Menopausal symptoms in an intercultural context: a comparison between German women,Chinese women and migrant Chinese women using the Menopause Rating Scale (MRS II)

Objective

What are the differences between the occurrence of menopausal symptoms in German women, migrant Chinese women in Germany and Chinese women in their native country? Can these potential discrepancies be explained by sociocultural differences? What are the differences in menopausal symptoms in connection with the consumption of soya?

Patient study group and methods

Cross-sectional study 2005–2008. Survey of three groups of women aged between 45 and 60 years (native German women in Berlin, migrant Chinese women in several German cities, Chinese women in Beijing) with an evaluated set of questionnaires surveying socio-demographic data, use of hormone therapy, migration/acculturation, MRS II and other areas.

Results

A total of 2,109 questionnaires were sent out and a 41 % response rate was achieved, although this varied greatly across the three individual study groups. The results of the MRS II factor analysis were almost identical for German women and migrant Chinese women, but there were some differences in content compared to the Chinese study group. Chinese women surveyed in Beijing reported severe symptoms significantly less frequently in all three symptom groups (factors) of MRS II than the German women and the migrant Chinese women, but the values from the German women and migrant Chinese women surveyed are relatively similar. In all three study groups there are no significant differences in the stated severity of the symptoms, regardless of whether soya is consumed frequently or less frequently.

Conclusion

The question whether the differences found are solely cultural or migration-related must be examined in further studies. The special experiences and situation in life of migrant women should be taken into particular account by attending physicians during the care and treatment of women in this phase of life.     

Differential diagnosis of intramedullary osteosarcomas

Intramedullary high-grade osteosarcomas are aggressive tumors with a high metastatic capacity. The many subtypes and variants of these tumors often make the differential diagnosis difficult. Therefore, a critical review of both radiology and histomorphology is mandatory. Low-grade central osteosarcomas are a completely different tumor group. Due to their strong similarity to benign bone tumors they are frequently misdiagnosed as such. The correct diagnosis followed by radical surgery, however, is essential to reduce the high risk of local recurrences, typically seen for of these lesions. Unlike conventional high grade osteosarcomas, distant metastases are much less frequent than in low grade osteosarcomas.     

Altered cell-mediated immunity and increased postoperative infection rate in long-term alcoholic patients

BACKGROUND: Preoperative alteration of T cell-mediated immunity as well as an altered immune response to surgical stress were found in long-term alcoholic patients. The aim of this study was to evaluate perioperative T cell-mediated immune parameters as well as cytokine release from whole blood cells after lipopolysaccharide stimulation and its association with postoperative infections. METHODS: Fifty-four patients undergoing elective surgery of the aerodigestive tract were included in this prospective observational study. Long-term alcoholic patients (n = 31) were defined as having a daily ethanol consumption of at least 60 g and fulfilling the Diagnostic and Statistical Manual of Mental Disorders for either alcohol abuse or alcohol dependence. The nonalcoholic patients (n = 23) were defined as drinking less than 60 g ethanol/day. Blood samples to analyze the immune status were obtained on morning before surgery and on the morning of days 1, 3, and 5 after surgery. RESULTS: Basic patient characteristics did not differ between groups. Before surgery, the T helper 1:T helper 2 ratio (Th1: Th2) was significantly lower (P < 0.01), whereas plasma interleukin 1beta and lipopolysaccharide-stimulated interleukin 1ra from whole blood cells were increased in long-term alcoholic patients. After surgery, a significant suppression of the cytotoxic lymphocyte ratio (Tc1:Tc2), the interferon gamma:interleukin 10 ratio from lipopolysaccharide-stimulated whole blood cells, and a significant increase of plasma interleukin 10 was observed. Long-term alcoholics had more frequent postoperative infections compared with nonalcoholic patients (54%vs. 26%; P = 0.03). CONCLUSIONS: T helper cell-mediated immunity was significantly suppressed before surgery and possibly led to inadequate cytotoxic lymphocyte and whole blood cell response in long-term alcoholic patients after surgery. This altered cell-mediated immunity might have accounted for the increased infection rate in long-term alcoholic patients after surgery.     

Noninvasive in vivo analysis of the human hepatic microcirculation using orthogonal polorization spectral imaging

BACKGROUND: Analysis of hepatic microvascular perfusion in humans by direct imaging has been impossible so far. Orthogonal polarization spectral (OPS) imaging represents a new technology that combines simultaneous epi-illumination of the subject with linearly polarized light and noninvasive imaging of the microcirculation by reflectance spectrophotometry. The aim of this study was to evaluate the feasibility of studying the human hepatic microcirculation by OPS imaging in vivo and to define microcirculatory parameters for physiologic conditions. METHODS: The hepatic microcirculation was analyzed in four different regions of both liver lobes in 11 healthy individuals undergoing partial liver resection for living-donor liver transplantation. The optical probe was gently positioned on the liver surface and sequences of at least 20 sec per measurement were recorded by a charge-coupled device camera on videotape. Microhemodynamic parameters were quantified off-line by single-frame and frame-to-frame analysis using a computer-assisted image analysis system. RESULTS: OPS images of the hepatic microcirculation showed an acceptable quality with good resolution. Quantitative analysis revealed a sinusoidal red blood cell velocity of 0.97+/-0.43 mm/sec, a sinusoidal diameter of 8.8+/-0.9 microm, a sinusoidal volumetric blood flow of 58.2+/-9.6 pL/sec, an intersinusoidal distance of 22.6+/-2.5 microm, and a mean functional sinusoidal density of 391+/-30 cm-1. Apart from the sinusoidal red blood cell velocity, all data of the parameters studied matched the pattern of normal distribution. CONCLUSIONS: OPS imaging enabled for the first time direct in vivo visualization and quantification of the human hepatic microcirculation, providing significant insight into microvascular physiology of the human liver, to the extent that these data can be considered to represent physiologic values for human hepatic microcirculation.     

Preoperative oral carbohydrate administration to ASA III-IV patients undergoing elective cardiac surgery

In this study we investigated the effects of preoperative oral carbohydrate administration on postoperative insulin resistance (PIR), gastric fluid volume, preoperative discomfort, and variables of organ dysfunction in ASA physical status III-IV patients undergoing elective cardiac surgery, including those with noninsulin-dependent Type-2 diabetes mellitus. Before surgery, 188 patients were randomized to receive a clear 12.5% carbohydrate drink (CHO), flavored water (placebo), or to fast overnight (control). CHO and placebo were treated in double-blind format and received 800 mL of the corresponding beverage in the evening and 400 mL 2 h before surgery. Patients were monitored from induction of general anesthesia until 24 h postoperatively. Exogenous insulin requirements to control blood glucose levels 相似文献   

The effect of computerized tailored brief advice on at-risk drinking in subcritically injured trauma patients

BACKGROUND: One-third of injured patients treated in the emergency department (ED) have an alcohol use disorder (AUD). Few are screened and receive counseling because ED staff have little time for additional tasks. We hypothesized that computer technology can screen and provide an intervention that reduces at-risk drinking (British Medical Association criteria) in injured ED patients. METHODS: In all, 3,026 subcritically injured patients admitted to an ED were screened for an AUD using a laptop computer that administered the AUD Identification Test (AUDIT) and assessed motivation to reduce drinking. Patients with a positive AUDIT (n = 1,139) were randomized to an intervention (n = 563) or control (n = 576) condition. The computer generated a customized printout based on the patient's own alcohol use pattern, level of motivation, and personal factors, which was provided in the form of feedback and advice. RESULTS: Most patients (85%) used the computer with minimal assistance. At study entry, a similar proportion in each group met criteria for at-risk drinking (49.6% versus 46.8%, p = 0.355). At 6 months, 21.7% of intervention and 30.4% of control patients met criteria for at-risk drinking (p = 0.008). Intervention patients also had a 35.7% decrease in alcohol intake, compared with a 20.5% decrease in controls (p = 0.006). At 12 months, alcohol intake decreased by 22.8% in the intervention group versus 10.9% in controls (p = 0.023), but the proportion of at-risk drinkers did not significantly differ (37.3% versus 42.6%, p = 0.168). CONCLUSIONS: The computer-generated intervention was associated with a significant decrease in alcohol use and at-risk drinking. Research is needed to further evaluate and adapt information technology to provide preventive clinical services in the ED.     

Giant cell tumors of the bone: molecular profiling and expression analysis of Ephrin A1 receptor, Claudin 7, CD52, FGFR3 and AMFR

Giant cell tumors (GCTs) of the bone are osteolytic neoplasms with variable degrees of aggressiveness. The aim of this study was the molecular characterization of GCT tissue. We established gene expression profiles and discovered a number of genes that have not been described in GCTs before. RNA was prepared from 7 cryopreserved GCTs (primary tumors n = 5, relapses n = 2) and was hybridized to Affymetrix HG U133A microarrays. Paraffin-embedded samples were used for immunohistochemical validation (primary tumors n = 16, relapses n = 6). Gene ontology revealed that the majority of genes, found to be differentially expressed between primary and recurrent GCTs, were associated with receptor tyrosine kinase activity. We selected one upregulated gene (Claudin 7) and four downregulated genes (CD52, Ephrin A1 receptor, autocrine motility factor receptor [AMFR] and fibroblast growth factor receptor 3 [FGFR3] for further analysis using immunohistochemistry. Immunohistochemical analysis of CD52, AMFR, and Ephrin A1 receptor revealed expression profiles concordant with the microarray data, also with regard to differences between primary tumors and relapses.

Minimally invasive combined anterior kyphoplasty for osteolytic C2 and C5 metastases

Kypho- and vertebroplasty are widely accepted for treating patients suffering from pathologic thoracolumbar lesions, in particular diffuse metastatic-induced fractures. They provide rapid pain relief and the restoration of spinal stability. In the cervical spine, attempts have been made to use cement augmentation for these indications. However, the cervical spine’s anatomy complicates the transpedicular approach, as well as the pre-formation of a vertebral body cavity and the application of bone cement. We report the case of a 46-year-old woman suffering from symptomatic C2 and C5 osteolysis caused by metastatic breast cancer. Following a surgical staging and classification (Tokuhashi-Score) that indicated palliative procedures, we performed a C2 and C5 kyphoplasty using one minimal-invasive anterior approach through a small incision. We observed an uneventful procedure and postoperative course as well as immediate pain relief and patient mobilization. Last patient follow-up at 3 months showed an excellent outcome. Our observations showed cervical spine kyphoplasty via a minimally invasive anterior approach to be feasible, successful and safe surgical method in the interdisciplinary palliative treatment.     

Biochemistry of the Anterior, Medial, and Posterior Genioglossus in the Aged Rat

Age-related tongue weakness may contribute to swallowing deficits in the elderly. One contributing factor may be an alteration in muscle-fiber-type properties with aging. However, it is not clear how muscle fiber types within the aged tongue may vary from those found in young adults, or how fiber types may vary across the anteroposterior axis of the extrinsic tongue muscles. We examined the myosin heavy chain (MHC) composition of anterior, medial, and posterior sections of the genioglossus muscle (GG) in ten old male Fischer 344/Brown Norway rats and compared findings to previously reported data from young adult male rats. Significant differences (p < 0.01) between young adult and old rats were found in the distribution of MHC isoforms along the anteroposterior axis of the muscle. In the anterior, medial, and posterior regions, there was a significantly smaller proportion of type IIb MHC in the old rat GG muscles, while the proportion of type IIx MHC was significantly greater. In the medial region, the proportion of type I MHC was found to be significantly greater in the old rats. Thus, we found a shift to more slowly contracting muscle fibers in the aged rat tongue.
