Apolipoprotein E genotypes and amyloid burden associated with cognitive decline in non-demented Parkinson's disease patients: A preliminary analysis.

Background: Cognitive impairment is a common non-motor manifestation in Parkinson's disease (PD). Amyloidosis seems to accelerate the onset of dementia in PD. The Apolipoprotein (APOE) ε4 genotype is linked to amyloid aggregation and has been suggested to be a candidate for development of PD dementia, while other APOE alleles have been less investigated.

Use of the MNCD Classification to Monitor Clinical Stage and Response to Levodopa-Entacapone-Carbidopa Intestinal Gel Infusion in Advanced Parkinson's Disease.

Background And Objective: Staging Parkinson's disease (PD) with a novel simple classification called MNCD, based on four axes (Motor; Non-motor; Cognition; Dependency) and five stages, correlated with disease severity, patients' quality of life and caregivers' strain and burden. Our aim was to apply the MNCD classification in advanced PD patients treated with device-aided therapy (DAT).

Patients And Methods: A multicenter observational retrospective study of the first patients to start the levodopa-entacapone-carbidopa intestinal gel (LECIG) in Spain was performed (LECIPARK study).

Effectiveness and safety of levodopa-entacapone-carbidopa infusion in Parkinson disease: A real-world data study.

Background And Purpose: Levodopa-entacapone-carbidopa intestinal gel (LECIG) infusion is a recently developed device-aided therapy for advanced Parkinson disease (PD) patients. The aim of this study was to report real-world evidence about the effectiveness, tolerability, and safety of LECIG in PD patients.

Methods: A multicenter observational retrospective study of the first patients who initiated LECIG in Spain was performed.

Social Cognition in Parkinson's Disease after Focused Ultrasound Subthalamotomy: A Controlled Study.

Social cognition (SC) encompasses a set of cognitive functions that enable individuals to understand and respond appropriately to social interactions. Although focused ultrasound subthalamotomy (FUS-STN) effectively treats Parkinson's disease (PD) clinical motor features, its impact and safety on cognitive-behavioral interactions/interpersonal awareness are unknown. This study investigated the effects of unilateral FUS-STN on facial emotion recognition (FER) and affective and cognitive theory of mind (ToM) in PD patients from a randomized sham-controlled trial (NCT03454425).

Nigrostriatal blood-brain barrier opening in Parkinson's disease.

Background: The nigrostriatal system is especially vulnerable to neurodegeneration in Parkinson's disease (PD) and the blood-brain barrier (BBB) is a limiting factor for delivery of therapeutic agents to the brain. This pilot study aimed to demonstrate safety, feasibility and tissue penetration (by 18F-Choline-positron emission tomography (PET)) of MR-guided focused ultrasound (MRgFUS) simultaneous BBB opening (BBB-O) in the substantia nigra (SN) and putamen in PD.

Methods: Three patients underwent MRgFUS for midbrain and putamen BBB-O.

Social Cognition and Mild Cognitive Impairment in Mid-Stage Parkinson's Disease.

Mild cognitive impairment (MCI) is a relevant non-motor feature in Parkinson's disease (PD). Social cognition (SC) is a cognitive domain that refers to the ability to decode others' intentions and to guide behavior in social contexts. We aimed to compare SC performance in mid-stage PD patients compared to a healthy population and according to their cognitive state.

Cognitive Reserve in Parkinson's Disease without Dementia: β-Amyloid and Metabolic Assessment.

Background: Cognitive reserve (CR) is the mismatch between preserved cognition and neuropathological damage. Amyloidopathy in Parkinson's disease (PD) could be associated with faster progression to dementia, but the putative protective effect of CR is unknown.

Objectives: To evaluate the effect of CR on β-amyloid burden and brain metabolism in non-demented PD subjects.

Brain hypometabolism in non-demented microtubule-associated protein tau H1 carriers with Parkinson's disease.

Background And Purpose: The microtubule-associated protein tau (MAPT) H1 homozygosity (H1/H1 haplotype) is a genetic risk factor for neurodegenerative diseases, such as Parkinson's disease (PD). MAPT H1 homozygosity has been associated with conversion to PD; however, results are conflicting since some studies did not find a strong influence. Cortical hypometabolism is associated with cognitive impairment in PD.

Striatal Blood-Brain Barrier Opening in Parkinson's Disease Dementia: A Pilot Exploratory Study.

Background: Parkinson's disease (PD) exhibits a high prevalence of dementia as disease severity and duration progress. Focused ultrasound (FUS) has been applied for transient blood-brain barrier (BBB) opening of cortical regions in neurodegenerative disorders. The striatum is a primary target for delivery of putative therapeutic agents in PD.

Smoking influence on early and late fetal growth.

Objectives: Smoking during pregnancy is a leading and modifiable risk factor for fetal growth restriction (FGR) and low birthweight (<10th centile). We studied the effects of smoking in the development of early and late FGR or low birthweight, as well as in uteroplacental and fetoplacental hemodynamics of growth-restricted fetuses.

Methods: Retrospective cohort study of 5,537 consecutive singleton pregnancies delivered at ≤34 + 0 ("early delivery" group, n=95) and >34 + 0 ("late delivery" group, n=5,442) weeks of gestation.

What Do We Know about Theory of Mind Impairment in Parkinson's Disease?

Theory of mind (ToM) is a social cognitive skill that involves the ability to attribute mental states to self and others (what they think (cognitive ToM) and feel (affective ToM)). We aim to provide an overview of previous knowledge of ToM in Parkinson's disease (PD). In the last few years more attention has been paid to the study of this construct as a non-motor manifestation of PD.

Blood-brain barrier opening with focused ultrasound in Parkinson's disease dementia.

MR-guided focused ultrasound (MRgFUS), in combination with intravenous microbubble administration, has been applied for focal temporary BBB opening in patients with neurodegenerative disorders and brain tumors. MRgFUS could become a therapeutic tool for drug delivery of putative neurorestorative therapies. Treatment for Parkinson's disease with dementia (PDD) is an important unmet need.

Randomized Trial of Focused Ultrasound Subthalamotomy for Parkinson's Disease.

Background: The subthalamic nucleus is the preferred neurosurgical target for deep-brain stimulation to treat cardinal motor features of Parkinson's disease. Focused ultrasound is an imaging-guided method for creating therapeutic lesions in deep-brain structures, including the subthalamic nucleus.

Methods: We randomly assigned, in a 2:1 ratio, patients with markedly asymmetric Parkinson's disease who had motor signs not fully controlled by medication or who were ineligible for deep-brain stimulation surgery to undergo focused ultrasound subthalamotomy on the side opposite their main motor signs or a sham procedure.

Cortical disinhibition in Parkinson's disease.

In Parkinson's disease, striatal dopamine depletion produces profound alterations in the neural activity of the cortico-basal ganglia motor loop, leading to dysfunctional motor output and parkinsonism. A key regulator of motor output is the balance between excitation and inhibition in the primary motor cortex, which can be assessed in humans with transcranial magnetic stimulation techniques. Despite decades of research, the functional state of cortical inhibition in Parkinson's disease remains uncertain.

Obstetric and pediatric growth charts for the detection of late-onset fetal growth restriction and neonatal adverse outcomes.

Objectives: Late-onset fetal growth restriction (FGR) has heterogeneous prenatal and postnatal diagnostic criteria. We compared the prenatal and postnatal diagnosis of late-onset FGR and their ability to predict adverse perinatal outcomes.

Methods: Retrospective cohort study of 5442 consecutive singleton pregnancies that delivered beyond 34 + 0 weeks.

Focused ultrasound thalamotomy for multiple sclerosis-associated tremor.

Multiple sclerosis (MS)-related tremor is frequent and can often be refractory to medical treatment, which makes it a potential source of major disability. Functional neurosurgery approaches such as thalamic deep brain stimulation (DBS) or radiofrequency thalamotomy are proven to be effective, but the application of invasive techniques in MS tremor has so far been limited. Magnetic resonance (MR)-guided focused ultrasound thalamotomy, which has already been approved for treating essential and parkinsonian tremor, provides a minimally invasive approach that could be useful in the management of MS tremor.

Obstetric and pediatric growth charts for the detection of fetal growth restriction and neonatal adverse outcomes in preterm newborns before 34 weeks of gestation.

Introduction: Identification of fetal growth-restricted (FGR) infants depends on the fetal or newborn charts used to identify them. We aimed to compare the prenatal and postnatal diagnosis of FGR and their ability to predict adverse perinatal outcomes.

Methods: Observational retrospective cohort study of 95 consecutive mother-infant pairs with preterm birth between 24 and 34 weeks (study period: January 2014 to December 2015).

Breast cancer subtype discrimination using standardized 4-IHC and digital image analysis.

Breast cancer is a heterogeneous disease. Surrogate classification of intrinsic subtypes of invasive carcinomas by combined immunohistochemistry for estrogen receptor (ER), progesterone receptor (PR), HER2, and Ki67 (4-IHC) has increased steadily since the 2011 St Gallen symposium, due to its rapid subtyping of tumors at a reasonable cost. An important step in improving 4-IHC reproducibility and reliability will be to provide reference values from the routine use of standardized 4-IHC followed by image analysis.

Evaluation of a follow up protocol of infants born to mothers with antithyroid antibodies during pregnancy.

Aim: To evaluate the usefulness of a follow up intervention of newborns to mothers with antithyroid antibodies during pregnancy.

Results: We evaluated a 72 mother-infant pairs. Two to three blood tests were done at least in 50% of the infants included in the study during the follow up.

Oral care in a neonatal intensive care unit.

Objective: Compare the oral colonization profile of premature infants admitted at NICU before and after doing oral care routine with sterile water versus no intervention.

Methods: It was a randomized clinical trial composed of 37 premature infants admitted at the Neonatal Intensive Care Unit (NICU) with a birth weight (BW) <1500 g. They were distributed in two groups: the study group (SG) with 15 patients who received an oral hygiene with sterile water; and a control group (CG) (no intervention) formed by 22 patients.

Streptococcus pneumoniae: the forgotten microorganism in neonatal sepsis.

Unlabelled: Streptococcus pneumoniae is a rarely cause of neonatal sepsis. Its prevalence is low but with a mortality of 50%. Measures to prevent Streptococcus agalactiae transmission could help to increase Invasive Pneumococcal Disease (IPD) in newborns.

Dual-colour CISH is a reliable alternative to FISH for assessment of topoisomerase 2-alpha amplification in breast carcinomas.

Anthracyclines are among the most powerful antineoplastic drugs available for breast cancer treatment. Although HER2 amplification has been postulated to predict anthracycline benefit, numerous reports have demonstrated that HER2/TOP2A co-amplification is the clinically useful predictive marker of response to anthracyclines. The standard technique to evaluate gene status for target therapy selection is fluorescence in situ hybridization (FISH), but this technique has some disadvantages.

Family history and breast cancer hormone receptor status in a Spanish cohort.

Background: Breast cancer is a heterogenous disease that impacts racial/ethnic groups differently. Differences in genetic composition, lifestyles, reproductive factors, or environmental exposures may contribute to the differential presentation of breast cancer among Hispanic women.

Materials And Methods: A population-based study was conducted in the city of Santiago de Compostela, Spain.
