Abstract
OBJECTIVE Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a rare manifestation related to CAA, thought to be more severe. We aimed to compare the clinical and radiological outcomes of CAA-ri and non-inflammatory CAA. MATERIALS AND METHODS We retrospectively included all patients with CAA-ri from 13 French centers. We constituted a sex- and age-matched control cohort with non-inflammatory CAA and similar disease duration. Survival, autonomy and cognitive evolution were compared after logistic regression. Cerebral microbleeds (CMB), intracerebral hemorrhage, cortical superficial siderosis and hippocampal atrophy were analyzed as well as CSF biomarker profile and APOE genotype when available. Outcomes were compared using Kaplan-Meier curves and log-rank tests. RESULTS Data from 48 CAA-ri patients including 28 already reported and 20 new patients were analyzed. Over a mean of 3.1 years, 11 patients died (22.9%) and 18 (37.5%) relapsed. CAA-ri patients were more frequently institutionalized than non-inflammatory CAA patients (30% vs 8.3%, p < 0.001); mortality rates remained similar. MMSE and modified Rankin scale scores showed greater severity in CAA-ri at last follow-up. MRI showed a higher number of CMB at baseline and last follow-up in CAA-ri (p < 0.001 and p = 0.004, respectively). CSF showed lower baseline levels of Aß42 in CAA-ri than non-inflammatory CAA (373.3 pg/ml vs 490.8 pg/ml, p = 0.05). CAA-ri patients more likely carried at least one APOE ε4 allele (76% vs 37.5%, adjusted p = 0.05) particularly as homozygous status (56% vs 6.2%, p < 0.001). INTERPRETATION CAA-ri appears to be more severe than non-inflammatory CAA with a significant loss of autonomy and global higher amyloid burden, shown by more CMB and a distinct CSF profile. This burden may be partially promoted by ε4 allele.

Abstract
To assess the role of rare copy number variations in Alzheimer's disease (AD), we conducted a case-control study using whole-exome sequencing data from 522 early-onset cases and 584 controls. The most recurrent rearrangement was a 17q21.31 microduplication, overlapping the CRHR1, MAPT, STH and KANSL1 genes that was found in four cases, including one de novo rearrangement, and was absent in controls. The increased MAPT gene dosage led to a 1.6-1.9-fold expression of the MAPT messenger RNA. Clinical signs, neuroimaging and cerebrospinal fluid biomarker profiles were consistent with an AD diagnosis in MAPT duplication carriers. However, amyloid positon emission tomography (PET) imaging, performed in three patients, was negative. Analysis of an additional case with neuropathological examination confirmed that the MAPT duplication causes a complex tauopathy, including prominent neurofibrillary tangle pathology in the medial temporal lobe without amyloid-β deposits. 17q21.31 duplication is the genetic basis of a novel entity marked by prominent tauopathy, leading to early-onset dementia with an AD clinical phenotype. This entity could account for a proportion of probable AD cases with negative amyloid PET imaging recently identified in large clinical series.

Abstract
The SORL1 protein plays a protective role against the secretion of the amyloid β peptide, a key event in the pathogeny of Alzheimer's disease. We assessed the impact of SORL1 rare variants in early-onset Alzheimer's disease (EOAD) in a case-control setting. We conducted a whole exome analysis among 484 French EOAD patients and 498 ethnically matched controls. After collapsing rare variants (minor allele frequency ≤1%), we detected an enrichment of disruptive and predicted damaging missense SORL1 variants in cases (odds radio (OR)=5.03, 95% confidence interval (CI)=(2.02-14.99), P=7.49.10(-5)). This enrichment was even stronger when restricting the analysis to the 205 cases with a positive family history (OR=8.86, 95% CI=(3.35-27.31), P=3.82.10(-7)). We conclude that predicted damaging rare SORL1 variants are a strong risk factor for EOAD and that the association signal is mainly driven by cases with positive family history.

Abstract
OBJECTIVE We assessed the interest of the geriatric oncology (GO) consultation (GOC) among general practitioners (GPs). MATERIALS AND METHODS We conducted a survey among GPs whose patients had had a GOC in 2012. A questionnaire was sent to GPs. The 1st part collected GPs' characteristics including medical education in geriatrics and GO, and knowledge of GOC. The following parts concerned the GOC and included the cancer type, GOC report and care plan. RESULTS One-hundred twenty-six questionnaires corresponding to 94 GPs were collected. Concerning the GPs' characteristics, age range 50-59 (44.7%), men (62.8%) and urban practice (79.8%) were the most represented, 80.8% had no expertise in geriatrics, 60.6% knew of the existence of GOCs, and 14.9% had received medical education in GO. The most frequent cancer location was gynecological (40.7%) (82.6% were breast cancers). Of the GPs, 69.8% had received a GOC report and 92% were (very) satisfied with the delivery time. A care plan was proposed after the GOC in 83% of cases. It was satisfactory in 96.4% of cases, and applied by 74.7% of GPs. Sixteen percent of GPs were called by the GO team. The less the GP was satisfied with the GOC, the more he or she wanted phone contact (p=0.02); 94% of GPs considered the GOC (very) satisfactory. Sixty-seven percent of GPs wanted to be trained in GO. CONCLUSION Very few GPs had been trained in geriatrics and/or GO. They were mostly satisfied with GOC and expressed a wish to be trained in GO.

Abstract
We hypothesized that de novo variants (DNV) might participate in the genetic determinism of sporadic early-onset Alzheimer disease (EOAD, onset before 65 years). We investigated 14 sporadic EOAD trios first by array-comparative genomic hybridization. Two patients carried a de novo copy number variation (CNV). We then performed whole-exome sequencing in the 12 remaining trios and identified 12 non-synonymous DNVs in six patients. The two de novo CNVs (an amyloid precursor protein (APP) duplication and a BACE2 intronic deletion) and 3/12 non-synonymous DNVs (in PSEN1, VPS35 and MARK4) targeted genes from a biological network centered on the Amyloid beta (Aβ) peptide. We showed that this a priori-defined genetic network was significantly enriched in amino acid-altering DNV, compared with the rest of the exome. The causality of the APP de novo duplication (which is the first reported one) was obvious. In addition, we provided evidence of the functional impact of the following three non-synonymous DNVs targeting this network: the novel PSEN1 variant resulted in exon 9 skipping in patient's RNA, leading to a pathogenic missense at exons 8-10 junction; the VPS35 missense variant led to partial loss of retromer function, which may impact neuronal APP trafficking and Aβ secretion; and the MARK4 multiple nucleotide variant resulted into increased Tau phosphorylation, which may trigger enhanced Aβ-induced toxicity. Despite the difficulty to recruit Alzheimer disease (AD) trios owing to age structures of the pedigrees and the genetic heterogeneity of the disease, this strategy allowed us to highlight the role of de novo pathogenic events, the putative involvement of new genes in AD genetics and the key role of Aβ network alteration in AD.

Abstract
OBJECTIVES Shoulder pain and injury are common in tennis players. The precise causes for such pain remain unclear. Impingement at critical tennis positions and glenohumeral instability have never been dynamically evaluated in vivo. The purpose of this study was to evaluate the different types of impingement and stability during tennis movements. DESIGN Laboratory study. METHODS Type and frequency of impingement as well as percentage of subluxation were evaluated in 10 tennis players through a novel dedicated patient-specific measurement technique based on optical motion capture and Magnetic Resonance Imaging (MRI). RESULTS All volunteers, nine male and one female, had a clinically functional rotator cuff. MRI revealed 11 rotator cuff lesions in six subjects and six labral lesions in five subjects. Lateral subacromial, anterior subacromial, internal anterosuperior, and internal posterosuperior impingements were observed in four, three, two and seven subjects, respectively. No instability could be demonstrated in this population. CONCLUSIONS Tennis players presented frequent radiographic signs of structural lesions that could mainly be related to posterosuperior impingements due to repetitive abnormal motion contacts. This is the first study demonstrating that a dynamic and precise motion analysis of the entire kinematic chain of the shoulder is possible through a non-invasive method of investigation. This premier kinematic observation offers novel insights into the analysis of shoulder impingement and instability that could, with future studies, be generalized to other shoulder pathologies and sports. This original method may open new horizons leading to improvement in impingement comprehension.

Abstract
BACKGROUND Measuring dynamic in vivo shoulder kinematics is crucial to better understanding numerous pathologies. Motion capture systems using skin-mounted markers offer good solutions for non-invasive assessment of shoulder kinematics during dynamic movement. However, none of the current motion capture techniques have been used to study translation values at the joint, which is crucial to assess shoulder instability. The aim of the present study was to develop a dedicated patient-specific measurement technique based on motion capture and magnetic resonance imaging (MRI) to determine shoulder kinematics accurately. HYPOTHESIS Estimation of both rotations and translations at the shoulder joint using motion capture is feasible thanks to a patient-specific kinematic chain of the shoulder complex reconstructed from MRI data. MATERIALS AND METHODS We implemented a patient-specific kinematic chain model of the shoulder complex with loose constraints on joint translation. To assess the effectiveness of the technique, six subjects underwent data acquisition simultaneously with fluoroscopy and motion capture during flexion and empty-can abduction. The reference 3D shoulder kinematics was reconstructed from fluoroscopy and compared to that obtained from the new technique using skin markers. RESULTS Root mean square errors (RMSE) for shoulder orientation were within 4° (mean range: 2.0°-3.4°) for each anatomical axis and each motion. For glenohumeral translations, maximum RMSE for flexion was 3.7mm and 3.5mm for empty-can abduction (mean range: 1.9-3.3mm). Although the translation errors were significant, the computed patterns of humeral translation showed good agreement with published data. DISCUSSION To our knowledge, this study is the first attempt to calculate both rotations and translations at the shoulder joint based on skin-mounted markers. Results were encouraging and can serve as reference for future developments. The proposed technique could provide valuable kinematic data for the study of shoulder pathologies. LEVEL OF EVIDENCE Basic Science Study.

Abstract
STUDY OBJECTIVES To analyse long term effects of working conditions experienced at an advanced age, and after retirement by quantifying occupational strain, impairment, and disability to establish their interrelation. DESIGN Retrospective study. PARTICIPANTS Retired miners from The French Coal Board who had worked in the coal fields of the Loire valley. From a potential population of 507 retired miners, 350 were completely evaluated. MEASUREMENT The study examines the occupational strain experienced by each subject, measured using both auto-evaluation and evaluation by experts and the locomotion impairment and the functional independence. MAIN RESULTS A significant relation between the evaluation of occupational strain and functional independence and locomotion impairment of the low back was found and also a significant relation between locomotion impairment of the low back and the length of time spent working at the coal face. CONCLUSIONS This study confirms other studies as regards the effects of occupation on health status and on the aging process, but it goes further to show the consequences of this relation on functional independence.

Abstract
The results are reported of a field trial which was designated to demonstrate the inocuity and efficacy of the purified inactivated rabies vaccine (PVRV), produced on Vero cells by the Institut Mérieux, Lyon, France in pre- and postexposure treatment in man. Four sex and age matched groups of veterinary students and medical personnel received the vaccine. The vaccine was given according to WHO recommendations for pre- and postexposure regimens. The 82 volunteers were divided into four groups and vaccinated as follows. Group IA consisted of 27 individuals, receiving injections on days 0, 7 and 21. Group IB consisted of 29 individuals, injected on days 0, 28 and 56. Group II consisted of 16 individuals, receiving a postexposure schedule of vaccinations on days 0, 3, 7, 14, 28 and 90. Group III consisted of 10 subjects, all of whom had been previously immunized with various antirabies vaccines and received one single booster inoculation of this vaccine. Serum samples were taken on the days of vaccination and 14 days later in all groups and in addition on day 70 in group IA. Neutralizing antibodies against the rabies virus were determined in the rapid fluorescent focus inhibition test (RFFIT). In conclusion it can be stated that, regardless of the schedule of prophylactic immunization, three 0.5 ml inoculations of PVRV result in very high titres of virus neutralizing antibodies and a single vaccination in previously immunized individuals is sufficient to raise the amount of antibodies to a high level. Due to the high purity of the product the vaccine is very well tolerated by the vaccinees.

Abstract
Imuthiol is a nontoxic agent recruting and regulating T cells. Phase III studies in chronic bronchitis and bronchiectasis showed that immune functions were restored to normal, or near normal values. Cure was obtained in rheumatoid arthritis, tuberculosis and chronic infections in the elderly. Imuthiol is an effective agent for the treatment of syndromes and disease states where the underlying defect is a T-cell deficiency or dysfunction.
