A novel scoring system combining Modified Early Warning Score with biomarkers of monocyte distribution width, white blood cell counts, and neutrophil-to-lymphocyte ratio to improve early sepsis prediction in older adults.

OBJECTIVES: This study aims to investigate whether combining scoring systems with monocyte distribution width (MDW) improves early sepsis detection in older adults in the emergency department (ED). METHODS: In this prospective observational study, we enrolled older adults aged ≥60 years who presented with confirmed infectious diseases to the ED. Three scoring systems-namely quick sepsis-related organ failure assessment (qSOFA), Modified Early Warning Score (MEWS), and National Early Warning Score (NEWS), and biomarkers including MDW, neutrophil-to-lymphocyte ratio (NLR), and C-reactive protein (CRP), were assessed in the ED. Logistic regression models were used to construct sepsis prediction models. RESULTS: After propensity score matching, we included 522 and 2088 patients with and without sepsis in our analysis from January 1, 2020, to September 30, 2021. NEWS ≥5 and MEWS ≥3 exhibited a moderate-to-high sensitivity and a low specificity for sepsis, whereas qSOFA score ≥2 demonstrated a low sensitivity and a high specificity. When combined with biomarkers, the NEWS-based, the MEWS-based, and the qSOFA-based models exhibited improved diagnostic accuracy for sepsis detection without CRP inclusion (c-statistics=0.842, 0.842, and 0.826, respectively). Of the three models, MEWS ≥3 with white blood cell (WBC) count ≥11 × 109/L, NLR ≥8, and MDW ≥20 demonstrated the highest diagnostic accuracy in all age subgroups (c-statistics=0.886, 0.825, and 0.822 in patients aged 60-74, 75-89, and 90-109 years, respectively). CONCLUSIONS: Our novel scoring system combining MEWS with WBC, NLR, and MDW effectively detected sepsis in older adults.

Application of Artificial Neural Network Models to Differentiate Between Complicated and Uncomplicated Acute Appendicitis.

Preoperative prediction of complicated appendicitis is challenging, and many clinical tools are developed to predict complicated appendicitis. This study evaluated whether a supervised learning method can recognize complicated appendicitis in emergency department (ED). Consecutive patients with acute appendicitis presenting to the ED were enrolled and included into training and testing datasets at a ratio of 70:30. The multilayer perceptron artificial neural network (ANN) models were trained to perform binary outcome classification between uncomplicated and complicated acute appendicitis. Measures of sensitivity, specificity, positive and negative likelihood ratio (LR + and LR-), and a c statistic of a receiver of operating characteristic curve were used to evaluate an ANN model. The simplest ANN model by Bröker et al. including the C-reactive protein (CRP) and symptom duration as variables achieved a c statistic value of 0.894. The ANN models developed by Avanesov et al. including symptom duration, appendiceal diameter, periappendiceal fluid, extraluminal air, and abscess as variables attained a high diagnostic performance (a c statistic value of 0.949) and good efficiency (sensitivity of 78.6%, specificity of 94.5%, LR + of 14.29, LR- of 0.23 in the testing dataset); and our own model by H.A. Lin et al. including the CRP level, neutrophil-to-lymphocyte ratio, fat-stranding sign, appendicolith, and ascites exhibited high accuracy (c statistic of 0.950) and outstanding efficiency (sensitivity of 85.7%, specificity of 91.7%, LR + of 10.36, LR- of 0.16 in the testing dataset). The ANN models developed by Avanesov et al. and H.A. Lin et al. developed model exhibited a high diagnostic performance.

Diagnostic test accuracy of pretreatment collateral score in predicting stroke outcomes after intra-arterial endovascular thrombectomy: a meta-analysis in DSA and CTA.

OBJECTIVES: This study compared the diagnostic accuracy of pretreatment circulation collateral scoring (CS) system using digital subtraction angiography (DSA) and computed tomography angiography (CTA) in predicting favorable functional outcome (FFO) after intra-arterial endovascular thrombectomy (IA-EVT). Subgroup analysis characterizing scoring systems within each category was additionally conducted. MATERIALS AND METHODS: We performed a diagnostic meta-analysis to assess the sensitivity and specificity of each CS system by using DSA and CTA, respectively. The hierarchical summary receiver operating characteristic curve (HSROC) models were used to estimate the diagnostic odds ratio (DOR) and area under the curve (AUC). The Bayes theorem was employed to determine posttest probability (PTP). RESULTS: In total, 14 and 21 studies were assessed with DSA and CTA, respectively. In DSA, the pooled sensitivity and specificity were 0.72 (95% CI, 0.63-0.79) and 0.61 (0.53-0.68), respectively, and in the HSROC model, the DOR was 3.94 (2.71-5.73), and the AUC was 0.71 (90.67-0.75). CTA revealed a pooled sensitivity and specificity of 0.74 (0.64-0.82) and 0.53 (0.44-0.62), respectively, and in the HSROC model, the DOR was 3.17 (2.34-4.50), and the AUC was 0.67 (0.63-0.71). With a pretest probability of 26.3%, the CS in DSA and CTA exhibited limited increase of PTPs of 39% and 36%, respectively, in detecting the FFO on day 90. CONCLUSION: DSA and CTA have comparable accuracy and are limited in predicting the functional outcome. The collateral score systems assessed with DSA and CTA were more suitable for screening than diagnosis for patients before IA-EVT. KEY POINTS: • Our study revealed the differences of various scoring systems for assessing collateral status. • DSA and CTA have comparable accuracy, but both imaging modalities played relatively limited roles in predicting functional outcome on day 90. • The collateral score systems assessed with DSA and CTA were more suitable for screening than diagnosis for patients before IA-EVT.

Monocyte Distribution Width in Children With Systemic Inflammatory Response: Retrospective Cohort Examining Association With Early Sepsis.

OBJECTIVES: To investigate the association between increased monocyte distribution width (MDW) and pediatric sepsis in the emergency department (ED). DESIGN: Retrospective cohort study. SETTING: A single academic hospital study. PATIENTS: Patients from birth to the age of 18 years who presented at the ED of an academic hospital with systemic inflammatory response syndrome (SIRS) were consecutively enrolled. Sepsis was diagnosed using the International Pediatric Surviving Sepsis Campaign criteria. INTERVENTIONS: Antibiotic treatment was administrated once infection was suspected. MEASUREMENTS AND MAIN RESULTS: Routine complete blood cell count, neutrophil-to-lymphocyte ratio (NLR), and MDW, a new inflammatory biomarker, were evaluated in the ED. Logistic regression models were used to explore associations with early pediatric sepsis. We included 201 patients with sepsis and 1,050 without sepsis. In the multivariable model, MDW greater than 23 U (odds ratio [OR], 4.97; 95% CI, 3.42-7.22; p < 0.0001), NLR greater than 6 (OR, 2.06; 95% CI, 1.43-2.94; p = 0.0001), WBC greater than 11,000 cells/µL (OR, 6.52; 95% CI, 4.45-9.53; p < 0.0001), and the SIRS score (OR, 3.42; 95% CI, 2.57-4.55; p < 0.0001) were associated with pediatric sepsis. In subgroup analysis, MDW greater than 23 U remained significantly associated with sepsis for children 6-12 years old (OR, 6.76; 95% CI, 2.60-17.57; p = 0.0001) and 13-18 years (OR, 17.49; 95% CI, 7.69-39.76; p = 0.0001) with an area under the receiver operating curve of 0.8-0.9. CONCLUSIONS: MDW greater than 23 U at presentation is associated with the early diagnosis of sepsis in children greater than or equal to 6 years old. This parameter should be considered as a stratification variable in studies of pediatric sepsis.

Statins and the risk of bleeding in patients taking dabigatran.

OBJECTIVES: Dabigatran etexilate is a direct thrombin inhibitor that clinicians increasingly prescribe to prevent stroke in patients with non-valvular atrial fibrillation (NVAF). Clinicians also commonly prescribe statins for primary and secondary prevention of cardiovascular diseases. Little is known about the bleeding risk in patients taking a statin and dabigatran together. The aim of this study was to evaluate the safety and persistence of dabigatran after co-medication with statins. MATERIALS AND METHODS: We performed a prospective, multicenter registry study of stroke patients with NVAF who initiated dabigatran therapy within 3 months after a clinically evident ischemic cerebrovascular event between 2013 and 2017. The main outcome measure was symptomatic bleeding after 90, 180, and 360 days. RESULTS: In total, 652 patients (336 statin users, 316 non-users) were followed for 1 year after dabigatran therapy. Cox multivariate analysis demonstrated that male sex, prior use of aspirin, and concurrent use of an antiarrhythmic drug were associated with a higher risk of bleeding at 360 days. After adjusting time-dependent covariates, statin users had a significantly lower bleeding risk (adjusted hazard ratio: 0.11, P < 0.001) than non-users. Kaplan-Meier analysis indicated that patients prescribed with statins had a higher rate of bleeding-free survival (P = 0.028). CONCLUSION: For secondary prevention of stroke in patients with NVAF who are taking dabigatran etexilate, co-prescription with a statin was associated with a lower risk of bleeding complications. Future research is needed to determine the pharmacological mechanism underlying this effect.

Postural Headaches Due to Cerebrospinal Fluid Leakage Through Subarachnoid-Pleural Fistula: A Case Report.

BACKGROUND: Postural headaches are commonly associated with spontaneous intracranial hypotension and cerebrospinal fluid (CSF) leakage from the spine. A subarachnoid-pleural fistula (SPF) is a very rare and serious type of CSF fistula that has mostly been reported following traumatic causes. CASE REPORT: Here, the case of a 36-year-old woman who suffered from postural headaches after chiropractic manipulation of her neck was reported. Brain and spinal magnetic resonance (MR) imaging showed brain sagging, a C7-T1 dural defect, and overt CSF leakage. Heavy T2-weighted MR myelography revealed paravertebral fluid collections, communicating with pleural effusions through bilateral SPFs. The postural headaches were relieved by 3 courses of epidural blood patches. DISCUSSIONS: From the patient's history, her severe SPFs were attributed to rupture of the spinal leptomeninges during vigorous chiropractic manipulation of her neck. Heavy T2-weighted MR myelography could delineate the route of SPFs and CSF leakages.

Near-infrared imaging system for nondestructive inspection of micro-crack in wafer through dicing tape.

Detection of wafer/die crack after the wafer dicing process is important for yield rate control prior to packaging. The traditional approach of microscopic examination is done after the dies are stripped from the dicing tape, and further crack propagation could result from this pick-and-place process. An on-tape crack inspection technique is proposed in this paper so that the crack from the dicing process can be clearly identified. The issues of seeing through the silicon substrate and the scattering at the dicing tape have been resolved, respectively, using a near-infrared wavelength of 1100 nm for illumination and using a feeding index matching liquid for filling the rough surface of the tape. Both the illumination and imaging optics of the inspection system have been designed and simulated with a ray-tracing program, and the prototype demonstrates the ability of seeing through the silicon substrate and dicing tape as well as detecting micro-crack down to 1.25 µm, whose resolution is sufficient for most applications of die crack inspection.

Bilateral Paramedian Thalamic Infarction Presenting as Status Epilepticus: A Case Report and Review of the Literatures.

PURPOSE: Occlusion of the artery of Percheron (AOP), a rare vascular variant of basilar artery branch, is presumed to cause bilateral paramedian thalamic infarction. We present a case of acute AOP infarction with status epilepticus. CASE REPORT: A 65-year-old woman had past history of hypertension, type 2 diabetes mellitus, and major depressive disorder. She was found to have altered mental status on awakening. She developed tonic convulsion and progressed to status epilepticus later. The brain magnetic resonance imaging (MRI) showed acute bilateral paramedian thalamic and interpeduncular mesencephalic infarction. The electroencephalography (EEG) showed continuous epileptiform discharges. After receiving antiplatelet and anticonvulsant agents, she regained her level of consciousness and has completely recovered to previous baseline. CONCLUSIONS: To our knowledge, this is the first case of AOP infarction presenting status epilepticus. Early recognition and treatment of seizure may reverse altered mental status in those patients.

ABCD2-I Score Predicts Unplanned Emergency Department Revisits within 72 Hours Due to Recurrent Acute Ischemic Stroke.

BACKGROUND: the ABCD2 score is valuable for predicting early stroke recurrence after a transient ischemic attack (TIA), and Doppler ultrasound can aid in expediting stroke triage. The study aimed to investigate whether combining the ABCD2 score with carotid duplex results can enhance the identification of early acute ischemic stroke after TIA. METHODS: we employed a retrospective cohort design for this study, enrolling patients diagnosed with TIA who were discharged from the emergency department (ED). The modified ABCD2-I (c50) score, which incorporates a Doppler ultrasound assessment of internal carotid artery stenosis > 50%, was used to evaluate the risk of acute ischemic stroke within 72 h. Patients were categorized into three risk groups: low risk (with ABCD2 and ABCD2-I scores = 0-4), moderate risk (ABCD2 score = 4-5 and ABCD2-I score = 5-7), and high risk (ABCD2 score = 6-7 and ABCD2-I score = 8-9). RESULTS: between 1 January 2014, and 31 December 2019, 1124 patients with new neurological deficits were screened, with 151 TIA patients discharged from the ED and included in the analysis. Cox proportional hazards analysis showed that patients in the high-risk group, as per the ABCD2-I (c50) score, were significantly associated with revisiting the ED within 72 h due to acute ischemic stroke (HR: 3.12, 95% CI: 1.31-7.41, p = 0.0102), while the ABCD2 alone did not show significant association (HR: 1.12, 95% CI: 0.57-2.22, p = 0.7427). CONCLUSION: ABCD2-I (c50) scores effectively predict early acute ischemic stroke presentations to the ED within 72 h after TIA.

Early Identification of Sepsis-Induced Acute Kidney Injury by Using Monocyte Distribution Width, Red-Blood-Cell Distribution, and Neutrophil-to-Lymphocyte Ratio.

Sepsis-induced acute kidney injury (AKI) is a common complication in patients with severe illness and leads to increased risks of mortality and chronic kidney disease. We investigated the association between monocyte distribution width (MDW), red-blood-cell volume distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR), sepsis-related organ-failure assessment (SOFA) score, mean arterial pressure (MAP), and other risk factors and sepsis-induced AKI in patients presenting to the emergency department (ED). This retrospective study, spanning 1 January 2020, to 30 November 2020, was conducted at a university-affiliated teaching hospital. Patients meeting the Sepsis-2 consensus criteria upon presentation to our ED were categorized into sepsis-induced AKI and non-AKI groups. Clinical parameters (i.e., initial SOFA score and MAP) and laboratory markers (i.e., MDW, RDW, and NLR) were measured upon ED admission. A logistic regression model was developed, with sepsis-induced AKI as the dependent variable and laboratory parameters as independent variables. Three multivariable logistic regression models were constructed. In Model 1, MDW, initial SOFA score, and MAP exhibited significant associations with sepsis-induced AKI (area under the curve [AUC]: 0.728, 95% confidence interval [CI]: 0.668-0.789). In Model 2, RDW, initial SOFA score, and MAP were significantly correlated with sepsis-induced AKI (AUC: 0.712, 95% CI: 0.651-0.774). In Model 3, NLR, initial SOFA score, and MAP were significantly correlated with sepsis-induced AKI (AUC: 0.719, 95% CI: 0.658-0.780). Our novel models, integrating MDW, RDW, and NLR with initial SOFA score and MAP, can assist with the identification of sepsis-induced AKI among patients with sepsis presenting to the ED.

Developmental Trajectories and Predictors of Incident Dementia among Elderly Taiwanese People: A 14-Year Longitudinal Study.

The aim of this study was to identify dementia trajectories and their associated predictors among elderly Taiwanese people over a 14-year period using a nationwide representative longitudinal study. This retrospective cohort study was performed using the National Health Insurance Research Database. Group-based trajectory modeling (GBTM) was used to distinguish the specific trajectory groups of incident dementia during 2000-2013. All 42,407 patients were classified by GBTM to identify the trajectory of incident dementia, which included high- (n = 11,637, 29.0%), moderate- (n = 19,036, 44.9%), and low-incidence (n = 11,734, 26.1%) groups. Those diagnosed with hypertension (adjusted odds ratio [aOR] = 1.43; 95% confidence interval [CI] = 1.35-1.52), stroke (aOR = 1.45, 95% CI = 1.31-1.60), coronary heart disease (aOR = 1.29, 95% CI = 1.19-1.39), heart failure (aOR = 1.62, 95% CI = 1.36-1.93), and chronic obstructive pulmonary disease (aOR = 1.10, 95% CI = 1.02-1.18) at baseline revealed tendencies to be classified into high-incidence groups in dementia risk. The results from a 14-year longitudinal study identified three distinct trajectories of incident dementia among elderly Taiwanese people: patients with cardiovascular disease risk factors and cardiovascular disease events tended to be classified into high-incidence dementia groups. Early detection and management of these associated risk factors in the elderly may prevent or delay the deterioration of cognitive decline.

Predictors of 72-h unscheduled return visits with admission in patients presenting to the emergency department with abdominal pain.

BACKGROUND: Unscheduled return visits (URVs) to the emergency department (ED) constitute a crucial indicator of patient care quality. OBJECTIVE: We aimed to analyze the clinical characteristics of patients who visited the ED with abdominal pain and to identify the risk of URVs with admission (URVAs) from URVs without admission (URVNAs). METHODS: This retrospective study included adult patients who visited the ED of Taipei Medical University Hospital because of abdominal pain and revisited in 72 h over a 5-year period (January 1, 2014, to December 31, 2018). Multivariable logistic regression analysis was employed to identify risk factors for URVAs and receiver operating characteristic (ROC) curve analysis was performed to determine the efficacy of variables predicting URVAs and the optimal cut-off points for the variables. In addition, a classification and regression tree (CART)-based scoring system was used for predicting risk of URVA. RESULTS: Of 702 eligible patients with URVs related to abdominal pain, 249 had URVAs (35.5%). In multivariable analysis, risk factors for URVAs during the index visit included execution of laboratory tests (yes vs no: adjusted odds ratio [AOR], 4.32; 95% CI 2.99-6.23), older age (≥ 40 vs < 40 years: AOR, 2.10; 95% CI 1.10-1.34), Level 1-2 triage scores (Levels 1-2 vs Levels 3-5: AOR, 2.30; 95% CI 1.26-4.19), and use of ≥ 2 analgesics (≥ 2 vs < 2: AOR, 2.90; 95% CI 1.58-5.30). ROC curve analysis results revealed the combination of these 4 above variables resulted in acceptable performance (area under curve: 0.716). The above 4 variables were used in the CART model to evaluate URVA propensity. CONCLUSIONS: Elder patients with abdominal pain who needed laboratory workup, had Level 1-2 triage scores, and received ≥ 2 doses of analgesics during their index visits to the ED had higher risk of URVAs.

Efficacy and safety of tirofiban in patients with acute ischemic stroke treated with endovascular thrombectomy: A frequentist and Bayesian meta-analysis.

BACKGROUND: Tirofiban is an antiplatelet treatment approved for acute coronary syndrome, but it has not been rigorously evaluated for efficacy and safety in patients with acute ischemic stroke (AIS) treated with endovascular thrombectomy (EVT). METHODS: Electronic databases were systematically searched for studies conducted from January 1, 2015, to July 31, 2021, that evaluated tirofiban administration for patients with AIS treated with EVT in comparison with control. Risk ratios (RRs) and confidence intervals (CIs) were estimated for favorable functional outcomes (FFOs), mortality, and symptomatic intracranial hemorrhage (SICH), each 90 days after AIS. Bayesian hierarchical modeling was performed to obtain posterior RR and its 95% highest posterior density (HPD) for validation. RESULTS: Compared with controls, tirofiban users exhibited increased FFOs (RR, 1.18; 95% CI, 1.08-1.30), decreased mortality (RR, 0.77; 95% CI, 0.64-0.92), and no difference in SICH (RR, 0.97; 95% CI, 0.77-1.23). Tirofiban users in the postbolus infusion subgroup exhibited increased FFOs (RR, 1.20; 95% CI, 1.07-1.35), decreased mortality (RR, 0.71; 95% CI, 0.58-0.88), and no increase in SICH (RR, 0.97; 95% CI, 0.72-1.29). The bolus-only subgroup showed no differences in FFO, mortality, or SICH between the tirofiban and control groups. Consistent results were obtained for posterior density of FFO (posterior RR, 1.20; 95% HPD, 1.06-1.34), mortality (posterior RR, 0.77; 95% HPD, 0.63-0.92), and SICH (posterior RR, 0.98; 95% HPD, 0.71-1.26). CONCLUSION: For patients with AIS treated with EVT, tirofiban improved FFOs, decreased mortality, and did not increase SICH compared with controls; postbolus infusion for administering tirofiban was more favored than the bolus-only regimen.

Recovered memory experience in a nonclinical sample is associated with dissociation rather than with aversive experiences.

Different hypotheses exist for the relationship among trauma, dissociation, and recovered memory. According to one view, recovered memory results from dissociation that a survivor adopts as a defense mechanism during a traumatizing event to avoid emotional pain. From this perspective, trauma is a necessary antecedent to relate dissociative symptoms with recovered memory. Another view emphasizes the characteristics of the victim, such as fantasy proneness and atypical cognitive operations. This alternate view holds that trauma is not necessary in relating dissociation to recovered memory. We tested these two hypotheses, measuring recovered memory, dissociative symptoms, childhood interpersonal adversity, and fantasy proneness in a nonclinical sample of college students. Our results showed a significant correlation between recovered memory and dissociative symptoms; the correlation cannot be accounted for by childhood interpersonal adversity, fantasy proneness, or absorption. Recovered events can be negative, neutral, or even positive. Trauma is not necessary in relating recovered memory to dissociative symptoms.

Quality of life and cognitive assessment in healthy older Asian people with early and moderate chronic kidney disease: The NAHSIT 2013-2016 and validation study.

BACKGROUND: Taiwan has the highest prevalence of chronic kidney disease (CKD). Impaired cognition and quality of life are significant phenomena in the late stages of CKD. We sought to obtain an overview and the attributable effect of impaired glomerular filtration on multiple domains in cognition and dimensions of quality of life for community-based healthy older adults in Taiwan. METHODS: The study was derived from the Nutrition and Health Survey in Taiwan (NAHSIT) 2013-2016, a nationwide cross-sectional study conducted to sample healthy, community-based older adults aged ≥65 years in Taiwan. Participants were categorized into four CKD groups: CKD stage 1, stage 2, stages 3a and 3b, and stages 4-5. The Mini-Mental State Examination (MMSE) and the QoL questionnaire derived from the 12-item Short Form Health Survey (SF-12) were measured. Generalized linear mixed models (GLMMs) and principal component regressions were employed for the analysis and validation, respectively. RESULTS: Participants with moderate CKD (stages 3a and 3b) showed deficits in global MMSE, domain orientation to time, calculation, complex commands, and role-physical and vitality in QoL questionnaires. In GLMMs, impaired eGFR per 30 mL/min/1.73 m² was associated with lower global MMSE scores (ß = -0.807, standard error [SE] = 0.235, P = 0.0007), domain orientation to time (ß = -0.155, SE = 0.047, P = 0.0011), calculation (ß = -0.338, SE = 0.109, P = 0.0020), complex commands (ß = -0.156, SE = 0.079, P = 0.0494), and role-physical (ß = -2.219, SE = 0.779, P = 0.0046) dimensions of QoL. CONCLUSIONS: Elderly Han Chinese adults with moderately impaired renal filtration could manifest cognitive deficits in orientation to time, calculation, and impaired quality of life in physical role functioning.

Effects of socioeconomic status on the control of hypertension in patients <65 and ≥65 years of age in Taiwan: a nationwide cross-sectional study.

OBJECTIVE: Implementation of National Health Insurance in 1995 improved the control of hypertension due to comprehensive coverage of medical costs for all residents in Taiwan. However, the role of individual socioeconomic status (iSES), namely, education and personal income, in awareness, treatmen, and control of blood pressure, has not been well studied in Taiwan. DESIGN: A nationwide cross-sectional survey was executed in this study. SETTING: A systematic, multistage sampling scheme from a nationwide cohort in Taiwan was adopted to select adult participants. Hypertension was defined as blood pressure ≥ 140/90 mm Hg or the use of antihypertensive medications. PARTICIPANTS: A total of 4599 subjects completed door-to-door household interviews and physical examinations. PRIMARY AND SECONDARY OUTCOME MEASURES: A summing z score of iSES was constructed by two domains of the iSES, namely, income and education, through which participants were classified into three SES levels. Logistic regression models were used to assess associations of awareness, treatment, and control in younger (<65 years) and older (≥65 years) participants with hypertension. RESULTS: Younger people in the highest tertile of iSES were less likely to be aware of their hypertension (OR: 0.48, 95% CI: 0.37 to 0.64, p<0.0001) or to have it treated (OR: 0.49, 95% CI 0.37 to 0.64, p<0.0001) but more likely to have their hypertension controlled (OR: 1.52, 95% CI 1.19 to 1.94, p=0.0009). We did not detect an association in people aged >65 years. CONCLUSION: Health education to improve awareness and treatment of hypertension should focus on younger people with higher iSES in Taiwan.

Association between GnRH analogue use and atopic diseases in patients with prostate cancer: A population-based retrospective cohort study.

PURPOSE: Gonadotropin-releasing hormone (GnRH) analogues reduce testosterone levels to castration levels in patients with prostate cancer. However, the role of testosterone in atopic diseases has remained undefined. We aimed to investigate this role. MATERIALS AND METHODS: This retrospective cohort study was conducted using the National Health Insurance Research Database (NHIRD). Patients with prostate cancer were categorized into two groups according to whether they received GnRH analogue treatment (study group I) or not (study group II), and men without prostate cancer and with no GnRH analogue use were defined to comprise the comparison group after their ages and index years were matched with group II. Cox proportional hazard models were used to assess the hazard ratio (HR) of atopic diseases. RESULTS: Group I, group II, and the comparison group comprised 663, 2,172, and 8,688 individuals, respectively. Group I had a significantly lower risk of atopic diseases (adjusted HR: 0.66, 95% CI, 0.49-0.89, p < 0.01) than did group II. A reduced risk of atopic diseases was found when GnRH analogues were prescribed for 2 months (adjusted HR 0.53, 95% CI, 0.29-0.97, p = 0.04) and 2-14 months (adjusted HR 0.66, 95% CI, 0.49-0.89, p = 0.007). No significant difference in the risk of atopic diseases between group II and the comparison group was observed. CONCLUSIONS: A decreased risk of atopic diseases was observed in patients with prostate cancer treated with GnRH analogues. Further studies are warranted to verify the association between testosterone levels and atopic diseases.

Fever, Tachypnea, and Monocyte Distribution Width Predicts Length of Stay for Patients with COVID-19: A Pioneer Study.

(1) Background: Our study investigated whether monocyte distribution width (MDW) could be used in emergency department (ED) settings as a predictor of prolonged length of stay (LOS) for patients with COVID-19. (2) Methods: A retrospective cohort study was conducted; patients presenting to the ED of an academic hospital with confirmed COVID-19 were enrolled. Multivariable logistic regression models were used to obtain the odds ratios (ORs) for predictors of an LOS of >14 days. A validation study for the association between MDW and cycle of threshold (Ct) value was performed. (3) Results: Fever > 38 °C (OR: 2.82, 95% CI, 1.13−7.02, p = 0.0259), tachypnea (OR: 4.76, 95% CI, 1.67−13.55, p = 0.0034), and MDW ≥ 21 (OR: 5.67, 95% CI, 1.19−27.10, p = 0.0269) were robust significant predictors of an LOS of >14 days. We developed a new scoring system in which patients were assigned 1 point for fever > 38 °C, 2 points for tachypnea > 20 breath/min, and 3 points for MDW ≥ 21. The optimal cutoff was a score of ≥2. MDW was negatively associated with Ct value (ß: −0.32 per day, standard error = 0.12, p = 0.0099). (4) Conclusions: Elevated MDW was associated with a prolonged LOS.
