Effectiveness of ozone therapy to reduce pain in patients with temporomandibular disorders

Introducción: los trastornos temporomandibulares constituyen un problema de salud importante que afecta a más del 50% de la población mundial en algún momento de su vida. Objetivo: evaluar la efectividad de la ozonoterapia para disminuir el dolor en los pacientes con trastornos temporomandibulares. Método: se realizó un estudio cuasi-experimental prospectivo en enfermos con trastornos temporomandibulares pertenecientes a la Clínica Estomatológica “Mártires de Sagua” atendidos en la Sala de Rehabilitación del Policlínico Docente “Idalberto Revuelta” en 2016. La muestra estuvo constituida por 30 pacientes, la selección se realizó a través de un muestreo no probabilístico por criterios y quedó conformada por un grupo experimental de 10 enfermos en los que se añadió la ozonoterapia al tratamiento convencional y un grupo control de 20 pacientes con solo tratamiento convencional. En ambos grupos se solicitó el consentimiento informado para participar en la investigación según el tratamiento asignado y brindar datos acerca de su evolución. Resultados: predominaron las edades entre 50 y 59 años y el sexo femenino; antes del tratamiento predominó la intensidad del dolor moderada y los indicadores empleados para valorar la evolución clínica mostraron resultados porcentualmente superiores en el grupo experimental. Conclusiones: la modalidad de tratamiento que combina la terapia convencional con el ozono es más efectiva que la aplicación de la terapia convencional sola en los pacientes con trastornos temporomandibulares.Introduction: temporomandibular disorders are a major health problem that affects more than 50% of the world population at some point in their lives.

Targeted reprogramming of H3K27me3 resets epigenetic memory in plant paternal chromatin

Epigenetic marks are reprogrammed in the gametes to reset genomic potential in the next generation. In mammals, paternal chromatin is extensively reprogrammed through the global erasure of DNA methylation and the exchange of histones with protamines(1,2). Precisely how the paternal epigenome is reprogrammed in flowering plants has remained unclear since DNA is not demethylated and histones are retained in sperm(3,4). Here, we describe a multi-layered mechanism by which H3K27me3 is globally lost from histone-based sperm chromatin in Arabidopsis. This mechanism involves the silencing of H3K27me3 writers, activity of H3K27me3 erasers and deposition of a sperm-specific histone, H3.10 (ref. (5)), which we show is immune to lysine 27 methylation. The loss of H3K27me3 facilitates the transcription of genes essential for spermatogenesis and pre-configures sperm with a chromatin state that forecasts gene expression in the next generation. Thus, plants have evolved a specific mechanism to simultaneously differentiate male gametes and reprogram the paternal epigenome

Fish sperm motility assessment as a tool for aquaculture research, a historical approach

[EN] Fish sperm motility is nowadays considered the best biomarker for the quality of fish spermatozoa, and sperm motion parameters from more than 300 fish species have been reported in more than 1500 scientific articles covering a wide range of topics, from molecular biology to ecology. The most studied topics have been (i) the sperm storage (involving both the use of chilled¿storage protocols for short¿term periods and sperm cryopreservation techniques for long¿term storage), (ii) the sperm physiology (fathom in the spermatozoa activation process and the whole propulsion machinery of the sperm cells) and (iii) the broodstock management (covering aspects such as rearing conditions, dietary requirements or hormonal induction treatments). In addition, other aquaculture and ecological topics, such as (iv) the knowledge of the breeding cycle of the species, (v) the phenomenon of the sperm competition and (vi) ecotoxicological studies for the evaluation of aquatic environments, have also been approached from the evaluation of sperm motion performance. Therefore, fish sperm motility assessment can serve as a potential tool for aquaculture and ecological purposes, covering key topics of fundamental and applied research. This review gives an overview of the major research areas in which fish sperm motility has been applied successfully.This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement no. 642893 (IMPRESS).

Evaluation of an interpersonal skills program in gifted children

Algunos trabajos de investigación informan que cierto número de niños superdotados muestran problemas de adaptación social y habilidades sociales e interpersonales, mientras que otros consideran que esto no ocurre. Partiendo de lo anterior, Neihart, Reis, Robinson y Moon (2002) hablan de enfoque de resiliencia versus enfoque de riesgo. En este trabajo se considera el beneficio de aplicar programas de entrenamiento en habilidades interpersonales en niños superdotados para prevenir posibles problemas. Por ello, se pretende valorar la eficacia de un programa de entrenamiento en resolución de problemas interpersonales en esta población. En esta investigación participaron 40 niños superdotados de edades comprendidas entre 7 y 13 años, divididos en un grupo tratamiento y un grupo control de lista de espera. Los resultados mostraron diferencias significativas en las medidas de valoración directa en el grupo tratamiento tras la aplicación del programa. También se detectaron diferencias significativas entre el grupo tratamiento y el grupo control en las medidas postratamiento a favor del primero, y se confirmó la relación del potencial de aprendizaje de los niños con los beneficios obtenidos. En definitiva, el programa de entrenamiento se muestra eficaz en la mejora de las habilidades de solución de problemas interpersonales evaluadas en niños superdotados.Certain research studies report that a number of gifted children show social adaptation issues, as well as problems with social and interpersonal skills, while others consider that this does not occur. In this regard, Neihart, Reis, Robinson and Moon (2002) speaks of a resilience approach versus a risk approach. From the risk viewpoint, this paper presents the benefits of applying training programs in interpersonal skills as to prevent potential problems in gifted children. For this reason, we aim to evaluate the effectiveness of a training program for solving interpersonal problems in this population. Participants include 40 gifted children aged 7 to 13, divided into a treatment group and a control – waitlisted – group. Program application results show significant differences in direct assessment measurements in the treatment group. An increase in effect sizes between the treatment group and the control group is also detected, in favor of the former, and a relationship between the children's learning potential and the benefits obtained is also confirmed. In short, the training program proves effective in interpersonal problem-solving skill improvement in children with high intellectual capacity.Esta investigación fue financiada por el Ministerio de Economía y Competitividad de España, programa de Proyectos de investigación I+D convocatoria 2011, Ref. 2011-24370.Open Access funded by Fundación Universitaria Konrad Lorenz

A roadmap for island biology: 50 fundamental questions after 50 years of The Theory of Island Biogeography

Aims The 50th anniversary of the publication of the seminal book, The Theory of Island Biogeography, by Robert H. MacArthur and Edward O. Wilson, is a timely moment to review and identify key research foci that could advance island biology. Here, we take a collaborative horizon-scanning approach to identify 50 fundamental questions for the continued development of the field. Location Worldwide. Methods We adapted a well-established methodology of horizon scanning to identify priority research questions in island biology, and initiated it during the Island Biology 2016 conference held in the Azores. A multidisciplinary working group prepared an initial pool of 187 questions. A series of online surveys was then used to refine a list of the 50 top priority questions. The final shortlist was restricted to questions with a broad conceptual scope, and which should be answerable through achievable research approaches. Results Questions were structured around four broad and partially overlapping island topics, including: (Macro)Ecology and Biogeography, (Macro)Evolution, Community Ecology, and Conservation and Management. These topics were then subdivided according to the following subject areas: global diversity patterns (five questions in total); island ontogeny and past climate change (4); island rules and syndromes (3); island biogeography theory (4); immigration–speciation–extinction dynamics (5); speciation and diversification (4); dispersal and colonization (3); community assembly (6); biotic interactions (2); global change (5); conservation and management policies (5); and invasive alien species (4). Main conclusions Collectively, this cross-disciplinary set of topics covering the 50 fundamental questions has the potential to stimulate and guide future research in island biology. By covering fields ranging from biogeography, community ecology and evolution to global change, this horizon scan may help to foster the formation of interdisciplinary research networks, enhancing joint efforts to better understand the past, present and future of island biotas

Canagliflozin and renal outcomes in type 2 diabetes and nephropathy

BACKGROUND Type 2 diabetes mellitus is the leading cause of kidney failure worldwide, but few effective long-term treatments are available. In cardiovascular trials of inhibitors of sodium–glucose cotransporter 2 (SGLT2), exploratory results have suggested that such drugs may improve renal outcomes in patients with type 2 diabetes. METHODS In this double-blind, randomized trial, we assigned patients with type 2 diabetes and albuminuric chronic kidney disease to receive canagliflozin, an oral SGLT2 inhibitor, at a dose of 100 mg daily or placebo. All the patients had an estimated glomerular filtration rate (GFR) of 30 to <90 ml per minute per 1.73 m2 of body-surface area and albuminuria (ratio of albumin [mg] to creatinine [g], >300 to 5000) and were treated with renin–angiotensin system blockade. The primary outcome was a composite of end-stage kidney disease (dialysis, transplantation, or a sustained estimated GFR of <15 ml per minute per 1.73 m2), a doubling of the serum creatinine level, or death from renal or cardiovascular causes. Prespecified secondary outcomes were tested hierarchically. RESULTS The trial was stopped early after a planned interim analysis on the recommendation of the data and safety monitoring committee. At that time, 4401 patients had undergone randomization, with a median follow-up of 2.62 years. The relative risk of the primary outcome was 30% lower in the canagliflozin group than in the placebo group, with event rates of 43.2 and 61.2 per 1000 patient-years, respectively (hazard ratio, 0.70; 95% confidence interval [CI], 0.59 to 0.82; P=0.00001). The relative risk of the renal-specific composite of end-stage kidney disease, a doubling of the creatinine level, or death from renal causes was lower by 34% (hazard ratio, 0.66; 95% CI, 0.53 to 0.81; P<0.001), and the relative risk of end-stage kidney disease was lower by 32% (hazard ratio, 0.68; 95% CI, 0.54 to 0.86; P=0.002). The canagliflozin group also had a lower risk of cardiovascular death, myocardial infarction, or stroke (hazard ratio, 0.80; 95% CI, 0.67 to 0.95; P=0.01) and hospitalization for heart failure (hazard ratio, 0.61; 95% CI, 0.47 to 0.80; P<0.001). There were no significant differences in rates of amputation or fracture. CONCLUSIONS In patients with type 2 diabetes and kidney disease, the risk of kidney failure and cardiovascular events was lower in the canagliflozin group than in the placebo group at a median follow-up of 2.62 years

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Sperm DNA fragmentation: A new guideline for clinicians

Sperm DNA integrity is crucial for fertilization and development of healthy offspring. The spermatozoon undergoes extensive molecular remodeling of its nucleus during later phases of spermatogenesis, which imparts compaction and protects the genetic content. Testicular (defective maturation and abortive apoptosis) and post-testicular (oxidative stress) mechanisms are implicated in the etiology of sperm DNA fragmentation (SDF), which affects both natural and assisted reproduction. Several clinical and environmental factors are known to negatively impact sperm DNA integrity. An increasing number of reports emphasizes the direct relationship between sperm DNA damage and male infertility. Currently, several assays are available to assess sperm DNA damage, however, routine assessment of SDF in clinical practice is not recommended by professional organizations
