Abstract
OBJECTIVE The ProCCard study tested whether combining several cardioprotective interventions would reduce the myocardial and other biological and clinical damage in patients undergoing cardiac surgery. DESIGN Prospective, randomized, controlled trial. SETTING Multicenter tertiary care hospitals. PARTICIPANTS 210 patients scheduled to undergo aortic valve surgery. INTERVENTIONS A control group (standard of care) was compared to a treated group combining five perioperative cardioprotective techniques: anesthesia with sevoflurane, remote ischemic preconditioning, close intraoperative blood glucose control, moderate respiratory acidosis (pH 7.30) just before aortic unclamping (concept of the "pH paradox"), and gentle reperfusion just after aortic unclamping. MEASUREMENTS AND MAIN RESULTS The primary outcome was the postoperative 72-h area under the curve (AUC) for high-sensitivity cardiac troponin I (hsTnI). Secondary endpoints were biological markers and clinical events occurring during the 30 postoperative days and the prespecified subgroup analyses. The linear relationship between the 72-h AUC for hsTnI and aortic clamping time, significant in both groups (p < 0.0001), was not modified by the treatment (p = 0.57). The rate of adverse events at 30 days was identical. A non-significant reduction of the 72-h AUC for hsTnI (-24%, p = 0.15) was observed when sevoflurane was administered during cardiopulmonary bypass (46% of patients in the treated group). The incidence of postoperative renal failure was not reduced (p = 0.104). CONCLUSION This multimodal cardioprotection has not demonstrated any biological or clinical benefit during cardiac surgery. The cardio- and reno-protective effects of sevoflurane and remote ischemic preconditioning therefore remain to be demonstrated in this context.

Abstract
BackgroundSince the COVID-19 vaccination campaign was launched all over Europe, there has been general agreement on how benefits of SARS-CoV2 vaccines outweigh the risks in patients with rare connective tissue diseases (rCTDs). Yet, there is still limited evidence regarding safety and efficacy of such vaccines in these patients, especially in the long-term. For this reason, in the framework of ERN-ReCONNET, an observational long-term study (VACCINATE) was designed in order to explore the long-term outcome of COVID-19 vaccination in rCTDs patients. The consent form was developed thanks to the involvement of the ERN ReCONNET ePAG Advocates (European Patients Advocacy Group).ObjectivesTo evaluate the safety profile of COVID-19 vaccination in rCTDs patients and the potential impact on disease activity. Primary endpoints were the prevalence of adverse events (AEs) and of disease exacerbations post-vaccination. Secondary endpoints were the proportion of serious adverse events (SAEs) and adverse events of special interest for COVID-19 (adapted from https://brightoncollaboration.us/wp-content/uploads/2021/01/SO2_D2.1.2_V1.2_COVID-19_AESI-update-23Dec2020-review_final.pdf)MethodsThe first ad-interim analysis of the VACCINATE study involved 9 ERN-ReCONNET Network centres. Patients over 18 years of age with a known rCTD and who received vaccine against COVID-19 were eligible for recruitment. Demographic data and diagnoses were collected at the time of enrolment, while the appearance of AEs and potential disease exacerbations were monitored after one week from each vaccination dose, and then after 4, 12 and 24 weeks from the second dose. A disease exacerbation was defined as at least one of the following: new manifestations attributable to disease activity, hospitalization, increase in PGA from previous evaluation, addition of corticosteroids or immunosuppressants.ResultsA cohort of 300 patients (261 females, mean age 52, range 18-85) was recruited. Systemic lupus erythematosus (44%) and systemic sclerosis (16%) were the most frequent diagnoses, followed by Sjogren’s syndrome (SS,12%), idiopathic inflammatory myositis (IMM,10%), undifferentiated connective tissue disease (UCTD,8%), mixed connective tissue disease (MCTD,4%), Ehlers-Danlos’s syndrome (EDS,4%), antiphospholipid syndrome (APS,2%). AEs appearing 7 days after the first and second doses were reported in 93 (31%) and 96 (32%) patients respectively, mainly represented by fatigue, injection site reaction, headache, fever and myalgia. Otitis, urticaria, Herpes Simplex-related rash, stomatitis, migraine with aura, vertigo, tinnitus and sleepiness were reported with very low frequency. Less than 2% of patients experienced AEs within 24 weeks from the second dose. No SAEs or AEs of special interest were observed in the study period. There were 25 disease exacerbations (8%), 7 of which severe. The highest number of exacerbations was observed after 4 weeks from the second dose (12 within week 4, 6 within week 12 and 7 within week 24). Disease exacerbation was most frequent in patients with EDS (33%) and MCTD (25%).ConclusionThis preliminary analysis shows that COVID-19 vaccination is safe in rCTDs patients. AEs appear most often early after vaccination and are usually mild. Disease exacerbations are not frequent, but can be potentially severe and tend to occur most frequently within the first month after vaccination. Exacerbations can also occur 3-6 months after vaccination, although a causal relationship with the vaccination remains to be established. Our present data underline the importance of long-term observational studies.Table 1.AEs and disease exacerbations per diseaseDiagnosisPatients enrolled (%) (n=300)EAs after 1st and 2nd dose (%)Exacerbations (%)APS25714EDS45033IIM10527MCTD44225SS12598SLE44698SSC16492UCTD850-AcknowledgementsVACCINATE is a study promoted by the European Reference Network on rare and complex connective tissue diseases, ERN ReCONNET.

Abstract
PURPOSE Ultrasound (US) allows non-invasive repeated assessments of diaphragmatic excursion (DE) and thickening fraction (DTF) at the bedside, reflecting diaphragmatic dysfunction (DD). We aimed at determining the prevalence and time-course of DD following elective thoracic surgery and the association with postoperative complications. MATERIAL AND METHODS Prospective, single-centre, observational study with consecutive patients undergoing thoracic surgery. DE/DTF were measured by two observers blinded to each other at 3 different time-points: prior to surgery, immediately after extubation and on postoperative day 3. The changes in DE/DTF of both hemi-diaphragms over time were compared according to the side (operated/non-operated) using a two-way-ANOVA. The association with postoperative complications was assessed using logistic regression. RESULTS Fifty patients, 60% males, aged 60 ± 15 years were included. Surgical procedures included lobectomy (n = 30), wedge-resection (n = 17) or pneumonectomy (n = 3). On the operated side, we observed a decrease in DE/DTF at D0 (-0.71 ± 0.12 mm, P < 0.05; -44 ± 30%, P < 0.05) and D3 (-0.82 ± 0.19 mm, P < 0.05; -39 ± 19%, P < 0.05) with respect to preoperative and non-operated side values over the study period. Persistent DD on the operated side was associated with an increased risk of lung infection (OR: 9.0, 95%CI [1.92-65.93], P = 0.001), ICU-admission (OR: 3.9, 95%CI [1.10-15.53], P = 0.04) according to univariate analysis and a prolonged length in hospital (OR: 1.3, 95%CI [1.1-1.7], P = 0.016) according to multivariate analysis. CONCLUSIONS Thoracic surgery generates DD mainly observed on the operated side, which persists at least up to postoperative D3 and is associated with an increase in hospital stay.

Abstract
OBJECTIVE To analyze the impact of the modification of the authors' institutional protocol on outcomes after extracorporeal cardiopulmonary resuscitation (ECPR) for out-of-hospital cardiac arrest (OHCA). DESIGN An observational analysis. The protocol complied with national recommendations. A further eligibility criterion was added since January 2015: the presence of sustained shockable rhythm at extracorporeal life support (ECLS) implantation. To assess the impact of this change, patients were divided into two groups: (1) from January 2010 to December 2014 (group A) and (2) from January 2015 to December 2019 (group B). The primary endpoint was survival to hospital discharge with good neurologic outcome. Predictors of survival were searched with multivariate analyses. SETTING University hospital. PARTICIPANTS Adult patients supported with ECPR for refractory OHCA. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS From January 2010 to December 2019, 85 patients had ECLS for OHCA (group A, n = 68, 80%; group B, n = 17, 20%). The mean age was 42.4 years, 78.8% were male. The rate of implantation of ECLS was significantly lower in group B (p = 0.01). Mortality during ECLS support was significantly lower (58.8 v 86.8%; p = 0.008), and the weaning rate was significantly higher (41.2 v 13.2%; p = 0.008) in group B. Survival to discharge with good neurologic outcome was significantly improved (23.5 v 4.4%; p = 0.027) in group B. A sustained shockable rhythm was the only independent predictor of survival to hospital discharge with good neurologic outcome. CONCLUSIONS The modification of the authors' institutional protocol throughout the further criterion of sustained shockable rhythm yielded a favorable impact on outcomes after ECPR for OHCA.

Abstract
Objectives Mottling score is estimated from 0-5 according to mottling over the knee and described as clinical evaluation of tissue perfusion. This score was developed with ancient definitions of sepsis without lactate level, a major prognostic parameter when superior to 2 mmol/L. This study describes mottling incidence and mottling score in septic shock patients according to lactate level. Materials and methods We reanalyzed our prospective study in a French tertiary hospital in the intensive care unit (ICU) which studied mottling score and thermography correlation. Patients admitted to septic shock diagnosis and requiring vasoactive drugs were included. We recorded hemodynamic variables, mottling score, and lactate. Data collection was realized at ICU admission (H0) and after six hours (H6). Results Forty-three patients were included. Mean age was 67 (±4), mean sequential organ failure assessment (SOFA) score was 11 (8-12), and SAPS II 58 ±20. Mortality rate at day 28 was 30%. Among patients with lactate ≥2 mmol/L, mottling was more prevalent in 82.6% vs 47.4% (p value = 0.016), and at H6 mottling score was higher (p value = 0.009). Although, mottling incidence was not different between dead (85%) and survivors (81%; p value = 0.795). Conclusion A new sepsis definition implies a new epidemiology in mottling according to lactate threshold. Patients with lactate ≥2 mmol/L presented a higher incidence and score of mottling. However, mortality was not influenced by mottling in this study. Clinical significance Arterial lactate is a major prognostic parameter when superior to 2 mmol/L.A new definition of sepsis was published in 2016 with a new paradigm and epidemiology of septic shockPatients with lactate ≥2 mmol/L presented a higher incidence and score of mottling.Mottling score is a clinical sign of microcirculatory alteration, related to lactate level in septic shock.

Abstract
Introduction Mottling score, defined by 5 areas over the knee is developed to evaluate tissue perfusion at bedside. Because of the subjective aspect of the score, we aimed to compare mottling score and skin temperature in septic shock with infrared thermography in ICU and the correlation to survival. Methods We conducted a prospective and observational study in a teaching hospital in France during 8 months in ICU. All patients with sepsis requiring vasoactive drugs were included. We recorded epidemiologic data, hemodynamic parameters, mottling score and skin temperature with a thermic camera of the 5 mottling areas around the knee (temperatures recorded with FLIR™ software) at bedside. Measures were performed at ICU admission (H0) and six hours after initial resuscitation (H6). Results 46 patients were included. Median age was 69 (60–78), SOFA score 11 (8–12) mean SAPS II was 57±20 and 28-day mortality rate was 30%. Patients with mottling (score≥1), had a skin temperature of the knee significantly lower (30.7 vs 33,2°C p = 0.01 at H6) than patients without mottling (score = 0). Skin temperatures of the knee in mottling groups 1 to 5 were similar at H0 and H6. Neither mottling score nor skin temperature of the knee were associated with prognostic regarding day-28 mortality. Conclusions Skin temperature measured with infrared thermography technology around the knee is lower when mottling sign is present and sign microcirculation alterations. This method, compared to standard mottling score is objective and allows data collections. However, this method failed to predict mortality in ICU patients.

Abstract
Ellis-van Creveld syndrome (EvC) is a chondral and ectodermal dysplasia caused by biallelic mutations in the EVC, EVC2 and WDR35 genes. A proportion of cases with clinical diagnosis of EvC, however, do not carry mutations in these genes. To identify the genetic cause of EvC in a cohort of mutation-negative patients, exome sequencing was undertaken in a family with 3 affected members, and mutation scanning of a panel of clinically and functionally relevant genes was performed in 24 additional subjects with features fitting/overlapping EvC. Compound heterozygosity for the c.2T>C (p.Met1?) and c.662C>T (p.Thr221Ile) variants in DYNC2LI1, which encodes a component of the intraflagellar transport-related dynein-2 complex previously found mutated in other short-rib thoracic dysplasias, was identified in the 3 affected members of the first family. Targeted resequencing detected compound heterozygosity for the same missense variant and a truncating change (p.Val141*) in 2 siblings with EvC from a second family, while a newborn with a more severe phenotype carried 2 DYNC2LI1 truncating variants. Our findings indicate that DYNC2LI1 mutations are associated with a wider clinical spectrum than previously appreciated, including EvC, with the severity of the phenotype likely depending on the extent of defective DYNC2LI1 function.

Abstract
OBJECTIVE To systematically examine the effects of dopaminergic agents (modafinil, armodafinil, pramipexole, methylphenidate, and amphetamines) on bipolar depression outcomes. METHODS Meta-analysis of randomized controlled trials was performed to assess the efficacy and safety of treatment with dopaminergic agents in bipolar depression. In a secondary analysis, findings from both randomized controlled trials and high-quality observational studies were pooled by means of meta-analytic procedures to explore dopaminergic treatment-related new mania. RESULTS Nine studies (1716 patients) were included in our meta-analysis of randomized controlled trials. Treatment with dopaminergic agents for bipolar depression was associated with an increase in both response (1671 individuals, RR 1.25, 95% CI 1.05 to 1.50) and remission rates (1671 individuals, RR 1.40, 95% CI 1.14, 1.71). There was no evidence of an increased risk of mood switch associated with this treatment (1646 individuals, RR 0.96, 95% CI 0.49, 1.89). Our secondary analysis (1231 individuals) yielded a cumulative incidence of mood switch of 3% (95% CI 1.0, 5.0) during a mean follow-up period of 7.5 months. CONCLUSIONS Preliminary findings suggest that dopaminergic agents may represent a useful alternative for the treatment of bipolar depression, with no evidence for a related increase in the risk of mood destabilization during short-term follow-up.

Abstract
The two phenotypes of both limited and diffuse systemic sclerosis (SSc) have different forms of pulmonary involvement: pulmonary arterial hypertension (limited phenotype) or interstitial lung disease (ILD) (diffuse phenotype). We aimed to investigate whether Th17-related cytokines, as measured in exhaled breath condensate (EBC) and in serum were connected to ILD in diffuse SSc patients. We found that for both limited and diffuse SSc, the EBC levels of all cytokines and most of the cytokine serum levels were significantly higher in patients than in controls, while, the EBC levels of Th-17 cytokines and the serum levels of IL-10 and TNF-α were significantly higher in diffuse than in limited SSc. Moreover, the thoracic CT-scan score of ILD was significantly associated with the EBC levels of IL-1 beta and with the serum IL-23, TNF-α and IL-10 levels, whereas lung carbon monoxide diffusing capacity was negatively related to the EBC levels of IL-1 beta, IL-17 and serum IL-10. Serum IL-23 was also inversely correlated with vital capacity. In conclusion, in diffuse SSc patients our results show a clear link between Th-17 cytokines measured both in EBC and in serum with interstitial lung involvement. This highlights how important it is to target Th-17 cytokines when developing new treatments for lung fibrosis.

Abstract
Steroid hormones are important players to regulate adult neurogenesis in the dentate gyrus of the hippocampus, but their involvement in the regulation of the same phenomenon in the subventricular zone (SVZ) of the lateral ventricles is not completely understood. Here, in male rats, we tested the existence of activational effects of testosterone (T) on cell proliferation in the adult SVZ. To this aim, three groups of male rats: castrated, castrated and treated with T, and controls were treated with 5-bromo-2'-deoxyuridine (BrdU) and killed after 24h. The density of BrdU-labeled cells was significantly lower in castrated animals in comparison to the other two groups, thus supporting a direct correlation between SVZ proliferation and levels of circulating T. To clarify whether this effect is purely androgen-dependent, or mediated by the T metabolites, estradiol (E2) and dihydrotestosterone (DHT), we evaluated SVZ proliferation in castrated males treated with E2, DHT and E2+DHT, in comparison to T- and vehicle-treated animals, and sham-operated controls. The stereological analysis demonstrated that E2 and T, but not DHT, increase proliferation in the SVZ of adult male rats. Quantitative evaluation of cells expressing the endogenous marker of cell proliferation phosphorylated form of Histone H3 (PHH3), or the marker of highly dividing SVZ progenitors Mash1, indicated the effect of T/E2 is mostly restricted to SVZ proliferating progenitors. The same experimental protocol was repeated on ovariectomized female rats treated with E2 or T. In this case, no statistically significant difference was found among groups. Overall, our results clearly show that the gonadal hormones T and E2 represent important mediators of cell proliferation in the adult SVZ. Moreover, we show that such an effect is restricted to males, supporting adult neurogenesis in rats is a process differentially modulated in the two sexes.

Abstract
BACKGROUND DLG5 p.R30Q has been reported to be associated with Crohn disease (CD), but this association has not been replicated in most studies. A recent analysis of gender-stratified data from two case-control studies and two population cohorts found an association of DLG5 30Q with increased risk of CD in men but not in women and found differences between 30Q population frequencies for males and females. Male-female differences in population allele frequencies and male-specific risk could explain the difficulty in replicating the association with CD. METHODS DLG5 R30Q genotype data were collected for patients with CD and controls from 11 studies that did not include gender-stratified allele counts in their published reports and tested for male-female frequency differences in controls and for case-control frequency differences in men and in women. RESULTS The data showed no male-female allele frequency differences in controls. An exact conditional test gave marginal evidence that 30Q is associated with decreased risk of CD in women (p = 0.049, OR = 0.87, 95% CI 0.77 to 1.00). There was also a trend towards reduced 30Q frequencies in male patients with CD compared with male controls, but this was not significant at the 0.05 level (p = 0.058, OR = 0.87, 95% CI 0.74 to 1.01). When data from this study were combined with previously published, gender-stratified data, the 30Q allele was found to be associated with decreased risk of CD in women (p = 0.010, OR = 0.86, 95% CI 0.76 to 0.97), but not in men. CONCLUSION DLG5 30Q is associated with a small reduction in risk of CD in women.

Abstract
This study describes the effect of parity (multiparous versus primiparous) and body condition score (BCS) at calving (<3 or > or =3; scale 1-5) on variations of BCS, body weight (BW) and metabolic profiles in Holstein cows grazing on improved pastures. Forty-two cows were studied (21 multiparous and 21 primiparous) from 2 months before to 3 months after calving. BCS, BW and milk production were measured every 2 weeks. Blood samples were taken every 2 weeks to determine total protein, albumin, urea, non-esterified fatty acids (NEFA), beta-hydroxybutyrate (BHB), cholesterol, aspartate aminotransferase (AST), calcium, phosphorus and magnesium. Primiparous cows had lower BCS during the early postpartum (PP) period and produced less milk than multiparous. In primiparous cows NEFA concentrations were higher during the early postpartum period; BHB levels were similar in both categories during this period. Primiparous cows showed a more unbalanced metabolic profile than multiparous cows, reflecting that they are recovering from the loss of BCS after calving with less success.

Abstract
The Parkin gene is responsible for about 50% of autosomal recessive juvenile parkinsonism (ARJP) and less than 20% of sporadic early onset cases. We recently mapped a novel ARJP locus (PARK6) on chromosome 1p. Linkage to PARK6 was confirmed in 8 families from 4 different European countries. These families share some clinical features with the European Parkin-positive cases, with a wide range of ages at onset and slow progression. However, features typical of ARJP, such as dystonia and sleep benefit, were not observed, making the clinical presentation of late-onset cases indistinguishable from that of idiopathic PD. The determination of the smallest region of homozygosity in one consanguineous family allowed reducing the candidate interval to 9 cM. PARK6 appears to be an important locus for ARJP in Europe.

Abstract
Mutations in the Connexin 26 (Cx26) gene have been found to account for approximately 20% of all childhood deafness. This number approaches 50% in documented recessive cases of hearing loss. Two mutations, 35delG and 167delT, account for the majority of reported mutations in this gene, but to date, more than 60 mutations have been described. No other single gene has yet been identified that contributes this significantly to the aetiology of hearing loss. Several mutations in this gene have been found to predominate in specific ethnic populations (167delT in Ashkenazi Jews and 235delC in Japanese individuals). While the majority of mutations found in Cx26 result in frame shifts and premature terminations, a number of missense mutations have also been identified. The V37I missense mutation has been reported as both a polymorphism and as a potentially disease-causing missense mutation. The present authors have identified three unrelated individuals with sensorineural hearing loss who are homozygous for this mutation. One individual is of Philippine ancestry, another is from a Chinese and Cambodian background, while the third is of Chinese ancestry, raising the possibility that this mutation may be more frequent among populations in eastern Asia.

Abstract
Nitrite concentrations in plasma were investigated in a population of migraine and cluster headache patients and a group of healthy non-headache controls. A hundred migraine patients and 69 cluster headache patients in the interictal period, and 112 controls, were studied. Significantly higher nitrite concentrations were found in migraine patients, with and without aura, and cluster headache patients, in remission and cluster phase, than in controls. These findings suggest that a basal dysfunction in the L-arginine-NO pathway may be involved in the peripheral mechanisms predisposing subjects with neurovascular headaches to individual attacks.

Abstract
The clinical features of nine patients (three women and six men) affected by PARK6-linked parkinsonism, belonging to three unrelated Italian families, are reported. The occurrence of affected men and women within one generation suggested an autosomal recessive mode of inheritance in all three families. Mean age at disease onset was 36 +/- 4.6 years; all cases except one presented with asymmetrical signs, consisting of tremor and akinesia of one upper limb or unilateral short step gait. Affected individuals had a mean age of 57 +/- 8.5 years, and average disease duration was 21 +/- 7.8 years. Parkinsonian features included benign course, early onset of drug-induced dyskinesias, and a good and persistent response to levodopa. There were no other associated features (i.e., pyramidal or cerebellar signs, dysautonomia, or diurnal fluctuations unrelated to drug treatment). Cognition was unaffected. The clinical picture was remarkably similar in all patients; no relevant family-related differences were found. PARK6 disease is a new form of early-onset parkinsonism without other atypical clinical features.

Abstract
This study characterized endometrial expression of mRNAs of oestrogen and progesterone receptors (ER, PR) and insulin-like growth factor-I (IGF-I) during the oestrous cycle. Seven Holstein heifers that showed standing oestrus on the same day (day 0) were selected and blood samples for oestradiol (E2) and progesterone (P4) determinations by RIA were taken daily until day 23. Endometrial samples were taken by transcervical biopsies on days 0, 5, 12 and 19 for mRNA determination by solution hybridization. The highest endometrial mRNA levels of ERalpha and PR were observed at oestrus and a decline was observed already at day 5, which then decreased progressively at the end of the luteal phase. IGF-I mRNA levels were higher at day 0 and 5 than at day 12. At day 19, mRNA levels of ERalpha, PR and IGF-I were the lowest in heifers that were at the end of their luteal phase (n=4), but were high again in heifers which P4 levels were basal (n=3). The temporal changes in mRNA endometrial expression of ERalpha, PR and IGF-I and their relation to the changes in steroid concentrations during the bovine oestrus cycle are described.

Abstract
The cause of Parkinson disease (PD) is still unknown, but genetic factors have recently been implicated in the etiology of the disease. So far, four loci responsible for autosomal dominant PD have been identified. Autosomal recessive juvenile parkinsonism (ARJP) is a clinically and genetically distinct entity; typical PD features are associated with early onset, sustained response to levodopa, and early occurrence of levodopa-induced dyskinesias, which are often severe. To date, only one ARJP gene, Parkin, has been identified, and multiple mutations have been detected both in families with autosomal recessive parkinsonism and in sporadic cases. The Parkin-associated phenotype is broad, and some cases are indistinguishable from idiopathic PD. In > or = 50% of families with ARJP that have been analyzed, no mutations could be detected in the Parkin gene. We identified a large Sicilian family with four definitely affected members (the Marsala kindred). The phenotype was characterized by early-onset (range 32-48 years) parkinsonism, with slow progression and sustained response to levodopa. Linkage of the disease to the Parkin gene was excluded. A genomewide homozygosity screen was performed in the family. Linkage analysis and haplotype construction allowed identification of a single region of homozygosity shared by all the affected members, spanning 12.5 cM on the short arm of chromosome 1. This region contains a novel locus for autosomal recessive early-onset parkinsonism, PARK6. A maximum LOD score 4.01 at recombination fraction .00 was obtained for marker D1S199.

Abstract
Primary torsion dystonia (PTD) is a clinically and genetically heterogeneous group of movement disorders, usually inherited in an autosomal dominant fashion with reduced penetrance. The DYT1 gene on chromosome 9q34 is responsible for most cases of early limb-onset PTD. Two other PTD loci have been mapped to date. The DYT6 locus on chromosome 8 is associated with a mixed phenotype, whereas the DYT7 locus on chromosome 18p is associated with adult onset focal cervical dystonia Several families have been described in which linkage to the known PTD loci have been excluded. We identified a large Italian PTD family with 11 definitely affected members. Phenotype was characterized by prominent cranial-cervical and upper limb involvement and mild severity. A genome-wide search was performed in the family. Linkage analysis and haplotype construction allowed us to identify a novel PTD locus (DYT13) within a 22 cM interval on the short arm of chromosome 1, with a maximum lod score of 3.44 between the disease and marker D1S2667.

Abstract
Migraine, particularly migraine with aura (MA), may be a risk factor for ischemic stroke (IS). The reasons for this association are unknown. We investigated the presence of genetic abnormalities of the protein C system in 83 MA patients, 31 IS patients, and 124 healthy controls, all aged under 45 years. We found an increased frequency of activated protein C resistance due to Arg506Gln factor V mutation, and of protein S deficiency in both disorders, with figures higher than those reported in the general population and significantly different from those found in controls. These prothrombotic genetic abnormalities may be shared risk factors in IS and MA, and may play a role in increasing the risk of cerebrovascular disease in migraineurs.

Abstract
Involvement of the cerebral serotoninergic system has been invoked to explain the origin of the pain and the vascular phenomena in migraine. To further investigate the type of cerebral serotonin receptors that may be altered in migraine, the prolactin (PRL) and cortisol responses to m-chlorophenylpiperazine (mCPP), a selective 5-HT1A,-5-HT(2A/C) receptor agonist, were monitored in 12 patients suffering from migraine without aura and in 14 matched healthy controls. Each subject underwent two challenges, one with mCPP (0.5 mg/kg) and the other with placebo (orally) using a double-blind crossover design. Anxiety level was measured by the State Trait Anxiety Inventory. Migraine patients had a greater PRL response to mCPP (p = 0.05) and greater anxiety (p < 0.01) than controls; cortisol response to mCPP did not differ suggesting that 5-HT2C receptors are normal in migraine. Augmented PRL response to mCPP could derive from 5-HT1A receptor hypersensitivity, perhaps as as a consequence of anxiety due to pain expectation. Cerebral 5-HT1A hypersensitivity could also explain the increased occurrence of migraine attacks during anxiety.

Abstract
Antigen derived peptides bound on MHC class II molecules on presenting cells stimulate specific CD4 lymphocytes that are in a naive state if antigen is given for the first time, or in a memory state if antigen has been previously encountered. In order to compare clonal heterogeneity of the human CD4+ T helper repertoire in primary vs. recall responses, we have generated T cell lines in vitro by repeated stimulation of peripheral lymphocytes with primary or with recall antigens. Clonal heterogeneity was broad in the case of recall response to tetanus toxoid or PPD, with a high frequency of specific precursors (> 100 cells/10(6) lymphocytes). In contrast, T cell lines responsive to primary antigens (HIV gp120 or HIV p66) were oligoclonal as defined by TCR V beta gene usage and by spectratyping, and the precursor frequency was low (< 2 cells/10(6) lymphocytes). Primary T cell lines generated from blood samples drawn at different times from the same donor showed that clones with identical TCR CDR3 region coding sequences were expanded, suggesting that in these individuals a large progeny derived from one single precursor is present, even though a previous encounter with the antigen was not documented. Assuming an even in vivo distribution of such cells, the presence of one precursor every 10(6) CD4 lymphocytes (within the CD4 T repertoire that comprises roughly 10(11) CD4 T cells) indicates that approximately 10(5) identical T cells from the same clonal precursor account for the primary response against the model antigens we have studied.

Abstract
Human T lymphocytes have been shown to express inhibitory natural killer cell receptors (NKR), which can down-regulate T cell antigen receptor-mediated T cell function, including cytolytic activity. In the present study, we demonstrate that CD3+NKR+ cells can be identified in HIV-infected patients. HIV-specific cytolytic activity was analyzed in five patients in whom autologous lymphoblastoid B cell lines could be derived as a source of autologous target cells. Phytohemagglutinin-activated T cell populations that had been cultured in interleukin 2 displayed HIV-specific cytotoxic T lymphocyte (CTL) activity against HIV env, gag, pol, and nef in 3 of 5 patients. Addition of anti-NKR mAb of IgM isotype could increase the specific CTL activity. Moreover, in one additional patient, HIV-specific CTL activity was undetectable; however, after addition of anti-NKR mAb such CTL activity appeared de novo. Similar results were obtained by analysis of CD3+NKR+ clones derived from two patients. These data provide direct evidence that CD3+NKR+ cells may include antigen (HIV)-specific CTLs and that mAb-mediated masking of inhibitory NKR may revert the down-regulation of CTL function.

Abstract
The naive T-helper (Th) repertoire specific for HTLV-1 envelope (env) has been examined on antigen specific T-cell lines and clones from non-immune individuals. Clonal heterogeneity was determined by analysing the T-cell receptor (TCR) Vbeta gene usage and by sequencing the hypervariable regions of the TCR genes. Fluctuations in the V beta gene usage were determined by comparing the TCR Vbeta gene profiles of T-cell lines at different times. We found that a diverse repertoire for HTLV-1 env could be triggered in vitro. Diverse Vbeta genes were used by the same line tested at different times, suggesting that clonal composition of an antigen-specific T-cell line is not constant in vitro. Clones in fact may be up- and down-regulated and clonotypes undetectable at one time point can emerge upon subsequent restimulation. Therefore evaluation of the clonal composition of a T-cell line gives a snapshot of the dominant clones at the time of analysis, and does not tell the whole picture of the antigen-specific ensemble. Furthermore, by sequencing the TCR genes, we identified clones with identical Vbeta gene usage which differed in hypervariable regions (CDR3), indicating their derivation from independent precursors and contributing to overall clonal heterogeneity. If these data can be extended to HTLV-1-infected patients studied in vivo, the Th cell repertoire specific for HTLV-1 env may prove very heterogenous, with important implications for vaccine development.

Abstract
Antigen-specific T helper cells play an important role in retroviral infections. Indeed, they provide help for B-cell activation and antibody production and for clonal expansion of cytolytic lymphocytes. Therefore, we used retrovirus-specific human T helper clones in order to define modes of antigen presentation, antigen-presenting cells and the molecular context of Th epitopes that could be exploited in the design of immunogens aimed at optimizing the Th cell response. In particular, we describe several mechanisms of receptor-mediated antigen uptake that enhance the stimulation of human T-cell clones specific for HIV and HTLV-1 antigens; we report on the differential recognition of Th epitopes depending on the molecular-viral context; we show that dendritic cells are the most efficient presenting cells and are essential for the induction of in vitro primary Th cell responses; and finally, we propose that Th cells specific for internal, conserved antigens of HIV such as reverse transcriptase, may be candidates for intrastructural help resulting in induction of envelope specific antibodies.

Abstract
CD4+ T cell lines and clones specific for human immunodeficiency virus (HIV) antigens have been generated from peripheral lymphocytes of naive individuals by priming with the envelope protein gp120, the enzyme reverse transcriptase (p66), and their synthetic peptides. T cells were tested for proliferation to proteins, to peptides, and to HIV virions. Different patterns of reaction were identified. T cells primed in vitro with the whole antigen responded to the protein, but recognition of overlapping peptides occurred with a fraction of the lines or clones. The virus was recognized by some, but not all, of the gp120- and p66-specific T cells, with an efficiency 2 logs higher than the recombinant soluble proteins on a molar basis. One T cell line specific for gp120 responded to virions presented by B cells, but not by monocytes. In contrast, T cells induced with peptides did not always respond to the proteins. Generation of T cell lines from naive individuals may be an in vitro model for T cell immunization, and the response patterns may have implications for the design of vaccines aimed at inducing a T helper response. In fact our in vitro data suggest that (a) immunization with peptides does not always induce T cells recognizing the whole protein, (b) immunization with proteins does not always induce T cells recognizing the protein in the context of the HIV virus, and (c) recognition of gp120 in the context of HIV may be dictated by the type of presenting cells.

Abstract
Cooperation between B cells specific for an antigen exposed on a viral structure and T helper (Th) cells specific for an internal antigen, as demonstrated with influenza, hepatitis B and rabies viruses, has been termed intrastructural help. Th cells specific for internal proteins of HIV, which are much less mutated than its exposed antigens, may be valuable in vaccine design against this virus. We investigated the human Th repertoire specific for the core HIV antigen reverse transcriptase (p66), and determined whether these cells could be candidate intrastructural T helpers. CD4+ T lines and clones were generated from non-immune individuals by stimulation with p66-pulsed antigen-presenting cells (APC). Specific lines were obtained with p66 from 19 out of 21 (90%) of these individuals, vs. 7 out of 29 (24%) with gp120. Diverse epitopes were recognized by different individuals, and various V beta genes were used by these clones. Clones using the same V beta genes were of diverse origin, according to VDJ region sequence. Of these lines 45% responded to p66 in the context of HIV virions. Moreover, p66-specific clones could respond to APC that had internalized HIV complexed with envelope-specific monoclonal antibodies, suggesting that p66-specific Th cells may participate in intrastructural help. These studies indicate that p66-specific Th cells are detectable in vitro in most naive individuals and exhibit clonal heterogeneity, and that the majority recognize an HIV conserved antigen. They respond to p66 following processing of whole virions and are clearly candidates for intrastructural help. If confirmed in vivo, p66 should be included among vaccine candidates investigated to optimize the anti-HIV Th response.

Abstract
Because T-helper cells are critical for immune responses in retroviral infections, CD4+ T-cell lines specific for the human T-leukemia virus type 1 (HTLV-1) envelope have been generated from peripheral T lymphocytes of nonimmune donors to study their naive repertoire. Recombinant fragments (RE1, amino acids [aa] 26-200; RE3, aa 165-307; RE5, aa 308-401; and RE6, aa 165-401) of HTLV-1 envelope, whole envelope glycoprotein, and synthetic peptides were used to induce T-cell lines. CD4+ T-cell lines specific for one or more fragments were obtained from seven of eight individuals tested. T-cell lines generated against envelope glycoprotein from five of five donors did not cross-react with the RE fragments and vice versa. The lines specific for RE and env were mapped with overlapping peptides. The lines with single peptide (narrow) specificity contained a variety of clones that used different T-cell receptor V beta genes. These data (1) suggest that most of the normal individuals carry T-helper precursors specific for epitopes on HTLV-1 envelope; (2) indicate that heterogeneity of HTLV-1 envelope-specific T cells can be detected in the naive repertoire; and (3) define optimal antigenic preparations to be used to assess cellular immunity in HTLV-1-infected individuals.

Abstract
Since 1983 we have performed percutaneous treatment of biliary lithiasis in 97 patients. Previous retrograde endoscopic procedures were incomplete or infeasible in all patients. Immediate results were excellent resulting in complete resolution of lithiasis in 89 of 97 patients (92%). In 4 patients (4%) partial success was obtained (symptoms subsided although there were nonobstructing residual stones). Percutaneous treatment failed in 1 patient (1%). Three patients died. Complications occurred in 14 of 97 patients (14%) and mortality at 30 days was 3%. Long-term results were evaluated in 71 patients who had a least a 6-month follow-up (mean 31 months and range 6-78 months). Eight of 71 patients (11%) had recurrence of stones and 7 of these were successfully retreated transhepatically. Percutaneous removal of biliary stones is efficacious because it has a high cure rate, a low complication rate, and a mortality rate that compares favorably to that of surgery even though the patients are usually older and in poorer general condition.

Abstract
4-Hydroxynonenal (HNE), a major product of the peroxidation of liver microsomal lipids, was examined for mutagenic activity at the hypoxanthine-guanine phosphoribosyltransferase locus in V79 Chinese hamster lung cells. At concentrations ranging from 10 to 45 microM, HNE induced a dose-dependent increase in the number of mutations to 6-thioguanine resistance, which reached the level of 4.7X baseline at the highest concentration tested.
