Abstract
The limited efficacy of currently approved immunotherapies in EGFR-driven lung adenocarcinoma (LUAD) underscores the need to better understand alternative mechanisms governing local immunosuppression to fuel novel therapies. Elevated surfactant and GM-CSF secretion from the transformed epithelium induces tumor-associated alveolar macrophage (TA-AM) proliferation which supports tumor growth by rewiring inflammatory functions and lipid metabolism. TA-AM properties are driven by increased GM-CSF-PPARγ signaling and inhibition of airway GM-CSF or PPARγ in TA-AMs suppresses cholesterol efflux to tumor cells, which impairs EGFR phosphorylation and restrains LUAD progression. In the absence of TA-AM metabolic support, LUAD cells compensate by increasing cholesterol synthesis, and blocking PPARγ in TA-AMs simultaneous with statin therapy further suppresses tumor progression and increases proinflammatory immune responses. These results reveal new therapeutic combinations for immunotherapy resistant EGFR-mutant LUADs and demonstrate how cancer cells can metabolically co-opt TA-AMs through GM-CSF-PPARγ signaling to provide nutrients that promote oncogenic signaling and growth.

Abstract
We recently described the development of a database of 810 R-loop mapping datasets and used this data to conduct a meta-analysis of R-loops. R-loops are three-stranded nucleic acid structures containing RNA:DNA hybrids and we were able to verify that 30% of expressed genes have an associated R-loop in a location conserved manner.. Moreover, intergenic R-loops map to enhancers, super enhancers and with TAD domain boundaries. This work demonstrated that R-loop mapping via high-throughput sequencing can reveal novel insight into R-loop biology, however the analysis and quality control of these data is a non-trivial task for which few bioinformatic tools exist. Herein we describe RLSuite, an integrative R-loop bioinformatics framework for pre-processing, quality control, and downstream analysis of R-loop mapping data. RLSuite enables users to compare their data to hundreds of public datasets and generate a user-friendly analysis report for sharing with non-bioinformatician colleagues. Taken together, RLSuite is a novel analysis framework that should greatly benefit the emerging R-loop bioinformatics community in a rapidly expanding aspect of epigenetic control that is still poorly understood.

Abstract
BACKGROUND AND OBJECTIVE Cartilage-hair hypoplasia (CHH) syndrome is a rare autosomal recessive syndrome associated with skeletal dysplasia, varying degrees of combined immunodeficiency (CID), short stature, hair hypoplasia, macrocytic anemia, increased risk of malignancies, and Hirschsprung disease. To provide clinical and immunological insights obtained from 2 unrelated patients who displayed clinical characteristics of CHH. METHODS Two patients with suspected CHH syndrome due to skeletal dysplasia and immunodeficiency underwent an immunological and genetic work-up using flow cytometry, next-generation sequencing (NGS) of the immune repertoire, and Sanger sequencing to identify the underlying defects. RESULTS Patient 1 presented with low birth weight and skeletal dysplasia. Newborn screening was suggestive of T-cell immunodeficiency, as T-cell receptor excision circle levels were undetectable. Both the T-cell receptor (TCR) Vß and TCR-g (TRG) repertoires were restricted, with evidence of clonal expansion. Genetic analysis identified compound heterozygous RMRP variants inherited from both parents. Patient 2 presented with recurrent lung and gastrointestinal infections, skeletal dysplasia, failure to thrive, and hepatomegaly. The polyclonal pattern of the TCRß repertoire was normal, with only slight overexpression of TCR-ßV20 and restricted expression of Vßs. TRG expressed a normal diverse repertoire, similar to that of the healthy control sample. Genetic analysis identified biallelic novel regulatory variants in RMRP. Both parents are carriers of this mutation. CONCLUSION Our findings demonstrate how the immunological work-up, supported by genetic findings, can dramatically change treatment and future outcome in patients with the same clinical syndrome.

Abstract
OBJECTIVE We aimed at assessing the association between demographical and clinical data and the intrahospital mortality in older patients with COVID-19 in Belgium. METHODS Descriptive, retrospective study of consecutive patients admitted to Brugmann university hospital, Brussels (Belgium) due to COVID-19 (Mars-September-2020). INCLUSION CRITERIA Patients aged ≥ 70 years admitted to acute care with a positive PCR-RT test, or a highly indicative computed tomography scan. EXCLUSION CRITERIA Patients transferred to another institution during hospitalization. OUTCOME MEASURE All-cause intrahospital mortality. Demographic, clinical data, presence of comordibidties and comprehensive geriatric assessment were collected. Adjusted and unadjusted logistic regression were performed. RESULTS From the 226 eligible patients, 160 (82.7 ± 6.5-year-old; 57.5 % females) met inclusion criteria, from which 67 (42 %) died during hospital stay. The adjusted logistic regression showed an association between intrahospital mortality and increasing age [OR = 1.09 per every year increase (95 % CI 1.02-1.16); p <0.001], type 2 diabetes [OR = 2.75 ( 1.17-6.46); p = 0.021], and acute respiratory distress syndrome (ARDS) [OR = 8.67 ( 3.48-21.61); p < 0.01]. CONCLUSIONS A higher positive association between intrahospital mortality and increasing age, type 2 diabetes, and ARDS was found. The prognosis value of the comprehensive geriatric assessment in older people with COVID-19 in Belgium requires further studies.

Elevated murine HB-EGF confers sensitivity to diphtheria toxin in EGFR-mutant lung adenocarcinoma. Dis Model Mech 2021; 14:272093.

Abstract
Conditional ablation of defined cell populations in vivo can be achieved using genetically engineered mice in which the human diphtheria toxin (DT) receptor (DTR) is placed under control of a murine tissue-specific promotor, such that delivery of DT selectively ablates cells expressing this high-affinity human DTR; cells expressing only the endogenous low-affinity mouse DTR are assumed to be unaffected. Surprisingly, we found that systemic administration of DT induced rapid regression of murine lung adenocarcinomas that express human mutant EGFR in the absence of a transgenic allele containing human DTR. DT enzymatic activity was required for tumor regression, and mutant EGFR-expressing tumor cells were the primary target of DT toxicity. In FVB mice, EGFR-mutant tumors upregulated expression of HBEGF, which is the DTR in mice and humans. HBEGF blockade with the enzymatically inactive DT mutant CRM197 partially abrogated tumor regression induced by DT. These results suggest that elevated expression of murine HBEGF, i.e. the low-affinity DTR, confers sensitivity to DT in EGFR-mutant tumors, demonstrating a biological effect of DT in mice lacking transgenic DTR alleles and highlighting a unique vulnerability of EGFR-mutant lung cancers.

Abstract
BACKGROUND AND PURPOSE Although current radiologic evaluation of degenerative cervical myelopathy by conventional MR imaging accurately demonstrates spondylosis or degenerative disc disease causing spinal cord dysfunction, conventional MR imaging still fails to provide satisfactory anatomic and clinical correlations. In this context, we assessed the potential value of quantitative cervical spinal cord T1 mapping regarding the evaluation of patients with degenerative cervical myelopathy. MATERIALS AND METHODS Twenty patients diagnosed with mild and moderate-to-severe degenerative cervical myelopathy and 10 healthy subjects were enrolled in a multiparametric MR imaging protocol. Cervical spinal cord T1 mapping was performed with the MP2RAGE sequence procedure. Retrieved data were processed and analyzed regarding the global spinal cord and white and anterior gray matter on the basis of the clinical severity and the spinal canal stenosis grading. RESULTS Noncompressed levels in healthy controls demonstrated significantly lower T1 values than noncompressed, mild, moderate, and severe stenotic levels in patients. Concerning the entire spinal cord T1 mapping, patients with moderate-to-severe degenerative cervical myelopathy had higher T1 values compared with healthy controls. Regarding the specific levels, patients with moderate-to-severe degenerative cervical myelopathy demonstrated a T1 value increase at C1, C7, and the level of maximal compression compared with healthy controls. Patients with mild degenerative cervical myelopathy had lower T1 values than those with moderate-to-severe degenerative cervical myelopathy at the level of maximal compression. Analyses of white and anterior gray matter confirmed similar results. Strong negative correlations between individual modified Japanese Orthopaedic Association scores and T1 values were also observed. CONCLUSIONS In this preliminary study, 3D-MP2RAGE T1 mapping demonstrated increased T1 values in the pathology tissue samples, with diffuse medullary alterations in all patients with degenerative cervical myelopathy, especially relevant at C1 (nonstenotic level) and at the maximal compression level. Encouraging correlations observed with the modified Japanese Orthopaedic Association score make this novel approach a potential quantitative biomarker related to clinical severity in degenerative cervical myelopathy. Nevertheless, patients with mild degenerative cervical myelopathy demonstrated nonsignificant results compared with healthy controls and should now be studied in multicenter studies with larger patient populations.

Characterization of the public transit air microbiome and resistome reveals geographical specificity. MICROBIOME 2021; 9:112.

Abstract
BACKGROUND The public transit is a built environment with high occupant density across the globe, and identifying factors shaping public transit air microbiomes will help design strategies to minimize the transmission of pathogens. However, the majority of microbiome works dedicated to the public transit air are limited to amplicon sequencing, and our knowledge regarding the functional potentials and the repertoire of resistance genes (i.e. resistome) is limited. Furthermore, current air microbiome investigations on public transit systems are focused on single cities, and a multi-city assessment of the public transit air microbiome will allow a greater understanding of whether and how broad environmental, building, and anthropogenic factors shape the public transit air microbiome in an international scale. Therefore, in this study, the public transit air microbiomes and resistomes of six cities across three continents (Denver, Hong Kong, London, New York City, Oslo, Stockholm) were characterized. RESULTS City was the sole factor associated with public transit air microbiome differences, with diverse taxa identified as drivers for geography-associated functional potentials, concomitant with geographical differences in species- and strain-level inferred growth profiles. Related bacterial strains differed among cities in genes encoding resistance, transposase, and other functions. Sourcetracking estimated that human skin, soil, and wastewater were major presumptive resistome sources of public transit air, and adjacent public transit surfaces may also be considered presumptive sources. Large proportions of detected resistance genes were co-located with mobile genetic elements including plasmids. Biosynthetic gene clusters and city-unique coding sequences were found in the metagenome-assembled genomes. CONCLUSIONS Overall, geographical specificity transcends multiple aspects of the public transit air microbiome, and future efforts on a global scale are warranted to increase our understanding of factors shaping the microbiome of this unique built environment.

95 Lack of Evidence for Reduced Efficacy of Medical Therapy for Heart Failure in Older Adults. Age Ageing 2021.

Abstract
Abstract
Introduction
There are almost a million people with heart failure (HF) in the UK; the incidence increases sharply with age. Older adults receive less evidence-based therapy with few trials specifically examining therapeutic efficacy in older age groups representative of a contemporary UK HF population. Concern that efficacy is less in older adults may underlie under-prescription. With important recent advances in HF therapy, we reviewed the contemporary evidence base for any signal of different efficacy in older adults.
Methods
We reviewed recent RCTs of medical therapy for heart failure alongside meta-analyses updated with recent therapies including Angiotensin-Neprilysin inhibitors and SGLT2 inhibitors. For those trials in which effect size was presented for age subgroups we compared the effect size.
Results
Of 68 randomised controlled trials, 10 presented effect sizes for different age groups. The median average cut-off between younger and older age groups was 66 years (IQR 65 to 72.5 years) and the highest cut-off used was 75 years. The median hazard ratio was 0.77 (IQR 0.67 to 0.80) for the younger age group and 0.76 (IQR 0.73 to 0.88) for the older age group. In 8 of the 10 trials, the effect size in the oldest age group was statistically significant on its own including Sacubitril-Valsartan and Dapagliflozin.
Conclusion
When considering the medical therapeutic armamentarium for heart failure as a totality, there is no evidence it is any less effective in older adults than younger adults. The recent Zannad et al cross-trial analysis supported this showing significant additional life years in the patients over 80 years on HF therapy. Whilst there may be practical and frailty-related reasons for not prescribing life-prolonging therapy, the proportional survival benefits of these medications is similar in older adults. This should be utilised where practically possible and discussed with patients when making an informed choice.

Genetic Determinants of EGFR-Driven Lung Cancer Growth and Therapeutic Response In Vivo. Cancer Discov 2021; 11:1736-1753.

Abstract
In lung adenocarcinoma, oncogenic EGFR mutations co-occur with many tumor suppressor gene alterations; however, the extent to which these contribute to tumor growth and response to therapy in vivo remains largely unknown. By quantifying the effects of inactivating 10 putative tumor suppressor genes in a mouse model of EGFR-driven Trp53-deficient lung adenocarcinoma, we found that Apc, Rb1, or Rbm10 inactivation strongly promoted tumor growth. Unexpectedly, inactivation of Lkb1 or Setd2-the strongest drivers of growth in a KRAS-driven model-reduced EGFR-driven tumor growth. These results are consistent with mutational frequencies in human EGFR- and KRAS-driven lung adenocarcinomas. Furthermore, KEAP1 inactivation reduced the sensitivity of EGFR-driven tumors to the EGFR inhibitor osimertinib, and mutations in genes in the KEAP1 pathway were associated with decreased time on tyrosine kinase inhibitor treatment in patients. Our study highlights how the impact of genetic alterations differs across oncogenic contexts and that the fitness landscape shifts upon treatment. SIGNIFICANCE: By modeling complex genotypes in vivo, this study reveals key tumor suppressors that constrain the growth of EGFR-mutant tumors. Furthermore, we uncovered that KEAP1 inactivation reduces the sensitivity of these tumors to tyrosine kinase inhibitors. Thus, our approach identifies genotypes of biological and therapeutic importance in this disease.This article is highlighted in the In This Issue feature, p. 1601.

Abstract
BACKGROUND Mammalian target of rapamycin (mTOR) inhibitors following liver transplantation (LT) are used to minimize calcineurin inhibitor (CNI)-related nephrotoxicity. Data about metabolic effects of mTOR inhibitors are still limited. AIM This study aims to determine the renal and metabolic effects of different mTOR inhibitor-based protocols in real-life LT patients. METHODS This is a retrospective cohort study of patients treated with mTOR inhibitors after LT. Demographics, treatment protocols, glomerular filtration rate (GFR), and metabolic parameters were collected over a period of 4 years. Initiation of blood pressure (BP), diabetes mellitus, and lipid medications was also noted. RESULTS Fifty-two LT recipients received mTOR inhibitors. GFR improved significantly (by 1.96 mL/min/year), with greater improvement in patients with baseline renal dysfunction (+13.3 mL/min vs +4.5 mL/min at 3 years). Conversion to an mTOR inhibitor during the first post-transplant year resulted in a more durable improvement in GFR (for 4 years vs only 1 year for later conversion).No significant weight gain or new-onset diabetes mellitus was observed. However, there was some increase in total cholesterol (+7 mg/dL) and blood pressure (+2 mm Hg during the third year and +8 mm Hg in the fourth years), followed by initiation of lipid-lowering and BP medications in 25% and 13% of patients, respectively. CONCLUSIONS Treatment with an mTOR inhibitor following LT resulted in improved kidney functions without significant negative metabolic effects such as weight gain or new-onset diabetes mellitus. This makes mTOR inhibitors a valuable immunosuppressive option in the face of the growing incidence of nonalcoholic steatohepatitis as a leading cause for LT.

Abstract
AbstractPurposeLittle is known about the clinical characteristics and motivations for engaging in non-suicide self-injury (NSSI) behaviors in adolescence. The aim of this study was to examine the prevalence, characteristics and functions of NSSI among adolescents in community settings, and to explore risk factors related to this behavior.Subjects and methodsTwo hundred and seventy-five adolescents aged 12 to 17 were recruited randomly from different High Schools in Israel. They completed self-report questionnaires assessing NSSI (Ottawa Self-Injury Inventory), depression (Children's Depression Inventory – CDI) and impulsivity (Barratt Impulsiveness Scale – BIS-II).ResultsIn the past year, 20.7% of the participants reported engaging NSSI at least once. Among them, 42.1% declared they are still engaging in NSSI at the present. Motives for NSSI were internal emotion regulation reasons, external emotion regulation reasons for social influences. In addition, the NSSI group reported significantly higher levels of depressive, impulsivity and suicidal ideations. Depressive symptoms were found as significant predictors of NSSI in the future.Discussion and conclusionsHigh rates of NSSI among community adolescents were found. Depression, impulsivity and suicidal ideation were found significantly related to NSSI. Mental health professionals in schools and in primary care should routinely assess NSSI among adolescents.

Abstract
Abstract
Background
Vernakalant is an antiarrhythmic agent designed for pharmacological conversion of recent onset of atrial fibrillation (AF) with combined action on cardiac potassium and sodium currents mainly concentrated in the atria.
Purpose
SPECTRUM was a post-authorisation safety study of vernakalant, conducted to collect information about real-life conditions of use and appropriate dosing, and to quantify possible medically significant risks associated with the use of vernakalant in real-world clinical practice.
Methods
This prospective and retrospective registry was conducted from Sep 2011 to Apr 2018 in 53 hospitals in EU countries including Austria, Denmark, Finland, Germany, Spain and Sweden. A total of 1,778 patients with 2,009 episodes of recent-onset AF received vernakalant and were followed up for 24 hours after the last infusion or until hospital discharge/end of medical encounter to obtain information on medically significant health outcomes of interest (HOIs, defined as significant hypotension, significant ventricular arrhythmia, significant atrial flutter, significant bradycardia), and serious adverse events (SAEs).
Results
In more than 99% of treatments, vernakalant was used in accordance to the labelled indication for conversion of AF for non-surgery (94.7%) or post-cardiac surgery patients (5.2%). Vernakalant was administered in the emergency department in 64.2% of cases, with a median stay of 7.5 hours and successfully converted 70.2% (95% CI: 68.1–72.2) of patients in the effectiveness analysis population with a median time to conversion of 11 minutes (95% CI: 8.0–27.0). A total of 19 HOIs were reported in 17 patients (0.8%, 95% CI: 0.5– .4%) with individual HOIs ranging from <0.1% to 0.7% suggesting these HOIs are uncommon. Significant bradycardia was the most common HOI observed in 15 patients (0.8%, 95% CI: 0.4–1.2%), with all events occurring within the first two hours (0.8%, 95% CI: 0.4–1.2%). The incidence of significant hypotension was 0.1% (2/2,009), significant atrial flutter (with 1:1 conduction) was 0.1% (2/2,009), and significant ventricular arrhythmia (sustained ventricular tachycardia) was <0.1% (1/2,009). A total of 28 SAEs, including all HOIs, were observed (1.3%, 95% CI: 0.8–1.9%); all patients fully recovered, except one who recovered with sequelae after an SAE of pericardial effusion definitely not related to vernakalant. There were no cases of torsades de pointes, ventricular fibrillation, or deaths reported in the SPECTRUM study.
Conclusion(s)
SPECTRUM is, to our knowledge, the largest drug registry conducted on the cardioversion of recent onset AF. The cumulative data from 2,009 vernakalant treatment episodes demonstrate an incidence of HOIs and SAEs similar or lower to what has been reported in earlier vernakalant IV clinical trials. The observed conversion rate was higher than reported in pivotal trials supporting vernakalant's efficacy and allowing early discharge.

Abstract
Background Epidermal Growth Factor Receptor (EGFR) tyrosine kinase inhibitors (TKIs) like erlotinib are effective for treating patients with EGFR mutant lung cancer; however, drug resistance inevitably emerges. Approaches to combine immunotherapies and targeted therapies to overcome or delay drug resistance have been hindered by limited knowledge of the effect of erlotinib on tumor-infiltrating immune cells. Methods Using mouse models, we studied the immunological profile of mutant EGFR-driven lung tumors before and after erlotinib treatment. Results We found that erlotinib triggered the recruitment of inflammatory T cells into the lungs and increased maturation of alveolar macrophages. Interestingly, this phenotype could be recapitulated by tumor regression mediated by deprivation of the EGFR oncogene indicating that tumor regression alone was sufficient for these immunostimulatory effects. We also found that further efforts to boost the function and abundance of inflammatory cells, by combining erlotinib treatment with anti-PD-1 and/or a CD40 agonist, did not improve survival in an EGFR-driven mouse model. Conclusions Our findings lay the foundation for understanding the effects of TKIs on the tumor microenvironment and highlight the importance of investigating targeted and immuno-therapy combination strategies to treat EGFR mutant lung cancer.

Folliculin regulates mTORC1/2 and WNT pathways in early human pluripotency. Nat Commun 2019; 10:632.

Abstract
To reveal how cells exit human pluripotency, we designed a CRISPR-Cas9 screen exploiting the metabolic and epigenetic differences between naïve and primed pluripotent cells. We identify the tumor suppressor, Folliculin(FLCN) as a critical gene required for the exit from human pluripotency. Here we show that FLCN Knock-out (KO) hESCs maintain the naïve pluripotent state but cannot exit the state since the critical transcription factor TFE3 remains active in the nucleus. TFE3 targets up-regulated in FLCN KO exit assay are members of Wnt pathway and ESRRB. Treatment of FLCN KO hESC with a Wnt inhibitor, but not ESRRB/FLCN double mutant, rescues the cells, allowing the exit from the naïve state. Using co-immunoprecipitation and mass spectrometry analysis we identify unique FLCN binding partners. The interactions of FLCN with components of the mTOR pathway (mTORC1 and mTORC2) reveal a mechanism of FLCN function during exit from naïve pluripotency. The pathways involved in exit from pluripotency in human embryonic stem cells are poorly understood. Here, the authors performed a CRISPR-based screen to identify genes that promote exit from naïve pluripotency and find a role for folliculin (FLCN) by regulating the mTOR and Wnt pathways.

Abstract
Summary1. Coagulation factors levels were measured in 10 normal mothers and in their infants within 15 min of birth and at 48-96 hrs of age.2. In the mothers the levels of fibrinogen (532 mg/%), factors VIII (196%), IX (130%) and X (122%) were elevated; the levels of prothrombin (107%) and factor V (108%) were normal ; and the level of factor XI (69%) was reduced.3. The infants blood examined within 15 min of birth had a slightly elevated factor VIII level (138%), slightly reduced fibrinogen (195 mg/%) and factor V levels (79%), low levels of prothrombin (55%) and factors IX (27%), X (35%) and XI (32%).4. Blood from the infants at 48-96 hrs of age showed little change from the birth levels of factors V (89%), and VIII (116%) and a slight increase in factor XI level (39%). Four of the infants had received vitamin K1 and had higher levels of prothrombin and factors IX and X than the 7 who had not received vitamin K1.5. These results are compared with those of previous studies and the possible mechanisms underlying the changes is discussed.

Abstract
Chemical burns raise diagnostic and treatment issues because they have specific appearances and evolution. Our objective was to study the characteristics of chemical burns and to assess the quality of our treatment. This retrospective observational study examined the records of all patients admitted for chemical burns to the burn treatment center of Saint Louis Hospital in Paris from January 1, 1990, through December 31, 2015. During this period, 162 patients came to our center for chemical burn treatment. Most of them were men (67%). The majority of the burns were caused by alkalis (27%) and resulted from workplace accidents (29%). The average time before consultation was 5.36 days. The areas mainly damaged were the hands (36%) and the burn areas averaged 1.2% of the total body surface area (TBSA). Forty-eight patients had at least one deep patch. In total, 59 patients (36.4%) were hospitalized for an average duration of 4.18 days. Thirty-eight of them underwent surgery. Lastly, 92% of the operations had been anticipated from the first consultation. In our center, the population affected, the circumstances and the topography of our patients' burns were similar to the data from the literature. It appears that the principal specificity of our series is a very low body surface burned. This can be attributed to the prevention measures we have in France and underlines their importance. Only 8% of the patients who had surgery were underestimated or their burns became deeper secondarily. This number is lower than the data from other series.

Treatment motivation among caregivers and adolescents with substance use disorders. J Subst Abuse Treat 2017; 75:10-16.

Abstract
Substance use disorders (SUDs) in adolescence have negative long-term health effects, which can be mitigated through successful treatment. Caregivers play a central role in adolescent treatment involvement; however, studies have not examined treatment motivation and pressures to enter treatment in caregiver/adolescent dyads. Research suggests that internally motivated treatment (in contrast to coerced treatment) tends to lead to better outcomes. We used Self-determination theory (SDT) to examine intersecting motivational narratives among caregivers and adolescents in SUD treatment. Relationships between motivation, interpretation of caregiver pressures, adolescent autonomy, and relatedness were also explored. Adolescents in SUD treatment and their caregivers (NDyads=15) were interviewed about treatment experiences. Interviews were coded for treatment motivation, including extrinsic (e.g., motivated by punishment), introjected (e.g., motivated by guilt), and identified/integrated motivation (e.g., seeing a behavior as integral to the self). Internalization of treatment motivation, autonomy support/competence (e.g., caregiver support for adolescent decisions), and relatedness (e.g., acceptance and support) were also coded. Four dyadic categories were identified: agreement that treatment was motivated by the adolescent (intrinsic); agreement that treatment was motivated by the caregiver (extrinsic); agreement that treatment was motivated by both, or a shift towards adolescent control (mixed/transitional); and disagreement (adolescents and caregivers each claimed they motivated treatment; conflicting). Autonomy support and relatedness were most prominent in intrinsic dyads, and least prominent in extrinsic dyads. The mixed/transitional group was also high in autonomy support and relatedness. The extrinsic group characterized caregiver rules as an unwelcome mechanism for behavioral control; caregivers in the other groups saw rules as a way to build adolescent competence and repair relationships, and adolescents saw rules as indicating care rather than control. Adolescents with intrinsic motivations were the most engaged in treatment. Results suggest the importance of intrinsically motivated treatment, and highlight autonomy support and relatedness as mechanisms that might facilitate treatment engagement.

[Pseudotumor cerebri due to taking minocycline]. REVUE MEDICALE DE BRUXELLES 2017; 38:169-172. [PMID: 28653520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Indexed: 06/07/2023]
Abstract
The cerebral pseudotumor (PTC) is defined by the increase in cerebrospinal fluid (CSF) pressure, a normal composition of the latter in the absence of identified intracranial structural abnormalities, in particular by neuroimaging. The pathophysiology of PTC is poorly understood although its diagnostic criteria are well established. Drugs such as minocycline, tetracycline and doxycycline have been repeatedly implicated as a causative factor in PTC. The prognosis of PTC related to minocycline, reported in the literature is quite variable. Some authors suggest a benign condition with spontaneous healing by stopping the antibiotic, while others report permanent loss of vision. A 12-year-old girl is admitted to the emergency room for progressively progressive pulsatile temporal headaches associated with diplopia. The patient reported the use of minocycline 50 mg / d for five months, prescribed by her attending physician as part of an acne treatment. PTC will be demonstrated by severe papillary edema and cerebral NMR will demonstrate an enlargement of the subarachnoid space around the optic nerves. After three lumbar punctures, the condition of the patient stabilized and there was a marked improvement in headache despite the persistence of bilateral papillary edema. This work describes a clinical case of PTC induced by the use of minocycline and reviews the physiopathology, the diagnosis and the management of this one.

Abstract
This paper summarizes a current study examining the availability, appropriateness and acceptability of a technologically dependable healthcare provision to both service users and staff. An interface between the Electronic Patient Record (EPR) and future home care technology (Telecare) is suggested in the form of a ‘technology prescription’. It is argued that appropriately prescribed technology will enable people to benefit from a modern, evidence-based service, which promotes a proactive means of addressing and preventing future health and care needs. The paper argues that technological innovations in care must not be perceived as a threat to the partnerships necessary in achieving maximum health gains, but rather be an aid to a patient centred clinical encounter.

Abstract
In patients with WPW syndrome the maximal ventricular rate attained during ectopic rapid supraventricular thythms depended on the type of arrhythmia as well as on the physiological properties of the AP. During reciprocating tachycardias the impulse is almost invariably conducted to the ventricles through the AV node. Therefore, the maxiaml ventricular rate is a function of the AV nodal ERP. On the other hand, when atrial flutter or atrial fibrillation were present the ventricular rate could be moderately elevated (when the ERP of the AP was longer than that of the AV node) or very rapid where the ERP of the AP was significantly short. Therefore, from the electrophysiological viewpoint, the AP appears to behave as His-Purkinje tissue in some cases and as ordinary artrial muscle in other patients. These assumptions await further documentation.

Abstract
OBJECTIVE To investigate whether an increase in daily tooth brushing frequency in children was predicted by either a) having a strong intention to brush twice a day or b) their parents receiving information about their new caries experience. BASIC RESEARCH DESIGN Secondary data analyses were conducted on two waves of data from the Aban Aya Youth Project and the Iowa Fluoride Study. PARTICIPANTS The Aban Aya study included 576 10- and 11-year olds from Chicago, Illinois. The Iowa Fluoride Study included a convenience sample of 709 babies born in Iowa. The present study includes those children at age 9. MAIN OUTCOME MEASURES In both studies, reported daily tooth brushing frequency was assessed twice six months apart. RESULTS In the Aban Aya data, compared with children with a weak intention at wave 1 to brush twice a day, children with a strong intention to brush twice a day were more likely to increase their brushing frequency by wave 2, OR 7.0, 95%CI 1.5,32.9. In the Iowa Fluoride Study, compared with children who did not have new caries at wave 1, children who had new caries experience were less likely to increase their brushing frequency by wave 2, OR 0.4, 95%CI 0.2,0.9. CONCLUSIONS Strengthening intention to brush twice a day might increase children's brushing frequency. However, simply providing parents with information about new caries probably will not. Future studies should assess tooth brushing frequency, habit strength, intention, and situational cues at closely-spaced waves.

Abstract
Anorexia nervosa (AN) and related eating disorders are complex, multifactorial neuropsychiatric conditions with likely rare and common genetic and environmental determinants. To identify genetic variants associated with AN, we pursued a series of sequencing and genotyping studies focusing on the coding regions and upstream sequence of 152 candidate genes in a total of 1205 AN cases and 1948 controls. We identified individual variant associations in the Estrogen Receptor-ß (ESR2) gene, as well as a set of rare and common variants in the Epoxide Hydrolase 2 (EPHX2) gene, in an initial sequencing study of 261 early-onset severe AN cases and 73 controls (P=0.0004). The association of EPHX2 variants was further delineated in: (1) a pooling-based replication study involving an additional 500 AN patients and 500 controls (replication set P=0.00000016); (2) single-locus studies in a cohort of 386 previously genotyped broadly defined AN cases and 295 female population controls from the Bogalusa Heart Study (BHS) and a cohort of 58 individuals with self-reported eating disturbances and 851 controls (combined smallest single locus P<0.01). As EPHX2 is known to influence cholesterol metabolism, and AN is often associated with elevated cholesterol levels, we also investigated the association of EPHX2 variants and longitudinal body mass index (BMI) and cholesterol in BHS female and male subjects (N=229) and found evidence for a modifying effect of a subset of variants on the relationship between cholesterol and BMI (P<0.01). These findings suggest a novel association of gene variants within EPHX2 to susceptibility to AN and provide a foundation for future study of this important yet poorly understood condition.

Abstract
A discussion of alcohol, drugs and sexuality is an important part of routine health advice and guidance for adolescents. It is important for providers to use a systematic approach that includes building rapport and asking standard screening questions using non-judgmental and gender-neutral language. This strategy minimizes the chance of omitting key questions and increases efficiency of the interview, while being respectful of the adolescent's autonomy and choices. During adolescence, some of the health visit will occur with the adolescent alone. As part of that transition, clinicians should explain conditional confidentiality to both the adolescent and the parent. When discussing alcohol and drug use, clinicians should have information about the epidemiologic patterns in their practice area, use standard tools for screening and be familiar with local resources for treatment. Similarly, when discussing sexuality, clinicians should use a standard approach such as the "5 P's." Clinicians can provide adolescents with a safe environment to share sensitive information and risk taking behaviors using a clear and consistent approach.
