Abstract
BACKGROUND Optimal consolidation for young patilents with relapsed/refractory (R/R) follicular lymphoma (FL) remains uncertain in the rituximab era, with an unclear benefit of autologous stem cell transplantation (ASCT). The multicenter, randomized, phase III FLAZ12 (NCT01827605) trial compared anti-CD20 radioimmunotherapy (RIT) with ASCT as consolidation after chemoimmunotherapy, both followed by rituximab maintenance. PATIENTS AND METHODS Patients (age 18-65 years) with R/R FL and without significant comorbidities were enrolled and treated with three courses of conventional, investigator-chosen chemoimmunotherapies. Those experiencing at least a partial response were randomized 1 : 1 to ASCT or RIT before CD34+ collection, and all received postconsolidation rituximab maintenance. Progression-free survival (PFS) was the primary endpoint. The target sample size was 210 (105/group). RESULTS Between August 2012 and September 2019, of 164 screened patients, 159 were enrolled [median age 57 (interquartile range 49-62) years, 55% male, 57% stage IV, 20% bulky disease]. The study was closed prematurely because of low accrual. Data were analyzed on 8 June 2023, on an intention-to-treat basis, with a 77-month median follow-up from enrollment. Of the 141 patients (89%), 70 were randomized to ASCT and 71 to RIT. The estimated 3-year PFS in both groups was 62% (hazard ratio 1.11, 95% confidence interval 0.69-1.80, P = 0.6662). The 3-year overall survival also was similar between the two groups. Rates of grade ≥3 hematological toxicity were 94% with ASCT versus 46% with RIT (P < 0.001), and grade ≥3 neutropenia occurred in 94% versus 41%, respectively (P < 0.001). Second cancers occurred in nine patients after ASCT and three after radioimmunotherapy (P = 0.189). CONCLUSIONS Even if prematurely discontinued, our study did not demonstrate the superiority of ASCT versus RIT. ASCT was more toxic and demanding for patients and health services. Both strategies yielded similar, favorable long-term outcomes, suggesting that consolidation programs milder than ASCT require further investigation in R/R FL.

Abstract
PURPOSE The main aim of the study is to assess clinical and functional outcomes of arthroscopic outside-in repair of isolated radial tears of the midbody of lateral meniscus in professional athletes and to evaluate the return to the sport activity after surgery. METHODS A retrospective data collection on professional athletes with isolated complete lesion of the midbody of lateral meniscus, treated with arthroscopic outside-in repair was carried out. Outcome measures included functional assessment, Limb Symmetry Index (LSI) and Hamstring Quadriceps Ratio (HQR) and Lysholm score collected before surgery and at 4-month follow-up. Data on return to sport practice and re-injury were also retrieved. RESULTS Fourteen patients satisfied the selection criteria. Full return to professional sport activity (Tegner 10) was registered in the 86% of the cohort at 4 months after the surgery. Functional testing of the athletes showed a return of the LSI and HQR to the pre-surgical condition, demonstrating a full recovery of the functional ability and muscle strength. Similarly, clinical evaluation through Lysholm score showed an improvement, reaching an average of 97.7 points at 4 months follow-up. CONCLUSION A good functional recovery and a high rate of return to play has been observed in a population of professional athletes, at 4 months after outside-in repair.

Abstract
We report herein a multicentre retrospective analysis of 192 consecutive patients with symptomatic refractory/relapsed multiple myeloma (RRMM) treated with daratumumab in combination with bortezomib or lenalidomide as salvage therapy at 9 haematological centres in Puglia. Choice of both regimens was based on previous treatment and/or physicians' preference. Considering the under-representation of older patients (very old patient ≥ 80 years) in clinical trials and the prognostic and predictive importance and value of frailty status, here, we further characterised the patient cohort by age. The overall response rate (ORR) was generally lower than what was previously reported in the CASTOR (ORR 72.6% vs 85%) and POLLUX (ORR 86.5% vs 93%) trials. The lower ORR in our analysis compared to the CASTOR and POLLUX trials could be related to a less selected population. Similarly, amongst very old patients, the ORR was encouraging: ORR to treatment with DVd (daratumumab + bortezomib + dexamethasone) was 66.7%, and ORR to treatment with DRd (daratumumab + lenalidomide + dexamethasone) was 92.3%. Median TTP (time to progression) was 10.8 months (1-year TTP: 44.7%; 2-year TTP: 25.3%) in the DVd group; median TTP was not reached in the DRd group (1-year TTP: 82.7%; 2-year TTP: 71.4%). Median OS (overall survival) was not reached either in the DRd group (1-year OS: 85.9%; 2-year OS: 73.7%) or the DVd group (1-year OS: 70.2%; 2-year OS: 58.9%).

Abstract
Abstract
Study question
Could EVs secreted by aneuploid embryos a) serve for development of RNA biomarkers for PGT-A and b) elicit a relevant transcriptomic response in decidualised ESCs?
Summary answer
Aneuploid embryo EVs a) contain PPM1J, LINC00561, ANKRD34C and TMED10 in differential abundance from euploid EVs and b) induce up-regulation of MUC1 in decidualised ESCs.
What is known already
Embryo aneuploidy accounts for approximately 50% of all recurrent implantation failures in women >35 years old. PGT-A identifies euploid embryos to increase implantation probability but the technology is controversial as it requires an invasive embryo biopsy with an elusive long-term biosafety. The development of non-invasive methods to screen out aneuploid embryos is paramount. It is also critical to decode the embryo-endometrial dialog underlying implantation failure. We have previously reported that IVF embryos secrete EVs that can be internalised by ESCs, conceptualising that successful implantation to the endometrium is facilitated by EVs, which may additionally serve as biomarkers of ploidy status.
Study design, size, duration
Embryos destined for biopsy on days 5-7 for PGT-A were grown under standard conditions. Spent media (30μl) were collected from euploid (n = 175) and aneuploid embryos (n = 145) at both cleavage (days 1-3) and blastocyst (days 3-5) stage. Media samples from n = 35 cleavage embryos were pooled in order to obtain five euploid and four aneuploidy pools. Blastocyst media were pooled to create one euploid and one aneuploid pool. ESCs were obtained from five women undergoing diagnostic laparoscopy.
Participants/materials, setting, methods
The study was realised at a research hospital. EVs were isolated from euploid and aneuploid Day3 pools with differential ultracentrifugation and EV-RNA sequencing was performed following the SMARTer Stranded Total RNA-Seq approach. ESCs were decidualised (E2:10nM, P4:1uM, cAMP:0.5 mM twice every 48 hours) and treated for 24 hours with 50 ng/ml euploid or aneuploid EVs extracted from blastocyst media. RNA sequencing was performed on ESCs following the Truseq RNAseq protocol.
Main results and the role of chance
Aneuploid cleavage stage embryos (n = 4) secreted EVs that were less abundant in RNA fragments originating from the genes PPM1J (log2fc=-5.13, p = 0.011), LINC00561 (log2fc=-7.87, p = 0.010) and ANKRD34C (log2fc=-7.30, p = 0.017) and more abundant in TMED10 (log2fc=1.63 p = 0.025) compared to EVs (n = 5) from euploid embryos. Decidualisation per se induced downregulation of MUC1 (log2FC=-0.54, p = 0.0028) in ESCs as prerequisite for the establishment of receptive endometrium. The expression of MUC1 transcript in decidualised ESCs was significantly increased following treatment with aneuploid compared to euploid embryo-secreted EVs (log2FC=0.85, p = 0.0201).
Limitations, reasons for caution
The findings of the study may require validation utilising a second cohort of EVs samples.
Wider implications of the findings
This discovery that the RNA cargo of EVs secreted from aneuploid cleavage stage embryos is diverse from that of euploid embryos potentiates the development of non-invasive methodology for PGT-A. The upregulation of MUC1 in decidualised ESCs following aneuploid embryo EV treatment proposes a new mechanism underlying implantation failure.

Abstract
Study question
How do fertility clinics’ websites of the UK, Belgium and Spain present the medical risks of egg donation and incentives?
Summary answer
Spanish and UK websites typically included more incentives to recruit egg donors compared to the Belgian websites. OHSS was overall the most discussed risk.
What is known already
People commonly turn to the internet for initial information. Primary presentations of information of a subject co-determine how an individual interprets the topic and thus influence later decisions. Considering the growing demand and clinics’ dependency on egg donors, some scholars have expressed concerns that clinics might (initially) misrepresent risks to recruit more egg donors. Offering appealing incentives may also encourage potential donors to dismiss possible risks and side-effects.
Therefore, it is important to see how incentives (both monetary and non-monetary rewards) and risks are presented on the websites of fertility clinics, the first source of information for egg donors.
Study design, size, duration
This study is part of the EDNA-project, a multi-phased comparative study (2017-2021), that aims to explore the social, political, economic and moral configuration of egg donation in the United Kingdom, Belgium and Spain. In this study, we only focused on the medical risks of egg donation and incentives presented on the fertility clinics’ websites of the three countries.
Participants/materials, setting, methods
We analysed the websites of all Belgian fertility clinics (n = 18), and a maximum variation sample in the UK (n = 21) and Spain (n = 23). The sampling was based on the geographical location of the clinic, size/number of cycles performed each year, the clinic’s status (independent or part of a larger clinical group) and whether the clinic was public or privately funded in the UK. Frame analysis and content analysis were used for analysis in Nvivo12.
Main results and the role of chance
No misrepresentation of risks was found. There was an extensive variety in the representation of risks. There were differences between the websites of the three countries (e.g. the risks of having acne was only discussed on Spanish websites), but also remarkable differences within the websites of a particular country (of the 40 risks, 13 were one-off mentions, each found on a single website). A description of a risk was generally accompanied by a minimization or normalization of the risk, or a statement about the fertility clinic’s excellent care for their egg donors. These three approaches were often combined.
Our analysis differentiated between incentives (i.e. external rewards) and emotional appeals. An appeal to emotions (e.g. empathy) can also motivate behavioural action (e.g. donation) but was not considered as an incentive since there is no external reward.
While Belgian websites used almost no incentives, Spanish and UK websites used gratitude and a rewarding experience as incentives. However, only Spanish websites used free medical tests as incentives, while UK websites were the only ones that used discounts received with egg sharing as an incentive. All countries’ websites used emotional appeals by enticing feelings of empathy for the recipients.
Limitations, reasons for caution
Not all UK and Spanish fertility clinics’ websites were analysed. However, our international team of researchers applied a maximum variation sampling strategy. This generated samples of clinics per country that were as diversified as possible.
Wider implications of the findings
The study shows that incentives are more often used on the UK and Spanish websites than on the Belgian websites. All three countries’ websites used emotional appeals. It should be studied how effective these incentives and emotional appeals are, and if there is a correlation with the potential donors’ risk-perceptions.

Aneuploid cleavage stage embryos (n = 4) secreted EVs that were less abundant in RNA fragments originating from the genes PPM1J (log2fc=–5.13, p = 0.011), LINC00561 (log2fc=–7.87, p = 0.010) and ANKRD34C (log2fc=–7.30, p = 0.017) and more abundant in TMED10 (log2fc=1.63 p = 0.025) compared to EVs (n = 5) from euploid embryos. Decidualisation per se induced downregulation of MUC1 (log2FC=–0.54, p = 0.0028) in ESCs as prerequisite for the establishment of receptive endometrium. The expression of MUC1 transcript in decidualised ESCs was significantly increased following treatment with aneuploid compared to euploid embryo-secreted EVs (log2FC=0.85, p = 0.0201).
Limitations, reasons for caution
The findings of the study may require validation utilising a second cohort of EVs samples.
Wider implications of the findings: This discovery that the RNA cargo of EVs secreted from aneuploid cleavage stage embryos is diverse from that of euploid embryos potentiates the development of non-invasive methodology for PGT-A. The upregulation of MUC1 in decidualised ESCs following aneuploid embryo EV treatment proposes a new mechanism underlying implantation failure.

Abstract
PURPOSE Flexible flatfoot (FFF) is a widespread condition in juvenile patients. If symptomatic, FFF can require surgical treatment. The calcaneo-stop procedure has shown excellent clinical and radiographic outcomes and low rates of complications. The aim of the present study was to assess the sport practice of young athletes affected by FFF having undergone the calcaneo-stop procedure. METHODS Between 2008 and 2016, 68 sport practitioners were bilaterally treated by the calcaneo-stop procedure, for a total of 136 FFF cases. Clinical evaluation, including the American Orthopedic Foot and Ankle Score (AOFAS), the Yoo et al score and The Foot & Ankle Disability Index (FADI) and FADI Sport scores were assessed. Radiographic evaluation was based on measurement of talar declination, Costa-Bertani's angle and calcaneal pitch. RESULTS Mean follow-up was 57.6 months (sd 16.8). The AOFAS score mean increased from 79.3 (sd 5.7) to 97.3 (sd 4.5) three years after surgery. The Yoo score improved from 3.1 (sd 1.0) preoperatively to 11.7 (sd 0.6) three years after surgery. The FADI Sport subscale mean improved from 74.1 (sd 10.4) preoperatively to 95.9 (sd 4.9) three years after surgery.Costa-Bertani's angle decreased from 156.1° (sd 4.2°) to 135.8° (sd 7.3°) at three years postoperatively; mean talar declination angle decreased from 44.2° (sd 6.3°) to 30.6° (sd 3.2°) at three years postoperatively and mean calcaneal pitch increased from 12.6° (sd 2.3°) to 16.3° (sd 1.3°) at three years postoperatively. CONCLUSION Adolescent patients who underwent the calcaneo-stop procedure reported satisfactory outcomes in terms of clinical and radiological evaluations. Moreover, our results showed an improvement of sport activity levels, with patients recovering sports activity within three months of surgery and without limitation in the execution of preferred activities. LEVEL OF EVIDENCE IV.

Abstract
Background Initially known as the reproductive hormone, relaxin was shown to possess other therapeutically useful properties that include extracellular matrix remodeling, anti-inflammatory, anti-ischemic and angiogenic effects. All these findings make relaxin a potential drug for diverse medical applications. Its precursor, pro-relaxin, is an 18 kDa protein, that shows activity in in vitro assays. Since extraction of relaxin from animal tissues raises several issues, prokaryotes and eukaryotes were both used as expression systems for recombinant relaxin production. Most productive results were obtained when using Escherichia coli as a host for human relaxin expression. However, in such host, relaxin precipitated in the form of inclusion bodies and, therefore, required several expensive recovery steps as cell lysis, refolding and reduction. Results To overcome the issues related to prokaryotic expression here we report the production and purification of secreted human pro-relaxin H2 by using the methylotrophic yeast Pichia pastoris as expression host. The methanol inducible promoter AOX1 was used to drive expression of the native and histidine tagged forms of pro-relaxin H2 in dual phase fed-batch experiments on the 22 L scale. Both protein forms presented the correct structure, as determined by mass spectrometry and western blotting analyses, and demonstrated to be biologically active in immune enzymatic assays. The presence of the tag allowed to simplify pro-relaxin purification obtaining higher purity. Conclusions This work presents a strategy for microbial production of recombinant human pro-relaxin H2 in Pichia pastoris that allowed the obtainment of biologically active pro-hormone, with a final concentration in the fermentation broth ranging between 10 and 14 mg/L of product, as determined by densitometric analyses.

Abstract
Osteoporosis is the most common bone disease, affecting millions of people and causing a high risk of fractures and a loss of quality of life. It is characterized by low bone mass and microarchitectural deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fracture. A primary method of prevention, in order to reduce the risk of fractures, is represented by an appropriate lifestyle and a correct diet. There are potentially numerous nutrients and dietary components that can influence bone health, and these range from macronutrients to micronutrients as well as bioactive food ingredients. The purpose of this review is to overview osteoporosis, including its definition, etiology, and incidence, and then provide some information on possible dietary strategies for optimizing bone health and preventing osteoporosis. A correct diet to prevent osteoporosis should contain adequate amounts of calcium, vitamins D and K, protein, and fatty acids. The effects of these elements are briefly discussed, reporting on their correlation with bone benefits.

Abstract
In 2012 we reviewed a consecutive series of 92 uncemented THRs performed between 1986 and 1991 at our institution using the CLS Spotorno stem, in order to assess clinical outcome and radiographic data at a minimum of 21 years. The series comprised 92 patients with a mean age at surgery of 59.6 years (39 to 77) (M:F 43;49). At the time of this review, seven (7.6%) patients had died and two (2.2%) were lost to follow-up. The 23-year Kaplan-Meier survival rates were 91.5% (95% confidence intervals (CI) 85.4% to 97.6%; 55 hips at risk) and 80.3% (95% CI, 71.8% to 88.7%; 48 hips at risk) respectively, with revision of the femoral stem or of any component as endpoints. At the time of this review, 76 patients without stem revision were assessed clinically and radiologically (mean follow-up 24.0 years (21.5 to 26.5)). For the 76 unrevised hips the mean Harris hip score was 87.1 (65 to 97). Femoral osteolysis was detected in five hips (6.6%) only in Gruen zone 7. Undersized stems were at higher risk of revision owing to aseptic loosening (p = 0.0003). Patients implanted with the stem in a varus position were at higher risk of femoral cortical hypertrophy and thigh pain (p = 0.0006 and p = 0.0007, respectively). In our study, survival, clinical outcome and radiographic data remained excellent in the third decade after implantation. Nonetheless, undersized stems were at higher risk of revision owing to aseptic loosening.

Abstract
BACKGROUND Congenital talipes equinovarus (CTEV) is a common but still not fully understood disorder of the lower limb. It is usually defined as a fixation of the foot in adduction, supination, and varus. Different treatment options exist including the Ponseti method. AIM We report here the results obtained in infants with CTEV treated by the Ponseti method. PATIENTS AND METHODS Eighty two patients (114 clubfeet) were enrolled at the Orthopaedic Clinic of Catania University during the period of March 2004 to January 2010 and followed prospectively up to February 2011: 56 patients (68.29%) were male, the anomaly was bilateral in 32 (39%) cases, unilateral in 50 (60.9%) in the right side in 28 (56%). The mean age at initiation of treatment was 14 days (range 3-81 days), severity of the club foot deformity by the Pirani Severity score was 5.56 points (range 4.3-6 points). Total numbers of Ponseti casts before tenotomy, details of tenotomy, and compliance with CTEV brace were recorded. Clinical evaluation was performed using the functional Ponseti Scoring System. Mean follow up was 4 years: range 13-83 months. RESULTS An average of 6.6 casts was necessary before performing the tenotomy. Tenotomy was performed by a single surgeon (V.P.) in a total of 68 patients (82.93%) always in an operating room under general anaesthesia by a percutaneous approach at a mean age of 106 days (range 45-213 days). Compliance with CTEV brace was satisfactory in 79 patients (96.3%). Functional Ponseti Scores were good/excellent in 79 (96.34%) patients (109 clubfeet; 95.61%). Only 3 patients; 3.7% (5 clubfeet; 4.4%) suffered relapse. Poor compliance with the Denis Browne splint was thought to be the main cause of failure. CONCLUSIONS The Ponseti method provides an excellent outcome at follow up in the treatment of congenital idiopathic clubfoot.

Abstract
INTRODUCTION Sepsis is a major cause of significant morbidity and mortality in neutropenic patients. Blood culture remains the gold standard in the microbiological diagnosis of bacterial or fungal bloodstream infections, but it has clear limits of rapidity and sensitivity. The objective of the study was to compare the real-time polymerase chain reaction (RT-PCR) with automated blood cultures (BC) method in detection in whole blood of pathogens in febrile neutropenic patients with hematological malignancies. METHODS A total of 166 consecutive febrile neutropenic patients were enrolled. Blood samples for cultures and SeptiFast testing were obtained at the onset of fever, before the implementation of empirical antibiotic therapy. RESULTS Forty (24.1%) samples out of the 166 blood samples tested, were positive by at least one method. Twenty-three (13.9%) samples were positive by blood culture and 38 (22.9%) by multiplex real-time PCR. The analysis of concordance evidenced a low correlation between the two methods (n = 21; 52.5%), mainly due to samples found negative by culture but positive with the Septi-Fast assay. Sensitivity, specificity, and positive and negative predictive values of RT-PCR were 91.3%, 88.1%, 55.3%, and 98.4%, respectively, compared with BC. DISCUSSION Multiplex real-time PCR assay improved detection of the most bacteria associated with febrile neutropenia episodes. Further studies are needed to assess the real advantages and clinical benefits that molecular biology tests can add in diagnosis of sepsis.

Abstract
BACKGROUND The urokinase plasminogen activator receptor (u-PAR) focuses the proteolytic activity of the urokinase plasminogen activator (u-PA) on the endothelial cell surface, thus promoting angiogenesis in a protease-dependent manner. The u-PAR may exist in a glycophosphatidylinositol-anchored and in a soluble form (soluble u-PAR [Su-PAR]), both including the chemotactic Ser⁸⁸ -Arg-Ser-Arg-Tyr⁹² internal sequence. OBJECTIVE To investigate whether Su-PAR may trigger endothelial cell signaling leading to new vessel formation through its chemotactic Ser⁸⁸ -Arg-Ser-Arg-Tyr⁹² sequence. METHODS AND RESULTS In this study, the formation of vascular-like structures by human umbilical vein endothelial cells was assessed by using a matrigel basement membrane preparation. First, we found that Su-PAR protein promotes the formation of cord-like structures, and that this ability is retained by the isolated Ser(88) -Arg-Ser-Arg-Tyr⁹² chemotactic sequence, the maximal effect being reached at 10 nmol L⁻¹ SRSRY peptide (SRSRY). This effect is mediated by the α(v) β₃ vitronectin receptor, is independent of u-PA proteolytic activity, and involves the internalization of the G-protein-coupled formyl-peptide receptor in endothelial cells. Furthermore, exposure of human saphenous vein rings to Su-PAR or SRSRY leads to a remarkable degree of sprouting. Finally, we show that Su-PAR and SRSRY promote a marked response in angioreactors implanted into the dorsal flank of nude mice, retaining 91% and 66%, respectively, of the angiogenic response generated by a mixture of vascular endothelial growth factor and fibroblast growth factor type 2. CONCLUSIONS Our results show a new protease-independent activity of Su-PAR that stimulates in vivo angiogenesis through its Ser⁸⁸ -Arg-Ser-Arg-Tyr⁹² chemotactic sequence.

Abstract
The crystal-state preferred conformation of the terminally blocked homooctapeptide from the C(alpha,alpha)-dimethylated alpha-aminoisobutyric acid (Aib) residue, pBrBz-(Aib)(8)-OBu(t), in which pBrBz is para-bromobenzoyl and OBu(t) is tert-butoxy, determined by x-ray diffraction analysis using direct methods, was found to be a 3(10)-helix stabilized by six consecutive intramolecular N-H....O=C hydrogen bonds of the C(10)-III (or III') type. This is the first observation at atomic resolution of a regular 3(10)-helix longer than two complete turns. The solid-state structural analysis was extended to the terminally blocked, alpha-aminoisobutyric acid-rich octapeptide corresponding to the 2-9 sequence of the peptaibol antibiotics emerimicins III and IV, pBrBz-Aib(3)-L-Val-Gly-L-Leu-Aib(2)-OMe. Again, this peptide adopts a (right-handed) 3(10)-helical structure, although slightly distorted at the level of the L-leucine residue. The role of specific amino acid sequence and peptide main-chain length in stabilizing either the 3(10)- or the alpha-helical conformation and their possible implications on the nature of the channel formed by peptaibol antibiotics in the membrane are also briefly discussed.

Abstract
Lymphangiomatosis is a well-recognized congenital benign tumour, frequently seen in infancy and childhood, characterized by the presence of multiple lymphangiomas. Diffuse lymphangiomatosis also involving bony tissue is called Gorham's disease. This condition generally affects somatic soft tissue, where lymphatics are normally found. A predilection of this affection for bone, thoracic and neck involvement is well known, while involvement of abdominal viscera is very unusual. In bone this non malignant proliferation of lymphatic channels results in destruction and resorption of the osseous matrix. We report on a child in whom lymphangiomatosis involved both the bone and the spleen. A review of 166 cases is also reported.

Abstract
BACKGROUND In 1997, the Intergruppo Italiano Linfomi started a randomized trial to evaluate, in unfavorable stage IA and IIA Hodgkin's lymphoma (HL) patients, the efficacy and toxicity of the low toxic epirubicin, vinblastine and etoposide (EVE) regimen followed by involved field radiotherapy in comparison to the gold standard doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD) regimen followed by the same radiotherapy program. PATIENTS AND METHODS Patients should be younger than 65 years with unfavorable stage IA and IIA HL (i.e. stage IA or IIA with bulky disease and/or subdiaphragmatic disease, erythrocyte sedimentation rate higher than 40, extranodal (E) involvement, hilar involvement and more than three involved lymph node areas). RESULTS Ninety-two patients were allocated to the ABVD arm and 89 to the EVE arm. Complete remission (CR) rates at the end of treatment program [chemotherapy (CT) + RT] were 93% and 92% for ABVD and EVE arms, respectively (P = NS). The 5-year relapse-free survival (RFS) rate was 95% for ABVD and 78% for EVE (P < 0.05). As a consequence of the different relapse rate, the 5-year failure-free survival (FFS) rate was significantly better for ABVD (90%) than for EVE (73%) arm (P < 0.05). No differences in terms of overall survival (OS) were observed for the two study arms. CONCLUSIONS In unfavorable stage IA and IIA HL patients, no differences were observed between ABVD and EVE arms in terms of CR rate and OS. EVE CT, however, was significantly worse than ABVD in terms of RFS and FFS and cannot be recommended as initial treatment for HL.

Abstract
Haemopoietic stem cell therapy is an increasingly adopted procedure in the treatment of patients with malignant lymphoma. In this retrospective analysis, we evaluated 262 patients, 57 (22%) with Hodgkin's and 205 (78%) with non-Hodgkin's lymphomas (NHL), and 665 harvesting procedures in order to assess the impact of poor mobilization on survival and to determine the factors that may be predictive of CD34(+) poor mobilization. The mobilization chemotherapy regimens consisted of high-dose cyclophosphamide in 92 patients (35.1%) and a high-dose cytarabine-containing regimen (DHAP in 87 patients -(33.2%), MAD in 83 (31.7%)). The incidence of poor mobilizers (<2 x 10(6) CD34(+) cells/kg) was 17.9% overall, with a 10% of very poor mobilizers (< or = 1 x 10(6)/kg). Refractory disease status and chemotherapeutic load (>3 regimens) before mobilization played a negative role and were associated with poor mobilization. Survival analysis of all harvested patients showed an overall survival at 3 years of 71% in good mobilizers vs 33% in poor mobilizers (P=0.002). The event-free survival at 3 years was 23% in poor mobilizers and 58% in good mobilizers (P=0.04). We conclude that in NHL patients, poor mobilization status is predictive of survival.

Abstract
Total hip replacement surgery carries the risk of thromboembolic complications, which could be fatal. Over the last three decades however, the risk has decreased considerably thanks to progress made in the understanding of the physiopathogenetic mechanism of thromboembolic disease and perioperative prophylaxis. It is the purpose of this study to discuss the main medical and surgical preventive measures that must be carried out before, during and immediately after surgery. The old concept of deciding thromboembolic prophylaxis after surgery is now obsolete.

Abstract
BACKGROUND In advanced age the prognosis of Hodgkin's lymphoma (HL) is poor, but, as a consequence of the low incidence of HL in the elderly, prospective studies are lacking and the best treatment strategy is difficult to define. PATIENTS AND METHODS One-hundred and five HL patients over 65 years of age were treated homogeneously with an original reduced-intensity regimen designed for HL in the elderly containing vinblastine, cyclophosphamide, procarbazine, etoposide, mitoxantrone and bleomycin (VEPEMB). Forty-eight early stage (IA-IIA) patients received three courses of VEPEMB followed by involved field irradiation. Fifty-seven advanced stage (IIB-IV) patients received six courses followed by radiotherapy limited to the areas of bulky disease. RESULTS Mean age was 71 years (range 66-83). Co-morbidities were present in 39 patients (37%). A treatment plan modification for poor tolerance or toxicity was needed in 18 patients. Results were satisfactory, even if they were better in early rather than in advanced stage disease: complete response rate 98% versus 58% (P <0.01); 5-year failure-free survival 79% versus 34% (P <0.01). The results were affected by advanced stage, systemic symptoms and co-morbidity but they were not influenced by age itself. CONCLUSIONS VEPEMB is an effective and low toxic regimen for HL in the elderly. Co-morbidity is a prognostic factor more important than age itself.

Abstract
Congenital disorder of glycosylation (CDG) type IA (phosphomannomutase deficiency) is the most common of a group of inherited metabolic disorders that are due to defective glycosylation of glycoproteins. CDG-IA is clinically characterized by major nervous system involvement and various organs are affected to a variable degree. Common clinical findings are skeletal changes including peculiar thoracic deformity and joint restriction, while a major radiological feature is diffuse osteopenia. The aim of this study was to measure bone density and biochemical markers of bone turnover in three patients with CDG-IA, whose age ranged between 14 and 27 years. We found that bone mass, as judged by standard densitometry, quantitative computed tomography and ultrasonography, was lower in patients than in age- and sex-matched healthy controls. Biochemical indexes of bone resorption including free pyridinoline levels in serum and pyridinoline and deoxypyridinoline urinary excretions were normal, whereas bone formation markers (serum osteocalcin and serum bone-specific alkaline phosphatase) activity were increased. These results suggest that low bone density is a component of CDG-IA, which should be considered among inherited metabolic diseases with decreased bone mass. We hypothesize that hypoglycosylation of noncollagenous bone proteins may contribute to the osteopenia observed in these patients. From a clinical point of view, our observation shows that bone density measurements can provide a quantitative assessment of bone involvement in such diseases.

Abstract
Heterotopic ossification (HO) is a frequent complication following total hip arthroplasty (THA). At present, the etiology HO is unknown, however, genetic predisposition may be a cause of HO in individuals in whom no risk factors can be detected. The goal of this study was to investigate the HLA system, searching for any correlation with the presence of HO after THA. Thirty-five patients of Sicilian origin were operated on between January 1997 and January 1999 for cementless THA under regional anesthesia. The entire series was divided into three groups and all underwent histocompatibility typing. Group I was made up of 10 patients who presented with HO Brooker grades 1 and 2 after THA; group 2 comprised 7 patients affected by grades 3 and 4 HO after THA; and group 3 was made up of 18 subjects who presented with one or more preoperative risk factors for developing peri-prosthetic HO before undergoing THA. No positivity for HLA-B27 antigen was observed, but there was as an increase in HLA-B18 (with respect to that in the Sicilian population) in patients with HO following THA. The main conclusion from the study is that there is a strong correlation between the presence of the antigens HLA-A2 and HLA-B18 in patients with HO grades 3 and 4.

Abstract
Our study analyzes the mobilization of hematopoietic stem cells after two chemotherapeutic regimens in non-Hodgkin's lymphoma (NHL) patients. The study included 72 patients with NHL (42 follicular and 30 large cells). The mean age was 37 years (range 17-60). Sixty-four patients (88.9%) had stage III-IV disease. Forty-eight patients (66.7%) had bone marrow involvement. Systemic B symptoms were present in 42 patients (58.3%). Mobilization chemotherapy regimens were randomly assigned as DHAP in 38 patients (52.7%) or cyclophosphamide (CPM) (5 g/m(2)) in 34 (47.2%) and the results of 132 procedures were analyzed. At the time of PBSC mobilization, 46 patients (63.9%) were considered to be responsive (complete remission, partial remission or sensitive relapse) and 26 (36.1%) not responsive (refractory relapse or refractory to therapy). Pre-apheresis CD34+ blood cell count and number of previous chemotherapy treatments were used to predict the total number of CD34+ cells in the apheresis product. The mobilizing regimens (CPM or DHAP) were similar in achieving the threshold CD34+ cell yield, for optimal engraftment. Since DHAP was very effective as salvage treatment, we suggest using DHAP as a mobilizing regimen in patients with active residual lymphoma at the time of stem cell collection.

Abstract
De novo design of proteins provides an attractive approach to uncover the essential features required for their functions. Previously, we described the design and crystal structure determination of a di-Zn(II) complex of "due-ferri-1" (DF1), a protein patterned after the diiron-dimanganese class of redox-active proteins [Lombardi, A.; Summa, C.; Geremia, S.; Randaccio, L.; Pavone, V.; DeGrado, W. F. Proc. Natl. Acad. Sci. U.S.A. 2000, 97, 6298-6305]. The overall structure of DF1, which contains a carboxylate-bridged dinuclear metal site, agrees well with the intended design. However, access to this dimetal site is blocked by a pair of hydrophobic leucine residues (L13 and L13'), which prevent facile entry of metal ions and small molecules. We have now taken the next step in the eventual construction of a catalytically active metalloenzyme by engineering an active site cavity into DF1 through the replacement of these two leucine residues with smaller residues. The crystal structure of the dimanganous form of L13A-DF1 indeed shows a substrate access channel to the dimetal center. In the crystal structure, water molecules and a ligating dimethyl sulfoxide molecule, which forms a monatomic bridge between the metal ions, occupy the cavity. Furthermore, the diferric form of a derivative of L13A-DF1, DF2, is shown to bind azide, acetate, and small aromatic molecules.

Abstract
Congenital insensitivity to pain with anhidrosis is an autosomal recessive hereditary disorder characterized by recurrent episodic fever, anhidrosis (inability to sweat), absence of reaction to noxious stimuli, self-mutilating behavior, and mental retardation. The human TRKA gene (NTRK1), located on chromosome 1q21-q22 encodes the receptor tyrosine kinase for nerve growth factor. We reported that TRKA is the gene responsible for CIPA and we developed a comprehensive strategy to screen for TRKA mutations and polymorphisms, as based on the gene's structure and organization. Here we report eight novel mutations detected as either a homozygous or heterozygous state in nine CIPA families from five countries. Mendelian inheritance of the mutations was confirmed in seven families for which samples from either parent were available. However, non-mendelian inheritance seems likely for the family when only samples from the mother and siblings, (but not from the father) were available. A paternal uniparental disomy for chromosome 1 is likely to be the cause of reduction to homozygosity of the TRKA gene mutation in this family. Interestingly, a Hispanic patient from the USA has two autosomal genetic disorders, CIPA and pyruvate kinase deficiency, whose genetic loci are both mapped to a closely linked chromosomal region. A splice mutation and a missense mutation were detected in the TRKA and PKLR genes from the homozygous proband, respectively. Thus, concomitant occurrence of two disorders is ascribed to a combination of two separate mutant genes, not a contiguous gene syndrome. This finding suggests a mechanism responsible for two autosomal genetic disorders in one patient. All these data further support findings that TRKA defects can cause CIPA in various ethnic groups. This will aid in diagnosis and genetic counseling of this painless but severe genetic disorder.

Abstract
OBJECTIVE To evaluate whether some ultrasound parameters of ovarian morphology can discriminate between control women and patients with polycystic ovary syndrome (PCOS). DESIGN Retrospective data analysis. SETTING Volunteers women in an academic research environment. PATIENT(S) Eighty amenorrheic or oligomenorrheic women and 30 normal ovulatory control participants. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) We evaluated ovarian volume, area, stroma, and the stroma/total area (S/A) ratio by use of transvaginal pelvic ultrasound; and we assayed serum levels of gonadotropin, androgen, and estradiol during the early follicular phase (days 2 to 5) of the menstrual cycle in regularly cycling controls and on a random day in amenorrheic patients. RESULT(S) Patients with PCOS showed significantly higher ovarian volume, area, stroma, and mean S/A ratio when compared to multifollicular and control groups. Cut-off values have been defined for ovarian volume (13.21 mL), area (7.00 cm2), stroma (1.95 cm2), and S/A ratio (0.34). The sensitivity for PCOS diagnosis was 21%, 4%, 62%, and 100%, respectively. The S/A ratio showed the most significant correlation with the androgen levels. CONCLUSION(S) The evaluation of the S/A ratio can differentiate between PCOS and control or multifollicular women with both a sensitivity and a specificity of 100%. Furthermore, this ultrasound parameter is strictly related to hormonal milieu and to anthropometric characteristics.

Abstract
Between July 1977 and December 1983, 80 patients underwent 120 arthroplasties using a total condylar knee prostheses. Forty-one patients (68 knees) died and 13 patients were lost to followup. Twenty-six patients with 34 total condylar replacements were available for clinical followup. During the followup, 10 knees in nine patients (8.3%) from the overall 80 patients (120 knees) underwent revision; three (four knees) for aseptic loosening, one for periprosthetic fracture, three for infection, and two patients underwent revision for pain. Three revisions (three patients) occurred in the group of 26 patients available for followup. The average age of this group of patients at followup was 78 years (range, 53-94 years). There were 10 men and 16 women. Considering the high mean age of the patients in the series and patients' overall health status, the clinical results were extremely good. Kaplan-Meier analysis showed a survivorship of 91% at 23 years followup, considering revision as an end point. Although there have been several changes in total knee replacement designs, materials, and implantation techniques, the long-term outcome of the original total condylar knee prosthesis is excellent.

Abstract
Certain chemokines act as natural antagonists of human immunodeficiency virus (HIV) by blocking key viral coreceptors, such as CCR5 and CXCR4, on the surface of susceptible cells. Elucidating the structural determinants of the receptor-binding and HIV-inhibitory functions of these chemokines is essential for the rational design of derivative molecules of therapeutic value. Here, we identify the structural determinants of CCR5 recognition and antiviral activity of the CC chemokine RANTES, showing that critical residues form a solvent-exposed hydrophobic patch on the surface of the molecule. Moreover, we demonstrate that the biological function is critically dependent on dimerization, resulting in the exposure of a large ( approximately 180 A2), continuous hydrophobic surface. Relevant to the development of novel therapeutic approaches, we designed a retroinverted RANTES peptide mimetic that maintained both HIV- and chemotaxis-antagonistic functions.
