Increased tissue expression of IL-31 in patients with psoriasis.

Psoriasis is a chronic inflammatory skin disease, and its pathogenesis remains unclear. Although many studies have demonstrated the role of serum interleukin-31 (IL-31) in psoriasis, only one study has examined histopathological expression in lesional skin. This study aimed to investigate the expression of IL-31 in skin biopsy specimens of psoriasis patients compared to healthy subjects and identify its possible correlation to disease severity and itch intensity. Psoriasis patients and healthy volunteers were recruited. Four-millimeter punch biopsy was performed at the lesional skin of psoriasis patients and normal skin of healthy subjects. Expression of IL-31 was measured by immunohistochemistry. Baseline characteristics, disease activity, itch intensity, and related laboratory results were collected. Twenty-six biopsy specimens of psoriasis patients and 10 tissue samples of healthy subjects were evaluated. Epidermal and dermal psoriasis lesions had significantly higher IL-31 expression compared to the healthy skin (P < 0.001). However, there was no significant difference in lesional expression of IL-31 by disease severity or itch intensity. Increased IL-31 expression in the lesions of psoriasis patients suggests the involvement of IL-31 in the pathogenesis of psoriasis.

Clinical predictive factors of coronary stenosis in patients with high­risk valvular heart disease who received diagnostic coronary angiography prior to cardiac valve surgery.

Valvular heart disease (VHD) may lead to morbidities and mortality due to heart failure or sudden death. Concomitant coronary artery disease (CAD) is a crucial condition that needs to be explored in patients with VHD prior to cardiac valve surgery as it may increase morbidity and mortality. Patient age >40 years and mitral regurgitation are key risk factors for CAD in patients with VHD. The present study aimed to identify clinical risk factors for coronary stenosis in patients with high-risk VHD. The retrospective cohort study recruited patients aged >40 years who received cardiac valve surgery and coronary angiogram prior to cardiac valve surgery. Clinical factors predictive of coronary stenosis were computed by logistic regression analysis. There were 533 patients; 114 patients (21.38%) had coronary stenosis. Four factors were positively associated with coronary stenosis including age, male sex, mitral regurgitation and hypertension, while two factors were negatively associated with coronary stenosis, namely estimated glomerular filtration rate and rheumatic heart disease. Hypertension had the highest adjusted odds ratio at 2.596, while rheumatic heart disease had the lowest adjusted odds ratio at 0.428. Patient age >55 years showed a sensitivity and specificity of coronary stenosis of 80.70 and 37.47%, respectively. Clinical factors predictive of coronary stenosis in patients with high-risk VHD were age >55 years, male sex, mitral regurgitation and hypertension, while a high estimated glomerular filtration rate and presence of rheumatic heart disease were protective factors.

Salivary trefoil factor family peptide 3 (TFF3) and flow rate in persons with and without obstructive sleep apnea: A preliminary study.

OBJECTIVES: Obstructive sleep apnea (OSA) is one of the most common chronic diseases. Trefoil factor family 3 (TFF3) peptides are secreted by major and minor salivary glands and may be involved in the pathogenesis of OSA. This study aimed to evaluate salivary TFF3 and flow rate between those with and without OSA. MATERIAL AND METHODS: This was a prospective experimental study that enrolled patients with OSA and non-OSA. Total unstimulated saliva was collected, the salivary flow rate was measured, and the TFF3 level was analyzed by using a modified sandwich enzyme-linked immunosorbent assay. Baseline characteristics, TFF3 level, and salivary flow rate were compared between both groups. Factors associated with the TFF3 level and flow rate were computed by using multivariate linear regression analysis. RESULTS: Twenty-eight participants were recruited in the study: 20 patients with OSA (71.42%) and 8 non-OSA as control. The TFF3 and salivary flow rates between both groups of non-OSA versus OSA were comparable (TFF3 non-OSA 61.06 vs. OSA 96.00 ng/mg; p = .276 and flow rate non-OSA 0.40 vs. OSA 0.35 mL/min; p = .320). Factors associated with the TFF3 level were neck circumference with a negative coefficient of -16.419 (p = .042). For the salivary flow rate, only age was a significant factor with the coefficient of -0.013 (p = .044). CONCLUSIONS: TFF3 and salivary flow rate were comparable between patients with OSA and non-OSA. The factor associated with TFF3 level was neck circumference, while age was negatively associated with the salivary flow rate in patients with OSA.

PIVKA-II or AFP has better diagnostic properties for hepatocellular carcinoma diagnosis in high-risk patients.

Background: Hepatocellular carcinoma (HCC) is a lethal cancer. Two biomarkers were used for HCC diagnosis including alpha-fetoprotein (AFP) and protein induced by vitamin K absence-II or antagonist (PIVKA-II). However, data on biomarkers and HCC diagnosis are not consistent. This study aimed to evaluate if PIVKA-II, AFP, or a combination of both biomarkers had the best diagnostic properties for HCC. Methods: This was a prospective study and enrolled patients 18 years or over with a high risk for HCC. AFP and PIVKA-II levels were calculated for HCC diagnosis. Diagnostic properties of both biomarkers were reported with sensitivity, specificity, and a receiver operating characteristic (ROC) curve. Results: There were 260 patients with high risk for HCC in this cohort. Of those, 219 patients were diagnosed with HCC: confirmed by biopsy in 7 patients (2.69%) and by imaging in the others. Median values of AFP and PIVKA-II were 56 ng/mL and 348 mAU/mL, respectively. PIVKA-II level of 40 mAU/mL had sensitivity of 80.80%, while AFP of 10 ng/mL had sensitivity of 75.80%. A combination of PIVKA-II at 100 mAU/mL or over and AFP of 11 ng/mL gave sensitivity of 60.30%. The ROC curve of PIVKA-II plus AFP was significantly higher than the AFP alone (0.855 vs. 0.796; p = 0.027), but not significantly different from the PIVKA-II alone (0.855 vs. 0.832; p = 0.130). Conclusion: PIVKA-II may have more diagnostic yield for HCC compared with AFP. It can be used alone without a combination with AFP.

Clinical Characteristics and Outcomes of Patients with Intracerebral Hemorrhage: Nonsurgical Versus Surgical Treatment.

Introduction: Primary intracerebral hemorrhage (ICH) is a stroke subtype with high morbidity and mortality. Surgical treatments for ICH may be one of the beneficial modalities. There are inconsistent clinical outcomes of surgical treatments in several randomized controlled trials. This study aimed to evaluate if surgical treatment can reduce mortality in patients with ICH in a real-world setting. Methods: This was a retrospective analytical study. The inclusion criteria were consecutive adult patients aged 18 years or over admitted to neurosurgery ward due to ICH, and indicated for surgical treatment according to the 2015 guideline for the management of spontaneous ICH. The outcomes of this study included mortality, length of stay, Barthel index, Glasgow Outcome Score (GOS), and Glasgow Coma Scale (GCS). Descriptive statistics were used to execute the differences between those who underwent and did not undergo surgical treatments. Factors associated with mortality were computed by multivariate logistic regression analysis. Results: There were 110 patients with ICH who met the study criteria. Of those, 34 (30.91%) patients underwent surgical treatment: mainly craniotomy (16 patients; 47.06%). The surgical treatment group had significantly higher proportions of large ICH of 30 mL or over (62.96% vs. 27.54%; P = 0.002) and intraventricular hemorrhage (70.59% vs. 46.05%; P = 0.023) than the nonsurgical treatment group. However, both groups had comparable outcomes in terms of mortality, length of stay, Barthel index, GOS, and GCS. The mortality rate in the surgery group was 47.06%, whereas the nonsurgery group had a mortality rate of 39.47 (P = 0.532). There were three independent factors associated with mortality, including age, GCS, and intraventricular hemorrhage. The adjusted odds ratio (95% confidence interval) of these factors was 1.06 (1.02-1.12), 5.42 (1.48-19.81), and 5.30 (1.65-17.01). Intraventricular hemorrhage was more common in the elderly than in the nonelderly group (66.00% vs. 43.33%; P = 0.022). Conclusions: Surgical treatment may not be beneficial in patients with severe ICH, particularly with intraventricular hemorrhage, large ICH volume, or low GCS. Elderly patients with ICH may also have high mortality if intraventricular hemorrhage is present.

Clinical factors predictive of Gram-negative bloodstream infection at the Emergency Department.

Introduction: Bloodstream infection is a common condition at the Emergency Department (ED). Appropriate antibiotic therapy is also crucial for patients with bloodstream infection particularly at the ED. This study therefore aimed to find clinical factors predictive of types of bacterial pathogens in bloodstream infection patients presenting at the ED focused on Gram-negative bacterial infections. Methods: This was a retrospective study. The inclusion criteria were adult patients who were suspected for bloodstream infection defined by blood culture collection presenting at the ED and intravenous antibiotics were initiated during the ED visits. The study period was between January 1st, 2016 and December 31st, 2018. Clinical data of the eligible patients were retrieved from the ED database. Factors associated with Gram-negative infection were calculated by logistic regression analysis. Results: There were 727 patients at the ED who had positive blood culture for bacteria. Of those, 504 patients (69.33%) had positive blood culture for Gram-negative bacteria. There were three independent factors for Gram-negative infection including sex, solid organ malignancy, and body temperature. The highest adjusted odds ratio (95% confidence interval) was 2.004 (1.330, 3.020) for solid organ malignancy. Conclusions: Gram-negative bacterial infection was more prominent than Gram-positive bacterial infection in patients presenting at the ED (69.33%). Solid organ malignancy, being female, and a high body temperature were independent factors of Gram-negative bacterial infection.

Factors Associated With Refractoriness to an Up to Fourfold Dosage of Antihistamines in Isolated Chronic Spontaneous Urticaria.

BACKGROUND: Chronic spontaneous urticaria (CSU) is a common skin disease and has a significant impact on patients' quality of life. The aim of treatment is complete symptom control. AIM: To identify potential factors associated with antihistamine-refractory isolated CSU and to determine the factors that predict response to second-generation H1 antihistamines at dosages from one- to fourfold. METHODS: We conducted a retrospective cohort study, which included adult patients diagnosed with isolated CSU and had complete symptom control. Clinical and laboratory findings were compared between the patients who were responsive to second-generation H1 antihistamines (< fourfold) and those who were refractory to a fourfold dose. Clinical and laboratory data were compared by dosage in the antihistamine-responsive group. RESULTS: There were 182 isolated CSU patients who met the study criteria, of whom 150 (82.4%) were responsive to treatment with up to a fourfold dose of second-generation H1 antihistamines, while 32 (17.6%) were refractory. In univariate analysis, age at onset, body mass index, baseline Urticaria Activity Score-7 (UAS7), white blood cell count, total neutrophil count, neutrophil-lymphocyte ratio, platelet count, and new generation antihistamines were significantly higher in the antihistamine-refractory group. According to multivariate analysis, baseline UAS7 was the only independent factor associated with antihistamine-refractory isolated CSU (odds ratio 1.14, 95% CI 1.01-1.28, P = .03). In the antihistamine-responsive group, white blood cell count tended to predict response to antihistamine treatment (P < .001, 0.04, 0.34 between onefold and twofold, twofold and threefold, and threefold and fourfold, respectively). CONCLUSION: Baseline UAS7 was an independent factor associated with antihistamine-refractory isolated CSU.

A surveillance for hepatitis C virus infection in northeastern, Thailand: a 10-year cohort.

Introduction: Hepatitis C virus (HCV) infection is an infection that may lead to cirrhosis and hepatocellular carcinoma. Most patients with HCV infection are asymptomatic. The previous study conducted in age group of 30-64 years and in two provinces. Additionally, most surveillance studies conducted in a point period; not longitudinally. This study aimed to evaluate HCV infection rate in all age groups in the northeastern, Thailand in a longitudinal fashion. Methods: This was a surveillance study conducted in 20 provinces of northeastern, Thailand. The study period was between July 2010 and November 2019. During the surveillance, demographic data of participants were collected. HCV screening test was performed in each participant by using a rapid point-of-care assay. Rates of HCV infection in each province and in overall were calculated. Results: During the surveillance period, there were 31,855 subjects who participated the project. Of those, 1,285 subjects (4.037%) were tested positive for HCV infection (Tab. I). The HCV infection rate was highest in 2011 (8.98%): ranges 1.28 to 9.59%. The age group of over 50 years had 690 subjects with HCV infection (5.45%) out of 12,660 subjected tested in this age group. There was significant different among age groups (p < 0.001) and difference of age over 30 years and sex (p 0.043). Conclusions: This longitudinal surveillance showed that HCV infection rates in northeastern, Thailand were varied across the provinces with the highest rate of 9.59%. The HCV infection should be aware in male with age over 30 years.

A meta-analysis to identify factors associated with CPAP machine purchasing in patients with obstructive sleep apnea.

Obstructive sleep apnea (OSA) is a common disease and related to several cardiovascular diseases. Treatment with a continuous positive airway pressure (CPAP) machine is effective. However, not all patients with OSA purchase a CPAP machine for personal use. Previous studies showed different predictors of CPAP machine purchasing in patients with OSA. The present study aimed to summarize and identify predictors of CPAP purchasing using meta-analysis. The study was conducted using factors associated with CPAP purchasing in patients with OSA. The types of studies conducted in adult patients with OSA included: Randomized controlled trials, observational studies or descriptive studies comparing factors between those who purchased CPAP and those who did not. A total of five databases, including PubMed, Central database, Scopus, CINAHL Plus and Web of Science, were searched, and the final search was performed on February 8, 2021. Predictors for CPAP purchasing were determined. There were 598 articles from five databases, which met the inclusion criteria. After duplicated article removal, 390 articles were included in the screening process. There were 12 eligible articles for full text evaluation, and of those, eight studies met the study criteria with 1,605 patients from four countries. There were 11 variables that were available for a comparison between those who purchased the CPAP machine and those who did not, and six factors were different between the two groups: Age, years of education, income, smoking, Epworth Sleepiness Scale (ESS) score and apnea hypopnea index/respiratory disturbance index (AHI/RDI). The AHI/RDI was significantly different between the two groups, with the highest mean difference of 10.40 events/h (95% CI, 4.95-15.86). Patients who purchased CPAP were older (1.11 years), had more years of education (0.93 years), smoked more (1.15 pack/year), and had both higher ESS (0.61) and AHI/RDI (10.40) than those who did not purchase CPAP. Additionally, those who purchased CPAP had a 1.47 times higher income than those who did not. In conclusion, specific personal customer and clinical factors were related to the decision of CPAP purchase in patients with OSA.

Clinical versus radiographical factors associated with hepatocellular carcinoma diagnosis in high-risk patients: sizes matter.

Aim: This study aimed to evaluate if clinical or radiographic findings can be used for hepatocellular carcinoma (HCC) diagnosis particularly in high-risk patients. Methods: This was a prospective study and evaluated factors associated with HCC. Results: There were 260 patients met the study criteria: 219 patients (84.23%) were HCC. Two factors significantly associated with HCC: portal vein invasion and the largest mass size. The cutoff point for the largest mass size of 2 cm or over gave sensitivity and specificity for HCC of 83.56 and 87.80%, respectively. Conclusion: Portal vein invasion and the largest liver mass of 2 cm or over may be diagnostic factors for HCC in high-risk patients, while clinical factors were not suggestive for HCC.

Clinical factors predictive of recurrent febrile neutropenia in adult patients with acute leukemia.

Febrile neutropenia (FN) is considered an oncologic emergency in acute leukemia. There were 250 FN events in 124 hospitalized patients with hematologic malignancy. These data imply that two FN events may occur per patient, yet data on the prevalence, risk factors, and outcomes of recurrent FN in adult patients with leukemia are limited. A retrospective cohort study was conducted that enrolled adult patients diagnosed with acute leukemia who developed FN. The eligible patients were categorized as with or without recurrent FN. A stepwise, multivariate logistic regression analysis was performed to identify predictors of recurrent FN. A total of 203 patients met the study criteria; of these, 46 (22.66%) had recurrent FN, and this group had a median of three recurrent FN emergencies. After adjusted, three independent factors remained in the final model including ALL, FN at admission, and treatment with idarubicin (3 days) and cytarabine (7 days). The three factors were positively associated with recurrent FN with adjusted odds ratios of 6.253, 4.068, and 10.757, respectively. No significant differences were found between the two groups in terms of other sources of infection, other pathogens, ICU stay, hospital stay, and mortality. ALL and FN at admission and treatment with idarubicin (3 days) and cytarabine (7 days) were associated with recurrent FN in acute leukemia patients with FN. Clinical outcomes for patients with or without recurrent FN were mostly comparable; however, due to its small sample size, further studies are required to confirm the results of this study.

Oxygen saturation is associated with recurrent primary spontaneous pneumothorax treated by intercostal chest drainage.

BACKGROUND: Primary spontaneous pneumothorax (PSP) is a condition that may lead to acute chest pain or dyspnea on exertion. Treatment with an intercostal chest drainage (ICD) is warranted. There is limited data on risk factors of recurrent PSP in patients treated with the ICD alone. This study aimed to evaluate risk factors of recurrent PSP in patients with PSP and treated with the ICD. METHODS: This was a retrospective study and enrolled patients diagnosed as PSP and treated with an ICD. Eligible patients were divided into two groups by evidence of recurrent PSP. Baseline characteristics, physical signs, laboratory results, and duration of ICD treatment were studied and recorded from medical charts. Factors associated with recurrent PSP were computed by using multivariate logistic regression analysis. RESULTS: There were 80 patients met the study criteria. Of those, 21 patients (26.3%) had recurrent PSP. Of those, 21 patients (26.3%) had recurrent PSP. There were eight factors in the final model for recurrent PSP. Only oxygen saturation at the time of diagnosis was independently associated with recurrent PSP. The adjusted odds ratio (95% confident interval) was 0.57 (0.34, 0.96). A cut point of 96% of oxygen saturation gave sensitivity of recurrent PSP of 80.95%. CONCLUSION: The prevalence of recurrent PSP was 26.3% in patients with PSP and treated with the ICD. Initial oxygen saturation may be an indicator for recurrent PSP.

Surveillance for hepatitis B virus seroprevalence nearly 30 years after the implementation of a national vaccination program.

INTRODUCTION: Hepatitis B virus (HBV) infection is associated with cirrhosis and hepatocellular carcinoma. Vaccination is one aspect of public health policy aimed at eliminating HBV infection. After the implementation of an HBV vaccination program for newborns in Thailand, the estimated residual infection rate was 3.5%. However, that study was conducted in only 5,964 participants in seven provinces and only 22 years after the start of the campaign. This study aimed to evaluate the HBV seroprevalence rate in Thailand in larger sample size and a longer duration after program implementation using HBV surveillance. METHODS: This was a surveillance study conducted in 20 provinces in northeast Thailand. The study period was between July 2010 and November 2019. Rates of HBV seroprevalence in each province and overall were calculated. Participants were divided into two groups: those vaccinated under the national campaign and those who were not. Participants aged 0-20 years were used as references, while other age groups (intervals of 10 years) were comparators. Residual HBV seroprevalence after the vaccination program was calculated with odds ratio for HBV seroprevalence in each age group. RESULTS: There were 31,855 subjects who participated in the project. Of those, 1,805 (5.7%) had HBV. The HBV seroprevalence rate in the national HBV vaccination group was significantly lower than that in those not vaccinated under the national program (1.0% vs 5.9%; p<0.001). Seroprevalence was 1.0% in participants ≤20 years of age. Participants 31-40 years of age had the highest odds ratio (10.41), followed those 21-30 years of age (7.42). CONCLUSIONS: This real-world surveillance study showed that residual HBV infection was 1.0% after nearly 30 years of nationwide HBV vaccination.

What are the strongest indicators of intracerebral hemorrhage in mild traumatic brain injury?

BACKGROUND: Although there are eight factors known to indicate a high risk of intracranial hemorrhage (ICH) in mild traumatic brain injury (TBI), identification of the strongest of these factors may optimize the utility of brain CT in clinical practice. This study aimed to evaluate the predictors of ICH based on baseline characteristics/mode of injury, indications for brain CT, and a combination of both to determine the strongest indicator. METHODS: This was a descriptive, retrospective, analytical study. The inclusion criteria were diagnosis of mild TBI, high risk of ICH, and having undergone a CT scan of the brain. The outcome of the study was any type of ICH. Stepwise logistic regression analysis was used to find the strongest predictors according to three models: (1) injury pattern and baseline characteristics, (2) indications for CT scan of the brain, and (3) a combination of models 1 and 2. RESULTS: There were 100 patients determined to be at risk of ICH based on indications for CT of the brain in patients with acute head injury. Of these, 24 (24.00%) had ICH. Model 1 found that injury due to motor vehicle crash was a significant predictor of ICH, with an adjusted OR (95% CI) of 11.53 (3.05 to 43.58). Models 2 and 3 showed Glasgow Coma Scale (GCS) score of 13 to 14 after 2 hours of observation and open skull or base of skull fracture to be independent predictors, with adjusted OR (95% CI) of 11.77 (1.32 to 104.96) and 5.88 (1.08 to 31.99) according to model 2. DISCUSSION: Open skull or base of skull fracture and GCS score of 13 to 14 after 2 hours of observation were the two strongest predictors of ICH in mild TBI. LEVEL OF EVIDENCE: III.

Clinical factors predictive of mortality in acute leukemia patients with febrile neutropenia.

BACKGROUND: Acute leukemia is mainly treated with chemotherapy leading to febrile neutropenia (FN). There is limited data on clinical factors predictive of mortality in adults with acute leukemia and FN. METHODS: This was a retrospective cohort study and enrolled adult patients, diagnosed as acute leukemia, and developed FN. The eligible patients were admitted and followed up with mortality as the primary outcome. A stepwise, multivariate logistic regression analysis was used to find predictors for mortality. RESULTS: There were 203 patients met the study criteria. Of those, 14 patients died (6.89%). AML was the most common type of acute leukemia with FN (64.04%). There were five remaining factors in the final model: AML, FN at admission, prolong broad spectrum antibiotics, lower respiratory tract infection, and Aspergillosis. Only lower respiratory tract infection was significant with adjusted odds ratio of 7.794 (95% CI of 1.549, 39.212). The Hosmer-Lemeshow Chi square was 2.74 (p value 0.907). The lower respiratory tract infection group had higher proportions of Gram negative and fungus than the non-lower respiratory tract infection group; specifically E. coli (p 0.003), and Aspergillus (P < 0.001). CONCLUSIONS: There were two independent predictors of mortality in acute leukemia patients with FN: septic shock and lower respiratory tract infection regardless of leukemia type or pathogen. E. coli and Aspergillus were more common in those with lower respiratory tract infection than those without. No specific pathogens were found in cases of septic shock.

Importance of computed tomography pulmonary angiography for predict 30-day mortality in acute pulmonary embolism patients.

OBJECTIVE: The purpose of the present study was to assess the implications of different parameters of computed tomography pulmonary angiography (CTPA) to predict 30-day mortality in acute pulmonary embolism (APE) patients. MATERIAL AND METHOD: Patients who had clinical suspicion of APE and underwent CTPA were recruited in a retrospective cohort study. The findings of the CTPA included the parameters of right ventricular dysfunction (RVD), the severity of obstruction to the pulmonary artery by CT obstruction index, and the ratio of pulmonary trunk diameter and aorta. The endpoint of the study was established as the 30-day mortality associated with APE. RESULTS: A total of 238 patients with a confirmed APE diagnosis with CTPA were included in the study; 26 (10.9 %) of those patients died within 30 days. In patients with cancer and the Pulmonary Embolism Severity Index (PESI) class 5, the mortality rate was significantly higher. Compared with survivors, the mean CT obstruction index in the non-survivor group was significantly higher (p < 0.001). Higher mortality was associated with all RVD parameters identified by CTPA, such as the RV/LV ratio (p < 0.001), interventricular septum deviation grade 3 (p < 0.001), increased RV diameter (p < 0.001), and IVC contrast reflux (p < 0.001). The highest adjusted odds ratio was RV diameter at 1.094, followed by PESI and the CT obstruction index at 1.040. CONCLUSION: CTPA-detected RVD parameters and CT obstruction index can predict a 30-day mortality rate in APE patients and be used for risk stratification. In APE patients, the RV diameter of 53 mm or greater and the CT obstruction index >70% is associated with increased 30-day mortality.

Clinical factors associated with bloodstream infection at the emergency department.

BACKGROUND: Bloodstream infection (BSI) is a common urgent condition at the emergency department (ED). However, current guidelines for diagnosis do not specify the juncture at which blood cultures should be taken. The decision whether or not to obtain hemoculture is based solely upon clinical judgment and potential outcomes of inappropriately ordered cultures. This study aimed to find clinical factors present on ED arrival that are predictive of bloodstream infection. METHODS: This study was conducted retrospectively at the ED of a single tertiary care hospital in Thailand. We included adult patients with suspected infection based on blood culture who were treated with intravenous antibiotics during their ED visit. Independent positive predictors for positive blood culture were calculated by logistic regression analysis. RESULTS: A total of 169,578 patients visited the ED during the study period, 12,556 (7.40%) of whom were suspected of infection. Of those, 8177 met the study criteria and were categorized according to blood culture results (741 positive; 9.06%). Six clinical factors, including age over 55 years, moderate to severe CKD, solid organ tumor, liver disease, history of chills, and body temperature of over 38.3 °C, were associated with positive blood culture. CONCLUSIONS: Clinical factors at ED arrival can be used as predictors of bloodstream infection.

Vernonia cinerea pastilles is effective for smoking cessation.

BACKGROUND AND AIM: Vernonia cinerea (VC) is a herb that can alleviate nicotine addiction, potentially aiding in smoking cessation. Previous studies have examined four-to eight-week treatments using VC, but have found it to be ineffective. This study aimed to evaluate the smoking cessation effects of VC in addicted smokers over a longer treatment duration with pastilles. EXPERIMENTAL PROCEDURE: This was a randomized double-blinded controlled trial conducted at a community pharmacy. The inclusion criteria were age between 18 and 60 years, intention to quit smoking, and low to moderate level of nicotine addiction. All eligible participants were stratified according to nicotine addiction level and then randomly assigned either VC treatment or placebo. The VC group received two pastilles three times daily, while the control group received a placebo for 12 weeks. The outcomes were continuous abstinence rate (CAR) and point abstinence rate (PAR) at four and 12 weeks. RESULTS: There were 121 eligible participants; 10 participants were not willing to participate. In total, there were 111 eligible participants, 54 of whom were treated with VC (48.65%) and 57 of whom were given a placebo (51.35%). Baseline characteristics were comparable between the two groups. The VC group had a significantly higher chance of smoking cessation at 2.01 (95% CI of 1.03, 3.92) compared with the placebo group at the end of the study. There were no significant side effects in either group. CONCLUSION: The VC pastille group had significantly higher CAR than the placebo group at week 12.

Which diagnostic criteria of metabolic syndrome are predictors of cardiovascular diseases in elderly populations?

INTRODUCTION: Metabolic syndrome (MetS) is one contributing factor to cardiovascular diseases (CVD). Although there have been several reports showing MetS to be a risk factor for CVD, there are limited data available on which of the diagnostic criteria for MetS carries the greatest risk for CVD in the elderly population. This study thus aimed to evaluate these criteria in terms of risk of CVD in this population. METHODS: This was a retrospective cohort study conducted at three referral hospitals in Thailand. The study period was between January 1, 2007 and December 31, 2016. Eligible patients were identified whether presence of MetS or not at the beginning of study and followed until the end of study. The primary outcome of study was presence of CVD. Predictors for CVD were analyzed by Cox proportional-hazards regression. RESULTS: During the study period, there were 1080 patients who met the study criteria, 253 (23.42%) of whom had CVD. There were five factors significantly associated with CVD occurrence including age, smoking, SBP, FPG, and HDL-c. The two factors with the highest adjusted hazard ratio were FPG and SBP at 2.92 and 2.34, respectively. CONCLUSIONS: The three MetS criteria including SBP, FPG, and HDL-c may be predictors for cardiovascular diseases in elderly populations. Physician may need to focus on these particular factors of MetS in terms of CVD prevention in elderly patients.
