Prevalence of Parental Alcohol Problems among a General Population Sample of 28,047 Norwegian Adults: Evidence for a Socioeconomic Gradient
2021
The aim of the study presented here was to estimate the prevalence of parental alcohol problems during childhood in a general population of Norwegian adults, and to investigate associations between parental alcohol problems during childhood and lower socioeconomic status in adulthood. This cross-sectional study recruited 28,047 adults (≥18 years) to an online health survey (Norwegian Counties Public Health Surveys). We evaluated demographic and socioeconomic measures and responses to a shortened version of the Children of Alcoholics Screening Test (CAST-6) scale to assess whether respondents perceived parental alcohol consumption during childhood as problematic. Respondents reported parenta…
Comparison of Lateral Abdominal Musculature Activation during Expiration with an Expiratory Flow Control Device Versus the Abdominal Drawing-in Maneu…
2020
Background and Objectives: The purpose of the present study was to quantify and compare lateral abdominal musculature thickness, including the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles, via rehabilitative ultrasound imaging (RUSI) during the use of the expiratory flow control device (EFCD) versus the classic abdominal drawing-in maneuver (ADIM). Materials and Methods: A cross-sectional observational pilot study. Twenty-one women were recruited and assessed the thickness of each muscle (TrA, IO, and EO) by ultrasound imaging at rest, during the ADIM, and during expiration with the EFCD. Waist circumference was also measured under the same circumstan…
Changes in beverage consumption from pre-pregnancy to early pregnancy in the Norwegian Fit for Delivery study.
2015
AbstractObjectiveTo describe changes in consumption of different types of beverages from pre-pregnancy to early pregnancy, and to examine associations with maternal age, educational level and BMI.DesignCross-sectional design. Participants answered an FFQ at inclusion into a randomized controlled trial, the Fit for Delivery (FFD) trial, in median gestational week 15 (range: 9–20), reporting current consumption and in retrospect how often they drank the different beverages pre-pregnancy.SettingEight local antenatal clinics in southern Norway from September 2009 to February 2013.SubjectsFive hundred and seventy-five healthy pregnant nulliparous women.ResultsPre-pregnancy, 27 % reported drinkin…
Activation-Induced Rigidity in Neurologically and Cognitively Healthy Individuals Aged 18-90 Years: A Cross-Sectional Study.
2021
Background: Rigidity is a key clinical feature of Parkinson’s disease (PD), but in a very early phase of the disease it may be absent and can be enhanced through active movements of the arm contralateral to the one being tested. Objective: To evaluate in a large cohort of neurologically and cognitively healthy (NCH) subjects aged 18–90 years if activation-induced rigidity (AR) is present in all age classes, and if there are biological differences between subjects showing AR (AR+) and not showing AR (AR-). Methods: 2,228 NCH subjects categorized as young adult (18–44 years), adult (45–64 years), elderly (65–74 years), and old/oldest-old (75–90 years) were included in the analysis, and underw…
Cardiopulmonary loading in motocross riding
2007
The present study was designed to examine physiological responses during motocross riding. Nine Finnish A-level motocross riders performed a 15-min ride at a motocross track and a test of maximal oxygen uptake (VO2max) in the laboratory. Cardiopulmonary strain was measured continuously during the ride as well as in the VO2max test. During the ride, mean VO2 was 32 ml x kg(-1) x min(-1) (s = 4), which was 71% (s = 12) of maximum, while ventilation (V(E)) was 73% (s = 15) of its maximum. The relative VO2 and V(E) values during the riding correlated with successful riding performance (r = 0.80, P < 0.01 and r = 0.79, P < 0.01, respectively). Mean heart rate was maintained at 95% (s = 7) of its…
Effect of Isometric Upper-Extremity Exercises on the Activation of Core Stabilizing Muscles
2007
Abstract Tarnanen SP, Ylinen JJ, Siekkinen KM, Malkia EA, Kautiainen HJ, Hakkinen AH. Effect of isometric upper-extremity exercises on the activation of core stabilizing muscles. Objective To evaluate whether isometric exercises for the upper extremities could sufficiently activate core stabilizing muscles to increase muscle strength. Design Cross-sectional study. Setting Department of physical medicine and rehabilitation at a Finnish hospital. Participants Healthy adult women (N=20). Interventions Not applicable. Main Outcome Measures Peak isometric strength of the back and abdominal muscles was measured and relative loading in 5 test exercises was evaluated by surface electromyography. Re…
Heterogeneity in Cystic Echinococcosis Management Among Spanish Centers: Results from a National Survey
2020
The aim of the study was to evaluate the availability of different procedures, diagnostic tests, and treatments, as well as the procedures and techniques used in the management of cystic echinococcosis (CE) in Spain. This was a cross-sectional study performed from September to December 2018 in Spain. A survey directed to CE-treating clinicians was conducted to collect information regarding the center characteristics and the different protocols of management followed. Thirty-nine centers among 76 contacted centers participated in the survey, most of them belonging to the public health system and attending both adult and children. The median number of patients with CE attended during the last…
Whole-body vibration and disorders of the spine
1987
This cross-sectional study is based on interviews and medical examinations of 352 operators of earth-moving machines who had been exposed to whole-body vibrations for at least three years. In addition, available X-rays showing different parts of the spines of 251 machine operators who had been exposed to vibration for at least ten years were used for evaluation. One hundred and forty-nine of the operators were asked about discomfort occurring immediately after an eight-hour work shift. The group of exposed persons was compared with a control group of 215 non-exposed persons. The percentage of subjects reporting spinal discomfort was much higher for the exposed group than for the non-exposed…
Evaluation of saliva as a complementary technique to the diagnosis of COVID-19:a systematic review
2021
Background Infectious disease coronavirus 2019 (COVID-19) is caused by the SARS-CoV-2 virus, and it mainly affects the upper respiratory tract. The gold standard for its diagnosis is real-time reverse transcription polymerase chain reaction (RT-qPCR) performed on a nasopharyngeal swab. In contrast, testing saliva has significant advantages as a diagnostic method. Material and Methods We searched for articles evaluating saliva as a diagnostic method for COVID-19 on the PUBMED/MEDLINE, WEB OF SCIENCE, COCHRANE, and SCIELO platforms. We initially found 233 articles and 20 were selected for inclusion following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol: 18 c…
Prevalence of cervical human papillomavirus infection and types among women immigrated to Sicily, Italy.
2009
We determined the prevalence of human papillomavirus (HPV) cervical infection and HPV genotypes among 115 women immigrating to Sicily (Italy), with regard to abnormal cytology and socio-behavioral characteristics in a cross-sectional, observational study. Information was collected with the help of cultural mediators/translators. HPV-DNA was assayed by the INNOLiPA HPV assay and a nested PCR/sequencing method. Sixty (52.2%) women came from sub-Saharan Africa and 55 (47.8%) from Eastern Europe. HPV infection was found in 55 (47.8%) women. The most frequent types were the oncogenic types HPV-16 (7.8%), HPV-18 and 51 (6.0% each), HPV-52 (5.2%), 31, 53, and 68 (4.3% each). Twenty-seven (23.5%) w…
