Abstract
Nephrotoxicity as a cause of acute kidney injury (AKI) induced by cisplatin (CP), limits its usefulness as an anticancer agent. Diminazene, an angiotensin converting enzyme 2 activator, exhibited renoprotective properties on rat models of kidney diseases. This research aims to investigate the salutary effect of diminazene in comparison with lisinopril or valsartan in CP-induced AKI. The first and second groups of rats received oral vehicle (distilled water) for 9 days, and saline injection or intraperitoneal CP (6 mg/kg) on day 6, respectively. Third, fourth, and fifth groups received intraperitoneal injections of CP on day 6 and diminazene (15 mg/kg/day, orally), lisinopril (10 mg/kg/day, orally), or valsartan (30 mg/kg/day, orally), for 9 days, respectively. 24h after the last day of treatment, blood and kidneys were removed under anesthesia for biochemical and histopathological examination. Urine during the last 24 h before sacrificing the rats was also collected. CP significantly increased plasma urea, creatinine, neutrophil gelatinase-associated lipocalin, calcium, phosphorus, and uric acid. It also increased urinary albumin/creatinine ratio, N-Acetyl-beta-D-Glucosaminidase/creatinine ratio, and reduced creatinine clearance, as well the plasma concentrations of inflammatory cytokines [plasma tumor necrosis factor-alpha, and interleukin-1beta], and significantly reduced antioxidant indices [catalase, glutathione reductase , and superoxide dismutase]. Histopathologically, CP treatment caused necrosis of renal tubules, tubular casts, shrunken glomeruli, and increased renal fibrosis. Diminazine, lisinopril, and valsartan ameliorated CP-induced biochemical and histopathological changes to a similar extent. The salutary effect of the three drugs used is, at least partially, due to their anti-inflammatory and antioxidant effects. Keywords: Cisplatin, Diminazene, ACE2 activator, Lisinopril, Valsartan, Acute kidney injury.

Abstract
Outcome prediction for live-donor kidney transplantation improves clinical and patient decisions and donor selection. However, the concurrently used models are of limited discriminative or calibration power and there is a critical need to improve the selection process. We aimed to assess the value of various artificial intelligence (AI) algorithms to improve the risk stratification index. We evaluated pre-transplant variables among 66 914 live-donor kidney transplants (performed between 01/12/2007-01/06/2021) from the United Network of Organ Sharing database, randomized into training (80%) and test (20%) sets. The primary outcome measure was death-censored graft survival. We tested four machine learning models for discrimination (time-dependent concordance index, CTD, and area under the ROC curve) and calibration (integrated Brier score, IBS). We used decision curve analysis to assess the potential clinical utility. Among the models, the deep Cox mixture model showed the best discriminative performance (AUC = 0.70, 0.68, and 0.68 at 5, 10, and 13 years post-transplant, respectively). CTD reached 0.70, 0.67, and 0.66 at 5, 10, and 13 years post-transplant. The IBS score was 0.09, indicating good calibration. In comparison, applying the Living Kidney Donor Profile Index (LKDPI) on the same cohort produced a CTD of 0.56 and an AUC of 0.55-0.58 only. Decision curve analysis showed an additional net benefit compared to the LKDPI, 'Treat all' and 'Treat None' approaches. Our AI-based deep Cox mixture model, termed Live-Donor Kidney Transplant Outcome Prediction outperforms existing prediction models, including the LKDPI, with the potential to improve decisions for optimum live donor selection by ranking potential transplant pairs based on graft survival. This model could be adopted to improve the outcomes of paired exchange programs.

Abstract
In kidney transplantation, pairing recipients with the highest longevity with low-risk allografts to optimize graft-donor survival is a complex challenge. Current risk prediction models exhibit limited discriminative and calibration capabilities and have not been compared to modern decision-assisting tools. We aimed to develop a highly accurate risk-stratification index using artificial intelligence (AI) techniques. Using data from the UNOS database (156,749 deceased kidney transplants, 2007-2021), we randomly divided transplants into training (80%) and validation (20%) sets. The primary measure was death-censored graft survival. Four machine learning models were assessed for calibration (integrated Brier score [IBS]) and discrimination (time-dependent concordance [CTD] index), compared with existing models. We conducted decision curve analysis and external validation using UK Transplant data. The Deep Cox mixture model showed the best discriminative performance (area under the curve [AUC] = 0.66, 0.67, and 0.68 at 6, 9, and 12 years post-transplant), with CTD at 0.66. Calibration was adequate (IBS = 0.12), while the kidney donor profile index (KDPI) model had lower CTD (0.59) and AUC (0.60). AI-based D-TOP outperformed the KDPI in evaluating transplant pairs based on graft survival, potentially enhancing deceased donor selection. Advanced computing is poised to influence kidney allocation schemes.

Abstract
Abstract Environmental contamination with heavy metals is a threat to the organisms due to their toxicity, persistence and bioaccumulation in food chains. The study was aimed to assess cadmium (Cd) effect on calcium (Ca) level in bones of a freshwater fish Channa gachua. 42 fish individuals were kept into six (6) aquaria; labelled aq.0, 1, 2, 3,4 and 5 in the laboratory for treatment. Aq.0 was control group and aq.1, 2,3,4,5 were experimental with treatment solution of Cd 0, 0.1ppm, 0.5ppm, 1ppm, 2.5ppm and 5ppm respectively for three months. After exposure, bones tissue were examined for Cd accumulation and Ca concentration. Highest accumulation of Cd were recorded in aq.5 mean 46.86 ± 0.46 mgkg-1 .and lowest in the control group with mean 0.61 ± 0.06 mgkg-1. The order of Cd bioaccumulation in bones were aq.5 > aq.4 >aq.3 > aq.2 > aq.1 > aq.0. Highest concentration of Ca were noted in aq.0 (Control group) mean 7888.06 ± 4827.22 mgkg-1 and lowest were 1132.36 ± 203.73 mgkg-1 in aq.5 (at 5.0 ppm). Generally a pattern of decreasing Ca level were observed with each rise of Cd bioaccumulation aq.0 > aq.1 > aq.2 > aq.3 > aq.4 > aq.5. Current study indicated that Cd accumulation have substantial effect on Ca level in bones and hence on skeleton system. Strict rules must be implemented by government to control metals pollution and exploitations of biota.

Abstract
INTRODUCTION The aim of this study is to assess the outcomes of different induction therapies among mild to moderate immunological risk kidney transplants in the era tacrolimus and mycophenolate-derivate based maintenance. METHODS This was a retrospective cohort study using data from the United States Organ Procurement and Transplantation Network among mild to moderate immunological risk living-donor KTRs, defined as having first transplant and panel reactive antibodies less than 20% but with two HLA-DR mismatches. KTRs were divided into two groups based on induction therapy with either thymoglobulin or basiliximab. Instrumental variable regression models were used to assess the effect of induction therapy on acute rejection episodes, serum creatinine levels and graft survival. RESULTS Of the entire cohort, 788 patients received basiliximab while 1727 patients received thymoglobulin induction. There were no significant differences between basiliximab versus thymoglobulin induction in acute rejection episodes at one-year post-transplant (coefficient= -0.229, p value = .106), serum creatinine levels at one-year post-transplant (coefficient= -0.024, p value = .128) or death-censored graft survival (coefficient: - <0.001, p value = .201). CONCLUSION This study showed no significant difference in acute rejection episodes or graft survival when using thymoglobulin or basiliximab in mild to moderate immunological risk living donor KTRs, maintained on tacrolimus and mycophenolate-based immunosuppressive regimen.

Abstract
The poultry industry generates a lot of waste, including dead birds, manure, and poultry litter. Poultry waste should never be disposed of improperly because it can seriously harm the environment. The waste can be recycled as a feedstock for use in poultry feed by composting the litter and deceased birds. The compositional profile and organoleptic properties of the meat of growing Japanese quail were examined over the course of a 4-week trial to ascertain the effect of adding compost to the diet. In a completely randomized design (CRD), 1200 newly hatched quail chicks (Coturnix coturnix japonica) were divided into five treatment groups (diets with 0, 2.5, 5, 7.5, and 10% compost), each consisting of 40 birds with six replicates. The addition of compost to the diet had no noticeable effects on the organoleptic qualities of appearance, color, aroma, taste, texture, juiciness, tenderness, and acceptability (P>0.05). The compositional profile characteristics for chicks given compost at any level compared to chicks fed the control diet showed no differences (P>0.05). These findings suggest that the sensory characteristics and compositional profile of growing meat quails can be maintained when fed diets including up to 10% compost.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is a prevalent health condition that commonly affects adolescent girls and young women. The purpose of this study was to evaluate the correlation between levels of total glutathione (TG), reduced glutathione (GSH), superoxide dismutase (SOD), lipid peroxidation, and homocysteine with PCOS. PATIENTS AND METHODS This study employed a cross-sectional case-control design, involving a target population of 305 Sudanese females. Among them, 205 individuals were categorized as cases, and 100 served as controls. The TG, GSH, SOD, lipid peroxidation, and homocysteine levels were measured in the serum of study participants through enzyme-linked immunosorbent essay. RESULTS Total glutathione (1,174.5 ± 271.4 vs. 986.1 ± 191.5, p = 0.01), GSH (801.3 ± 132.2 vs. 748.6 ± 103.1, p = 0.007), SOD (225.2 ± 57.8 vs. 195.5 ± 49.6, p = 0.009), lipid peroxidation (3.4 ± 1.1 vs. 2.4 ± 0.7, p = 0.03), and homocysteine (14.9 ± 2.1 vs. 13.5 ± 1.6, p = 0.04), showed significant differences between the two groups (cases vs. controls). A moderate positive correlation between TG, GSH, SOD, lipid peroxidation, homocysteine, BMI, age, and duration of PCOS was observed. Furthermore, a strong positive correlation between BMI, age, and duration of PCOS was noted within the patient group. CONCLUSIONS In conclusion, this study demonstrates that patients with PCOS have elevated levels of TG, GSH, SOD, lipid peroxidation, and homocysteine compared to the control group. These findings suggest a potential association between PCOS and oxidative stress, lipid metabolism, and homocysteine pathways. Moreover, the observed positive correlation with BMI, age, and duration of PCOS indicates the importance of these factors in disease progression.

Abstract
PURPOSE/OBJECTIVE(S) To investigate the tolerance level and toxicity for standard of care treatment for oropharyngeal cancer (OP) in elderly patients and their impact on outcomes. MATERIALS/METHODS Using our in-house head and neck cancer database, we looked for non-metastatic OP cases that received definitive treatment between 1/2009-6/2020. All patients received either definitive radiation therapy (RT) +/- concomitant systemic therapy (ST), or surgery followed by adjuvant RT or RT-ST. For the elderly (age at diagnosis ≥65 years) and young (<65 years) patients, we compared treatment package time (TPT) (time from surgery to RT conclusion) for adjuvant RT, total RT duration and unplanned RT interruptions. ST details and dose/protocol modifications were also compared. We evaluated worst grade of pain and mucositis, hospitalization for non-hydration causes and febrile neutropenia (FN) during RT. Feeding tube (FT) use and weight loss were compared. The independent effect of these indicators on locoregional (LRFS), distant (DRFS) recurrence free and overall (OS) survival was assessed using multivariate analyses (MVA). RESULTS A cohort of 326 patients was included: 36% elderly (n = 118) and 64% young (n = 208), with no differences in AJCC stage distribution (8th), treatment received and HPV status (HPV+ve: 73% vs 74.6%; p = 0.86). In 23.6 % who received adjuvant RT, median TPT was 86 (range 72-128) and 81 (65-137) days for elderly vs young (p = 0.27); whereas in the definitive RT cases 76.4%, total RT duration was 49 days for both age groups. Overall, prescribed RT course was not completed in 4% and unplanned RT interruptions occurred in 22.8% and both were non-significant between age groups. Among the 261 patients that received ST, elderly utilized more cetuximab (26 vs 12%; p = 0.007). For those who received cisplatin, 20% of elderly had cumulative dose <200 mg/m2 compared to 6% among the younger age group (p = 0.006); and cisplatin was changed to carboplatin or cetuximab in 18% vs 8% (p = 0.019). Delayed/cancelled cycles and dose reductions were similar. There were more hospitalizations (47% vs 27%; p<0.001) and a trend for more FN (9% vs 3%; p = 0.09) with older age, while worst pain and mucositis was similar. FTs were used more in elderly patients (64% vs 50%; p = 0.02), for a median of 97 vs 64 days (p = 0.31); of which 19.5% vs 11% (p = 0.28) were inserted before RT start. However, % weight loss was non-significant. On MVA, longer RT duration, FT use and hospitalizations predicted worse LRFS and DRFS; and they were prognostic for OS in addition to TPT >90 days (p<0.05 for all). Nevertheless, elderly vs young had non-significant 3-year LRFS (91% vs 90% and 67% vs 69%), DRFS (86% vs 90% and 79% vs 81%) & OS (85% vs 81% and 39% vs 52%) for HPV+ve and HPV-ve respectively (p>0.05). CONCLUSION Elderly patients with OP need more multi-disciplinary supportive care when receiving RT and concurrent ST. However, survival outcomes are equivalent to younger patients. Ongoing studies should enroll more elderly candidates and stratify endpoints with age.

Abstract
PURPOSE/OBJECTIVE(S) Patients with R/R acute leukemia after allogeneic hematopoietic cell transplant (alloHCT) have a dismal prognosis with 3-year survival rates of < 20%. To improve outcomes, innovative targeted forms of organ sparing radiotherapy, such as tumor-specific RIT and TMLI, are needed to dose escalate with acceptable toxicities, especially in patients ≥ age 60 years who cannot tolerate total body irradiation (TBI) / myeloablative regimens and who have a poor prognosis. CD25 is an ideal RIT target given its expression in acute leukemias, association with poor prognosis, and expression by leukemia stem cells. In this phase I trial (NCT05139004) we hypothesized that combining dose escalated 90Y-anti-CD25 RIT with fixed dose TMLI 12 Gy, fludarabine (flu), and melphalan (mel) in patients with R/R disease is safe and associated with acceptable toxicities. MATERIALS/METHODS The primary objective of this trial is to determine the maximum tolerated dose and recommended phase 2 dose of 90Y-anti-CD25 Mab (Day -15) with 12 Gy TMLI (1.5 Gy twice a day, days -8 to -5), flu (30 mg/m2/d days -5 to -2), and mel (100 mg/m2, day -2) in patients ≥ 60 years old or with a HCT-comorbidity index ≥ 2 and with R/R AML, ALL or myelodysplastic syndrome (MDS) scheduled to undergo alloHCT from a matched donor. TMLI mean organ dose constraints for kidney, lung and liver were 4 Gy. Planned dose levels of 90Y-anti-CD25 were 0.3, 0.4, and 0.5 mCi/kg. 111In-anti-CD25 (5 mCi) was co-infused followed by serial nuclear scans to assess dosimetry and biodistribution. RESULTS To date 5 patients (ages 31-74) with R/R AML have been treated. Marrow and circulating blasts ranged from 10-36% and 9-44%, respectively. For the 3 patients at 0.3 mCi/kg, follow-up ranged from 89-191+ days. 90Y/111In-anti-CD25 nuclear scans demonstrated persistent uptake in bone out to 144 hours, which was associated with a decline in circulating blasts. After combined RIT and TMLI, mean doses (Gy) to lungs ranged from 5.7-6.5, to kidneys from 7.5-8.2 and to liver from 7.2-11.6. No dose-limiting toxicities (DLT) were observed. All 3 patients achieved CR on day +30 bone marrow biopsies and 2 remained in CR on day +90 biopsies. Two patients have recently been treated at the 0.4 mCi/kg dose level. The results of patients treated at the higher dose levels will be provided. CONCLUSION Dose escalation by adding 90Y-anti-CD25 RIT at 0.3 mCi/kg to 12 Gy TMLI was safe, including in older patients, with no dose-limiting toxicities, mean critical organ doses lower than conventional myeloablative TBI, and encouraging response rates. The toxicity profile and dose estimates at 0.3 mCi/kg predict that the planned higher dose levels will also be feasible with acceptable toxicities. RIT and TMLI are complementary and when combined address the limitations of each modality. Combining these targeted therapies may be a superior strategy to intensify dose to leukemia compared to dose escalation of either modality alone.

Abstract
Minimizing leakage from computational states is a challenge when using many-level systems like superconducting quantum circuits as qubits. We realize and extend the quantum-hardware-efficient, all-microwave leakage reduction unit (LRU) for transmons in a circuit QED architecture proposed by Battistel et al. This LRU effectively reduces leakage in the second- and third-excited transmon states with up to 99% efficacy in 220 ns, with minimum impact on the qubit subspace. As a first application in the context of quantum error correction, we show how multiple simultaneous LRUs can reduce the error detection rate and suppress leakage buildup within 1% in data and ancilla qubits over 50 cycles of a weight-2 stabilizer measurement.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) has been the most talked-about disease of the past few years. Patients with significant comorbidities have been at particular risk of adverse outcomes. This study looked at the outcomes and risk factors for adverse outcomes among patients on chronic hemodialysis for end-stage renal disease, a group of patients known to be particularly susceptible to infectious complications.
AIM To assess outcomes and risk factors for adverse outcomes of COVID-19 infection among patients on chronic hemodialysis.
METHODS We searched PubMed/MEDLINE, EMBASE, Reference Citation Analysis (https://www.referencecitationanalysis.com/) and Web of Science databases for relevant terms and imported the results into the Covidence platform. From there, studies were assessed in two stages for relevance and quality, and data from studies that satisfied all the requirements were extracted into a spreadsheet. The data was then analyzed descriptively and statistically.
RESULTS Of the 920 studies identified through the initial database search, only 17 were included in the final analysis. The studies included in the analysis were mostly carried out during the first wave. We found that COVID-19 incidence among patients on hemodialysis was significant, over 10% in some studies. Those who developed COVID-19 infection were most likely going to be hospitalized, and over 1 in 5 died from the infection. Intensive care unit admission rate was lower than the infection lethality rate. Biochemical abnormalities and dyspnea were generally reported to be associated with adverse outcomes.
CONCLUSION This systematic review confirms that patients on chronic hemodialysis are very high-risk individuals for COVID-19 infections, and a significant proportion was infected during the first wave. Their prognosis is overall much worse than in the general population, and every effort needs to be made to decrease their exposure.

Abstract
The emergence of multidrug-resistant (MDR) bacteria is a danger to public health and exposes patients to high risk, increasing morbidity and mortality worldwide. For this purpose, three months of evaluation of MDR’s prevalence and antimicrobial susceptibility patterns in the military regional university hospital of Constantine from different services and samples was carried out. Among a total of 196 isolates, 35.2% were MDR. The use of essential oils such as Origanum glandulosum Desf. as an alternative to antibiotics is attractive due to their rich content of bioactive compounds conferring many biological activities. Also, to overcome the drawbacks of using oils as the hydrophobicity and negative interaction with the environmental conditions, in addition to increasing their activity, encapsulation for the oil was performed using high-speed homogenization (HSH) into nanocapsules and high-pressure homogenization (HPH) into nanoemulsion. Nine volatile constituents were determined using gas chromatography-mass spectrometry analysis (GC-MS) in hydrodistilled oil with thymol, carvacrol, p-cymene, and γ-terpinene as dominants. A dramatic decrease in the major volatile components was observed due to the use of HSH and HPH but generated the same oil profile. The mean particle size of the nanoemulsion was 54.24 nm, while that of nanocapsules was 120.60 nm. The antibacterial activity of the oil and its nanoparticles was estimated on MDR isolates using the disk diffusion, aromatogram, and broth microdilution methods. Consistent with the differences in volatile constituents, the oil exhibited a higher antibacterial activity compared to its nanoforms with the diameters of the inhibition zone against E. coli (20 mm), S. aureus (35 mm), and A. baumannii (40 mm). Both formulations have shown relatively significant activity against the biofilm state at sub-inhibitory concentrations, where nanoemulsion was more potent than nanocapsules. The results obtained suggested that nanoformulations of essential oils are strongly recommended for therapeutic application as alternatives to antibiotics.

Abstract
Abstract
Study question
We investigated the effect of monitoring and follow-up of serum progesterone, estradiol & luteinizing hormone levels and progesterone supplement adjustments on pregnancy outcomes for FET in programmed HRT cycles.
Summary answer
Monitoring and follow-up of different hormones in patient’s serum in programmed frozen embryo transfer cycles didn’t have an impact on overall pregnancy rate.
What is known already
Frozen Embryo transfer treatment rapidly expanded in recent years. FET can effectively prevent IVF associated complications, such as ovarian hyperstimulation syndrome and multiple pregnancy. In addition, FET serves as a safe & cost-effective way to increase cumulative pregnancy rate.
Though progesterone levels on the day of transfer have not yet been studied extensively in humans, tailoring the time of transferring a frozen embryo based on serial P4 values rather than cycle day number alone results in higher pregnancy rates.The value of measuring the serum E2 levels on the day of embryo transfer as an indicator for clinical pregnancy is still doubtful.
Study design, size, duration
Six Hundred FETs were performed in a randomized prospective manner in an infertility center in Alexandria starting from 2019 till 2021.These were further subdivided based on computer randomization into Group I (Non-intervention) including300 patients with only ultrasound monitoring & Group II (intervention) including 300 patients with monitoring of serum level of progesterone, estrogen & luteinizing hormone as well as progesterone supplement adjustments.
Participants/materials, setting, methods
Group I (Non-intervention) including300 patients with only ultrasound monitoring & Group II (intervention) including 300 patients with monitoring of serum level of progesterone, estrogen & luteinizing hormone as well as progesterone supplement adjustments which are further subdivided into three groups depending on progesterone level in patient’s serum early in the morning prior to embryo transfer. Group II A: P4 levels < 5ng/dl, Group II B: P4 levels 5-10ng/dl, Group II C: P4 levels >10ng
Main results and the role of chance
Live birth and overall pregnancy rate showed no significant difference among group monitored with ultrasound only compared to the hormonal monitored group. However, on the day of embryo transfer, serum P4 > 11.83 ng/ml represented a cut-off value above which there is marked increase in OPR/LBR and a sensitivity of 53.7% & specificity of 51.2% in predicting pregnancy. Also, serum E2 value more than 292 pg/ml at day 18 demonstrated an increase in OPR/LBR.In our study, the cut off value of LH level less than of 10.8 IU/L at day13 had a sensitivity of 58.3% & specificity of 50.4% in predicting pregnancy. Regarding pregnancy outcome, monitoring of LH levels didn’t generate useful data with no added prognostic value.Conclusion: Monitoring and follow-up of different hormones in patient’s serum in programmed frozen embryo transfer cycles didn’t have an impact on live birth, overall pregnancy & abortion rate when compared to ultrasound only in non-intervention group.
Limitations, reasons for caution
Patients in non-intervention group didn’t have a hormonal pre-transfer assessment so it’s not possible to determine if the progesterone levels are suboptimal or not when compared to intervention group.
Also, we didn’t have a post transfer hormonal assessment in case group to determine whether the progesterone dose reached desired levels.
Wider implications of the findings
Kofinas et al. proposed in his study that in order to optimize pregnancy and rate, P4 levels in FET cycles should be sustained between 10 and 20 ng/ml.
This was in accordance to our study where the cut off value of P4 on day of 11.83 ng/ml optimized pregnancy rates.

Abstract
The Agrobacterium-mediated floral dip protocol is the most extensively used transformation method for a model plant Arabidopsis thaliana. Several useful methods for Agrobacterium tumefaciens-mediated transformations of Arabidopsis are existing, but they are time consuming and with low transformation efficiency. Here, we developed a transgenic Arabidopsis lines TET12p::TET12-RFP in a short period of time and enhanced transformation efficiency by using a modified transformation method by applying drought stress after floral dip. In this protocol, Agrobacterium cells carrying TET12p::TET12-RFP recombinant vectors were resuspended in a solution of 5% sucrose, 0.05% (v/v) silwet L-77 to transform female gametes of developing Arabidopsis inflorescences. Treated Arabidopsis were then applied with different levels of drought stresses to stimulate plants for the utilization of maximum plant energy in seed maturation process. The applied stresses achieved the fast maturation of already treated inflorescences while stopped the growing of newly arising untreated inflorescence, thus decreased the chances of wrong collection of untransformed seeds. Consequently, the collected seeds were mostly transgenic with a transformation frequency of at least 10%, thus the screening for positive transformants selection was more advantageous on a selective medium as compared to a classical floral dip method. Within 2-3 months, two hundred of individual transgenic plants were produced from just 10 infiltrated plants. This study concludes that application of drought stresses in a specific stage of plant is a beneficial strategy for achieving the transgenic Arabidopsis in a short period of time with high transformation efficiency.

Abstract
BACKGROUND AND AIMS Functional capacity (FC) is known to affect morbidity and mortality in kidney transplantation. Despite this important role, little is known about the variables influencing post-transplant FC. Our study aims at identifying these crucial associations. METHOD Our study included 16,684 renal transplant recipients (RTR). Patients had transplant between 1 September 2018 and 1 September 2019. Mild functional impairment was defined as those with a KPSS score > or = 80; moderate functional impairment was defined as those with a KPSS score between 50 and 70 and severe functional impairment was defined as those with a KPSS score < or =40. The outcome measured was FC at follow-up one-year post-transplant. Abnormal FC at follow-up was defined as those with KPSS score less than 80%. Normal FC at follow-up was defined as those with KPSS score equal or above 80%. Multivariate logistic regression was used to assess with the relationship between patient characteristics and abnormal functional status post-transplant. RESULTS Three groups were identified; those with none-to-mild functional impairment at time of transplant (Group A; n = 8388), those who had moderate impairment at time of transplant (Group B; n = 7694) and those who had severe impairment at time of transplant (Group C; n = 602). Abnormal FC at one-year post transplant was present in 7.69%, 28.89%, 49.49% of patients in group A, B and C, respectively. Glucocorticoid withdrawal was associated with lower risk of developing abnormal FC post-transplant (OR = 0.75, p value = .02, 95% confidence intervals: 0.64 to 0.97), while recipient diabetes was associated with higher risk of abnormal FC (OR = 1.44, p value <.01, 95% confidence intervals: 1.20 to 1.74) in adjusted model. CONCLUSION Kidney transplantation is associated with substantial improvement in all stages of FC in KTRs. Glucocorticoid withdrawal and diabetes mellitus are potentially modifiable factors of FC and merit further considerations during pre-transplant workup and post-transplant immunosuppressive therapeutic planning.Key messagesKidney transplantation is associated with substantial improvement in all stages of FC in KTRs.Glucocorticoid withdrawal and diabetes mellitus are potentially modifiable factors of FC and merit further considerations during pre-transplant workup and post-transplant immunosuppressive therapeutic planning.

Abstract
Introduction/Objective
The identification of plasmacytoid cells on rapid assessment leads to a wide range of differential diagnoses.
Methods/Case Report
We present a 51-year-old female with a parotid mass and cervical lymphadenopathy. The fine needle aspiration biopsy of the lymph node showed clusters of plasmacytoid cells. Flow cytometric studies showed cells positive for CD19, CD45, CD138 and kappa, but negative for CD38 and lambda. The kappa to lambda ratio was greater than 100. Histological sections showed plasmacytoid cells that were positive for AE1/AE3, S100, and SOX10, weakly positive for CK7 and GATA3, but negative for CD79a, CD45, EMA, p40, p63, and pan-melanoma markers. Kappa and lambda had a 1:1 ratio. Due to the discrepancy between the flow cytometric results and the immunohistochemistry, excision was recommended. The subsequent excision specimen showed classic morphology for myoepithelial carcinoma, plasmacytoid variant.
Results (if a Case Study enter NA)
NA
Conclusion
Myoepithelial carcinomas of the salivary glands are rare neoplasms, and they have various morphologies. The plasmacytoid variant can pose as a diagnostic pitfall. In fine needle aspiration biopsies, carcinoma cells with plasmacytoid morphology can be confused with a plasma cell neoplasm. CD138 is nonspecific marker, and it can be expressed in plasma cells as well as carcinomas. To further complicate matters, pancytokeratin and SOX10 can aberrantly expressed in some plasma cell myelomas. Flow cytometry studies is a valuable tool to define various cell types. However, it can be misleading if it is used as a sole source for interpreting plasmacytoid cells. Epithelial and myoepithelial neoplasms should be considered as differential diagnoses when CD138-positive plasmacytoid cells are encountered. Extended immunohistochemistry panel including multiple epithelial and myoepithelial markers play pivotal role in settling the diagnosis.

Abstract
Honey is a suitable matrix for the evaluation of environmental contaminants including organochlorine insecticides. The present study was conducted to evaluate residues of fifteen organochlorine insecticides in honey samples of unifloral and multifloral origins from Dir, Pakistan. Honey samples (5 g each) were extracted with GC grade organic solvents and then subjected to Rotary Evaporator till dryness. The extracts were then mixed with n-Hexane (5 ml) and purified through Column Chromatography. Purified extracts (1μl each) were processed through Gas Chromatograph coupled with Electron Capture Detector (GC-ECD) for identification and quantification of the insecticides. Of the 15 insecticides tested, 46.7% were detected while 53.3% were not detected in the honey samples. Heptachlor was the most prevalent insecticide with a mean level of 0.0018 mg/kg detected in 80% of the samples followed by β-HCH with a mean level of 0.0016 mg/kg detected in 71.4% of the honey samples. Honey samples from Acacia modesta Wall. were 100% positive for Heptachlor with a mean level of 0.0048 mg/kg followed by β-HCH with a mean level of 0.003 mg/kg and frequency of 83.3%. Minimum levels of the tested insecticides were detected in the unifloral honey from Ziziphus jujuba Mill. Methoxychlor, Endosulfan, Endrin and metabolites of DDT were not detected in the studied honey samples. Some of the tested insecticides are banned in Pakistan but are still detected in honey samples indicating their use in the study area. The detected levels of all insecticides were below the Maximum Residue Levels (MRLs) and safe for consumers. However, the levels detected can cause mortality in insect fauna. The use of banned insecticides is one of the main factors responsible for the declining populations of important insect pollinators including honeybees.

Abstract
We investigate the magnetic properties of amorphous Sm10Co90/Co60(Al70Zr30)40/Co85(Al70Zr30)15exchange-spring magnet trilayers. The magnetically soft Co85(Al70Zr30)15layer is coupled to the magnetically hard Sm10Co90layer through the weakly magnetic low-TcCo60(Al70Zr30)40spacer layer. The strength of the coupling can be controlled with temperature and the coupling persists above the intrinsicTcof the spacer layer due to a long-range magnetic proximity effect. Polarized neutron reflectivity is used to examine the magnetic profile of the trilayers during magnetization reversal. A two-step switching occurs, with the switching angle of the soft layer strongly dependent on the strength of the coupling. In the strong coupling regime a magnetic state can be achieved where the soft layer magnetization is perpendicular to the hard layer whereas in the weak coupling regime the soft layer reverses fully.

Abstract
A comparative study of volatile constituents, antioxidant activity, and molecular docking was conducted between essential oils from Mentha longifolia L., Mentha spicata L., and Origanum majorana L., widely cultivated in Madinah. The investigation of volatile oils extracted by hydrodistillation was performed using Gas Chromatography-Mass Spectrometry (GC-MS). A total number of 29, 42, and 29 components were identified in M. longifolia, M. spicata, and O. majorana representing, respectively, 95.91, 94.62, and 98.42, of the total oils. Pulegone (38.42%), 1,8-cineole (15.60%), menthone (13.20%), and isopulegone (9.81%) were the dominant compounds in M. longifolia oil; carvone (35.14%), limonene (27.11%), germacrene D (4.73%), and β-caryophyllene (3.02%) were dominant in M. spicata oil; terpin-4-ol (42.47%), trans-sabinene hydrate (8.52%), γ-terpinene (7.90%), α-terpineol (7.38%), linalool (6.35%), α-terpinene (5.42%), and cis-sabinene hydrate (3.14%) were dominant in O. majorana oil. The antioxidant activity, assessed using DPPH free radical–scavenging and ABTS assays, was found to be the highest in O. majorana volatile oil, followed by M. spicata and M. longifolia, which is consistent with the differences in total phenolic content and volatile constituents identified in investigated oils. In the same context, molecular docking of the main identified volatiles on NADPH oxidase showed a higher binding affinity for cis-verbenyl acetate, followed by β-elemene and linalool, compared to the control (dextromethorphan). These results prove significant antioxidant abilities of the investigated oils, which may be considered for further analyses concerning the control of oxidative stress, as well as for their use as possible antioxidant agents in the pharmaceutical industry.

Abstract
The supraclavicular artery flap is used for reconstruction of defects of the head and neck. One of the major implications of this procedure is injury to the nerve roots of C3 and C4 of the superficial cervical plexus, which provides sensation over the clavicle, shoulder and proximal chest, thereby causing problems in overall shoulder function. The objective of this study was to assess shoulder function, range of motion, pain, daily activities and overall satisfaction of the patient after using this flap. This study was conducted at the Department of Plastic & Reconstructive Surgery, Dow University of Health Sciences & Dr. Ruth KM Pfau Civil Hospital Karachi, Pakistan, from May 2015 to November 2018. Supraclavicular flap was used in 35 patients who underwent soft tissue reconstruction of defect of the neck after release of post burn contracture. Penn Shoulder Score and Constant Murley Score were used as assessment tools. Assessment by Penn Shoulder Score resulted in 25 (71.4%) patients within the upper quartile and 10 (18.6%) patients within the lower quartile. Constant Murley Score showed 19 (54.2%) of patients had 161°-180° shoulder abduction and lateral elevation. Forward flexion of 161°-180° was seen in 17 (48.5%) patients, 17 (48.5%) had internal rotation till the inter scapular region, 15 (42.8%) had no impairment of external rotation, 19 (54.2%) patients had no impairment of work/recreation, 25 (71.4%) had felt no change in their sleep and 22 (62.8%) were able to position their arm above their head. Overall parameters indicate better function, good range of motion, less pain, resumption of daily activities, and overall satisfaction.

Abstract
Simple tuneup of fast two-qubit gates is essential for the scaling of quantum processors. We introduce the sudden variant (SNZ) of the net zero scheme realizing controlled-Z (CZ) gates by flux control of transmon frequency. SNZ CZ gates realized in a multitransmon processor operate at the speed limit of transverse coupling between computational and noncomputational states by maximizing intermediate leakage. Beyond speed, the key advantage of SNZ is tuneup simplicity, owing to the regular structure of conditional phase and leakage as a function of two control parameters. SNZ is compatible with scalable schemes for quantum error correction and adaptable to generalized conditional-phase gates useful in intermediate-scale applications.

Abstract
INTRODUCTION The additive benefit of interleukin-2 receptor antagonist (IL2-RA) induction in standard-risk kidney transplant recipients, while maintained on tacrolimus-based immunosuppressive therapy, is uncertain. METHODS We divided the studies included in this meta-analysis into 2 groups: group A (included studies that used same dose of tacrolimus in both arms of each study) and group B (included studies that compared patients who received induction therapy and low-dose tacrolimus vs. those who received no-induction therapy and high dose of tacrolimus). RESULTS In group A, 11 studies were included (n = 2,886). IL2-RA induction therapy was not associated with significant differences in comparison to no-induction therapy in terms of acute rejection rates at 6 months post-transplant (risk ratio = 1.12 and 95% confidence interval [CI] range: 0.94-1.35) or graft survival at 1 year post-transplant (risk ratio = 0.78 and 95% CI range: 0.45-1.36). In group B, 2 studies were included (n = 669). There was no difference between both arms in terms of acute rejection rates (risk ratio = 0.62, with 95% CI range: 0.33-1.14) or graft survival (risk ratio = 1 and 95% CI range: 0.57-1.74). CONCLUSION IL2-RA induction therapy does not improve outcomes in patients maintained on tacrolimus-based immunotherapy in standard-risk population.

Abstract
Ambient air pollutants are known risk factors for cardiovascular disease (CVD) morbidity and mortality with significant racial disparities. However, few studies have explored racial differences among highly susceptible subpopulations, such as renal transplant recipients (RTRs). Despite improvements in quality of life after transplantation, CVD remains the major cause of mortality, especially among Black recipients. This study aimed to evaluate potential racial differences in the association between long-term levels of PM2.5 and the risk of all-cause, total CVD, and coronary heart disease (CHD) mortality among RTRs. This retrospective study consists of 93,857 non-smoking adults who received a renal transplant between 2001 and 2015. Time-dependent Cox regression was used to assess the association between annual concentrations of PM2.5 and mortality risk. In the multivariable-adjusted models, a 10 μg/m3 increase in ambient PM2.5 levels found increased risk of all-cause (HR = 3.45, 95% CI: 3.08-3.78), CVD (HR = 2.38, 95% CI: 1.94-2.92), and CHD mortality (HR = 3.10, 95% CI: 1.96-4.90). Black recipients had higher risks of all-cause (HR = 4.09, 95% CI: 3.43-4.88) and CHD mortality (HR = 6.73, 95% CI: 2.96-15.32). High levels of ambient PM2.5 were associated with all-cause, CVD, and CHD mortality. The association tended to be higher among Black recipients than non-Blacks.

Abstract
INTRODUCTION Vascular access thrombosis remains the Achilles Heel for many a hemodialysis patient. We performed a systematic review and meta-analysis to assess the impact of monitoring vascular access blood flow on prediction and prevention of vascular access thrombosis. We hypothesized that monitoring vascular access blood flow has a pivotal role in lowering the risk of thrombosis and subsequent access failure. METHODOLOGY We conducted a systematic review in PubMed and EMBASE databases to identify randomized studies that have assessed the effect of hemodialysis access surveillance on the risk of thrombosis. A random-effects model was used for the meta-analysis. Subgroup analysis was performed among patients with arterio-venous fistula (AV-fistulas) and those with arterio-venous graft (AV-grafts). RESULTS Ten randomized studies were included in the meta-analysis. The total number of patients included in the analysis was 1430. On performing the random-effects model among the included studies, hemodialysis access surveillance was associated with better outcomes (risk ratio = 0.73, 95% confidence interval ranges from 0.55 to 0.98). The analysis of the AV-fistula group showed an estimated overall risk ratio of 0.55 (95% confidence interval ranges from 0.33 to 0.89) favoring access surveillance. However, in the AV-grafts group, the estimated overall risk ratio was 0.92 (95% confidence interval ranges from 0.65 to 1.29) showing no additional benefit for access surveillance. CONCLUSION Hemodialysis access surveillance using access blood flow monitoring can reduce the risk of access thrombosis for patients with AV-fistulas, but this is not the case with AV-grafts.

Abstract
BACKGROUND The current listing criteria (Milan, University of California San Francisco [UCSF]) for orthotropic liver transplants (OLT) in hepatocellular carcinoma (HCC) patients emphasize the anatomic features of the tumor such as size, burden, and multiplicity. Recent reports showed that patients with large tumors may have equivalent survival to Milan criteria patients. This suggests that differences in biologic behavior of tumors may contribute to the outcome. AIM The aim of this article is to understand the impact of biologic modifiers such as alpha-fetoprotein (AFP) on survival in both Milan and UCSF HCC patients. METHODS We reviewed all liver transplants reported to the United Network for Organ Sharing between 2002 and 2013. We analyzed the survival of patients transplanted for HCC who fit the Milan criteria and those transplanted with tumors beyond Milan and within UCSF criteria. We tested various AFP level cutoffs in both groups in relationship to the 1-, 3-, and 5-year survival rates below and above the proposed cutoffs. RESULTS Survival difference was significant between Milan patients with AFP ≤ 2500 ng/mL and those with AFP > 2500 ng/mL (59.1% vs 37.4%; P < .001). The mean 5-year survival was 55% for beyond Milan within UCSF patients with AFP ≤ 150 ng/mL and 35.7% for those with AFP > 150 ng/mL (P = .003). CONCLUSION AFP level should be incorporated in the selection criteria for HCC patients considered for OLT. Milan patients with an AFP level exceeding 2500 ng/mL have reduced survival. Patients with tumors beyond Milan and within UCSF criteria whose AFP ≤ 150 ng/mL achieve acceptable 5-year survival and are good candidates for OLT.

Abstract
The most recent British Transplant Society (BTS) guidelines recommend that office blood pressure (BP) monitoring in living donors is sufficient for the assessment of hypertension (HTN) and those with BP >140/90 should be further assessed using ambulatory BP monitoring (ABPM). ABPM can detect diurnal and nocturnal variation in BP, thus it can identify masked HTN. The aim of the current study is to assess reliability of ABPM vesus office BP monitoring for assessment in living kidney donors. Office and ABPM of all potential kidney donors at a single center from April 2009 to March 2017 were retrospectively reviewed and compared. Age, sex, body mass index, kidney function, and echocardiography results were collected and analyzed. Two hundred and sixteen kidney donors were stratified based on their BP readings into four groups; group 1 (masked HTN: normotensive in office and hypertensive in ABPM), group 2 (sustained normotension: normotensive in office and in ABPM), group 3 (sustained HTN: hypertensive in office and in ABPM), group 4 (white-coat HTN: hypertensive in office and normotensive in ABPM). Thirteen percent of patients were diagnosed with masked HTN. Office systolic BP monitoring was significantly higher in patients older than 50 years old compared to other younger populations. However, this significant difference in systolic BP was diminished when assessment with ABPM was performed. In conclusion, ABPM is a reliable modality for the identification of masked HTN and white coat HTN. Masked HTN is correlated with increased risk of end organ damage and risk of death in potential kidney donors. Transplant physicians cannot rely solely on office BP monitoring in the assessment of potential living kidney donors. ABPM should be integral part of routine assessment of potential living kidney donors.

Abstract
Abstract
Introduction
Recent epidemiologic data suggests increased risk of ischaemic stroke in cancer patients. The etiology of increased ischaemic stroke is unknown. Atrial fibrillation (AF) is among the potential etiologies. The risk of AF has not been studied among cancer patients in the United States.
Purpose
Ascertain the association of AF in cancer patients in the USA by using the largest database i.e. National Inpatient Sample (NIS).
Methods
Patients ≥18 years old were selected in the NIS database for years 2010 to 2014 and stratified based on presence or absence of any of four cancers (lung, colon, breast and prostate; 4CA) using ICD 9 codes. Atrial fibrillation and stroke/TIA were also identified using ICD 9 codes. Components of CHADS2 score (CHF, hypertension, Age>75, diabetes and stroke/TIA) were identified using ICD 9 codes. χ2 tests performed for prevalence of AF in patients with or without these cancers stratified by CHADS2 score. Binary logistic regression was used to analyze individual components of CHADS2 score.
Results
AF and stroke/TIA were significantly higher among 4CA than non-4CA group (18.7% vs 12.0%, P<0.001 and 5.4% vs 4.8%, P<0.001 respectively). AF prevalence increased with CHADS2 and was significantly higher in 4CA group with CHADS2 score 0 to 4 (Table 1 and Figure 1). Logistic regression for the outcome of AF showed “Age >75” OR (3.0), CHF (2.8), CVA (1.2), HTN (1.3) and DM (1.1).
Conclusion
This is the first study using a national database of USA patients to estimate prevalence of AF in cancer patients compared to non-cancer patients and reaffirms the higher burden of AF in cancer patients. Prevalence of both AF and stroke were greater in cancer patients when stratified by CHADS2 score. This may indicate not just an increased risk of AF but an increased risk of stroke/TIA for the same CHADS2 score. Stroke incidence was also higher in the 4CA group (5.4% vs. 4.8% P<0.001). Cancer patients with CHADS2 score >1 may benefit from screening with loop recorder to identify previously undetected AF and initiate anticoagulation therapy. Prospective longitudinal studies are needed to validate this retrospective study.

Abstract
BACKGROUND AND OBJECTIVE Encapsulation is an effective method to keep the quality of and avoid changes in flavors or essential oils due to oxidation, heating, volatilization, or chemical interactions. This study aims to microencapsulate key flavorings by traditional wall materials, namely, gum arabic (GA), maltodextrin (MD) and sodium caseinate (SC) and evaluate the effects of different wall materials on the properties of the flavor microcapsules. MATERIALS AND METHODS The emulsions of flavor compounds (linalool, citral, orange oil, allyl caproate and isoamyl acetate) were prepared using GA, SC and MD as carriers with different concentrations and then encapsulated in powder form by a spray dryer. Physical properties, including encapsulation efficiency, viscosity, emulsion stability and moisture, were studied before and after the spray drying process. Moreover, the morphology and extent of the nonenzymatic browning (NEB) of powder particles were performed using a scanning electron microscope (SEM) and a chroma meter. The effect of encapsulation on flavor retention and chemical composition was evaluated using gas chromatography-mass spectrometry (GC-MS). RESULTS Orange oil shows the maximum retention efficiency (84.5-97.9%), whereas isoamyl acetate is less retained during drying (44.4-72.5%) compared with other volatile compounds. Increasing the concentration of GA provides the highest retention for all aroma compounds and improves the viscosity and the emulsion stability of spray-dried powder. The presence of MD as the main encapsulating agent enables the formation of several homogeneous capsules with a good spherical shape and a smooth surface, according to SEM. The NEB is observed intensively in encapsulated samples containing citral and orange oils, whereas the least browning occurs in isoamyl acetate microcapsules. CONCLUSION Wall material formulation affects the retention, morphology and physical properties of the encapsulated flavors, which can be used in food or nutraceutical powder premixes.

Abstract
INTRODUCTION Cognitive dysfunction is a major consequence of end-stage renal disease (ESRD) and has further detrimental effects on both functionality and the quality of life for patients. While peritoneal dialysis is generally advocated in ESRD, there is a substantial knowledge gap about the differential effects of chronic dialysis modalities on cognitive dysfunction and decline. The aim of this meta-analysis is to evaluate cognitive function in peritoneal dialysis versus hemodialysis patients. METHODS We performed a systematic review in different databases to identify studies that assessed the effect of different dialysis modalities on cognitive functions. Inclusion criteria for our meta-analysis were all studies that compared the effects of peritoneal dialysis on cognitive functions compared to intermittent hemodialysis. The data collected were the name of the first author, journal title, year of publication, country where the study was conducted, number of patients in the peritoneal dialysis and hemodialysis arms and methods of assessment of cognitive functions. RESULTS Out of 2769 abstracts reviewed in different databases, 11 papers were included in our meta-analysis. Altogether, 195,774 patients were included in the final analysis. The forest plot analysis of the rate of cognitive impairment in different dialysis modalities showed decreased risk of cognitive impairment in the peritoneal dialysis population compared to hemodialysis patients (relative risk = 0.634, confidence interval ranges from 0.508 to 0.790). There was evidence of significant heterogeneity among studies with p < 0.0001 and I2 = 85.5%. The sensitivity analysis limited to studies on patients younger than 65 years of age showed similar results (relative risk = 0.516; 95% confidence intervals: 0.379-0.704). CONCLUSION Patients on peritoneal dialysis demonstrated a lower odd of cognitive dysfunction compared to those on hemodialysis. Future prospective studies should assess cognitive decline as a meaningful outcome in dialysis patients.

Abstract
Cotton crop, plays a significant role in Pakistan's economy by ruling a prominent place in edible oil and local textile industry. Phosphorus (P) inaccessibility and deficiency of soil organic matter are the key restraints for low crop productivity in cotton. Therefore, a two years field study was designed during 2014-15, to explore the influence of phosphate solubilizing bacteria (PSB), farmyard manure (FYM), poultry manure (PM) and inanimate sources of P on various physiological, growth, yield and quality parameters of cotton crop at CCRI Multan. Field responses of seeds inoculated with two distinctive phosphate solubilizing bacteria (PSB) strains viz. S0 = control, S1 =strain-1, S2 = strain-2 and eight organic, inorganic P sources viz., P0= control, P1 = 80 kg ha-1 P from inorganic source, P2 = 80 kg ha-1 P from FYM, P3 = 80 kg ha-1 P from PM, P4 = 40 kg ha-1 P from FYM + 40 kg ha-1 P from inorganic source, P5 = 40 kg ha-1 P from PM + 40 kg ha-1 P from inorganic source, P6 = 80 kg ha-1 P from FYM + 40 kg ha-1 P from inorganic source, P7 = 80 kg ha-1 P from PM + 40 kg ha-1 P from inorganic source and P8 = 40 kg ha-1 P from FYM + 40 kg ha-1 P from PM were evaluated. Results revealed that inoculation of seeds with PSB and collective use of inorganic and organic sources of P had considerably increased the yield contributing attributes in cotton. However, the treatment P7 (80 kg P ha-1 from PM + 40 kg P ha-1 from inorganic source) in coincidence with seeds inoculated with PSB (S1) produced taller plant, maximum boll weight, significantly higher LAI and CGR. Significantly higher seed cotton yield, lint yield, fiber length and maximum BCR of 1.95 and 1.81 was also obtained from the P7 treatment during both crop-growing seasons. In conclusion, combined use of 80 kg P ha-1 from PM + 40 kg P ha-1 from inorganic source and cotton seeds inoculated with strain-1 improved phosphorus uptake ensuing in greater consumption of photo-assimilates for maximum growth and yield.

Abstract
Purpose To assess the effect of receiving a kidney with PUJ dysfunction on the recipient renal graft function. Methodology 198 patients, who underwent renal transplantation from 1st January 2004 to 31st December 2014 in a single Center in the North West of England, were retrospectively reviewed using a computerized database. Split kidney function and the PUJ dysfunction for the donors were assessed using Tc-99 m MAG3 renogram. Each recipient with PUJ dysfunction was matched with a control recipient by age, gender, and number of days after transplantation. Both groups were followed up for 3.5 years post-transplantation. Results Of the 198 recipients included in the study, 19 recipients received kidneys from donors with PUJ dysfunction. Prevalence of PUJ dysfunction was 9.5% and it was more common in males than females. There was no difference between the case group and the control group in terms of age, gender, and follow-up time post-transplantation. There was also no difference between the case group and the control group in mean creatinine (130 µmol/l and 138 µmol/l respectively, p = 0.305) or the mean eGFR (48.6 ml/min and 47.5 ml/min respectively, p = 0.054) at 3.5 year post-kidney transplantation. Conclusion This study showed that PUJ dysfunction of renal allograft has a negligible effect on graft function over 3.5 years period post-transplantation. A prospective randomized trial is needed to test these findings. In the presence of widened gap between demand and supply in renal transplantation, PUJ dysfunction in potential donors should not preclude them from donation.

Abstract
Background:System lupus erythematosus (SLE) is an autoimmune disease that is associated with skin rash and multiple organs lesion. It is known that obesity is a major factor contributing to the onset and progression of autoimmune diseases including SLE. Our previous study showed that circulating T follicular helper (Tfh) cells played an important role in autoantibody production in SLE patients. A recent study showed that Tfh cells promote B cell production of IgA antibodies, which help shape the composition of the gut microbiota and may modulate obesity.Objectives:By establishing an obesity-associated lupus mouse model, we investigated the pathophysiologic link of obesity, SLE and Tfh cells using MRL/lpr lupus prone mice.Methods:Twenty MRL/lpr mice (10 male and 10 female) were randomized equally fed with a regular diet (RD) or high fat diet (HFD, 60% calories comprised of fat). Their body weights were recorded weekly as an indicator of obesity achievement. SLE progression was monitored weekly by development of skin lesion and urine protein levels assessed by Bradford assay. Blood was collected for IgG, anti-dsDNA and anti-nuclear antibody (ANA) detection. At the endpoint of week 14, spleen was measured and weighted. Spleen, kidney, and dorsum of neck skin were collected and embedded for H&E, PAS, Masson’s staining, and immune complex staining to detect active histopathological lupus lesions and be quantified as histological skin score and kidney index. Tfh cells in spleen was identified by immunohistochemistry (IHC) staining glomerulus of kidney.Results:Obesity was achieved with a significant difference of mouse body weight between the RD and HFD groups by week 3 and continued until week 14 (p<0.05 top<0.01). Evidence of SLE development, such as skin rash on the dorsal neck and back in HFD group showed up as earlier as week 6 and occurred in 55.6% of the HFD group vs 11.1% of the RD group (p<0.05), with a higher histological score of skin in HFD group (p<0.05). Proteinuria was increased from 11 to 14 week in male HFD group with an elevated kidney index and immune-complex deposits in their glomerulus of kidney. There was an increase trend of anti-dsDNA and IgG titer in HFD group, but no difference of ANA was observed between these two groups. Splenomegaly was observed in the HFD mice (p<0.05). The Tfh cells in the spleen of HFD group were higher than RD group.Conclusion:Our results show accelerated and greater severity of lupus development in MRL/lpr mice with HFD compared to mice on RD, indicating HFD-induced obesity exacerbates lupus development in mice. Tfh cells may be involved in the relation of SLE and obesity. This model could be used to investigate the mechanism underlying the link between obesity and SLE development. Interventions to reduce body weight or target Tfh cells may improve both lupus symptoms and outcomes in genetically predisposed SLE patients.References:[1]Tedeschi S, et al.
