Abstract:
Includes bibliographical references (leaves 69-77).
Triathletes, in particular Ironman triathletes, undergo intense training and compete in a very physically demanding race. Medical conditions in the pre-race period in these triathletes have not been well documented, but there is evidence form other endurance sports that symptoms of respiratory tract infection are particularly common. However, the prevalence, causes and consequences of these symptoms have not been studied in Ironman triathletes. The aims of this study were: 1) to determine the incidence of respiratory tract symptoms (RTS) in triathletes preparing for an Ironman Triathlon, 2) to establish the factors associated with the development of these RTS, and 3) to determine the effects of the RTS on pre-race training and race performance. Methods: In this cross-sectional descriptive study, 304 triathletes entering the 2006 Ironman triathlon in South Africa were recruited as subjects. All the subjects completed a validated questionnaire in the 1-3 days before the race (during registration). The questionnaire contained sections on demographics, training and previous competitions, common general medical conditions that they may have experienced, and a detailed section pertaining to RTS and allergies, including use of medication. Data on race performance was collected after completion of the race. Subjects were divided into the following groups, based on their self-reported history of RTS in the 6 weeks period prior to the race: no RTS, all RTS, only upper respiratory tract symptoms (URTS), lower respiratory tract and/or systemic symptoms (LRT +SS).

Abstract:
Two studies were undertaken to investigate the relationship between upper respiratory tract infection (URTI) and exercise performance. The first study documented the incidence of URTI in an athletic population and the second study determined the effect of URTI on exercise performance during the recovery period. Endurance runners (n=29) were used for these studies and the athletes were monitored for 45 months. During this time the subjects ran an average of 40 kilometers/week. In the first study, 22 reports of symptoms (n=22) of URTI occurred during the 45-month period. Of these, 10 subjects (n=10) were ill for less than 3 days. All 10 subjects reported their symptoms directly following an endurance event. The other 12 subjects (n=12) were ill for 5 days and longer and fulfilled the inclusion criteria for illness due to infection. The incidence of symptoms of URTI/1000 hours of training for the group of 29 runners was 1,26. The incidence of symptoms for the 10 athletes not fulfilling the inclusion criteria for illness was 0.58 and the incidence for the 12 athletes fulfilling the inclusion criteria was 0.69. The odds ratio for the athletes (n=22) for developing symptoms of URTI during a year is 1.03 compared to the odds ratio of 2.5 for the general population during the similar period. These results seem to indicate that 45% of athletes (n=10) who reported URTI symptoms directly following strenuous exercise do not have clinical infection. Furthermore, the study indicates that regular, moderate, endurance exercise may afford protection against URTI, when compared to the general population. In the second study, 5 athletes (n=5) of the original 12 subjects with URTI complied with all the test protocols. On recruitment, baseline tests were done for muscle strength, muscle endurance, aerobic endurance and maximal effort to exhaustion. Following the development of the URTI, the above parameters were tested over six days on days 0, 2, 4 and 6. After regaining their pre-illness fitness levels over a three-month period, the subjects were detrained for comparative periods and the above tests repeated on similar days for comparative purposes. iv Parameters for muscle strength and muscle endurance [Work (Joule), Power (Watt), Torque to mass (Nm/kg), and Total power (Watt)] appeared to be unaffected following periods of illness and following comparative periods of detraining.

Abstract:
Upper respiratory tract infections (URTI) are one of the most common illnesses affecting the general population and particularly athletes, often reducing the individual capacity of physical performance. Epidemiological data suggest that intensive exercise, training and competition may increase susceptibility to respiratory infections. On the other hand, some studies defend that less active subjects may reduce their risk of URTI by engaging in moderate exercise training. Nevertheless, reports are not unanimous and frequently contained various limitations. The higher incidence of infections in elite athletes has been widely attributed to immune suppression induced by exhaustive exercise, however this has not been clearly demonstrated. The present series of studies aimed to investigate the relationship between physical activity and the incidence of URTI in young healthy females with a range of physical activity levels, from sedentary to elite athletes (tennis players). Additionally, it was intended to explore the temporal association between specific characteristics of tennis training and competition, the incidence of URTI, and salivary lgA levels (μg.mr1 ; μg.min-1 ) and changes, in elite female tennis players over a 12-week period. To accomplish the objectives described, a practical method for quantifying tennis play was validated and applied. Major findings of this research include the greater incidence of URTI symptomatology in girls with low or extremely high levels of physical activity as compared to those with moderate levels. Moreover, the incidence of URTI in elite tennis players was directly correlated with the training load and competition level, on a weekly basis. In the subsequent study, one hour of intense tennis play produced a significant drop in salivary lgA secretion rate (S-lgA), and the magnitude of the immune suppression was directly associated with the amount of training undertaken during the previous day and week (P<0.05). Nevertheless, tennis training did not seem to suppress chronically salivary lgA as positive correlations were found between resting salivary lgA levels of concentration and secretion rate, and the amount of training undertaken previously. Finally, it was noted a sharper post-exercise drop in S-lgA in occasions preceding an URTI episode compared to occasions when the infection did not develop subsequently (within 7 days). However, this parameter was not a specific predictor of URTI, in this cohort of athletes.

Abstract:
The human nasopharynx is a reservoir of both commensal and pathogenic bacteria that can be easily transmitted from one individual to another. It has long been hypothesised that host commensal flora give protection from carriage of pathogens and invasive disease. The commensal Neisseria lactamica has previously been associated with protection against the closely related human pathogen Neisseria meningitidis, which is thought to be due to the acquisition of cross-reactive immunity to N. meningitidis. The objective of this study was to identify the extent of protection by N. lactamica in the absence of host immune cells, using an in vitro model of the human nasopharyngeal epithelium with the Detroit 562 (D562) cell line. N. lactamica has been demonstrated to attenuate the induction of innate inflammatory cytokines and chemokines from D562 cells challenged with N. meningitidis. For the first time in this study, N. lactamica was found to attenuate the induction of IL6, IL8 and TNFα from D562 cells challenged with the unrelated Gram-positive human pathogen Streptococcus pneumoniae. Attenuation by N. lactamica did not extend to suppression of MAPK pathways when stimulated with chemical agonists, but was able to suppress inflammation induced through the intracellular PAMP receptor TLR3, which is not involved in meningococcal or pneumococcal inflammation. This suggests a global mechanism of attenuation in host cells by N. lactamica. N. lactamica was further demonstrated to reduce association with and invasion of D562 epithelial cells by N. meningitidis serogroup B (MenB) by up to 60% and 90%, respectively. This suppression was dependent on live N. lactamica and did not require invasion of host cells by the commensal, suggesting an active mechanism employed by N. lactamica. The occasional human commensal coloniser Neisseria polysaccharea was found to reduce adhesion and invasion of MenB to a similar degree, however the related commensal Neisseria cinerea was not. The reduction in MenB association with host cells protected host cells from MenB-induced apoptosis, which was mediated by activation of caspase 3. This study demonstrates that commensal Neisseria spp. N. lactamica and N. polysaccharea protect the host at the nasopharyngeal epithelium from experimental colonisation and invasive disease by MenB. Additionally, commensal neisseriae protect against inflammation and cell death induced by the unrelated pathogen S. pneumoniae. Therefore, commensal neisseriae warrant further study to evaluate their effectiveness for use as probiotics to protect against bacterial pathogens responsible for meningitis.

Abstract:
Respiratory tract infections (RTI) are responsible for over 4 million deaths per year worldwide. Microbial carriage in the upper respiratory tract is a precursor to respiratory infection and facilitates person-to-person transmission. A large community-based swabbing study was conducted, enabling the collection of a large number of swab samples that would provide key information concerning the epidemiology and ecology of respiratory tract communities. Traditional culture-based techniques, molecular methods and ecological and mathematical modelling methods were used. Participation of members of the community within the swabbing study was shown to be greater within the self-swabbing group, in older individuals and in less deprived locations. Carriage of bacterial and viral species within the respiratory tract was shown to vary with participant age, recent RTI and the presence of other species. Self-taken swabs were largely non-inferior to healthcare professional (HCP)-taken swabs in assessing carriage of the targeted bacteria, offering a cheaper and more flexible alternative to HCP swabbing. Large numbers of capsular types (serotypes), sequence types and low levels of vaccine-targeted types demonstrate the genetic diversity of respiratory bacteria as well as their evolution in response to immunisation. Microbial respiratory community structure was shown to be highly variable with less nested communities and facilitative relationships between species within young individuals and those with recent RTI potentially enhancing transmission and survival of carried species. Neutral and niche processes were both found to be important in respiratory tract community assembly. These insights into respiratory tract communities will allow predictions of microbial variation as a result of infection, varying age and season. Future work will involve 16S rDNA community analysis, further development of ecological methods and the conduction of larger multi-centre carriage studies.

Abstract:
Part I.  Aims: The aims of part I of this research programme were to: measure the prevalence of antibiotic prescription for U.R.T.I. in Primary Health Care Centres in the United Arab Emirates; understand the rational behind antibiotic prescription; Evaluate the effect of different patient characteristics such as self treatment, age, education, occupation and gender; evaluate the effect of physician characteristics such as gender, communication and practice location;  and to evaluate the degree of patient compliance and satisfaction with treatment. Main Conclusions: U.R.T.I. is one of the main reasons for patient visits and antibiotic prescription; physicians’ advice to patients regarding dosage and duration of the prescribed medication was limited; a significant association existed between patients’ expectation from practitioners and practitioners’ perception of patients’ expectations; poor compliance is strongly correlated with poor patient-doctor interaction; diagnoses were typically based on clinical findings; patient satisfaction is strongly linked to the level of communication. Part II.  Aims: To measure the influence of introducing guidelines to doctors and educational leaflets to patients on reducing the level of prescribed antibiotics; and to investigate the effect of factors such as socio-demographic characteristics, signs, symptoms and patient self management. Main Results: The total number of antibiotic prescriptions for patients suffering from U.R.T.I. including sore throat was significantly reduced in the intervention group. Conclusions: A multi-dimensional interventional approach for reducing antibiotic prescription in U.A.E. clinics resulted in a significant positive outcome; and the significant reduction in antibiotic prescriptions indicates the willingness of physicians to follow guidelines and the willingness of patients to respond to educational information. Main Recommendations:  Clinical guidelines are most effective if implemented as part of a systemic strategy, involving dissemination of guidelines by departmental heads and utilisation of computer generated reminders; physicians should be involved as part of the working group to develop guidelines; ongoing educational programmes for physicians; and a public educational campaign on the problem of over use of antibiotics is essential.

Abstract:
Background: Echinacea possibly reduces the effectiveness of corticosteroids, commonly used by asthmatics and for treating viral induced wheeze, and can cause hypersensitivity reactions in susceptible individuals. Treatment of the common cold in children with Echinacea has only been investigated in one randomized, double blind, placebo controlled trial to examine the efficacy and safety of Echinacea purpurea in children with upper respiratory tract infections. This study aimed to investigate the effect Echinacea purpurea herbs in reducing symptoms of upper respiratory infection. Subjects and Method: This was meta-analysis and systematic review. The study was conducted by collecting published articles from PubMed, Science Direct, and Google Scholar databases. The study subject was adults with upper respiratory infection. Intervention was Echinecea purpurea herbs extract with comparison placebo. The study outcome was decreased symptoms of upper respiratory tract infection. The inclusion criteria were full text, using English language, and using randomized controlled trial. The collected articles were selected by PRISMA flow chart. The quantitative data were analyzed using Revman 5.3 Results: A meta-analysis using 6 studies from United States resulted high heterogeneity between experimental groups (I2= 98%; p<0.001), so it conducted by random effect model (REM). This study showed that provision of Echinecea purpurea herbs extract reduced symptoms of upper respiratory tract infection than placebo (Mean Difference= -0.56; 95% CI= -0.91 to -0.22; p= 0.001). Conclusion: Echinecea purpurea herbs extract reduced symptoms of upper respiratory tract infection than placebo.

Abstract:
Abstract Steady airflow pattern during a full breathing cycle in human upper and central respiratory tract was simulated by solving the Navier-Stokes and continuity equations. For ellipsoidal fiber trajectory analysis under cyclic breathing condition, several user defined functions (UDFs) were developed and coupled to the ANSYS-Fluent discrete phase model (DPM). The developed model accounted for solving the coupled translational and rotational equations of motion of ellipsoidal fibers. The airway passage model was extended from the vestibule to the fifth generation of the bronchial bifurcations obtained mostly from computed tomography (CT) scan. A constant flow rate of 15 L/min was used to simulate the normal breathing condition. The velocity and pressure fields for different regions of the respiratory track were evaluated and used for Lagrangian particle trajectory analysis. Total and regional depositions of each region for a range of ellipsoidal particle diameter and aspect ratios were evaluated and the results compared with the experimental data.

Abstract:
Objectives. Uncontrolled seizures in children 1 to 36 months old have serious short-term health risks and may be associated with substantial developmental, behavioral, and psychological impairments. We evaluated the effectiveness, comparative effectiveness, and harms of pharmacologic, dietary, surgical, neuromodulation, and gene therapy treatments for infantile epilepsies. Data sources. We searched Embase®, MEDLINE®, PubMed®, the Cochrane Library, and gray literature for studies published from January 1, 1999, to August 19, 2021. Review methods. Using standard Evidence-based Practice Center methods, we refined the scope and applied a priori inclusion criteria to the >10,000 articles identified. We ordered full text of any pediatric epilepsy articles to determine if they reported any data on those age 1 month to <36 months. We extracted key information from each included study, rated risk of bias, and rated the strength of evidence. We summarized the studies and outcomes narratively. Results. Forty-one studies (44 articles) met inclusion criteria. For pharmacotherapy, levetiracetam may cause seizure freedom in some patients (strength of evidence [SOE]: low), but data on other medications (topiramate, lamotrigine, phenytoin, vigabatrin, rufinamide, stiripentol) were insufficient to permit conclusions. Both ketogenic diet and the modified Atkins diet may reduce seizure frequency (SOE: low for both). In addition, the ketogenic diet may cause seizure freedom in some infants (SOE: low) and may be more likely than the modified Atkins diet to reduce seizure frequency (SOE: low). Both hemispherectomy/hemispherotomy and non-hemispheric surgical procedures may cause seizure freedom in some infants (SOE: low for both), but the precise proportion is too variable to estimate. For three medications (levetiracetam, topiramate, and lamotrigine), adverse effects may rarely be severe enough to warrant discontinuation (SOE: low). For topiramate, non-severe adverse effects include loss of appetite and upper respiratory tract infection (SOE: moderate). Harms of diets were sparsely reported. For surgical interventions, surgical mortality is rare for functional hemispherectomy/hemispherotomy and non-hemispheric procedures (SOE: low), but evidence was insufficient to permit quantitative estimates of mortality or morbidity risk. Hydrocephalus requiring shunt placement after multilobar, lobar, or focal resection is uncommon (SOE: low). No studies assessed neuromodulation or gene therapy. Conclusions. Levetiracetam, ketogenic diet, modified Atkins diet, and surgery all appear to be effective for some infants. However, the strength of the evidence is low for all of these modalities due to lack of control groups, low patient enrollment, and inconsistent reporting. Future studies should compare different pharmacologic treatments and compare pharmacotherapy with dietary therapy. Critical outcomes underrepresented in the literature include quality of life, sleep outcomes, and long-term development.

Evidence Update for Clinicians: Narrow- versus Broad-Spectrum Antibiotics for Common Infections in Children. Patient-Centered Outcomes Research Institute (PCORI), October 2018. http://dx.doi.org/10.25302/eu5.2018.10.

Abstract:
Comparing Narrow- vs. Broad-Spectrum Antibiotics for Common Infections in Children. The choice of antibiotic to treat acute bacterial upper respiratory tract infections in children can affect both symptom resolution and the risk of side effects such as diarrhea and vomiting. The findings of a PCORI-funded study published in JAMA can help clinicians treating children for acute respiratory tract infections (ARTIs)—including acute otitis media, Group A streptococcal pharyngitis, and acute sinusitis—make decisions with parents about the medicine that is best for the child. The study, led by Jeffrey Gerber, a pediatrician and researcher at the Children’s Hospital of Philadelphia, included 30,086 children ages 6 months to 12 years taking narrow- and broad-spectrum antibiotics to treat ARTIs.
