RESUMO
BACKGROUND AND AIMS: The diagnostic and therapeutic strategy in severe lower gastrointestinal bleeding (LGIB) varies depending on the patient's clinical situation. Actual clinical practice guidelines propose different management strategies. We aim to know the attitude of the gastroenterologists from different hospitalary centers in the management of this entity. METHODS: Descriptive and observational study using an on-line questionnaire, addressed to gastroenterologists in Spain and Latin America, in December 2021. RESULTS: We included 281 anonymous questionnaires of gastroenterologists from Spain and Latin America. Diagnostic and therapeutic management of severe LGIB was heterogeneous among the participants. Regarding to the first diagnostic modalities they showed variability between performing computed tomography angiography (CTA) (44.5%), gastroscopy (33.1%), colonoscopy (20.6%) and arteriography (1.1%). The therapeutic attitude after a positive CTA mostly varied between performing arteriography (38.1%) and colonoscopy (44.1%). If negative CTA, in the majority of cases a gastroscopy was performed. If the patient needed intensive critical unit (ICU) care and to undergo colonoscopy, most participants performed an urgent colonoscopy (<24h) (31% always, 43.4% in most cases); while if the patient did not require ICU admission this percentage was lower (10% always, 33.8% in most cases). The 40.9% of the participants admitted having doubts about the management of this patients and the 98.2% considered the need for a creation of an action protocol. CONCLUSIONS: There is a high interhospitalary variability on the management of severe lower gastrointestinal bleeding among gastroenterologists. It is necessary to unify the diagnostic and therapeutic management of this pathology.

The case was a 53-year-old male with a history of acute pancreatitis of biliary origin, and subsequent laparoscopic cholecystectomy, currently hospitalized due to a diagnosis of acute pancreatitis. Seventy-two hours after the onset of symptoms he had fever, uncontrolled pain, and elevated inflammatory markers. An abdominal computed tomography (CT) scan revealed an aerial collection at the pancreatic gland suggestive of emphysematous pancreatitis. Proteus vulgaris was isolated from pancreatic puncture and blood cultures. The patient developed septic shock, which required admission to the intensive care unit. Septic shock was initially controlled by percutaneous drainage. However, surgical debridement was also necessary in the following days.

A 66-year-old male patient with no specific prior medical history consulted due to constipation without other associated symptoms. A colonoscopy was performed and multiple pseudonodular lesions were detected from the sigmoid to splenic angle in the form of air bubbles with normal-appearing mucosa and a preserved vascular pattern. Gas was released when the biopsies were being taken. An abdominal computed tomography (CT) scan was performed due to the suspicion of an idiopathic or primary intestinal pneumatosis, in which the findings confirmed the diagnosis.

BACKGROUND: To analyse the reliability, variance and execution time of the Extended Timed Up and Go (Extended TUG) test in three age groups of elderly participants (G1: 55-64 years; G2: 65-74 years; G3: 75-85 years). METHODS: An analytical cross-sectional study of 114 recruited participants (63 women) of average age 70.17 (± 7.3) years was undertaken. Each participant performed the Extended TUG three consecutive times, with a rest break between tests of 120 s. Both the intragroup and intergroup reliability of the measurements in the Extended TUG were analysed. RESULTS: The reliability of the Extended TUG test is excellent for the first and second decades but drops down to good for the third decade. Specifically, intragroup reliability ranged from 0.784 for G3 to 0.977 for G1 (G2 = 0.858). Intergroup reliability, compared with intragroup reliability, was slightly lower, ranging between 0.779 for G3 and 0.972 for G1 (G2 = 0.853). CONCLUSION: The reliability of the Extended TUG test progressively decreases with increasing age, being excellent for the younger age groups and good for the oldest age group.

Cathepsin K (CTSK) is a secreted protease that plays an essential role in osteoclastic bone resorption and osteoporotic bone loss. We have previously shown that activator protein 1 (AP-1) stimulates CTSK promoter activity and that proximal nuclear factor of activated T cells cytoplasmic 1 (NFATc1)-binding sites play a major role in the stimulation of CTSK gene expression by receptor activator of NFκB ligand (RANKL). In the present study, we have extended these observations and further dissected the effects of transcription factors involved in the regulation of CTSK gene expression. Our aim was to investigate the cooperative interplay among transcription factors AP-1, microphthalmia-associated transcription factor (Mitf), and NFATc1, and the consequent regulatory effects on CTSK transcription. Experiments were carried out in RAW 264.7 cells, which can be readily differentiated to osteoclasts upon RANKL stimulation. Our data show that AP-1, Mitf, and NFATc1 are capable of independently stimulating CTSK promoter activity. A combination of any two factors further enhances CTSK promoter activity, with the combination of AP-1 (c-fos/c-jun) and NFATc1 inducing the largest increase. We further identify a synergistic effect when all three factors cooperate intimately at the proximal promoter region, yielding maximal transcriptional upregulation of the CTSK promoter. RANKL induces temporal localization of AP-1 and NFATc1 to the CTSK promoter. These results suggest that the interaction of multiple transcription factors mediate a maximal response to RANKL-induced CTSK gene expression.

BACKGROUND: Short-term and mid-term comparison of the efficacy of a multimodal program that incorporates a therapeutic workout program, medication review, diet adjustment and health education, in comparison to the standard medical practice in the improvement of the neuromuscular and physiological condition. Furthermore, it is intended to analyse the maintenance of these effects in a long-term follow-up (12 months) from the onset of the intervention. METHODS: A randomized clinical trial of elderly frail patients drawn from the Clinical Management Unit "Tiro de Pichón", Health District of Malaga, will be included in the study (after meeting the inclusion / exclusion criteria) will be randomized in two groups: a control group that will undergo an intervention consistent of medication review + diet adjustment + health education (regular workout recommendations within a complete advice on healthy lifestyles) and an experimental group whose intervention will consist of a multimodal treatment: therapeutic workout program+ medication review+ diet adjustment + health education. The sociodemographic, clinical and tracing variables will be reflected at the beginning of the study. In addition, the follow-up variables will be gathered at the second and sixth months after the beginning of the treatment and at the third and sixth months after the treatment (follow-up). The follow-up variables that will be measured are: body mass index, general health condition, fatigue, frailty, motor control, attention- concentration- memory, motor memory, spatial orientation, grip strength, balance (static, semi-dynamic), gait speed and metabolomics. A descriptive analysis of the sociodemographic variables of the participants will be conducted. One-Factor ANOVA will be used for the Within-Subject analysis and as for the Between-Subject analysis, the outcome variables between both the groups in each moment of the data collection will be compared. DISCUSSION: A multimodal program that incorporates a therapeutic workout program, medication review, diet adjustment and health education may be effective treatment to reduce the functional decline in elderly. The results of the study will provide information on the possible strengths and benefits in multimodal program in elderly. TRIAL REGISTRATION: ClinicalTrials.gov NCT02772952 registered May 2017.

AIM: The study aims to analyse the efficacy of massage therapy and kinesitherapy applied by parents of premature infants admitted to hospital. BACKGROUND: Premature newborns suffer early somatic deprivation that has adverse effects on their growth and development and that also has a negative impact on the emotional state of their parents. Massage therapy and kinesitherapy is beneficial in alleviating somatic deficit and facilitates the bond between parents and newborns. DESIGN: A quasi-experimental community intervention trial will be conducted in a neonatology unit. METHODS: This study will compare the benefits of a 15-min massage protocol applied by parents with the usual medical and nursing care given by neonatal units for premature babies. The evaluation of neuromotor development will take place through the Spanish Premie-Neuro scale. The determination of weight, size, and head circumference will be based on the unit's usual procedures. DISCUSSION: If the implementation of a massage therapy and kinesitherapy protocol is effective in promoting the growth and development of hospitalized premature infants, the results of this study could give an impetus for the inclusion of somatic stimulation in the usual nursing care given for preterm infants. IMPACT: Prematurity and its associated morbidity pose a major global public health problem. Somatic and kinaesthetic stimulation has beneficial effects on anthropometric and neuromotor development in preterm infants. The results will have a positive impact on premature neonates and their families, both during the hospitalization, and a positive socio-economic effect throughout their lives (education, work, disability). TRIAL REGISTRATION: NCT03704012.

BACKGROUND: To determine whether there is greater employee satisfaction in organisations that have made more progress in implementation of the European Foundation for Quality Management (EFQM) model. METHODS: A series of cross-sectional studies (one for each assessment cycle) comparing staff satisfaction survey results between groups of healthcare organisations by degree of implementation of the EFQM model (assessed in terms of external recognition of management quality in each organisation). SETTING: 30 healthcare organisations including hospitals, primary care and mental health providers in Osakidetza, the Basque public health service. PARTICIPANTS: Employees of 30 Osakidetza organisations. INTERVENTION: Progress in implementation of EFQM model. MAIN OUTCOME MEASURES: Scores in 9 dimensions of employee satisfaction from questionnaires administered in healthcare organisations in 4 assessment cycles between 2001 and 2010. RESULTS: Comparing satisfaction results in organisations granted Gold or Silver Q Awards and those without this type of external recognition, we found statistically significant differences in the dimensions of training and internal communication. Then, comparing recipients of Gold Q Awards with those with no Q Certification, differences in leadership style and in policy and strategy also emerged as significant. CONCLUSIONS: Progress of healthcare organisations in the implementation of the EFQM Excellence Model is associated with increases in their employee satisfaction in dimensions that can be managed at the level of each organisation, while dimensions in which no statistically significant differences were found represent common organisational elements with little scope for self-management.

RESUMO
Background: Sarcomeric hypertrophic cardiomyopathy (HCM) must be differentiated from phenotypically similar conditions because clinical management and prognosis may greatly differ. Patients with unexplained left ventricular hypertrophy require an early, confirmed genetic diagnosis through diagnostic or predictive genetic testing. We tested the feasibility and practicality of the application of a 17-gene next-generation sequencing (NGS) panel to detect the most common genetic causes of HCM and HCM phenocopies, including treatable phenocopies, and report detection rates. Identification of transthyretin cardiac amyloidosis (ATTR-CA) and Fabry disease (FD) is essential because of the availability of disease-specific therapy. Early initiation of these treatments may lead to better clinical outcomes. Methods: In this international, multicenter, cross-sectional pilot study, peripheral dried blood spot samples from patients of cardiology clinics with an unexplained increased left ventricular wall thickness (LVWT) of ≥13 mm in one or more left ventricular myocardial segments (measured by imaging methods) were analyzed at a central laboratory. NGS included the detection of known splice regions and flanking regions of 17 genes using the Illumina NextSeq 500 and NovaSeq 6000 sequencing systems. Results: Samples for NGS screening were collected between May 2019 and October 2020 at cardiology clinics in Colombia, Brazil, Mexico, Turkey, Israel, and Saudi Arabia. Out of 535 samples, 128 (23.9%) samples tested positive for pathogenic/likely pathogenic genetic variants associated with HCM or HCM phenocopies with double pathogenic/likely pathogenic variants detected in four samples. Among the 132 (24.7%) detected variants, 115 (21.5%) variants were associated with HCM and 17 (3.2%) variants with HCM phenocopies. Variants in MYH7 (n=60, 11.2%) and MYBPC3 (n=41, 7.7%) were the most common HCM variants. The HCM phenocopy variants included variants in the TTR (n=7, 1.3%) and GLA (n=2, 0.4%) genes. The mean (standard deviation) ages of patients with HCM or HCM phenocopy variants, including TTR and GLA variants, were 42.8 (17.9), 54.6 (17.0), and 69.0 (1.4) years, respectively. Conclusions: The overall diagnostic yield of 24.7% indicates that the screening strategy effectively identified the most common forms of HCM and HCM phenocopies among geographically dispersed patients. The results underscore the importance of including ATTR-CA (TTR variants) and FD (GLA variants), which are treatable disorders, in the differential diagnosis of patients with increased LVWT of unknown etiology.
RESUMO
Since early 2020, different studies have shown an increased prevalence of COVID-19 and poorer prognosis in older adults with cardiovascular comorbidities. This study aimed to assess the impact of heart failure (HF) on cardiovascular complications, intensive care unit (ICU) admissions, and in-hospital mortality in patients hospitalized with COVID-19. The CARDIO COVID 19-20 registry includes 3260 hospitalized patients with a COVID-19 serological diagnosis between May 2020 and June 2021 from Latin American countries. A history of HF was identified in 182 patients (5.6%). In patients with and without previous HF, the incidence of supraventricular arrhythmia was 16.5% vs. 6.3%, respectively (p = 0.001), and that of acute coronary syndrome was 7.1% vs. 2.7%, respectively (p = 0.001). Patients with a history of HF had higher rates of ICU admission (61.5% vs. 53.1%, respectively; p = 0.031) and in-hospital mortality (41.8% vs. 24.5%, respectively; p = 0.001) than patients without HF. Cardiovascular mortality at discharge (42.1% vs. 18.5%, respectively; p < 0.001) and at 30 days post-discharge (66.7% vs. 18.0%, respectively) was higher for patients with a history of HF than for patients without HF. In patients hospitalized with COVID-19, previous history of HF was associated with a more severe cardiovascular profile, with increased risk of cardiovascular complications, and poor in-hospital and 30-day outcomes.
RESUMO
BACKGROUND: About 80% of cardiovascular diseases (including heart failure [HF]) occur in low-income and developing countries. However, most clinical trials are conducted in developed countries. HYPOTHESIS: The American Registry of Ambulatory or Acutely Decompensated Heart Failure (AMERICCAASS) aims to describe the sociodemographic characteristics of HF, comorbidities, clinical presentation, and pharmacological management of patients with ambulatory or acutely decompensated HF in America. METHODOLOGY: Descriptive, observational, prospective, and multicenter registry, which includes patients >18 years with HF in an outpatient or hospital setting. Collected information is stored in the REDCap electronic platform. Quantitative variables are defined according to the normality of the variable using the Shapiro-Wilk test. RESULTS: This analysis includes data from the first 1000 patients recruited. 63.5% were men, the median age of 66 years (interquartile range 56.7-75.4), and 77.6% of the patients were older than 55 years old. The percentage of use of the four pharmacological pillars at the time of recruitment was 70.7% for beta-blockers (BB), 77.4% for angiotensin-converting enzyme inhibitor (ACEI)/angiotensin II receptor blocker (ARB II)/angiotensin receptor-neprilysin inhibitor (ARNI), 56.8% for mineralocorticoid receptor antagonists (MRA), and 30.7% for sodium-glucose cotransporter type-2 inhibitors (SGLT2i). The main cause of decompensation in hospitalized patients was HF progression (64.4%), and the predominant hemodynamic profile was wet-warm (68.3%). CONCLUSIONS: AMERICCAASS is the first continental registry to include hospitalized or outpatient patients with HF. Regarding optimal medical therapy, approximately a quarter of the patients still need to receive BB and ACEI/ARB/ARNI, less than half do not receive MRA, and more than two-thirds do not receive SGLT2i.

BACKGROUND: Ulcerative proctitis (UP) can have a milder, less aggressive course than left-sided colitis or extensive colitis. Therefore, immunosuppressants tend to be used less in patients with this condition. Evidence, however, is scarce because these patients are excluded from randomised controlled clinical trials. Our aim was to describe the characteristics of patients with refractory UP and their disease-related complications, and to identify the need for immunosuppressive therapies. METHODS: We identified patients with UP from the prospective ENEIDA registry sponsored by the GETECCU. We evaluated socio-demographic data and complications associated with immunosuppression. We defined immunosuppression as the use of immunomodulators, biologics and/or small molecules. We used logistic regression to identify factors associated with immunosuppressive therapy. RESULTS: From a total of 34,716 patients with ulcerative colitis, we identified 6281 (18.1%) with UP; mean ± SD age 53 ± 15 years, average disease duration of 12 ± 9 years. Immunosuppression was prescribed in 11% of patients, 4.2% needed one biologic agent and 1% needed two; 2% of patients required hospitalisation, and 0.5% underwent panproctocolectomy or subtotal colectomy. We identified 0.2% colorectal tumours and 5% extracolonic tumours. Patients with polyarthritis (OR 3.56, 95% CI 1.86-6.69; p < 0.001) required immunosuppressants. CONCLUSIONS: Among patients with refractory UP, 11% required immunosuppressant therapy, and 4.2% required at least one biologic agent.

OBJECTIVE: Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a clinical condition found in patients who have received intravenous or oral bisphosphonate therapy for various diseases related to bone. This report describes a novel treatment of BRONJ using autologous bone marrow stem cells, platelet-rich plasma, beta tricalcium phosphate, and demineralized bone matrix. STUDY DESIGN: We report a 71-year-old woman with history of multiple myeloma treated with intravenous zoledronic acid during 4 years. After a tooth extraction, the patient presented with a painful BRONJ lesion with no healing wound and cortical bone exposure. The patient was surgically managed with a standardized protocol of autologous stem cell therapy combining bone marrow harvest, cell concentration procedures, and intraoral surgery. RESULTS: CT scan performed 6 months later showed improvement of bone and concentric ossification. Cellular therapy might be considered a new strategy to heal BRONJ lesions.

OBJECTIVE: Generate recommendations for the diagnosis, management, and follow-up of chronic hyperkalemia. METHOD: This consensus was made by nephrologists and cardiologists following the GRADE methodology. RESULTS: Chronic hyperkalemia can be defined as a biochemical condition with or without clinical manifestations characterized by a recurrent elevation of serum potassium levels that may require pharmacological and or non-pharmacological intervention. It can be classified as mild (K+ 5.0 to < 5.5 mEq/L), moderate (K+ 5.5 to 6.0 mEq/L) or severe (K+ > 6.0 mEq/L). Its incidence and prevalence have yet to be determined. Risk factors: chronic kidney disease, chronic heart failure, diabetes mellitus, age ≥ 65 years, hypertension, and drugs that inhibit the renin angiotensin aldosterone system (RAASi), among others. There is no consensus for the management of chronic hyperkalemia. The suggested pattern for patients is to identify and eliminate or control risk factors, provide advice on potassium intake and, for whom it is indicated, optimize RAASi therapy, administer oral potassium binders and correct metabolic acidosis. CONCLUSIONS: The recommendation is to pay attention to the diagnosis, management, and follow-up of chronic hyperkalemia, especially in patients with risk factors.
OBJETIVO: Generar recomendaciones para el diagnóstico, el manejo y el seguimiento de la hiperkalemia crónica. MÉTODO: Este consenso fue realizado por nefrólogos y cardiólogos siguiendo la metodología GRADE. RESULTADOS: La hiperkalemia crónica puede definirse como una condición bioquímica, con o sin manifestaciones clínicas, caracterizada por una elevación recurrente de las concentraciones séricas de potasio que puede requerir una intervención farmacológica, no farmacológica o ambas. Puede clasificarse en leve (K+ 5,0 a < 5,5 mEq/l), moderada (K+ 5,5 a 6,0 mEq/l) o grave (K+ > 6,0 mEq/l). Su incidencia y prevalencia no han sido claramente determinadas. Se consideran factores de riesgo la enfermedad renal crónica, la insuficiencia cardiaca crónica, la diabetes mellitus, la edad ≥ 65 años, la hipertensión arterial y el tratamiento con inhibidores del sistema renina-angiotensina-aldosterona (iSRAA), entre otros. No hay consenso sobre el manejo de la hiperkalemia crónica. Se sugiere identificar y eliminar o controlar los factores de riesgo, brindar asesoramiento sobre la ingesta de potasio y, para quien esté indicado, optimizar la terapia con iSRAA, administrar aglutinantes orales del potasio y corregir la acidosis metabólica. CONCLUSIONES: Se recomienda prestar atención al diagnóstico, el manejo y el seguimiento de la hiperkalemia crónica, en especial en los pacientes con factores de riesgo.

INTRODUCTION: The National Registry of Hip Fractures (RNFC) facilitates knowledge of hip fracture process in Spain to clinicians and managers and is useful to the reduction of the results variability, including the destination at discharge after the hip fracture. OBJECTIVE: The aim of this study was to describe functional recovery units (URFs) use for patients with hip fracture included in the RNFC and to compare the results of the different autonomous communities (AC). MATERIAL AND METHODS: An observational, prospective and multicenter study of several hospitals in Spain. Data from a RNFC cohort of patients admitted with hip fracture between 2017 and 2022 were analyzed, focusing on the location at discharge of the patients, specifically on transfer to the URF. RESULTS: 52,215 patients from 105 hospitals were analyzed, 9540 patients (18.1%) were transferred to URF upon discharge and 4595 (8.8%) remained in these units 30 days later, with a variable distribution between the different AC (0-49%) and variability of results in patients not recovering ambulation at 30 days (12.2-41.9%). CONCLUSIONS: There is in orthogeriatric patient an unequal availability and use of URFs between different autonomous communities. The study of the usefulness of this resource can be of great value for decision-making in health policies.

The main purpose of this study was to adapt the Student Adaptation to College Questionnaire (SACQ) for use with Spanish students and to examine the psychometric properties of the scores. The adapted version of the scale was applied to a sample of 300 first-year university students. The internal consistency of the full scale and of the subscales was adequate, although the structure of the scale, analyzed by confirmatory factor analysis, did not fit satisfactorily to the four-factor model proposed by Baker and Siryk. The goodness of fit of each of four one-factor models, corresponding to each subscale, was tested separately in order to propose a short form of the scale. The resulting scale, comprising 50 items, shows high internal consistency and the relationships between its dimensions are consistent with those obtained in other studies.

Growth alterations have been described in patients operated on for oral clefts. The purpose of this work was to analyze the craniofacial and palate morphology and dimensions of young adults operated on for oral clefts in early childhood in Spain. Eighty-three patients from eight different hospitals were divided into four groups based on their type of cleft: cleft lip (CL, n = 6), unilateral cleft lip and palate (UCLP, n = 37), bilateral cleft lip and palate (BCLP, n = 16), and cleft palate only (CPO, n = 24). A control group was formed of 71 individuals. Three-dimensional (3D) digital models were obtained from all groups with an intraoral scanner, together with cephalometries and frontal, lateral, and submental facial photographs. Measurements were obtained and analyzed statistically. Our results showed craniofacial alterations in the BCLP, UCLP, and CPO groups with an influence on the palate, maxilla, and mandible and a direct impact on facial appearance. This effect was more severe in the BCLP group. Measurements in the CL group were similar to those in the control group. Cleft characteristics and cleft type seem to be the main determining factors of long-term craniofacial growth alterations in these patients. Prospective research is needed to clearly delineate the effects of different treatments on the craniofacial appearance of adult cleft patients.

Bcl-2 is an anti-apoptotic member of the Bcl-2 family of proteins that protects cells from apoptosis induced by a large variety of stimuli. The protein BMRP (MRPL41) was identified as a Bcl-2 binding partner and shown to have pro-apoptotic activity. We have performed deletion mutational analyses to identify the domain(s) of Bcl-2 and BMRP that are involved in the Bcl-2/BMRP interaction, and the region(s) of BMRP that mediate its pro-apoptotic activity. The results of these studies indicate that both the BH4 domain of Bcl-2 and its central region encompassing its BH1, BH2, and BH3 domains are required for its interaction with BMRP. The loop region and the transmembrane domain of Bcl-2 were found to be dispensable for this interaction. The Bcl-2 deletion mutants that do not interact with BMRP were previously shown to be functionally inactive. Deletion analyses of the BMRP protein delimited the region of BMRP needed for its interaction with Bcl-2 to the amino-terminal two-thirds of the protein (amino acid residues 1-92). Further deletions at either end of the BMRP(1-92) truncated protein resulted in lack of binding to Bcl-2. Functional studies performed with BMRP deletion mutants suggest that the cell death-inducing domains of the protein reside mainly within its amino-terminal two-thirds. The region of BMRP required for the interaction with Bcl-2 is very relevant for the cell death-inducing activity of the protein, suggesting that one possible mechanism by which BMRP induces cell death is by binding to and blocking the anti-apoptotic activity of Bcl-2.

Ingestion of excess vitamin A appears to correlate with an increased fracture risk, an outcome that is likely mediated by retinoic acids (RAs); these are vitamin A metabolites that have dramatic effects on skeletal development. We studied the impacts of RA and isoform-specific RA receptor (RAR) agonists (α, ß, and γ) on osteoclast formation (osteoclastogenesis) in two model systems: RAW264.7 cells and murine bone marrow-derived monocytes. The pan-RAR agonists, all-trans and 9-cis RA, inhibited receptor activator of nuclear factor kappa B ligand (RANKL)-mediated osteoclast differentiation in a concentration-dependent manner. Isoform-specific RAR agonists (α, ß, and γ) also inhibited osteoclastogenesis, with the RARα agonist producing the most consistent reductions in both osteoclast number and size and total area covered. Inhibition of osteoclastogenesis correlated with reductions in expression, DNA binding, and nuclear abundance of nuclear factor of activated T cells c1 (NFATc1), a transcription factor critical for osteoclastogenesis. The upregulation of three NFATc1-responsive genes, cathepsin K, dendritic cell-specific transmembrane protein and osteoclast-associated receptor were similarly reduced following RA or RAR agonist exposure. These results suggest that RA blocks in vitro RANKL-mediated osteoclastogenesis by decreasing NFATc1 function.
