Occupational exposure to lead (Pb) requires continuous surveillance to assure, as much as possible, safe and healthful working conditions. This study addresses the suitability of assessing Pb exposure in relevant workers using their exhaled breath condensate (EBC). This study enrolled workers of two different Pb processing industries characterized by moderate and high Pb exposure levels in the work environment, and a group of non-exposed individuals working in offices who served as baseline for Pb exposure. The EBC-Pb of workers reflected the Pb levels in the work environment of all three settings, although the relationship with B-Pb was not clear. The lack of correlation between EBC-Pb and B-Pb most probably indicates the time lag for Pb to enter in the two body pools. The EBC-Pb seems to reflect immediate exposure, providing a prompt signature of Pb in the environmental that may interact directly with the organ. By delivering short-term evaluation of exposure, EBC-Pb represents a clear advantage in biomonitoring and may become an interesting tool for estimating organ burden. 相似文献

AIM:
qualitative study, which aimed to identify the barriers that influence nursing care practices related to the sexuality of women with gynecological and breast cancer.METHODS:
the study was conducted with 16 professionals of the nursing area (nurses, nursing technicians and nursing assistants) from two sectors of a university hospital situated in the state of São Paulo, Brazil. The data was collected using semi-structured, in-depth individual interviews. All the interviews were recorded and the participants'' responses were identified and categorized using Content Analysis.RESULTS:
three major themes were identified. These are as follows: 1) barriers related to the biomedical model; 2) barriers related to institutional dynamics and 3) barriers related to the social interpretations of sexuality.CONCLUSIONS:
the results of this study showed that the systematized inclusion of this issue in nursing care routines requires changes in the health paradigm and in the work dynamic, as well as reflection on the personal values and social interpretations related to the topic. A major challenge is to divest sexuality of the taboos and prejudices which accompany it, as well as to contribute to the nursing team being more aware of the difficulties faced by women with gynaecological and breast cancer. 相似文献84.

Objective
The objective of this study was to assess changes in upper trapezius myoelectric activity and pain in patients with nonspecific neck pain after a single session of acupuncture (ACP).Methods
A blinded randomized clinical trial was conducted. Fifteen patients with nonspecific neck pain and 15 healthy participants were enrolled in a randomized, single-blinded, crossover study. Each participant was subjected to a single session of ACP and sham acupuncture (SACP). The electromyography (EMG) signal of the upper trapezius muscle was recorded during different step contractions of shoulder elevation force (15%-30% maximal voluntary contraction) before and after ACP treatment.Results
Significant effects were confirmed after the treatment (ACP and SACP) for Numeric Rating Scale scores (F1,28 = 51.61; P < .0001) and pain area (F1,2 = 32.03; P < .0001). Significant decreases in the EMG amplitude were identified for the nonspecific neck pain group (NPG) (F1,112 = 26.82; P < .0001) and the healthy participant group (HPG) (F1,112 = 21.69; P < .0001) after ACP treatment. No differences were identified between the ACP and SACP treatment protocols for Numeric Rating Scale score (NPG: F1,28 = 0.95; P = .33), pain area (NPG: F1,28 = 1.97; P = .17), or EMG amplitude (NPG: F1,112 = 0.47; P = .49; HPG: F1,112 = 0.75; P = .38).Conclusion
The effect of ACP at acupoints triple energizer 5 and large intestine 11 triple energizer 5, or in close proximity, contributes to pain relief among patients with nonspecific neck pain. The electromyographic analysis indicated a greater resistance to muscle fatigue and decrease of activity of the upper trapezius muscle among healthy participants and patients with nonspecific neck pain. 相似文献86.

IntroductionParavalvular leak (PVL) is a common serious complication associated with prosthetic valve implantation.ObjectiveThe aim of this study was to report our single-center experience in a retrospective review and to analyze possible predictors of success.MethodsWe performed 33 percutaneous PVL closures in 26 patients (54% female, mean age 65±13 years). All mitral prostheses were studied previously with 3D transesophageal echocardiography (TEE), and aortic prostheses with 2D/3D TEE. 3D TEE and fluoroscopy were used for the assessment, planning, and guidance of the interventions. Twelve patients also underwent computed tomography angiography for better characterization of anatomic details.ResultsEighteen patients (69.2%) were admitted due to heart failure (New York Heart Association [NYHA] III or IV, seven (26.9%) because of heart failure and hemolysis, and one (3.8%) due to hemolysis only. Regarding the leaks, 46.2% were in aortic and 53.8% in mitral prostheses, 88.5% in mechanical and 7.7% in biological prostheses, and 3.8% in transcatheter aortic valve implants. All the aortic patients had severe aortic regurgitation. Furthermore, all mitral patients but one had moderate to severe or severe mitral regurgitation. Closure was successful in 17 patients (65.4%), partially successful in four (15.4%) and unsuccessful in five (19.2%). After the procedure, 69% were in NYHA I-II. Hemolysis worsened in three patients despite successful closure; all required further valvular surgery and two died. Regarding angiographic and echocardiographic procedural success, we analyzed age, gender, type of prosthesis (mechanical or biological), location (aortic or mitral), clinical data, maximum leak diameter, anatomic regurgitant orifice, leak location (anterior, posterior, inferior and lateral for mitral leaks and left, right and non-coronary sinus for aortic leaks), and number of devices (plugs) used for closure. No parameters presented a significant relationship with success excepting previous hemolysis. There was a relationship between clinical improvement and reduction of PVL (p=0.0001). In follow-up, cardiac-related events (new hospital admissions, cardiac valvular surgery, need for transfusion) were more frequent in patients with partially successful or unsuccessful closure (p=0.012). There was a relationship between cardiac-related events and death (p=0.029).ConclusionPercutaneous PVL closure has emerged as an alternative treatment for PVL. Predictors of procedural success are difficult to establish. Survival is related to reduction of regurgitation and improvement in NYHA functional class. 相似文献

Magnetic resonance imaging (MRI) is currently considered an essential complementary method for diagnosis in many conditions. Exponential growth in its use is expected due to the aging population and a broader spectrum of clinical indications. Growth in its use, coupled with an increasing number of pacemaker implants, implantable cardioverter‐defibrillators and cardiac resynchronization therapy, has led to a frequent clinical need for this diagnostic modality in patients with cardiac implantable electronic devices (CIED). This clinical need has fueled the development of devices specifically designed and approved for use in a magnetic resonance (MR) environment under certain safety conditions (MR‐conditional devices). More than a decade after the introduction of the first MR‐conditional pacemaker, there are now several dozen MR‐conditional devices with different safety specifications. In recent years, increasing evidence has indicated there is a low risk to MRI use in conventional (so‐called non‐MR‐conditional) CIED patients in the right circumstances. The increasing number, as well as the greater diversity and complexity of implanted devices, justify the need to standardize procedures, by establishing institutional agreements that require close collaboration between cardiologists and radiologists. This consensus document, prepared jointly by the Portuguese Society of Cardiology and the Portuguese Society of Radiology and Nuclear Medicine, provides general guidelines for MRI in patients with CIED, ensuring the safety of patients, health professionals and equipment. In addition to briefly reviewing the potential risks of MRI in patients with CIED and major changes to MRI‐conditional devices, this article provides specific recommendations on risk‐benefit analysis, informed consent, scheduling, programming strategies, devices, monitoring and modification of MRI sequences. The main purpose of this document is to optimize patient safety and provide legal support to facilitate easy access by CIED patients to a potentially beneficial and irreplaceable diagnostic technique. 相似文献
