Physiotherapy-Led Health Promotion Strategies for People with or at Risk of Cardiovascular Diseases: A Scoping Review.

Cardiovascular diseases (CVD) are prevalent and lead to high morbidity and mortality globally. Physiotherapists regularly interact with patients with or at risk of CVDs (pwCVDs). This study aimed to assess the nature of existing evidence, interventional approaches used, and the population groups included in physiotherapy-led health promotion (PLHP) for pwCVDs. The scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. Medline, PubMed, Web of Science, Cochrane Central Register of Controlled Trials, CINAHL, and PEDro databases were searched from inception until June 2023. Two reviewers independently screened the titles, abstracts, and full text and conducted data extraction. All conflicts were resolved with a third reviewer. A total of 4992 records were identified, of which 20 full-text articles were included in the review. The studies had varied populations, including those with stroke, coronary artery diseases, peripheral artery diseases, hypertension, diabetes, and multiple CVD risk factors. The interventions ranged from exercise and physical activity programmes, dietary interventions, education, and counselling sessions with various supplementary approaches. Most interventions were short-term, with less than 12 months of follow-up. Interventions were personalised and patient-centred to promote adherence and health behaviour change. Among the included studies, 60% employed experimental designs, with the remainder using quasi-experimental designs. Although a wide range of PLHP strategies have been used for pwCVDs, exercise and physical activity were employed in 85% of the included studies. Other components of health promotion, such as sleep, smoking, and alcohol abuse, should be investigated within PLHP.

Interventional Radiofrequency Treatment for the Sympathetic Nervous System: A Review Article.

INTRODUCTION: Interventional techniques such as radiofrequency (RF) treatment can be used to interrupt pain signals transmitted through the sympathetic nervous system (SNS). RF treatments including the pulsed (PRF) and continuous (CRF) modalities show enhanced control over lesion size and enhanced ability to confirm accurate positioning compared to other interventional methods. PRF also acts to reduce the area of the lesion. In this article, we characterize the currently available evidence supporting the use and efficacy of RF treatments in sympathetically mediated pain (SMP) conditions. STUDY DESIGN: A comprehensive literature review. METHODS: A PubMed and Cochrane Library database search was performed for human studies applying RF treatment at sympathetic sites (sphenopalatine ganglion, stellate ganglion, cervical, thoracic, or lumbar sympathetic ganglia, celiac plexus, splanchnic nerves, superior hypogastric plexus, and ganglion impar) between January 1970 to May 2020. Data were extracted, summarized into tables, and qualitatively analyzed. RESULTS: PRF and CRF both show promise in relieving SMP conditions, such as complex regional pain syndrome (CRPS), pain in the perineal region, headache and facial pain, and oncologic and non-oncologic abdominal pain, in addition to other types of pain, with minimal complications. Furthermore, in most comparative studies, outcomes using RF treatments exceeded other interventional techniques, such as anesthetic block and chemical neurolysis. CONCLUSIONS: RF treatments can be effective in carefully selected patients who are refractory to conservative management. However, further randomized controlled studies are needed prior to implementing it into common practice.

Encefalitis autoinmune en pediatría. Receptor antirreceptor N-metil D-aspartato (Anti-R-NMDA) / Autoimmune encephalitis in pediatrics. N-methyl D-aspartate Receptor Receiver (Anti-R-NMDA)

La encefalitis es un desorden inflamatorio del encéfa- lo que deriva en un estado mental alterado, crisis con- vulsivas, déficits neurológicos focales, acompañado usualmente de signos de inflamación en el líquido ce- falorraquídeo y hallazgos en la resonancia magnética que pueden ir desde normalidad hasta anormalidades extensas. El anticuerpo anti RNMDA es el que origi- na la mayoría de los casos de encefalitis autoinmune en niños y adultos jóvenes, seguido por el anticuerpo anti LGI1 de presentación en el adulto. Se caracteri- zan por estar frecuentemente asociadas a algún tumor, responder a la inmunoterapia y provocar daños cere- brales variables que se manifiestan como cuadros clí- nicos polimorfos (desde la disfunción límbica hasta una encefalopatía multifocal o difusa). La prevalencia exacta de las encefalitis autoinmunes es incierta, exis- tiendo un aumento importante del reporte de casos en los últimos 10 años, asociado al avance en la pesqui- sa de los anticuerpos contra un antígeno celular espe- cífico. Todas las encefalitis autoinmunes responden a terapia inmunomoduladora, generalmente la evolución a la mejoría es lenta y puede completarse en meses o incluso en un año o más. Revisaremos generalidades de la encefalitis autoinmune, su forma más común y discutiremos su enfoque diagnóstico y tratamiento...(AU)

Clevidipine as an antihypertensive drug in three pheochromocytoma surgeries: Case series / Clevidipino como fármaco antihipertensivo en tres cirugías de feocromocitoma: Serie de casos

Abstract Introduction Laparoscopic adrenalectomy is the treatment of choice of pheochromocytoma. During the first surgical phase (pneumoperitoneum insufflation, tumor and veins handling), there is a risk of hypertensive crisis due to catecholamine release. After tumor excision, patients can suffer relative vasodilation and the residual effect of antihypertensive drugs, which results in arterial hypotension. For that reason, antihypertensive drugs used in the first phase should have a rapid onset of action, short half-life and no residual effect. Methods We report a series of three cases of patients with pheochromocytoma who were treated with laparoscopic adrenalectomy. They all received clevidipine infusion from the beginning of the surgery, before they had presented hypertension, to treat and try to minimize hypertensive peaks. Results In all patients, hypertensive peaks were controlled in a few minutes. After tumor resection, clevidipine infusion was stopped in all cases, and any patient required infusion of vasopressors. Discussion Clevidipine could be a first choice antihypertensive drug in pheochromocytoma surgery. Starting the infusion of clevidipine before the hypertensive peaks could help to make them less pronounced.

Resumen Introducción La adrenalectomía laparoscópica es el tratamiento de elección del feocromocitoma. Durante la primera fase quirúrgica (insuflación de neumoperitoneo, manipulación del tumor y de las venas implicadas), existe el riesgo de que se desencadenen crisis hipertensivas debido a la liberación de catecolaminas. Después de la extirpación del tumor, los pacientes pueden sufrir una vasodilatación relativa y el efecto residual de los fármacos antihipertensivos usados previamente, lo que resulta en hipotensión arterial. Por esa razón, los fármacos antihipertensivos utilizados en la primera fase quirúrgica deben tener rápido inicio de acción, vida media corta y mínimo efecto residual. Métodos Se describe una serie de casos de tres pacientes con feocromocitoma que fueron tratados con adrenalectomía laparoscópica. Todos recibieron infusión de clevidipino desde el comienzo de la cirugía, antes de presentar hipertensión arterial, para así intentar minimizar y tratar rápidamente los posibles picos hipertensivos. Resultados En todos los pacientes los picos hipertensivos se controlaron en pocos minutos. Después de la resección del tumor, la infusión de clevidipino se detuvo en todos los casos y ningún paciente requirió perfusión de vasopresores. Discusión El clevidipino podría ser un fármaco antihipertensivo de primera elección en la cirugía de feocromocitoma. Iniciarlo antes de que ocurran los picos hipertensivos podría ayudar a que sean más leves.

Phenylpropanoids Are Connected to Cell Wall Fortification and Stress Tolerance in Avocado Somatic Embryogenesis.

Somatic embryogenesis (SE) is a valuable model for understanding the mechanism of plant embryogenesis and a tool for the mass production of plants. However, establishing SE in avocado has been complicated due to the very low efficiency of embryo induction and plant regeneration. To understand the molecular foundation of the SE induction and development in avocado, we compared embryogenic (EC) and non-embryogenic (NEC) cultures of two avocado varieties using proteomic and metabolomic approaches. Although Criollo and Hass EC exhibited similarities in the proteome and metabolome profile, in general, we observed a more active phenylpropanoid pathway in EC than NEC. This pathway is associated with the tolerance of stress responses, probably through the reinforcement of the cell wall and flavonoid production. We could corroborate that particular polyphenolics compounds, including p-coumaric acid and t-ferulic acid, stimulated the production of somatic embryos in avocado. Exogen phenolic compounds were associated with the modification of the content of endogenous polyphenolic and the induction of the production of the putative auxin-a, adenosine, cellulose and 1,26-hexacosanediol-diferulate. We suggest that in EC of avocado, there is an enhanced phenylpropanoid metabolism for the production of the building blocks of lignin and flavonoid compounds having a role in cell wall reinforcement for tolerating stress response.

Carcinoma de plexo coroideo en paciente pediátrico: reporte de caso / Choroid plexus carcinoma in pediatric pacient: case report

El carcinoma de plexo coroideo se considera dentro de los tumores del cerebro como uno de los más infrecuentes, presentándose principalmente en la población pediátrica con mayor incidencia en hombres. Las principales manifestaciones clínicas son secundarias a la obstrucción del flujo de líquido cefalorraquídeo. Dentro de los estudios de imagen que se pueden emplear para realizar el diagnóstico están la tomografía computarizada y la resonancia magnética sin embargo el diagnóstico definitivo es el estudio anatomopatológico. Presentamos el caso clínico de un niño de 13 años de edad que acudió a la emergencia de pediatría del Hospital Mario Catarino Rivas por cefalea de dos meses de evolución que posteriormente presentó alteración de la marcha y hemiparesia derecha. El principal objetivo de tratamiento es la resección total sin embargo no se logra en todos los casos. Se ha propuesto el uso de quimioterapia adyuvante con o sin radiación, sin embargo, aún no se ha estandarizado este enfoque...

Electron-Mediated Aminyl and Iminyl Radicals from C5 Azido-Modified Pyrimidine Nucleosides Augment Radiation Damage to Cancer Cells.

Two classes of azido-modified pyrimidine nucleosides were synthesized as potential radiosensitizers; one class is 5-azidomethyl-2'-deoxyuridine (AmdU) and cytidine (AmdC), while the second class is 5-(1-azidovinyl)-2'-deoxyuridine (AvdU) and cytidine (AvdC). The addition of radiation-produced electrons to C5-azido nucleosides leads to the formation of π-aminyl radicals followed by facile conversion to σ-iminyl radicals either via a bimolecular reaction involving intermediate α-azidoalkyl radicals in AmdU/AmdC or by tautomerization in AvdU/AvdC. AmdU demonstrates effective radiosensitization in EMT6 tumor cells.
