Abstract
Background Influenza caused by H1N1 virus still affects human health. There is currently no effective strategy against H1N1 virus infection. The present study is to evaluate the mechanism of Shufeng Jiedu Capsule (SFJDC) in the treatment of H1N1 infection using an integrated systems pharmacology approach and experimental validation. SFJDC is recommended for the treatment of H1N1 infection in traditional Chinese medicine (TCM), whose mechanism of action is not precise. Methods: We systematically analyzed SFJDC using a systematic pharmacology and ADME screening model, and predicted effective targets using systematic drug targeting (SysDT) algorithm. Subsequently, the network of interactions between compounds and targets was built to help in the discovery of new drugs. In addition, the pathway of molecular action was determined by using enrichment analysis from the predicted targets. what is more, molecular docking also applied to predict the specific binding sites and binding capacity of active compounds and related targets, which validated the results of the compounds-targets network (C-T network). Finally, the mechanism of SFJDC effected on autophagy and virus replication in H1N1 virus-infected RAW264.7 mouse macrophage cells were experimentally verified. Results: The systematic pharmacology results suggested that 68 candidate compounds were obtained from SFJDC, which interacted with 74 different targets related to inflammation and the immune system. The CCK-8 results showed that different concentrations of SFJDC serum had no significant inhibitory effect on the viability of RAW264.7 cells. LC3-II was significantly increased after virus infection compared to the control group, while it was inhibited by different concentrations of SFJDC serum. H1N1 virus nucleocapsid protein (NP protein) was significantly reduced in the high concentration group, Interleukin-1β (IL-1β), Interleukin-6 (IL-6), Tumor Necrosis Factor-α (TNF-α), and viral M1 gene were significantly reduced compared to the H1N1 group. Conclusions: The integrated systemic pharmacological approach and experimental validation not only provide a precise explanation of the molecular mechanism of SFJDC in the treatment of H1N1 infection but also provide valuable clues for the development of novel drug strategies to control the H1N1 infection.

Abstract
We present an uncommon case of H1N1 triggered thyroid storm in a patient with previously undiagnosed Grave's Disease. This case illustrates the challenges of diagnosing thyroid storm in the emergency department and the importance of including it in the differential when treating more common diagnoses that fail to respond to usual therapies. Thyroid storm is an endocrinologic emergency and requires prompt recognition and treatment. However, it remains a diagnostic challenge as there is no laboratory test specific to thyroid storm. Diagnosis relies on clinical suspicion in corroboration with patient presentation, laboratory findings and response to therapy.

Abstract
The present study aimed to explore the potential roles and mechanism of microRNA-4485 (miR-4485) in severe influenza pneumonia. miR-4485 expression was detected in patients with severe H1N1 pneumonia using quantitative PCR. Furthermore, the effects of aberrantly expressed miR-4485 on H1N1-infected A549 cells were investigated using Cell Counting Kit-8, terminal deoxynucleotidyl transferase dUTP nick end labeling, western blotting and (ELISA) assays. Furthermore, the regulatory relationships between miR-4485 and the STAT3-mediated PI3K/AKT/mTOR signaling pathway were explored using a luciferase reporter and rescue assay. MiR-4485 expression was downregulated following H1N1 infection and in patients with H1N1 pneumonia. In addition, miR-4485 alleviated H1N1-induced A549 cell injury by promoting cell viability and the production of cytokines, as well as reducing apoptosis in A549 cells. Furthermore, STAT3 was revealed to be a target gene of miR-4485. Additionally, STAT3 silencing reversed the protective effects of miR-4485 knockdown on H1N1-induced cell injury via inhibition of the PI3K/AKT/mTOR signaling pathway. In conclusion, miR-4485 inhibited H1N1-induced severe pneumonia in A549 cells by targeting STAT3 via the PI3K/AKT/mTOR signaling pathway.

Abstract
CONTEXT India experienced pandemic phase of H1N1 in May 2009 to December 2010. The postpandemic phase went on from January 2011 to December 2014. As per the WHO, all countries should immunize their health-care workers as a first priority to protect the essential health infrastructure. AIMS The aim of the study is to assess the level of awareness and acceptance of influenza vaccine among physicians and also the perception of physicians regarding H1N1 infection. This study also examined time of vaccine administration in relation with efficacy concerns based on literature. SETTINGS AND DESIGN A vaccination campaign was conducted for all health-care workers of Seth GSMC and KEM Hospital, Mumbai, in the month of July 2017 based on which a cross-sectional observational study was conducted among the physicians of the same institute. METHODS After ethical clearance, a prevalidated pretested survey based on a pilot survey of 20 physicians was distributed among physicians, which was based on the awareness and acceptance of H1N1 vaccination among physicians and perception of H1N1 infection. Effective sample size was 272. STATISTICAL ANALYSIS USED Descriptive statistics and Chi-square test were generated for the survey responses. All the continuous variables were reported as mean, median, and range. Categorical variables were reported as tables and pie charts. P < 0.05 was taken as significant. Data analysis was done with SPSS version 21. RESULTS The overall vaccine compliance was 29.8%. This study has found that area of work, deficiency in knowledge about adverse effect of vaccine, misconceptions regarding vaccine, and concerns about efficacy and duration of vaccine are the important factors which lead to decreased vaccine compliance. Furthermore, it is found during the study that timing of vaccination was not given due importance as considering the epidemiological pattern. CONCLUSIONS More emphasis should be given to education sessions and counseling of physicians regarding H1N1 vaccination and oseltamivir therapy. At administrative level, more focus should be given on timing of vaccination and other logistics. Vaccine campaigns should be conducted ideally 1 month before expected rise in cases. Quadrivalent vaccine would be more appropriate over trivalent based on epidemiology of infection in India.

Abstract
A 19-year-old male was admitted to our clinic with a diagnosis of suspected acute pericarditis and acute coronary syndrome. The initial diagnostics at our clinic revealed fulminant myocarditis. Twenty-four hours after admission, the patient's condition deteriorated, and he required mechanical ventilation and cardiopulmonary resuscitation. Unfortunately, the patient died. Clinical course, postmortem pathohistological findings and virus serology indicated that an H1N1 viral caused fulminant myocarditis and was the primary manifestation.

Abstract
BACKGROUND H1N1 influenza A virus infections were first reported in April 2009 and spread rapidly, resulting in mortality worldwide. The aim of this study was to evaluate patients with H1N1 infection treated in the intensive care unit (ICU) in Bursa, Turkey. METHODS Demographic characteristics, clinical features, and outcome relating to H1N1 infection were retrospectively analysed in patients treated in the ICU. RESULTS Twenty-three cases of H1N1 infection were treated in the ICU. The mean age of patients was 37 years range: (17-82). Fifteen patients were female (65.2%). The mean Acute Physiology and Chronic Health Evaluation (APACHE) II score was 19 range: (5-39). The most common symptoms were dyspnea (73.9%), fever (69.6%), and cough (60.9%). Mechanical ventilation was required for all patients. Oseltamivir and antibiotics were administered to all patients. Six (26.1%) patients died. APACHE II scores were higher in the deceased 28.5 range: [16-39] vs. 14 range: [5-28] in survivors; p = 0.013). CONCLUSION When compared to the literature, the demographic, epidemiological, and clinical characteristics were similar in the cases we encountered. The mortality rate was high despite the use of appropriate treatment. We believe that the high mortality is related to higher APACHE II scores. The H1N1 virus should be considered in community acquired pneumonia, especially in younger patients presenting with severe pneumonia.

Abstract
Acute severe bronchospasm is an emergency situation and sometimes these children may fail to respond to conventional treatment and deteriorate rapidly to respiratory failure requiring mechanical ventilation. We present a case of 2-year-old girl, who presented with severe bronchospasm resulting in respiratory failure not responding to conventional management including mechanical ventilation and was found to be H1N1 positive. She was treated with ketamine infusion, which led to prompt improvement in airway obstruction.

Abstract
BACKGROUND H1N1 pandemic in 2009-2010 created a state of panic not only in India, but in the whole world. The clinical picture seen with H1N1 is different from the seasonal influenza involving healthy young adults. Critical care management of such patients imposes a challenge for anesthesiologist. MATERIALS AND METHODS A retrospective analysis of hospitalized positive H1N1 patients was performed from July 2009-June 2010. Those requiring the ventilatory support were included in the study. RESULT 54 patients were admitted in the swine-flu ward during the study period out of which 19 required ventilatory support. The average day of presentation to the health care facility was 6(th) day causing delay in initiation of antiviral therapy and increased severity of the disease. 65% of the ventilated patients were having associated comorbidities. Mortality was 74% among ventilated patients. CONCLUSION Positive H1N1 with severe disease profile have a poor outcome. Early identification of high-risk factors and thus early intervention in the form of antiretroviral therapy and respiratory care will help in reducing the overall mortality.

Abstract
A 17-year-old H1N1-positive patient was successfully extubated after 25 days of ventilatory support for treatment of viral pneumonia which was complicated by empyema thoracis due to Candida albicans. Hematogenous spread was suspected as simultaneous culture of ascitic fluid identified Candida species sensitive to flucytosine but resistant to amphotericin B and azole group of antifungals. Monotherapy with flucytosine led to clinical and radiological improvement.

Abstract
The pandemic novel influenza A (H1N1) infection was considered widespread in Brazil on July 16, 2009. Since then, 46,810 cases of acute respiratory syndrome have been reported in Brazil, most of them concentrated in São Paulo. Through September 16, we have confirmed 9,249 cases of novel influenza A H1N1in Brazil, including 699 deaths. The mortality rate observed in Brazil is 0.47/100,000 inhabitants and varies according to region. In this period, São Paulo registered 3733 cases (40.3% of the total) of novel influenza A (H1N1) infection and 327 deaths, reflecting a mortality rate of 0.79/100,000 inhabitants. The Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC) is a reference center for H1N1 cases in São Paulo. During the winter of 2009, 472 patients in this hospital were diagnosed with H1N1 infection; of these, 210 were admitted, and 16 died. To control this pandemic and to provide adequate care for these patients, the Hospital das Clínicas implemented "bundles" including prevention strategies, an epidemiologic surveillance service, availability of fast diagnosis, antiviral treatment and training of staff. The purpose of this manuscript is to describe the epidemiologic features of novel human influenza A (H1N1) infection in the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo during the winter period of the 2009 pandemic.
