Abstract
Reliable biomarkers are needed to avoid diagnostic delay and its devastating effects in patients with primary central nervous system (CNS) lymphoma (PCNSL). We analysed the discriminating sensitivity and specificity of myeloid differentiation primary response (88) (MYD88) L265P mutation (mut-MYD88) and interleukin-10 (IL-10) in cerebrospinal fluid (CSF) of both patients with newly diagnosed (n = 36) and relapsed (n = 27) PCNSL and 162 controls (118 CNS disorders and 44 extra-CNS lymphomas). The concordance of MYD88 mutational status between tumour tissue and CSF sample and the source of ILs in PCNSL tissues were also investigated. Mut-MYD88 was assessed by TaqMan-based polymerase chain reaction. IL-6 and IL-10 messenger RNA (mRNA) was assessed on PCNSL biopsies using RNAscope technology. IL levels in CSF were assessed by enzyme-linked immunosorbent assay. Mut-MYD88 was detected in 15/17 (88%) PCNSL biopsies, with an 82% concordance in paired tissue-CSF samples. IL-10 mRNA was detected in lymphomatous B cells in most PCNSL; expression of IL-6 transcripts was negligible. In CSF samples, mut-MYD88 and high IL-10 levels were detected, respectively, in 72% and 88% of patients with newly diagnosed PCNSL and in 1% of controls; conversely, IL-6 showed a low discriminating sensitivity and specificity. Combined analysis of MYD88 and IL-10 exhibits a sensitivity and specificity to distinguish PCNSL of 94% and 98% respectively. Similar figures were recorded in patients with relapsed PCNSL. In conclusion, high detection rates of mut-MYD88 and IL-10 in CSF reflect, respectively, the MYD88 mutational status and synthesis of this IL in PCNSL tissue. These biomarkers exhibit a very high sensitivity and specificity in detecting PCNSL both at initial diagnosis and relapse. Implications of these findings in patients with lesions unsuitable for biopsy deserve to be investigated.

Abstract
In this work we present the case of SARS-CoV-2 infection in a 1.5-year-old boy affected by severe Wiskott-Aldrich Syndrome with previous history of autoinflammatory disease, occurring 5 months after treatment with gene therapy. Before SARS-CoV-2 infection, the patient had obtained engraftment of gene corrected cells, resulting in WASP expression restoration and early immune reconstitution. The patient produced specific immunoglobulins to SARS-CoV-2 at high titer with neutralizing capacity and experienced a mild course of infection, with limited inflammatory complications, despite pre-gene therapy clinical phenotype.

Abstract
Neutrophil gelatinase-associated lipocalin (NGAL) is a protein of lipocalin family highly expressed in various pathologic states and is an early biomarker of acute kidney injury in cardiac surgery. We performed an observational study to evaluate the role of NGAL in predicting postoperative intensive care stay in high-risk patients undergoing cardiac surgery. We enrolled 27 consecutive patients who underwent high-risk cardiac surgery with cardiopulmonary bypass. Urinary NGAL (uNGAL) was measured before surgery, at intensive care unit (ICU) arrival and 24 h later. Univariate and multivariate predictors of ICU stay were performed. uNGAL was 18.0 (8.7-28.1) ng/mL at baseline, 10.7 (4.35-36.0) ng/mL at ICU arrival and 29.6 (9.65-29.5) 24 h later. The predictors of prolonged ICU stay at the multivariate analysis were body mass index (BMI), uNGAL 24 h after surgery, and aortic cross-clamp time. The predictors of high uNGAL levels 24 h after at a multivariate analysis were preoperative uNGAL and logistic European System for Cardiac Operative Risk Evaluation. At a multivariate analysis the only independent predictors of prolonged ICU stay were BMI, uNGAL 24 h after surgery and aortic cross-clamp time.

Abstract
INTRODUCTION There is currently neither a clinically useful, reliable and inexpensive assay to measure circulating levels of free testosterone (T) in the range observed in women, nor is there agreement on the serum free T threshold defining hypoandrogenism that is associated with female-impaired sexual function. AIM Following the Clinical and Laboratory Standards Institute guidelines, we generated clinically applicable ranges for circulating androgens during specific phases of the menstrual cycle in a convenience sample of 120 reproductive-aged, regularly cycling healthy European Caucasian women with self-reported normal sexual function. METHODS All participants were asked to complete a semistructured interview and fill out a set of validated questionnaires, including the Female Sexual Function Index, the Female Sexual Distress Scale, and the 21-item Beck's Inventory for Depression. Between 8 am and 10 am, a venous blood sample was drawn from each participant during the midfollicular (day 5 to 8), the ovulatory (day 13 to 15), and the midluteal phase (day 19 to 22) of the same menstrual cycle. MAIN OUTCOME MEASURES Serum levels of total and free testosterone, Delta(4)-androstenedione, dehydroepiandrosterone sulphate and sex hormone-binding globulin during the midfollicular, ovulatory and midluteal phase of the same menstrual cycle. RESULTS Total and free T levels showed significant fluctuations, peaking during the ovulatory phase. No significant variation during the menstrual cycle were observed for Delta(4)-androstenedione and dehydroepiandrosterone sulphate. Despite the careful selection of participants that yielded an homogeneous group of women without sexual disorders, we observed a wide range of distribution for each of the circulating androgens measured in this study. CONCLUSIONS This report provides clinically applicable ranges for androgens throughout the menstrual cycle in reproductive-aged, regularly cycling, young healthy Caucasian European women with self-reported normal sexual function.

Abstract
The urokinase plasminogen activator receptor (uPAR) fragments D1 and D2D3 are often found in biological fluids from normal individuals and patients of cancer and other diseases. The D2D3 fragment may possess chemotactic activity depending on its N-terminal sequence. We have developed a sensitive and specific immunoassay for the chemotactic form of D2D3 and show that its level can be measured with high specificity and sensitivity in human serum and urine. Synthetic peptides (residues 84-92) derived from the linker region between domains 1 and 2 of uPAR were used as immunogens to generate mouse monoclonal antibodies. Recombinant soluble uPAR (D1D2D3(1-277)) was used to immunize rabbits to obtain polyclonal antibodies. A sandwich-type immunofluorimetric assay was developed with these antibodies. The assay specifically measures D2D3 containing the 84-88 residues, has a detection limit of 0.25 ng/ml and shows no cross-reactivity with D2D3(93-274). The assay is linear at 0-30 ng/ml, with an intra-assay CV of 10% (n=20), inter-assay CV of 15% (n=9) and a recovery of D2D3(84-274) added to urine samples of between 94% and 105%. A statistically significant difference level of D2D3(84-274) was found in two groups of tumor patients versus healthy volunteers (p<or=0.009 in colorectal carcinomas and p<or=0.036 in prostatic carcinomas). For the first time, monoclonal antibodies, detecting the chemotactic form of uPAR, D2D3(84-274), have been produced. The immunofluorimetric assay will quantitate uPAR chemotactic fragments in biological samples, including serum and urine, and evaluate their diagnostic or prognostic potential in clinical studies.

Abstract
Circulating levels of the neuro-hypophysial nonapeptide oxytocin increase during sexual arousal and orgasm in both men and women. A few studies have evaluated the effect of the menstrual cycle on plasma oxytocin in normally cycling, sexually active, healthy fertile women using or not using contraceptive pills. In 20 ovulating women and 10 women taking an oral contraceptive (group 1 and group 2, respectively), sexual function, hormonal profile, and plasma oxytocin (OT) were evaluated throughout the menstrual cycle. In group 1, plasma OT was significantly lower during the luteal phase in comparison with both the follicular and ovulatory phases. Plasma oxytocin was significantly correlated with the lubrication domain of the Female Sexual Function Index (FSFI) during the luteal phase and showed a trend towards statistical significance during the follicular phase. In group 2, plasma OT did not show any significant fluctuation throughout the menstrual cycle, even though a significant correlation was evident with both the arousal and the lubrication domain of the FSFI during the assumption of the contraceptive pill. These findings suggest that plasma OT fluctuates throughout the menstrual cycle in normally cycling healthy fertile women with adequate sexual activity but not taking any oral contraceptive pill. Moreover, plasma OT levels significantly relates to the genital lubrication in both women taking and not taking oral contraceptive pill apparently confirming its role in peripheral activation of sexual function.

Abstract
Semen sample analysis is routinely performed by microscopical evaluation and manual techniques by laboratory operators; the analysis is affected by a wide imprecision related to variability among observers, influencing its clinical validity. Our aim was to automate sperm analysis with the use of flow cytometry for evaluation of cell counts and typing and with the use of a new membrane-permeant nucleic acid stain for evaluation of sperm viability. Statistical analysis of the comparison between manual and automated methods for sperm counts was performed by the Bland and Altman method; the mean difference was 0.243 x 10(6) sperms/ mL. The precision of the flow cytometric analysis was evaluated with whole sperm; the between-run CV was 7.5% and the within-run CV was 2.5%. Data observed suggest that flow cytometric sperm analysis, with high precision and accuracy and low costs, can be proposed for routine use in clinical laboratories.

Abstract
The study was designed to assess the sensitivity of three commercial assays (which differ in methodology, standard and antibodies) for osteocalcin, used for detecting changes in osteocalcin secretion induced by calcitriol (1,25-dihydroxycholecalciferol) in vivo and in vitro. Osteocalcin levels were determined in serum samples of 10 osteoporotic women after short term calcitriol treatment, and in the culture medium of human osteoblast-like cells (n = 22) after 48 h calcitriol exposure. All assays displayed similar sensitivity in detecting osteocalcin production in vivo after a 1 microgram daily dose of calcitriol. A novel IRMA (CIS), claimed to detect intact osteocalcin, showed higher osteocalcin values than the other assays, and in vitro showed the best sensitivity; it provides an appropriate index of the osteocalcin synthetic activity of cultured human osteoblasts.

Abstract
OBJECTIVE To evaluate the effects of a coculture with human endometrial cells on the function of spermatozoa from samples obtained from infertile couples. DESIGN In a prospective study, human spermatozoa selected by swim-up from fresh samples were cultured on human endometrial feeder layers. Thereafter, their viability, motility, acrosome integrity, and ability to penetrate zona-free hamster oocytes were evaluated. Spermatozoa from the same samples incubated under the same conditions but in the absence of endometrial cells, as well as in the medium previously spent for cell culture, were used as controls. SETTING Andrology Laboratory of the Infertility Center of San Raffaele Hospital. PATIENTS Spermatozoa were obtained from 17 infertile men attending the Infertility Center at our hospital. RESULTS Spermatozoa incubated in the presence of endometrial cell feeder layers did not differ from controls with regard to their viability or motility. Conversely, the percent spontaneous acrosome reactions after 18 hours of incubation was significantly higher for spermatozoa cocultured (19.7 +/- 2.2 versus 11.2 +/- 1.9; mean +/- SE). The mean number of spermatozoa penetrating hamster oocytes was also significantly improved (1.24 +/- 0.3 versus 0.68 +/- 0.24). This effect did not seem to be solely due to the secretion of soluble factors by endometrial cells in the medium, in that spermatozoa incubated in the medium spent for endometrial cell culture had a similar acrosome reaction percentage but a lower rate of hamster egg penetration. CONCLUSIONS The coculture with human endometrial cells appeared to be beneficial for improving the sperm function. This effect partially may be due to the secretion of steroids in the medium, which increases the quota of spontaneous acrosome reaction and in part due to the direct contact of cells with spermatozoa, maybe for the detoxification of the medium or the release of trophic factors. Coculture might be a promising approach to preparing spermatozoa for assisted fertilization in cases of subfertile males.

Abstract
The purpose of this study was to verify if a decreased inhibition of PTH secretion (abnormal suppressibility) in response to physiological increment of plasma calcium is present in patients with osteoporosis. The plasma concentration curve of intact PTH 1-84 following an oral calcium load (Pak) has been calculated in a selected population of 38 osteopenic patients (16 males and 22 females) and in a control group of 9 young healthy adults. All the patients included in this study a) had no past or present diseases and medications of potential influence on calcium homeostasis, b) showed a maximal calcemic response to the oral calcium load equal to that of the control group. PTH suppressibility was significantly smaller in the osteoporotic patients (-42% in males and -32% in females) than in the control group (-76%). This abnormal suppressibility of PTH is independent on sex and, in the females, also on postmenopausal estrogen deficiency. These results support the hypothesis that osteoporosis is associated to an altered secretory response of parathyroid glands maybe due to reduced sensitivity of the parathyroid cells to extracellular calcium.

Abstract
The oral calcium load test, originally proposed for evaluating the intestinal calcium absorption and the renal calcium leak triggers some endocrine and metabolic responses addressed to correct the "calcemic error" induced by the load. Besides the increased plasma calcium there are: plasma PTH drop, increment in the urinary calcium excretion and in the threshold of tubular phosphate reabsorption. These responses have been measured and reciprocally correlated in 9 young adults at different times after the oral calcium load. The responses can be assessed with high precision in clinical practice and are in agreement with the known physiological models. The oral calcium load test is proposed as a tool for studying in the osteopenic population in the individual's capacity of correcting the calcemic error induced by the load.

Abstract
We studied total testosterone, sex hormone binding globulin, and free testosterone in four males presenting an electrophoretically slow-moving genetic variant of albumin, the alloalbumin Catania. Free testosterone levels were lower in these cases, found in a year of observation, than those expected for the ages. This finding, which is not related to any disease and constantly not recognized in other males with various genetic variants, should induce consideration of a probable difference of the genetic variant in hormone binding.

Abstract
In a patient with motor neuron disease and benign IgMk monoclonal gammopathy, the M protein reacted with the glycolipids GM1, GD1b, and asialo GM1 and, by immunoblot, with some high-molecular-weight neural-specific glycoproteins. The main reactive bands had an approximate molecular weight of 250 and 400 kd, were most concentrated in the spinal cord, and were also bound by the lectin peanut agglutinin. The presence of the Ga1(beta 1-3)Ga1NAc epitope on these neural-specific glycoproteins may help to explain the selective neurological impairment of the patient.

Abstract
Twenty-seven patients with neuropathy and IgM monoclonal gammopathy were tested for antigen specificity of the M-protein and for anti-myelin-associated glycoprotein (MAG) IgM levels by immunoblot. In 16 patients (59.2%) the M-protein reacted with MAG and with cross-reactive glycoconjugates. Anti-MAG IgM titers in these patients ranged between 1:12,800 and 1:100,000. A fainter IgM reactivity with MAG and related glycoconjugates was detected in 3 additional patients with neuropathy, but also in 8 of 24 patients with IgM M-protein without neuropathy (33.3%). This reactivity was not due to the M-protein and corresponded to antibody titers of 1:400 or less in all but 1 patient with a titer of 1:3,200. Low titers of anti-MAG IgM (1:200 or less) were also detected in 17 of 101 control patients without IgM M-proteins (16.8%), while 1 patient with neuropathy of unknown cause had anti-MAG IgMK titers of 1:25,600. In 1 patient with neuropathy and IgM M-protein that was not anti-MAG, the M-protein bound to other antigens in nerve, while in 6, other possible causes or mechanisms for the neuropathy were found. In this study, high titers of anti-MAG IgM antibodies were always associated with neuropathy. The presence of low levels of anti-MAG IgM in a significant proportion of controls suggests that monoclonal expansion of naturally occurring B-cell clones secreting anti-MAG IgM may be responsible for the high incidence of this antigen specificity of the M-protein.

Abstract
We studied the CSF and sera from 16 patients with MS to detect IgG antibody activity against normal CNS myelin and some of its proteic and lipidic components. IgG binding to a protein band of the same MW of myelin basic protein was detected by "immunoblot" in the sera and/or CSF of 25% of patients with MS and in none of the controls with OND. No IgG antibody reactivity against other components of CNS myelin was detectable in patients with MS, and immunoabsorption of the CSF of MS patients with CNS myelin did not modify the oligoclonal prophile of CSF IgG. Anti-myelin antibodies do not seem to represent the bulk of oligoclonal IgG in MS patients.
