Abstract
Immunosuppressed individuals face a significantly elevated risk of developing aggressive cutaneous malignancies, often surpassing the aggressiveness observed in immunocompetent counterparts. Our patient exhibited several risk factors associated with melanoma development in renal recipients, including skin type, sun exposure, and the duration of immunosuppression. The determination of staging holds paramount importance as it directly influences both prognosis and subsequent management. It is crucial to handle suspected lesions with caution in these patients to facilitate early melanoma detection and enhance overall prognosis.

Abstract
Introduction Mucocutaneous complications in kidney transplant patients are due to drug toxicity or immunosuppression. The main objective of our study was to determine the risk factors associated with their occurrence. Methods We conducted a prospective analytical study (January 2020- June 2021) including kidney transplant patients seen at the Nephrology Department. We described the characteristics of the patients who presented mucocutaneous complications and then compared them to those who didn't to deduce the risk factors. Statistical analysis was performed using SPSS 20.0 (p<0.05). Results Of the 86 patients recruited, thirty patients had mucocutaneous complications. The mean age was 42.73, with a male predominance (73%). Ten kidney transplants were performed from a living-related donor. All the patients received corticosteroids, Mycophenolate Mofetil, and the Calcineurin Inhibitor: Tacrolimus (76.7%) or Ciclosporin (23.3%). Induction was performed with Thymoglobulin (n=20) or Basiliximab (n=10). Mucocutaneous complications were dominated by infectious manifestations (53.4%): eight cases of fungal infections; six cases of viral infections: warts (n=3), herpes labialis (n=2), intercostal herpes zoster (n=1), and two cases of bacterial infections: atypical mycobacteria and boils. Inflammatory complications (36.6%) included acne (n=4), urticaria (n=3), rosacea (n=1), simple maculopapular exanthema (n=1), aphthous lesion (n=1), and black hairy tongue (n=1). Actinic keratosis, skin xerosis, and bruises were found in one patient respectively. The evolution with a symptomatic treatment was good in all the patients. After statistical analysis, the factors significantly associated with the occurrence of mucocutaneous complications were advanced age, male gender, anemia, HLA non-identical donor, as well as the use of Tacrolimus or Thymoglobulin. Conclusion Infectious mucocutaneous complications are the most common dermatological manifestations among renal transplant recipients. Their occurrence is related to advanced age, male gender, anemia, HLA non-identical donor, and the use of Tacrolimus or Thymoglobulin.

Abstract
BACKGROUND AND OBJECTIVES Although most cutaneous squamous cell carcinoma (cSCC) cases are generally nonlethal and manageable with surgical excision, there ares till significant hazards for patients who are ineligible for surgical resection. We sought to find a suitable and effective treatment for cSCC. METHODS We modified chlorin e6 by adding a hydrogen chain with a six-carbon ring to the benzene ring and named this new photosensitizer as STBF. We first investigated the fluorescence characteristics, cellular uptake of STBF and subcellular localization. Next, cell viability was detected by CCK-8 assay and the TUNEL staining was performed. Akt/mTOR-related proteins were examined by western blot. RESULTS STBF-photodynamic therapy (PDT) inhibits cSCC cells viability in a light dose dependent manner. The antitumor mechanism of STBF-PDT might be due to the suppression of the Akt/mTOR signaling pathway. Further animal investigation determined that STBF-PDT led to a marked reduction in tumor growth. CONCLUSIONS Our results suggest that STBF-PDT exerts significant therapeutic effects in cSCC. Thus, STBF-PDT is expected to be a promising method for the treatment of cSCC and the photosensitizer STBF may be destined for a wider range of applications in photodynamic therapy.

Abstract
Actinic keratoses and cutaneous squamous cell carcinomas are associated with infections with human papillomavirus of genus beta (betaHPV) in immunosuppressed patients. To date, targeted therapy against betaHPV-associated skin cancer does not exist because of the large number of betaHPV without defined high-risk types. In this study, we hypothesized that the activation of innate antiviral immunity in the skin, asymptomatically infected with betaHPV, induces an antitumor response by in situ autovaccination and prevents the formation of betaHPV-associated skin cancer. To test this, we used the preclinical keratin-14-HPV8 transgenic mouse model, which develops skin tumors after mechanical wounding. Remarkably, treatment with the antiviral immune response activating polyinosinic-polycytidylic acid (poly[I:C]) completely prevented cutaneous tumor growth. The induction of the IFN-induced genes Cxcl10 and Ifit1 by poly(I:C) depended on MDA5 activation. Increased numbers of total and activated CD4 and CD8 T cells were detected in poly(I:C)-treated skin. T cells were found in the skin of poly(I:C)-treated mice but not in the skin tumors of untreated mice. T-cell depletion showed a predominant role of CD4 T cells in poly(I:C)-mediated tumor prevention. Our findings identify the MDA5 ligand poly(I:C) as a promising candidate for in situ autovaccination approaches, which might serve as a treatment strategy against betaHPV-related skin diseases.

Abstract
As the risk of graft loss due to acute rejection has declined, the goal of post-transplant management has switched to long-term preservation of organ function. Minimizing calcineurin inhibitor (CNI)-related nephrotoxicity is a key component of this objective. Everolimus is a mammalian target of rapamycin inhibitor/proliferation-signal inhibitor with potent immunosuppressive and anti-proliferative effects. It has been widely investigated in large randomized clinical studies that have shown it to have similar anti-rejection efficacy compared with standard-of-care regimens across organ transplant indications. With demonstrated potential to facilitate the reduction of CNI therapy and preserve renal function, everolimus is an alternative to the current standard-of-care CNI-based regimens used in de novo and maintenance solid organ transplantation recipients. Here, we provide an overview of the evidence from the everolimus clinical study program across kidney, liver, heart, and lung transplants, as well as other key data associated with its use in CNI reduction strategies in adult transplant recipients.

Abstract
Nearly two million cases of cutaneous squamous cell carcinoma (cSCC) are diagnosed every year in the United States alone. cSCC is notable for both its prevalence and its propensity for invasion and metastasis. For many patients, surgery is curative. However, patients experiencing immunosuppression or recurrent, advanced, and metastatic disease still face limited therapeutic options and significant mortality. cSCC forms after decades of sun exposure and possesses the highest known mutation rate of all cancers. This mutational burden complicates efforts to identify the primary factors driving cSCC initiation and progression, which in turn hinders the development of targeted therapeutics. In this review, we summarize the mutations and alterations that have been observed in patients’ cSCC tumors, affecting signaling pathways, transcriptional regulators, and the microenvironment. We also highlight novel therapeutic opportunities in development and clinical trials.

Abstract
BACKGROUND Cutaneous squamous cell carcinoma (SCC) is the second most common type of skin cancer. Only 2% to 5% of SCCs metastasize; however, those do carry a poor prognosis. Immunohistochemistry (IHC) is widely used by pathologists to characterize skin cancers and provide clinically useful information. OBJECTIVE To evaluate the potential prognostic associations between IHC findings and metastasis in SCC. METHODS Searches were conducted in MEDLINE via PubMed for articles published between 1999 and 2019. Search criteria included key words "immunohistochemistry" and "cutaneous squamous cell carcinoma." Six hundred and fifty-three articles were returned and screened, which ultimately left 31 for inclusion in our manuscript. RESULTS Thirty-one articles analyzed in this review included a discussion of the expression of a particular IHC marker and the associated risk of metastasis and/or clinical utility of IHC markers in SCC, especially metastatic SCC. Markers that had several or more studies supporting clinical utility were E-cadherin, podoplanin, CD8+ T cells, PD-L1, epidermal growth factor receptor, and Cyclin D1. CONCLUSION Immunohistochemistry profiling of SCC may be useful in select cases when providing a prognosis remains challenging and in identification of potential therapeutic targets for high-risk or metastatic tumors.

Abstract
Background Solid organ transplantation is associated with increased risk of non-melanoma skin cancer. Studies with short follow up times have suggested a reduced occurrence of these cancers in recipients treated with mammalian target of rapamycin inhibitors as maintenance immunosuppression. We aimed to describe the occurrence of skin cancers in renal and liver transplant recipients switched from calcineurin inhibitor to sirolimus-based regimes. Methods We performed a retrospective study of sirolimus conversion within the Irish national kidney and liver transplant programs. These data were linked with the National Cancer Registry Ireland to determine the incidence of NMSC among these recipients. The incidence rate ratio (IRR) for post versus pre-conversion NMSC rates are referred in this study as an effect size with [95% confidence interval]. Results Of 4,536 kidney transplants and 574 liver transplants functioning on the 1 January 1994 or transplanted between 1 January 1994 and 01 January 1994 and 01 January 2015, 85 kidney and 88 liver transplant recipients were transitioned to sirolimus-based immunosuppression. In renal transplants, the rate of NMSC was 131 per 1000 patient years pre-switch to sirolimus, and 68 per 1000 patient years post switch, with adjusted effect size of 0.48 [0.31 − 0.74] (p = .001) following the switch. For liver transplant recipients, the rate of NMSC was 64 per 1,000 patient years pre-switch and 30 per 1,000 patient years post switch, with an adjusted effect size of 0.49 [0.22 − 1.09] (p .081). Kidney transplant recipients were followed up for a median 3.4 years. Liver transplants were followed for a median 6.6 years. Conclusions In this study, the conversion of maintenance immunosuppression from calcineurin inhibitors to mTOR inhibitors for clinical indications did appear to reduce the incidence of NMSC in kidney and liver transplant recipients.

IFN-γ Critically Enables the Intratumoural Infiltration of CXCR3 + CD8 + T Cells to Drive Squamous Cell Carcinoma Regression. Cancers (Basel) 2021; 13:cancers13092131.

Abstract
Simple Summary Cutaneous squamous cell carcinoma (SCC) is prevalent in aged individuals and individuals with compromised or weakened immune systems, indicating a close association between immune function and SCC control. The aim of our study was to uncover the identity of key immune subsets that mediate SCC control, and to elucidate the mechanistic role of the proinflammatory cytokine Interferon-gamma in this process. We established a SCC regressor model, which we used to determine that: (1) CD8+ T cells, not CD4+ T cells or NK cells, are essential for SCC regression; (2) the neutralisation of Interferon-gamma prevents CD8+ T cell infiltration and SCC regression; (3) CD8+ T cell migration into SCC critically depends upon Interferon-gamma-induced chemokine expression. Thus, our model can be used to understand the key immune mechanisms involved in SCC regression, which will support targeted investigations into the integrity of these mechanisms in patients with progressive disease. Abstract Ultraviolet (UV) radiation-induced tumours carry a high mutational load, are highly immunogenic, and often fail to grow when transplanted into normal, syngeneic mice. The aim of this study was to investigate factors critical for the immune-mediated rejection of cutaneous squamous cell carcinoma (SCC). In our rejection model, transplanted SCC establish and grow in mice immunosuppressed with tacrolimus. When tacrolimus is withdrawn, established SCC tumours subsequently undergo immune-mediated tumour rejection. Through the depletion of individual immune subsets at the time of tacrolimus withdrawal, we established a critical role for CD8+ T cells, but not CD4+ T cells, γδ T cells, or NK cells, in driving the regression of SCC. Regression was critically dependent on IFN-γ, although IFN-γ was not directly cytotoxic to SCC cells. IFN-γ-neutralisation abrogated SCC regression, significantly reduced CD8+ T cell-infiltration into SCC, and significantly impaired the secretion of CXCL9, CXCL10 and CCL5 within the tumour microenvironment. A strong positive correlation was revealed between CXCL10 expression and CD8+ T cell abundance in tumours. Indeed, blockade of the CXCL10 receptor CXCR3 at the time of tacrolimus withdrawal prevented CD8+ T cell infiltration and the regression of SCC. Chimeric models revealed an important role for immune cells as producers of IFN-γ, but not as recipients of IFN-γ signals via the IFN-γ receptor. Together, these findings suggest a key role for IFN-γ in driving the expression of chemokines within the tumour environment essential for the destruction of established SCC by CD8+ T cells.

Abstract
BACKGROUND Keratinocyte carcinomas, particularly squamous cell carcinoma (SCC), occur more frequently and aggressively in solid-organ transplant recipients (SOTRs) than in the general population. Systemic retinoids are effective in secondary prevention of keratinocyte carcinomas in this population, but their use is limited by adverse effects including a rebound effect in cases of treatment discontinuation. OBJECTIVE Our aim was to determine whether low-dose acitretin is efficient in the secondary prevention of keratinocyte carcinomas in SOTRs. METHODS This retrospective case-crossover study was conducted at a specialized dermatology clinic for SOTRs in a large transplantation center in 2010-2017. Patients with at least 1 previous keratinocyte carcinoma who were treated with acitretin 10 mg/day for 2 years were included. The main outcome was the difference in the number of new keratinocyte carcinomas diagnosed during treatment compared to during the 2-year pretreatment period. RESULTS The cohort included 34 SOTRs. A significant reduction in the mean number of new keratinocyte carcinomas during treatment relative to the pretreatment period was observed (1.7 vs. 3.6, -53% p = 0.002). Similar results were noted on analysis by tumor type, for both SCC and basal cell carcinoma. CONCLUSION This study of SOTRs demonstrated positive results for low-dose acitretin as a chemoprevention of keratinocyte carcinomas in this population.

Abstract
Ultraviolet (UV) radiation is the main risk factor for the development of melanocytic and nonmelanocytic skin cancer. UVA and UVB radiation are of particular importance in photocarcinogenesis. Depending on the wavelength, mechanisms of tumor initiation and promotion include direct DNA damage and proinflammatory processes. In recent years, the number of skin cancer cases in Germany has continuously increased. In addition to regular skin check-ups, use of suitable textile protection and sunscreens play a central role in the prevention of cancer development. As dermatologists, it is our task to regularly inform our patients about the consequences of excessive sun exposure and to adequately inform them about necessary protective devices.

Abstract
In this review, we analyze the 3 clinical scenarios related to the development of melanoma in solid organ transplant recipients: melanoma in patients with a history of the tumor prior to a transplant, de novo melanoma following a transplant, and melanoma of donor origin. The main factors to consider in organ-transplant candidates with a history of melanoma are tumor stage, presence or absence of residual disease, and time from diagnosis to transplantation. Solid organ transplant recipients have a greater risk of melanoma than immunocompetent individuals. Mortality is also higher in this population, especially in patients with advanced melanoma, as treatment is especially challenging. Clinical history and physical examination provide the most useful information for preventing donor-to-recipient transmission of melanoma. Donor-derived melanoma has a very poor prognosis.

Abstract
Nicotinamide is a water-soluble vitamin B3 derivative that has many roles in medicine. This review examines the role of nicotinamide in dermatology and its actions in preventing photoageing and skin cancers in humans. Nicotinamide prevents ultraviolet radiation (UV) from reducing ATP levels and inhibiting glycolysis, thus preventing the UV radiation-induced energy crisis. This enhances DNA repair and reduces UV-induced suppression of immunity. Randomised controlled clinical trials have also shown that nicotinamide reduces transepidermal water loss and the development of new non-melanoma skin cancers in high-risk humans. This review also examines nicotinamide's safety profile.

Abstract
During the last decade, the worldwide incidence of keratinocyte carcinomas (KC) has increased significantly. They are now the most common malignancy, representing approximately 30% of all cancers. The role of ultraviolet (UV) radiation as a major environmental risk factor for skin cancers is well recognized. The aim of this review is to analyse the current understanding of the nature of beta-human papillomavirus (HPV) and its association with KC and explore the implications for the management and prevention of these cancers. A comprehensive review of the literature on beta-HPV and its association with KC was undertaken, the results reported in the form of a narrative review. A subgroup of HPV that infects the mucosal epithelia of the genital tract has been firmly associated with carcinogenesis. In addition, some HPV types with cutaneous tropism have been proposed to cooperate with UV in the development of KC. The first evidence for this association was reported in 1922 in patients with epidermodysplasia verruciformis (EV). Since then, epidemiological studies have highlighted the higher risk of skin cancer in patients with EV and certain cutaneous HPV types, and in vitro studies have elucidated molecular mechanisms and transforming properties of beta-HPV. Furthermore, in vivo research conducted on transgenic mice models has shown the possible role of beta-HPV in cutaneous carcinogenesis as a co-factor with UV radiation and immunosuppression. There is good evidence supporting the role of beta-HPV in the oncogenesis of KC. The high prevalence of beta-HPV in human skin and the worldwide burden of KC makes the search for an effective vaccine relevant and worthwhile.

Abstract
Transplant recipients have a significantly higher risk of developing non-melanoma skin cancers compared with the general population and squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) are the most common post-transplant malignancies. Although in the general population BCC outnumbers SCC 4:1, in transplant patients this ratio is reversed and SCC is more common, with a 65- to 250-fold increased incidence. As patients in immunosuppressed states are living longer after transplants, the incidence of skin cancer in this population continues to increase. The skin cancers in transplant patients also tend to be more aggressive, with higher morbidity and mortality. Preventive strategies play an important role in transplant recipients given their increased frequency of developing both premalignant and malignant skin lesions. Sun protection and regular skin cancer screening are critical. In addition, chemoprophylaxis with systemic retinoids, nicotinamide and capecitabine can significantly reduce the development of new skin cancers. Topical 5-fluorouracil, imiquimod, photodynamic therapy and cyclooxygenase inhibitors have all been investigated in transplant patients for the treatment of field cancerisation. Adjusting the immunosuppressive regimen is also an important adjuvant therapeutic strategy for managing skin cancers in transplant recipients and requires integrated multidisciplinary care with the entire transplant team. This article reviews the epidemiology of non-melanoma skin cancer in transplant patients, discusses the prevention strategies and highlights the management and treatment strategies of both field cancerisation and non-melanoma skin cancers.

Abstract
The aim of this study was to compare liver transplant recipients (LTRs) with the general population regarding their knowledge of skin cancer, sun health, sun protection behaviors, and affecting factors. This cross-sectional study was conducted in Turkey between March 2016 and September 2016 with 104 LTRs and 100 participants from the general population group (GPG). The mean age of the LTRs was 53.2 ± 11.8 and that of the GPG was 42.7 ± 14.5. The LTRs' skin cancer and sun knowledge were significantly lower than in the GPG, but there was no difference between the two groups in terms of their sun protection behavior scores. The most commonly used sun protection behaviors of LTRs were not being outside and not sunbathing between 10 a.m. and 4 p.m., wearing clothing that covers the skin, and avoiding the solarium. Behaviors commonly practiced by the GPG were wearing sunglasses, wearing sunscreen with a sun protection factor of 15 or higher before going outside, wearing sunscreen at the beach, while swimming or doing physical activity outside, and reapplying it every 2 h. Results of our study will contribute to the development of education and training programs for LTRs on skin cancer. The results also demonstrated the importance of practicing adequate sun protection behaviors which will certainly impact their future health.

Abstract
Background Previous studies show that mTOR inhibitors decrease the risk of cancer development after kidney transplantation. However, the effect of cumulative doses of mTOR inhibitors on cancer after kidney transplantation is not well known. Methods In the current study, patients were registered into a national database in Taiwan. Between year 2000 and 2013, 4,563 patients received kidney transplantation. They were divided into two groups, according to mTOR inhibitors usage. The cumulative dose of mTOR inhibitors was recorded. Patients were followed-up until de novo cancer development, death, or the end of 2014. Results Patients were divided into two groups: mTOR inhibitors users (study group, n = 828) and mTOR inhibitors non-users (control group, n = 3,735). The median follow-up duration was 7.8 years. The risk of de novo cancer (hazards ratio (HR) 0.80, 95% CI [0.60–1.09], p = 0.16) and risk of death (HR 1.14, 95% CI [0.82–1.60], p = 0.43) was not different between mTOR inhibitor user and non-user groups. Neither high- nor low-dose exposure to mTOR inhibitors was associated with increased risk of cancer or mortality. Analysis of cancer subtypes showed no influence by mTOR inhibitors. In addition, the cause of mortality was not significantly different between the two groups. Discussion We could not find the association of mTOR inhibitors use and risk of de novo cancer development or mortality in patients with kidney transplantation in Chinese patients. Cumulative exposure to mTOR inhibitors did not change the results.

Abstract
There is still controversy in the scientific field about whether certain types of cutaneous human papillomaviruses (HPVs) are causally involved in the development of non-melanoma skin cancer (NMSC). Deciphering the etiological role of cutaneous HPVs requires - besides tissue culture systems - appropriate preclinical models to match the obtained results with clinical data from affected patients. Clear scientific evidence about the etiology and underlying mechanisms involved in NMSC development is fundamental to provide reasonable arguments for public health institutions to classify at least certain cutaneous HPVs as group 1 carcinogens. This in turn would have implications on fundraising institutions and health care decision makers to force - similarly as for anogenital cancer - the implementation of a broad vaccination program against "high-risk" cutaneous HPVs to prevent NMSC as the most frequent cancer worldwide. Precise knowledge of the multi-step progression from normal cells to cancer is a prerequisite to understand the functional and clinical impact of cofactors that affect the individual outcome and the personalized treatment of a disease. This overview summarizes not only recent arguments that favor the acceptance of a viral etiology in NMSC development but also reflects aspects of causality in medicine, the use of empirically meaningful model systems and strategies for prevention.

Abstract
Neoplastic skin lesions are multifocal, diffuse skin infiltrations of particular relevance in the differential diagnosis of ulcerative, nodular, or crusting skin lesions. Nonmelanoma skin cancers (NMSCs), namely, basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and also actinic keratosis (AK), are the most common malignant tumors in humans. BCCs do not proliferate rapidly and most of the times do not metastasize, while SCCs are more infiltrative, metastatic, and destructive. AKs are precursor lesions of cutaneous SCCs. The classical therapy of NMSCs makes use of photodynamic therapy associated with chemotherapeutics. With improved understanding of the pathological mechanisms of tumor initiation, progression, and differentiation, a case is made towards the use of targeted chemotherapy with the intent to reduce the cytotoxicity of classical treatments. The present review aims to describe the current state of the art on the knowledge of NMSC, including its risks factors, oncogenes, and skin carcinogenesis, discussing the classical therapy against new therapeutic options.

Abstract
Although tremendous progress has been made in recent years in skin cancer care for organ transplant recipients, significant gaps remain in data-driven clinical guidelines, particularly for the treatment and prevention of cutaneous squamous cell carcinoma (cSCC), the most common malignancy among this population. In this review, we aim to summarize current knowledge around the management of cSCC and highlight the most significant gaps in knowledge that continue to pose challenges in the delivery of skin cancer care for organ transplant recipients. We suggest future directions for research that will bridge existing gaps and establish evidence-driven guidelines for primary prevention, screening and treatment of cSCC in this high-risk patient population.

Abstract
Cutaneous squamous cell carcinoma (cSCC) derives from keratinocytes in the epidermis and accounts for 15–20% of all cutaneous malignancies. Although it is usually curable by surgery, 5% of these tumours metastasise leading to poor prognosis mostly because of a lack of therapies and validated biomarkers. As the incidence rate is rising worldwide it has become increasingly important to better understand the mechanisms involved in cSCC development and progression in order to develop therapeutic strategies. Here we discuss some of the evidence indicating that activation of phosphoinositide 3-kinases (PI3Ks)-dependent signalling pathways (in particular the PI3Ks targets Akt and mTOR) has a key role in cSCC. We further discuss available data suggesting that inhibition of these pathways can be beneficial to counteract the disease. With the growing number of different inhibitors currently available, it would be important to further investigate the specific contribution of distinct components of the PI3Ks/Akt/mTOR pathways in order to identify the most promising molecular targets and the best strategy to inhibit cSCC.

Abstract
Background Epidermolysis bullosa is a group of diseases caused by mutations in genes for proteins responsible for cells’ anchorage at the dermo-epidermal junction. Their common feature are dysfunctional or even absent connections between cells. The typical clinical sign is the formation of blisters, with possible excessive scarring, in response to minimal skin irritation. End stage renal disease may be one of the comorbidities in patients with epidermolysis bullosa. The implementation of renal replacement therapy may be very difficult in this population. This is mainly due to problems in obtaining the proper dialysis access. The choice of appropriate method may be crucial for patient’s survival. Case presentation We present a case of 29-year-old woman with Epidermolysis bullosa caused by laminin 5 gene mutation. The patient suffered from additional conditions: blindness, complete bilateral sensorineural deafness and oesophageal stenosis. When end stage renal disease was diagnosed, the problem of renal replacement therapy had to be faced. There have been few reports concerning ESRD in this specific group of patients in the available literature. In most of them the prognosis was very poor. Nevertheless, we were very determined to overcome all the difficulties. Special procedures and cooperation with the patient’s family allowed us to consider kidney transplantation as a treatment option. Conclusion There should be no limitations in renal replacement therapy in patients with epidermolysis bullosa. Haemodialysis, peritoneal dialysis and kidney transplantation are all possible treatment options. Nevertheless, either method requires special procedures.

Abstract
BACKGROUND Lymphocyte subsets play important roles in rejection in liver transplant recipients, and the effect of splenic function on these roles remains unknown. The aim of this study was to explore the feasibility to adjust immunosuppressive agents based on splenic function status through detecting the lymphocyte subsets in liver transplantBeijing recipients. METHODS The lymphocyte subsets of 49 liver transplant recipients were assessed in the 309th Hospital of Chinese People's Liberation Army between June 2014 and August 2015. The patients were divided into splenectomy group (n = 9), normal splenic function group (n = 24), and hypersplenism group (n = 16). The percentages and counts of CD4+ T, CD8+ T, natural killer (NK) cell, B-cell, regulatory B-cell (Breg), and regulatory T-cell (Treg) were detected by flow cytometer. In addition, the immunosuppressive agents, histories of rejection and infection, and postoperative time of the patients were compared among the three groups. RESULTS There was no significant difference of clinical characteristics among the three groups. The percentage of CD19+CD24+CD38+ Breg was significantly higher in hypersplenism group than normal splenic function group and splenectomy group (3.29 ± 0.97% vs. 2.12 ± 1.08% and 1.90 ± 0.99%, P = 0.001). The same result was found in CD4+CD25+FoxP3+ Treg percentage (0.97 ± 0.39% vs. 0.54 ± 0.31% and 0.56 ± 0.28%, P = 0.001). The counts of CD8+ T-cell, CD4+ T-cell, and NK cell were significantly lower in hypersplenism group than normal splenic function group (254.25 ± 149.08 vs. 476.96 ± 225.52, P= 0.002; 301.69 ± 154.39 vs. 532.50 ± 194.42, P= 0.000; and 88.56 ± 63.15 vs. 188.33 ± 134.51, P = 0.048). Moreover, the counts of CD4+ T-cell and NK cell were significantly lower in hypersplenism group than splenectomy group (301.69 ± 154.39 vs. 491.89 ± 132.31, P= 0.033; and 88.56 ± 63.15 vs. 226.00 ± 168.85, P = 0.032). CONCLUSION Splenic function status might affect the immunity of liver transplant recipients, that should be considered when we make immunosuppressive protocols.

Abstract
The ketogenic diet has been shown to be beneficial for numerous diseases across different organ systems, but a dearth of information exists regarding these benefits for skin disease. Here, we searched the literature for known mechanisms behind inflammation in dermatologic disease and correlated that with suggested mechanisms of anti-inflammatory activity of ketones and a ketogenic state in the human body to observe how ketones and ketosis might aid in the treatment of inflammatory skin diseases based on these mechanisms. Specifically, we found that ketones modulate the NRPL3 inflammasome, augment anti-oxidation against reactive oxygen species through various direct and indirect means, and may influence mTOR activity, which are all involved in inflammatory dermatologic diseases to an extent. This evidence shows that ketones and the ketogenic diet may have a promising role in the dermatologist's disease treatment repertoire. Our goal is to provide a novel direction for research in the role of a ketogenic diet and even exogenous ketone therapy in the treatment of inflammatory dermatologic disease.

Abstract
Cigarette smoking affects many organs. It causes vasoconstriction through activation of sympathetic nervous system which leads to elevation of blood pressure and reduction in glomerular filtration rate and filtration pressure. It also causes thickening of renal arterioles. Cigarette smoking increases the risk of microalbuminuria and accelerates progression of microalbuminuria to macroalbuminuria. Furthermore, it causes rapid loss of glomerular filtration rate in chronic kidney disease patients. After kidney donation, these factors may be injurious to the solitary kidney. Kidney donors with history of cigarette smoking are prone to develop perioperative complications, pneumonia, and wound infection. Postkidney transplantation various stressors including warm and cold ischemia time, delayed graft function, and exposure to calcineurin inhibitors may result in poor graft function. Continuation of cigarette smoking in kidney transplant recipients will add further risk. In this review, we will specifically discuss the effects of cigarette smoking on normal kidneys, live kidney donors, and kidney transplant recipients. This will include adverse effects of cigarette smoking on graft and patient survival, cardiovascular events, rejection, infections, and cancers in kidney transplant recipients. Lastly, the impact of kidney transplantation on behavior and smoking cessation will also be discussed.

Abstract
Cancer stem cells (CSCs) are found in many cancer types, including squamous cell carcinoma (SCC). CSCs initiate cancer formation and are linked to metastasis and resistance to therapies. Studies have revealed that several distinct CSC populations coexist in SCC and that tumor initiation and metastatic potential of these populations can be uncoupled. Therefore, it is critical to understand CSC biology to develop novel CSC-targeted therapies for patients with SCC with poor prognoses. This review compares the properties of CSCs in SCC with normal stem cells in the skin, summarizes current advances and characteristics of CSCs, and considers the challenges for CSC-targeted treatment of SCC.

Abstract
The management of inflammatory bowel disease (IBD) has changed since the mid-1990s (e.g., use of thiopurines/anti-TNFα agents, improved surveillance programs), possibly affecting cancer risk. To establish current cancer risk in IBD, updates are warranted from cohorts covering this time span, and detailed enough to study associations with phenotype and medication. We studied intestinal-, extra-intestinal- and overall cancer risk in the Dutch population-based IBDSL cohort. In total, 1,157 Crohn's disease (CD) and 1,644 ulcerative colitis (UC) patients were diagnosed between 1991 and 2011, and followed until 2013. Standardized incidence ratios (SIRs) were calculated for CD and UC separately, as well as for gender-, phenotype-, disease duration-, diagnosis era- and medication groups. We found an increased risk for colorectal cancer in CD patients with colon involvement (SIR 2.97; 95% CI 1.08-6.46), but not in the total CD or UC population. In addition, CD patients were at increased risk for hematologic- (2.41; 1.04-4.76), overall skin- (1.55; 1.06-2.19), skin squamous cell- (SCC; 3.83; 1.83-7.04) and overall cancer (1.28; 1.01-1.60), whereas UC patients had no increased risk for extra-intestinal- and overall cancer. Finally, in a medication analysis on CD and UC together, long-term immunosuppression exposure (>12 months) was associated with an increased risk for hematologic cancer, non-Hodgkin lymphoma, SCC and overall cancer, and this increase was mainly attributed to thiopurines. IBD patients with long-term immunosuppression exposure can be considered as having a higher cancer risk, and our data support the advice in recent IBD guidelines to consider skin cancer screening in these patients.

Abstract
Non-melanoma skin cancers represent a major cause of morbidity after organ transplantation. Squamous cell carcinomas (SCC) are the most common cutaneous malignancies seen in this population, with a 65-100 fold greater incidence in organ transplant recipients compared to the general population. In recent years, human papillomaviruses (HPV) of the beta genus have been implicated in the pathogenesis of post-transplant SCCs. The underlying mechanism of carcinogenesis has been attributed to the E6 and E7 proteins of HPV. Specific immunosuppressive medications, such as the calcineurin inhibitors and azathioprine, are associated with a higher incidence of post-transplant SCCs compared to other immunosuppressive agents. Compared to other immunosuppressives, mTOR inhibitors and mycophenolate mofetil have been associated with a decreased risk of developing post-transplant non-melanoma skin cancers. As a result, they may represent ideal immunosuppressive medications in organ transplant recipients. Treatment options for post-transplant SCCs include surgical excision, Mohs micrographic surgery, systemic retinoid therapy, adjunct topical therapy, electrodessication and curettage, and radiation therapy. This review will discuss the epidemiology, risk factors, and management options of post-transplant SCCs. In addition, the underlying mechanisms of beta-HPV mediated carcinogenesis will be discussed.
