Influenza outbreaks are associated with significant morbidity. Our aim was to determine the factors associated with increased mortality in hospitalized patients admitted with diagnosis of influenza, at a tertiary care center in Pakistan. This study included all adult patients with an influenza infection, confirmed by realtime reverse-transcriptase polymerase-chain-reaction (RT-PCR) at Aga Khan University Hospital Pakistan. In our study, 112 patients with laboratory-confirmed influenza virus infection were admittedat our hospital from the 1st of January 2013 to the 31st of December 2018. Eighty-nine patients (79.46%) were managed in ward or special care units and 23 patients (20.5%) received treatment in intensive care unit (ICU). The overall mortality in our study was 15/112 (13.4%) with the mortality rate of ICU patients being 47.8% while the mortality rate of patients treated in special care units and wards was only 4.5%. The mean age of patients with influenza infection was 58.1 years (±16.6). Influenza virus type A was found in 87 patients (77.6%), while influenza type B was present in only 25 (22.4%) patients. Out of the 15 non-survivors, 14 had influenza A. Only 17 patients (15.2%) were found to have positive culture of respiratory specimen, out of which 3 were non-survivors and 14 were survivors. Our analysis identified septic shock (odds ratio 45.24; 95%, confidence interval 6.20-330; p<0.001), renal failure (odds ratio 10.88; 95%, confidence interval 1.61-73.52; p=0.01) and ICU stay (odds ratio 17.22; 95%, confidence interval 2.68-110.5; p=0.003) as independent risk factors associated with in-hospital mortality.

Central venous catheter-related bloodstream infection is clinically important because of its high mortality rate. This prospective study shows by multivariate analysis that the use of maximal sterile barrier precautions (odds ratio, 5.205 [95% confidence interval, 0.015-1.136]; P= .023) and the use of antimicrobial-coated catheters (odds ratio, 5.269 [95% confidence interval, 0.073-0.814]; P = .022) are independent factors associated with a lowered risk of acquiring a central venous catheter-related bloodstream infection.

Background.During influenza outbreaks, fever and cough are the most accurate symptoms in predicting influenza virus infection in the community.Objective.To determine the usefulness of fever, cough, and other symptoms for diagnosing influenza virus infection in hospitalized patients.Design.Prospective cohort study.Setting.Three wards (pulmonology, internal medicine and infectious diseases, and geriatrics) of a tertiary care hospital in the Netherlands.Patients.All patients staying in the wards during peak national influenza activity in the 2005-2006 and 2006-2007 influenza seasons.Methods.During peak influenza activity, the presence of fever, cough, and/or other symptoms possibly associated with influenza was monitored for all patients, and nose and throat swab samples were taken twice weekly for virologic analysis.Results.Of 264 patients, 23 (9%) tested positive for influenza virus. The positive predictive value of fever and cough for the diagnosis of influenza virus infection was 23% (95% confidence interval, 0%-62%), and the sensitivity was 35% (95% confidence interval, 11%-58%). The combination of symptoms with the highest positive predictive value (40%) was that of cough, chills, and obstructed nose or coryza. The combination of cough and chills or fever had the highest sensitivity (60%). None of the combinations of symptoms had both a positive predictive value and a sensitivity higher than 40%.Conclusions.Both the sensitivity and the positive predictive value of fever, cough, and/or other symptoms for the diagnosis of influenza virus infection in hospitalized patients are low. The use of these common symptoms for treatment decisions and infection control management will probably be insufficient to contain a nosocomial outbreak, because many influenza cases will remain unidentified.

Background: Over the last 100 years, the development and mass production of chemically synthesized drugs have revolutionized health care in most parts of the world. However, large sections of the population in developing countries still depend on traditional medicines for their primary health care needs. More than 88% of Ethiopian parents use different forms of traditional medicine for their children. Therefore, this study aimed to determine factors associated with parental traditional medicine use for children in Fagita Lekoma Woreda. Method: Community-based cross-sectional study was conducted from 1 to 30 March 2019 in Fagita Lekoma Woreda. Data collection tool was a structured interviewer-administered questionnaire. Both descriptive and inferential statistics were used to present the data. Odds ratio and binary and multiple logistic regression analysis were used to measure the relationship between dependent and independent variables. Results: Among 858 participants, 71% of parents had used traditional medicine for their children within the last 12 months. Parents who cannot read and write (adjusted odds ratio = 6.42, 95% confidence interval = 2.1–19.7), parents with low monthly income (adjusted odds ratio = 4.38, 95% confidence interval = 1.58–12.1), and those who had accesses to traditional medicine (adjusted odds ratio = 2.21, 95% confidence interval = 1.23–3.98) were more likely to use traditional medicine for their children. Urban residents (adjusted odds ratio = 0.20, 95% confidence interval = 0.11–0.38) and members of community-based health insurance (adjusted odds ratio = 0.421, 95% confidence interval = 0.211–0.84) were less likely to use traditional medicine for their children. Conclusions: Our study revealed that the prevalence of traditional medicine remains high. Educational status, monthly income, residence, accessibility to traditional medicine, and being a member of community-based health insurance were predictors of potential traditional medicine use. Therefore, the integration of traditional medicine with modern medicine should be strengthened. Community education and further study on efficacy and safety of traditional medicines should be also given great attention.

Background: Despite thrombocytopenia, patients with sepsis often experience hypercoagulability. However, limited information is available on the prevalence and effect of hypercoagulability in patients with sepsis-induced thrombocytopenia. Hence, we evaluated the prevalence of hypercoagulability and the association between hypercoagulability and clinical outcomes in septic shock patients with thrombocytopenia. Methods: Thromboelastography (TEG) was performed prospectively in 1294 patients with septic shock at the emergency department (ED) between January 2016 and December 2019. After excluding 405 patients who did not require resuscitation, refused enrollment, or developed septic shock after ED presentation, 889 patients were included. We defined thrombocytopenia as an admission platelet count lower than 150,000/µl according to SOFA score. We defined hypocoagulability and hypercoagulability as coagulation index (CI)< −3 and >3 on TEG, respectively. Results: Of the 889 septic shock patients (mean age 65.6 ± 12.7 years, 58.6% male), 473 (53.2%) had thrombocytopenia. Eighty-five (18.0%) patients showed hypercoagulable TEG and73 (15.4%) patients showed hypocoagulable TEG. The hypercoagulable TEG group had a significantly higher fibrinogen level and a lower 28-day mortality rate than the normal and hypocoagulable TEG groups (518 vs. 347 and 315 mg/dL; 7.1% vs. 21.1% and 36.8%, P < 0.01, respectively). In multivariate analysis, hypercoagulable TEG was associated with a decreased mortality rate (odds ratio: 0.395; 95% confidence interval, 0.162-0.965). Conclusions: In septic shock patients with thrombocytopenia, hypercoagulability was not uncommon. TEG can quickly distinguish the hypercoagulability and hypocoagulability states and serve as a valuable tool for evaluating the degree and risk in septic shock patients with thrombocytopenia.

ABSTRACT BACKGROUND: Hip fractures are one of the leading causes of disability and dependency among the elderly. The rate of hip fractures has been progressively increasing due to the continuing increase in average life expectancy. Surgical intervention is the mainstay of treatment, but with an increasing prevalence of comorbid conditions and decreased functional capacity in elderly patients, more patients are prone to postoperative complications. OBJECTIVES: Assess the value of surgical intervention for hip fractures among the elderly by quantifying the 1-year mortality rate and assessing factors associated with mortality. DESIGN: Medical record review. SETTING: Tertiary care center. PATIENTS AND METHODS: All patients 60 years of age or older who sustained a hip fracture between the period of 2008 to 2018 in a single tertiary healthcare center. Data was obtained from case files, using both electronic and paper files. MAIN OUTCOME MEASURES: The 1-year mortality rate for hip fracture, postoperative complications and factors associated with mortality. SAMPLE SIZE: 802 patients. RESULTS: The majority of patients underwent surgical intervention (93%). Intra- and postoperative complications were 3% and 16%, respectively. Four percent of the sample died within 30 days, and 11% died within one year. In a multivariate analysis, an increased risk of 1-year mortality was associated with neck of femur fractures and postoperative complications ( P =.034, <.001, respectively) CONCLUSION: The 1-year mortality risk in our study reinforces the importance of aggressive surgical intervention for hip fractures. LIMITATION: Single-centered study. CONFLICT OF INTEREST: None.

Abstract Purpose Routine blood parameters, such as the lymphocyte (LYM) count, platelet (PLT) count, lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), LYM*PLT and mean platelet volume-to-platelet ratio (MPV/PLT), are widely used to predict the prognosis of infectious diseases. We aimed to explore the value of these parameters in the early identification of influenza virus infection in children.Methods We conducted a single-center, retrospective, observational study of fever with influenza-like symptoms in pediatric outpatients from different age groups and evaluated the predictive value of various routine blood parameters measured within 48 hours of the onset of fever for influenza virus infection.Results The LYM count, PLT count, LMR and LYM*PLT were lower, and the NLR and MPV/PLT were higher in children with an influenza infection (PCR-confirmed and symptomatic). The LYM count, LMR and LYM*PLT in the influenza infection group were lower in the 1- to 6-year-old subgroup, and the LMR and LYM*PLT in the influenza infection group were lower in the >6-year-old subgroup. In the 1- to 6-year-old subgroup, the cutoff value of the LMR for predicting influenza A virus infection was 3.75, the sensitivity was 81.87%, the specificity was 84.31%, and the area under the curve (AUC) was 0.886; the cutoff value of the LMR for predicting influenza B virus infection was 3.71, the sensitivity was 73.58%, the specificity was 84.31%, and the AUC was 0.843. In the >6-year-old subgroup, the cutoff value of the LMR for predicting influenza A virus infection was 3.05, the sensitivity was 89.27%, the specificity was 89.61%, and the AUC was 0.949; the cutoff value of the LMR for predicting influenza B virus infection was 2.88, the sensitivity was 83.19%, the specificity was 92.21%, and the AUC was 0.924.Conclusions Routine blood tests are simple, inexpensive and easy to perform, and they are useful for the early identification of influenza virus infection in children. The LMR had the strongest predictive value for influenza virus infection in children older than 1 year, particularly influenza A virus infection.

Abstract Background Sepsis is associated with excessive release of catecholamines, which causes tachycardia and is correlated with poor clinical outcome. β-Blockers (BBs) may blunt this effect on heart rate (HR). The objective of this study is to assess whether long-term BB therapy is associated with better clinical outcomes in patients with sepsis admitted to internal medicine wards. Methods We performed a single-center, observational cohort study. We included adult patients who were hospitalized in medicine departments due to sepsis. A propensity score model for BB therapy was used to match patients. The primary outcome was the 30-day all-cause mortality rate. A multivariate analysis was performed to identify risk factors for an adverse outcome. Patients were stratified according to absolute tachycardia (HR ≥100/min) or relative tachycardia at presentation (tachycardia index above the third quartile, with tachycardia index defined as the ratio of HR to temperature). Results A total of 1186 patients fulfilled the inclusion criteria. In the propensity-matched cohort patients given BB treatment were younger (median age [interquartile range], 74 [62–82] vs 81 [68–87] years; P ≤ .001). BB treatment was associated with reduction in 30-day mortality rates for patients with absolute tachycardia (odds ratio, 0.406; 95% confidence interval, .177–.932). Final model with interaction variable of BB treatment with HR was associated with short-term survival (odds ratio, 0.38; 95% confidence interval, .148–.976). Selective BB therapy had a stronger protective effect than nonselective BB therapy. Conclusions Long-term BB therapy was associated with decreased mortality rate in patients hospitalized with sepsis in internal medicine wards exhibiting absolute and relative tachycardia.

Study design: Retrosepctive analysis of prospectively collected data from the multicentre Canadian Surgical Spine Registry (CSORN). Objective: Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord dysfunction in North America. Few studies have evaluated return to work (RTW) rates after DCM surgery. Our goals were to determine rates and factors associated with postoperative RTW in surgically managed patients with DCM. Methods: Data was derived from the prospective, multicenter Canadian Spine Outcomes and Research Network (CSORN). From this cohort, we included all nonretired patients with at least 1-year follow-up. The RTW rate was defined as the proportion of patients with active employment at 1 year from the time of surgery. Unadjusted and adjusted analyses were used to identify patient characteristics, disease, and treatment variables associated with RTW. Results: Of 213 surgically treated DCM patients, 126 met eligibility, with 49% working and 51% not working in the immediate period before surgery; 102 had 12-month follow-up data. In both the unadjusted and the adjusted analyses working preoperatively and an anterior approach were associated with a higher postoperative RTW ( P < .05), there were no significant differences between the postoperative employment groups with respect to age, gender, preoperative mJOA (modified Japanese Orthopaedic Association) score, and duration of symptoms ( P > .05). Active preoperative employment (odds ratio = 15.4, 95% confidence interval = 4.5, 52.4) and anterior surgical procedures (odds ratio = 4.7, 95% confidence interval = 1.2, 19.6) were associated with greater odds of RTW at 1 year. Conclusions: The majority of nonretired patients undergoing surgery for DCM had returned to work 12 months after surgery; active preoperative employment and anterior surgical approach were associated with RTW in this analysis.

RIG-I plays an essential role in the duck innate immune response to influenza infection. RIG-I engages the critical adaptor protein mitochondrial antiviral signaling (MAVS) to activate the downstream signaling pathway. The influenza A virus non-structural protein PB1-F2 interacts with MAVS in human cells to inhibit interferon production. As duck and human MAVS share only 28% amino acid similarity, it is not known whether the influenza virus can similarly inhibit MAVS signaling in avian cells. Using confocal microscopy we show that MAVS and the constitutively active N-terminal end of duck RIG-I (2CARD) co-localize in DF-1 cells, and duck MAVS is pulled down with GST-2CARD. We establish that either GST-2CARD, or duck MAVS can initiate innate signaling in chicken cells and their co-transfection augments interferon-beta promoter activity. Demonstrating the limits of cross-species interactions, duck RIG-I 2CARD initiates MAVS signaling in chicken cells, but works poorly in human cells. The D122A mutation of human 2CARD abrogates signaling by affecting MAVS engagement, and the reciprocal A120D mutation in duck 2CARD improves signaling in human cells. We show mitochondrial localization of PB1-F2 from influenza A virus strain A/Puerto Rico/8/1934 (H1N1; PR8), and its co-localization and co-immunoprecipitation with duck MAVS. PB1-F2 inhibits interferon-beta promoter activity induced by overexpression of either duck RIG-I 2CARD, full-length duck RIG-I, or duck MAVS. Finally, we show that the effect of PB1-F2 on mitochondria abrogates TRIM25-mediated ubiquitination of RIG-I CARD in both human and avian cells, while an NS1 variant from the PR8 influenza virus strain does not.

Influenza viruses have been shown to use autophagy for their survival. However, the proteins and mechanisms involved in the autophagic process triggered by the influenza virus are unclear. Annexin-A1 (ANXA1) is an immunomodulatory protein involved in the regulation of the immune response and Influenza A virus (IAV) replication. In this study, using clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 (CRISPR associated protein 9) deletion of ANXA1, combined with the next-generation sequencing, we systematically analyzed the critical role of ANXA1 in IAV infection as well as the detailed processes governing IAV infection, such as macroautophagy. A number of differentially expressed genes were uniquely expressed in influenza A virus-infected A549 parental cells and A549 ∆ANXA1 cells, which were enriched in the immune system and infection-related pathways. Gene ontology and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway revealed the role of ANXA1 in autophagy. To validate this, the effect of mechanistic target of rapamycin (mTOR) inhibitors, starvation and influenza infection on autophagy was determined, and our results demonstrate that ANXA1 enhances autophagy induced by conventional autophagy inducers and influenza virus. These results will help us to understand the underlying mechanisms of IAV infection and provide a potential therapeutic target for restricting influenza viral replication and infection.
