The purpose of this cross-sectional, correlational study was to validate the factors that are related to dysmenorrhea in Taiwanese adolescents. The specific aims were to describe the perceived dysmenorrhea pain symptom experience (SE), related self-care strategies (SCS), and perceived effectiveness of self-care strategies (PESS); to explore the relationships between SE, SCS, and PESS; and to explore the influence of contextual factors on SE, SCS, and PESS. A conceptual framework based on the revised Symptom Management Model was developed and guided this study. A nonprobability sample of 165 adolescent participants was recruited from a technology university located in southern Taiwan. Inclusion criteria for participants were: (1) Taiwanese female adolescent, (2) age 15-19 years old, and (3) willing to participate in this study. All participants and their parents completed the consent forms and completed the questionnaires in their classrooms during free studying time. Five instruments were used and data was analyzed by using the SPSS Version 14.0 including descriptive statistical techniques, Pearson’s correlations, ANOVA, and multiple regression analysis. The findings showed the prevalence of dysmenorrhea in this sample was 87.3%. There were 82.4% of participants who reported dysmenorrhea had influenced their daily activity, and 12.7% of participants who reported school absenteeism because of dysmenorrhea. Most of participants used self–care strategies for dysmenorrhea including avoiding cold food or drinks, drinking brown sugar and ginger soup, etc. The most frequently used self-care strategies and their effectiveness were described. Age, age of the first period, total menstrual years, eating cold food or drinks, self-care strategies, and mother’s perceived support of self-care strategies were significantly related to the log of symptom experience of dysmenorrhea. Total menstrual years and self-care strategies were identified as significant predictors of dysmenorrhea. This study added to the body of nursing science regarding dysmenorrhea in Taiwanese adolescents. In particular, the findings supported the existence of relationships between self-care strategies and perceived effectiveness of self-care strategies. Building on these findings, future research should be conducted to design interventions that reduce the pain associated with dysmenorrhea for this population. / text

Background: Exercise associated muscle cramping (EAMC) is a common medical condition encountered by endurance athletes, yet information regarding EAMC in cyclists in lacking. Aim of the study: To determine the epidemiology, clinical characteristics, and independent risk factors associated with EAMC in cyclists participating in a mass participation cycling event. Design: Cross-sectional study Setting: 2016 Cape Town Cycle Tour (CTCT), South Africa Participants: 22560 consenting cycle race entrants Methods: Epidemiological data (lifetime prevalence and annual incidence) and clinical characteristics (main muscle groups affected, timing of onset, severity [mild - severe] and frequency of serious forms of EAMC [sEAMC]) in cyclists with a history of EAMC (hEAMC) are reported on. A multiple regression analysis was applied in order to determine if the following factors were associated risk factors for EAMC in cyclists with a hEAMC: chronic disease composite score, cycling training / racing history (years of recreational cycling, years of participation in distance cycling events > 2 hours, average number of training sessions per week, average weekly cycling distance in the last 12 months, and average training speed), history of chronic disease (history of cardiovascular disease [CVD], risk factors for CVD, symptoms of CVD, metabolic/hormonal disease, respiratory disease, gastrointestinal disease, nervous system/psychiatric disease, kidney/bladder disease, haematological/immune system disease, and cancer) and allergies, and history of cycling injuries. Results: A total of 35914 cyclists entered the race, 27349 completed the online pre-race medical screening questionnaire, and 22560 gave informed consent for the use of their data in this study (62.82% of all race entrants). The lifetime prevalence of EAMC was 30.6%, with an annual incidence of 18.7%. The quadriceps muscle group was the most commonly affected muscle group (47.7%), the most common time period for the onset of EAMC was during the fourth quarter of the race (63.0%), and mild (less than 5 minutes) EAMC occurred more frequently (67.0%) than other forms of EAMC. Serious EAMC was reported by 5.6% of the study population, and included whole body EAMC (3.2%) and EAMC associated with dark urine (2.2%). Novel independent risk factors associated with an increased risk of hEAMC in cyclists were: a higher chronic disease composite score (PR=1.34 per 2 unit increase; p<0.0001), a history of any allergies (PR=1.17; p<0.0001), a history of an acute onset injury (PR=1.31; p<0.0001), a history of a gradual onset injury (PR=1.29; p<0.0001), and increased number of years participating in cycling events of > 2 hours (PR=1.34 per 2 unit increase, p<0.0001). Increased number of years as a recreational cyclist (PR=0.96 per 5 unit increase, p=0.0012) and increased average weekly training/racing frequency in the last 12 months (PR=0.95 per 2 unit increase, p=0.0015) were associated with a decreased risk of EAMC. From the univariate analysis, we identified a significantly higher prevalence of lifetime hEAMC in male cyclists (PR=2.16; p<0.0001), and a higher prevalence of hEAMC in the ≥51-year age category (37.6%). Conclusion: One in three cyclists report a lifetime hEAMC. In cyclists with a hEAMC, the quadriceps muscle group is the most commonly affected muscle group, EAMC commonly occurs in the last quarter of the race, most EAMC cases are reported as mild, and sEAMC is not common. The results from this study could influence the future prevention and management programmes of EAMC in recreational cyclists, and assist medical personnel in the planning and implementation of medical care at mass participation cycling events. A higher chronic disease composite score, a history of allergies, a history of injury (acute onset or gradual onset) and training / racing variables are novel independent risk factors associated with a hEAMC in cyclists taking part in a mass participation cycling event. Risk factors for EAMC need to be taken into consideration when implementing prevention and management programmes of EAMC in cyclists. Clinicians should also consider that in some cases, EAMC may be associated with underlying chronic diseases or allergies, and/or the medications used to treat such conditions. In addition, injury history and training variables need to be considered in the prevention and management of EAMC in cyclists.

El presente proyecto de un parche hecho con fibras naturales y aceites esenciales de eucalipto, mentol y uña de gato muestra su viabilidad en base a una investigación hecha a mujeres limeñas de los niveles socioeconómicos A y B. De esta manera, el análisis permitió identificar un grupo de mujeres que sufren de cólicos menstruales intensos y a quienes las pastillas, y demás métodos usuales para combatirlos, no les funcionan. Asimismo, se identificó que habría disponibilidad a cambiar los medicamentos tradicionales por un producto natural que sea de fácil uso y que les permita realizar sus actividades cotidianas sin problema. Por último, se vio que el público objetivo identificado prefiere ahorrar tiempo al momento de adquirir los medicamentos o cualquier otro método que use para combatir los cólicos, por lo que mostraron interés en comprarlo y recibirlo en su casa directamente. Para poner en marcha el proyecto, se procedió a hacer una investigación de mercado, industria, consumidor, competidores, así como de proveedores. Adicionalmente, se elaboraron planes estratégicos para desarrollar el proyecto: Plan Estratégico, Plan de Marketing, Plan de Operaciones, Plan de Recursos Humanos, Plan Financiero y Plan de Responsabilidad Social, los cuales contienen estrategias y objetivos concisos para poder encaminar el proyecto. Como resultado de lo descrito anteriormente, con una inversión inicial de S/. 49,149, se obtendrán utilidades netas de S/. 39,990 para el primer año, S/. 129,811 para el segundo y S/. 304,186 para el tercero. / The present project of a patch made of natural fibers and three essential oils: eucalyptus, menthol and cat’s claw, shows its viability based on our research on women who live in Lima and belong to socioeconomic status A and B. In this way, the analysis allowed us to identify a group of women who suffer from intense menstrual cramps and whom pills and other traditional methods don’t help to ease the pain. Likewise, we identified that women are willing to change usual medicine to an easy-to-use product which allows them to continue doing their daily activities. Finally, we noticed the target segment prefers to save time when buying their usual medicine or any other method they use to ease menstrual cramps. That is why they showed interest in buying our product online and getting it delivered to their houses. To begin with the project, we carried out a market research, industry, consumer, competitors and suppliers research. Additionally, we elaborated strategic plans to develop our project: Strategic Plan, Marketing Plan, Operations Plan, Human Resources Plan, Finances Plan and Social Responsibility Plan, which contain precise strategies and objectives to lead the project. As a result of what’s been described previously, investing S/. 49,149, we will get net profits of S/. 39,990 for the first year, S/. 129,811 for the second year, and S/. 304,186 for the third year. / Trabajo de investigación

The purpose of this study was to assess the effect of performance feedback on Athletic Trainers’ (ATs) perceived knowledge (PK) and likelihood to pursue continuing education (CE). The investigation was grounded in the theories of “the definition of the situation” (Thomas & Thomas, 1928) and the “illusion of knowing,” (Glenberg, Wilkinson, & Epstein, 1982) suggesting that PK drives behavior. This investigation measured the degree to which knowledge gap predicted CE seeking behavior by providing performance feedback designed to change PK. A pre-test post-test control-group design was used to measure PK and likelihood to pursue CE before and after assessing actual knowledge. ATs (n=103) were randomly sampled and assigned to two groups, with and without performance feedback. Two independent samples t-tests were used to compare groups on the difference scores of the dependent variables. Likelihood to pursue CE was predicted by three variables using multiple linear regression: perceived knowledge, pre-test likelihood to pursue CE, and knowledge gap. There was a 68.4% significant difference (t101= 2.72, p=0.01, ES=0.45) between groups in the change scores for likelihood to pursue CE because of the performance feedback (Experimental group=13.7% increase; Control group= 4.3% increase). The strongest relationship among the dependent variables was between pre-test and post-test measures of likelihood to pursue CE (F2,102=56.80, p<0.01, r=0.73, R2=0.53). The pre- and post-test predictive relationship was enhanced when group was included in the model. In this model [YCEpost=0.76XCEpre-0.34 Xgroup+2.24+E], group accounted for a significant amount of unique variance in predicting CE while the pre-test likelihood to pursue CE variable was held constant (F3,102=40.28, p<0.01,: r=0.74, R2=0.55). Pre-test knowledge gap, regardless of group allocation, was a linear predictor of the likelihood to pursue CE (F1,102=10.90, p=.01, r=.31, R2=.10). In this investigation, performance feedback significantly increased participants’ likelihood to pursue CE. Pre-test knowledge gap was a significant predictor of likelihood to pursue CE, regardless if performance feedback was provided. ATs may have self-assessed and engaged in internal feedback as a result of their test-taking experience. These findings indicate that feedback, both internal and external, may be necessary to trigger CE seeking behavior.

Hintergrund: Der genaue Pathomechanismus zur Entstehung des benignen Faszikulations- Crampus-Syndrom ist nicht bekannt, und es wurde noch nie eine größere Anzahl dieser Patienten mittles des threshold trackings untersucht. Material und Methoden: 18 Patienten mit einem BFCS und 15 gesunde Probanden wurden mithilfe des threshold trackings, welches eine Methode zur Messung von Exzitabilitätsparametern von peripheren Nerven in vivo ist, untersucht und die Ergebnisse verglichen. Ergebnisse: Die stärksten Unterschiede zeigten sich im threshold electrotonus, der current/threshold relationship und der stimulus-response-curve. Im threshold electrotonus war insbesondere die Schwellenwertzunahme auf hyperpolarisierende Reize signifikant geringer bei einer Reizstärke von -40%, -70% und -100% des Kontrollimpulses (p < 0,01). Die current/threshold relationship war in hyperpolasierender Richtung bei den BFCS Patienten steiler als bei der gesunden Kontrollgruppe (p < 0,05). Außerdem benötigten sie eine deutlich geringere Reizintensität, um 50% des maximalen Summenaktionspotentials des Muskels auszulösen (p < 0,05). Schlussfolgerung: Die Ergebnisse weisen auf eine veränderte Expression oder Kinetik der HCN-Kanäle an peripheren Nerven der Patienten mit einem BFCS hin und geben folglich neue Hinweise auf die Entstehung dieser Erkrankung. Da zum ersten Mal ein Zusammenhang zwischen der Veränderung der HCN-Kanäle und dem BFCS gezeigt werden konnte, sollten sich zukünftige Studien darauf konzentrieren, genauere Informationen über diese Pathologie zu erlangen.

Bakgrund: Felaktiga torrvikter är ett problem inom hemodialysvården. Det kan orsaka vårdskada i form av komplikationer och lidande, med symtom som trötthet, blodtrycksfall och sendrag för dialyspatienter. Det finns ett behov av implementering av evidensbaserade metoder som minskar risken för fel i torrviktsbestämning. Bioimpedansmätning beskrivs i litteraturen som ett lovande hjälpmedel för bestämning av torrvikt Syfte: Undersöka effekten av bioimpedansledd torrviktskorrigering, på symtom som hemodialyspatienter kan erfara under och efter dialysbehandling. Metod: Experimentell intervention, i form av veckovis korrigering av torrvikt med vägledning av bioimpedansspektroskopi, utförd med single-case-design och multiple base- line. Urvalet bestod av sex strategiskt utvalda hemodialyspatienter. Resultat: Interventionen hade ringa effekt på förekomst av intradialytiska symtom. Bland studiens deltagare förelåg sällan samvariation mellan förekomst av blodtrycksfall och/eller sendrag och felaktig torrvikt. Däremot förelåg positivt samband mellan symtombörda och differens mellan predialytisk vikt och torrvikt. Bioimpedansmätningarna avslöjade dessutom kliniskt relevant varians i torrvikt över tid. Slutsats: Även om interventionen inte hade bevisad effekt på de beroende variablerna, är det inte uteslutet att noga monitorering av vätskebalans med bioimpedansmätare och korrigering av torrvikt kan förebygga uppkomst av intradialytiska symtom. I vissa subgrupper kan bioimpedansmätning också bidra till förbättrad blodtryckskontroll. Dialyspatienters torrvikt visade sig kunna variera med flera kilogram per vecka, varför fixerad torrvikt kan vara ett dilemma för vissa individer. Bioimpedansmätning bland hemodialyspatienter kan underlätta identifiering av individuella riskfaktorer för intradialytiska symtom och vara ett verktyg som bidrar till utvecklingen mot personcentrerad vård med större patientdelaktighet och individualiserade mål. / Background: Inaccurate dry weight is a problem in hemodialysis care. It can cause health damage in the form of suffering and complications such as fatigue, intradialytic hypotension (IDH) and cramps for dialysis patients. There is a need for implementation of evidence-based practices that reduce the risk of error in dry weight assessment. Bioelectrical impedance is described in literature as a promising tool for assessment of dry weight.Objective: Examine the effect of bioimpedance guided dry weight correction on symptoms that hemodialysis patients may experience during and after dialysis. Method: Experimental intervention in the form of weekly assessment of dry weight with the guidance of bioimpedance spectroscopy, performed with single-case design and multiple baseline. The sample consisted of six strategically selected hemodialysis patients. Results: The intervention had little effect on the prevalence of intradialytic symptoms. Among the study participants, the occurrence of IDH and / or cramps and inaccurate dry weight rarely correlated. However, there was positive correlation between symptoms and the difference between predialytic weight and dry weight. Bioimpedance measurement also revealed clinically relevant variance in dry weight over time. Conclusion: Although the intervention had no proven effect on the dependent variables, it is possible that careful monitoring of fluid balance with bioimpedance measurement and correction of dry weight can help prevent intradialytic symptoms. In certain subgroups bioelectrical impedance may also contribute to improved blood pressure control. Dialysis patients' dry weight was found to vary several kilograms per week; fixated dry weight may therefore be a dilemma for some individuals. Bioelectrical impedance among hemodialysis patients may facilitate identification of individual risk factors for intradialytic symptoms and be a tool that contributes to the development of person-centered care with greater patient participation and individualized goals.
