Respiratory Tract Illness

Background Experimental studies have shown that vaccination can reduce viral replication to attenuate progression of influenza-associated lower respiratory tract illness (LRTI). However, clinical studies are conflicting, possibly due to use of non-specific outcomes reflecting a mix of large and small airway LRTI lacking specificity for acute lung or organ injury. Methods We developed a global ordinal scale to differentiate large and small airway LRTI in hospitalized adults with influenza using physiologic features and interventions (PFIs): vital signs, laboratory and radiographic findings, and clinical interventions. We reviewed the literature to identify common PFIs across 9 existing scales of pneumonia and sepsis severity. To characterize patients using this scale, we applied the scale to an antiviral clinical trial dataset where these PFIs were measured through routine clinical care in adults hospitalized with influenza-associated LRTI during the 2010–2013 seasons. Results We evaluated 12 clinical parameters among 1020 adults; 210 (21%) had laboratory-confirmed influenza, with a median severity score of 4.5 (interquartile range, 2–8). Among influenza cases, median age was 63 years, 20% were hospitalized in the prior 90 days, 50% had chronic obstructive pulmonary disease, and 22% had congestive heart failure. Primary influencers of higher score included pulmonary infiltrates on imaging (48.1%), heart rate ≥110 beats/minute (41.4%), oxygen saturation <93% (47.6%) and respiratory rate >24 breaths/minute (21.0%). Key PFIs distinguishing patients with severity < or ≥8 (upper quartile) included infiltrates (27.1% vs 90.0%), temperature ≥ 39.1°C or <36.0°C (7.1% vs 27.1%), respiratory rate >24 breaths/minute (7.9% vs 47.1%), heart rate ≥110 beats/minute (29.3% vs 65.7%), oxygen saturation <90% (14.3% vs 31.4%), white blood cell count >15,000 (5.0% vs 27.2%), and need for invasive or non-invasive mechanical ventilation (2.1% vs 15.7%). Conclusion We developed a scale in adults hospitalized with influenza-associated LRTI demonstrating a broad distribution of physiologic severity which may be useful for future studies evaluating the disease attenuating effects of influenza vaccination or other therapeutics.

A previously healthy 42-year-old male developed a fever and cough shortly after returning to Canada from overseas. Initially, he had mild upper respiratory tract infection symptoms and a cough. He was aware of the coronavirus disease-2019 (COVID-19) and the advisory to self-isolate and did so; however, he developed increasing respiratory distress over several days and called 911. On arrival at the emergency department (ED), his heart rate was 130 beats/min, respiratory rate 32 per/min, and oxygenation saturation 82% on room air. As per emergency medical services (EMS) protocol, they placed him on nasal prongs under a surgical mask at 5 L/min and his oxygen saturation improved to 86%.

HRSV (human respiratory syncytial virus) is a serious cause of lower respiratory tract illness in infants and young children. Designing inhibitors from the proteins involved in virus replication and infection process provides target for new therapeutic treatments. In the present study,in silicodocking was performed using motavizumab as a template to design motavizumab derived oligopeptides for developing novel anti-HRSV agents. Additional simulations were conducted to study the conformational propensities of the oligopeptides and confirmed the hypothesis that the designed oligopeptide is highly flexible and capable of assuming stable confirmation. Our study demonstrated the best specific interaction of GEKKLVEAPKS oligopeptide for glycoprotein strain A among various screened oligopeptides. Encouraged by the results, we expect that the proposed scheme will provide rational choices for antibody reengineering which is useful for systematically identifying the possible ways to improve efficacy of existing antibody drugs.

To identify risk factors associated with hospitalization for acute lower respiratory tract illness, 102 children &lt;2 years of age admitted to four Atlanta metropolitan area hospitals between December 1984 and June 1985 with the diagnosis of lower respiratory tract illness were studied. The most common causative agent associated with illness was respiratory syncytial virus, followed by other respiratory viruses, Haemophilus influenzae, and Streptococcus pneumoniae. The 102 case-patients were compared with 199 age- and sex-matched controls. A parent or guardian for each patient and control was interviewed by telephone regarding demographic data, care outside the home, breast-feeding, previous medical history, allergies, and smoking and illness in household members. Five factors were associated with lower respiratory tract illness in both a univariate analysis and a multiple logistic regression model (P &lt; .05). These factors were the number of people sleeping in the same room with the child, a lack of immunization the month before the patient was hospitalized, prematurity, a history of allergy, and regular attendance in a day-care center (more than six children in attendance). Care received outside of the home in a day-care home (less than or equal to six children in attendance) was not associated with lower respiratory tract illness. The suggestion made by our study and other studies was that for children &lt;2 years of age, care outside of the home is an important risk factor for acquiring lower respiratory tract illness, as well as other infectious diseases, and that this risk can be reduced by using a day-care home instead of a day-care center.

Abstract Background In the modern medicine, upper gastrointestinal endoscopy has become a definitive tool for diagnosis and management of many diseases. It is usually preformed in separate unit as day-case procedure and for outpatient clinic. The search of a safe and effective sedation for these patients is still an open topic. Objective The aim of the study is to compare the use of propofol and dexmedetomedine in upper GI endoscopy regarding the hemodynamics, sedative effect and the patient satisfaction. Methods Double – blinded, randomized controlled trial with allocation ratio 1:1 arranged in two parallel groups. This study was conducted in the endoscopy unit of Ainshams University Hospital, Cairo, Egypt within a period of 6 months started from April 2019. All recruited patients were adults undergoing upper gastrointestinal endoscopy. They were included in the study according to the following criteria: Age 21-60 years; elective procedures under general anesthesia with patients who completed eight hours of fasting; and physical Status: ASA I and II Patients after taking written and informed consent. Results Concerning the results of the study, there was no statistically significant difference considering the heart rate in relation to base line readings. The changes of heart rate between the two groups were significantly different with dexmedetomidine associated with lower readings. Respiratory rate and oxygen saturation were insignificantly different in both groups. Time of induction was significantly shorter in propofol than dexmedetomidine (P &lt; 0.001) and time to reach full recovery identified by modified Alderete’s score 10/10 was significantly shorter in dexmedetomidine than propofol (P &lt; 0.014). There was a significant difference between the two dugs concerning the patients and endoscopists satisfaction. The patients were more satisfied with propofol (P 0.047), while the endoscopists were more satisfied with dexmedetomidine (P 0.034). Conclusion Dexmedetomidine and propofol are equally effective and safe to provide enough sedation for upper gastrointestinal endoscopy in a day-case manner. Advantages of dexmedetomidine were providing analgesic effect, rapid recovery from sedation and stability of respiratory rate and oxygen saturation. However, there were some disadvantages such as the bradycardia and patient dissatisfaction although the bradycardia can be utilized in cardiac patients as a safety factor against myocardial ischemia. Other point noticed that using dexmedetomidine for sedation was more costly than propofol and requires the usage of a syringe pump for accurate dosing. On the contrary, propofol is cheap and available in all centers with rabid onset of induction but it causes hypotension and respiratory depression which might be risky in cardiac patients.

Abstract Background Preventing severe complications of influenza such as hospitalization is a public health priority; however, estimates of influenza vaccine effectiveness (VE) against influenza-associated acute lower respiratory tract infection (LRTI) hospitalizations are limited. We examined influenza VE against influenza-associated LRTIs in hospitalized adult patients. Methods We retrospectively analyzed data from a randomized trial of oseltamivir treatment in adults hospitalized with LRTI in Louisville, Kentucky, from 2010 to 2013. Patients were systematically tested for influenza at the time of enrollment. We estimated VE as 1 – the adjusted odds ratio (aOR) of antecedent vaccination in influenza-positives vs negatives × 100%. Vaccination status was obtained by patient self-report. Using logistic regression adjusting for age, sex, season, timing of illness, history of chronic lung disease, and activities of daily living, we estimated VE against hospitalized influenza-associated LRTIs and community-acquired pneumonia (CAP) with radiographic findings of infiltrate. Results Of 810 patients with LRTI (median age, 62 years), 184 (23%) were influenza-positive and 57% had radiographically confirmed CAP. Among influenza-positives and -negatives, respectively, 61% and 69% were vaccinated. Overall, 29% were hospitalized in the prior 90 days and &gt;80% had comorbidities. Influenza-negatives were more likely to have a history of chronic obstructive pulmonary disease than influenza-positives (59% vs 48%; P = .01), but baseline medical conditions were otherwise similar. Overall, VE was 35% (95% CI, 4% to 56%) against influenza-associated LRTI and 51% (95% CI, 13% to 72%) against influenza-associated radiographically confirmed CAP. Conclusions Vaccination reduced the risk of hospitalization for influenza-associated LRTI and radiographically confirmed CAP. Clinicians should maintain high rates of influenza vaccination to prevent severe influenza-associated complications.
