Sepsis, an infectious disease, is a life-threatening condition that arises when the response to infection causes injury to tissues and organs. The purpose of this study was to demonstrate whether ABHC-1 and ABHC-2, two functional extracts from herbal complex, have an anti-bacterial effect against Escherchia coli in vivo, in vitro experimental model. ABHC-1 and ABHC-2 showed the antibacterial activity against the bacteria by paper disc method. The minimum inhibitory concentration (MIC) was measured using alamar blue reagent. The MIC was shown at $60{\mu}g/ml$ from ABHC-1 and $500{\mu}g/ml$ from ABHC-2 against E. coli. We next examined the effect of ABHCs on the production of inflammatory cytokine, such as tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), which is related to the induction of inflammation, in RAW 264.7 cell. ABHC-1 and ABHC-2 increased $TNF-{\alpha}$ production of RAW 264.7 cell in a dose-dependent manner while two extract decreased $TNF-{\alpha}$ production in lipopolysaccharide (LPS)-stimulated RAW 264.7 cell in a dose-dependent manner. At a dose of $1{\times}10^8$ E. coli. i.p., non-treated mice were succumbed, while most of mice treated with ABHC-1 were survived. Therefore, our results suggest that ABHC-1 has anti-bacterial activity and can be a novel therapeutic agent against infectious diseases.

Background: Pulmonary thromboembolism (PTE) is a life-threatening disease with high mortality. This study aimed to assess the outcomes of surgical embolectomy and to clarify the sustained long-term effects of surgery by comparing preoperative, postoperative, and long-term follow-up echocardiography outcomes. Of 22 survivors, 21 were followed up for a mean (median) period of $6.8{\pm}5.4years$ (4.2 years). Methods: We retrospectively reviewed 27 surgical embolectomy cases for massive or submassive acute PTE from 2003 to 2016. Immediate and long-term follow-up outcomes of surgical embolectomy were assessed on the basis of 30-day mortality, long-term mortality, postoperative complications, right ventricular systolic pressure, and tricuspid regurgitation grade. Results: The 30-day and long-term mortality rates were 14.8% (4 of 27) and 4.3% (1 of 23), respectively. Three patients had major postoperative complications, including hypoxic brain damage, acute kidney injury, and endobronchial b leeding, respectively (3.7% each). Right ventricular systolic pressure (median [range], mm Hg) decreased from 62.0 (45.5-78.5) to 31.0 (25.7-37.0, p<0.001). The tricuspid valve regurgitation grade (median [range]) decreased from 1.5 (0.63-2.00) to 0.50 (0.50-1.00, p<0.05). The improvement lasted until the last echocardiographic follow-up. Conclusion: Surgical embolectomy revealed favorable mortality and morbidity rates in patients with acute massive or submassive PTE, with sustained long-term improvements in cardiac function.

The world is going through the most unprecedented time with the outbreak of novel Coronavirus disease (COVID-19), which has become a threat to millions. A Coronavirus is a group of viruses that cause a variety of diseases in mammals and birds leading to a range of illnesses in humans including common cold and more severe forms like severe acute respiratory syndrome Coronavirus (SARS-CoV), Middle East respiratory syndrome Coronavirus (MERS-CoV) and COVID-19, which are life-threatening. The virus gets its name from its shape which takes the form of a crown with protrusions around it. In December 2019, a pneumonia outbreak was reported in the Wuhan City of China, which was later traced to a novel strain of Coronavirus and termed as Novel COVID-19. It typically causes flu-like symptoms including fever, cough and shortness of breath and is transmitted through human-to-human and there is no cure for it till now. Thus, this bibliometric study has been carried out to analyze the research progress in Coronavirus and literature published during a period of 30 years (1989-2019). Data for the study were fetched from Web of Science(WoS) multidisciplinary database and the publication trends in terms of total articles, productive countries, institutions, journals, productive authors, most cited articles and authors, etc have been analyzed. In total, 4917 articles were retrieved; these were from 711 sources and were contributed by 14442 authors. The collaboration index was 3.11, which clearly indicates that there has been a lot of collaboration in this field. The most preferred journal for the study period was "Journal of Virology" and the maximum contribution has been from the University of Hong Kong.
Malaria is a life-threatening disease, and Africa is still one of the most affected endemic regions despite years of policy to limit infection and transmission rates. Further, studies into the variable efficacy of the vaccine are needed to provide a better understanding of protective immunity. Thus, the current study is designed to delineate the effect of each dose of vaccine on the transcriptional profiles of subjects to determine its efficacy and understand the molecular mechanisms underlying the protection this vaccine provides. Here, we used gene expression profiles of pre and post-vaccination patients after various doses of RTS,S based on samples collected from the Gene Expression Omnibus datasets. Subsequently, differential gene expression analysis using edgeR revealed the significantly (false discovery rate < 0.005) 158 downregulated and 61 upregulated genes between control vs. controlled human malaria infection samples. Further, enrichment analysis of significant genes delineated the involvement of CCL8, CXCL10, CXCL11, XCR1, CSF3, IFNB1, IFNE, IL12B, IL22, IL6, IL27, etc., genes which found to be upregulated after earlier doses but downregulated after the 3rd dose in cytokine-chemokine pathways. Notably, we identified 13 cytokine genes whose expression significantly varied during three doses. Eventually, these findings give insight into the dual role of cytokine responses in malaria pathogenesis. The variations in their expression patterns after various doses of vaccination are linked to the protection as it decreases the severe inflammatory effects in malaria patients. This study will be helpful in designing a better vaccine against malaria and understanding the functions of cytokine response as well.
Objectives: Fine particulate matter pollution has emerged as a significant life-threatening issue in Thailand. Recognizing the importance of environmental health literacy (EHL) in disease prevention is crucial for protecting public health. This study investigated EHL levels and aimed to identify associated factors among village health volunteers (VHVs) in the upper northern region of Thailand. Methods: A cross-sectional study was conducted to collect data from 710 VHVs using the EHL assessment tool developed by the Department of Health, Thailand. Results: The overall EHL score was moderate (mean, 3.28 out of a possible 5.0), with the highest and lowest domain-specific mean score for the ability to make decisions (3.52) and the ability to access (3.03). Multiple linear regression revealed that the factors associated with EHL score were area of residence (urban areas in Chiang Mai: B=0.254; urban areas in Lampang: B=0.274; and rural areas in Lampang: B=0.250 compared to rural areas in Chiang Mai), higher education levels (senior high school: B=0.212; diploma/high vocational certificate: B=0.350; bachelor's degree or above: B=0.528 compared to elementary school or lower), having annual health checkups compared to not having annual health check-ups (B=0.142), monthly family income (B=0.004), and individuals frequently facing air pollution issues around their residence (B=0.199) compared to those who reported no such issues. Conclusions: The VHVs exhibited moderate EHL associated with residence area, education, health check-ups, family income, and residential air pollution. Considering these factors is vital for enhancing VHVs' EHL through strategic interventions.
Even though there well developments in various treatment techniques for acute limb ischemia, this disease is both life threatening and limb threatening. We investigated early and mid-term results of operation for acute limb ischemia with symptoms, the combined diseases, location of occlusion, complication in our patients. Material and Method: A retrospective review was conducted in 54 patients (43 men, 11 women, mean age 67.2 years) presenting with acute limb ischemia due to arterial thrombosis or embolism between Jan. 1996 and Dec. 2003, initially underwent thromboembolectomy. Result: In 33 patients (61.1%) the timeinterval from the onset of symptom to admission was within 24 hours. Causes of acute limb ischemia were embolic occlusion (27.8%), native arterial thrombosis (66.7%), and bypass graft thrombosis (5.6%). The distribution of arterial occlusion location was at 8 aortoiliac (14.8%) and 43 distal to femoral (79.6%) and brachial (5.6%). Clinical categories were grade I in 64.8%, IIa in 24.1%, IIb in 7.4%, and III in 3.7%, All the patients were received embolectomy. Underlying diseases were heart disease (72.2%), hypertension (33.3%), cerebrovascular accident (16.7%) and diabetes (18.5%). History of smoking was noted in 96,3% of the cases. Mortality rate was 5.6% and overall amputation rate was 9.3% (5/54). The 1-year limb salvage rate was 93.62%. Postoperative complications were 1 wound infection, 1 G1 bleeding, 3 acute renal failure, and 1 compartment syndromes. The functional outcomes of the salvaged limb according to the recommended scale for gauging changes in clinical status, revised version in 1997 were +3 in 68.5%, +2 in 9.3%, +1 in 7.4%, -1 in 5.6%, -2 in 3.7%, and -3 in 5.6%. Conclusion: This study revealed 5.6% mortality and the amputation rate was 9.3%. We have retrospectively shown good results from early diagnosis & early operation. To improve outcome, early diagnosis and understand the underlying diseases, prompt treatment and operation would be appreciated.
While traditionally threatening human infectious diseases are decreasing, chronic diseases such as cancer and diabetes, including cardiovascular diseases, are spreading rapidly. Reflecting the characteristics of chronic diseases that are difficult to treat, the management of risk factors and the preparation of health promotion policies corresponding to them have emerged as important concerns around the world. Providing so-called multi-sector approach such as health promotion and disease prevention policy and solution for community response, The value of primary care is once again highlighted in the changed medical environment. As the existing medical delivery system has become difficult to cope with the people's desire for rapid aging, disease paradigm change, and quality of life improvement, European Union countries have made various efforts to improve the quality of their primary medical system, which provides continuous, com- prehensive and coordinated management. This paper examines the current status and problems of the healthcare delivery system in Korea, draws implications from the European Union examples related to the strengthening of primary care, and discusses the plans for establishing a patient-centered future medical delivery system.
Background: Spontaneous hemopneumothorax, occurring in 1% to 12% of patients with spontaneous pneumothorax, is a rare disorder that can potentially lead to life-threatening complications. Materials and methods: We have experienced 15 cases (2.28%) with spontaneous hemopneumothorax among 659 episodes of spontaneous pneumothorax for eight years, from 1990 to 1997, at our hospital. We studied our previously treated patients by retrospective case studies to determine the nature of optimal management. Results: There were 14 male and 1 female patients whose mean age was 27.5 years, ranging from 19 to 58. The sides with disorder were as following: right in 10 cases and left in 5, unilaterally. The amount of initial bleeding ranged from 400 to 1,500 mL and 8 patients received a homologous blood transfusion. Patients exhibited symptoms of chest pain, dyspnea, chest discomfort, and hypovolemic shock. We concluded that causes of this disease in our patients were a torn pleural adhesion (14 cases) and a rupture of vascularized bullae (1 case with an underlying intrinsic lung disease, tuberculosis). All patients underwent closed thoracostomy and had good results except for 3. One patient underwent thoracotomy within 3 days from the onset because of continuous active hemorrhage. Decortication was required in one case because of a reactive fluid collection in the pleural space, which led to impaired lung expansion. Another patient underwent thoracotomy due to a ipsilateral recurrent pneumothorax without blood collection. Conclusions: The goals of treatment include hemostasis and reexpansion of the collapsed lung. Thus, if patients arrive early at hospital, closed thoracostomy and transfusion are thought to be sufficient treatments, although early surgical repair has been considered recently.

A left atrial appendage aneurysm is a very rare medical condition which can develop by an inflammatory reaction or a degenerative change. If there is no accompanying anomaly, a left atrial appendage is considered a congenital disease. The majority of left atrial appendage aneurysms are detected incidentally because they usually do not cause any symptoms. Surgery is indicated, even for asymptomatic patients, because of the risk of life-threatening complications, such as atrial fibrillation, supraventricular tachycardia, systemic embolization, and cardiac arrest. Left atrial appendage aneurysms are usually treated by a median sternotomy with extracorporeal circulation, especially if the aneurysm has a broad base or contains a thrombus, but can treated by thoracotomy without extracorporeal circulation. We report a case of a successfully treated left atrial appendage aneurysm that was misdiagnosed as a partial pericardial defect without extracorporeal circulation in a 13-year old child.

Plastic bronchitis is a rare disease characterized by the recurrent formation of branching mucoid bronchial casts that are large and more cohesive than those that occur in ordinary mucus plugging. Casts may vary in size and can be spontaneously expectorated, but some require bronchoscopy for removal. Plastic bronchitis can therefore present as an acute life-threatening emergency if obstruction of the major airways occurs. Three of 22 reported patients with eosinophilic casts were fatal, with death due to central airway obstruction. Here, we report a child with no history of atopy, allergy, or congenital heart disease who was diagnosed with plastic bronchitis with eosinophilic casts. Although he was administered intravenous (iv) antibiotics; iv corticosteroids; and a vigorous pulmonary toilet regimen, including chest physiotherapy and routine bronchoscopic removal of casts, he had brain death secondary to hypoxic brain damage. Plastic bronchitis can be fatal when casts obstruct the major airways, as in the present case. Clinicians should intervene early if a patient exhibits signs and symptoms consistent with plastic bronchitis.
