Therapeutic Physical Exercise for Dysmenorrhea: A Scoping Review.

Dysmenorrhea affects many women of reproductive age. Physical exercise has been used as an effective intervention for pain reduction and to improve well-being. Physiotherapy, involving movement and exercise, can be effective in relieving menstrual pain and provide additional benefits.

Exposure to silver and titanium dioxide nanoparticles at supra-environmental concentrations decreased sperm motility and affected spermatozoa subpopulations in gilthead seabream, Sparus aurata.

Marine pollution by nanoparticles (NPs) can be reprotoxic for fish and disturb successful reproduction of wild populations. In gilthead seabream (Sparus aurata), a mild effect on sperm motility was observed after exposure to high concentrations of silver NPs. Considering the great heterogeneity traits within a sperm sample, it is possible that NPs affect spermatozoa accordingly, modulating subpopulation profile.

Silver nanoparticles and silver ions indistinguishably decrease sperm motility in Pacific oysters (Magallana gigas) after short-term direct exposure.

The present study aimed to evaluate the reprotoxicity of environmental (0.25 μg.L) and supra-environmental (25 μg.

Shipping can be achieved but cargo arrives with damage - titanium dioxide nanoparticles affect the DNA of Pacific oyster sperm.

Titanium dioxide nanoparticles (TiO NP) were reported to be reprotoxic in humans and fish. However, the effects of these NP on the reproduction of marine bivalves, namely oysters, remain unknown. Thus, a short-term (1 h) direct exposure of sperm of the Pacific oyster (Crassostrea gigas) to two TiO NP concentrations (1 and 10 mg.

Ex vivo exposure to titanium dioxide and silver nanoparticles mildly affect sperm of gilthead seabream (Sparus aurata) - A multiparameter spermiotoxicity approach.

Nanoparticles (NP) are potentially reprotoxic, which may compromise the success of populations. However, the reprotoxicity of NP is still scarcely addressed in marine fish. Therefore, we evaluated the impacts of environmentally relevant and supra environmental concentrations of titanium dioxide (TiO: 10 to 10,000 μg·L) and silver NP (Ag: 0.

Mild Effects of Sunscreen Agents on a Marine Flatfish: Oxidative Stress, Energetic Profiles, Neurotoxicity and Behaviour in Response to Titanium Dioxide Nanoparticles and Oxybenzone.

UV filters are potentially harmful to marine organisms. Given their worldwide dissemination and the scarcity of studies on marine fish, we evaluated the toxicity of an organic (oxybenzone) and an inorganic (titanium dioxide nanoparticles) UV filter, individually and in a binary mixture, in the turbot (). Fish were intraperitoneally injected and a multi-level assessment was carried out 3 and 7 days later.

Incontinence Quiz: Translation, validation, and reproducibility in Portuguese women.

Aim: The purpose of the present study was to translate and validate the Incontinence Quiz (IQ) questionnaire into a Portuguese version.

Methods: The Portuguese version of the 14-item Incontinence Quiz was prepared following translation and back-translation procedures and was tested on a pilot group of 10 women. Internal consistency (Cronbach's α), test-retest reliability (intraclass correlation coefficient [ICC]), and construct validity (using two indicators: education level and being a qualified health professional) were assessed in 141 women from the staff of two higher education institutions.

Association Between Physical Activity Level and Pelvic Floor Muscle Variables in Women.

In order to investigate the potential impact of physical activity (PA) on pelvic floor muscle (PFM) function, a cross-sectional study was made to analyse the association between PA level and vaginal resting pressure (VRP) and PFM strength and endurance. Thirty-eight continent women and 20 women with stress urinary incontinence (SUI) aged 19 to 49 years were enrolled in the study. PFM variables were assessed by manometry.

Urinary incontinence and disordered eating in female elite athletes.

Objectives: To evaluate the association between urinary incontinence and disordered eating, in elite female athletes.

Design: This cross-sectional study included 744 young and healthy Portuguese women: 372 elite athletes and 372 age-matched non-athletes, mean age 21±5.3years.

Mobilization and collection of peripheral blood stem cells in multiple myeloma patients older than 65 years.

Over the past 10 years, the incidence of multiple myeloma (MM) has been greater among individuals >65 years old than in younger age groups. This retrospective study of peripheral blood stem cell mobilization and harvesting examined patients of various age groups who were afflicted with this pathology. One group of 17 patients ≥65 years of age with MM (group A) were mobilized between 2002 and 2009 and compared with 33 consecutive patients of younger ages with the same diagnosis treated in 2008 and 2009 (group B).

Ancestim (recombinant human stem cell factor, SCF) in association with filgrastim does not enhance chemotherapy and/or growth factor-induced peripheral blood progenitor cell (PBPC) mobilization in patients with a prior insufficient PBPC collection.

Up to a third of autologous transplantation candidates fail to mobilize hematopoietic progenitors into the peripheral blood with chemotherapy and/or growth factor treatment, thus requiring innovative mobilization strategies. In total, 20 cancer patients unable to provide adequate PBPC products after a previous mobilization attempt were treated with ancestim (20 microg/kg/day s.c.

Risk factors for acute graft-versus-host disease in patients undergoing transplantation with CD34+ selected blood cells from HLA-identical siblings.

A study on 315 patients undergoing transplantation with CD34+ selected blood cells from HLA-identical siblings was performed to determine risk factors for acute GVHD (aGVHD). Recipients of a dose of CD34+ cells (x 10(6)/kg) of 2 or less, more than 2 to 4, and more than 4 had a cumulative incidence of aGVHD grades I-IV of 21%, 35%, and 43%, respectively (log-rank P =.01); similarly, recipients of a dose of CD3+ cells (x 10(6)/kg) of 0.

Umbilical cord blood processing with the Optipress II blood extractor.

Background: We have previously shown that UC blood (UCB) units can be volume-reduced manually, in a closed system, without major losses of nucleated and CD34(+) cells and without the addition of exogenous material. Our aim was to use an automated method for the separation of the UCB components using the Optipress II, extractor, with the 'buffy-coat' collection in a standardized volume.

Methods: After centrifugation, the 51 UCB units were separated into the three blood components, plasma, buffy coat (BC) and red cells, using the Optipress II.

The number of donor CD3(+) cells is the most important factor for graft failure after allogeneic transplantation of CD34(+) selected cells from peripheral blood from HLA-identical siblings.

This study analyzed the characteristics of 257 HLA-identical sibling transplants of granulocyte colony-stimulating factor-mobilized peripheral blood progenitor cells depleted of T cells by CD34(+) positive selection (allo-PBT/CD34(+)) for their effect on the incidence of graft failure. Twenty-four patients developed graft failure (actuarial probability, 11%; 95% confidence interval, 7.1-14.

Central nervous system (CNS) tuberculosis following allogeneic stem cell transplantation.

Tuberculosis is an uncommon infectious complication after stem cell transplantation. We report a patient who presented with a brain mass, 3 months after pulmonary tuberculosis had been diagnosed and while he was receiving triple antituberculous therapy. He had extensive chronic GVHD.

Single- versus dual-platform assays for human CD34+ cell enumeration.

We comparatively assessed CD34+ cell quantification by two of the recently available single platform assays, the IMAGN 2000 STELLer (Immucor, Lisbon, Portugal) microvolume fluorimetry and the ProCOUNT (BD-ENZIfarma, Lisbon, Portugal) flow cytometry, with our "in-house" dual-platform flow cytometric assay. The performance of the methods was evaluated by linearity and reproducibility tests. The linearity study, over a range of 0-1,200 CD34+ cell/microl, gave a good linear relationship for the three methods, with R(2) > 0.

Analysis of surface markers on CD34+ cells, isolated from cord blood and G-CSF primed peripheral blood.

We report a comparative study of the expression of multilineage and adhesion molecules on CD34+ cells isolated from human umbilical cord blood (CB) and G-CSF-mobilized peripheral blood progenitor cells (PBPC) from healthy volunteers. The major difference found between the two sources of CD34+ populations was the expression of CD54 molecule, which was higher in CB in comparison to PBPC.

Work hours, sleep patterns and fatigue among merchant marine personnel.

A field study of work and sleep patterns among commercial merchant marine personnel is reported. Data collected over a 10-30-d period from 141 subjects aboard eight ships included information concerning work-rest schedules, sleep timing, alertness on the job and critical fatigue. The data indicate that watchstanders on the 4-on, 8-off schedule show considerable disruption in their sleep.

Umbilical cord blood processing: volume reduction and recovery of CD34+ cells.

One of the main problems for the establishment of umbilical cord blood (UCB) banks is the storage space needed for the frozen samples. The aim of this study was to find a method of reducing the volume of UCB units without major losses of the haematopoietic progenitor-CD34+ cells. The UCB was collected into a triple blood bag system, in which the anti-coagulant had been previously adjusted.

Sleep reduction in night-shift workers: is it sleep deprivation or a sleep disturbance disorder?

Two explanations of the reported reduction in night-shift workers' sleep length have emerged. One argues that these reductions in sleep are related to sleep disturbances which may require medical treatment as disorders. The other argues that sleep reduction is mainly due to a sleep deficit caused by the voluntary choice to delay sleep onset and reduce the sleep duration which requires a systems approach aimed at increasing sleep length and reducing the effect of a sleep deficit at the workplace.
