In our previous data we observed the presence of products of degraded blood (the iron/hemosiderin) in the meningeal lymphatics (ML) and in the deep cervical lymph node (dcLN) in patients who died after hemorrhagic events (brain trauma and stroke). Here we demonstrate novel data related to the brain clearance from the blood after hemorrhagic stroke (HeStr) via the ML in rats. For the first time, we show non-invasive laser method for stimulation of ML drainage for the brain recovery after HeStr using laser irradiation though the intact skull and skin.
Experiments were carried out in adult mongrel rats (250-280 g) using model of HeStr. All procedures were performed in accordance with the “Position of the American Heart Association on Research Animal Use“ (Circulation 1985; 71:849A). The new generation laser 1268 nm (30 nm, 7 min) was used for stimulation of the ML drainage through the intact skull and skin that was analyzed in vivo (two-photon, fluorescent, optical coherent tomography imaging) and ex vivo (immunohistochemical, confocal data) using markers of lymphatic endothelium (LYVE-1/LYVE-1 conjugated with Alexa 488 and Prox-1).
The results clearly demonstrated that 1h after HeStr the iron/hemosiderin (detected by atomic absorption spectroscopy and histological method) accumulated in the dcLN and observed in the ML. The laser application caused stimulation of the ML drainage (analyzed by dextran movement in vivo) and was accompanied by decrease in the iron/hemosiderin level in the brain tissues with an appropriate increase of their level in the dcLN. The application of laser (one time a day) during one week contributed a better recovery after HeStr vs. the control group (without laser) that was confirmed by analysis of inflammatory factors (C-reactive protein, IL-6 and lipoprotein-associated phospholipase A2, immunoassay analysis), macrophages infiltration (confocal imaging), edema, necrotic and ischemic events (histological data).
In sum, our results suggest that laser 1268 nm by stimulation of endogenous processes of brain lymphatic drainage might be a novel auxiliary non-invasive method for brain recovery after HeStr.

Published: January 2019

Background: People with haematological malignancies have different end-of-life care patterns from those with other cancers and are more likely to die in hospital. Little is known about patient and relative preferences at this time and whether these are achieved. Aim: To explore the experiences and reflections of bereaved relatives of patients with leukaemia, lymphoma or myeloma, and examine (1) preferred place of care and death; (2) perceptions of factors influencing attainment of preferences; and (3) changes that could promote achievement of preferences. Design: Qualitative interview study incorporating ‘Framework’ analysis. Setting/participants: A total of 10 in-depth interviews with bereaved relatives. Results: Although most people expressed a preference for home death, not all attained this. The influencing factors include disease characteristics (potential for sudden deterioration and death), the occurrence and timing of discussions (treatment cessation, prognosis, place of care/death), family networks (willingness/ability of relatives to provide care, knowledge about services, confidence to advocate) and resource availability (clinical care, hospice beds/policies). Preferences were described as changing over time and some family members retrospectively came to consider hospital as the ‘right’ place for the patient to have died. Others shared strong preferences with patients for home death and acted to ensure this was achieved. No patients died in a hospice, and relatives identified barriers to death in this setting. Conclusion: Preferences were not always achieved due to a series of complex, interrelated factors, some amenable to change and others less so. Death in hospital may be preferred and appropriate, or considered the best option in hindsight.

Background Minocycline has neurological anti-inflammatory properties and has been hypothesised to have antipsychotic effects. Aim The aim of this study was to investigate, using routinely collected United Kingdom primary health care data, whether adolescent men and women are more or less likely to receive an urgent psychiatric referral during treatment for acne with minocycline compared with periods of non-treatment. Method A self-controlled case series using United Kingdom Clinical Practice Research Datalink to calculate the incidence rate ratio of urgent psychiatric referrals for individuals, comparing periods during which minocycline was prescribed with unexposed periods, adjusted for age. Results We found 167 individuals who were at the time exposed to minocycline for a mean of 99 days and who received an urgent psychiatric referral. There was no difference in psychiatric referral risk during periods of exposure compared with periods of non-exposure: incidence rate ratio first 6 weeks of exposure 1.96, 95% confidence interval 0.82–4.71, p=0.132; incidence rate ratio remaining exposure period=1.97, 95% confidence interval 0.86–4.47, p=0.107. Conclusions We found no evidence in support of a protective effect of minocycline against severe psychiatric symptoms in adolescence.
Perinatal exposure to fluoxetine increases anxiety- and depressive-like behaviours and alters glutamatergic markers in the prefrontal cortex and hippocampus of male adolescent rats: A comparison between Sprague-Dawley rats and the Wistar-Kyoto rat model of depression

Published: January 2019

Background: With approximately 10% of pregnant women prescribed antidepressant drugs for the treatment of depressive disorders, there is growing concern regarding the potential long-term effects of this exposure on offspring. Research is needed in clinically relevant models to determine the effects on offspring behaviour and associated neurobiological systems. Aim: The aim of this study was to determine the effects of maternal fluoxetine treatment on anxiety-like and depressive-like behaviours in adolescent offspring as well as associated glutamatergic markers, using a clinically relevant rodent model of depression. Methods: Wistar-Kyoto (model of innate depression) and Sprague-Dawley rats were treated with fluoxetine (10 mg/kg) from gestational day 0 to postnatal day 14. Male offspring underwent behavioural testing (open field, elevated plus maze, forced swim test) at adolescence followed by quantitative immuno-detection of glutamatergic markers in the prefrontal cortex and ventral hippocampus. Results: Perinatal fluoxetine exposure exacerbated the anxiety-like and depressive-like phenotype in Wistar-Kyoto offspring and induced an anxiety-like and depressive-like phenotype in Sprague-Dawley offspring. Wistar-Kyoto offspring showed reductions in NMDA receptor NR1, NR2A and NR2B subunits, as well as post-synaptic density 95 (PSD-95) and metabotropic glutamate receptor subtype 1 (mGluR1) in the prefrontal cortex; perinatal fluoxetine exposure further reduced NR1, NR2A, PSD-95 and mGluR1 expression in Wistar-Kyoto as well as Sprague-Dawley offspring. In the ventral hippocampus perinatal fluoxetine exposure reduced PSD-95 and increased metabotropic glutamate receptor subtype 5 (mGluR5) and Homer1b/c in both Sprague-Dawley and Wistar-Kyoto strains. Conclusion: These findings suggest that maternal fluoxetine treatment exacerbates effects of underlying maternal depression on offspring behaviour, which may be mediated through alterations in the glutamatergic system. Further research investigating how to minimise these effects, whilst ensuring optimal treatment for mothers, is essential to move the field forward.

Published: January 2019

Background: The purpose of this study was to examine how frequently invasive intensive care unit (ICU) treatments are delivered to critically ill patients despite clinicians’ impressions that ICU care may be nonbeneficial. Methods: Patients admitted to the medical ICU of an academic public hospital were prospectively categorized according to guidelines from the Society of Critical Care Medicine which classifies patients based on severity of illness and likelihood of recovery (categories 1-4). Clinical data and use of ICU treatments in patients with high (category 1) and low (category 3) likelihoods of benefit were collected by chart review. Multivariable regression analyses examined associations between use of invasive treatments and patient categories, and clinical factors associated with receiving invasive ICU treatments despite low likelihood of benefit. Results: There were 533 patients (369 in category 1 and 164 in category 3) in the study. A total of 19.8%, 29.9%, and 28.9% of patient-days on mechanical ventilation, vasopressors, and renal replacement therapy, respectively, were delivered to patients who were considered unlikely to benefit from ICU treatments (category 3) and ultimately did not survive hospitalization. These patients also received 35.2% of cardiopulmonary resuscitation attempts and 22.6% of central venous catheter placements. Clinicians’ impressions of likelihood of benefit (category 1 vs 3) were not associated with odds of receiving invasive ICU treatments. Clinical characteristics associated with greater odds of receiving potentially nonbeneficial treatments included older age, presence of dementia or malignancy, and higher Acute Physiologic Assessment and Chronic Health Evaluation score. Conclusions: Invasive ICU treatments are frequently delivered to patients who are not expected to benefit from ICU care and die during hospitalization. These findings highlight the need to improve utilization of ICU services among patients with advanced medical illnesses.

Published: January 2019

Objective: To compare the influence of 3 different time protocols of cleft lip and palate operations on the growth of the dentoalveolar arch in patients with unilateral cleft lip and palate (UCLP). Materials and Methods: We evaluated 64 plaster casts of 8-year-old boys with UCLP operated on according to 3 different time protocols: lip repair at the age of 6 months and palate repair at 4 years, lip repair at 3 months and palate repair at 9 months, and neonatal lip repair and palate repair at 9 months. The control group contained 13 plaster casts of 8-year-old boys. The dentoalveolar arch width was measured between deciduous canines and between the second deciduous molars; the length was measured between incisive papilla and the line connecting both tuber maxillae. Results: All measured distances were statistically significantly smaller in boys with UCLP than in the control group. Intercanine width was not statistically significantly different between the patients operated on according to the different time protocols. In comparison to the lip repair at 6 months and palate repair at 4 years, the intermolar width was statistically significantly smaller in the group with neonatal lip repair; the alveolar arch length was statistically significantly shorter in both groups with lip repair performed neonatally or at 3 months. Conclusions: The length of the dentoalveolar arch is shorter after surgical repair of cleft lip neonatally or at the age of 3 months. Cleft palate repair at 9 months can contribute to a reduction in the width of the dentoalveolar arch.

Published: January 2019

Background: Osteochondral allograft (OCA) transplantation is a useful treatment for posttraumatic ankle arthritis in young patients, but failure rates are high and reoperations are not uncommon. The aim of this study was to evaluate the outcomes of failed ankle OCA transplantation converted to ankle arthrodesis (AA) or total ankle arthroplasty (TAA). Methods: We evaluated 24 patients who underwent salvage procedures (13 AA and 11 TAA) after primary failed ankle OCA transplantation. Reoperations were assessed. Failure of the salvage procedure was defined as an additional surgery that required a revision AA/TAA or amputation. Evaluation among nonfailing ankles included the American Academy of Orthopaedic Surgeons Foot and Ankle Module (AAOS-FAM), pain, and satisfaction. Results: In the salvage AA cohort, 3 patients were classified as failures (2 revision AA and 1 amputation). The 10 nonfailing patients had a mean follow-up of 7.4 years. Eighty-eight percent were satisfied with the procedure, but 63% reported continued problems with their ankle (eg, pain, swelling, stiffness). Mean pain level was 1.9 and AAOS-FAM core score was 83±13. In the salvage TAA cohort, 2 patients were classified as failures (both revision TAA). The 9 nonfailing patients had a mean follow-up of 3.8 years. Fifty percent were satisfied with the procedure, but 40% reported continued problems with their ankle. The mean pain level was 1.3, and the median AAOS-FAM core score was 82±26. Conclusion: Revision and reoperation rates for salvage procedures following failed OCA transplantation of the ankle are higher compared to published data for primary AA and TAA procedures. However, we believe OCA transplantation can serve as an interim procedure for younger patients with advanced ankle joint disease who may not be ideal candidates for primary AA or TAA at the time of initial presentation. Level of Evidence: Level IV, case series.

Published: January 2019

Background: There is a concern for higher rates of wound complications and a potentially increased periprosthetic joint infection (PJI) risk after total hip arthroplasty (THA) with the direct anterior approach (DAA) compared to the posterolateral approach (PLA). Our purpose was to compare PJI risk after THA with the DAA or the PLA and to identify risk factors for PJI after primary THA. Methods: Clinical characteristics of patients treated in our institution with primary DAA or PLA THA between 1/2010 and 12/2015 were retrospectively reviewed. The respective deep PJI rates were calculated. A logistic regression model was constructed to determine a potential difference in the PJI risk between the 2 groups, and risk factors for hip PJI in all patients. Results: During the period studied, there were 1,182 DAA THAs and 18,853 PLA THAs. The PJI rate was 0.25% for the DAA group and 0.31% for the PLA group ( p = 1.0). The DAA was not associated with a significantly increased risk for PJI compared to the PLA. Compared to younger patients, older patients had lower PJI risk; patient discharge to home was also associated with lower PJI risk compared to other discharge disposition; longer length of stay was associated with higher PJI risk compared to shorter length of stay. Conclusion: The DAA is equally safe compared the PLA with respect to PJI risk. Younger age, discharge to facilities other than home and increased length of stay increase the risk for deep PJI after primary THA.

Introduction: The purpose of the current study was to investigate the periprocedural and long-term outcomes of stent implantation for de novo subclavian artery (SCA) disease. Material and Methods: We retrospectively investigated consecutive patients with de novo SCA lesions undergoing elective endovascular therapy procedures at our center between April 2004 and September 2015. All patients were included in the analyses of periprocedural outcomes, including procedural and clinical success. Subsequently, patients who completed the clinical follow-up and were assessed with brachial systolic pressure differences between the diseased and the contralateral arms, or angiographic stenosis, after stent implantation with procedural success were included in the analyses of long-term outcomes, including primary patency. Results: There were 62 patients (median 71.0 years, interquartile range 65.3-76.0 years; 45 men) with 62 de novo SCA lesions included in the analyses of periprocedural outcomes. There were 46 stenoses (74.2%) and 16 occlusions (25.8%). Our results indicated high procedural success rates for overall (95.2%), stenotic (97.8%), and occlusive (87.5%) lesions. Similarly, high clinical success rates were observed for overall (91.9%), stenotic (93.5%), and occlusive (87.5%) lesions. The median follow-up time was 6.0 years (interquartile range, 2.6-8.3 years). There were 48 patients with 48 de novo SCA lesions included in the analyses of long-term outcomes. Primary patency estimates were 97.7% (1 year), 97.7% (3 years), 93.1% (5 years), and 87.6% (7 years). Also, we observed a high estimate for freedom from reintervention for the target vessel (93.8%). Conclusion: Stent implantation for de novo SCA disease can be performed successfully and safely with favorable periprocedural and long-term outcomes.

Background The early diagnosis of cardiac abnormalities in young athletes may be helpful not only to identify subjects potentially at risk of sudden cardiac death but also to prevent stress-related cardiac dysfunction and cardiovascular events during the life of these subjects. The aim of our study was to investigate the prevalence of cardiac abnormalities in a population of young male soccer players undergoing pre-participation screening through electrocardiogram and trans-thoracic echocardiography. Methods All consecutive male football players undergoing pre-participation screening comprehensive of medical history, physical examination, 12-lead electrocardiogram and trans-thoracic echocardiography at the FMSI Sport Medicine Institute in Rome between January 2008–March 2009 were enrolled in the study. Results Overall, 2261 consecutive young athletes aged 12.4 ± 2.6 years were evaluated. Training-unrelated electrocardiogram abnormalities were observed in 65 (2.9%) athletes. Abnormal trans-thoracic echocardiography was observed in 102 athletes (4.5%), including two cases of hypertrophic cardiomyopathy, eight of mild left ventricular hypertrophy, six of mild left ventricular dilation and 17 of bicuspid aortic valve. An abnormal electrocardiogram was associated with anomalous trans-thoracic echocardiography in 11/65 (16.9%) cases. All athletes requiring sport disqualification were identified by electrocardiogram. Notably, among 2216 athletes with a normal electrocardiogram, 91 had abnormal trans-thoracic echocardiography, including six cases of left ventricular dilation and six of ventricular hypertrophy. Conclusions In a wide population of peri-pubertal male athletes, evaluation of the electrocardiogram identified all cardiac diseases requiring sport disqualification. Trans-thoracic echocardiography alone allowed the identification of cardiac abnormalities potentially leading to cardiomyopathies or major cardiovascular events over time.

Published: January 2019

Background: Food and Drug Administration–approved daptomycin dosing uses actual body weight, despite limited dosing information for obese patients. Studies report alterations in daptomycin pharmacokinetics and creatine phosphokinase elevations associated with higher weight-based doses required for obese patients. Limited information regarding clinical outcomes with alternative daptomycin dosing strategies in obesity exists. Objective: This study evaluates equivalency of clinical and safety outcomes in obese patients with daptomycin dosed on adjusted body weight versus a historical cohort using actual body weight. Methods: This retrospective, single center study compared equivalency of outcomes with two one-sided tests in patients with body mass index ⩾30 kg/m2 who received daptomycin dosed on actual body weight versus adjusted body weight. The primary outcome was clinical failure. Secondary outcomes included 90-day readmission and 90-day mortality. A combined safety endpoint included creatine phosphokinase elevation, patient-reported myopathy, and rhabdomyolysis. Results: A total of 667 patients were screened for inclusion; 101 patients were analyzed with 50 in the actual body weight cohort and 51 in the adjusted body weight cohort. The two regimens were statistically equivalent for clinical failure (2% actual body weight versus 4% adjusted body weight; p < 0.001 for equivalency). The two regimens were also statistically equivalent for 90-day mortality (6% actual body weight versus 4% adjusted body weight; p = 0.0014 for equivalency). Limitations include single center, retrospective design, and sample size. Daptomycin dosing intensified throughout the study period. Conclusion: The two daptomycin dosing cohorts were statistically equivalent for both clinical failure and 90-day mortality. More data are needed to assess outcomes with higher (⩾8 mg/kg/day) daptomycin doses in this patient population.
