Sexual activity and function in women with and without pelvic floor disorders

Introduction and hypothesis

We describe differences in sexual activity and function in women with and without pelvic floor disorders (PFDs).

Methods

Heterosexual women ≥40 years of age who presented to either urogynecology or general gynecology clinics at 11 clinical sites were recruited. Women were asked if they were sexually active with a male partner. Validated questionnaires and Pelvic Organ Prolapse Quantification (POP-Q) examinations assessed urinary incontinence (UI), fecal incontinence (FI), and/or pelvic organ prolapse (POP). Sexual activity and function was measured by the Female Sexual Function Index (FSFI). Student’s t test was used to assess continuous variables; categorical variables were assessed with Fisher’s exact test and logistic regression. Univariate and multivariate analyses were used to assess the impact of pelvic floor disorders (PFDs) on FSFI total and domain scores.

Results

Five hundred and five women met eligibility requirements and gave consent for participation. Women with and without PFDs did not differ in race, body mass index (BMI), comorbid medical conditions, or hormone use. Women with PFDs were slightly older than women without PFDs (55.6?+?10.8 vs. 51.6?+?8.3 years, P <0.001); all analyses were controlled for age. Women with PFDs were as likely to be sexually active as women without PFDs (61.6 vs. 75.5 %, P?=?0.09). There was no difference in total FSFI scores between cohorts (23.2?+?8.5 vs. 24.4?+?9.2, P?=?0.23) or FSFI domain scores (all P?=?NS).

Conclusion

Rates of sexual activity and function are not different between women with and without PFDs.     

The astrocyte in multiple sclerosis revisited

Among the constituent cell types of the multiple sclerosis (MS) plaque, the astrocyte has been the least considered as a player in the pathogenesis of the lesion. Traditionally, it has been assigned a secondary scarring role with little or no role in lesion formation or repair. However, the recent upsurge of interest in the demyelinating condition neuromyelitis optica (NMO) has resulted in NMO being identified as the first disease of myelin in which primary damage to astrocytes, resulting from a humoral immune response that forms against the water channel aquaporin‐4, has been documented. This finding in NMO prompted us to re‐examine data and material from cases of MS displaying active lesions. Our reappraisal revealed unambiguous early damage to perivascular astrocyte end‐feet and to hypertrophic astrocytes in the adjacent parenchyma, but whether this was a primary event was difficult to evaluate due to concomitant edema and inflammation in these acute lesions. The astrocyte damage was long‐lasting since resolving lesions displaying remyelination also showed defects in the integrity of the astrocytic covering around blood vessels. Analysis of our findings and of the astrocytic literature supports multiple roles for the astrocyte in the evolution of changes encountered in MS depending upon lesion stage and lesion topography. At variance with the somewhat inhibitory role of the astrocyte is the abundant and growing evidence for this cell to actively participate in both lesion development and repair. We propose that the unequivocal selective early involvement of the astrocyte in MS lesions may have therapeutic relevance. © 2013 Wiley Periodicals, Inc.     

Transcatheter aortic valve replacement (TAVR) as bridge therapy restoring eligibility for liver transplantation in cirrhotic patients

Severe aortic stenosis is a widespread valve disease, constituting a contraindication to organ transplantation due to cardiovascular morbidity and projected mortality. Mortality after conventional surgical aortic valve replacement in cirrhotic patients depends upon the Child–Pugh class. In the past few years, transcatheter aortic valve replacement has progressively become the treatment of choice for high‐risk patients with severe aortic stenosis. Here, we report the cases of 3 cirrhotic patients who became eligible for liver transplantation after successful transcatheter aortic valve replacement as bridge therapy.     

Comparison of 18FDG-PET/CT and conventional follow-up methods in colorectal cancer: A randomised prospective study

BackgroundA surveillance program was performed in colorectal cancer (CRC) patients after surgery, to diagnose asymptomatic recurrence.AimsTo assess whether 18-FDG positron emission tomography/CT (PET/CT) improved the detection of recurrence during a 3-year follow-up.MethodsA multicentre, two-arm randomised prospective trial comparing different 36-month follow-up strategies. Complete colonoscopy was performed at baseline and after 3 years and clinical exams with imaging every 3 months. The conventional arm (A) received carcinoembryonic antigen, liver echography, and alternated between lung radiography and computed tomography (CT) scans. The experimental arm (B) received PET/CT.ResultsA total of 365 patients with colon (79.4%) or rectal cancer (20.6%), stages II (48.2%) or III (50.8%), were enroled in this study. At 36 months, intention-to-treat analysis revealed recurrence in 31 (17.2%) patients in arm A and 47 (25.4%) in arm B (p = 0.063). At 3 years, 7 of 31 relapses (22.5%) in arm A were surgically treated with curative intent, compared to 17 of 47 (36.2%) in arm B (p = 0.25). The rates of recurrence and new cancers were higher in arm B than arm A (p = 0.038).ConclusionsPET/CT follow-up every 6 months did not increase the rate of recurrence at 3 years or the rate of surgically treated recurrence compared with conventional follow-up.     

Trends and occupational associations in incidence of hospitalized pulmonary sarcoidosis and other lung diseases in Navy personnel: a 27-year historical prospective study, 1975-2001

STUDY OBJECTIVES: This study examines long-term trends in incidence rates of hospitalized pulmonary sarcoidosis in a large cohort of Navy personnel, and evaluates the possible relationship of sarcoidosis with occupation. DESIGN: Incidence rates of first hospitalizations were determined for black and white male Navy enlisted personnel on active duty from 1975 to 2001. SETTING: Navy service includes a potential for exposure to a variety of substances, including nonskid coatings used on ship decks that may be aerosolized during removal. Particulate matter containing aluminum, titanium, and silicates has been identified in nonskid samples. Specific occupational groups may have had greater exposure potential than others. PATIENTS OR PARTICIPANTS: Hospitalized cases included sarcoidosis (n = 674), asthma (n = 3,536), emphysema and chronic bronchitis (n = 1,103), respiratory conditions due to fumes and vapors (n = 61), and pneumoconiosis (n = 51) observed in 9,953,607 person-years of active-duty service. INTERVENTIONS: None. However, improvements were made in personal protective gear and other countermeasures to prevent or limit respiratory exposures during service. MEASUREMENTS AND RESULTS: Annual overall hospitalized sarcoidosis incidence rates per 100,000 were 24.9 for black men and 3.5 for white men (black/white ratio of 7.1, p < 0.0001). Annual incidence rates in blacks declined markedly, particularly since 1989, but the black/white ratio remained high through 1999. Occupational associations were present in blacks and whites. Black ship's servicemen (23 cases) and aviation structural mechanics specializing in structures (12 cases) had more than twice the expected incidence rate compared to all blacks, and white mess management specialists (15 cases) had twice the overall white incidence rate. CONCLUSIONS: There was a steep decline in incidence of hospitalized sarcoidosis in blacks in the Navy. Occupational associations suggest the possibility that a dust or moisture-related lung disease may have been erroneously classified as sarcoidosis, or, alternatively, that sarcoidosis had a previously unrecognized occupational component.     

Accuracy of multislice computed tomography in the preoperative assessment of coronary disease in patients with aortic valve stenosis.

OBJECTIVES: To evaluate multislice computed tomography (MSCT) as an alternative to coronary angiography, we prospectively studied its diagnostic accuracy for the detection of significant coronary artery lesions in patients with significant aortic valve stenosis undergoing valve surgery. BACKGROUND: In patients with aortic valve stenosis, coronary angiography is still recommended before surgery. Multislice computed tomography is a promising noninvasive technique for the detection of significant coronary artery lesions. METHODS: Fifty-five consecutive patients scheduled for coronary angiography in the preoperative assessment of aortic valve stenosis underwent 16-slice MSCT 24 h before coronary angiography. We analyzed coronary lesions, image quality, and arterial calcium score. RESULTS: The sensitivity of the MSCT-based strategy in detecting significant stenosis was 100%, and its specificity 80%. The positive and negative predictive values were respectively 55% and 100%. For calcium scores <1,000 (77% of patients), MSCT detected all patients without coronary artery disease, enabling conventional coronary angiography to be avoided in 35 of 55 cases (80%). For calcium scores >1,000, MSCT enabled conventional coronary angiography to be avoided in only 6% of cases, either because significant stenosis was found with a possible indication of revascularization, or because the examination was not interpretable. CONCLUSIONS: The results of this initial experience in relatively few patients suggest that MSCT-based coronary angiography may serve as an alternative to invasive coronary angiography to rule out significant coronary artery disease in patients scheduled for elective aortic valve replacement. Larger studies are necessary to fully explore the potential of coronary MSCT to improve preoperative risk stratification.     

25-Hydroxyvitamin D in the Range of 20 to 100 ng/mL and Incidence of Kidney Stones

Objectives. Increasing 25-hydroxyvitamin D serum levels can prevent a wide range of diseases. There is a concern about increasing kidney stone risk with vitamin D supplementation. We used GrassrootsHealth data to examine the relationship between vitamin D status and kidney stone incidence.Methods. The study included 2012 participants followed prospectively for a median of 19 months. Thirteen individuals self-reported kidney stones during the study period. Multivariate logistic regression was applied to assess the association between vitamin D status and kidney stones.Results. We found no statistically significant association between serum 25-hydroxyvitamin D and kidney stones (P = .42). Body mass index was significantly associated with kidney stone risk (odds ratio = 3.5; 95% confidence interval = 1.1, 11.3).Conclusions. We concluded that a serum 25-hydroxyvitamin D level of 20 to 100 nanograms per milliliter has no significant association with kidney stone incidence.An issue of possible concern related to the use of vitamin D supplementation is a reported increase in risk of kidney stones.1 Mounting evidence indicates that a 25-hydroxyvitamin D (25[OH]D) serum level in the range of 40 to 60 nanograms per milliliter (ng/mL) is needed for substantial reduction in risk of a wide range of diseases including breast cancer,2 colorectal cancer,3 multiple sclerosis,4 and type 1 diabetes.5,6 However, few people can achieve 25(OH)D in the range higher than 40 ng/mL without supplementation.7GrassrootsHealth is a nonprofit public health research organization that runs a large population cohort study of participants who reach and sustain, if desired, a 25(OH)D serum level of their choice and tracking subsequent health outcomes. GrassrootsHealth has assembled a database that includes information on serum 25(OH)D concentrations, demographic characteristics, and health status measures. These data include values from 5552 individuals with daily supplemental intakes averaging 3600 international units (IU) per day and an average 25(OH)D level of 45 ng/mL, which is higher than the ranges found in most other cohorts.2,4In this study we investigated whether serum 25(OH)D concentration in the range of 20 to 100 ng/mL was associated with incidence of kidney stones in all participants who provided data at 2 or more sampling times.
