may guide the development of targeted strategies to help mitigate burnout and workplace stressors, which is critical for the retention of Korean American nurses and PCPs to promote better alignment of national demographic trends and meet patients' preference for cultural congruence with their health care providers (HCPs). Although there is a growing number of studies on HCP burnout, a limited number of studies specifically focus on the experience of ethnic minority HCPs, particularly during the COVID-19 pandemic. OBJECTIVE: In light of these gaps in literature, the aim of this study was to assess burnout among Korean American HCPs and to identify work conditions during a pandemic that may be associated with Korean American nurse and PCP burnout. METHODS: A total of 184 Korean American HCPs (registered nurses [RNs]: n=97; PCPs: n=87) practicing in Southern California responded to a web-based survey between February and April 2021. The Maslach Burnout Inventory, Areas of Worklife Survey, and Pandemic Experience & Perceptions Survey were used to measure burnout and work environment factors during the pandemic. A multivariate linear regression analysis was used to assess work environment factors associated with the 3 subcategories of burnout. RESULTS: No significant differences were found in the level of burnout experienced by Korean American nurses and PCPs. For RNs, greater workload (P<.001), lower resource availability (P=.04), and higher risk perception (P=.02) were associated with higher emotional exhaustion. Greater workload was also associated with higher depersonalization (P=.003), whereas a greater (professional) community (P=.03) and higher risk perception (P=.006) were associated with higher personal accomplishment. For PCPs, greater workload and poor work-life balance were associated with higher emotional exhaustion (workload: P<.001; worklife: P=.005) and depersonalization (workload: P=.01; worklife: P<.001), whereas only reward was associated with personal accomplishment (P=.006). CONCLUSIONS: Findings from this study underscore the importance of strategies to promote a healthy work environment across multiple levels that recognize demographic variation among Korean American RNs and PCPs, potentially influencing their burnout mitigation needs. A growing recognition of identity-informed burnout experiences across frontline Korean American RNs and PCPs argues for future explorations that capture nuance both across and within this and other ethnic minority nurse and PCP groups. By recognizing and capturing these variations, we may better support the creation of targeted, burnout-mitigating strategies for all.

RESUMO

OBJECTIVES: Although carotid artery intima media thickness (CIMT) is a widely used determinant of subclinical atherosclerosis, gray-scale median of the intima-media complex (IM-GSM) of the common carotid artery is a relatively novel measure of echogenicity reflecting composition of the arterial wall. It is important to compare cardiovascular disease (CVD) risk factor correlates across CIMT and IM-GSM to determine whether these measures reflect distinct aspects of atherosclerosis. METHODS: Baseline information from a completed randomized clinical trial of 643 healthy postmenopausal women without clinically apparent CVD was included in this cross-sectional study. The women were on average ± SD 61 ± 7 years old, and predominantly non-Hispanic White. CIMT and IM-GSM were measured by high-resolution B-mode ultrasonogram in the far wall of the right common carotid artery. CVD risk factors including age, race, body mass index (BMI), smoking, weekly hours of physical activity, systolic (SBP) and diastolic blood pressure (DBP), lipids, glucose, and inflammatory markers were measured at baseline. Linear regression models were used to assess associations of CVD risk factors with CIMT and IM-GSM. Multivariable models included groups of risk factors added one at a time with and withoutbasic demographic factors (age, race, BMI, physical activity) with model R2 values compared between CIMT and IM-GSM. RESULTS: In multivariable analysis, age, Black race, BMI, SBP, and DBP were associated with CIMT (all P < .05), whereas age, Hispanic race, BMI, SBP, physical activity, LDL-cholesterol, and leptin were correlates of IM-GSM (all P < .05). Adjusted for age, race, BMI, and physical activity, the R2 value for SBP was greater for CIMT association, whereas R2 values for lipids, glucose, inflammatory markers, and adipokines were greater for IM-GSM associations. CONCLUSIONS: CIMT and IM-GSM assess different attributes of subclinical atherosclerosis. Integrating both measures may provide improved assessment of atherosclerosis in asymptomatic individuals.

RESUMO

Two-dimensional semiconducting transition-metal dichalcogenides (TMDCs) have attracted extensive attention as building blocks of miniaturized electronic and optical devices. However, as the characteristics of TMDC devices are predominately determined by their device structures, the function of TMDC devices is fixed once fabricated, leaving the reconfigurable active device and circuit a challenge. Here, we have demonstrated the current rectification switching in TMDC vertical diodes using a liquid metal (EGaIn) top electrode with a reconfigurable contact area. The rectification switching is closely related to the ultrathin gallium oxide layer on the surface of EGaIn. Under the small contact, with the existence of gallium oxide, photocurrent dominates the electrical transport showing a negative rectification, while as the contact increases, the broken gallium oxide leads to rectification switching to the positive bias direction. Such rectification switching applies to thin TMDC flakes down to 3 nm, benefitting from the soft electrical contact between the TMDC and the EGaIn electrode. Our work shows the new possibility of actively reconfigurable TMDC vertical diodes enabled by the liquid metal electrode and will promote promising applications of flexible and tunable TMDC-based nanoelectronic devices.

RESUMO

Background: Syncope is the primary cause of transient loss of consciousness, which causes severe physical and mental burdens to children and adolescents. Objective: The study was designed to analyze the spectrum of underlying diseases of syncope and treatment options for neurally-mediated syncope (NMS) in Chinese children and adolescents. Methods: Medical records including history, physical examination, blood biochemistry, standing test, head-up tilt (HUTT), sitting-up test, electroencephalogram (EEG), electrocardiogram (ECG), and echocardiography were retrospectively studied in children and adolescents admitted to the National Pediatric Syncope Center, Department of Pediatrics, Peking University First Hospital between 1992 and 2021. All the data were collected from the Beijing Kaihua Medical Management System (Kaihua, Beijing, China). Children who met the syncope diagnostic criteria were enrolled in the study. The spectrum of the underlying diseases of syncope in children and adolescents and the treatment options of NMS were analyzed. Results: A total of 1,947 children and adolescents with syncope were admitted, including 869 males (44.63%) and 1,078 females (55.37%) aged 1-18 years, with an average age of 11.1 ± 3.1 years. The number of children and adolescents with syncope displayed a gradually increasing trend between 1992 and 2021 except after 2020. NMS proportion increased, and the proportion of unexplained syncope decreased (χ2 = 128.839, P < 0.01). The treatment options of NMS mainly included autonomic nervous function exercise (549, 34.46%), oral rehydration salt (ORS; 445, 27.94%), metoprolol (219, 13.75%), midodrine (120, 7.53%), ORS plus metoprolol (139, 8.73%), ORS plus midodrine (120, 7.53%), and pacemakers (1, 0.06%). Patients with vasovagal syncope (VVS) coexisting with postural orthostatic tachycardia syndrome (POTS) were more likely to take pharmacological treatments than those with VVS or POTS only (χ2 = 41.696, P < 0.01). Conclusion: The number of children with syncope displayed an increasing trend before 2020, and the proportion of unexplained syncope decreased. Autonomic nervous function exercise was the most common treatment for children and adolescents with NMS. Children with VVS coexisting with POTS were more likely to receive pharmacological treatments than those with either.

RESUMO

OBJECTIVE: To evaluate the effect of hormone therapy (HT) on arterial wall composition by ultrasound. BACKGROUND: The effect of HT on the progression of subclinical atherosclerosis has been well-described using measurements of common carotid artery (CCA) wall thickness. However, it is unknown whether the change in arterial wall anatomic structure is accompanied by an effect of HT on arterial wall composition. METHODS: A total of 643 healthy postmenopausal women divided into two strata according to the time since menopause (<6 years, the early-postmenopause group; or >10 years, the late-postmenopause group) were randomized to receive either active treatment or placebo. For hysterectomized women, the active treatment was oral micronized 17ß-estradiol 1 mg/day; for women with a uterus, 4% vaginal micronized progesterone gel 45 mg/day for 10 days each month was added to the estradiol regimen. Gray-scale median of the CCA intima-media complex (IM-GSM), a (unitless) measurement of arterial wall composition based on echogenicity, was determined by high-resolution B-mode ultrasonography. Lower IM-GSM, or less echogenicity, indicates more atherosclerosis. IM-GSM and serum estradiol (E2) concentration were assessed every 6 months over a median 4.8-year trial period. Linear mixed effects regression models were used for all analyses. RESULTS: Overall, IM-GSM progression/year had a negative trajectory, reflecting reduction in echogenicity over time (worsening atherosclerosis). HT effects on IM-GSM progression/year differed by postmenopause strata (interaction p-value = 0.02). IM-GSM progression/year (95% CI) in the early postmenopause group randomized to HT was -0.50 (-0.82, -0.18)/year compared with -1.47 (-1.81, -1.13)/year among those randomized to placebo (p-value <0.0001). In the late postmenopause group, the annual IM-GSM progression rate did not significantly differ between HT and placebo (p = 0.28). Higher mean on-trial E2 (pg/ml) levels were associated with higher IM-GSM progression, indicating less atherosclerosis progression in all women (ß (95% CI) = 0.006 (0.0003, 0.01), p = 0.04). For each pg/dl E2, IM-GSM progression/year was 0.007 ((-0.0002, 0.01), p = 0.056) in the early and 0.003 ((-0.006, 0.01), p = 0.50) in the late postmenopause group (interaction p-value = 0.51). CIMT progression rate (µm/year) was significantly inversely associated with the IM-GSM progression (ß (95% CI) = -4.63 (-5.6, -3.7), p < 0.001). CONCLUSIONS: HT, primarily with oral estradiol, reduced atherogenic progression of arterial wall composition in healthy postmenopausal women who were within 6 years from menopause. TRIAL REGISTRATION NUMBER: NCT01553084.

RESUMO

BACKGROUND: Prolonged exposure to work-related stress can lead to nurse burnout, potentiating clinical and medication errors and low-quality patient care. Holistic approaches (such as mindfulness training, "zen rooms," and massage chairs, among others) have been shown to reduce nurses' anxiety, stress, and burnout. PURPOSE: To evaluate the use of "serenity lounges" (dedicated rooms where nurses can take workday breaks for the purposes of relaxation and rejuvenation) and massage chairs on nurses' anxiety, stress, and burnout. METHODS: This quality improvement project analyzed 67 paired responses to surveys filled out by nurses before and after their use of serenity lounges at a medical center in Los Angeles between November 2020 and May 2021. Following successful implementation of a serenity lounge on a pilot unit, this project was expanded to a total of 10 units, including COVID-19 cohort units. As part of this expansion, massage chairs were added to 10 serenity lounges, along with items such as wipes, gloves, and shoe covers to enable nurses to adhere to infection control protocols. RESULTS: Analysis of the 67 paired responses to pre- and post-lounge-use surveys revealed a significant reduction in feelings of emotional exhaustion, burnout, frustration, being worn out, stress, and anxiety after use of the serenity lounge. Improvements in feelings of emotional exhaustion, being worn out, and being anxious were also noted after using the massage chair for at least 10 to 20 minutes. CONCLUSIONS: These results highlight the importance of providing a holistic approach, including a serene space, massage equipment, and other amenities, to help nurses reduce feelings of anxiety, stress, and burnout, particularly during challenging times such as the COVID-19 pandemic.

RESUMO

OBJECTIVES: To investigate the usefulness of neurite orientation dispersion and density imaging (NODDI) in evaluating cortical tubers, especially epileptogenic tubers in tuberous sclerosis complex (TSC) patients. METHODS: High-resolution conventional MRI and multi-shell diffusion-weighted imaging were performed in 27 TSC patients. Diffusion images were fitted to NODDI and DTI models. Tubers were visually assessed on different image types and scored by two neuroradiologists. For 10 patients who underwent epilepsy surgery, the contrast ratios between lesion and background tissue were measured on different image types, and these were compared between 16 epileptogenic tubers and 92 non-epileptogenic tubers. RESULTS: There were significant differences in lesion conspicuity scores and lesion-background contrast ratios across different sequences (both p < 0.001). The post hoc analysis showed that both the conspicuity scores and contrast ratios of intracellular volume fraction (ICVF) derived from NODDI were higher than other image types. For the 16 epileptogenic tubers, lesion visibility on ICVF was better/equal in 4/12 tubers compared with conventional MRI and better/equal in 5/11 tubers compared with DTI. Significant differences were observed between epileptogenic and non-epileptogenic tubers on diffusion maps, especially on orientation dispersion index derived from NODDI (p < 0.0001). CONCLUSIONS: ICVF demonstrated higher contrast than conventional MRI and DTI, which helped detection of subtle epileptogenic tubers. Moreover, NODDI parameters showed the potential to identify epileptogenicity. KEY POINTS: • The noninvasive localization of epileptogenic cortical tubers is essential for the preparation of epilepsy surgery for TSC patients. • ICVF derived from NODDI showed greater contrast than conventional MRI and DTI in detecting tubers, especially subtle epileptogenic ones. • Diffusion parameters, especially ODI derived from NODDI, can support the identification of epileptogenicity.

RESUMO

In this paper, we described 2 cases with COVID-19 pneumonia, who developed pulmonary emphysema, bullae, and pneumothorax during therapy. In a 48-year-old man with mechanical ventilation, parts of ground glass opacities and consolidations transformed into emphysema and giant bulla, and bilateral pneumothorax were also observed. In a 35-year-old man, localized emphysema and pulmonary bullae were seen in subpleural area in bilateral upper lobes, where no previous lesions were presented. In conclusion, pulmonary emphysema, bullae, and pneumothorax could be complications of COVID-19. On one hand, surgical emphysema in ventilated COVID-19 patients was observed as in SARS patients. On the other hand, more serious destruction of lung parenchyma was found in COVID-19 patients.

RESUMO

OBJECTIVES: The aim of this study is to investigate the relationship between spinal MRI findings with disease activity and other clinical and serological parameters, and to determine the importance of MRI scoring system in evaluating disease activity of SAPHO syndrome. METHODS: Thirty patients with SAPHO syndrome underwent clinical, laboratory and MRI evaluation at baseline, 3 months, 6 months and 1 year. Magnetic resonance images were analysed using modified Spondyloarthritis Research Consortium of Canada (SPARCC) scoring system. Correlations between MRI score and clinical and laboratory parameters were analysed using Spearman's rank correlation test. RESULTS: Persistent improvement was observed after 12 months in terms of total modified SPARCC scores (37(12,59) vs. 23(5,45) at baseline and 12 months, p<0.05). Total modified SPARCC scores showed Spearman correlations with hypersensitive C-reaction protein (hs-CRP), ankylosing spondylitis disease activity score (ASDAS) and bath ankylosing spondylitis metroloty index (BASMI) at baseline, 3 months, 6 months and 12 months (p varied from <0.001 to <0.05, and r varied from 0.418 to 0.601). Modified SPARCC scores of spine joint, as the largest contribution to the total scores with the mean score of 12(5,30) after 12 months vs. 26 (12,40) at baseline. CONCLUSIONS: The modified SPARCC score proposed in this study exhibits promising potential in the evaluation of extensive radiographic damage in SAPHO and the reflection the disease activity. Our study suggests that MRI could be used together with other parameters of disease activity in the assessment of symptomatic SAPHO patients with spine involvement.

RESUMO

AIMS: To explore the relevance of disease duration with axial skeletal lesions in synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome based on computed tomography (CT). METHODS: Patients who had undergone whole-spine CT were included from a previously reported single-center cohort of SAPHO syndrome. Patients with previous treatments of bisphosphates, biological agents or surgeries were excluded. Sites of axial skeletal involvement were reviewed including the spine, sacroiliac joints, and anterior chest wall. Duration of osteoarticular involvement was defined as the interval between the onset of osteoarticular symptoms and the CT evaluation. RESULTS: Eighty-one patients (54 female and 27 male) were included in the study. The mean disease duration was 26.9 ± 34.9 months. Fifty (63.0%) patients showed spinal lesions on CT. The average numbers of involved vertebral segments for corner and endplate lesions were 3.16 ± 3.51 and 0.73 ± 1.85 respectively. Sixty-eight (84.0%) patients exhibited abnormalities in the anterior chest wall. The number of involved vertebral segments showed poor correlation with disease duration for both corner lesions (r2  = 0.051, P = 0.043) and endplate lesions (r2  = 0.137, P = 0.001). Patients with costoclavicular involvement showed remarkably longer disease duration than those without (49.3 ± 47.7 months vs 18.0 ± 23.5 months, P = 0.006), while no significant difference was detected regarding other structures in the anterior chest wall. CONCLUSION: Costoclavicular involvement is a hallmark of long disease duration in SAPHO syndrome. Corner and endplate lesions in the vertebrae and sacroiliac involvement may not relate to disease course.

RESUMO

Nasopharyngeal carcinoma (NPC) is one of the most common malignant tumors. Studies have indicated that long noncoding RNAs (lncRNAs) function as important regulators in progression of tumorigenesis. In this study, lncRNA small nucleolar RNA host gene 7 (SNHG7) was selected to identify how it functioned in the development of NPC. Real-time quantitative polymerase chain reaction (RT-qPCR) was performed to detect SNHG7 expression in paired NPC patient tissue samples and cell lines. The role of SNHG7 in the metastasis of NPC was detected through scratch wound assay and Transwell assay. RT-qPCR and western blot assay were used to discover the function of SNHG7 in epithelial-to-mesenchymal transition (EMT) process. Tumor metastasis assay was also performed in vivo. In this study, RT-qPCR results showed that SNHG7 expression in NPC samples was remarkably higher when compared with that in adjacent ones. Cell invasion and cell migration of NPC were inhibited due to silence of SNHG7 and were promoted due to overexpression of SNHG7. Moreover, results of further experiments revealed that the EMT-related proteins were regulated via knockdown or overexpression of SNHG7 in NPC. Furthermore, tumor metastasis of NPC was inhibited via knockdown of SNHG7 and was enhanced via overexpression of SNHG7 in nude mice. These results indicate that SNHG7 enhances NPC cell invasion and cell migration by eliciting the EMT process.

RESUMO

Objective: To investigate if the low sodium intake is associated with the plasma carnitine and acylcarnitine profile in children with vasovagal syncope (VVS). Materials and Methods: Twenty-six children suffering from VVS were recruited in the present study and divided into a group of low urinary sodium excretion or a group of normal urinary sodium excretion according to the excretion of 24-h urinary sodium <3 or 3-6 g, respectively. The excretion of 24-h urinary sodium was detected with ion-selective electrode approach. Plasma carnitine and acylcarnitine concentrations were measured with tandem mass spectrometry. Each participant completed the head-up tilt test. The demographics, clinical characteristics, hemodynamic parameters and plasma carnitine and acylcarnitine concentrations were compared between the two groups. A bivariate correlation between plasma acylcarnitine profiles and the excretion of 24-h urinary sodium was conducted with Spearman's correlation coefficients. Results: Of the enrolled VVS patients, 14 patients were assigned to the group of low urinary sodium excretion and the remaining 12 patients were assigned to the group of normal urinary sodium excretion. Symptoms of fatigue were more prevalent in the group of low urinary sodium excretion than in the group of normal urinary sodium excretion (p = 0.009). Aside from fatigue, no other differences in the demographics, clinical characteristics or hemodynamic parameters during the head-up tilt test were found between the two groups (p > 0.05). Concentrations of plasma tiglylcarnitine (C5:1), hydroxyhexadecanoylcarnitine (C16OH), hydroxyoctadecanoylcarnitine (C18OH), and carnitine C22 were significantly higher in the group of low urinary sodium excretion than in the group of normal urinary sodium excretion (all p-values = 0.048); moreover, they were all negatively correlated with 24-h urinary sodium levels (all p-values = 0.016). There were no differences between the two groups in other acylcarnitines or free carnitine. Conclusions: Reduced excretion of 24-h urinary sodium is associated with a disturbed plasma acylcarnitine profile in children with VVS. The findings suggest that restricted sodium intake-induced disturbance of plasma acylcarnitines and related cellular energy metabolism might be involved in the pathogenesis of VVS in children.
