Optimal pharmacotherapy requires an understanding of the dose-exposure (pharmacokinetics or PK) to response (pharmacodynamic or PD) relationship. Little is known about the influence of obesity on this dynamic system as PK studies in obesity have been largely descriptive rather than explanatory. This has led to a paucity of dosing guidelines for the obese, and arbitrary dose selection in the clinic. There is a need to quantify the impact of obesity on drug clearance (CL) to ensure that exposure is matched across patients of different body compositions, thereby improving therapeutic outcomes and minimising adverse events. The global aim of this thesis was to use prior published data and new clinical trial data to understand how body composition impacts upon drug CL and renal function, and to determine how clinical study design influences the identification of these relationships. Chapter 2 of this thesis determined if conventional body size descriptors that have been used to scale drug doses to body size were appropriate. In the clinical setting, a body size descriptor commonly used for determining dose requirements is total body weight (WT), based on the assumption that physiological function and PK parameters vary according to body size. However, dosing algorithms based on WT might be unsuitable for the obese due to their altered body composition which, if inaccurate, could ultimately lead to overdoses. Alternative body size descriptors such as body surface area and ideal body weight have been used, but are limited when extrapolated to obese patients as they do not take into account the covariates required to describe differences in body composition between individuals. In contrast, it was demonstrated that lean body weight (LBW), as derived by Janmahasatian et al, had the potential to scale CL across a wide range of body compositions. This literature review and systematic analysis of previously published obesity data led to the proposal of a hypothesis that body composition is sufficient to explain the influence of obesity on drug CL and that dosing for obese patients should be based on LBW. When conducting clinical studies, the selection of an appropriate body size descriptor for scaling doses across individuals of different body compositions can be aided by a study design that allows for the identification of parameter-covariate relationships which are transportable to the obese. Chapter 3 of this thesis quantified the probability of identifying these parameter-covariate relationships as a function of differing study designs. Demographics were generated using a multivariate lognormal covariate distribution with truncation at different WT limits under both a non-stratified and stratified design. PK data were simulated from a 1-compartment, first order input, first order elimination model with LBW as the covariate on CL, termed the ‘True Model’. The ‘False Model’ had WT as the covariate on CL. Both models were fitted to the simulated data and the preferred model was selected based on the difference in objective function values. Each design was evaluated under differing magnitudes of random effects, as well as under a D-optimal sparse sampling scheme. It was shown under a simulation platform that the use of stratification and a wide covariate range enhanced the probability of selecting the true covariate from two competing covariate models. The aforementioned findings regarding LBW and stratification were used to design a new clinical study investigating the influence of obesity on renal drug elimination pathways. This work forms Chapters 4 and 5 of this thesis. Non-obese and obese healthy volunteers were recruited using a study design stratified for LBW. These subjects were administered a combination of four renal markers for the simultaneous assessment of various renal processes. One of the renal markers was para-aminohippuric acid (PAH), which provides an estimation of renal plasma flow (RPF). A population PK model was developed for PAH, which revealed that body size alone was insufficient to explain variability in RPF across healthy individuals of a large range of body compositions, although LBW emerged as the preferred covariate (p=0.053) among the body size descriptors tested. This weak covariate effect was in contrast with prior research supporting the use of LBW in normalising the effect of obesity on glomerular filtration rate (GFR), implying that body composition could play a greater role in influencing GFR than RPF. This thesis has applied new methods to the design of drug CL studies in obesity, and offered results and future directions to maximise the information gained from such clinical studies. A better understanding of alterations in PK and physiological function arising from changes in body composition should aid in optimising dose adjustments for obese patients, which is of great importance given the increasing prevalence of obesity in today’s society.

The large-scale field-systems, ubiquitous across upland and marginal parts of the Yorkshire Dales, are insecurely dated and poorly understood. Apart from some sporadic academic interest, the archaeology of this region has yet to receive the level of scholarly attention it deserves. The research presented here involved an intensive investigation of an area near Grassington, Upper Wharfedale, UK. Detailed field analysis revealed a section of one of these field-systems to be only a single element in a complex, multi-layered prehistoric landscape, which it is proposed may have roots as far back as the early Neolithic. Contextualisation of the survey area against palynological data, radiocarbon dates and comparative material moves the date of inception of the field-systems back to the middle Bronze Age, some 1000 years earlier than is currently assumed. The combination of empirical data and theoretical ideas has allowed a relative chronology to be determined in the survey area, together with the creation of a testable hypothesis surrounding the development of Upper Wharfedale and the wider Yorkshire Dales through prehistory. A sense of place and the veneration of natural places are key themes within this landscape and it was possible through these to draw out elements of prehistoric society and to show the evolution of ideas such as land tenure and monument significance. This dual empirical-theoretical approach is novel in upland landscape archaeology in the UK and is shown here to have significant merit.

The kidneys have a significant role in drug elimination through both metabolic and excretory routes. Despite a recent paradigm shift towards systems pharmacology approaches, prediction of renal drug disposition using 'bottom-up' and mechanistic modelling approaches remains underdeveloped. Lack of 'gold-standard' in vitro assays and corresponding in vitro-in vivo extrapolation (IVIVE) approaches for prediction of renal metabolic (CLR,met) and excretory (CLR) clearances contribute to this. A comprehensive literature analysis of quantitative physiological data to inform renal IVIVE scaling factors and systems parameters relevant for physiologically based pharmacokinetic (PBPK) kidney models was initially performed to identify existing knowledge gaps. Following this, microsomal protein content in dog kidney cortex (MPPGK) and liver (MPPGL) were measured in 17 samples from the same animal. Mean dog MPPGK (44.0 mg/ g kidney) and MPPGL (63.6 mg/ g liver) obtained using glucose-6-phosphatase activity as the microsomal protein marker where systematically higher than when CYP content was used as the marker (33.9 mg/ g kidney and 41.1 mg/ g liver respectively). Dog MPPGK was lower than MPPGL, with no direct correlation between the organs. In addition to dog, MPPGK and cytosolic protein per gram kidney (CPPGK) were obtained from 31 human samples, which represent the largest dataset currently available. Mean human MPPGK (25.7 mg/ g kidney) and CPPGK (52.7 mg/ g kidney), were measured using glucose-6-phosphatase and glutathione-S-transferase activities as recovery markers, respectively. Activity of prepared kidney microsomes was assessed using mycophenolic acid glucuronidation as a marker. Novel scaling factor of 25.7 mg/ g kidney was applied for IVIVE of mycophenolic acid microsomal glucuronidation data, resulting in a 2-fold increase in scaled intrinsic clearance compared with data scaled by the commonly used literature MPPGK value (12.8 mg/ g kidney). In addition to the microsomal scaling factor, several elements of a modified stereology method were developed for quantifying human proximal tubule cellularity. The methods included implementation of a systematic uniform random sampling protocol and investigation of tinctorial and immunohistochemistry based staining approaches that could be used identify and count proximal tubule cells in histology sections. A range of mechanistic models for prediction of CLR via either tubular reabsorption or active secretion were developed. A novel 5-compartment model for prediction of tubular reabsorption and CLR from Caco-2 apparent permeability data was developed. This model accounted for relevant physiological complexities of the kidney, such as regional differences in tubular filtrate flow rates and tubular surface area, including consideration of the impact of microvilli. The model predicted the CLR of 45 drugs with overall good accuracy (geometric mean fold error of 1.96), although a systematic under-prediction was noted for basic drugs. The novel 5-compartment model represents an important addition to the IVIVE toolbox for physiologically-based prediction of renal tubular reabsorption and CLR and can be implemented in the more complex mechanistic kidney models, as shown in the case of prediction of urine flow dependent CLR of theophylline and caffeine. Final part of the Thesis focused on the refinement of digoxin PBPK kidney model and its ability to predict effect of aging and renal impairment on digoxin CLR. The analysis has identified that reducing either the proximal tubule cellularity or OATP4C1 abundance parameters in the mechanistic model recovers well observed reduced tubular secretion and CLR of digoxin in renal impairment populations whereas no effect of modification of P-gp abundance was observed. Conversely, reducing the proximal tubule cellularity, OATP4C1 abundance or P-gp abundance parameters in the model resulted in negligible change, decreased or increased accumulation of digoxin in proximal tubule cells, respectively. In conclusion, the current study provides to date the most comprehensive kidney microsomal and cytosolic metabolic scaling factors, together with revised database on renal physiological data necessary for quantitative prediction of renal drug disposition. Mechanistic modelling work shown here has highlighted a need for physiological data from different population groups to inform kidney model parameters, in order to improve the scope and utility of such models within the systems pharmacology paradigm.

Justificativa: Doses inadequadas de diálise estão associadas a maior morbidade e mortalidade em pacientes com uremia terminal em tratamento hemodialítico. Atualmente os métodos mais utilizados para medir a adequação da hemodiálise baseiam-se no cálculo da depuração fracional de uréia (Kt/V) e da taxa de redução da uréia (URR). Nesse estudo avaliou-se a reprodutibilidade do Kt/V e da URR e analisou-se o número aceitável de medidas mensais destes parâmetros para determinar de forma fidedigna a adequação da hemodiálise. Métodos: Avaliamos 43 pacientes clinicamente estáveis, em cinco sessões de hemodiálise (sessões 1 a 5), durante três semanas. Três diálises consecutivas na primeira semana (sessões 1, 2, 3) e duas sessões de meio de semana, nas duas semanas subseqüentes (sessões 4 e 5). Resultados: Não houve diferença entre a média dos Kt/Vs obtidos em diálises seqüenciais (1, 2 e 3) comparada a média dos Kt/Vs obtidos em diálises no meio da semana (2, 4 e 5). O mesmo aconteceu com a URR e com os coeficientes de variação do Kt/V e da URR. Também não encontramos diferença entre uma medida mensal (Kt/V 2) e três medidas mensais (média dos Kt/Vs 2, 4 e 5). O mesmo ocorreu com a URR. A diferença entre o Kt/V 2 e a média dos Kt/Vs 2, 4 e 5 foi de – 0,02 unidades e entre a URR 2 em relação a média das URRs 2, 4 e 5 foi de – 0,5%. Além disso, se fizermos apenas uma medida mensal (Kt/V 2) 80% dos pacientes estarão a uma distância de no máximo 0,16 unidades abaixo da média dos Kt/Vs 2, 4 e 5 e no máximo 0,12 unidades acima. Em relação a URR 80% dos pacientes estarão a uma distância de no máximo 4,37% abaixo da média das URRs 2, 4 e 5 e no máximo 3,37% acima. O grau de concordância entre o Kt/V 2 e a média dos Kt/Vs 2, 4 e 5 é bom para pontos de corte do Kt/V igual ou superior a 1,3. No caso da URR a concordância é boa para pontos de corte acima de 65%. Conclusão: Concluímos que nesta população de pacientes clinicamente estáveis os parâmetros de adequação da hemodiálise mostraram-se reprodutíveis não havendo necessidade de aumentar o número de medidas mensais da quantidade de diálise ofertada. / Background: Inadequate doses of dialysis are associated with higher morbidity and mortality rates for end-stage renal disease (ESRD) patients undergoing hemodialysis treatment. Most methods aimed at measuring dialysis adequacy use the calculation of fractional clearance of urea (Kt/V) and urea reduction ratio (URR). This study evaluates the reproducibility of Kt/V and URR and analyzes the acceptable number of monthly measurements of these parameters to determine hemodialysis adequacy. Methods: We evaluated 43 clinically stable patients in five hemodialysis sessions (1 to 5) along three weeks. Three consecutive sessions were carried out in the first week (1, 2, 3), while the two other studied sessions were carried out in the middle of the week at weekly intervals (4, 5). Results: There was no difference between mean Kt/V in sessions 1, 2, and 3 and in sessions 2, 4, and 5. The same was observed for URR and the coefficients of variation for Kt/V and URR. Either differences were found between one monthly measurement (2) or three monthly measurements (mean of 2, 4, and 5) for Kt/V and URR. The difference between Kt/V 2 and the arithmetic mean of Kt/Vs 2, 4, and 5 was – 0.02 units, and between URR 2 and the mean of URRs 2, 4, and 5 was – 0.5%. When only one monthly measurement (Kt/V 2) was considered, 80% of the patients presented ≤0.16 unit below or ≤0.12 above the mean of Kt/Vs 2, 4, and 5. For URR, 80% of patients presented ≤4.73% below or ≤3.37% above the arithmetic mean of URRs 2, 4, and 5. The degree of agreement between Kt/V 2 and the mean of Kt/Vs 2, 4 and 5 is good for Kt/Vs of 1.3 or higher. URR agreements are good for URR of 65% or higher. Conclusion: In this population, hemodialysis adequacy parameters were reproducible, and an increase in the number of monthly measurements seems not to be necessary.

Base teórica: Muitos pacientes internados em Unidade de Terapia Intensiva (UTI) necessitam da instituição da ventilação mecânica invasiva (VM). Porém esta pode trazer efeitos deletérios como: alteração na higiene brônquica e pneumonia associada à ventilação mecânica (PAV). Devido a isso, faz-se necessária avaliação de técnicas de higiene brônquicas eficazes e o menos deletérias possíveis. Objetivos: Comparar a eficácia das técnicas em estudo: vibrocompressão (VB) (G1), hiperinsuflação com o ventilador mecânico (HMV) (G2) VB + HMV (G3) na quantidade de secreção aspirada (SEC), no tempo de VM, na incidência de PAV, na reintubação orotraqueal (Re-IoT) e na mortalidade de pacientes em VM. Método: Ensaio clínico randomizado, realizado no Centro de Terapia Intensiva do Hospital de Clínicas de Porto Alegre (HCPA). Foram incluídos no estudo 93 pacientes (29 G1, 32 G2 e 32 G3) em VM por mais de 24 horas. Foram aplicadas as seguintes técnicas: aspiração isolada (ASP), VB, HMV e VB + HMV. Foram medidas as seguintes variáveis: frequência cardíaca (FC), frequência respiratória (FR), pressão arterial média (PAM), saturação arterial periférica de oxigênio (SpO2), pressão inspiratória de pico (PIP), volume corrente (VC), complacência dinâmica (Cdyn), peso da SEC; tempo de VM, Re-IoT, incidência de PAV e mortalidade na VM. Conclusão: O grupo 3 foi o único que apresentou aumento significativo da SEC, quando comparado à ASP (0,7 g (0,1-2,5) vs 0,2 g (0,0-0,6) – p = 0,006). Em comparação com os demais grupos, o grupo 2 apresentou aumento significativo na incidência de PAV (22% - p = 0,003) e Re-IoT (21,9% - p = 0,048), demonstrando assim, na amostra estudada, que VB + HMV é mais eficaz quanto à quantidade de SEC e exerce efeito protetor, juntamente com a VB, na incidência de PAV e Re-IoT. / Background: Many patients admitted to the Intensive Care Unit (ICU) require the institution of invasive Mechanical Ventilation (MV). However, this can bring harmful effects such as changes in mucociliary transport and cough capacity, leading to bronchial obstruction and Ventilator Associated-Pneumonia (VAP). Objective: To compare the efficacy of the techniques: Vibrocompression (G1), Hyperinflation with Mechanical Ventilation (G2) Vibrocompression + Hyperinflation with Mechanical Ventilation (G3) in the amount of Aspirated Secretions (AS), MV time, the incidence of VAP, Re-intubation tracheal (Re-IoT) and mortality of patients on MV. Method: Randomized clinical trial, conducted at the Intensive Care Unit, of the Hospital de Clinicas de Porto Alegre (HCPA). 93 patients were included in the study (29 G1, 32 G2 and 32 G3) in mechanical ventilation for more than 24 hours. The following techniques were applied: Isolated Aspiration (ASP), Vibrocompression (VB), Hyperinflation with Mechanical Ventilation (HMV) Vibrocompression + Hyperinflation with Mechanical Ventilation (HMV + VB). The following variables were measured: Heart Rate (HR), Respiratory Rate (RR), Mean Arterial Pressure (MAP), Peripheral Arterial Oxygen Saturation (SpO2); Peak Inspiratory Pressure (PIP), Tidal Volume (TV); Dynamic Compliance (Cdyn); weight of the AS; VM time; Re-IoT; VAP incidence and mortality in the VM. Conclusion: The HMV + VB (G3) was the only group that showed significant increase in the AS (0.7 g (0.1-2.5) vs 0.2 g (0.0-0.6) – p = 0.006) when compared to ASP. Compared with the other groups G2 showed a significant increase in the incidence of VAP (22% - p = 0.003) and Re-IoT (21.9% - p = 0.048). Thus demonstrating in the sample, which HMV + VB is more effective as the amount of secretion aspirated and has a protective effect, along with the VB, the incidence of VAP and Re-IoT.
