The epidemiology of dying within 48 hours of presentation to emergency departments: a retrospective cohort study of older people across Australia and New Zealand.

BACKGROUND: Emergency department (ED) clinicians are more frequently providing care, including end-of-life care, to older people. OBJECTIVES: To estimate the need for ED end-of-life care for people aged ≥65 years, describe characteristics of those dying within 48 hours of ED presentation and compare those dying in ED with those dying elsewhere. METHODS: We conducted a retrospective cohort study analysing data from 177 hospitals in Australia and New Zealand. Data on older people presenting to ED from January to December 2018, and those who died within 48 hours of ED presentation, were analysed using simple descriptive statistics and univariate logistic regression. RESULTS: From participating hospitals in Australia or New Zealand, 10,921 deaths in older people occurred. The 48-hour mortality rate was 6.43 per 1,000 ED presentations (95% confidence interval: 6.31-6.56). Just over a quarter (n = 3,067, 28.1%) died in ED. About one-quarter of the cohort (n = 2,887, 26.4%) was triaged into less urgent triage categories. Factors with an increased risk of dying in ED included age 65-74 years, ambulance arrival, most urgent triage categories, principal diagnosis of circulatory system disorder, and not identifying as an Aboriginal or Torres Strait Islander person. Of the 7,677 older people admitted, half (n = 3,836, 50.0%) had an encounter for palliative care prior to, or during, this presentation. CONCLUSIONS: Our findings provide insight into the challenges of recognising the dying older patient and differentiating those appropriate for end-of-life care. We support recommendations for national advanced care planning registers and suggest a review of triage systems with an older person-focused lens.

The Physical Health Nurse Consultant: Perceptions and Experiences of Those Who Care for People with Mental Illness.

Mental health carers are crucial in improving the physical health outcomes of people diagnosed with a mental illness (hereafter referred to as consumers). The long-term and multifaceted mental and physical health support carers provide to consumers can contribute to caregiver burden. Consequently, carers advocate for coordinated and integrated physical healthcare to improve the physical health outcomes of consumers and alleviate caregiver burden. The aim of this qualitative exploratory study is to explore carers' perceptions and experiences with the Physical Health Nurse Consultant role. Semi-structured interviews with nine carers nominated by consumers were conducted. Interviews were transcribed and reflexively thematically analysed. Three main themes were identified: (i) Therapeutic relationship s were a catalyst for health behaviour change; (ii) Overt and covert positive changes were observed by carer and (iii) Cares' involvement in integrated mental health and physical health care. Nine carers who were nominated by consumers to be involved in their physical healthcare planning, preferred to adopt a supporting role as this prevented or reduced caregiver burden. The findings support the adoption and continuation of the Physical Health Nurse Consultant role to facilitate positive physical health outcomes for consumers and a reduction in caregiving burden. The benefits of the Physical Health Nurse Consultant provide a compelling argument to embed the role in routine practice. Mental healthcare services should advocate for continued funding and career development for such positions to provide long term benefits for consumers and carers. Future research is required to explore carer and consumer involvement in co-producing future and localised iterations of the Physical Health Nurse Consultant role. This research should also measure the outputs and outcomes of co-production to clarify how the process worked in practice.

Emergency department presentations during the COVID-19 pandemic in Queensland (to June 2021): interrupted time series analysis.

OBJECTIVES: To assess emergency department (ED) presentation numbers in Queensland during the coronavirus disease 2019 (COVID-19) pandemic to mid-2021, a period of relatively low COVID-19 case numbers. DESIGN: Interrupted time series analysis. SETTING: All 105 Queensland public hospital EDs. MAIN OUTCOME MEASURES: Numbers of ED presentations during the COVID-19 lockdown period (11 March 2020 - 30 June 2020) and the period of easing restrictions (1 July 2020 - 30 June 2021), compared with pre-pandemic period (1 January 2018 - 10 March 2020), overall (daily numbers) and by Australasian Triage Scale (ATS; daily numbers) and selected diagnostic categories (cardiac, respiratory, mental health, injury-related conditions) and conditions (stroke, sepsis) (weekly numbers). RESULTS: During the lockdown period, the mean number of ED presentations was 19.4% lower (95% confidence interval, -20.9% to -17.9%) than during the pre-pandemic period (predicted mean number: 5935; actual number: 4786 presentations). The magnitudes of the decline and the time to return to predicted levels varied by ATS category and diagnostic group; changes in presentation numbers were least marked for ATS 1 and 2 (most urgent) presentations, and for presentations with cardiac conditions or stroke. Numbers remained below predicted levels during the 12-month post-lockdown period for ATS 5 (least urgent) presentations and presentations with mental health problems, respiratory conditions, or sepsis. CONCLUSIONS: The COVID-19 pandemic and related public restrictions were associated with profound changes in health care use. Pandemic plans should include advice about continuing to seek care for serious health conditions and health emergencies, and support alternative sources of care for less urgent health care needs.

Validation of diagnosis codes in healthcare databases in Taiwan, a literature review.

PURPOSE: To compile validation findings of diagnosis codes and related algorithms for health outcomes of interest from National Health Insurance (NHI) or electronic medical records in Taiwan. METHODS: We carried out a literature review of English articles in PubMed® and Embase from 2000 through July 2022 with appropriate search terms. Potentially relevant articles were identified through review of article titles and abstracts, full text search of methodology terms "validation", "positive predictive value", and "algorithm" in Subjects & Methods (or Methods) and Results sections of articles, followed by full text review of potentially eligible articles. RESULTS: We identified 50 published reports with validation findings of diagnosis codes and related algorithms for a wide range of health outcomes of interest in Taiwan, including cardiovascular diseases, stroke, renal impairment, malignancy, diabetes, mental health diseases, respiratory diseases, viral (B and C) hepatitis, and tuberculosis. Most of the reported PPVs were in the 80% ~ 99% range. Assessment of algorithms based on ICD-10 systems were reported in 8 articles, all published in 2020 or later. CONCLUSIONS: Investigators have published validation reports that may serve as empirical evidence to evaluate the utility of secondary health data environment in Taiwan for research and regulatory purpose.

Interventions and strategies to prevent medical device-related pressure injury in adult patients: A systematic review.

BACKGROUND: Current evidence shows that medical device-related pressure injury (MDRPI) has a high prevalence (10%) and incidence (12%), and much research has been done to prevent MDRPI in recent years. However, to our knowledge, there is limited systematic review available on interventions and strategies to prevent MDRPI. AIM: To synthesise research evidence on interventions and strategies used to prevent MDRPI. METHODS: This systematic review adhered to the PRISMA Guidelines. We searched six databases including Medline, CINAHL, EMBASE, Cochrane library, Web of Science and ProQuest with no restriction to year of publication. Data were extracted and checked by two authors independently. A narrative summary technique was used to describe the findings. Implementation strategies were grouped into six classifications: dissemination/implementation process/integration/capacity building/sustainability/scale-up strategies. RESULTS: Twenty-four peer-reviewed papers met the inclusion criteria, which comprised of 11 quality improvement projects and 13 original research. Types of devices included respiratory devices (non-invasive ventilation mask, CPAP/BiPAP mask, endotracheal tube), gastrointestinal/urinary devices and other devices. Interventions used included the use of dressing, hyperoxygenated fatty acids, full-face mask, training, and/or multidisciplinary education, use of special securement devices or tube holder, repositioning, application of stockinette, early removal and foam ring use. Common implementation strategies included ongoing staff education, audit and standardising documentation or guideline development. CONCLUSION: Much work on MDRPI prevention strategies has been undertaken. There were a variety of devices reported, however, it is evident that higher quality research is needed. RELEVANCE TO CLINICAL PRACTICE: Current evidence shows that interventions including use of dressing or special securement device, repositioning, and training/multidisciplinary education can be beneficial for MDRPI prevention. High-quality research, such as randomised controlled trials are needed to test the effectiveness of the interventions and their implementation strategies. No patient or public contribution.

Innate immune response analysis in COVID-19 and kawasaki disease reveals MIS-C predictors.

BACKGROUND/PURPOSE: The association between dysregulated innate immune responses seen in Kawasaki disease (KD) with predisposition to Kawasaki-like multisystem inflammatory syndrome in children (MIS-C) remains unclear. We aimed to compare the innate immunity transcriptome signature between COVID-19 and KD, and to analyze the interactions of these molecules with genes known to predispose to KD. METHODS: Transcriptome datasets of COVID-19 and KD cohorts (E-MTAB-9357, GSE-63881, GSE-68004) were downloaded from ArrayExpress for innate immune response analyses. Network analysis was used to determine enriched pathways of interactions. RESULTS: Upregulations of IRAK4, IFI16, STING, STAT3, PYCARD, CASP1, IFNAR1 and CD14 genes were observed in blood cells of acute SARS-CoV-2 infections with moderate severity. In the same patient group, increased expressions of TLR2, TLR7, IRF3, and CD36 were also noted in blood drawn a few days after COVID-19 diagnosis. Elevated blood PYCARD level was associated with severe COVID-19 in adults. Similar gene expression signature except differences in TLR8, NLRP3, STING and IRF3 levels was detected in KD samples. Network analysis on innate immune genes and genes associated with KD susceptibility identified enriched pathways of interactions. Furthermore, higher expression levels of KD susceptibility genes HLA-DOB, PELI1 and FCGR2A correlated with COVID-19 of different severities. CONCLUSION: Our findings suggest that most enriched innate immune response pathways were shared between transcriptomes of KD and COVID-19 with moderate severity. Genetic polymorphisms associated with innate immune dysregulation and KD susceptibility, together with variants in STING and STAT3, might predict COVID-19 severity and potentially susceptibility to COVID-19 related MIS-C.

Influence of social interactions, professional supports and fear of death on adults' preferences for life-sustaining treatments and palliative care.

AIM: To explore the significance of culture, professional support in the community, social interactions and intrapersonal determinants of adults' preferences for life-sustaining treatments and palliative care. METHODS: A cross-sectional design with a Social Ecological Model was used. Between 1 October 2012 and 31 December 2012, 474 adults aged ≥20 years living in a city of Southern Taiwan completed the survey. Data were analysed using hierarchical multiple regression. RESULTS: The life-sustaining measures model was significant with 15.3% (p < 0.0001) of the variance in the Modified Emmanuel Medical Directives being explained by variables of death of self and healthcare services' support. The palliative care model was significant with 18% (p < 0.0001) of the variance in the Modified Hospice Attitude Scale being explained by variables of palliative care knowledge, death of self and social interactions. However, cultural value adherence did not predict adults' preferences for life-sustaining measures and community resources support did not predict palliative care preference. CONCLUSIONS: Findings enhance our understanding of the significance of different societal levels on adults' preferences for end-of-life care. Palliative care knowledge, fear of death, healthcare services' support and social interactions are essential factors that need to be taken into consideration when it comes to discussion about life-sustaining treatments and palliative care.

TNIP2 mediates GRß-promoted inflammation and is associated with severity of major depressive disorder.

In depression, continual activation of the hypothalamic-pituitaryadrenal (HPA) axis with excess cortisol release leads to impair sensitivity of the glucocorticoid receptor (GR) and increase activity of the pro-inflammatory immune responses. Aberrant expression of GR has been associated with inflammation in patients with major depressive disorder (MDD). Our previous studies showed that the aberrant expression of TNFAIP3 gene, which encodes the NF-κB regulatory protein A20, TNFAIP3-associated proteins and Toll-like receptors (TLRs) are involved in inflammation-associated depression. However, the link between desensitization of GR actions and negative regulation of the TLRs-mediated inflammatory pathway in MDD is yet to be established. Here, we examined the association of depression severity, measured via the 17-item Hamilton Depression Rating Scale (HAMD-17), with the mRNA expression profiling of GRα, GRß, TNFAIP3-interacting proteins (TNIP), including TNIP1, TNIP2, and TNIP3, and TNFAIP3-like proteins, such as cezanne1, cezanne2, trabid, and valosin-containing protein p97/p47 complex-interacting protein p135 (VCIP135), in monocytes from 69 patients with MDD and 42 healthy controls. Herein we found the mRNA expressions of GRß and TNIP2 were significantly higher in monocytes from patients with MDD. Notably, TNIP2 level was positively correlated with the GRß expression and severity of depression, as determined via Pearson's correlation analysis. Mechanistically, we demonstrated that overexpression of GRß promotes the mRNA levels of TNIP2 and tumor necrosis factor alpha (TNF-α) in human monocytes. The promoting effect of GRß on TNF-α expression was partially attenuated upon depletion of TNIP2, suggesting that TNIP2 was required for GRß-mediated enhancement of TNF-α levels. Together, these results suggest that activation of GRß/TNIP2/TNF-α axis may induce inflammation in MDD patients and targeting this newly identified pathway may help in the development of better therapeutic approaches to reduce the development of MDD.

Clinical features and outcomes of combined hepatocellular carcinoma and cholangiocarcinoma versus hepatocellular carcinoma versus cholangiocarcinoma after surgical resection: a propensity score matching analysis.

BACKGROUND: Combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) is an infrequent type of primary liver cancer that comprises hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). This study investigated the clinicopathological features and prognosis among cHCC-CC, HCC, and CC groups. METHODS: We prospectively collected the data of 608 patients who underwent surgical resection for liver cancer between 2011 and 2018 at E-Da Hospital, I-Shou University, Kaohsiung, Taiwan. Overall, 505 patients with cHCC-CC, HCC, and CC were included, and their clinicopathological features, overall survival (OS), and recurrence were recorded. OS and recurrence rates were analyzed using the Kaplan-Meier analysis. RESULTS: In the entire cohort, the median age was 61 years and 80% were men. Thirty-five (7.0%) had cHCC-CC, 419 (82.9%) had HCC, and 51 (10.1%) had CC. The clinicopathological features of the cHCC-CC group were more identical to those of the HCC group than the CC group. OS was significantly lower in the cHCC-CC group than in the HCC group but was not significantly higher in the cHCC-CC group than in the CC group. The median OS of cHCC-CC, HCC, and CC groups was 50.1 months [95% confidence interval (CI): 38.7-61.2], 62.3 months (CI: 42.1-72.9), and 36.2 months (CI: 15.4-56.5), respectively. Cumulative OS rates at 1, 3, and 5 years in cHCC-CC, HCC, and CC groups were 88.5%, 62.2%, and 44.0%; 91.2%, 76.1%, and 68.0%; and 72.0%, 48.1%, and 34.5%, respectively. After propensity score matching (PSM), OS in the cHCC-CC group was not significantly different from that in the HCC or CC group. However, OS was significantly higher in the HCC group than in the CC group before and after PSM. Furthermore, the disease-free survival was not significantly different among cHCC-CC, HCC, and CC groups before and after PSM. CONCLUSION: The clinicopathological features of the cHCC-CC group were more identical to those of the HCC group than the CC group. The OS rate was significantly lower in the cHCC-CC group than the HCC group. However, after PSM, OS and disease-free survival in the cHCC-CC group were not significantly different from those in the HCC or CC group.

Use of antidiabetic medications and risk of chronic obstructive pulmonary disease exacerbation requiring hospitalization: a disease risk score-matched nested case-control study.

BACKGROUND: Exacerbation of chronic obstructive pulmonary disease (COPD) severely impacts the quality of life and causes high mortality and morbidity. COPD is involved with systemic and pulmonary inflammation, which may be attenuated with antidiabetic agents exerting anti-inflammatory effects. Real-world evidence is scant regarding the effects of antidiabetic agents on COPD exacerbation. Accordingly, we conducted a disease risk score (DRS)-matched nested case-control study to systemically assess the association between each class of oral hypoglycemic agents (OHAs) and risk of severe COPD exacerbation in a nationwide COPD population co-diagnosed with diabetes mellitus (DM). METHODS: We enrolled 23,875 COPD patients receiving at least one OHA for management of DM by analyzing the Taiwan National Health Insurance claims database between January 1, 2000, and December 31, 2015. Cases of severe exacerbation were defined as those who had the first hospital admission for COPD. Each case was individually matched with four randomly-selected controls by cohort entry date, DRS (the estimated probability of encountering a severe COPD exacerbation), and COPD medication regimens using the incidence density sampling approach. Conditional logistic regressions were performed to estimate odds ratios (OR) of severe COPD exacerbation for each type of OHAs. RESULTS: We analyzed 2700 cases of severe COPD exacerbation and 9272 corresponding controls after DRS matching. Current use of metformin versus other OHAs was associated with a 15% (adjusted OR [aOR], 0.85; 95% confidence interval [CI] 0.75-0.95) reduced risk of severe COPD exacerbation, whereas the reduced risk was not observed with other types of antidiabetic agents. When considering the duration of antidiabetic medication therapy, current use of metformin for 91-180 and 181-365 days was associated with a 28% (aOR, 0.72; 95% CI 0.58-0.89) and 37% (aOR, 0.63; 95% CI 0.51-0.77) reduced risk of severe COPD exacerbation, respectively. Similarly, 91-180 days of sulfonylureas therapy led to a 28% (aOR, 0.72; 95% CI 0.58-0.90) lower risk, and longer treatments consistently yielded 24-30% lower risks. Current use of thiazolidinediones for more than 181 days yielded an approximately 40% decreased risk. CONCLUSIONS: Duration-dependent beneficial effects of current metformin, sulfonylurea, and thiazolidinedione use on severe COPD exacerbation were observed in patients with COPD and DM.

Use of antipsychotics and the risk of acute respiratory failure among adults: A disease risk score-matched nested case-control study.

AIMS: Evidence on acute respiratory failure (ARF) from antipsychotics is scant, and only 1 population-based study examined this drug safety issue in chronic obstructive pulmonary disease patients. Antipsychotics have been frequently prescribed off-label in adults, but whether antipsychotic use carries an increased ARF risk among adult patients is uncertain. METHODS: We adopted a nested case-control study analysing 716 493 adults aged ≥20 years, identified from the Taiwan nationwide healthcare claims records between January 2000 and December 2013. Among the study cohort, 7084 adults with ARF and 12,785 disease risk scored-matched randomly selected controls were analysed. Multivariable logistic regression models were employed to estimate odds ratios of ARF with antipsychotic usages. RESULTS: Current, recent, and recent past use of antipsychotics was associated with a 2.33-fold (95% confidence interval [CI] = 2.06-2.64), 1.79-fold (95% CI = 1.43-2.25) and 1.41-fold (95% CI = 1.20-1.66) increased risk of ARF, respectively, compared with nonuse, while antipsychotics discontinued >90 days carried no risk. A dose-dependent association was observed with current therapy of antipsychotics (test for trend, P < .001), in which antipsychotic use at >1 defined daily dose yielded the highest risk of 6.53-fold (95% CI = 3.33-12.79). The findings were robust to using carbamazepine as an active comparator. CONCLUSION: Antipsychotic use was associated with an increased risk of ARF in adult patients. The risk was dose-dependent and markedly higher with current use of antipsychotic agents at doses of 1 defined daily dose and above, <10% of this cohort. Physicians should be vigilant about any respiratory symptoms in patients currently receiving antipsychotics at such dose.

Risk of severe hypoglycemic events from amiodarone-sulfonylureas interactions: A population-based nested case-control study.

PURPOSE: To evaluate whether concomitant use of amiodarone and sulfonylureas is associated with an increased risk of serious hypoglycemia. METHODS: We conducted two nested case-control studies by analyzing the Taiwan National Health Insurance Research Database from 2008 to 2013 among diabetic patients continuously receiving sulfonylureas. Cases were defined as patients with severe hypoglycemia and those with a composite outcome of severe hypoglycemia, altered consciousness, and fall-related fracture in the first and second study, respectively. In both studies, each case was individually matched up to 10 randomly-selected controls. Conditional logistic regressions were employed to estimate odds ratios (ORs). RESULTS: We identified 1343 cases and 11 597 controls as well as 2848 cases of composite events and 24 808 controls among 46 317 sulfonylurea users. Concurrent use of amiodarone with sulfonylureas was associated with a 1.56-fold (95% CI: 0.98-2.46) increased risk of severe hypoglycemia, despite not statistically significant. Notably, an approximately 2-fold increased risk of severe hypoglycemia was observed with amiodarone therapy lasting for >180 days (adjusted OR: 2.08; 95% CI: 1.01-4.30) or at a daily dose greater than 1 defined daily dose (adjusted OR: 2.21; 95% CI: 1.25-3.91) when concurrently administrating sulfonylureas. A significantly increased risk of hypoglycemia-related composite events was also found with amiodarone concurrently used with sulfonylureas (adjusted OR: 1.59; 95% CI: 1.13-2.24). CONCLUSIONS: Concurrent use of amiodarone and sulfonylureas is associated with an increased risk of serious hypoglycemia among diabetic patients, with an elevated risk for amiodarone used in a long-term or at a high daily dose.

[A method of screening highly common neoantigens with immunogenicity in colorectal cancer based on public somatic mutation library].

Colorectal cancer (CRC) is a malignant cancer with high incidence and mortality in the world. Immunotherapy targeting neoantigens can induce durable tumor regression in cancer patients, but is almost limited to personalized precision therapy, due to the individual differences of unique neoantigens. With the discovery of many common oncogenic mutations, and such mutation-associated neoantigens could cover more patients, and hence are valuable in clinical field. However, whether the common neoantigens can be identified in CRC is unknown. Combining the somatic mutations data from 321 CRC patients with a filter standard and 7 predicted algorithms, we screened and obtained 25 HLA-A*1101-restricted common neoantigens with a high binding affinity (IC50<50 nmol/L) and presentation score (>0.90). Besides the positive epitope KRAS_G12V8-16, 11 out of 25 common neoantigens specifically induced in vitro pre- stimulated cytotoxic lymphocyte (CTL) to secrete interferon gamma (IFN-γ). Moreover, combining cell-sorting technology and single-cell RNA sequencing, the immune repertoire profiles of C1orf170_S418G413-421 and KRAS_G12V8-16-specific CTL were analyzed and validated. Their related T-cell receptor engineered T cell (TCR-T) cells could also recognize the neoantigens and secrete IFN-γ. Hence, we have established a method to screen for common neoantigens with immunogenicity in CRC based on the public somatic mutation library. It can provide essential peptide and TCR information for immunotherapies, such as peptides, dendritic cells (DC) vaccines, TCR-like antibodies, TCR-T, etc., for the CRC and other cancers, which has practical application value in the clinics.

Alexithymia and Alcohol Dependence: The Roles of Negative Mood and Alcohol Craving.

Background: Alexithymia is a personality trait associated with emotion regulation difficulties. Up to 67% of alcohol-dependent patients in treatment have alexithymia. Objectives: The objective of this study was to investigate the direct and indirect effects of alexithymia, negative mood (stress, anxiety, and depression) and alcohol craving on alcohol dependence severity. Methods: Three hundred and fifty-five outpatients (mean age = 38.70, SD = 11.00, 244 males, range 18-71 years) undergoing Cognitive-Behavioral Therapy for alcohol dependence completed the Toronto Alexithymia Scale (TAS-20), Depression Anxiety Stress Scales (DASS-21), Obsessive Compulsive Drinking Scale (OCDS), and Alcohol Use Disorders Identification Test (AUDIT) prior to the first treatment session. Results: Alexithymia had an indirect effect on alcohol dependence severity, via both negative mood and alcohol craving (b = 0.03, seb = 0.008, 95% CI: 0.02-0.05). An indirect effect of negative mood on alcohol dependence via alcohol craving was also observed (b = 0.12, seb = 0.03, 95% CI: 0.07-0.16). Conclusions/importance: Alexithymia worked through negative mood and alcohol craving leading to increased alcohol dependence severity, indicating that craving had an indirect effect on the relationship between alexithymia and alcohol dependence severity. Targeting alcohol craving and negative mood for alcohol-dependent patients with alexithymia seems warranted.

Physicochemical Properties and Intestinal Health Promoting Water-Insoluble Fiber Enriched Fraction Prepared from Blanched Vegetable Soybean Pod Hulls.

Different methods can be used to change the fiber compositions of food, and they consequently affect the physicochemical properties and physiological activities. The present study compared the effects of a blanching treatment on the physicochemical properties of water-insoluble fiber enriched fraction (WIFF) from three varieties of vegetable soybean pod hulls (tea vegetable soybean pod hull, TVSPH; black vegetable soybean pod hull, BVSPH; 305 vegetable soybean pod hulls, 305VSPH) and evaluated their effects on intestinal health in hamsters. Blanching may increase the soluble dietary fiber (SDF) content of WIFF in the 305VSPH variety by solubilizing cell wall components and releasing water-soluble sugars. Thus, the WIFF in the 305VSPH variety after blanching may be composed of cellulose and pectic substances. The WIFF of the blanched 305VSPH (B-305VSPH) variety exhibited the highest physicochemical properties, such as a water-retention capacity (11.7 g/g), oil-holding capacity (9.34 g/g), swelling property (10.8 mL/g), solubility (12.2%), and cation-exchange capacity (221 meq/kg), of the three varieties examined. The supplementation of B-305VSPH WIFF in the diet resulted in significantly (p < 0.05) lower cecal and fecal ammonia; activities of fecal ß-d-glucosidase, ß-d-glucuronidase, mucinase, and urease; as well as higher cecal total short-chain fatty acids relative to other diets. In addition, microbial analysis suggested that fecal bifidobacteria growth was enhanced by the consumption of B-305VSPH WIFF. Therefore, B-305VSPH WIFF may be applicable as a potential functional ingredient in the food industry for the improvement of intestinal health.

[The Clinical Study of Comorbidities and Systemic Inflammation in COPD].

OBJECTIVE: To assess the association between chronic obstructive pulmonary disease (COPD) comorbidities and clinical characteristics, and to explore the inflammation mechanism. METHODS: 220 stable COPD patients were included. Clinical characteristics and comorbidities were recorded, and blood samples were collected. The relationship among the number and type of comorbidities, Charlson comorbidity index (CCI), clinical characteristics and the levels of plasma inflammatory markers [interleukin (IL)-6, high sensitivity C-reaction protein (hs-CRP), tumor necrosis factor-α (TNF-α), IL-8] were studied. RESULTS: The top five comorbidities were hypertension, metabolic syndrome and diabetes osteoporosis, bronchiectasis and peripheral vascular diseases. The level of plasma IL-6 was greater in higher CCI score (≥4) group compared with lower CCI score (<4) group ( P=0.011). Levels of IL-6 and IL-8 and the number of hospitalization in prior year were positively correlated with CCI and age adjusted CCI (r<0.03, P<0.05). There was a correlation between the COPD comorbidities and systemic inflammatory response (r<0.3, P<0.05). CONCLUSION: Patients with a higher CCI score had more severe symptoms, functional impairment and higher level of inflammatory factors and high frequency of hospital admission due to acute exacerbation. The mechanism by which COPD may play a role in systemic inflammatory response deserves further study.

Optimization of the extrusion process for preparation of soluble dietary fiber-enriched calamondin pomace and its influence on the properties of bread.

Calamondin pomace is a by-product obtained after calamondin juice extraction. The effects of extrusion variables on the soluble dietary fiber (SDF) of calamondin pomace were investigated by response surface methodology. Bread samples with different contents of extruded calamondin pomace (ECP) additive were produced and their textural and sensory properties evaluated. The optimal conditions for the extrusion of calamondin pomace were found to be a barrel temperature of 129 °C, feed moisture of 16%, and a screw speed of 298 rpm. The results revealed that extrusion increased the SDF of the calamondin pomace because the redistribution of insoluble dietary fiber formed SDF. A monosaccharide profile indicated that total dietary fiber in calamondin pomace processed by extrusion contained a high content of uronic acid and arabinose and a low amount of glucose, suggesting the presence of pectic polysaccharide and trace amounts of cellulose and hemicellulose. Increasing the ECP content decreased the specific volume and altered the textural properties, such as the hardness, gumminess and chewiness of the bread, and the bread became darker and redder in appearance. Sensory evaluation indicated that bread with 5% ECP content had good overall acceptability. Thus, extrusion of calamondin pomace can effectively increase the SDF content and resulting ECP can be used to produce SDF-enriched breads with sensory acceptability.

Analysis of the Clinical Characteristics, Management, and Causes of Death in Patients with ST-Segment Elevation Myocardial Infarction Treated With Primary Percutaneous Coronary Intervention from 2005 to 2014.

It is unknown whether there has been any change in the causes of death for acute ST-segment elevation myocardial infarction (STEMI) in the era of aggressive reperfusion. We analyzed the direct causes of in-hospital death in patients with STEMI treated with primary percutaneous coronary intervention (PCI) in a tertiary referral center over the past 10 years.We retrospectively analyzed 878 STEMI patients treated with primary PCI in our hospital between January 2005 and December 2014. There were no significant changes in the age and sex of patients, but the prevalence of hypertension and smoking decreased. STEMI severity increased with more patients in Killip classification > 2. The number of out-ofhospital cardiac arrest events also increased over the 10 years. Symptom onset-to-door time did not change in the 10year study period. The care quality was improved with shorter door-to-balloon time for primary PCI and increased use of dual antiplatelet therapy. The all-cause in-hospital mortality was 9.1%, which did not vary over the 10 years. Multivariable analysis showed that Killip classification > 2 was the most important determinant of death. Cardiogenic shock was the major cause of cardiovascular death. There was an increase in non-cardiovascular causes of death in the most recent 3 years, with infection being a major problem.Despite improvement in care quality for STEMI, the in-hospital mortality did not decrease in this tertiary referral center over these 10 years due to increased disease severity and non-cardiovascular causes of death.

Risk factors for ventilator-associated pneumonia in the neonatal intensive care unit: a meta-analysis of observational studies.

UNLABELLED: Ventilator-associated pneumonia (VAP) is a common and serious problem among mechanically ventilated patients in intensive care units (ICU), especially for the newborn. However, limited literatures have been reviewed to synthesize the finding of previous papers to investigate the risk factors for VAP although it has been a serious complication of mechanical ventilation (MV) with a high morbidity and mortality in the newborn. We performed this meta-analysis to extend previous knowledge for developing VAP prevention strategies by identifying the potential risk factors related to VAP in the neonatal intensive care unit (NICU). The relevant literatures published up to July 2013 were searched in the databases of PubMed, Cochrane Central Register of Controlled Trials, Embase, and Web of Science. Three reviewers screened those literatures and extracted data according to the inclusion and exclusion criteria independently. A total of eight studies including 370 cases and 1,071 controls were identified. Ten risk factors were found to be related to neonatal VAP which were listed as follows in order by odds ratios (ORs): length of stay in NICU (OR 23.45), reintubation (OR 9.18), enteral feeding (OR 5.59), mechanical ventilation (OR 4.04), transfusion (OR 3.32), low birth weight (OR 3.16), premature infants (OR 2.66), parenteral nutrition (OR 2.30), bronchopulmonary dysplasia (OR 2.21), and tracheal intubation (OR 1.12). CONCLUSION: We identified ten variables as independent risk factors for the development of VAP: length of stay in NICU, reintubation, enteral feeding, mechanical ventilation, transfusion, low birth weight, premature infants, parenteral nutrition, bronchopulmonary dysplasia, and tracheal intubation. Due to several limitations in the present study, further large and well-designed studies are needed to confirm the conclusion.

The impact of index futures crash risk on bitcoin futures returns and volatility.

This study examines the relationship between E-mini S&P 500 futures' crash risk and Bitcoin futures' returns and volatility using data from 2017 to 2021. While E-mini S&P 500's crash risk doesn't significantly influence Bitcoin returns, it correlates with its volatility, especially during events like the COVID-19 pandemic and U.S. elections. Furthermore, as global and emerging market indices rise, Bitcoin futures volatility decreases, suggesting its role as a hedging tool. These findings are pivotal for investors aiming to construct informed trading strategies, leverage Bitcoin futures as a hedging asset during economic instability, and keep tabs on traditional market indicators like E-mini S&P 500 crash risk for anticipating fluctuations in Bitcoin futures.
