Upper-Body Exercises With External Resistance Are Well Tolerated and Enhance Muscle Activity in People With Hemophilia
2019
Abstract Background Conventional nonresisted therapeutic exercises for people with hemophilia involve a careful, low-intensity approach to avoid injuries. Externally resisted exercise is highly efficient for increasing muscle strength in healthy adults but its feasibility for people with hemophilia remains unknown. Objective The purpose of this study was to evaluate muscle activity during upper-body rehabilitation exercises with 2 types of external resistance and without external resistance (conventional) and to examine tolerability, kinesiophobia, and possible adverse effects derived from the session. Design This was a cross-sectional study. Methods Twelve people with hemophilia A/B (11 wi…
Feasibility, safety and muscle activity during flywheel vs traditional strength training in adult patients with severe haemophilia
2021
INTRODUCTION: Eccentric training has been associated with several specific physiological adaptations. The flywheel machine is one of the easiest ways of performing eccentric overload training. However, no studies evaluated its feasibility, safety and muscle activity in patients with haemophilia (PWH).AIM: To evaluate feasibility and safety and compare muscle activity during flywheel vs weight machine knee extension exercise in severe PWH.METHODS: Eleven severe PWH [mean age of 33.5 (8.1) years] participated in this cross-sectional study after receiving prophylactic treatment. Surface electromyography (EMG) signals were recorded for the rectus femoris during the knee extension exercise perfo…
Missed opportunities for tuberculosis investigation in a municipal hospital in Ghana: evidence from patient exit interviews
2020
Abstract Background We assessed coverage of symptom screening and sputum testing for tuberculosis (TB) in hospital outpatient clinics in Ghana. Methods In a cross-sectional study, we enrolled adults (≥18 years) exiting the clinics reporting ≥1 TB symptom (cough, fever, night sweats or weight loss). Participants reporting a cough ≥2 weeks or a cough of any duration plus ≥2 other TB symptoms (per national criteria) and those self-reporting HIV-positive status were asked to give sputum for testing with Xpert MTB/RIF. Results We enrolled 581 participants (median age 33 years [IQR: 24–48], 510/581 [87.8%] female). The most common symptoms were fever (348, 59.9%), chest pain (282, 48.5%) and coug…
Post-reproductive aged women: a lost generation in the cervical cancer screening programme
2020
The aims of the study were to find out why some post-reproductive aged women did not participate in the organised cervical cancer screening programme in Latvia and to clarify factors that would motivate them to take part. A cross-sectional study was carried out between January and July 2017 among female patients in three general practitioner (GP) practices. GP practice nurses used the Latvian national health service database to identify women aged 25–70 who had not participated in the organised programme for the last 3 years. Participants were asked to complete a specially developed questionnaire. The results were then compared between three age groups: 25–34, 35–49 and 50–70 years. Include…
Learning Curve and Fatigue Effect of Flicker Defined Form Perimetry
2011
To evaluate the learning curve and fatigue effect of flicker defined form (FDF) perimetry.Prospective cross-sectional study.One hundred forty-one eyes of 75 healthy subjects were included in the study. Every subject was measured 3 times on 3 different days within 3 months. Differences among the tests were analyzed for mean sensitivity (MS), mean deviation (MD), pattern standard deviation (PSD), reliability indices, test duration, and test points5% and0.5% in 75 right eyes on the basis of linear mixed models for repeated measurements. To assess the effect of fatigue, differences of MS, MD, and PSD values between 66 left and right eyes were evaluated regarding alterations between these 3 exam…
Metabolically healthy polycystic ovary syndrome (MH-PCOS) and metabolically unhealthy polycystic ovary syndrome (MU-PCOS): a comparative analysis of …
2013
Study question Is it possible to distinguish metabolically healthy polycystic ovary syndrome (MH-PCOS) from metabolically unhealthy PCOS (MU-PCOS) by simple diagnostic tools such as body mass index (BMI), waist/hip ratio (WHR), at-risk category suggested by Androgen Excess Society (AES) and visceral adiposity index (VAI)? Summary answer VAI could be an easy and useful tool in clinical practice and in population studies for assessment of MU-PCOS. What is known already VAI is a good indicator of insulin sensitivity and cardiometabolic risk in oligo-ovulatory women with PCOS. Study design, size, duration We conducted a cross-sectional study of 232 women with PCOS in a university hospital setti…
Patient satisfaction with a rapid diagnosis of suspicious breast lesions: Association with distress and anxiety
2017
Few studies have explored with standard measures patient satisfaction with care at the time of the diagnosis through rapid diagnostic pathways. This study aimed to assess satisfaction levels at the time of the diagnosis in a One-Stop Breast Unit and to examine associations with psychological states. An anonymous cross-sectional survey was conducted at a single center's One-Stop Breast Unit, to assess patient satisfaction regarding several aspects of the Unit. Two days after the diagnosis, 113 participants completed self-reported questionnaires evaluating satisfaction (Out-Patsat35), anxiety (State Anxiety Inventory), and psychological distress (Distress Thermometer). Overall, patients were …
Validity and Reliability of the Spanish Version of the "Abuse Assessment Screen" among Pregnant Women.
2016
Objective: To assess the reliability, accuracy, and construct validity of the Spanish Abuse Assessment Screen (AAS) among pregnant women using the Spanish version of Index of Spouse Abuse (ISA) as a reference standard. Design and Sample: Cross-sectional survey. A total of 1,329 pregnant women were selected in nine primary care centers during 2008-2009. Measures: The Spanish ISA was self-administered first, followed by the AAS, administered by the midwife. Sensitivity, specificity, and predictive values of the Spanish AAS were compared with the Spanish version of the ISA as a reference standard. Results: Percentage of agreement between initial and retest administration of the Spanish AAS was…
No phenotypic differences for polycystic ovary syndrome (PCOS) between women with and without type 1 diabetes mellitus.
2013
Context: Women with type 1 diabetes mellitus (DM1) have a higher prevalence of polycystic ovary syndrome (PCOS) than the general population. Objective: The aim of this study was to clarify, in DM1 women with PCOS(PCOS-DM1), the influence of insulin therapy and glycemic control and evaluate the hormonal and phenotypic differences with age-matched and body mass index (BMI)-matched women with PCOS without diabetes. Design, Setting, and Patients: We evaluated 103 DM1 women with and without PCOS treated with intensive insulin therapy; 38 age-matched and BMI-matched women with PCOS without diabetes were compared in a cross-sectional study. Outcome Measurements: Clinical, anthropometric, and metab…
Self-Reported Restrictive Eating, Eating Disorders, Menstrual Dysfunction, and Injuries in Athletes Competing at Different Levels and Sports
2021
The purpose of this study was to investigate the prevalence of self-reported restrictive eating, current or past eating disorder, and menstrual dysfunction and their relationships with injuries. Furthermore, we aimed to compare these prevalences and associations between younger (aged 15–24) and older (aged 25–45) athletes, between elite and non-elite athletes, and between athletes competing in lean and non-lean sports. Data were collected using a web-based questionnaire. Participants were 846 female athletes representing 67 different sports. Results showed that 25%, 18%, and 32% of the athletes reported restrictive eating, eating disorders, and menstrual dysfunction, respectively. Higher ra…
