Abstract
OBJECTIVE Patients with functional neurological disorder involving the motor system (eg, functional weakness, functional gait) may acutely present to the hospital for new-onset symptoms. For some, symptoms may remain severe enough at the time of hospital discharge to qualify for an inpatient rehabilitation facility stay. DESIGN Data were extracted via retrospective chart review on functional neurological disorder patients ( N = 22) admitted to an inpatient rehabilitation facility between September 2019 and May 2022. Demographic and clinical data, including admission and discharge physical and occupational therapy measurements on the Inpatient Rehabilitation Facility Patient Assessment Instrument, were recorded and analyzed. RESULTS Symptom duration was less than 1 wk for nearly two thirds of the cohort. After an approximately 2-wk length of stay, patients showed statistically significant changes in admission to discharge measures of self-care, transfers, ambulation, and balance. More than 95% of patients were able to be discharged home. The presence or absence of comorbid depression, anxiety, or posttraumatic stress disorder did not impact outcomes. CONCLUSIONS For a subset of patients with persistent motor symptoms after an acute hospital admission for a new diagnosis of functional neurological disorder, a relatively short inpatient rehabilitation facility stay was associated with significant clinical gains.

Abstract
Interdisciplinary Emergency Department/hospital-based teams represent a promising care model to improve identification of and intervention for elder mistreatment. Two institutions, Weill Cornell Medicine/NewYork-Presbyterian Hospital and the University of Colorado Anschutz Medical Campus have launched such programs and are exploring multiple strategies for effective dissemination. These strategies include: (1) program evaluation research, (2) framing as a new model of geriatric care, (3) understanding the existing incentives of health systems, EDs, and hospitals to align with them, (4) connecting to ongoing ED/hospital initiatives, (5) identifying and collaborating with communities with strong elder mistreatment response that want to integrate the ED/hospital, (6) developing and making easily accessible high-quality, comprehensive protocols and training materials, (7) offering technical assistance and support, (8) communications outreach to raise awareness, and (9) using an existing framework to inform implementation in new hospitals and health systems.

Abstract
The emergency department and hospital provide a unique and important opportunity to identify elder mistreatment and offer intervention. To help manage these complex cases, multi-disciplinary response teams have been launched. In developing these teams, it quickly became clear that social workers play a critical role in responding to elder mistreatment. Their unique skillset allows them to establish close connections with community resources, collaborate with various hospital stakeholders, support patients/families/caregivers through challenging situations, navigate the legal and protective systems, and balance patient safety and quality of life in disposition decision-making. The role of the social worker on these multi-faceted teams includes conducting a comprehensive biopsychosocial assessment, helping to develop a safe discharge plan, and making appropriate referrals, among other responsibilities. Any institution considering developing a multi-disciplinary program should recognize the critical importance of social work.

Abstract
Spectrally incoherent laser pulses with sufficiently large fractional bandwidth are in demand for the mitigation of laser-plasma instabilities occurring in high-energy laser-target interactions. Here, we modeled, implemented, and optimized a dual-stage high-energy optical parametric amplifier for broadband, spectrally incoherent pulses in the near-infrared. The amplifier delivers close to 400 mJ of signal energy through noncollinear parametric interaction of 100-nJ-scale broadband, spectrally incoherent seed pulses near 1053 nm with a narrowband high-energy pump operating at 526.5 nm. Mitigation strategies for high-frequency spatial modulations in the amplified signal caused by index inhomogeneities in the Nd:YLF rods of the pump laser are explored and discussed in detail.

Abstract
BACKGROUND: Emerging research supports a primary role for rehabilitation therapy alongside psychoeducation and psychotherapy in the treatment of functional neurological disorder (FND). OBJECTIVE: While consensus recommendations for physical therapists, occupational therapists, and speech and language pathologists treating FND have been published, specific recommendations for multidisciplinary FND care delivered on an inpatient rehabilitation unit are yet to be established. METHODS: This report describes one inpatient rehabilitation facility’s efforts to design and implement a clinical pathway for patients with acute-onset motor FND—patients recently hospitalized for work-up of new neurological symptoms subsequently deemed functional. RESULTS: Detailed descriptions on defining admission criteria and delivering consensus- and evidence-based multidisciplinary inpatient rehabilitation are provided. CONCLUSIONS: In the context of prospective research studies, considerably more work is needed to delineate the optimal duration and intensity of inpatient rehabilitation treatment for the management of patients with motor FND.

Abstract
BACKGROUND: Higher levels of care in the form of intensive rehabilitation may be appropriate for select patients with a diagnosis of functional motor disorder (FMD). Intensive rehabilitation, as delivered through an outpatient day program or through admission to an inpatient rehabilitation facility, can offer a greater frequency and variety of integrated clinical services than most lower levels of care. OBJECTIVE: Higher levels of rehabilitation for FMD have not yet been well characterized in the literature. In this article, we will focus on the population of FMD patients who begin receiving care in the outpatient setting. METHOD: In this review, we describe a range of options for higher levels of FMD care, evaluate the supporting literature, and weigh the pros and cons of each approach. Several specific examples of intensive rehabilitation programs in the United States will be described. Finally, we will consider existing health systems barriers to each of these outpatient and inpatient higher levels of care. RESULTS: Within a stepped model of care, intensive outpatient day-programs and inpatient rehabilitation may be considered for individuals who present with complex, refractory motor deficits from FMD. For appropriately selected patients, a growing body of literature suggests that time-limited, goal-oriented intensive rehabilitation may provide an effective treatment avenue. CONCLUSION: It remains to be determined whether treatment in intensive care settings, while more costly in the short term, could lead to greater cost savings in the long term. The prospect of telemedicine rehabilitation for FND in terms of efficacy and cost also remains to be determined.

Abstract
We discovered a highly virulent variant of subtype-B HIV-1 in the Netherlands. One hundred nine individuals with this variant had a 0.54 to 0.74 log10 increase (i.e., a ~3.5-fold to 5.5-fold increase) in viral load compared with, and exhibited CD4 cell decline twice as fast as, 6604 individuals with other subtype-B strains. Without treatment, advanced HIV-CD4 cell counts below 350 cells per cubic millimeter, with long-term clinical consequences-is expected to be reached, on average, 9 months after diagnosis for individuals in their thirties with this variant. Age, sex, suspected mode of transmission, and place of birth for the aforementioned 109 individuals were typical for HIV-positive people in the Netherlands, which suggests that the increased virulence is attributable to the viral strain. Genetic sequence analysis suggests that this variant arose in the 1990s from de novo mutation, not recombination, with increased transmissibility and an unfamiliar molecular mechanism of virulence.

Abstract
Cycling is an important form of exercise, recreation, and transportation. Following traumatic brain injury, the benefits of cycling for health, fitness, and community mobility must be considered alongside potential risk for recurrent injury. In addition to medical concerns and exercise tolerance, key domains include motor function, attention, and visuospatial and executive function, which have previously been explored with regard to driving. Cycling skill is a combination of cognitive and motor function, and can be trained with appropriate education and intervention. We discuss the relationship of brain injury rehabilitation to specific features of cycling, including case studies.

Effect of suramin on urinary excretion of diabetes-induced glomerular and tubular injury parameters in rats. Biomed Pharmacother 2021; 139:111683.

Abstract
Diabetes mellitus causes changes in metabolism of extracellular nucleotides acting through P2 receptors (P2Rs). This affects renal function and may lead to glomerular and tubular disturbances. We measured urinary excretion of nucleotides (ATP, ADP, AMP, UTP, UDP, UMP) in streptozotocin-induced diabetic rats (65 mg/kg, i.p., day 0) and the effects of P2Rs' blockade by suramin (10 mg/kg, i.p., days +7, +14) on glomerular P2×7R expression and urinary excretion of glomerular (albumin, nephrin) and tubular (KIM-1, NGAL) injury markers, electrolytes, and oxidative stress markers (TBARS, 8-OHdG). Concentrations of nucleotides, specific proteins, electrolytes, and oxidative stress markers in 24-h urine samples collected in metabolic cages at days -1, +6 and +20 were measured using ion-paired reversed-phase HPLC, immunoenzymatic and fluorometric methods, and flame photometry, respectively. Expression of KIM-1 and P2×7R was examined by immunohistochemistry or immunoblotting. Diabetes was associated with increased urinary excretion of ATP, ADP, UTP, UDP and glomerular P2×7R expression. Suramin attenuated P2×7R expression but did not affect urinary excretion of nucleotides. Urinary excretion of albumin, nephrin, NGAL, and 8-OHdG were increased in diabetic rats and were not affected by suramin. TBARS was higher in diabetic rats and suramin attenuated the excretion dynamics in this group. KIM-1 excretion was higher in diabetic rats and suramin further increased excretion of KIM-1 in both diabetic and non-diabetic rats. Furthermore, suramin attenuated the diabetes-induced natriuresis and kaliuresis. It is possible that suramin affects both glomerular and tubular functions in diabetic rats.

Exosomes derived from mesenchymal stem cells improved core symptoms of genetically modified mouse model of autism Shank3B. Mol Autism 2020; 11:65.

Abstract
BACKGROUND Partial or an entire deletion of SHANK3 are considered as major drivers in the Phelan-McDermid syndrome, in which 75% of patients are diagnosed with autism spectrum disorder (ASD). During the recent years, there was an increasing interest in stem cell therapy in ASD, and specifically, mesenchymal stem cells (MSC). Moreover, it has been suggested that the therapeutic effect of the MSC is mediated mainly via the secretion of small extracellular vesicle that contains important molecular information of the cell and are used for cell-to-cell communication. Within the fraction of the extracellular vesicles, exosomes were highlighted as the most effective ones to convey the therapeutic effect. METHODS Exosomes derived from MSC (MSC-exo) were purified, characterized, and given via intranasal administration to Shank3B KO mice (in the concentration of 107 particles/ml). Three weeks post treatment, the mice were tested for behavioral scoring, and their results were compared with saline-treated control and their wild-type littermates. RESULTS Intranasal treatment with MSC-exo improves the social behavior deficit in multiple paradigms, increases vocalization, and reduces repetitive behaviors. We also observed an increase of GABARB1 in the prefrontal cortex. CONCLUSIONS Herein, we hypothesized that MSC-exo would have a direct beneficial effect on the behavioral autistic-like phenotype of the genetically modified Shank3B KO mouse model of autism. Taken together, our data indicate that intranasal treatment with MSC-exo improves the core ASD-like deficits of this mouse model of autism and therefore has the potential to treat ASD patients carrying the Shank3 mutation.

Molecular machinery providing copper bioavailability for spermatozoa along the epididymial tubule in mouse. Biol Reprod 2020; 100:1505-1520.

Abstract
Progressive functional maturation of spermatozoa is completed during the transit of these cells through the epididymis, a tubule structure connecting a testicle to a vas deferens. Epididymal epithelial cells by means of their secretory and absorptive functions determine a highly specialized luminal microenvironment containing multiple organic and inorganic components. The latter include copper ions, which due to their redox properties are indispensable for critical homeostatic processes occurring in spermatozoa floating in different part of epididymis but can be potentially toxic. Main purpose of our study was to determine epididymal region-dependent expression and localization of copper transporters ensuring a tight control of copper concentration in epididymal fluid. We also aimed at identifying proteins responsible for copper uptake by spermatozoa and verifying whether this process is coordinated with copper supply to superoxide dismutase 1 (SOD1), a copper-dependent antioxidant enzyme. Our study identifies two ATPases-ATP7A, ATP7B and Slc31a1, major copper importers/exporters depending on their differential expression on epididymal polarized epithelial cells of the caput, corpus, and cauda. Next, ceruloplasmin seems to be a chief protein transporting copper in the epididymal fluid and providing this biometal to spermatozoa. The entry of copper to germ cells is mediated by Slc31a1 and is correlated with both expressions of copper chaperone for superoxide dismutase (CCS), copper chaperone directly providing copper ions to SOD1 and with the expression and activity of the latter. Our results outline a network of cooperating copper binding proteins expressed in epididymal epithelium and in spermatozoa that orchestrate bioavailability of this microelement for gametes and protect them against copper toxicity.

Abstract
The fortification of various types of food with minerals is often undertaken without consideration of either their bioavailability or the potential nutrient-nutrient interactions resulting from their use. Stable isotopes provide a safe and accessible method of resolving these issues by providing the proper evidence in each case. They must be conducted according to strict safety and ethical guidelines and may be readily conducted in a field setting. Clinical studies in children enable researchers, policymakers, and food manufacturers to obtain the data necessary to determine the best way to fortify specific foods and beverages, in order to optimally enhance the nutritional health of growing children. We have shown the utility of this approach in studies in both developing countries and in the United States.

Abstract
INTRODUCTION Femoral nerve block (FNB) is considered as a major advance in anterior cruciate ligament (ACL) reconstruction as it reduces the need for parenteral opioids. However, the incidence of transient or even permanent neurological deficits due to the FNB is estimated at 1.94% after knee surgery. The primary objective of this study was to compare local infiltration analgesia (LIA) to FNB during ACL reconstruction procedures. The study hypothesis was that LIA was not less effective than FNB on early postoperative pain. PATIENTS AND METHODS A retrospective analysis of data collected prospectively in the FAST cohort included a series of continuous patients who underwent primary repair for isolated ACL with a hamstring graft in 2013-2014. Changes in our anesthesia practices over time allowed us to form three successive groups: Group 1 - FNB, Group 2 - FNB+LIA, Group 3 - LIA only. Ultrasound-guided FNB was done pre-operatively. The LIA was done at the end of the procedure by the surgeon with systematic infiltration of all skin incisions and the hamstring donor site; no intra-articular injections were performed. The primary endpoint was the average early postoperative pain (Days 0-3) described by the patient on a visual analogue scale (0-10). Sample size calculation pointed to 36 subjects being needed per group for a non-inferiority study. RESULTS The study involved 126 patients: G1=42, G2=38, G3=46. The patients were comparable at enrolment. The average early postoperative pain levels were 3.1±2.4, 2.8±2.0 and 2.5±2.2, respectively (P=0.66). A trend toward higher intake of tramadol was noted in the LIA group on D0 to D3, with a significant trend test on Day 1 (P=0.03) and Day 2 (P=0.02). CONCLUSION After reconstruction of isolated ACL tears with a hamstring graft, FNB is not more effective than LIA on patients' early postoperative pain. Patients who received a FNB consumed significantly less opioid-like analgesics. LEVEL OF EVIDENCE III - Prospective, comparative, non-randomized study.

Abstract
BACKGROUND Some surgical procedures are rarely done on an outpatient basis. The primary objective of this study was to assess the safety of outpatient surgical shoulder stabilisation using the Latarjet procedure. HYPOTHESIS The Latarjet procedure is safe when performed on an outpatient basis provided the patients are managed according to a specifically designed programme starting at the decision to undergo surgery and ending at the end of the early postoperative period. PATIENTS AND METHODS Consecutive patients with unidirectional anterior shoulder instability managed in 2013-2014 by primary open, minimally invasive surgery involving coracoid process transfer as described by Latarjet was included prospectively. One of the surgeons routinely offered outpatient surgery to patients who met none of the usual exclusion criteria (age>60years, ASA 3-4, and long distance from home to hospital). Standardised protocols were applied for anaesthesia and analgesia. The primary evaluation criterion was failure of the admission modality, defined as inpatient admission of a patient after outpatient surgery either without prior discharge or within 1week after discharge. Secondary evaluation criteria were early postoperative symptoms and functional outcomes after at least 1year. All self-reported criteria were entered online by the patients. RESULTS Of 46 included patients, 17 had outpatient surgery and 29 inpatient surgery. There were 41 males and 5 females, with a mean age of 25.3±6.4years. No significant baseline differences were found between the two groups. None of the outpatients required inpatient admission or readmission. No postoperative complications were recorded. After a mean follow-up of 18.5±5.2months, the two groups showed no significant differences for return to sports, apprehension, avoidance behaviours, or functional outcomes. Most patients were satisfied with their management and outcomes. CONCLUSION No serious adverse events were recorded in this first French prospective evaluation of the safety of open, minimally invasive shoulder stabilisation by the Latarjet procedure performed on an outpatient basis. Thus, in selected patients, the risks of outpatient surgery are similar to those of inpatient surgery. LEVEL OF EVIDENCE III, prospective, comparative, non-randomised study.

Abstract
INTRODUCTION Kinesio-Taping(®) (K-Tape) is used in sports traumatology with the aim of reducing pain and improving blood and lymph circulation. The main objective of the present study was to assess the efficacy of K-Tape on early postoperative pain after anterior cruciate ligament (ACL) reconstruction. The study hypothesis was that K-Tape significantly decreases pain. METHOD A prospective non-randomized comparative study was conducted in 2013-2014 and included all patients who underwent primary ACL reconstruction by hamstring graft. Analgesia was standardized. Two groups, "K-Tape" and "controls", were formed according to the days on which the study physiotherapist was present. The K-Tape compression/decompression assembly was applied immediately postoperatively and maintained for 3days. Patients filled out online questionnaires. The main assessment criterion was mean postoperative pain (D0-D3) on a 0-to-10 scale. Secondary criteria were analgesia intake on the three WHO levels, awakening during the night of D0 due to pain, signs of postoperative discomfort, and patient satisfaction. RESULTS Sixty patients (30 per group) were included, 57 of whom could be assessed: 28 K-Tape, 29 controls; 44 male, 13 female; mean age, 30.9±8.9 years. At inclusion, the two groups were comparable. There was no significant difference in mean (D0-D3) knee pain intensity: 3.8±2.2 for K-Tape, and 3.9±2 for controls (P=0.93). Analysis of variance (ANOVA) found no significant intergroup difference in evolution of pain (P=0.34). There were no other significant differences on the other assessment criteria. CONCLUSION K-Tape showed no efficacy on early postoperative pain following ACL reconstruction. LEVEL OF EVIDENCE III; prospective non-randomized comparative study.

Abstract
PURPOSE The aim of this study was to translate, adapt and validate in French the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI), a 12-item English language scale assessing the psychological impact of returning to sports after ACL reconstruction. METHODS The ACL-RSI scale was forward and back translated, cross-culturally adapted and validated using international guidelines. The study population included all patients who were active in sports and underwent primary arthroscopic ACL reconstruction. The control group included subjects with no history of knee trauma. At the 6-month follow-up, the study population completed the ACL-RSI scale twice within 3-4 days, Knee injury and Osteoarthritis Outcome Score (KOOS) and subjective International Knee Documentation Committee (IKDC) scores. Statistical tests assessed the construct validity, discriminant validity, internal consistency, reliability and feasibility of the ACL-RSI scale. RESULTS Ninety-one patients with ACL tears and 98 control subjects were included: mean age 31.7 ± 8.1 and 21.8 ± 2, respectively. The ACL-RSI scores were correlated with all KOOS sub-categories (r = 0.22-0.64, p < 0.05) as well as the subjective IKDC score (r = 0.42, p < 0.00001). The mean scores of the study and control groups were significantly different (62.8 ± 19.4 vs. 89.6 ± 11.5, p < 0.00001), and scores were significantly better in patients who returned to the same sport (72.1 ± 21.4 vs. 60.3 ± 18.1, p = 0.008). Internal consistency was high (α = 0.96). Test-retest reproducibility was excellent: ρ = 0.90 (0.86-0.94), p < 0.00001. Administration time was 1.32 ± 0.7 mn, and all items were answered. CONCLUSION This study showed that the cross-cultural adaptation of the English version of the ACL-RSI was successful and validated in a French-speaking population. The discriminant capacity of the scale between patients who underwent reconstruction and healthy subjects was confirmed. LEVEL OF EVIDENCE II.

Postoperative discomfort after outpatient anterior cruciate ligament reconstruction: a prospective comparative study. Orthop Traumatol Surg Res 2015; 101:163-6. [PMID: 25666422 DOI: 10.1016/j.otsr.2014.07.036] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2014] [Revised: 07/16/2014] [Accepted: 07/30/2014] [Indexed: 02/02/2023]
Abstract
INTRODUCTION The principal objective of the present study was to compare rates of postoperative discomfort after anterior cruciate ligament (ACL) reconstruction between inpatient (In) and outpatient (Out) management. PATIENTS AND METHOD A single-surgeon non-randomized prospective comparative study included patients undergoing primary surgery for isolated ACL tear by short hamstring graft in 2012-13. The Out group comprised patients eligible for and consenting to outpatient surgery and the In group, those not eligible or not consenting. The principal assessment criterion was onset of at least 1 symptom of postoperative discomfort (SPD): anxiety, nausea and vomiting, malaise, vertigo or stomach pain, between postoperative days 0 and 3. Secondary assessment criteria were difficulty in getting to sleep, getting up during the night, regular walking or going out, number of episodes of knee pain and waking because of pain. All criteria were assessed on-line by the patient. RESULTS One hundred and thirty-three patients filled out the questionnaire, 70 in the Out group and 63 in the In group; 42 females, 91 males; mean age, 30±9 years. Between D0 and D3, the proportion of patients with ≥l SPD was comparable between groups (Out 37% vs In 41%, P=0.62). Out-group patients had significantly less difficulty sleeping the first postoperative night (P=0.01), got up significantly more often during the first night after surgery (P<0.0001), more often walked regularly on day 1 (P=0.03), and were significantly less often woken by pain during the first night (P=0.003). Risk factors for SPD were female gender (OR=4.8±1.9) and postoperative complications (OR=3.8±2.5). CONCLUSION Patients undergoing ACL reconstruction on an outpatient basis did not show more symptoms of postoperative discomfort than those managed as conventional inpatients.

Abstract
INTRODUCTION The main objective of this study was to assess the feasibility of outpatient surgery in anterior cruciate ligament (ACL) reconstruction. We hypothesized that if the patient underwent the procedure within a dedicated organization, safety would be ensured. PATIENTS AND METHODS A non-randomized, prospective, comparative, single-operator study conducted in 2012-2013 included all patients undergoing first-line surgery for ACL arthroscopic reconstruction using a short hamstring graft. The outpatient group (OP) included patients who were eligible for outpatient surgery and provided consent; the conventional hospitalization group (CH) comprised those patients not suitable for outpatient surgery and those who refused it. The main evaluation criterion was failure of the admission modality defined as hospitalization of a patient who had undergone outpatient surgery or rehospitalization in the first week after discharge. The secondary evaluation criteria were the rate of postoperative complications, postoperative pain, use of analgesics, and patient satisfaction. A total of 138 patients were included: 71 in the OP group and 67 in the CH group, with a mean age of 29.6±9 years. Twenty-nine percent of the patients refused outpatient surgery. In the CH group, the mean hospital stay lasted 2.7±0.8 days. RESULTS One patient in the OP group was hospitalized with localized bleeding and there were no rehospitalizations. Six early postoperative complications were noted in each group. The mean postoperative pain on D0-D4 and patient satisfaction were similar in the two groups. CONCLUSION This prospective study encountered no serious events after outpatient ACL reconstruction surgery. In a selected population, the risks are comparable to those in conventional hospitalization. LEVEL OF EVIDENCE Level III, comparative study.

Abstract
It is believed that the most effective method of treatment in schizophrenia is pharmacotherapy, in particular, the use of atypical neuroleptics like aripiprazole (ARI) and olanzapine (OLA). Moreover, studies of many authors have shown that enriched living conditions and tobacco smoke exposure can also affect the cognitive functions that are disturbed in the course of schizophrenia. The aim of the study was to find whether tobacco smoke and enrichment living conditions have the influence on cognitive functions in the newborn offspring of prenatally stressed rats and whether drugs such as ARI (1.5 mg/kg intraperitoneally (i.p.)) and OLA (0.5 mg/kg ip) in single and chronic treatment modify those functions (Morris water maze). The study (in the same conditions) also analyses immobility time (Porsolt test) and motor activity of animals that received ARI and OLA. It has been shown that ARI and OLA as well as enriched environment reduce cognitive function disorders and modify cognitive functions in rats exposed to tobacco smoke. In turn, current research has shown that nicotine has increased cognitive function disorders compared to the previous study (animals without tobacco smoke exposure).

Sensitivity and specificity of bell-hammer tear as an indirect sign of partial anterior cruciate ligament rupture on magnetic resonance imaging. Knee Surg Sports Traumatol Arthrosc 2014; 22:1112-8.

Abstract
PURPOSE The main purpose of this study was to evaluate the usefulness of the bell-hammer sign in the diagnosis of partial tears of the anterior cruciate ligament (ACL) of the knee on MRI. METHODS A retrospective study was performed including all patients who underwent ACL reconstruction for partial or complete tears from 2008 to 2009. The diagnosis of partial or complete ACL tears was based on the appearance of the ligament bundles and the signal quality on MRI. On arthroscopy, which is considered the gold standard, each bundle was classified as normal, partially or completely torn depending on the extent of the rupture and the quality of the remaining fibres. The study included 312 patients, 83 women and 229 men (mean age 33.3 ± 19.6 years). A diagnosis of a tear was made in all patients on preoperative MRI. Arthroscopy did not show any normal ACL, 247/312 (79.2 %) complete tears and 65/312 (20.8%) partial tears, 50/65 (76.9%) on the anteromedial bundle (AM) and 15/65 (23.1%) the posterolateral bundle. RESULTS The bell-hammer sign was found on MRI in 13/312 patients (4.5%). It involved 9/65 (13.8%) partial tears, all in the AM bundle, and 4/247 (1.6%) complete tears, significantly more frequent in cases of partial rupture (p < 0.0001). MRI diagnosed a partial tear in 15/65 cases without the bell-hammer sign (sensitivity CI 95% = 23.1 ± 10%, specificity CI 95% = 95.9 ± 2.5%) and with the bell-hammer sign in 23/65 cases (sensitivity CI 95% = 35.4 ± 11%, specificity CI 95% = 93.9 ± 3%). The association of the bell-hammer sign with conventional radiological diagnostic criteria has improved diagnosis performance of MRI for partial tears but not significantly (ns). CONCLUSION The most important interest of the bell-hammer sign in the day-to-day clinical work is to suggest partial tears on MRI. It aids making a diagnosis, but its absence does not exclude partial ACL rupture. LEVEL OF EVIDENCE Diagnostic study, Level II.

Abstract
Noninvasive transcranial direct current stimulation (tDCS) and methylphenidate (MP) are associated with motor recovery after stroke. Based on the potentially complementary mechanisms of these interventions, we examined whether there is an interactive effect between MP and tDCS. In this preliminary study, we randomized subacute stroke subjects to receive tDCS alone, MP alone or combination of tDCS and MP. A blinded rater measured safety, hand function, and cortical excitability before and after treatment. None of the treatments caused any major or severe adverse effects or induced significant differences in cortical excitability. Analysis of variance of gain score, as measured by Purdue pegboard test, showed a significant between-group difference (F(2,6)=12.167, p=0.008). Post hoc analysis showed that the combination treatment effected greater Purdue pegboard gain scores than tDCS alone (p=0.017) or MP alone (p=0.01). Our preliminary data with nine subjects shows an interesting dissociation between motor function improvement and lack of motor corticospinal plasticity changes as indexed by transcranial magnetic stimulation in subacute stroke subjects.

Primary arthroscopic synovectomy for pigmented villo-nodular synovitis of the knee: recurrence rate and functional outcomes after a mean follow-up of seven years. Orthop Traumatol Surg Res 2013; 99:937-43.

Abstract
BACKGROUND Pigmented villo-nodular synovitis (PVNS) is an uncommon proliferative condition of the synovial membrane that chiefly affects the knee. Arthroscopic synovectomy may carry lower morbidity rates but higher recurrence rates than open synovectomy. Here, our objective was to evaluate recurrence rates and functional outcomes after primary arthroscopic synovectomy for PVNS of the knee. HYPOTHESIS Primary arthroscopic synovectomy preserves knee function while producing low recurrence and complication rates. MATERIALS AND METHODS We retrospectively included consecutive patients with histologically documented PVNS managed with primary arthroscopic synovectomy at two centres between 1998 and 2011. Twenty-three patients, 13 men and 10 women with a mean age of 41 ± 12 years, were reviewed including 16 patients with nodular and 7 with diffuse form of this disease. Patients with localized disease underwent partial synovectomy and those with diffuse disease complete synovectomy followed by chemical synovectomy of any residual lesions. The primary outcome measure was recurrence. Secondary outcome measures were the Tegner-Lysholm and Ogilvie-Harris scores. RESULTS Follow-up data were obtained after a mean of 7 ± 4 years in 21 patients (14 with nodular and 7 with diffuse disease), of whom 2 had recurrences, after 2 and 5 years, respectively. At last follow-up, neither patient had any evidence of recurrence. The mean Tegner-Lysholm score was significantly improved (from 68 ± 10 to 90 ± 8, P=0.0004) and the mean Ogilvie-Harris score indicated excellent function (11 ± 1). DISCUSSION Primary arthroscopic synovectomy ensures satisfactory control of PVNS while preserving knee function. A full recovery remains possible even in patients with diffuse disease. In the event of a recurrence, open synovectomy can be performed.

Abstract
INTRODUCTION Women run a 4-8-fold greater risk of anterior cruciate ligament (ACL) tear than men, and especially during the pre-ovulation stage of their cycle. The main study objective was to describe the distribution of ACL lesions according to menstrual cycle in a large population of female recreational skiers. MATERIALS AND METHODS A prospective study was conducted during the 2010-11 ski season on women sustaining ACL tear during skiing. Patients filled out a questionnaire during consultation with the mountain physician, including date of last menstrual period (LMP) and contraceptive method. Fifty-seven of the 229 patients with diagnosed ACL tear were excluded from analysis, 41 being post-menopausal (mean age, 47 ± 9 years), and 16 having irregular cycles or LMP>30 days. One hundred and seventy-two patients (mean age, 34 ± 8.7 years) were thus included. RESULTS Fifty-eight women (33.72%) were in follicular phase, 63 (36.63%) in ovulatory phase and 51 (29.65%) in luteal phase; difference with respect to the theoretic distribution regardless of menstrual phase was highly significant: χ(2)=48.32; P=0.00001. Fifty-three of the 172 women (30.8%) were taking oral contraceptives. ACL tear was 2.4-fold more frequent in pre-ovulatory than post-ovulatory phase, whether in women using oral or other contraceptives: 85/119 (71.4%) vs. 36/53 (67.9%); P=0.64. CONCLUSION ACL tear risk in skiing in women is not constant over the menstrual cycle, being 2.4-fold more frequent in pre-ovulatory (follicular and ovulatory) than post-ovulatory phase (luteal). Oral contraception seems not to exert any protective effect. LEVEL OF EVIDENCE Level IV. Retrospective cohort study.

Abstract
The surgical technique for repair of acute proximal hamstring tears is relatively recent. Installation of the patient is critical. The approach is either vertical under the gluteal fold in case of a complete tear with tendon retraction of more than 6 cm, or horizontal in the gluteal fold for retraction of less than 6 cm or for partial tears. After identification and neurolysis of the sciatic nerve, transosseous tendon reinsertion is performed with three or four metal or resorbable suture anchors. A rigid brace keeping the leg at 30° of flexion is worn for few days, then replaced by an articulated knee brace for 45 days, which limits extension but allows full flexion. Rehabilitation is begun early. Thirty-four patients underwent surgery for acute proximal hamstring tear and received this treatment. All of the athletic patients were able to return to their pre-injury activities after a mean 5.7 ± 1.6 months (2.3-9.3 months).

Abstract
PURPOSE Although the treatment of choice for acute proximal hamstring ruptures is now surgical repair, this technique is relatively new and requires further evaluation. Our hypothesis was that patients return to sports at the same level after surgical repair as before injury. METHODS From 2002 to 2011, a prospective observational study including 34 patients, mean age 39.3 ± 11.4 years old underwent surgical repair of an acute proximal hamstring rupture. Surgical, rehabilitation and follow-up protocols were standardized. Mean follow-up was 27.2 ± 22.9 months and there were no lost to follow-up. The primary outcome was the level of activity on the UCLA and Tegner scores. RESULTS The mean UCLA score was 9.1 ± 1.3 before injury and 8.7 ± 1.7 at the final follow-up (p = 0.03). The median Tegner activity level was 6 (range, 4-10) before injury and 6 (range, 3-10) at the final follow-up (p = 0.05). The two scores were correlated (r = 0.76, p = 0.00001). Patients returned to sports within a mean 5.7 ± 1.6 months, at the same level in 27 patients (79.4 %) and at a lower level in 7 patients (20.6 %). The average hamstring/quadriceps ratio at 240°/second was 54.7 ± 8.6 % which was positively correlated to the level of activity on the UCLA score (r = 0.49, n.s.). The level of satisfaction was related to their level of activity at the final follow-up (p = 0.03). CONCLUSION Although surgical repair of acute proximal hamstring ruptures has significantly improved the functional prognosis of patients it remains a serious condition that can compromise future sports activities.

Abstract
PURPOSE To compare the performance of 3D-FSE-Cube MRI to arthroscopy, the reference test for the diagnosis of partial anterior cruciate ligament (ACL) tears. METHODS A retrospective study was performed including all patients who underwent surgery for an ACL tear in our Sports Surgery Unit from January 2008 to December 2009. All patients underwent a preoperative MRI, conventional 2D or 3D-Cube. The diagnosis of a partial tear was based on the appearance of the ligament bundles and signal quality on MRI, and on the continuity of the fibers on arthroscopy and the quality of the remaining ligament. Sixty-four of the 312 included patients underwent MRI 3D-Cube and 248 conventional 2D-MRI. The series included 82 women and 223 men, mean age 33.3 ± 19.6 years. Arthroscopy did not reveal any normal ACL, 247/312 (79.2 %) complete tears, and 65/312 (20.8 %) partial tears, with 50/65 (76.9 %) involving the anteromedial bundle and 15/65 (23.1 %) the posterolateral. RESULTS The results of MRI 3D-Cube were as follows: sensitivity 95 % CI = 62.5 ± 23.7 %, specificity 95 % CI = 93.7 ± 6.9 %, likelihood ratio LR(+) = 9.9, LR(-) = 0.4 and accuracy 85.9 %. Results of conventional 2D-MRI were as follows: sensitivity 95 % CI = 10.2 ± 8.5 %, specificity 95 % CI = 96.5 ± 2.5 %, LR(+) = 2.9, LR(-) = 0.9 and accuracy 79.4 %. The diagnostic performance of MRI 3D-Cube was better than conventional 2D-MRI. CONCLUSION The diagnostic performance of MRI 3D-Cube in partial ACL tears was good and significantly better than conventional 2D-MRI. The likelihood of having a positive test was 9.9 times higher in a patient with a partial tear. A negative result did not exclude this diagnosis.

Abstract
BACKGROUND Studies of orthostatic changes in cutaneous micro-perfusion have yielded conflicting results, likely from imprecision of legacy equipment. METHODS Postural flow changes in the femoral vessels and cervical carotids were measured in healthy normal adults using duplex equipment. Nutrient skin flow was measured using Hyperspectral imager (OxyVu-2™), a newer non-touch measurement technology. RESULTS There are regional variations in cutaneous capillary density, sparse in the abdomen but richer in the forehead and ankle. Orthostatic microvascular congestion displays regional variations reflective of the non-linear pressure-volume relationship in thin walled vessels. There is profound cutaneous deoxygenation (≈40% reduction) in the lower body starting at the level of the umbilicus and involving all levels below, in the erect posture; upper body is unaffected. Quantitative regional flow is preserved however, with an increase in pulse rate despite a velocity decrease in the femoral vessels. Increasing the arterio-venous gradient by calf-emptying maneuvers resulted in little improvement in cutaneous oxygenation unable to overcome the powerful orthostatic vasoconstriction. CONCLUSION There is intense orthostatic vasoconstriction and cutaneous deoxygenation of the lower limbs to a degree not previously suspected. This powerful mechanism may be relevant to an understanding of dysvascular syndromes, particularly those with strong orthostatic features.

Abstract
The notes of all HIV patients in Sheffield, registered at the Department of Genitourinary Medicine at the Royal Hallamshire Hospital, who had initiated HAART in 2005 and 2006, were audited. The aim was to determine what percentage of these patients acquired an undetectable viral load within 24 weeks and whether this was greater than 75% in accordance with the BHIVA guidelines. Twenty-nine (78.4%) of the 37 patients who were initiating treatment for the first time had an undetectable viral load after 24 weeks.

Abstract
OBJECTIVE The mechanism by which low dose methotrexate (MTX, the gold standard treatment for rheumatoid arthritis) exerts its anti-inflammatory effect in rheumatoid arthritis (RA) patients is still debated. Lately, the MTX immunosuppressive effect has been related to apoptosis, especially in active RA patients, with ROS involvement. METHODS In the present research we investigated MTX oxidative effect and its ability to modulate immune balance in active versus non-active RA patients. RESULTS Our results show that MTX induces IL-10 secretion (a TH2 cytokine) and significantly reduces TH1 profile in Peripheral Mononuclear Cells (PMNC) derived from active RA patients (n=28). Additionally, we found that MTX modulates the immune status towards TH2 dominance by decreasing the IL-12R and the CXCR3 receptors typical for the TH1 population. Moreover, MTX was found to inhibit the production of nitric oxide (NO) in these patients, a phenomenon that might contribute to MTX action toward cytokine homeostasis. A significant correlation was found between MTX IL-10 induction and NO inhibition in active RA patients. CONCLUSION Our data suggest that, in active RA patients, apoptosis induction by MTX may be primarily due to IL-10 production via modulation of oxidative stress, which may restore the critically important immune balance. These findings may contribute to determining which group of RA patients may better respond to MTX therapy.

Abstract
BACKGROUND Lower limb muscle power impairments are modifiable factors underlying mobility limitations in older adults. This study examined relationships between upper and lower limb muscle power and their role in predicting mobility performance among community-dwelling older adults. METHODS A cross-sectional analysis was conducted. Participants included 37 mobility-limited adults (24 women, 13 men), aged 65 to 93 years. Measures included upper (elbow extension) and lower limb (double leg press) one repetition maximum (1RM), and muscle power at both 40% and 70% one repetition maximum. Physical performance measures included stair climb time, the Short Physical Performance Battery, and 4-meter walk time. Factors commonly mediating the relationship between impairments and physical performance were analyzed as covariates. RESULTS Participants had a mean age of 76 years, had five chronic medical conditions, and manifested moderate mobility limitations. Although the associations between the upper and lower limbs were strong (p <.001), the magnitude of association was greater for power (r =.88-.89) as compared to strength (r =.69). Multivariate regression analyses revealed consistently strong relationships between limb muscle power and mobility performance measures. Substituting upper for lower limb power within these models did not materially weaken the relationships. CONCLUSION Muscle power appears to be a more generalized attribute between the upper and lower limbs than is muscle strength, suggesting that mechanisms underlying velocity of movement, as opposed to force production, may be important factors underlying muscle power in elderly persons. Additionally, upper limb muscle power measures may serve as a useful surrogate measure of limb power having implications for clinicians and researchers.
