The present study evaluated the utility of heart rhythm coherence (HRC) feedback to reduce the reported pain intensity of patients enrolled in a multimodal pain management program. Participants were recruited and assigned to a usual treatment group (UT) or a heart rhythm coherence feedback group (UT+HRC). It was hypothesized that UT+HRC participants who achieved heart rhythm coherence would report a reduction of pain intensity, as measured by the McGill Pain Inventory. For those whose pain intensity decreased, it was also expected that their self reported levels of depression as measured by the Beck Depression Inventory-Second Edition and state anger as measured by the State Trait Anger Inventory would decrease. It is also hypothesized that with a reduction in pain levels, anger, and depression, blood pressure would also decrease among those who had high blood pressure prior to the intervention. Multivariate analyses of variance (MANOVA) were used to investigate the relationship between treatment condition, coherence status and pain levels. A series of independent t-tests were utilized to investigate the change in pain, depression, and state anger from baseline to posttest, followed by Pearson product moment correlation coefficients on difference scores to understand the relationship between the outcome variables for Hypothesis 2. Standard multiple regression analyses were computed using difference scores to determine if the outcome measures were significant predictors of systolic blood pressure and diastolic blood pressure. Results indicated a failure to reject the null with regard to hypothesis one. No relationship between treatment assignment, coherence status or pain levels were found. Hypothesis 2 was partially supported. Although there was a positive significant relationship between depression and anger when utilizing difference scores, these affective measures were not related to difference scores on either pain measure. In regard to Hypothesis 3, there was also a failure to reject the null. None of the outcome measures utilized in this study emerged as being significantly related to changes in systolic or diastolic blood pressure. Limitations of the study and implications for future research are offered.

A thesis submitted to the Faculty of Health Sciences, University of the Witwatersrand in fulfilment of the requirements for the degree of Doctor of Philosophy. Johannesburg, 2017. / Background Abnormalities of mineral bone disease have been consistently associated with adverse clinical outcomes in patients with chronic kidney disease (CKD). The consequences of these changes have also been shown to differ across races. However, in Africa the impact of derangements of CKD -mineral and bone disorder (CKD-MBD) on patients with CKD is largely unknown. In addition, studies from the USA have reported racial variations in markers of CKD and it remains unclear whether genetic factors may explain this discrepancy in the levels of biochemical markers of CKD-MBD across ethnic groups. Therefore, this study has been conducted to determine the existence of racial differences in the levels of fibroblast growth factor 23(FGF23) and traditional markers of mineral bone metabolism in a heterogeneous African CKD population, and to provide important insights into the pattern and genetic variability of CKD-MBD in sub-Saharan Africa. Methods This was a cross sectional multicenter study carried out from April 2015 to May 2016, involving two hundred and ninety three CKD patients from three renal units in Johannesburg, South Africa. The retrospective arm of this study involved two hundred and thirteen patients undergoing maintenance haemodialysis (MHD) from two dialysis centers in Johannesburg between January 2009 and March 2016. The first part of this study described the pattern of CKD-MBD in MHD patients using traditional markers of CKD-MBD. The second part of the study looked into the spectrum of CKD-MBD and racial variations in markers of CKD-MBD in pre dialysis and dialysis patients. This was followed by the genetic aspect of the study that examined the influence of vitamin D receptor polymorphisms on biochemical markers of mineral bone disorders. Lastly, the study also evaluated the association between markers of CKD-MBD and mortality in MHD patients. Results The prevalence of hyperparathyroidism (iPTH>150 pg/mL), hyperphosphataemia, hypocalcaemia and 25-hydroxyvitamin D deficiency (<30 ng/mL) was 73.4%, 57.0%, 20.3% and 80.7 % respectively in our MHD patients. The combination of markers of bone turnover (iPTH>150 pg/mL and total alkaline phosphatase > 112 U/L) suggestive of high turnover bone disease, was present in 47.3 % of the study population. The odds ratios for developing secondary hyperparathyroidism with hypocalcaemia and hyperphosphataemia were 5.32 (95% CI 1.10 - 25.9, P =0.03) and 3.06 (95 % CI 1.15 - 8.10, P =0.02) respectively. The 293 CKD patients (208 blacks, 85 whites) had an overall mean age of 51.1±13.6 years, and black patients were significantly younger than the white patients (48.4 ±.13.6 versus 57.1±15.5 years; p<0.001). In comparison to whites, blacks had higher median iPTH (498 [37-1084] versus 274[131-595] pg/ml; P=0.03), alkaline phosphatase (122[89-192] versus 103[74-144] U/L; P=0.03) and mean 25- hydroxyvitamin D (26.8±12.7 versus 22.7 ±12.2 ng/ml, P=0.01) levels, while their median FGF23 (100 [34-639] versus 233[80-1370] pg/ml; P=0.002) and mean serum phosphate (1.3±0.5 versus 1.5±0.5, P =0.001) levels were significantly lower. With the exception of vitamin D receptor (VDR) Taq I polymorphism, the distribution of the VDR polymorphisms differs significantly between blacks and whites. In hemodialysis patients, the BsmI Bb genotype was significantly associated with moderate secondary hyperparathyroidism (OR, 3.88; 95 CI 1.13-13.25, P=0.03) and severe hyperparathyroidism (OR, 2.54; 95 CI 1.08-5.96, P=0.03). Patients with high total alkaline phosphatase (TAP) had significantly higher risk of death compared to patients with TAP <112 U/L (hazard ratio, 2.50; 95% CI 1.24–5.01, P = 0.01). Similarly, serum calcium >2.75 mmol/L was associated with increased risk of death compared to patients within levels of 2.10–2.37 mmol/L (HR 6.34, 95% CI 1.40–28.76; P = 0.02). The HR for death in white patients compared to black patients was 6.88; 95% CI 1.82–25.88; P = 0.004. Conclusions Secondary hyperparathyroidism and 25–hydroxyvitamin D deficiency were common in our haemodialysis patients. The study also highlighted the existence of racial differences in the circulating markers of mineral bone disorders in our African CKD population. In addition, the study showed that both moderate and severe secondary hyperparathyroidism are predicted by the BsmI Bb genotype, and the over expression of this genotype in black patients may partly explain the ethnic variations in the severity of secondary hyperparathyroidism in the CKD population. High levels of serum alkaline phosphatase, hypercalcaemia, and white race are associated with increased risk of death in MHD patients. / LG2018

The objective of the study is to analyze the factors associated with the severity of pruritus in patients with terminal chronic kidney disease undergoing hemodialysis. The methodology used is based on a cross-sectional study in patients receiving hemodialysis at the Centro Nacional de Salud Renal. Severe pruritus was defined as a score on the visual analogue scale greater than or equal to 7, and the strength of association with the possible risk factors was assessed by calculating prevalence ratios. Regarding the results, 264 patients were included, 59.9% were male, with a mean time on hemodialysis of 10.26 ± 7.14 years. 75% experienced pruritus, of this group, 1 in 3 presented severe pruritus. Hyperphosphatemia and the use of antihistamines were associated with a higher prevalence of severe pruritus (RP 1.71, 95% CI 1.09-267 and RP 2.39, 95% CI 1.51-3.75, respectively). The positive serology for Hepatitis C Virus was described as a protective factor for presenting severe pruritus (RP 0.55, 95% CI 0.33 - 0.89). In conclusion, severe uremic pruritus is a frequent problem in patients with chronic terminal kidney disease who have hyperphosphatemia and treatment with antihistamines independently of the time they have been on hemodialysis. / Revisión por pares

I performed a secondary analysis of existing data and determined that when interacting with physicians during primary care visits for chronic illness treatment, patients using opioids are less likely to continue presenting concerns designed to reinforce their social and emotional uniqueness during the second half of primary care visits when physicians provide empathic support of their concerns in the first half of visits.

Thesis (M. A. (PHARM.) -- University of Limpopo, 2019 / Introduction Multidisciplinary team (MDT) approach has emerged as one solution to improving chronic kidney disease (CKD) care. The MDT may include a nephrologist, physicians, nurses, dietitians, pharmacists, and social workers, all working together to deliver effective care to patients with CKD. Participation of pharmacists within the renal MDT at Polokwane hospital seems to be limited. The perceived barriers to pharmacists providing renal care services to CKD patients at Polokwane hospital could inform future strategy development, to enhance their participation. The aim of this study was to explore the role of pharmacists in renal care and develop strategies to maximise their participation in the renal multidisciplinary health care team, based on their participation at Polokwane hospital, Limpopo province. Method A qualitative study using semi-structured interviews was conducted with a purposeful sample of 8 members of the renal MDT and 9 pharmacists. The audiotaped interviews were transcribed exactly as said and analysed using thematic content analysis. Results Four themes emerged from the analysis: ‘pharmacist’s current scope of practice within the renal MDT’, ‘potential future roles of pharmacists’, ‘perceived barriers to participation of pharmacists within the renal MDT’ and ‘recommendation/Strategies to incorporate pharmacists into the MDT’. Results have shown that pharmacists have an absent role within the renal MDT. Their role is limited to just dispensing and managing stock, with no role in direct patient care. Both pharmacists and MDT members showed preference to working together during renal care. Pharmacy services suggested include medication reviews, provision of patient education and counselling, patient adherence improvement, dosage workouts, patient monitoring and education on contraindicated drugs and drug interactions. Shortage of staff, pharmacists lack of clinical skills, lack of communication and attitude of pharmacists were perceived as the major barriers to participation of pharmacists within the renal xii MDT. To overcome these barriers, it was recommended that the department of health (DoH) provide more pharmacy staff and educational opportunities in the form of workshops, to equip pharmacists clinically and broaden competency and knowledge on effective communication and coordination. In addition, it was recommended that the clinical curriculum at Universities be revised, to build solid foundation on MDT care and pharmacology and that the MDT programme be standardized through standard treatment guidelines (SOP’s), policies and drawing of job descriptions. Conclusion The role of pharmacists at Polokwane hospital is confined to just stock management and dispensing. There are promising avenues for future development of their role during patient care, which can be achieved by addressing the barriers highlighted Recommendations The expansion of the role of pharmacists within the renal MDT will require improved partnership between health care professionals, resources, legislations and guidance from formal SOPs. Having a national framework for pharmacy practice from Ministry of Health, supported by educational opportunities and a pro-active professional association would be key to incorporating pharmacists within the renal MDT.

Kronisk underlivssmärta hos män är ett vanligt fenomen. Trots detta är ämnet relativtoutforskat, framförallt gällande yngre män. Studiens syfte var att undersöka upplevelser av attleva med denna smärta, hos män i åldrarna 18-40 år. Datainsamling skedde genomsemistrukturerade intervjuer (n = 5), utförda via Skype eller personligt möte. Dataanalyserades genom induktiv tematisk analys. Fem huvudteman utvecklades: “smärtan rubbardet dagliga livet”, “en klassisk man har inte problem där nere”, “smärtan blir något manmåste förhålla sig till”, “hjälpsamt att inte känna sig ensam” samt “vården kantas avosäkerhet”. Tillsammans ger de en bild av männens upplevelser. Resultatet visar att manligunderlivssmärta påverkar många områden i livet samt att det präglas av stigma ochstereotyper. Psykologiska och sociala mekanismer verkar avgörande för att förstå hur manhanterar smärtupplevelsen. Resultatet bekräftar tidigare fynd från studier på äldre män samtbidrar med nya rön från en yngre population. / Chronic pelvic pain is a common phenomena amongst men. Despite this, research on thesubject is still relatively scarce, especially amongst younger men. The aim of this study was toexamine the experience of living with pelvic pain. Data was collected through semi-structuredinterviews (n = 5), via Skype or face-to-face, from a Swedish sample. An inductive thematicanalysis was conducted. Five main themes were developed: “pain disturbs daily life”, “a real man has no problems down there”, “the pain is something you need to relate to”, “helpful tonot feel alone” and “the healthcare is riddled with insecurity”. Together these help summarizemen’s experiences. The results show that chronic pelvic pain affect many areas in everydaylife. It also shows that this pain is characterized by stigma and stereotypes. Psychological andsocial mechanisms seems vital for understanding how coping and pelvic pain relates. Theresults confirm parts from previous research and adds to existing knowledge, but from ayounger and less examined sample.

Chronic obstructive pulmonary disease is the fourth largest cause of death worldwide and the prevalence is predicted to increase even further to make it the third largest cause of death by 2020. The main cause of the disease is exposure to tobacco smoke. COPD is a complex disease and there is a strong need of better understanding of the pathogenetic mechanisms in order to come up with novel therapeutic interventions and preventive strategies. The golden standard to image the lungs today is to use computed tomography (CT) which is an imaging modality that involves ionizing radiation and could thus harm the patient, especially with repeated exposure. New techniques in the image acquisition of magnetic resonance imaging (MRI), an imaging modality that does not involve ionizing radiation, has emerged that allows for lung imaging. The work included segmentation of the lungs, image registration and partitioning of the lungs inorder to perform regional analysis. The results indicate that the mean value of the T1-parameter in the left and right lung is not affected to the same degree, where the left lung showed a greater decrease. The results also showed that the anterior parts of the lungs are not showing any statistically significant changes but the changes were instead seen in the center and posterior parts. Both lungs also showed results that indicate that the mean T1-value is recovered at the end of the longitudinal study, a phenomenon that couldn’t be explained and further studies have to be performed.

People expenencmg chronic pain encounter increases m needs and endure the consequences of failure to satisfy needs. In much of the management of people with chronic pain, chronic pain is considered an abstract phenomenon with little attention given to the human experience. Numerous literature focus on a mechanistic reductionistic approach in management of chronic pain. Most literature is written by medical practitioners, nurses and psychologists from a health-care oriented methodology, whereas minimal research literature was contributed from a pastoral care and counselling perspective. This dissertation explores the needs and feelings of people with chronic pain to identify their needs at the various developmental stages of their pain experience, and within their relevant ecosystems, in order to develop a pastoral response. / Practical Theology / M.

A pele e as mucosas constituem as primeiras barreiras na defesa contra infecções e os macrófagos são componentes essenciais do sistema imune inato, importante neste aspecto. O envolvimento destas células pode ser verificado em grande percentual das imunodeficiências primárias. Desta forma, a avaliação da função fagocitária é de extrema relevância para o reconhecimento dos distúrbios imunológicos que acometem a pele. O objetivo do presente estudo foi avaliar a metodologia laboratorial para a detecção de defeitos funcionais dos fagócitos. Para isto foram estabelecidos os seguintes testes laboratoriais: Nitro Blue Tetrazolium (NBT), Dihidrorodamina (DHR), quimiotaxia, fagocitose e a aderência de S. aureus e C. albicans por citometria de fluxo (CF), além de morte intracelular de S. aureus e C. albicans (CF). Para verificar a integridade do sistema complemento realizou-se ensaios hemolíticos para as vias clássica e alternativa (CH50 e AP50). A metodologia proposta foi aplicada em indivíduos normais para a padronização dos testes. O burst oxidativo avaliado pelo teste da dihidrorodamina (DHR) foi aplicado em 101 indivíduos saudáveis e em paralelo, 50 indivíduos sadios para o teste do NBT. Os mesmos testes foram realizados em pacientes com Candidíase mucocutânea crônica (CMC) (n=9 ), Candidíase persistente (n=5), Suspeita de distúrbios de fagócitos (SDF) (n=14), Doença Granulomatosa Crônica (DGC)(n= 7) e portadores de DGC (n=5). A quimiotaxia foi padronizada em 34 controles para neutrófilos estimulados com Lipopolissacarídeo de E.Coli (LPS) e 5 com fungo Candida albicans. A técnica de fagocitose e aderência de patógenos foi padronizada com os mesmos estímulos (n=7 para fungos/n=5 para bactéria). Após a padronização, o ensaio foi aplicado em pacientes com candidíase persistente (n=5 para bactéria e n=5 para fungo) e em pacientes com CMC (n= 3 para bactéria e n=4 para fungo). Os ensaios de fagocitose e morte intracelular (capacidade bactericida e fungicida) foram padronizados em 18 indivíduos sadios para bactérias e os ensaios de morte intracelular para S. aureus foi aplicado em pacientes com CMC (n=5), com CP (n=6), com SDF (n =9) e com DGC (n=2), para os ensaios de fagocitose com morte intracelular para fungos foram utilizados 22 indivíduos saudáveis e após a padronização do ensaio foram aplicados em pacientes com CMC (n=8), pacientes com CP ( n= 7), pacientes com DGC (n=2) e indivíduos com SDF (n= 13) O ensaio de DHR foi padronizado e estabelecido em 80% de intensidade de fluorescência para células estimuladas com PMA e 15% de intensidade de fluorescência para células sem estímulo. Nos resultados do DHR encontrou-se diferença significativa no grupo de DGC (n=7)(P= 0,0001), no grupo de portadores (n=5)(P=0,0005) e no grupo de SDF (n=14)(P= 0,0053). O ensaio do DHR foi repetido após 24 horas da coleta (n=7), não se verificando alteração da resposta. A quimiotaxia mostrou diferença significativa entre C (n=4) vs SDF (n=3)(P=0,0001) e pacientes com CMC apresentaram redução da capacidade quimiotática para bactérias (n=3)e fungos (n= 4) com soro autólogo (P= 0,0246 e P=0,0109, respectivamente). Na fagocitose e aderência de bactérias inativadas ,os grupos de CMC, CP E SDF não mostraram diferenças significativas com bactérias não opsonizadas ou opsonizadas com soro AB e apresentaram menor índice de fagocitose (C x CMC)(P=0,0357) quando foram opsonizadas com soro autólogo. Na fagocitose e aderência de fungos inativados, controles e grupos de pacientes apresentaram resposta semelhante com fagocitose preservada. Os ensaios de morte intracelular para bactérias não opsonizadas houve menor expressão de fagocitose no grupo de C x SDF (P=0,0044). Na capacidade bactericida verificou-se diferença significativa entre os grupos CxCMC (P=0,0403). A opsonização das bactérias com soro AB foi significativamente diferente entre os grupos CxCP (P=0,0129) e CxSDF (P=0,0048) e com capacidade bactericida diferente entre grupos CxCP (P=0,0258) e CxSDF (P=0,0205). Na avaliação da fagocitose de bactérias opsonizadas com soro autólogo foi verificada diferença significativa entre os grupos CxCP (P=0,0013) e CxSDF (P=0,0048). Não houve diferença na capacidade bactericida dos grupos de pacientes com o controle. Os ensaios de fagocitose e morte intracelular para fungos sem opsonização não mostrou diferença estatisticamente significativa. A morte intracelular mostrou-se diferente para o grupo CxCMC (P=0,0155) e quando opsonizado com soro AB houve diferença CxCP (P=0,0369). A fagocitose com opsonização por soro autólogo significativa no grupo CxSDF (P=0,0001) e um paciente de CMC com sua fagocitose comprometida quando comparado com o controle do dia. A morte intracelular foi diferente nos grupos CxCMC (P=0,0018) e CxCP (p=0,0203). Não houve diferença estatisticamente significativa à avaliação do complemento. O ensaio do DHR mostrou ser sensível e preciso para o diagnóstico de DGC e portadores de DGC, porém pode detectar outras alterações de fagócitos. O ensaio de aderência e fagocitose mostraram-se variáveis dificultando a padronização de valores de normalidade e exclusão de defeitos. Ensaios de fagocitose com morte intracelular mostraram-se como a melhor forma de detectar distúrbios de fagócitos além do diagnóstico de DGC. A aplicação de controles do dia mostrou-se necessária e importante para a detecção de defeitos funcionais. O presente trabalho mostrou que a avaliação de distúrbios de fagócitos por morte intracelular por citometria de fluxo pode ser aplicado em outras situações clínicas com comprometimento imunológico / Skin and mucosa are part of the first barriers in the defense against infections, and the macrophages are essential components of the innate immune system, important when related to this aspect. The involvement of these cells can be seen in a large percentage of the primary immunodeficiencies. Therefore, the assessment of the phagocitary function is extremely important for the recognition of immunological disorders which affect the skin. The present study focus on the evaluation of the laboratorial methodology for the detection of functional defects of phagocytes. For this the following laboratorial tests were established: Nitro Blue Tetrazolium (NBT), chemotaxis, phagocytosis and adherence of S. aureus and C. albicans through flow cytometry (FC), besides the intracellular death of S. aureus and C. albicans (FC). To assess the integrity of the complement system hemolytic assays were performed for the classic and alternative pathways (CH50 and AP50). The proposed methodology was applied to normal individuals for the standardization of the assays. The oxidative burst evaluated through the dihydrorodamine essay (DHR) was applied to 101 healthy individuals and in parallel, 50 healthy individuals for the NBT assay. The same assays were performed on patients with Chronic mucocutaneous candidiasis (CMC)(n=9), persistent candidiasis (n=5), Phagocytes disorders suspicious (PDS) (n=14), Chronicle granulomatous disease (CGD)(n=7) and CGD carriers (n=5). Chemotaxis was standardized using 34 controls for neutrophils stimulated by lipopolisacharydes from e. coli (LPS) and 5 by C. albicans. Phagocytosis and adherence of pathogens were standardized using the same stimuli (n=7 for fungi and n=5 for bacteria). Following the standardization, the assay was applied to patients with persistent candidiasis (n=5 for fungi and n=5 for bacteria) and on patients with CMC (n=4 for fungi and n=3 for bacteria). Phagocytosis and intracellular death assays (bactericidal and fungicidal capacity) were standardized using 18 healthy individuals for bacteria and the intracellular death assays for S. aureus were applied on patients suffering from CMC (n=5), from PC (n=6), from PDS (n=9) and from CGD (n=2), for the phagocytosis with fungi intracellular death assays 22 healthy individuals were used, and following the standardization the assay was applied to patients suffering from CMC (n=8), from PC (n=7), from CGD (n=2) and PDS individuals (n=13). The DHR assay was standardized and established according to fluorescence intensity 80% for cells stimulated by PMA and fluorescence intensity 15% for cells without stimuli. In the DHR results a significant difference in the CGD group (n=7)(P= 0,0001), in the carriers group (n=5)(P=0,0005) and in the PDS group (n=14)(P= 0,0053) was found. The DHR assay was performed once again 24 hours after the sample collection (n=7) and no changes in the response were seen. Chemotaxis showed a significant difference between C (n=4) vs PDS (n=3)(P=0,0001) and patients suffering from CMC showed decreased ability in the chemotaxis of bacteria (n=3) and fungi (n=4) with autologous serum (P= 0,0246 e P=0,0109, respectively). In the phagocytosis and adherence of inactivated bacteria, the CMC, PC and PDS groups showed no significant differences with non-opsonizated bacteria or opsonizated with AB serum and presented a lower phagocytosis level (C x CMC)(P=0,0357) when they were opsonizated by autologous serum. In the phagocytosis and adherence of inactivated fungi, controls and patient groups presented a similar response with preserved phagocytosis. In the intracellular death assays for non-opsonizated bacteria there was a lower phagocytosis expression in the C x SDF group (P=0,0044). In the bactericidal ability a significant difference between the groups C x CMC was seen (P=0,0403). The opsonization of bacteria with AB serum showed a significant difference among the groups C x CP (P=0,0129) and C x SDF (P=0,0048) and with different bactericidal ability among the groups C x CP (P=0,0258) and C x SDF (P=0,0205). In the evaluation of the phagocytosis of bacteria opsonizated by autologous serum a significant difference among the groups C x CP (P=0,0013) and C x SDF (P=0,0048) was seen. There was no difference between the bactericidal ability of the patients group and control group. The phagocytosis and intracellular assays for fungi without opsonization presented no significant statistical difference. Intracellular death was different for the C x CMC group (P=0,0155) and when opsonizated by AB serum difference was shown C x CP (P=0,0369). The phagocytosis with opsonization by autologous serum presented significant difference in the C x SDF group (P=0,0001) and in a CMC patient with compromised phagocytosis when compared with the daily control. Intracellular death was different in the C x CMC (P=0,0018) and C x CP (p=0,0203) groups. There was no significant statistical difference according to the complement evaluation. The DHR assay was seen as very sensitive and precise for the diagnosis of CGD, however it can detect other phagocyte alterations. The phagocytosis and adherence assay varied a lot making the standardization of normal values and defects exclusion very difficult. Phagocytosis with intracellular death assays showed the best performance to detect phagocytes disorders besides CGD diagnosis. The use of daily controls was seen as very necessary and important to detect functional disorders. This study demonstrated that phagocytes disorder evaluation through intracellular death using flow cytometry can be applied to other clinical situations which are immunologically compromised
