Abstract
BACKGROUND Nowadays, the chance of discovering the best antibody candidates for predicting clinical malaria has notably increased due to the availability of multi-sera data. The analysis of these data is typically divided into a feature selection phase followed by a predictive one where several models are constructed for predicting the outcome of interest. A key question in the analysis is to determine which antibodies should be included in the predictive stage and whether they should be included in the original or a transformed scale (i.e. binary/dichotomized). METHODS To answer this question, we developed three approaches for antibody selection in the context of predicting clinical malaria: (i) a basic and simple approach based on selecting antibodies via the nonparametric Mann-Whitney-Wilcoxon test; (ii) an optimal dychotomizationdichotomization approach where each antibody was selected according to the optimal cut-off via maximization of the chi-squared (χ2) statistic for two-way tables; (iii) a hybrid parametric/non-parametric approach that integrates Box-Cox transformation followed by a t-test, together with the use of finite mixture models and the Mann-Whitney-Wilcoxon test as a last resort. We illustrated the application of these three approaches with published serological data of 36 Plasmodium falciparum antigens for predicting clinical malaria in 121 Kenyan children. The predictive analysis was based on a Super Learner where predictions from multiple classifiers including the Random Forest were pooled together. RESULTS Our results led to almost similar areas under the Receiver Operating Characteristic curves of 0.72 (95% CI = [0.62, 0.82]), 0.80 (95% CI = [0.71, 0.89]), 0.79 (95% CI = [0.7, 0.88]) for the simple, dichotomization and hybrid approaches, respectively. These approaches were based on 6, 20, and 16 antibodies, respectively. CONCLUSIONS The three feature selection strategies provided a better predictive performance of the outcome when compared to the previous results relying on Random Forest including all the 36 antibodies (AUC = 0.68, 95% CI = [0.57;0.79]). Given the similar predictive performance, we recommended that the three strategies should be used in conjunction in the same data set and selected according to their complexity.

Abstract
SUMMARY Due to their flexibility and superior performance, machine learning models frequently complement and outperform traditional statistical survival models. However, their widespread adoption is hindered by a lack of user-friendly tools to explain their internal operations and prediction rationales. To tackle this issue, we introduce the survex R package, which provides a cohesive framework for explaining any survival model by applying explainable artificial intelligence techniques. The capabilities of the proposed software encompass understanding and diagnosing survival models, which can lead to their improvement. By revealing insights into the decision-making process, such as variable effects and importances, survex enables the assessment of model reliability and the detection of biases. Thus, transparency and responsibility may be promoted in sensitive areas, such as biomedical research and healthcare applications. AVAILABILITY AND IMPLEMENTATION survex is available under the GPL3 public license at https://github.com/modeloriented/survex and on CRAN with documentation available at https://modeloriented.github.io/survex.

Abstract
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and multiple sclerosis (MS) are two complex and multifactorial diseases whose patients experience persistent fatigue, cognitive impairment, among other shared symptoms. The onset of these diseases has also been linked to acute herpesvirus infections or their reactivations. In this work, we re-analyzed a previously-described dataset related to IgG antibody responses to 6 herpesviruses (CMV - cytomegalovirus; EBV - Epstein-Barr virus; HHV6 - human herpesvirus-6; HSV1 and HSV2 - herpes simplex virus-1 and -2, respectively; VZV - varicella-zoster virus) from the United Kingdom ME/CFS biobank. The primary goal was to report the underlying symptomology and its association with herpesvirus IgG antibodies using data from 4 disease-trigger-based subgroups of ME/CFS patients (n = 222) and patients with MS (n = 46). The secondary objective was to assess whether serological data could distinguish ME/CFS and its subgroup from MS using a SuperLearner (SL) algorithm. There was evidence for a significant negative association between temporary eye insight disturbance and CMV antibody concentrations and for a significant positive association between bladder problems and EBV antibody concentrations in the MS group. In the ME/CFS or its subgroups, the most significant antibody-symptom association was obtained for increasing HSV1 antibody concentration and brain fog, a finding in line with a negative impact of HSV1 exposure on cognitive outcomes in both healthy and disease conditions. There was also evidence for a higher number of significant antibody-symptom associations in the MS group than in the ME/CFS group. When we combined all the serological data in an SL algorithm, we could distinguish three ME/CFS subgroups (unknown disease trigger, non-infection trigger, and an infection disease trigger confirmed in the lab at the time of the event) from the MS group. However, we could not find the same for the remaining ME/CFS group (related to an unconfirmed infection disease). In conclusion, IgG antibody data explains more the symptomology of MS patients than the one of ME/CFS patients. Given the fluctuating nature of symptoms in ME/CFS patients, the clinical implication of these findings remains to be determined with a longitudinal study. This study is likely to ascertain the robustness of the associations during natural disease course.

Abstract
INTRODUCTION Venetoclax combined with azacitidine (AZA-VEN) constitutes an option for the treatment of acute myeloid leukemia. There are, however, no data on the COVID-19 incidence and outcome in patients treated with AZA-VEN. METHODS Patients with acute leukemia treated with AZA-VEN at a single institution were included in this prospective observational study. RESULTS Thirteen patients were enrolled, 46% with treatment-naïve, and 56% with relapsed/refractory disease. Fifty-four percent of patients were males; the median age was 69 years. Six patients (46%) developed COVID-19 during the observation time. The median time to COVID-19 was 24 days from the initiation of AZA-VEN. The 2-month cumulative incidence of COVID-19 was 46.2%. Two patients (33%) succumbed to COVID-19. The 100-day COVID-19-free survival from AZA-VEN initiation was 61%. The median follow-up time was 4.3 months. DISCUSSION/CONCLUSION COVID-19 constitutes a frequent complication of AZA-VEN treatment in the era of the COVID-19 pandemic, leading to death in a significant proportion of patients.

Abstract
Bing-Neel syndrome (BNS) is a rare presentation of Waldenström macroglobulinemia (WM). BNS is a consequence of the central nervous system (CNS) involvement by lymphoplasmacytic lymphoma (LPL) and, rarely, the peripheral nervous system. The data on BNS are extremely scarce. Therefore, we performed a multicenter retrospective analysis of BNS patients diagnosed and treated in centers aligned with the Polish Lymphoma Research Group. The analysis covers the years 2014–2021. Eleven patients were included, 55% females and the median age at BNS diagnosis was 61 years. The median time from WM to BNS was 3.5 years; 27% of patients did have a diagnosis of WM and BNS made simultaneously or within 30 days from each other. Isolated parenchymal involvement was the least frequent (20%). Patients were treated with different regimens, mostly able to cross the blood-brain barrier, including 18% treated with ibrutinib first line. The cumulative objective response to treatment was 73%. With the median follow-up of 20 months (95% CI, 2–32), the 36-month estimates were: overall survival (OS) 47%, progression-free survival (PFS) 33%, and cumulative incidence of BNS-associated death 41%. The performance status according to ECOG was significant for PFS (HR = 7.79) and the hemoglobin concentration below 11 g/dL was correlated with PFS. To conclude, BNS is a very rare manifestation of WM. It is associated with a poor outcome with most patients succumbing to BNS.

Abstract
In clinical practice, several standardized neuropsychological tests have been designed to assess and monitor the neurocognitive status of patients with neurodegenerative diseases such as Alzheimer’s disease. Important research efforts have been devoted so far to the development of multivariate machine learning models that combine the different test indexes to predict the diagnosis and prognosis of cognitive decline with remarkable results. However, less attention has been devoted to the explainability of these models. In this work, we present a robust framework to (i) perform a threefold classification between healthy control subjects, individuals with cognitive impairment, and subjects with dementia using different cognitive indexes and (ii) analyze the variability of the explainability SHAP values associated with the decisions taken by the predictive models. We demonstrate that the SHAP values can accurately characterize how each index affects a patient’s cognitive status. Furthermore, we show that a longitudinal analysis of SHAP values can provide effective information on Alzheimer’s disease progression.

Abstract
AbstractThe increased interest in deep learning applications, and their hard-to-detect biases result in the need to validate and explain complex models. However, current explanation methods are limited as far as both the explanation of the reasoning process and prediction results are concerned. They usually only show the location in the image that was important for model prediction. The lack of possibility to interact with explanations makes it difficult to verify and understand exactly how the model works. This creates a significant risk when using the model. The risk is compounded by the fact that explanations do not take into account the semantic meaning of the explained objects. To escape from the trap of static and meaningless explanations, we propose a tool and a process called LIMEcraft. LIMEcraft enhances the process of explanation by allowing a user to interactively select semantically consistent areas and thoroughly examine the prediction for the image instance in case of many image features. Experiments on several models show that our tool improves model safety by inspecting model fairness for image pieces that may indicate model bias. The code is available at: http://github.com/MI2DataLab/LIMEcraft.

Abstract
We describe new functionalities that have been added to an existing and widely used software solution in Polish public healthcare. The system automatically evaluates a number of medical scores. It provides epidemiologic monitoring concerning infectious diseases; classifies a particular patient to a specific risk group; and detects anomalies. Moreover, an analysis of a prescribed drug is performed.

Abstract
(1) Background: There is a constant search for new prognostic factors that would allow us to accurately determine the prognosis, select the type of treatment, and monitor the patient diagnosed with uveal melanoma in a minimally invasive and easily accessible way. Therefore, we decided to evaluate the prognostic role of its pigmentation in a clinical assessment. (2) Methods: The pigmentation of 154 uveal melanomas was assessed by indirect ophthalmoscopy. Two groups of tumours were identified: amelanotic and pigmented. The statistical relationships between these two groups and clinical, pathological parameters and the long-term survival rate were analyzed. (3) Results: There were 16.9% amelanotic tumours among all and they occurred in younger patients (p = 0.022). In pigmented melanomas, unfavourable prognostic features such as: epithelioid cells (p = 0.0013), extrascleral extension (p = 0.027), macronucleoli (p = 0.0065), and the absence of BAP1 expression (p = 0.029) were statistically more frequently observed. Kaplan−Meier analysis demonstrated significantly better overall (p = 0.017) and disease-free (p < 0.001) survival rates for patients with amelanotic tumours. However, this relationship was statistically significant for lower stage tumours (AJCC stage II), and was not present in larger and more advanced stages (AJCC stage III). (4) Conclusions: The results obtained suggested that the presence of pigmentation in uveal melanoma by indirect ophthalmoscopy was associated with a worse prognosis, compared to amelanotic lesions. These findings could be useful in the choice of therapeutic and follow-up options in the future.

The meaning of the shape of the frontal bone, facial retraction and prognathism for the degree of gracilisation of the supraorbital region in Homo sapiens. Anthropol Anz 2022; 79:341-360.

Abstract
Although the marked convexity of the frontal bone and retraction of the facial skeleton under the anterior part of the cranial base are commonly regarded as traits significantly influencing the gracilisation of the supraorbital region (a decrease in the degree of robusticity) in the Homo sapiens crania, identification of which of these two traits is more important for this phenomenon has not yet been investigated. Thus, the main aim of this study is to establish whether the frontal inclination angle (reflecting the mid-sagittal shape of the frontal bone) or the facial retraction angle (describing the grade of facial retraction) is more strongly related to the degree of gracilisation in the supraorbital region in a large sample of geographically diverse modern adult human crania (n = 250). Earlier studies based on small modern Homo sapiens cranial samples (derived from one population) demonstrated a lack of a relationship between the facial angle (reflecting the prognathism of the lower face) and the supraorbital region's expression. In this study, we also investigated whether there was no relationship between these traits in the analysed large modern human cranial sample. Spearman's rank correlations and models concerning partial rank correlations (including traits such as sex, geographic origin, size of the facial skeleton and size of the neurocranium to eliminate their influence on the examined relationships) were used. The results indicate a stronger relationship of the degree of gracilisation in the supraorbital region with the frontal inclination angle than with the angle of facial retraction (without the influence of the other considered factors). No significant relationship between supraorbital region expression and prognathism was established. The importance of the obtained results was discussed, including the evolutionary perspective and the occurrence of significant interpopulation differences in the gracilisation of the supraorbital region in modern humans.

Abstract
The sudden outbreak and uncontrolled spread of COVID-19 disease is one of the most important global problems today. In a short period of time, it has led to the development of many deep neural network models for COVID-19 detection with modules for explainability. In this work, we carry out a systematic analysis of various aspects of proposed models. Our analysis revealed numerous mistakes made at different stages of data acquisition, model development, and explanation construction. In this work, we overview the approaches proposed in the surveyed Machine Learning articles and indicate typical errors emerging from the lack of deep understanding of the radiography domain. We present the perspective of both: experts in the field - radiologists and deep learning engineers dealing with model explanations. The final result is a proposed checklist with the minimum conditions to be met by a reliable COVID-19 diagnostic model.

Abstract
Salvage autologous hematopoietic stem cell transplantation (auto-HSCT) constitutes a therapeutic option for a group of well-selected patients with relapsed multiple myeloma (MM). However, if an insufficient number of stem cells were harvested and stored before the first auto-HSCT, stem cells need to be remobilized. Patients diagnosed with MM who following relapse after auto-HSCT, had remobilization and afterward, auto-HSCT with remobilized cells were included in this retrospective analysis. Thirty-three patients, 61% males, the median age 61 years, were included. With a median follow-up of 1.8 years, 2-year progression-free survival was 56.2%, non-relapse mortality 4.8%. The 2-year cumulative incidence of t-MDS was 4.9%. Factors important for the outcome were: the quality of response, previous radiotherapy, the time between the first and salvage auto-HSCT. To conclude, salvage auto-HSCT performed with cells procured after the previous auto-HSCT can be efficacious in relapsed MM, especially if a sufficiently long response had been obtained to the first auto-HSCT(s).

Abstract
OBJECTIVES Relapse of myelodysplastic syndromes (MDS) or acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) belongs to the major causes of treatment failure. METHODS Retrospective multicenter analysis of patients diagnosed with AML or MDS who had hematological relapse after allo-HSCT and were treated with azacitidine for this indication. RESULTS Twenty-three patients receiving azacitidine as the first treatment of relapse (Group_1) and 8 patients receiving azacitidine after other treatment of relapse (Group_2) were included. There were 68% males, median age at initiation of azacitidine was 53 years (15-66). Median time to relapse was 3.5 months and 6.3 months in Group_1 and Group_2, respectively; median time from relapse to azacitidine 0.2 and 2.3 months. Azacitidine 75 mg/m2 , days 1-7, was administered in 78% and 75% of patients in Group_1 and Group_2, concomitant DLI in 48% and 50%. With median follow-up of 4.7 and 13.6 months, the median overall survival was 5.9 and 9.5 months. 17% and 37.5% patients proceeded to salvage allo-HSCT, with median OS of 11.6 months and not reached respectively. CONCLUSIONS Azacitidine treatment for hematological relapse is associated with poor outcome; nevertheless, a proportion of patients may benefit from it, including patients receiving subsequent salvage allo-HSCT.

Abstract
INTRODUCTION Screening sinonasal evaluation is routinely performed before allogeneic hematopoietic cell transplantation (allo-HCT), however, data supporting such evaluation is inconsistent. O b j e c t i v e s: Assessment of the utility of screening sinonasal evaluation with computed tomography (CT). METHODS A retrospective analysis of acute leukemia patients who underwent allo-HCT, for whom screening sinonasal CT scans were reevaluated, and for whom Lund-Mackay score (LMS) was calculated. R e s u l t s: Forty-eight patients, the median age at allo-HCT 38 years (18-58), 52% males, were included. 79% had acute myeloid leukemia (AML), 21% acute lymphoblastic leukemia (ALL). Conditioning intensity was myeloablative in 96% of patients, 21% of patients received total body irradiation. 19% of patients had a history of sinusitis before allo-HCT. Screening sinus CT was performed a median of 22 days before allo-HCT. The median LMS was 1 point (0- 10). The severity of sinus abnormalities was: no abnormalities (31%), mild (67%), moderate (2%), severe (0%). Mucosal thickening was the most frequent abnormality (69%). Eleven patients experienced sinusitis after a median of 93 days (11-607) after allo-HCT. 1-year cumulative incidence of sinusitis was 22%. No threshold of LMS and no type of sinus abnormalities were correlated with sinusitis development after allo-HCT. Mild sinus disease at screening did not negatively impact survival in comparison to no sinus disease. C o n c l u s i o n s: Despite the fact, that majority of analyzed patients had either no or mild sinus disease at screening a significant proportion of patients developed sinusitis after allo-HCT. Evaluation of LMS before allo-HCT did not help predict the development of sinusitis after the procedure.

Abstract
AIM To assess the prognostic significance of nucleolar morphological parameters in a large cohort of patients with uveal melanoma. PATIENTS AND METHODS The presence, size and number of nucleoli of cancer cells were assessed in haematoxylin and eosin (HE)-stained slides of 164 formalin-fixed paraffin-embedded primary uveal melanoma tissue specimens. The results were correlated with clinicopathological features and patient survival. RESULTS The presence of macronucleoli and multiple nucleoli significantly correlated with the epithelioid type of uveal melanoma, high mitotic rate, and marked pleomorphism. There was a positive correlation between the presence of macronucleoli as well as the number of nucleoli and the largest tumour basal diameter. The increased nucleolus count in tumour cells positively correlated with primary tumour (pT) staging. The presence of both prominent and multiple nucleoli was associated with significantly reduced overall and disease-free survival. CONCLUSION Histological assessment of nucleolar morphology in routine HE staining would be a helpful low-cost method to obtain reliable prognostic information.

Abstract
BACKGROUND RhoA and its downstream effectors Rho-associated coiled-coil kinases (ROCK) 1 and 2 are central controllers of cytoskeleton dynamics, and therefore influence cell shape, adhesion and migration. Since modulation of these processes holds promise for an effective anticancer strategy, effects of ROCK inhibition have been evaluated in a number of malignancies. MATERIALS AND METHODS Using immunohistochemistry, ROCK1 and ROCK2 expression was semi-quantitatively assessed in 129 patient-derived primary melanomas. RESULTS There was a striking predilection for low melanocytic expression of both kinases in thick, ulcerated and mitogenic tumors, as well as in nodular histological type. ROCK1 and -2 expression in tumor-infiltrating lymphocytes (TILs) was preferentially down-regulated in advanced and aggressive tumors. Moreover, diminished ROCK2 reactivity in melanoma cells and TILs was associated with shorter melanoma-specific and recurrence-free survival. CONCLUSION This is the first analysis of ROCK1 and -2 protein expression in clinical melanoma samples and the results indicated the suppression of ROCK signaling in melanocytes of aggressive and late-stage tumors. Functional models that more accurately represent the clinical setting are necessary to dissect the role of ROCK1 and -2 in melanoma. Additionally, our study indicates that ROCK activity in TILs may be involved in the pathogenesis of cancer, and thus merits further investigations.

Abstract
BACKGROUND Renal impairment (RI) is one of the multiple myeloma (MM)-defining events for initiating therapy. After induction therapy, high-dose chemotherapy followed by autologous peripheral blood stem cell transplant (ASCT) remains the standard of care for transplant-eligible patients with MM. According to the International Myeloma Working Group (IMWG), the organ criterion for kidney damage is defined by a serum creatinine concentration (CrC) > 2 mg/dL or estimated glomerular filtration rate (eGFR) < 40 mL/min. In this long-term study, we evaluated the impact of CrC and eGFR calculated by the Modification of Diet in Renal Disease equation on progression-free and overall survival using a lower threshold than the IMWG criteria. PATIENTS AND METHODS We studied the longitudinal outcomes as measured by progression-free survival and overall survival in 59 transplant-eligible patients with MM: 38 patients with normal renal function and 21 patients with RI defined as a CrC higher than upper limit of normal (≥ 1.1 mg/dL), eGFR < 60 mL/min, treated with ASCT from 1998 to 2004. RESULTS The risk of disease progression and death following ASCT increased by 16.5% (P = .005) and 19% (P < .0009) per 1 mg/dL of CrC, respectively. The thresholds for the association of renal insufficiency and negative outcomes were CrC > 1.4 mg/dL and eGFR < 55mL/min. CONCLUSIONS We observed a negative correlation between minimal renal insufficiency and long-term outcomes. Management of patients with even marginally increased CrC and/or decreased eGFR not fulfilling IMWG RI criteria requires more concentrated effort to reverse even minimal renal insufficiency.

Abstract
Idiopathic scoliosis (IS) etiology remains unclear, but strong genetic background is suggested. Previously reported TIMP2 study indicates an association of genic rs8179090 with IS progression in a Han Chinese population. However, there has been a lack of investigation into intragenic TIMP2 polymorphisms in IS patients. We recruited 100 Caucasian females with IS and 100 controls. Patients were subdivided accordingly to: progression rate, curve severity, joint mobility, and curve pattern. Allele-specific-polymerase chain reaction based on fluorescence resonance energy transfer was applied to evaluate nine TIMP2 polymorphisms. Distribution of genotype and allele frequency in only one polymorphism (rs11658743) differed in case-control study. Four of the polymorphisms (rs2277700, rs11077401, rs2376999, and rs4789934) showed non-equal distributions either in genotype or/and allele distributions in the patients of different progression rates. The rs11077401 was related to curve severity patients distinction and the rs8179090 distinguished patients with different joint mobility level. Two polymorphisms either differed statistically in case of curve patterns subgrouping (rs8068674 and rs8179090) or showed a slight tendency toward significance in the recessive model of allele distributions (rs9916809 and rs8179090). The remaining two polymorphisms (rs2377005, rs11658743) showed no association with either clinical or radiographic IS characteristics. The influence of the G allele of the rs8179090 on the clinical course of IS has not yet been confirmed. We identified four TIMP2 polymorphisms (rs11077401, rs2376999, rs2277700, and rs4789934) that were associated with a higher risk of the progressive IS form. Further genetic association studies based on suggested clinical criteria would be necessary to validate TIMP2 polymorphisms associated with the curve progression. © 2019 Orthopaedic Research Society.

Abstract
The KRAB-ZNF (Krüppel-associated box domain zinc finger) gene family is composed of a large number of highly homologous genes, gene isoforms, and pseudogenes. The proteins encoded by these genes, whose expression is often tissue-specific, act as epigenetic suppressors contributing to the addition of repressive chromatin marks and DNA methylation. Due to its high complexity, the KRAB-ZNF family has not been studied in sufficient detail, and the involvement of its members in carcinogenesis remains mostly unexplored. In this study, we aimed to provide a comprehensive description of cancer-associated KRAB-ZNFs using publicly available The Cancer Genome Atlas pan-cancer datasets. We analyzed 6727 tumor and normal tissue samples from 16 cancer types. Here, we showed that a small but distinctive cluster of 16 KRAB-ZNFs is commonly upregulated across multiple cancer cohorts in comparison to normal samples. We confirmed these observations in the independent panels of lung and breast cancer cell lines and tissues. This upregulation was also observed for most of the KRAB-ZNF splicing variants, whose expression is simultaneously upregulated in tumors compared to normal tissues. Finally, by analyzing the clinicopathological data for breast and lung cancers, we demonstrated that the expression of cancer-associated KRAB-ZNFs correlates with patient survival, tumor histology, and molecular subtyping. Altogether, our study allowed the identification and characterization of KRAB-ZNF factors that may have an essential function in cancer biology and thus potential to become novel oncologic biomarkers and treatment targets.

Abstract
Reliable results of pharmacokinetic and toxicokinetic studies are vital for correct decision making during drug discovery and development. Thus, ensuring high quality of bioanalytical methods is of critical importance. Incurred sample reanalysis (ISR)-one of the tools used to validate a method-is included in the bioanalytical regulatory recommendations. The methodology of this test is well established, but the estimation of the sample size is still commented on and contested. We have applied the hypergeometric distribution to evaluate ISR test passing rates in different clinical study sizes. We have tested both fixed rates of the clinical samples-as currently recommended by FDA and EMA-and a fixed number of ISRs. Our study revealed that the passing rate using the current sample size calculation is related to the clinical study size. However, the passing rate is much less dependent on the clinical study size when a fixed number of ISRs is used. Thus, we suggest using a fixed number of ISRs, e.g., 30 samples, for all studies. We found the hypergeometric distribution to be an adequate model for the assessment of similarities in original and repeated data. This model may be further used to optimize the sample size needed for the ISR test as well as to bridge data from different methods. This paper provides a basis to re-consider current ISR recommendations and implement a more statistically rationalized and risk-controlled approach.

Abstract
BACKGROUND Myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia (CMML), and acute myeloid leukemia (AML) patients, including those treated with azacitidine, are at increased risk for serious infections. The aim of our study was to identify patients with higher infectious risk at the beginning of azacitidine treatment. PATIENTS AND METHODS We performed a retrospective evaluation of 298 MDS/CMML/AML patients and included in the analysis 232 patients who completed the first 3 cycles of azacitidine therapy or developed Grade III/IV infection before completing the third cycle. RESULTS Overall, 143 patients (62%) experienced serious infection, and in 94 patients (41%) infection occurred within the first 3 cycles. The following variables were found to have the most significant effect on the infectious risk in multivariate analysis: red blood cell transfusion dependency (odds ratio [OR], 2.38; 97.5% confidence interval [CI], 1.21-4.79), neutropenia <0.8 × 109/L (OR, 3.03; 97.5% CI, 1.66-5.55), platelet count <50 × 109/L (OR, 2.63; 97.5% CI, 1.42-4.76), albumin level <35 g/dL (OR, 2.04; 97.5% CI, 1.01-4.16), and Eastern Cooperative Oncology Group performance status ≥2 (OR, 2.19; 97.5% CI, 1.40-3.54). Each of these variables is assigned 1 point, and the combined score represents the proposed Azacitidine Infection Risk Model. The infection rate in the first 3 cycles of therapy in lower-risk (0-2 score) and higher-risk (3-5 score) patients was 25% and 73%, respectively. The overall survival was significantly reduced in higher-risk patients compared with the lower-risk cohort (8 vs. 29 months). CONCLUSION We selected a subset with high early risk for serious infection and worse clinical outcome among patients treated with azacitidine.

Abstract
BACKGROUND High-dose chemotherapy followed by autologous peripheral blood stem cell transplantation (auto-PBSCT) remains the mainstay of treatment of eligible patients diagnosed multiple myeloma. The role of clonal plasma cell (CPC) contamination was found as a reason for relapse, but results in terms of survival, progression, and purging were ambiguous. Therefore, the aim of the study was to explore the influence of CPC contamination in the autograft on survival and progression after auto-PBSCT. STUDY DESIGN The study included 59 patients diagnosed and treated for multiple myeloma in 1998-2004. Cells with coexpression of CD38+++CD138++CD56+ and lacking the expression of CD45, CD19, CD10, CD20, and CD23 were considered CPC in flow cytometry. RESULTS The risk of death and progression after auto-PBSCT increased significantly by 10% (P < .021) and 8% (P < .034) per 1 × 106/kg of the CPC number, respectively. For CPC number above 2.96 × 106/kg overall survival achieved clinical significance. Two years after auto-PBSCT, the risk of death was independent of CPC number among the patients who survived (P = .70). Analogous conclusions concerned results of progression-free survival at 1 year after auto-PBSCT. CONCLUSIONS High clonal plasma cell contamination (>2.96 ×1 06/kg; 90th percentile of CPC number) is associated with the worst progression-free survival and overall survival. Therefore purging in vitro might be considered for the patients with the highest CPC contamination. Negative consequences of CPC contamination on the risk of death are observed for only 2 years after auto-PBSCT. Thereafter only those patients who had lower CPC contamination survived.

Abstract
Atypical chronic myeloid leukaemia (aCML) belongs to myelodysplastic/myeloproliferative neoplasms. Because of its rarity and changing diagnostic criteria throughout subsequent classifications, data on aCML are very scarce. Therefore, we at the Polish Adult Leukemia Group performed a nationwide survey on aCML. Eleven biggest Polish centres participated in the study. Altogether, 45 patients were reported, among whom only 18 patients (40%) fulfilled diagnostic criteria. Among misdiagnosed patients, myelodysplastic/myeloproliferative syndrome unclassifiable and chronic myelomonocytic leukaemia were the most frequent diagnoses. Thirteen patients were male, median age 64.6 years (range 40.4-80.9). The median parameters at diagnosis were as follows: white blood cell count 97 × 109 /L (23.8-342) with immature progenitors amounting at 27.5% (12-72), haemoglobin 8.6 g/dL (3.9-14.9), and platelet count 66 × 109 /L (34-833). Cytoreductive treatment was used in all patients, and 2 patients underwent allogeneic hematopoietic stem cell transplantation. The median overall survival was 14.1 months (95% CI, 7.2), with median acute myeloid leukaemia-free survival of 13.3 months (95% CI, 3.6-22.6). Cumulative incidence of acute myeloid leukaemia transformation after 1 year in aCML group was 12.5% (95% CI, 0%-29.6%). To conclude, aCML harbours a poor prognosis. Treatment options are limited, with allogeneic hematopoietic stem cell transplantation being the only curative method at present, although only a minority of patients are transplant eligible. Educational measures are needed to improve the quality of diagnoses.

Abstract
ABSTRACT Morphological variation of the supraorbital region (SR) in human crania has been investigated and its potential sources suggested, along with the importance of the size of the facial skeleton, neurocranium, and orbit for the formation of this region. However, previous studies have not indicated whether facial size exhibits a stronger association with SR robusticity than neurocranial size or sex; moreover, the association between orbital volume and SR robusticity has been analysed only in non-human primate skulls. In this study we investigate whether the size of the facial skeleton, neurocranium, two measures of relative orbital size (orbital volume and estimated orbital aperture area), the relative size of the nasal cavity, and the relative estimated area of the anterior nasal cavity opening are related to SR robusticity; we also examine which of these analysed relationships is strongest, as well as independent of the influence of the other traits, in a geographically diverse modern human cranial sample. The results of Spearman's rank and partial rank correlations (encompassing models including or excluding sex and geographic origin) show a relationship between most of the above-mentioned variables and SR robusticity, with the exception of the estimated relative area of the orbital opening (in the case of the results of Spearman's rank correlations) and the traits of the nasal cavity. Of all the analysed traits, sex appears to be the most important for the formation of SR robusticity and, of two measures of cranial size, neurocranial size was the most significant. The strong relationship between SR robusticity and relative orbital volume was observed in models without the geographic origin factor. The results concerning analysed models suggest the influence of this factor on this relationship; however, to explain this influence, further studies are needed.

Abstract
Cellular reprogramming proceeds in a stepwise pathway initiated by binding and transcription of pluripotency factors followed by genome-wide epigenetic changes. Priming events, such as erasure of DNA methylation and chromatin remodeling determines the success of pluripotency acquisition later. Therefore, growing efforts are made to understand epigenetic regulatory network that makes reprogramming possible and efficient. Here, we analyze the role of transcriptional corepressor TRIM28, involved in heterochromatin formation, during the process of reprogramming of mouse somatic cells into induced pluripotent stem cells (iPS cells). We demonstrate that Trim28 knockdown (Trim28 KD) causes that emerging iPS cells differentiate immediately back into MEFs therefore they fail to yield stable iPS cell colonies. To better comprehend the mechanism of TRIM28 action in reprogramming, we performed a reverse-phase protein array (RPPA) using in excess of 300 different antibodies and compared the proteomic profiles of wild-type and Trim28 KD cells during reprogramming. We revealed the differences in the dynamics of reprogramming of wild-type and Trim28 KD cells. Interestingly, proteomic profile of Trim28 KD cells at the final stage of reprogramming resembled differentiated state rather than maintenance of pluripotency and self-renewal, strongly suggesting spontaneous differentiation of Trim28 KD cells back to their parental cell type. We also observed that action of TRIM28 in reprogramming is accompanied by differential enrichment of proteins involved in cell cycle, adhesion and stemness. Collectively, these results suggest that regulation of epigenetic modifications coordinated by TRIM28 plays a crucial role in reprogramming process.

Abstract
Changes in the morphology of dendritic spines are prominent during learning and in different neurological and neuropsychiatric diseases, including those in which glycogen synthase kinase-3β (GSK-3β) has been implicated. Despite much evidence of the involvement of GSK-3β in functional synaptic plasticity, it is unclear how GSK-3β controls structural synaptic plasticity (i.e., the number and shape of dendritic spines). In the present study, we used two mouse models overexpressing and lacking GSK-3β in neurons to investigate how GSK-3β affects the structural plasticity of dendritic spines. Following visualization of dendritic spines with DiI dye, we found that increasing GSK-3β activity increased the number of thin spines, whereas lacking GSK-3β increased the number of stubby spines in the dentate gyrus. Under conditions of neuronal excitation, increasing GSK-3β activity caused higher activity of extracellularly acting matrix metalloproteinase-9 (MMP-9), and MMP inhibition normalized thin spines in GSK-3β overexpressing mice. Administration of the nonspecific GSK-3β inhibitor lithium in animals with active MMP-9 and animals lacking MMP-9 revealed that GSK-3β and MMP-9 act in concert to control dendritic spine morphology. Altogether, our data demonstrate that the dysregulation of GSK-3β activity has dramatic consequences on dendritic spine morphology, implicating MMP-9 as a mediator of GSK-3β-induced synaptic alterations.

Abstract
BACKGROUND The most frequent cause of kidney allograft loss is chronic allograft injury, often with proteinuria as the clinical feature. Occurrence of proteinuria late after kidney transplantation is associated with worse graft function and patient survival. AIM The aim of the study was to assess plasma and urine matrix metalloproteinases (MMP-2 and MMP-9) and tissue inhibitors of metalloproteinases (TIMP-1 and TIMP-2) in proteinuric renal transplant recipients (RTRs). The factors were determined by enzyme-linked immunosorbent assay in 150 RTRs (51 women and 99 men), aged 49.2 ± 11.5 years, at mean 73.4 ± 41.2 months after kidney transplantation (range: 12 to 240 months). RESULTS Proteinuric RTRs compared with non-proteinuric RTRs had higher median plasma MMP-2 (P = .012), TIMP-1 (P = .0003), and TIMP-2 (P = .0021) concentrations, as well as higher urine MMP-2 (P < .0001) excretion. The presence of proteinuria had no impact on plasma MMP-9 and urine MMP-9, TIMP-1, and TIMP-2. Proteinuria and estimated daily proteinuria (uPr:uCr) correlated positively with plasma MMP-2 (rs = 0.226, P = .0054 and rs = 0.241, P = .003), TIMP-1 (rs = 0.305, P = .00015 and rs = 0.323, P = .000055), TIMP-2 (rs = 0.273, P = .0007 and rs = 0.269, P = .001) and urine MMP-2 (rs = 0.464, P < .0001 and rs = 0.487, P < .0001), respectively. Proteinuric RTRs had impaired graft function with higher median serum creatinine concentrations (1.91 [1.60-2.43] mg/dL versus 1.41 [1.20-1.65] mg/dL, P < .00001) and lower estimated glomerular filtration rate (36 [28-45] mL/min/1.73 m(2) versus 53 [43-61] mL/min/1.73 m(2), P < .00001) than RTRs without proteinuria. CONCLUSIONS Our research revealed that in RTRs, proteinuria was significantly associated with increased concentrations of enzymes involved in extracellular matrix (ECM) degradation: plasma MMP-2, TIMP-1, TIMP-2, and urine MMP-2. Findings strongly emphasize increased plasma TIMPs in proteinuric RTRs that inhibit degradation of ECM by MMPs and favor excessive deposition of ECM proteins.

Abstract
BACKGROUND Advanced age of renal transplant recipients (RTRs) has a negative impact on kidney allograft survival through impaired extracellular matrix degradation by the matrix metalloproteinases/tissue inhibitors of metalloproteinases (MMPs/TIMPs) system. Moreover, older RTRs are at risk of smoldering inflammation, known as inflammaging. AIM The aim of the study was to assess the impact of a RTR's age on plasma and urine concentrations of interleukin 6 (IL-6), chemokine ligand 2 (CCL2), and the MMPs/TIMPs system. MATERIAL AND METHODS One hundred fifty adult RTRs (8.7% ≥ 65 years) and 37 adult healthy volunteers (10.8% ≥ 65 years) were enrolled in the study. The studied factors (IL-6, CCL2, MMP-2, MMP-9, TIMP-1 and TIMP-2) were quantified in plasma and urine with enzyme-linked immunosorbent assay. The Mann-Whitney U test and Spearman's (rs) rank correlation were applied, and differences with a P < .05 were considered statistically significant. RESULTS There was a weak but significant positive correlation between increasing RTR's age and plasma IL-6 (rs = 0.18, P = .028), CCL2 (rs = 0.27, P = .001), and MMP-2 (rs = 0.20, P = .017), as well as urine CCL2 (rs = 0.16, P = 0.050) and TIMP-1 (rs = 0.20, P = .014) concentrations. CONCLUSIONS Advancing age of RTRs correlates with increasing plasma IL-6 and CCL2 concentrations, reflecting smoldering inflammation (known as inflammaging) and alterations in MMPs/TIMPs profiles, especially with increased plasma MMP-2 and urine TIMP-1 concentrations.

Abstract
Hypertension is a multifactorial disease caused by environmental, metabolic and genetic factors, but little is currently known on the complex interplay between these factors and blood pressure. The aim of the present study was to assess the potential impact of obesity, and angiotensin-converting enzyme (ACE) I/D polymorphism and endothelial nitric oxide synthase gene (NOS3) 4a/4b, G894T and -T786C variants on the essential hypertension. The study group consisted of 1,027 Caucasian adults of Polish nationality (45.5 ± 13.6 years old), of which 401 met the criteria for hypertension. Body weight, height and blood pressure were measured and data on self-reported smoking status were collected. Fasting blood glucose, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides were determined by standard procedures. The ACE I/D polymorphism and three polymorphisms in NOS3 gene (4a/4b, G894T, -T786C) were detected by the PCR method. Multivariable logistic regression demonstrated that age above 45 years, diabetes, dyslipidemia, smoking and male sex are important risk factors for hypertension and no significant influence of variants in ACE and NOS3 genes on this risk was recognized. Obese subjects had a 3.27-times higher risk (OR = 3.27, 95% CI: 2.37 - 4.52) of hypertension than non-obese, and in obese the NOS3 894T allele was associated with 1.37 fold higher risk of hypertension (P = 0.031). The distribution of NOS3 G894T genotypes supported the co-dominant (OR = 1.35, P = 0.034, Pfit = 0.435) or recessive (OR = 2.00, P = 0.046, Pfit = 0.286), but not dominant model of inheritance (P = 0.100). The study indicates that in obese NOS3 G894T polymorphism may enhance hypertension risk. However, in the presence of such strong risk factors as age, diabetes and smoking, the impact of this genetic variant seems to be attenuated. Further studies are needed to reveal the usefulness of G894T polymorphism in hypertension risk assessment in obese.

Abstract
Although some hypotheses that attempt to explain the variation in supraorbital region morphology in modern humans have been proposed, this issue is still not well understood. In this study, the craniofacial size and spatial models were tested using a sample of modern human crania from geographically diverse populations, and the co-occurrence of the degrees of glabella (GL) and superciliary arch (ST) expression were analyzed. The two supraorbital structures were examined by visual assessment, and eight quantitative variables were included in the three-way ANOVA, canonical variates analysis and partial rank correlation. The influences of sex and the region of origin of the cranial samples on the relationships between the examined variables and the degrees of supraorbital structures expression were also considered. The results only partially supported the craniofacial size and spatial models and suggested that GL and ST experienced separate influences during development. In the sample of all crania, the neurocranial size more strongly influenced the morphological variation of the ST than of the GL, and sex influenced both of these structures the most. The results suggest that sex may be the main factor (having an influence independent of the other traits) on the morphological variation of the GL and ST.

Abstract
Maize, despite being thermophyllic due to its tropical origin, demonstrates high intraspecific diversity in cold-tolerance. To search for molecular mechanisms of this diversity, transcriptomic response to cold was studied in two inbred lines of contrasting cold-tolerance. Microarray analysis was followed by extensive statistical elaboration of data, literature data mining, and gene ontology-based classification. The lines used had been bred earlier specifically for determination of QTLs for cold-performance of photosynthesis. This allowed direct comparison of present transcriptomic data with the earlier QTL mapping results. Cold-treated (14 h at 8/6 °C) maize seedlings of cold-tolerant ETH-DH7 and cold-sensitive ETH-DL3 lines at V3 stage showed strong, consistent response of the third leaf transcriptome: several thousand probes showed similar, statistically significant change in both lines, while only tens responded differently in the two lines. The most striking difference between the responses of the two lines to cold was the induction of expression of ca. twenty genes encoding membrane/cell wall proteins exclusively in the cold-tolerant ETH-DH7 line. The common response comprised mainly repression of numerous genes related to photosynthesis and induction of genes related to basic biological activity: transcription, regulation of gene expression, protein phosphorylation, cell wall organization. Among the genes showing differential response, several were close to the QTL regions identified in earlier studies with the same inbred lines and associated with biometrical, physiological or biochemical parameters. These transcripts, including two apparently non-protein-coding ones, are particularly attractive candidates for future studies on mechanisms determining divergent cold-tolerance of inbred maize lines.

Abstract
The differentiation-inducing potential of side-chain modified analogs of vitamins D, compared to the reference compound, 1,25-dihydroxyvitamin D3, was studied in blast cells from patients with acute myeloid leukemia and in cell lines. Analogs PRI-1906 and PRI-1907 showed increased cell-differentiation activities, PRI-1907 even at a very low concentration. Our study revealed a high variability of individual patients' blasts in their susceptibility to vitamin D analogs. The blasts of the patients with normal karyotype and with mutated NPM1 reacted to analogs with stronger differentiation than the blasts of the remaining patients, while the blasts with mutated FLT3 receptor reacted with weaker differentiation than the remaining blasts.

Abstract
Chronic allograft injury (CAI) is the most frequent cause of progressive kidney allograft impairment and eventual loss, which is due to interstitial fibrosis and tubular atrophy (IF/TA). Mechanisms of CAI are not fully understood. Chemokines, cytokines, metalloproteinases (MMPs), and tissue inhibitors of metalloproteinases (TIMPs) play roles in fibrosis development. The aims of this study were to evaluate plasma and urine TIMPs (TIMP-1 and TIMP-2), MMPs (MMP-2 and MMP-9), proinflammatory interleukin-6 (IL-6), chemokine (C-C motif) ligand 2 (CCL2 chemokines previously known as monocyte chemoattractant protein-1 [MCP-1]) among 150 recipients beyond 1 year post-renal transplantations and to explore the usefulness of these potential biomarkers of ongoing allograft injury. Renal transplant recipients compared with healthy volunteers (control group) showed significantly increased plasma and urine IL-6, MMP-9, TIMP-1, and TIMP-2, as well as lower plasma MMP-2 and urine CCL2 concentrations. Compared with recipients showing good function those with impairments displayed higher plasma TIMP-1 (P < .001) and TIMP-2 (P = .003) concentrations. The recipient estimated glomerular filtration rate (eGFR) values negatively correlated with plasma TIMP-1 and TIMP-2 levels (r = -0.43; P < .0001 and rs = -0.42; P < .0001, respectively) and with urine IL-6 excretion (rs = -0.33; P < .0001). Multivariate and receiver operating characteristic (ROC) analyses showed TIMP-1 plasma level assessments to be useful estimates of allograft injury.
