Efectividad de la intervención motora temprana en el desarrollo motor de los niños con parálisis cerebral entre 3 y 5 años de edad. Revisión sistemática / Effectiveness of early motor interventions in children with cerebral palsy between 3 to 5 years of age: Systematic review

La intervención motora temprana es esencial en niños con parálisis cerebral; sin embargo, se desconoce su efectividad entre los 3 y los 5años. El objetivo fue determinar la efectividad de la intervención motora temprana en el desarrollo motor de dicha población. Se realizó una revisión sistemática de literatura acerca de intervenciones motoras tempranas realizada en diferentes bases de datos como Pubmed/Medline, PEDro, OTSeeker, Embase y LILACS. Finalmente se seleccionaron 18 artículos, de los cuales 4 presentaron cambios a favor del grupo experimental en los desenlaces desarrollo motor global y función motora manual, con la terapia de integración sensorial y la terapia de movimiento inducido por restricción, respectivamente; no obstante, los resultados no fueron estadísticamente significativos y el nivel de evidencia fue bajo. La intervención motora temprana podría incluirse con precaución para la mejoría del desarrollo motor global y la función manual. Es necesario realizar estudios de mayor calidad metodológica. (AU)

Imaging of Endometriotic Lesions Using cRGD-MN Probe in a Mouse Model of Endometriosis.

Approximately 10% of women suffer from endometriosis during their reproductive years. This disease is a chronic debilitating condition whose etiology for lesion implantation and survival heavily relies on adhesion and angiogenic factors. Currently, there are no clinically approved agents for its detection. In this study, we evaluated cRGD-peptide-conjugated nanoparticles (RGD-Cy5.5-MN) to detect lesions using magnetic resonance imaging (MRI) in a mouse model of endometriosis. We utilized a luciferase-expressing murine suture model of endometriosis. Imaging was performed before and after 24 h following the intravenous injection of RGD-Cy5.5-MN or control nanoparticles (Cy5.5-MN). Next, we performed biodistribution of RGD-Cy5.5-MN and correlative fluorescence microscopy of lesions stained for CD34. Tissue iron content was determined using inductively coupled plasma optical emission spectrometry (ICP-OES). Our results demonstrated that targeting endometriotic lesions with RGD-Cy5.5-MN resulted in a significantly higher delta T2* upon its accumulation compared to Cy5.5-MN. ICP-OES showed significantly higher iron content in the lesions of the animals in the experimental group compared to the lesions of the animals in the control group. Histology showed colocalization of Cy5.5 signal from RGD-Cy5.5-MN with CD34 in the lesions pointing to the targeted nature of the probe. This work offers initial proof-of-concept for targeting angiogenesis in endometriosis which can be useful for potential clinical diagnostic and therapeutic approaches for treating this disease.

Results of the national registry of patients diagnosed with inflammatory bowel disease candidates for bariatric surgery (ReNacEIBar).

BACKGROUND: Our aim is to carry out a national registry of patients with inflammatory bowel disease (IBD) who underwent bariatric surgery, as well as evaluate the results and management of this type of patients in the usual clinical practice. METHODS: National multicentric observational retrospective study, including patients, previously diagnosed with IBD who underwent bariatric surgery from January 2000 to December 2022. RESULTS: Forty-one patients have been included: 43,9% previously diagnosed with ulcerative colitis, 57,3% Crohn's disease, and an indeterminate colitis (2,4%). The preoperative BMI was 45.8 ± 6,1 kg/m2. Among the bariatric surgeries, 31 (75,6%) sleeve gastrectomy, 1 (2,4%) gastric bypass and 9 (22%) one anastomosis gastric have been carried out. During the postoperative period, 9.8% complications have been recorded. BMI was 29,5 ± 4,7 kg/m2 and percent total weight lost was 33,9 ± 9,1% at 12 months. CONCLUSIONS: Bariatric surgery in patients with inflammatory bowel disease can be considered safe and effective.

Bile reflux after bariatric surgery.

The growing epidemic of obesity and the increase in weight loss surgery has led to a resurgence of interest in biliary reflux because anatomical alterations may be refluxogenic. HIDA scan is the least invasive scan with good patient tolerability, sensitivity and reproducibility for the diagnosis of biliary reflux. Patients with more advanced oesophageal lesions have a higher degree of duodenal reflux. It has been shown in animal models and in vitro that there is more Barrett's and dysplasia with duodenal reflux. There are two cases of post-OAGB malignancy reported in 20 years, both without correlation with a biliary aetiology, so the carcinogenic risk probably remains theoretical. Prospective trials on OAGB should include endoscopy preoperatively and at 5-year intervals, to have data on the real effects of bile exposure on the gastric reservoir and oesophagus.

Stand-alone optical spinning tweezers with tunable rotation frequency.

Advances in optical trapping design principles have led to tremendous progress in manipulating nanoparticles (NPs) with diverse functionalities in different environments using bulky systems. However, efficient control and manipulation of NPs in harsh environments require a careful design of contactless optical tweezers. Here, we propose a simple design of a fibered optical probe allowing the trapping of dielectric NP as well as a transfer of the angular momentum of light to the NP inducing its mechanical rotation. A polarization conversion from linearly-polarized incident guided to circularly transmitted beam is provoked geometrically by breaking the cylindrical symmetry of a coaxial nano-aperture that is engraved at the apex of a tapered metal coated optical fiber. Numerical simulations show that this simple geometry tip allows powerful light transmission together with efficient polarization conversion. This guarantees very stable trapping of quasi spherical NPs in a non-contact regime as well as potentially very tunable and reversible rotation frequencies in both directions (up to 45 Hz in water and 5.3 MHz in air for 10 mW injected power in the fiber). This type of fiber probe opens the way to a new generation of miniaturized tools for total manipulation (trapping, sorting, spinning) of NPs.

The synthetic molecule stauprimide impairs cell growth and migration in triple-negative breast cancer.

Stauprimide, a semi-synthetic derivative of staurosporine, is known mainly for its potent differentiation-enhancing properties in embryonic stem cells. Here, we studied the effects of stauprimide in cell growth and migration of triple-negative breast cancer cells in vitro, evaluating its potential antitumoral activity in an orthotopic mouse model of breast cancer in vivo. Our results from survival curves, EdU incorporation, cell cycle analysis and annexin-V detection in MDA-MB-231 cells indicated that stauprimide inhibited cell proliferation, arresting cell cycle in G2/M without induction of apoptosis. A decrease in the migratory capability of MDA-MB-231 was also assessed in response to stauprimide. In this work we pointed to a mechanism of action of stauprimide involving the modulation of ERK1/2, Akt and p38 MAPK signalling pathways, and the downregulation of MYC in MDA-MB-231 cells. In addition, orthotopic MDA-MB-231 xenograft and 4T1 syngeneic models suggested an effect of stauprimide in vivo, increasing the necrotic core of tumors and reducing metastasis in lung and liver of mice. Together, our results point to the promising role of stauprimide as a putative therapeutic agent in triple-negative breast cancer.

Effects of ascorbic acid addition on the oxidative stress response of Oryza sativa L. plants to As(V) exposure.

Accumulation of noxious elements in the edible part of crops and its impact on food safety is of increasing concern. Rice is one of the major staple food crops worldwide, including arsenic (As)-polluted areas, in which dietary As exposure is becoming a widespread health threat. Plant chemical priming has been shown to be an effective strategy to enhance tolerance to environmental stresses, including metal(loid) exposure. The priming effect of ascorbic acid (AsA) was assessed in rice seedlings exposed to As(V) in a hydroponics experiment. AsA treatment (co-addition to the growing media concomitantly (t0) or 24 h in advance (t24)) prevented an excessive accumulation of As in the roots (that decreased âˆ¼ 60%) and stimulated the activities of photosynthetic and antioxidant attributes (∼1.2-fold) in the aerial part of the plants. The increase in proline levels in both shoots (∼2.1-fold) and roots (∼2.4-fold) was found to be the most sensitive stress parameter, and was able to reflect the AsA-induced reduction of As toxic effects (concentrations back to Control levels, both simultaneously added or added as a pretreatment) in the aerial part of the plants. However, the phytotoxic effects related to As exposure were not fully prevented by priming with AsA, and further research is needed to find alternative priming approaches.

Response of Phragmites australis to increasing As(V) concentrations: Accumulation and speciation of As, and plant oxidative stress.

The use of macrophytes has been proposed recently as a suitable option for the phytostabilization or rhizofiltration of soils or waters contaminated by trace elements. As one of the most representative species of this type of plant, common reed (Phragmites australis (Cav.) Trin. ex Steud.) has shown tolerance to high concentrations of potentially hazardous elements, as is the case of arsenic. However, a deeper knowledge of how these plants deal with this toxicity, including their oxidative response, is needed for the optimum utilization of this species in phytoremediation procedures. In fact, little is known about how common reed plants react to As toxicity or the tolerance limits and accumulation potential of this species. In this work, common reed plants were exposed to a range of As(V) mass concentrations (0.5-10 mg L-1) in a hydroponic experiment, and the performance of the plants (growth, photosynthetic pigments, and oxidative stress related parameters) was evaluated and related to the major As species present in the different parts of the plants. The plants did not show any apparent symptom of toxicity and no significant effects were found for any of the different plant parameters analyzed. Arsenic was mostly accumulated as As(III) in the roots of the plants, and almost no translocation to the aerial part of the plants was observed for any of the As species analyzed. Common reed has shown a high capacity for As accumulation in its roots with no signs of toxicity, despite small nutrient imbalances. Thus, it can be considered to be a good candidate for use in the rhizofiltration and phytostabilization of As contaminated waters and soils, respectively.

Oral microbiome and systemic antineoplastics in cancer treatment: A systematic review.

BACKGROUND: Oral mucositis is one of the most common side effects in cancer patients receiving systemic antineoplastics. However, the underlying biological mechanisms leading to this condition are still unclear. For this reason, it has been hypothesised that systemic antineoplastics may cause an imbalance on the oral microbiota that subsequently triggers oral mucosa damage. MATERIAL AND METHODS: A systematic review was performed following the PRISMA protocol and the PICO question established was: patients diagnosed with cancer, who are candidates for receiving systemic antineoplastics (P=Patients), that undergo oral microbiome determinations (I=Intervention), before and after systemic antineoplastics administration (C=Comparison), to analyse changes in the oral microbiome composition (O=Outcome). The bibliographic search was carried out in PubMed and other scientific repositories. RESULTS: Out of 166 obtained articles, only 5 met eligibility criteria. Acute myeloid leukaemia (AML) was the most frequent type of cancer (40 %) among the participants. Only one of the studies included a control group of healthy subjects. Heterogeneity in the protocols and approaches of the included studies hindered a detailed comparison of the outcomes. However, it was stated that a decrease in bacteria α diversity is often associated with oral mucositis. On the other hand, fungal diversity was not associated with oral mucositis although α diversity was lower at baseline on patients developing oral candidiasis. CONCLUSIONS: There is insufficient scientific evidence of oral microbiological changes in patients undergoing systemic antineoplastics. Further investigations ought to be carried out to identify microorganisms that might play a key role in the pathogenesis of oral mucosa damage in patients undergoing systemic antineoplastics.

[What risk factors are associated with mortality and readmissions in osteoporotic hip fracture?] / ¿Qué factores de riesgo se asocian con la mortalidad y los reingresos en la fractura de cadera osteoporótica?

INTRODUCTION AND OBJECTIVE: Hip fracture in the elderly leads to long hospital stays, readmissions and mortality. OBJECTIVE: To identify risk factors associated with mortality and readmissions in elderly with hip fracture. PATIENTS AND METHODS: Prospective observational study in people over 65years with hip fracture between October-2017 and November-2018, followed for 12months (128 patients). STATISTICAL ANALYSIS: SPSS vs27.0. RESULTS: 6 (4.7%) patients were readmitted at 1 month; at year 24 (19.4%); 55 (44.4%) consulted for emergencies; 4 (3.1%) died during admission, and 26 (20.3%) in 12months; hospital stay 6.5 (SD: 4.80) days. Those with a previous Barthel less than 85 (6 [8.5%] vs 0 [0%]; P=.037) and less EuroQol5D (6 [10.0] vs 0 [0%]; P=.011) were readmitted more at one month. Those taking anticoagulants (OR: 3.33 (1.13-9.81); P=.003) and those with high surgical risk (18 [23.4%] vs 1 [5.6%]) were readmitted more after one year; P=.038). There was higher intra-episode mortality with renal failure (OR: 34.2 [3.25-359.93]; P=.003) and decompensated heart failure (OR: 23.8 [2.76-205.25]; P=.015). Higher mortality at one year in those older than 85years (OR: 4.3 [1.48-12.49]; P=.007); in those taking benzodiazepines (OR: 2.86 [1.06-7.73]; P=.038); if Barthel was less than 85 (OR: 2.96 [1.1-7.99]; P=.027) and if EuroQol5D was low (0.249 vs 0.547; P=.025). Those operated after 72h (24 [57.1%] vs. 29 [38.2%]; P=.047) consulted more for the emergency department. CONCLUSIONS: Renal failure and cardiac decompensation increased intra-episode mortality. Older age, benzodiazepines, and previous low functionality and low EuroQol5D increased mortality at one year. They were readmitted more if higher surgical risk, previously anticoagulated and worse quality of life and functionality.

Differential response of Oryza sativa L. and Phragmites australis L. plants in trace elements contaminated soils under flooded and unflooded conditions.

Drastic changes in the water regime of trace elements (TEs) contaminated soils under semiarid conditions, from completely dry to flooding situations, may alter the solubility of the contaminants and, therefore, their potential mobility and availability to plants. Certain macrophyte species have shown a promising suitability for their use in the phytoremediation of TEs contaminated soils under fluctuating flooded-unflooded conditions, as a consequence of their high resistance and tolerance to contamination. Similarly, different water conditions occur during rice (Oryza sativa) cultivation, a species often used as a model plant for TEs toxicity studies. The aim of this work was to study the tolerance and oxidative response to TEs of common reed (Phragmites australis) and rice grown in contaminated mining soils, when exposed to different water saturation conditions. Both species (common reed and rice) were cultivated in three different contaminated soils from the Sierra Minera of La Unión-Cartagena (SE-Spain) under contrasting water saturation conditions (flooded and unflooded) in a pot experiment. Soil EC and elevated metal (mainly Cd and Zn) soluble concentrations conditioned the survival of the plants. Whereas, As accumulation in the aerial part of both species influenced the most oxidative stress homeostasis. Common reed showed to be a good candidate for its use in the phytostabilization of TEs contaminated soils under both flooded and unflooded conditions.

Severity and duration of allergic conjunctivitis: are they associated with severity and duration of allergic rhinitis and asthma?

Summary: Objective. The association of allergic conjunctivitis (AC) with rhinitis and/or asthma is poorly understood. The objective of this study was to apply the Consensus Document for Allergic Conjunctivitis (DECA) criteria for the classification of AC to a population of patients with AC to assess the association between the severity and duration of AC and rhinitis and/or asthma. Methods. Patients with ocular symptoms of AC who participated in the 'Alergológica 2015' study were included. The demographics, classification according to the DECA criteria, etiology, and comorbidities were evaluated by age groups (less or equal than 14 and greater than 14 years). Results. A total of 2,914 patients (age range, 1-90 years) were included in the "Alergológica 2015" study. Of these, 965 patients (33.1%) were diagnosed with AC (77.5% > 14 years). AC was classified as severe, moderate, or mild in 1.8%, 46.4%, and 51.8%, respectively; and as intermittent or persistent in 51.6% and 48.4% of the patients. AC alone occurred in 4% of patients. AC was mainly associated with rhinitis (88.4%), asthma (38.2%), food allergy (8.3%) and atopic dermatitis (3.5%). In allergic respiratory disease rhinitis preceded AC and asthma developed later. The severity and duration of AC was significantly associated with severity and duration of rhinitis (p less than 0.001 for both age groups) and asthma (p less than 0.001 only in adults). Conclusions. The application of the new DECA classification for AC reveals a direct relationship between AC, rhinitis and asthma respect to severity and duration. These relationships suggest that AC should be considered an integral part of the "one airway, one disease" hypothesis.

Using self-etch adhesive agents with pit and fissure sealants. In vitro analysis of shear bond strength, adhesive remnant index and enamel etching patterns.

PURPOSE: The aim of this study was to evaluate in vitro, the shear bond strength (SBS) and adhesive remnant index (ARI) of pit and fissure sealants (PFS) after enamel conditioning with different new-generation self-etching (SE) agents; additionally, enamel etching patterns were assessed. METHODS: Healthy unerupted third molars surgically removed for therapeutic reasons (n = 25p/g), were randomly assigned to six groups. Conventional etching (CE) or SE was applied prior to pit and fissure sealants bonding. Enamel conditioned surfaces were evaluated by SEM at × 500, × 1000, and × 2000 magnification to determine etching patterns. Subsequently, 25 PFS blocks (3 × 2 × 1.5 mm) p/g were bonded to enamel surface. Samples were stored in water at 37 °C for 24 h, previous to SBS and ARI test. One-way ANOVA and Tamhane statistic tests were used for SBS; while Mann-Whitney U and Kruskal-Wallis were employed for ARI (p ≤ 0.05). RESULTS: For SBS test, CE_PFS_3M and SE1_PFS_Shofu groups showed the lowest values (8.74 ± 4.02 and 8.75 ± 3.90, respectively). The highest scores were observed in SE_PFS_Kuraray group (13.46 ± 5.83). Significant differences in SBS and ARI assessments were found. All experimental groups showed type 1 etching pattern. CONCLUSION: The etching pattern was less pronounced in self-etching groups, which showed an equal or superior in vitro performance compared to conventional etching agents. The clinical use of self-etching agents could be recommended before pit and fissure sealants application in new dental protocols. The best in vitro performance was observed when both applied materials, self-etching agent and pit and fissure sealant have 10-methacryloyloxydecyl dihydrogen phosphate in their chemical composition.
