Meta-analysis of genome-wide association studies for cancer therapy-related cardiovascular dysfunction and functional mapping highlight an intergenic region close to TP63.

Cancer therapy-related cardiac dysfunction (CTRCD), which commonly includes left ventricular dysfunction and heart failure, is the main adverse effect of anticancer therapy. In recent years several candidate genes studies and genome-wide association studies have identified common genetic variants associated with CTRCD, but evidence remains limited and few genetic variants are robust. A genome-wide meta-analysis of CTRCD was performed with 852 oncology patients receiving cancer therapy. DNA samples were genotyped and imputed to perform a GWAS meta-analysis for case-control (N = 852 (380 cases and 472 controls) and extreme phenotypes (N = 618 (78 cases and 472 controls) looking for genetic variants that predispose to CTRCD. The results were validated in a replicate cohort of 1,191 oncology patients (245 cases and 946 controls). Functional mapping of the replicated loci was then performed. The meta-analysis showed 9 and 17 loci suggestively associated (P-value < 1 × 10-5) with CTRCD in case-control and extreme phenotypes analyses, respectively. The 3q28 locus (rs rs7652759, P = 5.64 × 10-6) in the case-control analysis was the strongest signal, with up to 64 SNPs above the suggestive significance threshold. The rs7652759, an intergenic variant between TPRG1 and TP63 genes, was the only variant validated in the replication cohort (P-value = 0.01). Functional mapping of this significant locus revealed up to 5 new genes potentially involved in the CTRCD. We identified the intergenic region near TP63 as a novel CTRCD susceptibility locus. In the future, the genotyping of these markers could be considered in new CTRCD risk scores to improve preventive strategies in cardio-oncology.

Examining the Role of Cultural and Family Factors in Substance Use Risk Among Indian American Youth.

INTRODUCTION: Although Indian Americans constitute the second-largest immigrant group in the United States, there is a paucity of information about Indian American youth, particularly with respect to substance use risk. We examined the relationship of social factors to permissive substance use beliefs (a proxy for substance use risk since they can lead to adulthood substance use and misuse) and family functioning. METHODS: The study used structural equation modeling to examine the prevalence of permissive substance use beliefs in a sample of Indian American youth ages 12-17 (N = 223) and examined the degree to which discrimination, bicultural identity integration, and endorsement of the model minority stereotype were associated with permissive substance use beliefs. RESULTS: Findings suggest that bicultural identity integration (B = 0.267 [SE = 0.112], p = 0.01) and discrimination (B = 0.294 [SE = 0.087], p = 0.001) are positively associated with permissive substance use beliefs. Bicultural identity integration (B = 0.415 [SE = 0.090], p = 0.0001) was positively associated with family support (B= -0.329 [SE = 0.108], p = 0.002) which, in turn, was associated with less permissive substance use beliefs. In contrast, endorsement of the model minority stereotype (B = 0.351 [SE = 0.090], p = 0.001) was positively associated with family closeness (B = 0.232 [SE = 0.927], p = 0.01) which, in turn, was associated with family support and then with less permissive substance use beliefs. CONCLUSIONS: Discrimination and bicultural identity integration emerged as key constructs related to substance use risk among Indian American youth. These youth could benefit from culturally appropriate prevention programming that addresses the negative impact of discrimination and its effect on permissive substance use beliefs and highlights protective factors.

Design, Synthesis, and Structure-Activity Relationship Studies of New Quinone Derivatives as Antibacterial Agents.

Resistance to antibacterial agents is a growing global public health problem that reduces the efficacy of available antibacterial agents, leading to increased patient mortality and morbidity. Unfortunately, only 16 antibacterial drugs have been approved by the FDA in the last 10 years, so it is necessary to develop new agents with novel chemical structures and/or mechanisms of action. In response to this, our group takes up the challenge of designing a new family of pyrimidoisoquinolinquinones displaying antimicrobial activities against multidrug-resistant Gram-positive bacteria. Accordingly, the objective of this study was to establish the necessary structural requirements to obtain compounds with high antibacterial activity, along with the parameters controlling antibacterial activity. To achieve this goal, we designed a family of compounds using different strategies for drug design. Forty structural candidates were synthesized and characterized, and antibacterial assays were carried out against high-priority bacterial pathogens. A variety of structural properties were modified, such as hydrophobicity and chain length of functional groups attached to specific carbon positions of the quinone core. All the synthesized compounds inhibited Gram-positive pathogens in concentrations ranging from 0.5 to 64 µg/mL. Two derivatives exhibited minimum inhibitory concentrations of 64 µg/mL against Klebsiella pneumoniae, while compound 28 demonstrated higher potency against MRSA than vancomycin.

Benefits in quality of life following an obstructive sleep apnea screening and treatment program in patients with acute ischemic stroke. / Beneficios en la calidad de vida de un programa de cribado y tratamiento de apnea obstructiva del sueño en pacientes con ictus isquémico agudo.

INTRODUCTION: Obstructive sleep apnea (OSA) has been proposed as a factor that worsens stroke prognosis. Our aim was to determine if an OSA intervention could improve quality of life (QOL, first objective) and modified Rankin score (mRS, second objective). PATIENTS AND METHODS: The intervention group of this quasi-experimental study included patients with acute ischemic stroke <72 hours who underwent polygraphy and Continuous Positive Airway Pressure (CPAP) and hygienic-dietary measures if required. The control group followed routine clinical practice. The Short Form 36 Health Survey (SF-36) and mRS were applied at the sixth month after stroke in both groups. RESULTS: Fifty-five vs. sixty-two patients were included in the intervention and control group respectively. In the intervention group, 64.71% of patients accepted the proposed CPAP (16 cases with a good adherence). An improvement in SF-36 items was detected in the intervention group: physical functioning (p = 0.008), role physical (p = 0.002), bodily pain (p = 0.008), general health (p <0.001), vitality (p = 0.001) and role emotional (p = 0.015). In a per-protocol analysis, all these improvements were verified in the group of patients treated with good CPAP adherence (p < 0.05 in all the same SF-36 items). The percentage of patients with physical component summatory = 50 was higher in the intervention group (p = 0.003). There were no differences in the median of mRS (p = 0.262). CONCLUSIONS: Although more evidence is needed, a significant improvement in QOL was suggested after our OSA intervention, particularly in patients with good CPAP adherence.

En el grupo de intervención, el 64,71% de los pacientes aceptó la CPAP indicada (16 casos con buena adhesión). Se detectó una mejoría en los ítems de la escala SF-36 en el grupo de intervención: funcionamiento físico (p = 0,008), rol físico (p = 0,002), dolor corporal (p = 0,008), salud general (p menor de 0,001), vitalidad (p = 0,001) y rol emocional (p = 0,015). En un análisis por protocolo, todas estas mejorías se comprobaron en el grupo de pacientes tratados con CPAP con buena adhesión (p menor de 0,05 en todos los ítems de la SF-36). El porcentaje de pacientes con el sumatorio del componente físico = 50 fue más alto en el grupo de intervención (p = 0,003). No había diferencias en la mediana de la mRS (p = 0,262). Conclusiones. Aunque se necesitan más evidencias, nuestro estudio sugiere una mejoría significativa de la calidad de vida tras nuestra intervención en la AOS, especialmente en pacientes con buena adhesión a la CPAP.

Intraventricular hemorrhage as complication after spinal surgery. Case report.

Remote intracranial hemorrhage (ICH) is a rare but dreaded complication after spinal surgery. The physiopathology of this phenomenon is closely related to a loss of cerebrospinal fluid (CSF) after an incidental durotomy during spine surgery. The most common remote ICH location is cerebellar, but few articles report intraventricular hemorrhage. Its clinic is associated with cerebral hypotension due to decreased CSF, mainly headache, dysarthria, hemiparesis, an impaired level of awareness and seizures. The diagnosis of remote ICH after a non-cranial surgery can be a challenge to anesthesiologists, this pathology should be suspected face an immediate neurological deterioration after anesthetic awakening. Non-specific symptoms make it difficult to identify the origin of intracranial hemorrhagic from other differential diagnoses. We present a patient with an impaired level of awareness and seizures who suffered a hemorrhage in the right ventricle with cerebral and cerebellar edema in the immediate postoperative period after spinal surgery.

Hemorragia intraventricular como complicación tras una cirugía espinal. Caso clínico / Intraventricular hemorrhage as complication after spinal surgery. Case report

La hemorragia intracraneal (HIC) remota es una rara pero temida complicación tras la cirugía espinal. La fisiopatología de este fenómeno se relaciona estrechamente con la pérdida de líquido cefalorraquídeo (LCR) tras una lesión dural incidental durante la cirugía espinal. La localización de la HIC remota más frecuente es la cerebelar, existiendo pocos casos publicados de hemorragia intraventricular. Su clínica está asociada a la hipotensión cerebral por disminución de LCR, destacando la cefalea, la disartria, la hemiparesia, el deterioro del nivel de conciencia y las convulsiones.El diagnóstico de una HIC remota tras una cirugía no craneal puede ser un reto para los anestesiólogos; esta enfermedad debería sospecharse ante un deterioro neurológico inmediato al despertar anestésico. La sintomatología inespecífica dificultará identificar el origen hemorrágico intracraneal frente a otros diagnósticos diferenciales.Exponemos el caso de un paciente con disminución del nivel de conciencia y convulsión que presentó una hemorragia intraventricular derecha con edema cerebral y cerebeloso en el postoperatorio inmediato de una cirugía espinal.(AU)

Bilateral serous retinal detachment in a patient with atypical presentation of preeclampsia due to HELLP syndrome.

Exudative retinal detachment (ERD) is a rare complication that occurring in 1% of patients with preeclampsia, its incidence is increased when it is associated with HELLP syndrome. Preeclampsia is defined by the development of arterial hypertension and proteinuira occurs after 20 weeks of gestation until postpartum. HELLP syndrome (low platelets, hemolysis and elevated liver enzymes) is a severe form of preeclampsia. ERD in preeclampsia is related to choroidal ischaemia, in the vast majority of the cases associated with hypertensive retinopathy. However, it has been proposed that the combination of hypertension with a microangiopathic hemolysis, hipercoagulability and hypoalbuminemia are the main factors contributing to the development of ERD. Its treatment includes a rapid resolution of labor to reverse ocular manifestations and prevent visual sequels. We describe the case of a pregnant woman with atypical preeclampsia who, in the postpartum of a cesarean, presented an ERD concomitantly with a HELLP syndrome.

Incidence of venous thromboembolic events in cancer patients receiving immunotherapy: a single-institution experience

Background Cancer and cancer therapies have been associated with an increased incidence of venous thromboembolic events (VTE). However, the incidence of VTE in patients on immunotherapy has not been well characterized. The aim of this study was to assess the incidence of VTE in cancer patients receiving immunotherapy and ascertain its prognostic utility. Materials and methods We conducted a single-institution retrospective study, including all cancer patients treated with anti-Programmed cell Death 1 (PD-1), anti-Programmed cell Death Ligand-1 (PD-L1), anti-Cytotoxic T-Lymphocyte-Associated Protein 4 (CTLA4), a combination of anti-PD-1/anti-PD-L1 and anti-CTLA4 or a combination including any of these drugs with chemotherapy, antiangiogenic agents or both between June 2013 and April 2019 at La Paz University Hospital, Madrid (Spain). Results We selected 229 patients. VTE occurred in 16 of 229 patients (7%). VTE occurred more frequently in patients with lung cancer followed by melanoma. Female sex and melanoma were independently associated with an increased risk of VTE. 12 of 16 VTE (75%) were symptomatic. Progressive disease to immunotherapy [HR 31.60 (95% CI 11.44–87.22), p = 0.00], lung cancer [HR 2.55 (95% CI 1.34–4.86), p = 0.00] and melanoma [HR 2.42 (1.20–4.86), p = 0.01] were independently associated with shorter OS. VTE occurrence was not independently associated with shorter OS [HR 1.33 (95% CI 0.63–2.80), p = 0.44]. Conclusions The incidence of VTE in cancer patients receiving immunotherapy in our study appeared to be similar to the incidence previously reported in other series of cancer patients treated with systemic therapies. VTE occurrence did not correlate with the prognosis. Further and prospective studies are needed to derive definitive conclusions (AU)

Estudio descriptivo de la esteatosis hepática y la morbilidad asociada en atención primaria. (Estudio ESTEATOAP) / Descriptive study of hepatic steatosis and associated morbidity in Primary Care. (ESTEATOAP Study)

OBJETIVO: Estudiar la prevalencia registrada de esteatosis hepática en atención primaria, así como la proporción de pacientes con diagnóstico de EHGNA que incluye el hígado graso simple no alcohólico (HGNA) y de esteatohepatitis no alcohólica frente a la esteatosis por otras causas. Además, se estudió la proporción de las morbilidades cardiometabólicas asociadas al HGNA. MATERIAL Y MÉTODOS: Estudio observacional descriptivo. La población de estudio es la de todos los pacientes con diagnóstico registrado de esteatosis hepática en un Centro de Salud urbano que atiende a una población de 25.747 mayores de 14 años. Se calculó un tamaño muestral de 229 pacientes. Se describen las características demográficas y clínicas asociadas. RESULTADOS: La prevalencia de esteatosis fue del 2,17%. Y de EHGNA del 1,51%. La media de edad de 62,42. Mujeres 114 mujeres (50,2%) y 113 varones (49,8%). Ciento cuarenta y siete (64,8%) fueron EHGNA y 64 (28,2%) fueron esteatosis por otras causas. La proporción de pacientes con EHGNA y transaminasas elevadas fue del 24,13% y la proporción de pacientes con EHGNA y elevación de GGT fue el 18,6%. Se ha encontrado una proporción elevada de EHGNA con factores de riesgo cardiometabólico: 93,9% de sobrepeso y obesidad, 55,1% de diabetes, 54,4% de hipertensión, 32,9% de síndrome metabólico, 35,2% hipertrigliceridemia y HDL de riesgo 19,6%. Entre los factores de riesgo cardiometabólicos y la EHGNA se encontró relación significativa en la diabetes, la obesidad y el síndrome metabólico. DISCUSIÓN: La prevalencia fue de solo el 1,51%, quizás por la escasa importancia que se da a esta enfermedad. Hay una proporción alta de EHGNA con factores de riesgo cardiometabólicos y más en la población general. Si se consideran todas las causas de esteatosis hay una asociación significativa entre obesidad, diabetes mellitus y síndrome metabólico con la EHGNA. CONCLUSIONES: La prevalencia registrada de EHGNA es muy inferior a la de los estudios poblacionales, además se ha encontrado una alta presencia de los factores cardiometabólicos en estos pacientes

OBJECTIVE: To study the recorded prevalence of hepatic steatosis in Primary Care, as well as the proportion of patients diagnosed with fatty liver diseases (FLD) including simple non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) versus steatosis by other causes. In addition, the proportion of cardiometabolic morbidities associated with NAFLD liver was studied. MATERIAL AND METHODS: A descriptive observational study was carried out on a population that included all patients with a recorded diagnosis of hepatic steatosis in an urban health centre that serves a population of 25,747 over the age of 14. A sample size of 229 patients was calculated. The demographic and clinical characteristics associated with hepatic steatosis are described. RESULTS: The prevalence of steatosis was 2.17% and 1.51% for NAFLD. The mean age was 62.42 years. The study included 114 (50.2%) women and 113 (49.8%) males. NAFLD was found in 147 (64.8%), and 64 (28.2%) were steatosis due to other causes. The proportion of patients with NAFLD and high transaminases was 24.13%, and the proportion of patients with NAFLD and GGT elevation was 18.6%. A high proportion of NAFLD had been found with cardiometabolic risk factors: 93.9% overweight and obesity, 55.1% diabetes, 54.4% hypertension, 32.9% metabolic syndrome, 35.2% hypertriglyceridaemia, and HDL risk 19.6%. A significant association was found between cardiometabolic risk factors and NAFLD in diabetes, obesity, and metabolic syndrome. DISCUSSION: Prevalence was only 1.51%, perhaps because of the low importance given to this disease. There is a high proportion of NAFLD with cardiometabolic risk factors and more in the general population. If all the causes of steatosis are considered there is a significant association between obesity, diabetes mellitus, and metabolic syndrome with NAFLD. CONCLUSIONS: The recorded prevalence of NAFLD is much lower than that of population studies, and a high presence of cardiometabolic factors has been found in these patients

Conjugation of NMR and SAXS for flexible and multidomain protein structure determination: From sample preparation to model refinement.

Experimental information from small angle X-ray scattering (SAXS) is conjugated with nuclear magnetic resonance (NMR) spectroscopy data for the improvement of protein structure determination, particularly for flexible, multidomain or intrinsically disordered proteins. Individually, each of these techniques presents capabilities and limitations: NMR excels in local information, providing atomic resolution, but is limited by protein size, whereas SAXS yields a global envelope of the protein with lower resolution, but revealing domain positions. Different conjugation methodologies use the complementarity of both techniques' independent constraints to achieve comprehensive protein structure determination and resolve dynamics at a moderate computational expense.
