Background: The incidence of nonmelanomatous skin cancer (NMSC) is substantially higher among renal transplant recipients (RTRs) than in the general population. With a growing RTR population, a robust method for monitoring skin cancer rates in this population is required.
Methods: A modeling approach was used to estimate the trends in NMSC rates that adjusted for changes in the RTR population (sex and age), calendar time, the duration of posttransplant follow-up, and background population NMSC incidence rates. RTR databases in both Northern Ireland (NI) and the Republic of Ireland (ROI) were linked to their respective cancer registries for diagnosis of NMSC, mainly squamous cell carcinoma (SCC) and basal cell carcinoma (BCC).
Results: RTRs in the ROI had three times the incidence (P<0.001) of NMSC compared with NI. There was a decline (P<0.001) in NMSC 10-year cumulative incidence rate in RTRs over the period 1994–2009, which was driven by reductions in both SCC and BCC incidence rates. Nevertheless, there was an increase in the incidence of NMSC with time since transplantation. The observed graft survival was higher in ROI than NI (P<0.05) from 1994–2004. The overall patient survival of RTRs was similar in NI and ROI.
Conclusion: Appropriate modeling of incidence trends in NMSC among RTRs is a valuable surveillance exercise for assessing the impact of change in clinical practices over time on the incidence rates of skin cancer in RTRs. It can form the basis of further research into unexplained regional variations in NMSC incidence.

BACKGROUND: It is now common for individuals to require dialysis following the failure of a kidney transplant. Management of complications and preparation for dialysis are suboptimal in this group. To aid planning, it is desirable to estimate the time to dialysis requirement. The rate of decline in the estimated glomerular filtration rate (eGFR) may be used to this end.

METHODS: This study compared the rate of eGFR decline prior to dialysis commencement between individuals with failing transplants and transplant-naïve patients. The rate of eGFR decline was also compared between transplant recipients with and without graft failure. eGFR was calculated using the four-variable MDRD equation with rate of decline calculated by least squares linear regression.

RESULTS: The annual rate of eGFR decline in incident dialysis patients with graft failure exceeded that of the transplant-naïve incident dialysis patients. In the transplant cohort, the mean annual rate of eGFR decline prior to graft failure was 7.3 ml/min/1.73 m(2) compared to 4.8 ml/min/1.73 m(2) in the transplant-naïve group (p < 0.001) and 0.35 ml/min/1.73 m(2) in recipients without graft failure (p < 0.001). Factors associated with eGFR decline were recipient age, decade of transplantation, HLA mismatch and histological evidence of chronic immunological injury.

CONCLUSIONS: Individuals with graft failure have a rapid decline in eGFR prior to dialysis commencement. To improve outcomes, dialysis planning and management of chronic kidney disease complications should be initiated earlier than in the transplant-naïve population.

BACKGROUND: Cyclosporin A is used extensively to prevent the rejection of allogenic renal transplants. However, it is associated with a variety of undesirable side effects including gingival overgrowth. Tacrolimus (FK506), has been marketed as an effective alternative immunosuppressant to cyclosporin A and recent subjective reports suggest patients taking it complain infrequently of gingival problems. This clinical investigation was undertaken to confirm whether or not tacrolimus adversely affected the gingival health of renal transplant recipients.

METHODS: Renal transplant patients (RTPs) under the care of the Renal Transplantation Service at the Manchester Royal Infirmary, who had received a renal allograft at least 18 months earlier, were recruited for this study. All but one of the RTPs had been taking tacrolimus since transplantation. The other had commenced tacrolimus therapy two months after receiving her allograft. A hospital based control group was recruited from non transplanted individuals attending the Turner Dental School, Manchester. Each patient underwent a detailed dental assessment and had dental impressions taken. The extent of gingival overgrowth was determined from plaster models.

RESULTS: 25 renal transplant recipients and 26 control patients were included in the study. None of the individuals in either the tacrolimus or control groups had clinically significant overgrowth. The patients in the tacrolimus group with the highest overgrowth scores were those also taking calcium antagonists as treatment for hypertension.

CONCLUSION: This study demonstrates that tacrolimus has no adverse effects on the gingival tissues and thus has potential as an alternative immunosuppressant for individuals susceptible to developing cyclosporin A-induced gingival overgrowth.

RESUMO: O transplante hepático ortotópico é uma terapêutica aceite para casos selecionados de falência hepática terminal. O procedimento tem-­‐se aperfeiçoado, evidenciado pelo aumento da taxa de sobrevida de 30 para 75% aos 5 anos, mas cerca de 13 a 27% dos enxertos desenvolve falência primária (PNF) ou disfunção primária (DF) após o transplante. As consequências são devastadoras para a sobrevida do doente e do enxerto. A sua etiologia é multifactorial, incluindo factores relacionados com o dador e o receptor, tempos de isquémia, agressões cirúrgicas, bem como características anatomopatológicas do enxerto. A lesão de isquémia/reperfusão mantem-­‐se como um factor de risco intra operatório, com implicações directas sobre toda a evolução do transplante : existe uma relação íntima entre a PNF e a DF, a preservação do enxerto, a lesão de isquémia/reperfusão, e a falência do transplante. Além disso, está comprovada evidência que sugere que a lesão de I/R torna um aloenxerto mais vulnerável por aumento da imunogenicidade, aumentando a probabilidade de episódios de rejeição precoce e tardia. Com base na prática clínica quotidiana do CHBPT HCC, estudaram-­‐se 54 casos de transplante hepático, agrupados segundo grupos por alocação do enxerto respectivo: Grupo 1(n=27): dador cadáver para receptor cirrótico, Grupo 2 (n=15): dador cadáver para receptor PAF, Grupo 3 (n=12): dador PAF para receptor cirrótico. Observaram-­‐se as alterações histológicas e moleculares sobre o enxerto até ao final da operação do receptor, e as suas consequências clínicas,avaliando: -­‐ As diferentes capacidades de resistência e cada enxerto à lesão de isquémia/reperfusão. -­‐ As situações em que os factores do receptor se sobrepõem às do enxerto na definição do prognóstico, e vice versa. -­‐ A relevância das lesões histológicas e moleculares precoces no tecido hepático na evolução do enxerto e do receptor. Foram colhidas biópsias por agulha dos 54 enxertos hepáticos,42 provenientes de cadáver com coração batente(morte cerebral) e 12 provenientes de dador vivo com PAF, em três tempos diferentes do processo de colheita e transplante hepático: ­‐ A primeira(T0)antes da clampagem da aorta do dador -­‐ A segunda (T1) no final da isquémia fria -­‐ A terceira (T2) após a reperfusão do enxerto, durante o encerramento da parede abdominal. A estas amostras foi extraído RNA total, convertido em cDNA por transcrição reversa e feita a análise da expressão dos genes da CTLA4, IL-­‐1β, IL-­‐4, IL-­‐6, IL-­‐13, TNF-­‐α, Perforina, Selectina, (SELE), Fas-­‐ligando, Granzima-­‐B, Heme-­‐Oxigenase 1(HO1)e Óxido Nítrico Sintetase(iNOS2A)por PCR quantitativo segundo o método do Ct comparativo, utilizando como referência a expressão dos genes da amostra não-­‐isquémica –T0. Os fragmentos de todas as biópsias foram seccionados, para envio de amostra comparativa para processamento histológico habitual, sem qualquer alteração ao protocolo seguido habitualmente na Unidade de Transplantação do Hospital Curry Cabral. A presença de alguns parâmetros histológicos definidos, como esteatose, necrose, vacuolização, congestão sinusoidal e infiltração neutrofílica, foi registada e contabilizada numa classificação numérica. O seguimento clínico e laboratorial, bem como o acompanhamento de eventuais complicações, foi registado e correlacionado com os dados das colheitas de órgãos e com os dados das biópsias. Foram consideradas as seguintes variáveis, como as mais relevantes e objectivas para a interpretação da evolução clínica, tendo sido comparadas estatisticamente com os dados recolhidos, laboratoriais e clínicos: disfunção do enxerto, 207 pós operatórias, número de internamentos igual ou superior a 2 e rejeição crónica e/ou morte do receptor. Foram identificadas características clínicas menos favoráveis, a considerar, nalgumas circunstâncias: género feminino do receptor (sobretudo associado a enxerto masculino, p=0,077), isquémia fria superior a 500 minutos (p=0,074), isquémia quente superior a 90 minutos (p=0,099). Na análise laboratorial, distinguiram-­‐se duas características histológicas desfavoráveis e irreversíveis, como índice de mau prognóstico: a necrose e a balonização (p=0,029); no painel genético escolhido neste estudo,a expressão basal de IL-­‐1β(p=0,028), de SELE p=0,013)e de FAS-­‐L (p=0,079)relacionaram-­‐se com pior prognóstico. Algumas características protectoras intrínsecas dos enxertos só se revelaram indirectamente, como menor infiltração neutrofílica e maior expressão de HO1 e de iNOS nos enxertos PAF, não tendo sido possível provar uma interferência directa nos resultados clínicos. Não se obteve expressão mensurável de genes anti-­‐ inflamatórios nas biopsias hepáticas processadas neste estudo, como a IL13 e a I 4: assim, com a metodologia utilizada, não foi possível obter um perfil de expressão genética associado a boa evolução clínica. O perfil inverso foi sugerido apenas pela expressão basal dos 3 genes mencionados (FAS-­‐L,IL-­‐1β e SELE)no mesmo painel, com o protocolo seguido neste conjunto de 54 doentes. As características do receptor sobrepuseram-­‐se às do enxerto no caso de: -­‐ diagnóstico de PAF no receptor, que determinou uma maior predisposição para a disfunção do enxerto, o que, por sua vez, determina uma menor sobrevida. No entanto, o diagnóstico de PAF no receptor exibe uma curva de sobrevida mais favorável. -­‐ receptores com um baixo balanço de risco (BAR)definiram características favoráveis para enxertos com níveis baixos e moderados de esteatose, fazendo que esta característica, definida como um risco acrescido, não só não se manifestasse clinicamente,como parecesse um factor favorável. As características do enxerto sobrepuseram-­‐se às do receptor no caso de: -­‐ tempo de isquémia fria superior a 500 minutos -­‐ balonização, necrose, FAS-­‐L,IL-­‐1β e SELE em T0 A integração dos resultados moleculares e morfológicos com a evolução clínica, realça o papel da mobilização precoce de neutrófilos nos desempenhos menos favoráveis do enxerto hepático. -------------ABSTRACT: Orthotopic liver transplantation is na accepted therapeutic procedure for selected cases of terminal liver failure. The procedure has been improved, evidenced by the rise of survival rates from 30 to 70% at 5 years, but 13 to 27% of the liver grafts develops primary non function (PNF) or primary dysfunction (PDF) after transplantation. The consequences are devastating for the survival of the patient and of the graft. Its etiology is multifactorial, including factos related with the donor and with the recipient, ischemic times, surgical aggressions, as well as the histological characteristics of the graft. The ischemia/reperfusion lesion is still an intraoperative risk factor, with direct implications in the whole transplant outcome: there is a close interrelation between PNF and DF, graft preservation, ischemia / reperfusion lesion and graft failure. Beyond his, there is proved evidence that suggests that I/R lesion turns the allograft more vulnerable by increasing its immunogenity, increasing the probability of precocious and late rejection episodes. Based on the daily clinical practice at CHBPT /HCC, 54 cases of hepatic transplantation have been studied, grouped by allocation of each graft: Group (n=27):deceased do nortocirrhotic recipient, Group 2 (n=15): deceased donor to FAP recipient, Group 3 (n=12): FAP living donor to cirrhotic recipient. The histologic and molecular changes in the liver graft were observed until the end of the recipiente operation,together with its clinical consequences, evaluating:-­‐The different capacity of resistance of each graft to the ischemia / reperfusion lesion -­‐ The situations where the recipiente factos overlap the ones of the graft, in the definition of prognosis, and vice versa.-­‐ The relevance of the precocious histologic and molecular lesions of the hepatic tissue in the clinical outcome of the graft and the recipient. Needle biopsies were obtained from 54 liver grafts, 42 deceased brain dead donors and 12 from FAP living donors, at three diferente times of the harvesting and the hepatic transplantation: The first one (T0) before clamping the donor aorta -­‐ The second one (T2) in the end of cold ischemia time -­‐ The third one (T) after the reperfusion of the graft, during the closure of the abdominal wall. Total RNAwas extracted to these samples, converted to cDNA by reverse transcription and the analysis of gene expression was made for CTLA4,IL-­‐1β,IL-­‐4,IL-­‐6,IL-­‐13,TNF-­‐α,Perforin,E Selectin (SELE),Fas-­‐ligand,Granzyme-­‐B,Heme-­‐oxigenase 1 (HO1) and Nitric Oxide Sintetase (iNOS2A) by quantitative PCR, according with the Ct comparative method, using the expression of the non ischemic sample – T0. The fragments of all the biopsies were divided, to send a comparative sample to the usual histologic processement, keeping the same usual protocol at the Transplantation Unit of Curry Cabral Hospital. The presence of some defined histologic parameters, such as steatosis, necrosis, vacuolization, sinusoidal congestion and neutrophilic infiltration, was registered and catalogued in a numeric classification. The clinical and laboratory follow-­‐up, as well as the following of eventual complications, was registered and correlated with the data from organ procurement operations and with the data from the biopsies. The following variables were considered as the most relevant and objective ones, to the interpretation of the clinical evolution, being statistically compared with the clinical and laboratorial collected data: graft dysfunction, post-­‐operative complications, number of readmissions of 2 or more and chronic rejection and /or recipiente death. There were identified some unfavorable clinical characteristics, to be considered under certain circumstances: recipiente female gender (specially associated with malegraft, p=0,077), cold ischemia time of more than 500 minutes (p=0,074), warm ischemia time of more than 90 minutes (p=0,099). In the laboratory analysis, two histologic characteristics were identified as unfavorable and irreversible, associated with bad prognosis: necrosis and balonization (p=0,029); in the gene panel selected in this study, the basal expression of IL-­‐1β (p=0,028), SELE (p=0,013) and FAS-­‐L (p=0,079)were related with worse prognosis.Some intrinsic protective characteristics of the grafts were only indirectly revealed, such as less neutrophilic infiltration and bigger expression of HO1 and iNOS in FAP grafts, being impossible to prove any direct inte ference in the clinical results. A relevant and measurable expression of the anti inflammatory genes IL13 and IL4 was not obtained: with the used methodology, it was impossible to obtain a gene expression profile associated with a favorable clinical outcome.The inverse profile was suggested only by the basal expression of the three mentioned genes (FAS-­‐L, IL-­‐ 1β e SELE) in the same gene panel, according with the followed protocol in this group of 54 patients. The characteristics of the recipient overlapped those from the graft, in the case of :-­‐ FAP diagnosis in the recipient, which determined a bigger predisposition to graft dysfunction, which by itself determines a shorter survival. However, FAP diagnosis in the recipiente depicts a more favorable survival curve. -­‐ Recipients with a low balance risk índex (BAR) defined favorable characteristics to grafts with low and moderate grades of steatosis, making that this characteristic, associated with bad prognosis, looked like a favorable factor, and with no clinical interference. The graft characteristics overlapped those from the receptor in the case of: -­‐ Cold ischemic time more than 500 minutes -­‐ Balonization, necrosis, FAS-­‐L, IL-­‐1β and SELE at T0. The integration of molecular and morphologic results with the clinical evolution, stresses the role of a precocious neutrophils mobilization in the worse outcomes of liver grafts.

Patients with a solid organ transplant have increased in numbers and in individual survival in Switzerland over the last decades. As a consequence of long-term immunosuppression, skin cancer in solid organ recipients (SOTRs) has been recognized as an important problem. Screening and education of potential SOTRs about prevention of sun damage and early recognition of skin cancer are important before transplantation. Once transplanted, SOTRs should be seen by a dermatologist yearly for repeat education as well as early diagnosis, prevention and treatment of skin cancer. Squamous cell carcinoma of the skin (SCC) is the most frequent cancer in the setting of long-term immunosuppression. Sun protection by behaviour, clothing and daily sun screen application is the most effective prevention. Cumulative sun damage results in field cancerisation with numerous in-situ SCC such as actinic keratosis and Bowen's disease which should be treated proactively. Invasive SCC is cured by complete surgical excision. Early removal is the best precaution against potential metastases of SCC. Reduction of immunosuppression and switch to mTOR inhibitors and potentially, mycophenolate, may reduce the incidence of further SCC. Chemoprevention with the retinoid acitretin reduces the recurrence rate of SCC. The dermatological follow-up of SOTRs should be integrated into the comprehensive post-transplant care.

Purpose: Sirolimus (SRL) has been used to replace calcineurin inhibitors (CNI) for various indications including CNI-induced toxicity. The aim of this study was to evaluate the efficacy and safety of switching from CNI to SRL in stable renal transplant recipients (RTR) with low grade proteinuria (<1 g/24 h). Methods and materials: Between 2001 and 2007, 41 patients (20 females, 21 males; mean age 47 ± 13) were switched after a median time post-transplantation of 73.5 months (range 0.2-273.2 months). Indications for switch were CNI nephrotoxicity (39%), thrombotic micro-angiopathy (14.6%), post-transplantation cancer (24.4%), CNI neurotoxicity (7.4%), or others (14.6%). Mean follow-up after SRL switch was 23.8±16.3 months. Mean SRL dosage and through levels were 2.4 ± 1.1 mg/day and 8 ± 2.2 ug/l respectively. Immunosuppressive regiments were SRL + mycophenolate mofetil (MMF) (31.7%), SRL + MMF + prednisone (36.58%), SRL + prednisone (19.51%), SRL + Azathioprine (9.75%), or SRL alone (2.43%). Results: Mean creatinine decreased from 164 to 143 μmol/l (p <0.03), mean estimated glomerular filtration rate (eGFR) increased significantly from 50.13 to 55.01 ml/minute (p <0.00001), mean systolic and diastolic blood pressure decreased from 138 to 132 mm Hg (p <0.03) and from 83 to78 mm Hg (p <0.01), but mean proteinuria increased from 0.21 to 0.63 g/24 h (p <0.001). While mean total cholesterolemia didn't increased significantly from 5.09 to 5.56 mmol/l (p = 0.06). The main complications after SRL switch were dermatitis (19.5%), urinary tract infections (24.4%), ankle edema (13.3%), and transient oral ulcers (20%). Acute rejection after the switch occurred in 7.3% of patients (n = 3), and 2 acute rejections were successfully treated with corticosteroids and 1 did not respond to treatment (not related to switch). SRL had to be discontinued in 17% of patients (2 nephrotic syndromes, 2 severe edema, 1 acute rejection, 1 thrombotic micro-angiopathy, and 1 fever). Conclusion: In conclusion, we found that switching from CNI to SRL in stable RTR was safe and associated with a significant improvement of renal function and blood pressure. Known side-effects of SRL led to drug discontinuation in less than 20% of patients and the acute rejection rate was 7.3%. This experience underlines the importance of patient selection before switching to SRL, in particular regarding preswitch proteinuria.

The mechanisms by which CD4(+)CD25(+)Foxp3(+) T (Treg) cells regulate effector T cells in a transplantation setting and their in vivo homeostasis still remain to be clarified. Using a mouse adoptive transfer model, we analyzed the in vivo expansion, trafficking, and effector function of alloreactive T cells and donor-specific Treg cells, in response to a full-thickness skin allograft. Fluorescent-labeled CD4(+)CD25(-) and antigen-specific Treg cells were transferred alone or co-injected into syngeneic BALB/c-Nude recipients transplanted with skins from (C57BL/6 x BALB/c) F1 donors. Treg cells divided in vivo, migrated and accumulated in the allograft draining lymph nodes as well as within the graft. The co-transfer of Treg cells did not modify the early activation and homing of CD4(+)CD25(-) T cells in secondary lymphoid organs. However, in the presence of Treg cells, alloreactive CD4(+)CD25(-) T cells produced significantly less IFN-gamma and were present in reduced numbers in the secondary lymphoid organs. Furthermore, time-course studies showed that Treg cells were recruited into the allograft at a very early stage after transplantation and effectively prevented the infiltration of effector T cells. In conclusion, suppression of rejection requires the early recruitment to the site of antigenic challenge of donor-specific Treg cells, which then mainly regulate the effector arm of T cell alloresponses.

Antiretroviral-therapy has dramatically changed the course of HIV infection and HIV-infected (HIV(+)) individuals are becoming more frequently eligible for solid-organ transplantation. However, only scarce data are available on how immunosuppressive (IS) strategies relate to transplantation outcome and immune function. We determined the impact of transplantation and immune-depleting treatment on CD4+ T-cell counts, HIV-, EBV-, and Cytomegalovirus (CMV)-viral loads and virus-specific T-cell immunity in a 1-year prospective cohort of 27 HIV(+) kidney transplant recipients. While the results show an increasing breadth and magnitude of the herpesvirus-specific cytotoxic T-cell (CTL) response over-time, they also revealed a significant depletion of polyfunctional virus-specific CTL in individuals receiving thymoglobulin as a lymphocyte-depleting treatment. The disappearance of polyfunctional CTL was accompanied by virologic EBV-reactivation events, directly linking the absence of specific polyfunctional CTL to viral reactivation. The data provide first insights into the immune-reserve in HIV+ infected transplant recipients and highlight new immunological effects of thymoglobulin treatment. Long-term studies will be needed to assess the clinical risk associated with thymoglobulin treatment, in particular with regards to EBV-associated lymphoproliferative diseases.

In this review, we discuss a paradigm whereby changes in the intragraft microenvironment promote or sustain the development of chronic allograft rejection. A key feature of this model involves the microvasculature including (a) endothelial cell (EC) destruction, and (b) EC proliferation, both of which result from alloimmune leukocyte- and/or alloantibody-induced responses. These changes in the microvasculature likely create abnormal blood flow patterns and thus promote local tissue hypoxia. Another feature of the chronic rejection microenvironment involves the overexpression of vascular endothelial growth factor (VEGF). VEGF stimulates EC activation and proliferation and it has potential to sustain inflammation via direct interactions with leukocytes. In this manner, VEGF may promote ongoing tissue injury. Finally, we review how these events can be targeted therapeutically using mTOR inhibitors. EC activation and proliferation as well as VEGF-VEGFR interactions require PI-3K/Akt/mTOR intracellular signaling. Thus, agents that inhibit this signaling pathway within the graft may also target the progression of chronic rejection and thus promote long-term graft survival.

QUESTIONS UNDER STUDY: The field of heart transplantation has seen substantial progress in the last 40 years. The breakthroughs in long-term survival were followed by a period of stagnation in the last decade. This review summarises current recommendations for the identification of candidates for heart transplantation and their immunological and non-immunological postoperative follow-up. RESULTS: The progress made in the treatment of patients with advanced heart failure has considerably changed the profile of candidates for heart transplantation. Patients are older, and the load of co-morbidities is more important requiring careful evaluation for candidacy. Long-standing research in the field of immunosuppression made available various drugs, which decrease the risk of acute allograft rejection and prolong survival after heart transplantation. Powerful new molecules are entering early phase clinical studies, suggesting further improvement in the near future. As a consequence, treatment of non-immunological co-morbidity after heart transplantation will gain in importance, however, the base of evidence guiding current recommendations is poor. CONCLUSIONS: The substantial progress in heart failure treatment and immunosuppression after heart transplantation has changed the profile of heart transplant recipients. The arrival of new molecules will provide additional alternatives for immunosuppressive treatment while studies have to address non-immunological treatment in order to improve long-term survival after heart transplantation.

To the best of our knowledge, this is the first report of an undifferentiated pleomorphic sarcoma arising from a renal graft. Transplantectomy was performed in a 47-year old woman presenting to the emergency room because of general weakness. Preoperative workup revealed a 5.5 cm malignant mass of the graft which was not present on routine ultrasound performed 12 months earlier. Following transplantectomy, local recurrence developed despite complete tumor resection and interruption of immunosuppression. Despite radiation therapy, the outcome was ultimately fatal. Genetic analysis revealed that the tumor had arisen from donor tissue. Annual ultrasound surveillance might not be enough effective to screen for these rare high grade neoplasms.

Abstract This research takes the lens of social reproduction as a starting point for an examination of the effects of recent social welfare reforms on the lives o.fsingle mothers. As the cumulative effects o.f diminishing state provided benefits take hold, tensions are heightened as single mothers internalize the insecurity of earning an income in 11 capitalist labour market, while trying to carry out all that is involved in social reproduction with inadequate means of survival. Through interviewing single mothers who are the recipients of mUltiple state provided benefits (social assistance, student loans, subsidized housing and subsidized childcare), this thesis illuminates the cOl1linued regulation of women in an effort to assure that social reproduction is occurring at the lowest cost possible. State provided benefits are set lip in such a way that it is near impossible for single mothers to make ends meet without entering the labour force or entering into co-residential relationships. This push towards the labour force and/or marriage via punitive welfare policies illuminates the devaluation of the labour that is done at home. Through interviewing 5 single mothers, I will demonstrate the extensive labour that goes into maintaining their households. In addition .J case managers are interviewed. The employees of social assistance, subsidized hOllsing, subsidized childcare and student loans, have much agency in deeming who is worthy of receiving benefits. The employees of these agencies have the ability to make these women's lives easier or more complicated by how the workers interpret the policy regulations. Social policies are of paramount importance in the quest for women's equality and thus have consequences for how women's daily lives are organized. The rules and regulations that govern the individual policies are complex and bureaucratic and have implications for the ways in which women must organize their lives in order to survive. The shifts in social policy have been guided by neo-liberal assumptions with a focus on individual responsibility and a market-modeled welfare state. The caring work that is involved in raising children to be productive in a capitalist society is ignored or devalued in current policies. The emphasis in each polic.:v is on getting women who receive benefits into the paid work force, with little facilitation or investment into the caring work these women do on a daily basis that in turn supports capitalism. Policies, such as social assistance, subsidized housing, subsidized childcare and student loans, are set up in such a way that ignores the reality of women's day-to-day lives and devalues the necessary work done at home. It takes an abundance of labour and strategizing for women to seek out necessary means of survival, labour that is amplified when a woman is dealing with mUltiple slate provided benefits.
