Abstract
Background Critical illness is a stressful time for patients and their support networks. Although patient-directed educational material to improve the understanding of critical illness exists, both patients and staff members are often unaware of these resources or how to find them. Objectives We aimed to evaluate the impact of the implementation of the American Thoracic Society's (ATS) "Managing the Intensive Care Unity (ICU) Experience: A Proactive Guide for Patients and Families", an ICU orientation pamphlet, on nurses' perceptions of the availability and effectiveness of patient and family educational resources. Methods In a safety-net urban institution, we surveyed medical ICU (MICU) nurses in February 2021 regarding their perceptions of the availability of patient and family educational materials and the time and quality of communication with families of critically ill patients. We then introduced the MICU nurses to the ATS ICU orientation pamphlet to complement patient and family education. Quick response (QR) codes were created, linking to the online versions of the ICU pamphlet, and made available in waiting rooms. Printed copies of the pamphlet were provided to families in the ICU introductory packet upon patient MICU admission. We informed nurses regarding the pamphlet content, website, and QR codes. A postintervention survey was administered 11 months after the initial survey. Changes between pre and postintervention responses were analyzed for significant differences. Debriefing sessions with the MICU nurses were conducted, and subsequent discussions identified opportunities to improve the available educational resources. Results At baseline, 28 of 67 (42%) MICU nurses responded to the survey. Although all nurses provided verbal education to patients and families, only 18% reported knowing about and using additional resources to supplement this education. The postintervention survey was completed by 39% of nurses; 39% of them reported using additional materials to supplement patient and family education. Reported awareness of the ATS ICU pamphlet increased from 4% before implementation to 23% after implementation (P = 0.04). MICU nurses offered suggestions to improve the pamphlet, which thematically fell into three categories: 1) opportunities to alter the ICU pamphlet, 2) opportunities to provide the pamphlet in varied formats, and 3) opportunities to add additional education topics. Conclusions Informing nurses about the ICU pamphlet improved the acceptance and use of the materials, but it was still not accepted by many nurses. Barriers to ICU nurses using patient education resources should be explored to facilitate quality materials reaching patients and complementing patient communication. QR codes may have offered a way to disseminate educational materials to patients and families in a manner not previously considered. The process of evaluating the ICU pamphlet for our institution led to a broader discussion of additional needs for patient and family educational materials for our patient population. We encourage institutions to evaluate the sufficiency of their patient and family educational materials for similar local benefits.

Abstract
High-risk pulmonary embolism (PE) patients can be managed with systemic lysis, catheter-based therapies, or surgical embolectomy. Despite the advent of newer therapies, patients with high-risk PE remain with a 50-60% short-term mortality risk. In such patients, extracorporeal membrane oxygenation (ECMO) is increasingly utilized for hemodynamic support. To evaluate the outcomes of the use of ECMO in patients with high-risk PE. Using the National Inpatient Sample (NIS) database, we identified patients with high-risk PE using ICD 10 codes and compared in-hospital outcomes of patients with and without ECMO support. We identified 38,035 patients with high-risk PE, of whom 820 had undergone ECMO placement. Most patients who underwent ECMO were male (54%), white (65%), and with a mean age of 53.7 years. ECMO use was not associated with a meaningful difference in patient mortality when comparing treatment groups (OR, 1.32 ± 0.39; 0.74-2.35; p = 0.35). Rather, ECMO use was associated with a higher frequency of inpatient complications. ECMO use was not associated with a significant difference in patient mortality in patients with high-risk PE.

Abstract
The American Academy of Sleep Medicine (AASM) recommends that hypopneas be identified using a definition that is based on a ≥30% decrease in airflow associated with a ≥3% reduction in the oxygen saturation or an arousal (H3A) for diagnosis of obstructive sleep apnea (OSA) in adults. This conflicts with the Centers for Medicare and Medicaid Services (CMS) definition, which requires a ≥4% decrease in the oxygen saturation to identify a hypopnea (H4) and does not acknowledge arousals. In 2018, the AASM board of directors constituted a Hypopnea Scoring Rule Task Force (HSRTF) with a mandate to "create a strategy for adoption and implementation of the AASM recommended adult hypopnea scoring criteria among members, payers and device manufacturers." The task force initiated several activities including a survey of AASM accredited laboratories and discussions with polysomnography software vendors. Survey results indicated that most laboratories scored polysomnograms using only the CMS definition. Vendors indicated that they could easily support dual scoring. Informal testing among task force members' laboratories confirmed there would be little additional work if dual scoring was performed. The task force convened several meetings of a working group of OSA content experts and interested parties, with the purpose of creating research recommendations to study the impact on relevant clinical outcomes using the different definitions of hypopnea. Several possible prospective and retrospective approaches were discussed with emphasis on the group of patients diagnosed with OSA based on an apnea-hypopnea index (AHI) using H3A but NOT H4. Based on the deliberations of the working group, the HSRTF submitted recommendations to the AASM Foundation concerning research project strategies for potential grant funding. Further discussions within the HSRTF focused on developing advocacy initiatives among patient stakeholder groups to change payer policy.

Abstract
AbstractA 57-year-old male patient who is a known case of hypertension well controlled on ramipril presented with a history of shortness of breath and palpitation of 3 months duration. The symptoms were insidious in onset; however, it progressed rapidly over the period of 3 months, wherein at present the patient feels breathless in performing normal daily activities of living making him New York Heart Association class III patient. Palpitations are regular in nature and present throughout the time and are exacerbated on performing even light activities within his house. There was associated swelling of bilateral lower limbs that usually improved after a night's rest; however, it was not completely resolved. The individual did not give any history of chest pain, presyncope, syncope, or any other symptoms that pointed toward a cardiac condition.

Abstract
BACKGROUND Thrombosis and inflammation may contribute to the risk of death and complications among patients with coronavirus disease 2019 (Covid-19). We hypothesized that therapeutic-dose anticoagulation may improve outcomes in noncritically ill patients who are hospitalized with Covid-19. METHODS In this open-label, adaptive, multiplatform, controlled trial, we randomly assigned patients who were hospitalized with Covid-19 and who were not critically ill (which was defined as an absence of critical care-level organ support at enrollment) to receive pragmatically defined regimens of either therapeutic-dose anticoagulation with heparin or usual-care pharmacologic thromboprophylaxis. The primary outcome was organ support-free days, evaluated on an ordinal scale that combined in-hospital death (assigned a value of -1) and the number of days free of cardiovascular or respiratory organ support up to day 21 among patients who survived to hospital discharge. This outcome was evaluated with the use of a Bayesian statistical model for all patients and according to the baseline d-dimer level. RESULTS The trial was stopped when prespecified criteria for the superiority of therapeutic-dose anticoagulation were met. Among 2219 patients in the final analysis, the probability that therapeutic-dose anticoagulation increased organ support-free days as compared with usual-care thromboprophylaxis was 98.6% (adjusted odds ratio, 1.27; 95% credible interval, 1.03 to 1.58). The adjusted absolute between-group difference in survival until hospital discharge without organ support favoring therapeutic-dose anticoagulation was 4.0 percentage points (95% credible interval, 0.5 to 7.2). The final probability of the superiority of therapeutic-dose anticoagulation over usual-care thromboprophylaxis was 97.3% in the high d-dimer cohort, 92.9% in the low d-dimer cohort, and 97.3% in the unknown d-dimer cohort. Major bleeding occurred in 1.9% of the patients receiving therapeutic-dose anticoagulation and in 0.9% of those receiving thromboprophylaxis. CONCLUSIONS In noncritically ill patients with Covid-19, an initial strategy of therapeutic-dose anticoagulation with heparin increased the probability of survival to hospital discharge with reduced use of cardiovascular or respiratory organ support as compared with usual-care thromboprophylaxis.

Abstract
Background:The efficacy of ixekizumab (IXE) in biologic-naïve patients with radiographic axial spondyloarthritis (r-axSpA) has been previously presented using traditional axSpA outcome measures, such as BASDAI and ASAS.Objectives:In patients with active r-axSpA, to assess the analgesic efficacy of IXE as it relates to patient-reported and objective measures of inflammation.Methods:The Phase III COAST-V (NCT02696785) multi-center, randomized, double-blind, placebo (PBO)-controlled and active reference arm with adalimumab (ADA) trial investigated the efficacy of IXE in 341 patients (pts) with active r-axSpA for 52 weeks (W). Pts were initially randomized to IXEQ4W, IXEQ2W, PBO, and ADAQ2W. At W16, pts assigned to PBO and ADA were re-randomized to IXEQ2W or Q4W. Changes in spinal pain at night (SP-N) and spinal pain were measured at each study visit and analysed while controlling for CRP levels or mean of BASDAI questions 5 & 6 (Q5: Duration and Q6: Intensity of morning stiffness). Observed data analyses are presented for each group stratified by treatment arm and compared to PBO. In the initial analysis, pts were categorized into 2 sub-groups defined as “Sustained” and “Fluctuating” depending on: CRP <5 mg/L W4-16 vs. CRP ≥5 mg/L at any point beyond W4 between weeks 4-16 respectively. In a second analysis, pts were categorized based on BASDAI Q5/6 improvement: “Sustained” if ≥2-pt improvement W12-16 vs. “Fluctuating” if <2-pt improvement at any point beyond W12 between W12-16.Results:Between W0 and W16, pts treated (tx) with IXEQ4W experienced greater reduction in SP-N than pts tx with ADA, in both CRP sustained and fluctuating groups (Fig 1a). Pts in the IXEQ4W and ADA arms showed different trajectories of pain improvement in the CRP fluctuating groups. For the pts with a fluctuating CRP ≥5 mg/L, pts in IXEQ4W arm demonstrated a greater reduction in SP-N compared to pts in PBO arm (p < .001) at W16, whereas pts in ADA arm did not experience a reduction in SP-N compared to PBO (p = .416). For the pts with a sustained CRP <5mg/L, IXEQ4W and ADA treatments both significantly demonstrated reduction in SP-N compared to PBO at W16 (IXEQ4W: p = .002; ADA: p = .02), with IXEQ4W treatment showing a greater level of reduction (Fig 1a). The pts randomized to ADA and re-randomized to IXEQ2W or Q4W (ADA/IXE) experienced further improvement in SP-N. This effect was sustained over the 52-wk period (Fig 1b). The same pattern of improvement in SP-N was observed when controlling for the BASDAI Q5/6; the SP-N improvement was greater in pts with a sustained BASDAI Q5/6 compared to pts with a fluctuating BASDAI Q5/6, regardless of treatment (Table 1). In the fluctuating BASDAI Q5/6, for pts in ADA/IXE arm, further reduction of both spinal pain and SP-N were observed (Table 1).Table 1.Change in Pain Outcome at baseline, week 16 and week 52 by Inflammation Status as assessed by BASDAI or CRP levels for patients receiving placebo (PBO), adalimumab (ADA), and ixekizumab every 4 weeks (IXE Q4W)Change from baselinePBOADAIXEQ4WbaselineWeek 16(as observed)Week 52PBO/IXE(as observed)baselineWeek 16(as observed)Week 52ADA/IXE(as observed)baselineWeek 16(as observed)Week 52(as observed)Spinal painBASDAI Q5/6 sustained7.54-3.33-4.657.21-4.07-4.57.4-4.52-4.94BASDAI Q5/6 fluctuating7.37-1.32-2.826.76-1.2-2.246.97-1.3-2.52CRP sustained7-1.53-1.936.83-2.9-3.67.23-3.57-4.21CRP fluctuating7.51-1.96-3.637.28-2-2.897.24-2.91-3.93Spinal pain at nightBASDAI Q5/6 sustained7.12-3.21-4.617.26-4.63-4.927.12-4.73-4.91BASDAI Q5/6 fluctuating7.05-1.15-2.886.6-1.2-2.497.03-2.17-2.92CRP sustained7.2-1.87-2.276.76-3.2-3.856.89-3.8-4.12CRP fluctuating7.04-1.69-3.67.24-2.21-3.397.35-3.68-4.38Conclusion:IXE reduced SP-N and spinal pain irrespective of CRP or morning stiffness. Additionally, pts treated with ADA re-randomized to IXE experienced a further reduction in SP-N and spinal pain. Collectively, these results support the additive benefits of IXE in reducing pain above measurable effects on inflammation.Acknowledgements:The authors would like to thank Eglantine Julle-Daniere for writing and editorial contributionsDisclosure of Interests:Kurt de Vlam Speakers bureau: Eli Lilly, Novartis, Pfizer, Paid instructor for: Celgene, Amgen, Consultant of: Elil Lillyn Novartis, UCB, Galapagos, Sandoz, Pfizer, Grant/research support from: Celgene, Gaia Gallo Shareholder of: Eli Lilly, Employee of: Eli Lilly, Philip J Mease Speakers bureau: AbbVie, Amgen, Eli Lilly, Janssen, Novartis, Pfizer, UCB, Consultant of: AbbVie, Amgen, Boehringer Ingelheim, Bristol Myers Squibb, Eli Lilly, Galapagos, Gilead, GlaxoSmithKline, Janssen, Novartis, Pfizer, Sun, UCB, Grant/research support from: AbbVie, Amgen, Bristol Myers Squibb, Eli Lilly, Galapagos, Janssen, Novartis, Pfizer, Sun, UCB, Proton Rahman Speakers bureau: AbbVie, Amgen, BMS, Celgene, Eli Lilly, Janssen, Merck, Novartis, Pfizer, UCB, Consultant of: AbbVie, Amgen, BMS, Celgene, Eli Lilly, Janssen, Merck, Novartis, Pfizer, UCB, Grant/research support from: Janssen, Novartis, Venkatesh Krishnan Shareholder of: Eli Lilly, Employee of: Eli Lilly, David Sandoval Shareholder of: Eli Lilly, Employee of: Eli Lilly, Chen-Yen Lin Shareholder of: Eli Lilly, Employee of: Eli Lilly, Rebecca Bolce Shareholder of: Eli Lilly, Employee of: Eli Lilly, Philip G Conaghan Consultant of: personal fees from: AbbVie, AstraZeneca, BMS, Eli Lilly, EMD Serono, Flexion Therapeutics, Galapagos, Gilead, Novartis, Pfizer

Abstract
OBJECTIVE To evaluate the sensitivity and the stability of the monoclonal antibodies (Aa3c10, b10c1), against truncated Histidine-rich protein 2 (PfHRP2), developed using smart polymer, poly N-isopropylacrylamide, as adjuvant for malarial diagnostic applications in comparison with the available commercial antibodies. METHODS Two hybridoma clones (Aa3c10, b10c1) were used for the production of ascites in BALB/c mice. Purification of monoclonal antibodies from the ascites was carried out using affinity columns. The thermal stability study of monoclonal antibodies was done by storing it at 37°C and 45°C for thirty days. The stored antibodies were analyzed using SDS-PAGE and flow-through device where the antigenantibody interaction was visualized by Protein A colloidal gold solution. Sensitivity was determined by endpoint dilution ELISA and the dissociation constant by competitive ELISA. Sensitive pair optimization was done by sandwich ELISA using biotinylated antibodies. Prototype preparation for lateral flow assay had a colloidal gold-based detection system. RESULTS Thermal stability experiments showed that both mAbs (Aa3c10; b10c1) are stable up to thirty days at 45°C while the commercially available mAbs were stable up to fifteen days only. Compared to commercial antibodies, the mAb Aa3c10, showed the highest sensitivity in end-point titre. In sensitive pair optimization, it was observed that the mAb, b10c1, as a detector and the mAb, Aa3c10, as a capture antibody showed the highest absorbance to detect 50pg/ml PfHRP2 antigen. The prototype formulation of lateral flow assay using the mAbs (Aa3c10; b10c1) showed good reactivity with WHO panel and no false-positive results were observed with twenty clinically negative samples and five P. vivax positive samples. CONCLUSIONS The novel monoclonal antibodies (Aa3c10, b10c1) against truncated PfHRP2, could be a strong potential candidates that can be included in making RDTs with better sensitivity and stability.

Abstract
OBJECTIVE Necrotizing supraglottitis is a rare but potentially morbid infection most often seen in immunocompromised patients. All reported cases have utilized intravenous antibiotic therapy as the mainstay of treatment and many have had associated morbidities. METHODS We describe a case of a 50-year-old previously healthy female who presented with necrotizing epiglottis and was treated with immediate surgical debridement followed by directed antibiotic therapy. RESULTS Our patient rapidly recovered with no further invasive interventions. On follow up she had no further complications or functional deficits. CONCLUSIONS Although uncommon, providers should be aware of the potential benefits of early debridement when treating patients with similar pathology. Early surgical intervention should be considered to avoid local tissue loss, airway interventions, and long-term sequelae.

Abstract
Knee pain is one of the main health issues faced by different people in different parts of the world. Over one fourth of the people above the age of fifty suffer from knee pain. Though there are several physiotherapy treatments for treating knee pain they are not self-applicable and those which are self-applicable by the patient are not highly efficient. This paper deals with an approach towards the use of combining two effective physiotherapy treatments which include vibrations at acupressure points on knee and alternate heating and cooling treatments. These treatments are controlled by a smart phone in which the user can choose their setting depending on intensity and places of pain. The knee pad controlled using the smart phone serves as a self-applicable and effective knee pain treatment especially for the elderly. Heating and cooling combination therapy will be a suitable alternative for treatment of musculoskeletal diseases, decreases muscle spasms, muscular pain/tension and also increases the speed of nerve conduction, thus improving range of motion. This methodology also helps to relieve the sinusitis pain, chronic low back pain and muscular sprain in athletes.

Abstract
We have identified a non-steroidal selective androgen receptor modulator (SARM), termed LY305, that is bioavailable through a transdermal route of administration while highly cleared via hepatic metabolism to limit parent compound exposure in the liver. Selection of this compound and its transdermal formulation was based on the optimization of skin absorption properties using both in vitro and in vivo skin models that supported PBPK modeling for human PK predictions. This molecule is an agonist in perineal muscle while being a weak partial agonist in the androgenic tissues such as prostate. When LY305 was tested in animal models of skeletal atrophy it restored the skeletal muscle mass through accelerated repair. In a bone fracture model, LY305 remained osteoprotective in the regenerating tissue and void of deleterious effects. Finally, in a small cohort of healthy volunteers, we assessed the safety and tolerability of LY305 when administered transdermally. LY305 showed a dose-dependent increase in serum exposure and was well tolerated with minimal adverse effects. Notably, there were no statistically significant changes to hematocrit or HDL after 4-week treatment period. Collectively, LY305 represents a first of its kind de novo development of a non-steroidal transdermal SARM with unique properties which could find clinical utility in hypogonadal men.

Abstract
Self-expandable metal stents are often used to treat obstructive large bowel cancers. This study assessed the safety and efficacy of colonic stent insertion carried out in a district general hospital. Methods A retrospective review was carried out between 1 January 2007 and 28 February 2014 to identify patients who underwent stent insertion for malignant colorectal obstruction. Results Seventy-five patients (median age 75.2 years, 70.6% male) with primary colorectal cancer underwent stent insertion - 53 underwent semi-elective self-expanded metal stent insertion (for subacute bowel obstruction) and 22 had emergency stent inserted (for acute bowel obstruction). The majority (88%) had self-expanded metal stents inserted for palliation. Technical and clinical success rates were 98.7% and 91.2%, respectively. One patient had stent-related perforation; there was no procedure-related mortality. Conclusion This study shows that self-expanded metal stent insertion in malignant colorectal obstruction is safe and effective and can be successfully delivered in a district general hospital with high technical and clinical success rates.

Sustained p16 INK4a expression is required to prevent IR-induced tumorigenesis in mice. Oncogene 2016; 36:1309-1314.

Abstract
Exposure of murine and human tissues to ionizing radiation (IR) induces the expression of p16INK4a, a tumor suppressor gene and senescence/aging biomarker. Increased p16INK4a expression is often delayed several weeks post exposure to IR. In this context, it remains unclear if it occurs to suppress aberrant cellular growth of potentially transformed cells or is simply a result of IR-induced loss of tissue homeostasis. To address this question, we used a conditional p16INK4a null mouse model and determined the impact of p16INK4a inactivation long-term post exposure to IR. We found that, in vitro, bone marrow stromal cells exposed to IR enter DNA replication following p16INK4a inactivation. However, these cells did not resume growth; instead, they mostly underwent cell cycle arrest in G2. Similarly, delayed inactivation of p16INK4a in mice several weeks post exposure to IR resulted in increased BrdU incorporation and cancer incidence. In fact, we found that the onset of tumorigenesis was similar whether p16INK4a was inactivated before or after exposure to IR. Overall, our results suggest that IR-induced p16INK4a dependent growth arrest is reversible in mice and that sustained p16INK4a expression is necessary to protect against tumorigenesis.

Abstract
INTRODUCTION Self blood glucose monitoring is an important context of self care in the management of diabetes mellitus. All the guidelines must be followed while performing self blood glucose monitoring and tracking of values is essential to facilitate the physician while titrating the drugs and /or doses of anti diabetes medication. Self titration by patients following self monitoring must be discouraged. AIM To assess the knowledge and practice of self blood glucose monitoring among diabetes patients and extent of self titration of anti diabetes medicines among diabetes patients based on self blood glucose monitoring. MATERIALS AND METHODS This pilot, cross-sectional, observational study was conducted using a validated questionnaire among adult male and female diabetes patients performing self blood glucose monitoring at home. Diabetes patients with complications and juvenile diabetes patients were excluded. RESULTS Out of 153 patients surveyed, only 37 (24.1%) (20 males, 17 females) patients were aware and have been following self blood glucose monitoring appropriately. About 116 (75.8%) (64 males, 52 females) of patients were devoid of adequate knowledge and did not practice self blood glucose monitoring in a proper way. Ninety eight (64.05%) accepted that they self titrate their anti diabetic medicines based on self monitoring. CONCLUSION Self monitoring of blood glucose should be encouraged and patients should be taught importance of following correct steps and tracking of self monitoring by physician or diabetes educator.

Abstract
BACKGROUND Host response to periodontal disease includes the release of different enzymes from stromal, epithelial or inflammatory cells. The enzymes which are produced from these cells are associated with cell injury and cell death like: Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Alkaline phosphatase (ALP) and Blood urea nitrogen (BUN). Normal enzymatic activity of these enzymes is necessary for healthy functioning of gingiva and periodontium. The aim of the study is to estimate the levels of enzymes AST, ALT, ALP and BUN and to correlate the level of estimated enzymes with that of clinical parameters in the saliva of Healthy subjects, Gingivitis patients and patients with chronic periodontitis. METHODS The study included a total of 40 male subjects within the age group of 21 to 50 years, and examined the activity of enzymes AST, ALT, ALP and BUN in saliva spectrophotometrically and compared their values between healthy subjects, gingivitis and chronic periodontitis patients. Clinical parameters like OHI - S (Oral hygiene index - Simplified, SBI (Sulcus Bleeding Index), PPD (Probing Pocket Depth), CAL (Clinical Attachment Level), and PI (Periodontal Index) were recorded. RESULTS Obtained results showed statistically significant increases of activity of AST, ALT, ALP, and BUN in saliva from patients with periodontal disease (p<0.001) in relation to gingivitis and control groups. There was also an increase in periodontal parameters with an increase in salivary enzymes. CONCLUSION The present study shows that the salivary enzyme activity can be used as biomarkers to determine periodontal tissue damage, which may be useful in diagnosis, prognosis and evaluation of post therapy effects in periodontal disease.

Abstract
A physiologically based pharmacokinetic (PBPK) model was developed that describes the concentration and biodistribution of fluorescently labeled nanoparticles in mice used for the controlled delivery of dexamethasone in acute lymphoblastic leukemia (ALL) therapy. The simulated data showed initial spikes in nanoparticle concentration in the liver, spleen, and kidneys, whereas concentration in plasma decreased rapidly. These simulation results were consistent with previously published in vivo data. At shorter time scales, the simulated data predicted decrease of nanoparticles from plasma with concomitant increase in the liver, spleen, and kidneys before decaying at longer timepoints. Interestingly, the simulated data predicted an unaccounted accumulation of about 50% of the injected dose of nanoparticles. Incorporation of an additional compartment into the model justified the presence of unaccounted nanoparticles in this compartment. Our results suggest that the proposed PBPK model can be an excellent tool for prediction of optimal dose of nanoparticle-encapsulated drugs for cancer treatment.

Abstract
Smoking and OSA are widely prevalent and are associated with significant morbidity and mortality. It has been hypothesized that each of these conditions adversely affects the other, leading to increased comorbidity while altering the efficacy of existing therapies. However, while the association between smoking and OSA is plausible, the evidence is less than conclusive. Cigarette smoking may increase the severity of OSA through alterations in sleep architecture, upper airway neuromuscular function, arousal mechanisms, and upper airway inflammation. Conversely, some evidence links untreated OSA with smoking addiction. Smoking cessation should improve OSA, but the evidence to support this is also limited. This article reviews the current evidence linking both conditions and the efficacy of various treatments. Limitations of the current evidence and areas in need of future investigation are also addressed.

Abstract
Spinal cord injury (SCI) leads to formation of a fibrotic scar that is inhibitory to axon regeneration. Recent evidence indicates that the fibrotic scar is formed by perivascular fibroblasts, but the mechanism by which they are recruited to the injury site is unknown. Using bone marrow transplantation in mouse model of spinal cord injury, we show that fibroblasts in the fibrotic scar are associated with hematogenous macrophages rather than microglia, which are limited to the surrounding astroglial scar. Depletion of hematogenous macrophages results in reduced fibroblast density and basal lamina formation that is associated with increased axonal growth in the fibrotic scar. Cytokine gene expression analysis after macrophage depletion indicates that decreased Tnfsf8, Tnfsf13 (tumor necrosis factor superfamily members) and increased BMP1-7 (bone morphogenetic proteins) expression may serve as anti-fibrotic mechanisms. Our study demonstrates that hematogenous macrophages are necessary for fibrotic scar formation and macrophage depletion results in changes in multiple cytokines that make the injury site less fibrotic and more conducive to axonal growth.

Abstract
The pressure dependence of the 35Cl-NQR frequencies in barium chlorate monohydrate and strontium chlorate, has been investigated up to 7000 kg cm-2. Ba(ClO3)2 · H2O shows a single 35Cl-NQR line at 29.337 MHz (T = 297 K, p = 1 bar). ν(35Cl) increases linearly with pressure in the range studied, with (1/ν )(∂ν/∂p)T = + 0.409 x 10-6 kg-1 cm2 which is much smaller than observed in NaClO3 and KCIO3. Sr(ClO3)2 also gave a single 35Cl-NQR frequency at 20.105 MHz (T = 297 K, p = 1 bar). The pressure dependence is very small and negative in this case. The data in both cases have been analysed to obtain the volume dependence of the torsional frequency. It is pointed out that explicit pressure effects on the electric field gradient have to be taken into account to provide an explanation for the observed pressure dependence of ν (35Cl).
