ABSTRACT
The functional neurons are basic building blocks of the nervous system and are responsible for transmitting information between different parts of the body. However, it is less known about the interaction between the neuron and the field. In this work, we propose a novel functional neuron by introducing a flux-controlled memristor into the FitzHugh-Nagumo neuron model, and the field effect is estimated by the memristor. We investigate the dynamics and energy characteristics of the neuron, and the stochastic resonance is also considered by applying the additive Gaussian noise. The intrinsic energy of the neuron is enlarged after introducing the memristor. Moreover, the energy of the periodic oscillation is larger than that of the adjacent chaotic oscillation with the changing of memristor-related parameters, and same results is obtained by varying stimuli-related parameters. In addition, the energy is proved to be another effective method to estimate stochastic resonance and inverse stochastic resonance. Furthermore, the analog implementation is achieved for the physical realization of the neuron. These results shed lights on the understanding of the firing mechanism for neurons detecting electromagnetic field.
ABSTRACT
Since 2003, 38 US states and Washington, DC have adopted legislation and/or regulations to strengthen stroke systems of care (SSOCs). This study estimated the impact of SSOC laws on stroke outcomes. We used a coded legal dataset of 50 states and DC SSOC laws (years 2003-2018), national stroke accreditation information (years 1997-2018), data from the Healthcare Cost and Utilization Project (years 2012-2018), and National Vital Statistics System (years 1979-2019). We applied a natural experimental design paired with longitudinal modeling to estimate the impact of having one or more SSOC policies in effect on outcomes. On average, states with one or more SSOC policies in effect achieved better access to primary stroke centers (PSCs) than expected without SSOC policies (ranging from 2.7 to 8.0 percentage points (PP) higher), lower inpatient hospital costs (USD 610-1724 less per hospital stay), lower age-adjusted stroke mortality (1.0-1.6 fewer annual deaths per 100,000), a higher proportion of stroke patients with brain imaging results within 45 min of emergency department arrival (3.6-5.0 PP higher), and, in some states, lower in-hospital stroke mortality (5 fewer deaths per 1000). Findings were mixed for some outcomes and there was limited evidence of model fit for others. No effect was observed in racial and/or rural disparities in stroke mortality.
ABSTRACT
Importance: Current estimates of productivity losses associated with heart disease and stroke in the US include income losses from premature mortality but do not include income losses from morbidity. Objective: To estimate labor income losses associated with morbidity of heart disease and stroke in the US due to missed or lower labor force participation. Design, Setting, and Participants: This cross-sectional study used 2019 Panel Study of Income Dynamics data to estimate labor income losses associated with heart disease and stroke by comparing labor income between persons with and without heart disease or stroke, after controlling for sociodemographic characteristics and other chronic conditions and considering the situation of zero labor income (eg, withdrawal from the labor market). The study sample included individuals aged 18 to 64 years who were reference persons or spouses or partners. Data analysis was conducted from June 2021 to October 2022. Exposure: The key exposure was heart disease or stroke. Main Outcomes and Measures: The main outcome was labor income, measured for the year 2018. Covariates included sociodemographic characteristics and other chronic conditions. Labor income losses associated with heart disease and stroke were estimated using the 2-part model, in which part 1 is to model the probability that labor income is greater than zero and part 2 is to regress positive labor income, with both parts having the same set of explanatory variables. Results: In the study sample consisting of 12â¯166 individuals (6721 [52.4%] females) representing a weighted mean income of $48â¯299 (95% CI, $45â¯712-$50â¯885), the prevalence of heart disease was 3.7% and the prevalence of stroke was 1.7%, and there were 1610 Hispanic persons (17.3%), 220 non-Hispanic Asian or Pacific Islander persons (6.0%), 3963 non-Hispanic Black persons (11.0%), and 5688 non-Hispanic White persons (60.2%). The age distribution was largely even, from 21.9% for the age 25 to 34 years group to 25.8% for the age 55 to 64 years group, except for young adults (age 18-24 years), who made up 4.4% of the sample. After adjustment for sociodemographic characteristics and other chronic conditions, persons with heart disease would receive an estimated $13â¯463 (95% CI, $6993-$19â¯933) less in annual labor income than those without heart disease (P < .001), and persons with stroke would receive an estimated $18â¯716 (95% CI, $10â¯356-$27â¯077) less in annual labor income than those without stroke (P < .001). Total labor income losses associated with morbidity were estimated at $203.3 billion for heart disease and $63.6 billion for stroke. Conclusions and Relevance: These findings suggest that total labor income losses associated with morbidity of heart disease and stroke were far greater than those from premature mortality. Comprehensive estimation of total costs of CVD may assist decision-makers in assessing benefits from averted premature mortality and morbidity and allocating resources to the prevention, management, and control of CVD.

BACKGROUND: Risk factors common to nursing home (NH) residents are potentially not fully captured by the Hospital Readmissions Reduction Program (HRRP). The unique challenges faced by hospitals that disproportionately serve NH residents who are at greater risk of readmissions have not been studied. METHODS: Using 100% Medicare Provider Analysis and Review File and the Minimum Data Set from 2010-2013, we constructed a measure of hospital share of NH-originating hospitalizations (NOHs). We defined hospital share of NOHs as the proportion of inpatient stays by patients aged 65 or older who were directly admitted from NHs. To evaluate the impact of the share of NOHs on readmission penalties, we categorized hospitals into quartiles according to their share of NOHs and estimated the differences in the adjusted penalties across hospital quartiles after accounting for hospital characteristics, market characteristics and state fixed effects. We repeated the analyses for the penalties incurred in each year between 2015 and 2019. RESULTS: Hospitals varied substantially in the share of NOHs (median [interquartile range], 11.3% [8.2%-15.1%]), with limited variation over time. In 2015, hospitals in the highest quartile of NOH received on average 0.58% Medicare payment reduction compared to 0.44% reduction among those in the lowest quartile (32.9% higher penalties, p < 0.001). The increase in penalties continued to grow in 2017 and 2018 when the HRRP expanded to include additional target conditions (47.3% and 66.7%, respectively, p < 0.001 for both). Although the effect diminished in 2019 following the additional adjustment for hospital's dual-eligible share, hospitals in the highest quartile of NOH still incurred 43.0% (p < 0.001) higher penalties than those in the lowest quartile. CONCLUSIONS: Hospitals varied considerably in their share of NOHs. Hospitals having a higher share of NOHs were disproportionately penalized for excess readmissions, even under the revised policy that adjusts for the share of dual-eligible admissions.

Background: Chromosome is the basic framework for eukaryotic cells to store genetic information, but certain genes exist in circulation, such as extrachromosomal circular DNA (eccDNA). The unique genetic characteristics and structure of eccDNA provide a new vision on the early diagnosis of cancer; however, whether eccDNA contributes to the early diagnosis and progression of lung cancer remains unclear. Methods: We performed next-generation sequencing (NGS) analysis of eccDNA from the plasma of 6 lung adenocarcinoma (LUAD) patients. The data of plasma eccDNA of healthy people were obtained from public available database. We compared size distribution, chromosome origin, formation and expression patterns of eccDNA between LUAD patients and those of 6 healthy people and 4 healthy gravidas. Results: A total number of 716,059 eccDNA ranging from 22 bp to 3,297,519 bp were detected with an average size less than 800bp and distinctive bimodality in size around 191 bp and 320 bp. After comparison of eccDNA abundance in each sequencing sample, nine eccDNA were ranked on top with higher frequency in lung adenocarcinoma patients than healthy people. Among them, four eccDNA (DOCK1, PPIC, TBC1D16, and RP11-370A5.1) were uniquely expressed in lung adenocarcinoma patients, which may serve as potential biomarkers for early diagnosis LUAD. Conclusion: Cancer-specific eccDNA was presented in LUAD compared to normal people, which might serve as a promising biomarker in LUAD.
ABSTRACT
A literature review of peer-reviewed articles published 2000-2019 was conducted to determine the types and extent of hypertension-associated productivity loss among adults in the United States. All monetary outcomes were standardized to 2019 $ by using the Employment Cost Index. Twenty-seven articles met the inclusion criteria. Nearly half of the articles (12 articles) presented monetary outcomes of productivity loss. Absenteeism (14 articles) and presenteeism (8 articles) were most frequently assessed. Annual absenteeism was estimated to cost more than $11 billion, nationally controlling for sociodemographic characteristics. The annual additional costs per person were estimated at $63 for short-term disability, $72-$330 for absenteeism, and $53-$156 for presenteeism, controlling for participant characteristics; and may be as high as $2362 for absenteeism and presenteeism when considered in combination. The annual additional time loss per person was estimated as 1.3 days for absenteeism, controlling for common hypertension comorbidities, including stroke and diabetes; and 15.6 days for work and home productivity loss combined, controlling for sociodemographic characteristics. The loss from absenteeism alone might be more than 20% of the total medical expenditure of hypertension. Although the differences in estimation methods and study populations make it challenging to synthesize the costs across the studies, this review provides detailed information on the various types of productivity loss. In addition, the ways in which methods could be standardized for future research are discussed. Accounting for the costs from productivity loss can help public health officials, health insurers, employers, and researchers better understand the economic burden of hypertension.

Variations in the visceral vasculature are often encountered, but rarely cause clinical symptoms. We report a 12-year-old girl with portal hypertension caused by congenital variations in visceral vessels. The clinical manifestations included gastrointestinal hemorrhage and ascites. The common hepatic artery and splenic artery stem shared the same trunk from the aorta, and the common hepatic artery was directly connected with the main portal vein to form an arteriovenous fistula. In addition, the left hepatic artery and the left gastric artery shared a common trunk termed the "hepatic-gastric trunk" which originated from the anterior wall of the aorta, while the right hepatic artery originated from the superior mesenteric artery and supplied the right liver. The patient was treated with interventional embolization and remained in good condition throughout the follow-up and at the time of publication.
ABSTRACT
PURPOSE: The survival benefits of patients with inoperable hepatocellular carcinoma (HCC) who undergo transarterial chemoembolization (TACE) and receive sorafenib therapy remain controversial. We aimed to identify clinical predictors in patients with inoperable HCC undergoing TACE and receiving sorafenib. METHODS: Between January 2014 and December 2017, 148 consecutive patients with inoperable HCC who were treated with TACE plus sorafenib were retrospectively analyzed. Critical clinical factors associated with overall survival (OS) were identified by Cox regression model analysis. Kaplan-Meier methods were used to calculate the survival times, which were compared with the log-rank test. RESULTS: Macrovascular invasion (MVI), radiologic response and sorafenib-related dermatologic toxicities were identified as independent factors associated with OS. MVI is a known prognostic factor before treatment. The median OS of patients with either radiologic response or dermatologic toxicities was significantly improved compared with that of patients without it (both 23.0 vs. 7.0 months, P < 0.001). The median OS of patients with a combination of radiologic response and dermatologic toxicities was significantly longer than that of patients with either radiologic response or dermatologic toxicities, as well as no response (25.0 vs. 14.0 vs. 6.0 months, respectively, P < 0.001), and the predictive value was confirmed across patients with different baseline characteristics in terms of MVI, α-fetoprotein level, performance status and liver function. CONCLUSION: The combination of radiologic response and sorafenib-related dermatologic toxicities is the most robust predictor of survival benefits for HCC patients after TACE plus sorafenib therapy. LEVEL OF EVIDENCE: Level 3.

Productive aging, or older adults engaging in paid or unpaid activities that produce socially valued goods or services, has been suggested to have the beneficial impact on older adults' health and well-being. We performed a cross-sectional study to examine the influence of health literacy on the relationship between socioeconomic status (SES) and productive aging among older Chinese adults in a newly urbanized community. Data was collected from 995 older adults from a newly urbanized community between June and August 2013 in Chengdu, China. We used structural equation modeling (SEM) to test the hypothesized relationship among SES, health literacy and productive aging. Results showed that education attainment and income had a direct positive effect on health literacy (ß = 0.47and ß = 0.15, respectively). Education had a partial indirect effect on productive aging through health literacy (ß = 0.27). And health literacy was an important factor in improving the productive aging of the elderly. Interventions targeting health education and health promotion should be taken to improve health literacy of older adults under the background of urbanization, especially for those with lower SES.

Prussian blue nanoprobes are widely studied and applied in tumor photothermal therapy (PTT) and magnetic resonance imaging (MRI), due to their low toxicity and excellent in vivo performance. However, the sizes of hitherto reported Prussian blue nanoprobes are generally larger than 50 nm, which greatly influence cell phagocytosis, in vivo circulation, and biodistribution. In this work, a novel method of doping zinc ions is used to control the size of Prussian blue nanoprobes. Consequently, the performances of the nanoprobes in PTT and MRI are both significantly improved. The results show that the minimum size of Prussian blue nanoprobes achieved by doping 10% zinc ions (abbreviated as SPBZn(10%)) is 3.8 ± 0.90 nm, and the maximum specific absorption coefficient, photothermal conversion efficiency, and longitudinal relaxation rates are 1.78 L g-1 cm-1 , 47.33%, and 18.40 mm-1 s-1 , respectively. In addition, the SPBZn(10%) nanoprobes provide excellent PTT efficacy on 4T1 tumor cells (killing rate: 90.3%) and breast cancer model (tumor inhibition rate: 69.4%). Toxicological experiment results show that the SPBZn(n%) nanoprobes exhibit no obvious in vitro cytotoxicity and they can be used safely in mice at doses below 100 mg kg-1 . Therefore, SPBZn(10%) nanoprobes can potentially be used for effective cancer theranostics.

In the past few decades, upconversion nanoparticles (abbreviated as UCNPs) have been more widely applied in the biomedical fields, such as in vitro and in vivo upconversion fluorescent bioimaging, photodynamic therapy, biological macromolecular detection, imaging mediated drug delivery and so on. But meanwhile, there is still not much research on the acute toxicity of upconversion nanoparticles in vivo, such as acute hepatotoxicity. In this work, we studied the in vivo biodistribution and acute hepatotoxicity of multimodal targeted contrast agent NaLuF4:Gd,Yb,Er-PEG/PEI-FA nanoprobe, which were synthesized by the solvothermal method and modified with Polyethylene glycol (PEG), Polyetherimide (PEI), folic acid (FA) on the surface. The acute hepatotoxicity in mice was systematically assessed after tail vein injection of different concentration of UCNPs. The results showed that NaLuF4:Gd,Yb,Er-PEG/PEI-FA nanoparticles with an average diameter of 44.5 ± 10.4 nm, and three typical upconversion fluorescence emission bands at 520 nm, 540 nm and 660 nm under the excitation of 980 nm laser. In vivo distribution experiments results demonstrated that approximately 87% of UCNPs injected through the tail vein accumulate in the liver. In the acute hepatotoxicity test, the intravenously injection dose of UCNPs was 10, 40, 70 and 100 mg/kg, respectively. The body weight, blood routine, serum biochemistry, histomorphology and liver oxidative stress were detected and observed no significant acute hepatotoxicity damage under the injection dose of 100 mg/kg. In conclusion, NaLuF4:Gd,Yb,Er-PEG/PEI-FA nanoprobes are safe and reliable, and have potential applications in the field of tumor targeted multimodal imaging.

OBJECTIVE: To explore influential factors contributing to the choice of primary care facilities (PCFs) for the initial treatment among rural and urban residents in Southwestern China. METHODS: A face-to-face survey was conducted on a multistage stratified random sample of 456 rural and 459 urban residents in Sichuan Province from January to August in 2014. A structured questionnaire was used to collect data on residents' characteristics, provider of initial treatment and principal reason for the choice. Multivariate logistic regression was performed to identify factors associated with choosing PCFs for the initial treatment. RESULTS: The result showed that 65.4% of the rural residents and 50.5% of the urban residents chose PCFs as their initial contact for medical care. Among both rural and urban residents, the principal reason for choosing medical institutions for the initial treatment was convenience (42.3% versus 40.5%, respectively), followed by high quality of medical care (26.5% versus 29.4%, respectively). Compared to rural residents, urban residents were more likely to value trust in doctors and high quality of medical care but were less likely to value the insurance designation status of the facilities. Logistic regression analysis showed that both rural and urban residents were less likely to choose PCFs for the initial treatment if they lived more than 15 minutes (by walk) from the nearest facilities (rural: OR = 0.15, 95%CI = 0.09-0.26; urban: OR = 0.19, 95%CI = 0.10-0.36), had fair (rural: OR = 0.49, 95%CI = 0.26-0.92; urban: OR = 0.31, 95%CI = 0.15-0.64) or poor (rural: OR = 0.14, 95%CI = 0.07-0.30; urban: OR = 0.22, 95%CI = 0.11-0.44) self-reported health status. Among rural residents, attending college or higher education (OR = 0.21, 95%CI = 0.08-0.59), being retired (OR = 0.90, 95%CI = 0.44-1.84) and earning a per capita annual income of household of 10,000-29,999 (OR = 0.24, 95%CI = 0.11-0.52) and 30,000-49,999 (OR = 0.26, 95%CI = 0.07-0.92) were associated with lower rates of seeking care at PCFs. CONCLUSION: Efforts should be made to improve the accessibility of PCFs and to upgrade the services capability of PCFs both in rural and urban areas in China. At the same time, resources should be prioritized to residents with poorer self-reported health status, and rural residents who retire or have better education and higher income levels should be taken into account.

Retroperitoneal ectopic pregnancy (REP) is an extremely rare type of ectopic pregnancy. Currently, surgery is the most widely used treatment method although it involves a high likelihood of intraoperative hemorrhage. In this case report, we describe a safe and effective alternative method for managing epigastric REP. We conducted a retrospective analysis of the clinical data of 2 patients with REP in the epigastrium who were treated at our hospital using our nonsurgical method. The treatment involved conservative management by computed tomographic-guided methotrexate injection in the gestational sac. We also present a literature review of 26 case reports and discuss the clinical features and various methods for treating REP. Our experience with the successful treatment of 2 patients suggests that the novel approach of computed tomographic-guided methotrexate injection in the gestational sac may be a safe and effective approach to manage REP. Further studies are warranted to confirm our findings.

The rarity and non-specific symptoms of benign primary tracheal tumors always leaded to misdiagnosis and delayed treatment, and also undefined the optimal treatment. In this case, a 45-year-old woman had a history of progressive shortness of breath and dry cough for several years, CT scan revealed an intra-luminal tracheal mass invaded the left side of tracheal wall. After being located by bronchoscope preoperatively, the tumor was removed by surgical resection. The tumor was 1.5 cm in diameter with intact capsule. The pathological result confirmed the diagnosis of schwannoma.
ABSTRACT
BACKGROUND: The 2014 Institute of Medicine report recommended that healthcare providers caring for individuals with advanced illness have basic palliative care competencies in communication, inter-professional collaboration, and symptom management. Nursing homes, where one in three American decedents live and die, have fallen short of these competency goals. We implemented an intervention study to examine the efficacy of nursing home-based integrated palliative care teams in improving the quality of care processes and outcomes for residents at the end of life. METHODS/DESIGN: This paper describes the design, rationale, and challenges of a two-arm randomized controlled trial of nursing home-based palliative care teams in 31 facilities. The impact of the intervention on residents' outcomes is measured with four risk-adjusted quality indicators: place of death (nursing home or hospital), number of hospitalizations, and self-reported pain and depression in the last 90-days of life. The effect of the intervention is also evaluated with regard to staff satisfaction and impact on care processes (e.g. palliative care competency, communication, coordination). Both secondary (e.g. the Minimum Data Set) and primary (e.g. staff surveys) data are employed to examine the effect of the intervention. DISCUSSION: Several challenges in conducting a complex, nursing home-based intervention have been identified. While sustainability of the intervention without research funding is not clear, we surmise that without changes to the payment model that put palliative care services in this care setting on par with the more "skilled" care, it will not be reasonable to expect any widespread efforts to implement facility-based palliative care services.

BACKGROUND: One proposed strategy to expand primary care capacity is to use nurse practitioners (NPs) more effectively in health care delivery. However, the ability of NPs to provide care to the fullest extent of their education is moderated by state scope-of-practice (SOP) regulations. PURPOSE: The purpose of this study was to examine the impact of state SOP regulations on the following three key issues: (a) NP workforce, (b) access to care and health care utilization, and (c) health care costs. METHODS: Systematic review. RESULTS/DISCUSSION: States granting NPs greater SOP authority tend to exhibit an increase in the number and growth of NPs, greater care provision by NPs, and expanded health care utilization, especially among rural and vulnerable populations. Our review indicates that expanded NP practice regulation can impact health care delivery by increasing the number of NPs in combination with easing restrictions on their SOP. CONCLUSIONS: Findings show promise that removing restrictions on NP SOP regulations could be a viable and effective strategy to increase primary care capacity.

BACKGROUND: Quality report cards have been shown to be effective in influencing patients' referrals and promoting quality improvement in some instances and not others. In this study, we investigate one of the mechanisms that may detract from their effectiveness: voluntary versus mandatory participation of nursing homes in public quality reporting. OBJECTIVES: To answer 2 questions: (1) Were the nursing homes choosing not to participate low-quality performers relative to those who chose to participate? (2) Once participation became mandatory, did those that did not voluntarily participate initially, improve more than those that participated voluntarily? RESEARCH DESIGN: Massachusetts published the Massachusetts Satisfaction Survey report card for nursing homes for the years 2005, 2007, and 2009. Nursing homes' participation was voluntary in 2005 and mandatory in 2007 and 2009. We performed a retrospective statistical analysis of the relationship between nursing homes' decision to participate in quality reporting and 12 quality outcomes: deficiency citations, staffing, and 8 survey domains. SUBJECTS: A total of 424 Massachusetts nursing homes. RESULTS: Sixty-seven percent of nursing homes participated in reporting voluntarily. Volunteer nursing homes had better quality for all measures (significant at the 0.05 level or trending toward significance at the 0.10 level for all but 2). Once reporting became mandatory, nonvolunteers improved more than volunteers in all but 2 staffing measures (trending toward significance at the 0.10 level in 5). CONCLUSIONS: Report cards are more effective if nursing homes' participation is mandated. Nonmandatory reporting systems, as those implemented by some states and professional associations, lead to missed opportunities for quality improvements.

OBJECTIVE To examine the prevalence of healthcare-associated pathogens and the infection control policies and practices in a national sample of nursing homes (NHs). METHODS In 2012, we conducted a national survey about the extent to which NHs follow suggested infection control practices with regard to 3 common healthcare-associated pathogens: methicillin-resistant Staphylococcus aureus, Clostridium difficile, and extended-spectrum ß-lactamase producers, and their prevalence in NHs. We adapted a previously used and validated NH infection control survey, including questions on prevalence, admission and screening policies, contact precautions, decolonization, and cleaning practices. RESULTS A total of 1,002 surveys were returned. Of the responding NHs, 14.2% were less likely to accept residents with methicillin-resistant Staphylococcus aureus, with the principal reason being lack of single or cohort rooms. NHs do not routinely perform admission screening (96.4%) because it is not required by regulation (56.2%) and would not change care provision (30.7%). Isolation strategies vary substantially, with gloves being most commonly used. Most NHs (75.1%) do not decolonize carriers of methicillin-resistant Staphylococcus aureus, but some (10.6%) decolonize more than 90% of residents. Despite no guidance on how resident rooms on contact precautions should be cleaned, 59.3% of NHs report enhanced cleaning for such rooms. CONCLUSION Overall, NHs tend to follow voluntary infection control guidelines only if doing so does not require substantial financial investment in new or dedicated staff or infrastructure.
