Proprioception in ankle sprain from exercises and bandages

Ankle sprains are the most common injuries in sports, usually causing damage to the lateral ligaments. Recurrence has as usual result permanent instability, and thus loss of proprioception. This fact, together with residual symptoms, is what is known as chronic ankle instability, CAI, or FAI, if it is functional. This problem tries to be solved by improving musculoskeletal stability and proprioception by the application of bandages and performing exercises. The aim of this study has been to review articles (meta-analisis, systematic reviews and revisions) published in 2009-2015 in PubMed, Medline, ENFISPO and BUCea, using keywords such as “sprain instability”, “sprain proprioception”, “chronic ankle instability”. Evidence affirms that there does exist decreased proprioception in patients who suffer from CAI. Rehabilitation exercise regimen is indicated as a treatment because it generates a subjective improvement reported by the patient, and the application of bandages works like a sprain prevention method limiting the range of motion, reducing joint instability and increasing confidence during exercise. As podiatrists we should recommend proprioception exercises to all athletes in a preventive way, and those with CAI or FAI, as a rehabilitation programme, together with the application of bandages. However, further studies should be generated focusing on ways of improving proprioception, and on the exercise patterns that provide the maximum benefit.

Sadun ymmärtämisen taitojen tukeminen, Seitsemän minuuttia sadulle -toimintamalli

Tutkimuksen tarkoituksena oli selvittää missä määrin varhaiskasvattajien saturyhmien ohjaamistyyli muuttuu lukuvuoden kestäneen satuprojektin aikana. Ohjaamistyylillä tarkoitettiin, lisääntyykö keskusteleva lukemistyyli ja ryhmän lasten osallistuminen sekä muuttuuko sadun ymmärtämisen tukeminen syksystä 2014 kevääseen 2015. Lisäksi analysoitiin monimetodisesti yhden varhaiskasvattajan ohjaamistyylin kehittymistä lukuvuoden aikana. Tutkimusaineisto perustuu yhden kaupungin päiväkoteihin, joissa syksyllä 2014 aloitettiin Seitsemän minuuttia sadulle -toimintamallin kokeilu viisivuotiaiden lasten pienryhmissä. Tutkimusaineiston muodosti kolme kertaa lukuvuoden aikana toteutetut saturyhmien videoinnit sekä kolme kertaa lukuvuoden aikana kerätyt varhaiskasvattajien satukyselyt. Saturyhmien videot analysoitiin yksityiskohtaisen arviointiluokittelun avulla, mikä johdettiin CLASS-menetelmän (Classroom Assesment Scoring System; Pianta, La Paro & Hamre [2008]) pohjalta sopimaan satuhetkien arviointiin. Videoiden analysoinnissa käytettiin lisäksi rinnakkaisarviointia, jossa tutkija ja satuprojektin johtaja analysoivat videot tahoillaan toisistaan riippumatta. Satukyselyistä valittiin tähän tutkimukseen yhden varhaiskasvattajan vastaukset, joista tarkasteltiin hänen kokemuksiaan saturyhmän ohjaamisesta. Tulokset osoittivat, että sadun ymmärtämisen tukeminen lisääntyi lukuvuoden aikana. Tutkimuksen yhtenä päätuloksena voidaan pitää sitä, että keskusteleva sadun lukeminen lisääntyi satuprojektin aikana. Saturyhmien lasten osallistuminen lisääntyi syyskuusta 2014 joulukuuhun 2014 ja pysyi keskimäärin samalla tasolla keväällä 2015. Tapauskyselyyn valitun varhaiskasvattajan sadun ymmärtämisen tukeminen lisääntyi lukuvuoden aikana. Saturyhmän lasten osallistuminen muuttui keskimääräisestä korkeaksi lukuvuoden aikana. Jokaisella kyselykerralla varhaiskasvattaja koki onnistuneensa jonkin verran (=3) tukemaan lasten sadun ymmärtämistä, asteikolla 1–5. Varhaiskasvattajan mukaan keskustelu ohjaamissaan satuhetkissä oli yleisempää keväällä 2015 kuin syksyllä 2014. Aiemmat tutkimukset ovat osoittaneet lasten sadun ymmärtämisen tukemisen merkityksen tulevan luetun ymmärtämisen kannalta. Emotionaalinen ja kognitiivinen tuki satuhetkissä voidaan nähdä ideaalitilanteena sadun ymmärtämisen näkökulmasta. Kasvattajan on tärkeää keskustella lapsen kanssa satuun liittyvistä vaikeista asioista ja ohjata lasta löytämään sadun tarjoamat kasvatukselliset näkökulmat, eli sadun tärkeimmät asiat. Lisäksi tärkeää on, että opettaja huomaa lapsen tarpeet ja tulkinnat satuhetkissä ja näin lapsi voi aktiivisesti osallistua yhteiseen toimintaan.

Influência da escala de cores na avaliação qualitativa das imagens de cintigrafia de perfusão do miocárdio

Introdução – A cintigrafia de perfusão do miocárdio (CPM) é utilizada no diagnóstico e seguimento de pacientes com doença arterial coronária, sendo a sua avaliação frequentemente realizada através da análise visual dos cortes tomográficos. A escala de cores selecionada é essencial na interpretação clínica das imagens de perfusão do miocárdio. Objetivo – Avaliar a influência de diferentes escalas de cores na avaliação qualitativa das imagens de CPM e estudar quais as mais adequadas para análise visual. Métodos – Trinta e cinco estudos de CPM foram avaliados visualmente por 16 estudantes da licenciatura em medicina nuclear nas escalas de cores Cool, Gray, Gray Invert, Thermal e Warm. Para a escala de cores Cool, a análise das imagens de CPM foi realizada através de um sistema de classificação semiquantitativo por scores. As restantes escalas de cores foram avaliadas por comparação com a análise das imagens efetuada com escala de cores Cool. Resultados/Discussão – Para a escala de cores Cool, a variabilidade interoperador revelou a existência de diferenças estatisticamente significativas entre todos os participantes (p<0,05), o que se pode atribuir à subjetividade da avaliação visual. Os resultados relativos às escalas de cores Gray e Gray Invert foram os mais próximos da perfusão do miocárdio observada com a escala Cool, considerando-se escalas de cores alternativas na análise visual dos estudos de CPM. Para as escalas de cores Thermal e Warm os resultados foram mais divergentes, não se considerando adequadas para a avaliação visual dos estudos de CPM. Conclusão – A escala de cores influencia a avaliação qualitativa da perfusão na CPM.

Are Complications Associated With the Repiphysis(®) Expandable Distal Femoral Prosthesis Acceptable for Its Continued Use?

BACKGROUND: Reconstruction of the distal femur after resection for malignant bone tumors in skeletally immature children is challenging. The use of megaprostheses has become increasingly popular in this patient group since the introduction of custom-made, expandable devices that do not require surgery for lengthening, such as the Repiphysis(®) Limb Salvage System. Early reports on the device were positive but more recently, a high complication rate and associated bone loss have been reported. QUESTIONS/PURPOSES: We asked: (1) what are the clinical outcomes using the Musculoskeletal Tumor Society (MSTS) scoring system after 5-year minimum followup in patients treated with this prosthesis at one center; (2) what are the problems and complications associated with the lengthening procedures of this implant; and (3) what are the specific concerns associated with revision of this implant? METHODS: At our institute, between 2002 and 2007, the Repiphysis(®) expandable prosthesis was implanted in 15 children (mean age, 8 years; range, 6-11 years) after distal femoral resection for malignant bone tumors. During this time, the general indication for use of this implant was resection of the distal femur for localized malignant bone tumors in pediatric patients. Alternative techniques used for this indication were modular prosthetic reconstruction, massive (osteoarticular or intercalary) allograft reconstruction, or rotationplasty. Age and tumor extension were the main factors to decide on the surgical indication. Of the 15 patients who had this prosthesis implanted during reconstruction surgery, five died with the implant in situ or underwent amputation before 5 years followup and the remaining 10 were evaluated at a minimum of 5 years (mean, 104 months; range, 78-140 months). No patients were lost to followup. These 10 patients were long-term survivors and underwent the lengthening program. They were included in our study analysis. The first seven lengthening procedures were attempted in an outpatient setting; however, owing to pain and burning sensations experienced by the patients, the procedures failed to achieve the desired lengthening. Therefore, other procedures were performed with the patients under general anesthesia. We reviewed clinical data at index surgery for all 15 patients. We further analyzed the lengthening procedures, implant survival, radiographic and functional results, for the 10 long-term survivors. Functional results were assessed according to the MSTS scoring system. Complications were classified according to the International Society of Limb Salvage (ISOLS) classification system. RESULTS: Nine of the 10 survivors underwent revision of the implant for mechanical failure. They had a mean MSTS score of 64% (range, 47%-87%) before revision surgery. At final followup the 10 long-term surviving patients had an average MSTS score of 81% (range, 53%-97%). In total, we obtained an average lengthening of 39 mm per patient (range, 17-67 mm). Exact expansion of the implant was unpredictable and difficult to control. Nine of 10 of the long-term surviving patients underwent revision surgery of the prosthesis-eight for implant breakage and one for stem loosening. At revision surgery, six patients had another type of expandable prosthesis implanted and three had an adult-type megaprosthesis implanted. In five cases, segmental bone grafts were used during revision surgery to compensate for loss of bone stock. CONCLUSIONS: We could not comfortably expand the Repiphysis(®) prosthesis in an outpatient setting because of pain experienced by the patients during the lengthening procedures. Furthermore, use of the prosthesis was associated with frequent failures related to implant breakage and stem loosening. Revisions of these procedures were complex and difficult. We no longer use this prosthesis and caution others against the use of this particular prosthesis design. LEVEL OF EVIDENCE: Level IV, therapeutic study.

The cytokinesis-block micronucleus (CBMN) assay in human populations exposed to styrene: a systematic review and meta-analysis

Styrene is a building-block of several compounds used in a wide array of materials and products. The most important human exposure to this substance occurs in industrial settings, especially among reinforced-plastics industry workers. The effect of occupational exposure to styrene on cytogenetics biomarkers has been previously reviewed with positive association observed for chromosomal aberrations, and inconclusive data for the micronucleus assay. Some limitations were noted in those studies, including inadequate exposure assessment and poor epidemiological design. Furthermore, in earlier studies micronuclei frequency was measured with protocols not as reliable as cytokinesis-block micronucleus (CBMN) assay. Aim of the present systematic review and meta-analysis is to investigate genomic instability and DNA damage as measured by the CBMN assay in lymphocytes of subjects exposed to styrene. A total of 11 studies published between 2004 and 2012 were included in the meta-analysis encompassing 479 styrene-exposed workers and 510 controls. The quality of each study was estimated by a quality scoring system which ranked studies according to the consideration of major confounders, exposure characterization, and technical parameters. An overall increase of micronuclei frequencies was found in styrene-exposure workers when compared to referents (meta-MR 1.34; 95% CI 1.18–1.52), with significant increases achieved in six individual studies. The consistency of results in individual studies, the independence of this result from major confounding factors and from the quality of the study strengthens the reliability of risk estimates and supports the use of the CBMN assay in monitoring genetic risk in styrene workers.

Exploring the potential role of allostatic load biomarkers in risk assessment of patients presenting with depressive symptoms

Background: Depression is a major health problem worldwide and the majority of patients presenting with depressive symptoms are managed in primary care. Current approaches for assessing depressive symptoms in primary care are not accurate in predicting future clinical outcomes, which may potentially lead to over or under treatment. The Allostatic Load (AL) theory suggests that by measuring multi-system biomarker levels as a proxy of measuring multi-system physiological dysregulation, it is possible to identify individuals at risk of having adverse health outcomes at a prodromal stage. Allostatic Index (AI) score, calculated by applying statistical formulations to different multi-system biomarkers, have been associated with depressive symptoms. Aims and Objectives: To test the hypothesis, that a combination of allostatic load (AL) biomarkers will form a predictive algorithm in defining clinically meaningful outcomes in a population of patients presenting with depressive symptoms. The key objectives were: 1. To explore the relationship between various allostatic load biomarkers and prevalence of depressive symptoms in patients, especially in patients diagnosed with three common cardiometabolic diseases (Coronary Heart Disease (CHD), Diabetes and Stroke). 2 To explore whether allostatic load biomarkers predict clinical outcomes in patients with depressive symptoms, especially in patients with three common cardiometabolic diseases (CHD, Diabetes and Stroke). 3 To develop a predictive tool to identify individuals with depressive symptoms at highest risk of adverse clinical outcomes. Methods: Datasets used: ‘DepChron’ was a dataset of 35,537 patients with existing cardiometabolic disease collected as a part of routine clinical practice. ‘Psobid’ was a research data source containing health related information from 666 participants recruited from the general population. The clinical outcomes for 3 both datasets were studied using electronic data linkage to hospital and mortality health records, undertaken by Information Services Division, Scotland. Cross-sectional associations between allostatic load biomarkers calculated at baseline, with clinical severity of depression assessed by a symptom score, were assessed using logistic and linear regression models in both datasets. Cox’s proportional hazards survival analysis models were used to assess the relationship of allostatic load biomarkers at baseline and the risk of adverse physical health outcomes at follow-up, in patients with depressive symptoms. The possibility of interaction between depressive symptoms and allostatic load biomarkers in risk prediction of adverse clinical outcomes was studied using the analysis of variance (ANOVA) test. Finally, the value of constructing a risk scoring scale using patient demographics and allostatic load biomarkers for predicting adverse outcomes in depressed patients was investigated using clinical risk prediction modelling and Area Under Curve (AUC) statistics. Key Results: Literature Review Findings. The literature review showed that twelve blood based peripheral biomarkers were statistically significant in predicting six different clinical outcomes in participants with depressive symptoms. Outcomes related to both mental health (depressive symptoms) and physical health were statistically associated with pre-treatment levels of peripheral biomarkers; however only two studies investigated outcomes related to physical health. Cross-sectional Analysis Findings: In DepChron, dysregulation of individual allostatic biomarkers (mainly cardiometabolic) were found to have a non-linear association with increased probability of co-morbid depressive symptoms (as assessed by Hospital Anxiety and Depression Score HADS-D≥8). A composite AI score constructed using five biomarkers did not lead to any improvement in the observed strength of the association. In Psobid, BMI was found to have a significant cross-sectional association with the probability of depressive symptoms (assessed by General Health Questionnaire GHQ-28≥5). BMI, triglycerides, highly sensitive C - reactive 4 protein (CRP) and High Density Lipoprotein-HDL cholesterol were found to have a significant cross-sectional relationship with the continuous measure of GHQ-28. A composite AI score constructed using 12 biomarkers did not show a significant association with depressive symptoms among Psobid participants. Longitudinal Analysis Findings: In DepChron, three clinical outcomes were studied over four years: all-cause death, all-cause hospital admissions and composite major adverse cardiovascular outcome-MACE (cardiovascular death or admission due to MI/stroke/HF). Presence of depressive symptoms and composite AI score calculated using mainly peripheral cardiometabolic biomarkers was found to have a significant association with all three clinical outcomes over the following four years in DepChron patients. There was no evidence of an interaction between AI score and presence of depressive symptoms in risk prediction of any of the three clinical outcomes. There was a statistically significant interaction noted between SBP and depressive symptoms in risk prediction of major adverse cardiovascular outcome, and also between HbA1c and depressive symptoms in risk prediction of all-cause mortality for patients with diabetes. In Psobid, depressive symptoms (assessed by GHQ-28≥5) did not have a statistically significant association with any of the four outcomes under study at seven years: all cause death, all cause hospital admission, MACE and incidence of new cancer. A composite AI score at baseline had a significant association with the risk of MACE at seven years, after adjusting for confounders. A continuous measure of IL-6 observed at baseline had a significant association with the risk of three clinical outcomes- all-cause mortality, all-cause hospital admissions and major adverse cardiovascular event. Raised total cholesterol at baseline was associated with lower risk of all-cause death at seven years while raised waist hip ratio- WHR at baseline was associated with higher risk of MACE at seven years among Psobid participants. There was no significant interaction between depressive symptoms and peripheral biomarkers (individual or combined) in risk prediction of any of the four clinical outcomes under consideration. Risk Scoring System Development: In the DepChron cohort, a scoring system was constructed based on eight baseline demographic and clinical variables to predict the risk of MACE over four years. The AUC value for the risk scoring system was modest at 56.7% (95% CI 55.6 to 57.5%). In Psobid, it was not possible to perform this analysis due to the low event rate observed for the clinical outcomes. Conclusion: Individual peripheral biomarkers were found to have a cross-sectional association with depressive symptoms both in patients with cardiometabolic disease and middle-aged participants recruited from the general population. AI score calculated with different statistical formulations was of no greater benefit in predicting concurrent depressive symptoms or clinical outcomes at follow-up, over and above its individual constituent biomarkers, in either patient cohort. SBP had a significant interaction with depressive symptoms in predicting cardiovascular events in patients with cardiometabolic disease; HbA1c had a significant interaction with depressive symptoms in predicting all-cause mortality in patients with diabetes. Peripheral biomarkers may have a role in predicting clinical outcomes in patients with depressive symptoms, especially for those with existing cardiometabolic disease, and this merits further investigation.

Risk perception and correlates of alcohol use among out-of-school youth in motor parks in Lagos State, Nigeria

Background and Aim: The prevalence of alcohol use has increased globally. Out-of-school youth are a vulnerable group who might have missed opportunities for learning healthy behaviours in a formal school environment. The purpose of this study was to determine the risk perception, pattern of use, and correlates of alcohol use among out-of-school youth in Lagos, Nigeria. Methods: A cross-sectional study was conducted among 380 out-of-school youth in motor parks in Lagos State, Nigeria, using interviewer administered questionnaires. Results: The lifetime prevalence of alcohol use was 61.1%, while 55.5% were current drinkers. Beer (57.3%) was the most consumed type of alcohol, followed by distilled spirits (29.8%). Using the CAGE scoring system, more than half (57.8%) of the current drinkers had a drinking problem. Almost three quarters (70.1%) had experienced at least one episode of alcohol intoxication within the past month. A considerable number of current drinkers (63.5%) desired to reduce their alcohol intake or stop drinking, while 45.5% had made unsuccessful attempts to do so within the past year. Only 28.9% had received assistance to quit or reduce their drinking and of these less than half (39.3%) received assistance from a professional or healthcare worker. Males were more likely to be current drinkers and to have experienced episodes of alcohol intoxication. Parental and peer drinking were associated with alcohol use but not with intoxication. Conclusions: It is important to design specific programmes to reduce alcohol use among out-of-school youth in these settings.

Estudo da maturação eritróide com base no CD35 e no CD44 em síndromes mielodisplásicas

As Síndromes Mielodisplásicas (SMD) representam um grupo de doenças clonais da célula pluripotencial hematopoiética caracterizadas por hematopoiese ineficaz e aumento do risco de progressão para Leucemia Mieloblástica Aguda. Considerando que a linha eritróide está muitas vezes afectada em SMD e a avaliação da displasia desta linha representa um desafio na análise imunofenotípica de medulas mielodisplásicas, o objectivo deste trabalho foi estudar a expressão de CD44 e de CD35 na maturação eritróide normal e a forma como essa expressão é afectada em SMD. Este estudo foi efectuado em 16 amostras de medula óssea (MO) normais/reactivas e em 48 amostras de MO de indivíduos diagnosticados com SMD e sem tratamento. De acordo, com a Organização Mundial de Sáude (OMS) os doentes com SMD foram classificados em CRDM (n=20), AREB-1 (n=15) e AREB-2 (n=13) e de acordo com o International Prognostic Scoring System (IPSS) em Baixo risco (n=5), Intermédio-1 (n=8) e Intermédio-2 e Alto risco (n=14). A caracterização imunofenotípica foi efectuada através de um protocolo de imunofluorescência directa de marcação-lise-lavagem, utilizando os anticorpos monoclonais: anti-CD34; anti-HLA-DR; anti-CD117; anti-CD44; anti-CD35; anti-CD45, anti-CD123 e anti-CD133. Para a análise, procedeu-se à identificação e quantificação das células de linha eritróide em MO total e nos diferentes estádios de maturação e à avaliação da expressão de CD44 e de CD35. Os resultados deste estudo revelaram o CD35 como um marcador precoce na diferenciação eritróide normal e um aumento da expressão de CD44 e da percentagem de eritroblastos em SMD, sendo este aumento mais evidenciado nos estádios mais avançados da doença.

Concluiu-se, principalmente, que: em relação ao Índice de Enfermeiros e Score TISS, verificaram-se variações acentuadas, quer na necessidade de trabalho de enfermagem quer na gravidade dos doentes, durante 365 dias; comparando a média anual de TISS obtida com o diagnóstico atual da situação na UCIDEM, existe uma dotação desfasada de acordo com o que foi medido pelo TISS; e que a carga de trabalho dos enfermeiros não é distribuída equitativamente pelos turnos

International flavours

It is an Olympic year and we have just witnessed the fantastic games hosted by Rio de Janeiro. Well done to team USA for winning the most medals overall but also well done to so many other nations and individuals who performed so well or were ambassadors in other ways. Teenage swimmer Yusra Mardini who swam for the refugee team and South Africa's Wayde van Niekerk who broke the longstanding 400 m record of Michael Johnson that has stood since 1999. Of course, we must mention sprinter Usain Bolt and swimmer Michael Phelps, who have now transcended superstar status and entered a new level of icon. My personal highlight was the sportsmanship witnessed in the 5000 m when American Abbey D’Agostino was accidentally felled by New Zealand runner Nikki Hamblin. D’Agostino helped Hamblin back to her feet but slumped to the track after realising her own injury. Hamblin helped her up and stayed with her so that both completed the race. The International Olympic Committee has awarded both with the prestigious Pierre de Coubertin award, also known as the International Fair Play Trophy. Fair play is of paramount importance in publishing in peer-reviewed papers. At CLAE we try and maintain, as do other journals, this by ensuring double blind peer review and allowing authors to select the most appropriate handling editor for their submission. Our handling editors are placed across the world (2 in Europe, 1 in the Americas, 1 in Australia and 1 in Asia) and part of their role is to encourage submissions from their region. Over the last decade we certainly have seen more and more papers from places that haven’t previously published in CLAE. In this issue of CLAE we have a true international blend of papers. We have papers from authors from the UK, USA, Iran, Jordan, France, Poland, Turkey, Nigeria, France, Spain and Brazil. I think it's a testament to the continued success of the journal that we are attracting new writers from so many parts of the world and retain papers from more established authors and research centres. We do continue to attract many weaker papers that are rejected early in the review process. Often these will be unexceptional case reports or papers describing a surgical technique. Case reports are published but only those that offer something original and especially those with interesting photographs. In this issue you will see Professor James Wolffsohn (UK) has an interesting paper around a lot of the focus of his recent research activity into clinical evaluation of methods of correcting presbyopia. In this paper he highlights predictors to aid success of presbyopic contact lenses. If you have been involved in any clinical work or research in the field of dry eye disease then you will know well the CLDEQ (Contact Lens Dry Eye Questionnaire) devised by Robin Chalmers and her colleagues (USA). This issue of CLAE details the latest research using the CLDEQ-8 (the 8 item version of the CLDEQ). The Shahroud Eye Cohort Study has produced many papers already and in this issue we see Fotouhi Akbar (Iran) looking at changes in central and peripheral corneal thickness over a five year period. These days we use a lot of new instrumentation, such as optical low-coherence reflectometry. In this issue Emre Güler (Turkey) compares that to a new optical biometry unit. Dry eye is more common and in this issue we see a study by Oluyemi Fasina (Nigeria) to investigate the disease in adults in South-West Nigeria. The TearLab™ is now commonly used to investigate osmolarity and Dorota Szczesna-Iskander (Poland) looks at measurement variability of this device. Following the theme of dry eyes and tear testing Renaud Laballe (France) looks at the use of scleral lenses as a reservoir-based ocular therapeutic system. In this issue we have a couple of papers looking at different aspects of keratoconus. Magdalena Popiela (UK) looks at demographics of older keratoconic patients in Wales, Faik Orucoglu (Turkey) reports a novel scoring system for distinguishing keratoconus from normal eyes, Gonzalo Carracedo (Spain) reports the effect of rigid gas permeable lens wear on dry eye in keratoconus and Hatice Nur Colak (Turkey) compares topographic and aberrations in keratoconus. Other interesting papers you will find are Mera Haddad (Jordan) investigates contact lens prescribing in Jordan, Camilla Fraga Amaral (Brazil) offers a report on the use of ocular prosthetics, Naveed Ahmed Khan (Malaysia) reports of the use of dimethyl sulfoxide in contact lens disinfectant and Michael Killpartrick (UK) offers a short piece with some useful advice on contamination risk factors that may occur from the posterior surface of disposable lenses. So for this issue I would say that the Gold Medal for biggest contribution in terms of papers has to go to Turkey. I could have awarded it to the UK too, but Turkey has three full papers and the UK has two plus one short communication. Turkey is also one of the countries that has shown the largest increase in submissions over the last decade. Finally, welcome aboard to our newest Editorial Board Member Nicole Carnt from Australia. Nicole has been an active researcher for many years and acted as a reviewer for CLAE many times in the past. We look forward to working with you.

Effects of radiation therapy on the structure and function of the pelvic floor muscles of patients with cancer in the pelvic area : a systematic review

Purpose Radiation therapy (RT) is often recommended in the treatment of pelvic cancers. Following RT, a high prevalence of pelvic floor dysfunctions (urinary incontinence, dyspareunia, and fecal incontinence) is reported. However, changes in pelvic floor muscles (PFMs) after RT remain unclear. The purpose of this review was to systematically document the effects of RT on the PFM structure and function in patients with cancer in the pelvic area. Methods An electronic literature search using Pubmed Central, CINAHL, Embase, and SCOPUS was performed from date of inception up to June 2014. The following keywords were used: radiotherapy, muscle tissue, and pelvic floor. Two reviewers selected the studies in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement (PRISMA). Out of the 369 articles screened, 13 met all eligibility criteria. The methodological quality was assessed using the QualSyst scoring system, and standardized mean differences were calculated. Results Thirteen studies fulfilled all inclusion criteria, from which four were of good methodological quality. One presented strong evidence that RT affects PFM structure in men treated for prostate cancer. Four presented high-level evidence that RT affects PFM function in patients treated for rectal cancer. Meta-analysis was not possible due to heterogeneity and lack of descriptive statistics. Conclusion There is some evidence that RT has detrimental impacts on both PFMs’ structure and function. Implications for cancer survivors A better understanding of muscle damage and dysfunction following RT treatment will improve pelvic floor rehabilitation and, potentially, prevention of its detrimental impacts.

Risco e regulação emocional em idade pré-escolar: A qualidade das interações dos educadores de infância como potencial moderador

A investigação tem demonstrado que as crianças em desvantagem social enfrentam muitos desafios e estão mais vulneráveis a desenvolver dificuldades ao nível da regulação emocional, sendo extremamente relevante identificar fatores protetores que moderem esta vulnerabilidade, de modo a identificar formas de alterar as trajetórias desenvolvimentais. No presente estudo, foi analisado o papel moderador das interações do educador de infância no desenvolvimento da regulação emocional. Os participantes incluíram 345 crianças em idade pré-escolar de dois ambientes sociais distintos: em risco sociocultural (n=183) e em situação de não risco sociocultural. A regulação emocional foi avaliada através de um questionário ao educador, o Emotion Regulation Checklist (ERC; Shields & Cichetti, 1997). A qualidade das interações do educador de infância com as crianças foi observada através de uma escala de observação, o Classroom Assessment Scoring System (CLASS; Pianta, La Paro & Hamre, 2008). Os educadores avaliaram ainda a sua relação com cada criança participante através da Student-Teacher Rating Scale (STRS; Pianta, 2001). Análises multi-grupo multinível indicaram que no grupo de crianças de risco socicultural, em salas em que os educadores de infância estabeleciam interações com mais qualidade a nível emocional e organizacional, as crianças demonstraram competências de regulação emocional mais elevadas, o que sugere o importante papel das interações dos educadores de infância com as crianças no desenvolvimento da regulação emocional.

Evaluación de desenlace: trasplante meniscal versus segunda meniscectomía

Introducción: El incremento de pacientes sintomáticos de rodilla y la osteoartrosis en jóvenes con limitadas posibilidades terapéuticas después de una meniscectomía, genera la búsqueda de alternativas terapéuticas. A pesar que es poco utilizado en Colombia, el trasplante meniscal es una propuesta para el manejo sintomático. Según cifras norteamericanas, se practican entre 700.000 a 1.500.000 artroscopias de rodilla anualmente, el 50% termina en meniscectomía y de este un 40% persisten sintomáticos. Métodos: Estudio de cohorte retrospectivo, con el objetivo de evaluar dolor (Escala Visual Análoga-EVA) y funcionalidad (Escala de Tegner y Lysholm) en los pacientes a quienes se les realizó trasplante meniscal o meniscectomía por segunda vez, entre los años 2007 a 2015. Resultados: A partir de los 6 meses la EVA mostró una tendencia a la mejoría en el grupo de trasplante meniscal, pasando de Moderado a Leve (p: <0.000). La Escala de Tegner y Lysholm cambió de Pobre a Bueno en el grupo de segunda meniscectomía (p= 0.008) y de Bueno a Excelente en el grupo trasplantado (p=0.225). La calificación promedio de la EVA en el grupo de trasplante presentó mejoría (p=<0.000), a diferencia del grupo de segunda meniscectomía (p=0.591). La escala de Tegner y Lysholm, mostró significancia estadística con tendencia a la mejoría en el grupo de segunda meniscectomía. Discusión: Los resultados muestran que con trasplante meniscal hay mejoría del dolor y la funcionalidad versus un segunda meniscectomía. Para fortalecer la evidencia de este tratamiento son necesarios estudios prospectivos complementarios.

Índice del perfil del donante renal (KDPI) como factor pronóstico del trasplante

La enfermedad renal crónica ha aumentado a nivel mundial y nacional, mientras que el número de donantes viene en descenso, y los pacientes en lista de espera aumentan. Los donantes cadavéricos son una opción para estos pacientes, y han sido utilizados en últimos años para aumentar los órganos disponibles. La evaluación de la calidad de estos es importante para optimizar su uso. Estudio analítico tipo cohorte retrospectiva, cálculo de KDPI en donantes cadavéricos, seguimiento función renal creatinina sérica 1 mes, 3 meses, 6 meses y un año. Correlación supervivencia del injerto, función renal, KDPI y EPTS. Análisis de supervivencia y regresión logística con variables del donante, receptor y acto quirúrgico.
