Pressure levels in the trochanter area according to repositioning at different degrees of inclination in healthy subjects

ObjectivesPatient repositioning is a recommended intervention to prevent or treat pressure ulcers (PUs). One option under consideration is the tailored repositioning according to patient characteristics, but more knowledge is needed on how different repositioning patterns influence on skin pressure. To determine what degree of inclination of the body in bed generates more pressure in the trochanteric region. Additionally, to analyze the influence of factors such as gender, age and anthropometric characteristics in the variations of this pressure.MethodsAnalytical cross-sectional study. Body Mass Index (BMI), lean mass and fat mass were measured in healthy volunteers subject to different inclinations (90°, 60° and 30°) in right lateral decubitus. Pressure was measured with a capacitive surface.ResultsIn total, 146 subjects were included, of which 45 were men and 101 women. The results showed pressure differences due to the inclination according to gender and anthropometric values, being statistically significant in men at 90° and 60°, and in women at 30°. (hombres 90° p = 0,026, 60° p = 0,049; mujeres 30° p = 0,036) según prueba Brown-Forsythe.ConclusionsThere are differences in the pressures of the trochanteric zone depending on anthropometric factors and by gender, in different body positions. Obese people exerted a higher pressure in the trochanter area at 30° of body inclination than overweight, normal weight and underweight people, respectively. From the clinical point of view, these findings invite to consider a possible differentiation in the repositioning interventions of the patients, according to gender and BMI, as a preventive strategy for PUs.     

Nurse-led patient education for persons suffering from a venous leg ulcer in outpatient's clinics and homecare settings: A scoping review

Aim of this studyTo provide an overview of the available nurse-led individualized educational interventions, for persons with Venous Leg Ulcer (VLUs) in an outpatient or homecare settings.Materials and methodsFor this scoping review, a search was performed between December 2019 and January 2020. To identify sources of evidence a systematic search was conducted in PubMed, CINAHL, Embase, PsychINFO, Web of Science and LiSSa as well as in clinical trial registers to identify sources of evidence. All types of evidence associated with a nurse led-intervention were included.ResultsFifteen sources of evidence met the inclusion criteria. Educational sessions varied in modality, content and duration. Education sessions were face to face and supported by written materiel. The content focused on compression therapy and exercises. The duration and numbers of sessions varied. The most reported health related outcomes was wound healing.ConclusionThis scoping review provides a broad overview of the available evidence and ongoing research for individualized nurse-led education persons with VLUs. Variability in the literature was found, which suggests that more intervention studies are needed to test and evaluate efficacy of nurse-led patient education.     

多学科管理下鸟氨酸氨甲酰基转移酶缺乏症妇女连续三次妊娠分娩健康儿一例

本文报告1例鸟氨酸氨甲酰基转移酶缺乏症患者3次妊娠,最终在多学科管理下分娩一健康新生儿的诊疗经过。2013年患者首次妊娠,孕28周出现急性高氨血症收入上海交通大学医学院附属新华医院,诊断为鸟氨酸氨甲酰基转移酶缺乏症。给予低蛋白饮食及降血氨治疗,并在多学科管理下于孕32周剖宫产一男婴,但该男婴生后第3天死亡。基因分析提示患者及其新生儿鸟氨酸氨甲酰基转移酶基因均存在c.583G>A(G195R)突变。2015年患者再次自然妊娠,但产前诊断提示胎儿为男性,且鸟氨酸氨甲酰基转移酶基因存在同一位点纯合突变,于孕21周引产终止妊娠。2017年借助体外受精-胚胎移植及植入前基因诊断技术第3次妊娠,并在多学科管理下最终顺利分娩一名健康男婴。     

Looking for opportunities to co-enroll: The DISCOVERY study experience

BackgroundConducting high-quality stroke trials is complex and costly. Often these trials compete for the attention of researchers and the availability of patients. Enrolling patients in more than one study concurrently has the potential to accelerate recruitment into individual studies. DISCOVERY is a multicenter, inception cohort study of cognitive impairment and dementia following ischemic or hemorrhagic stroke. At the request of site investigators, a DISCOVERY committee reviews individual studies for approval of possible concurrent co-enrollment into DISCOVERY. The purpose of this report is to summarize the characteristics and outcomes of studies reviewed by committee for possible co-enrollment.MethodsThis analysis covers studies reviewed from 07/01/2020 to 04/26/2022 by the Site Management Committee (SMC) of the DISCOVERY Recruitment and Retention Core. Characterization of each study included study type, number and length of follow-up visits, and whether there were protocol-required blood draws, brain imaging studies, or cognitive tests. Studies were scored for patient burden and scientific overlap with Discovery. The primary outcome was SMC approval to co-enroll.Results59 studies were reviewed, and 69.5% (n = 41, 21 clinical trials; 20 observational studies) were found by the SMC to be appropriate for co-enrollment. Higher patient burden and greater scientific overlap with DISCOVERY reduced the rates of approval for co-enrollment.ConclusionA large number of diverse stroke studies are being run concurrently across the DISCOVERY study network, however, about two-thirds of the studies were considered appropriate for consideration of co-enrollment. Future studies should study how co-enrollment might improve trial network efficiency.     

Uso de la anticoncepción con solo gestágenos en atención primaria: estudio GESTAGAP

AimTo estimate the prevalence of use of progestin-only contraceptive among women who request reversible contraception in Primary Care (PC).DesignMulticentre cross-sectional study.SettingPrimary Care Health Care Centres (Madrid).ParticipantsWomen aged 16-50 years old, users of reversible contraception, who speak Spanish, and had attended the Primary Care Centre in the last year.Main measurementsPrimary outcome: contraceptive method used: Contraception with progestins-only (yes/no). Age, parity, country of origin, type of contraceptive method used, reason for choice, source of information, satisfaction with the contraceptive method. Telephone survey.ResultsA total of 417 women were interviewed. The median age was 30.3 years (SD: 7.7). Spanish 69%, and 82% of participants had secondary or university studies. More than half (57%) were nulliparous. The type of contraceptive used included: progestins only: 14%, combined hormonal contraceptive: 74%, copper IUD: 2%, and condom 10%. The prevalence of use of “progestins-only” was 13.9% (95% CI: 10.6-17.2). Medroxyprogesterone acetate injection was the most progestin-only method used (4.6%), desogestrel oral pill (4.1%), IUD-levonorgestrel IUD (3.9%), and etonogestrel subdermal implant (1.9%). The family doctor was the prescriber in 71% of the women. Satisfaction: high (range 9-10). Using only progestogens was associated with older age, being non-Spanish, breastfeeding, and having a medical contraindication for combined contraception (P < 0.05).ConclusionsThe prevalence of use for progestins was 14%, satisfaction was very high for all contraceptive methods. The user profile for the only progestins-only corresponds to older, and non-Spanish women with conditions such as breastfeeding or contraindications for other contraceptives.
