Abstract:

Feline upper respiratory tract aspergillosis (URTA) is a recently characterised condition most commonly reported in apparently immunocompetent cats. The hypothesis of this thesis is that cats with URTA have a genetic abnormality in their innate immune response that allows colonisation and invasion of the sinonasal mucosa by the Aspergillus spp. The overall aim was to investigate the innate immune system in cats with URTA. Sinonasal mucosal leucocyte populations where characterised using immunohistochemistry. Significantly more immunoglobulin-expressing cells were identified in affected cats w

Abstract:

Abstract Acute rhinosinusitis is estimated to be one of the most common diseases in childhood. Still, the diagnostics and clinical relevance of this disease are controversial. Bacterial rhinosinusitis cannot be differentiated from mere rhinitis on clinical grounds alone. Abnormal radiologic findings have been found to be common in child and adult volunteers without sinus symptoms and in adults during viral upper respiratory infection. In children, the results of the few placebo-controlled studies on the benefit of antimicrobial treatment of clinically diagnosed acute rhinosinusitis are contro

Abstract:

The physiological responses to upper-body exercise (UBE) are well established. Few published studies, however, have attempted to elucidate the mechanical ventilatory responses to UBE. There is empirical evidence that respiratory function may be compromised by UBE during which the ventilatory and postural functions of the ‘respiratory’ muscles may be exacerbated. Therefore, the aims of this thesis were: 1) to characterise the mechanical-ventilatory responses to UBE in healthy subjects; 2) to explore the putative mechanisms that underpin the respiratory responses to UBE; and 3) to assess whether

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

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 e

Snoring is common in pregnancy, and has been associated with an increased incidence of both maternal hypertension and preeclampsia, as well as an increased incidence of low birth weight infants and significantly poorer Apgar scores at birth. Patients with pre-eclampsia have episodes of partial upper airway (UA) obstruction during sleep. These repeated episodes are associated with further increases in blood pressure (BP). Preliminary evidence indicates that preventing episodes of airflow obstruction with continuous positive airway pressure (CPAP) therapy may reduce BP in pre-eclampsia. Snoring

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 abse

Abstract:

Prevalence of the common nasopharyngeal colonisers, S. pneumoniae, S. pyogenes, N. meningitidis, M. catarrhalis, H. influenzae and S. aureus depends on several factors. The aim was to explore associations between viral infections (URTI) and prevalence and density of bacteria in the nasopharynx, first in an observational cohort study (2011-12) and subsequently in a randomised, laboratory blinded intervention study (2012-13) using nasal flu vaccine (LAIV). Quantitative PCR (qPCR) assays were developed and validated to efficiently detect and quantify target organisms. 161 healthy children were re
