The Relationship Between Yoga Practice Dosage and Perceived Stress, Anxiety, and Self-reported Health Among Breast Cancer Survivors Who Practice Yoga.

The aim of this anonymous online study was to explore the yoga practice of breast cancer survivors to determine if yoga dosage (frequency and duration of practice) was related to stress, anxiety, and self-reported health in female survivors. Participants were recruited from online breast cancer support groups during a 3-month period (June-September 2019). Demographic information, stage and treatment of breast cancer, and frequency of yoga participation, including a home yoga practice were reported. Measures include the Perceived Stress Scale, State-Trait Anxiety Inventory, and self-reported health. Cumulative yoga dosage was calculated. Thirty-five women participated (mean age = 55 years) and were divided into low and high yoga dosage groups based on the sample distribution. Low dosage of yoga was operationally defined as a cumulative dosage that fell within the lowest quartile (≤25%). Findings indicated no difference between the low-dosage group compared with the high-dosage group for perceived stress and self-reported health; but the high dosage yoga group had lower state anxiety scores (P < .05). All participants reported good self-reported health. These findings contribute to our knowledge of the psychosocial aspects of breast cancer survivorship and raise questions for further research quantifying the therapeutic dosing of yoga practice.

Lying Down after Premature Rupture of the Membranes in Term Singleton Pregnancies: An Evidence-Based Recommendation?

Objectives: In many countries pregnant women in term singleton pregnancies are advised by obstetricians and midwives to lie down immediately after rupture of membranes until engagement of the foetal head is confirmed. The horizontal positioning aims to prevent the prolapse of the umbilical cord. The objective of this systematic review is to assess the effects of the maternal lying down measure in term singleton pregnancies. Search methods: We searched the databases of MEDLINE/PubMed, EMBASE/Ovid and CENTRAL (Issue 10, 2015) from their inception until September 30th, 2015. Additionally, we searched selected trial registers, the reference lists of potentially relevant studies and national and international obstetrical clinical guidelines. All types of studies without language restriction were selected. Main results: One retrospective study was found. Only one woman with a term singleton pregnancy had the event of an umbilical cord prolapse following premature rupture of membranes (0.008%). The study did not report on the presence of an engaged foetal head in this woman. Conclusions and implications: Recommendations cannot be made in favour or against the lying down positioning based solely on the single identified study. For that reason, the widespread recommendation given by obstetricians and midwives should be critically reassessed. Also, induction of maternal anxiety and increased costs to the healthcare system following transportation to the delivery unit have to be considered in the light of the given minimal risk of umbilical cord prolapse in conjuncture with lacking evidence for the utility of the common recommendation.

The Direct Assessment of Nonvertebral Fractures in Community Experience (DANCE) study: 2-year nonvertebral fragility fracture results.

UNLABELLED: This observational study evaluated the occurrence of nonvertebral fragility fractures (NVFX) in over 4,000 men and women with osteoporosis treated with teriparatide (TPTD). The incidence of new NVFX decreased for patients receiving TPTD treatment for greater than 6 months. No new significant safety findings were observed in this large trial. INTRODUCTION: The Direct Assessment of Nonvertebral Fractures in Community Experience (DANCE) study evaluated the occurrence of NVFX in patients receiving TPTD for osteoporosis in a real-world setting. METHODS: DANCE is a multicenter, prospective, observational trial that examined the long-term effectiveness of TPTD in men and women with osteoporosis whom study physicians judged to be suitable for TPTD therapy. Patients received 20 µg TPTD per day by subcutaneous injection for up to 24 months and were followed for 24 months after treatment cessation. The incidence of patients experiencing a new NVFX, defined as a fracture associated with low trauma, was evaluated during four 6-month periods in both the treatment and cessation phases with >0 to ≤6 months serving as the reference. We also observed the spectrum and occurrence of serious adverse events. RESULTS: Of the 4,167 patients enrolled, 4,085 took one or more doses of TPTD (safety population); 3,720 were included in the efficacy analysis. The incidence of patients experiencing a NVFX was 1.42, 0.91, 0.70, and 0.81 % for the four treatment periods, respectively, and 0.80, 0.68, 0.33, and 0.33 % for the four periods after treatment cessation. Differences for each period were statistically significant compared with the reference period (first 6-month interval, each p < 0.05). No new significant safety findings were observed. CONCLUSIONS: In this study, the incidence of NVFX decreased for patients receiving TPTD for all three treatment periods >6 months compared to 0 to ≤6 months, and this trend persisted throughout the cessation phase. TPTD was generally well tolerated.

The journey of women with breast cancer who engage in mindfulness-based stress reduction: a qualitative exploration.

This phenomenological study explores the "lived experience" of 8 women with stage I or II breast cancer who used mindfulness-based stress reduction (MBSR). The following 4 themes were identified: (1) the cancer journey: a shift in perception, (2) the treatment journey: the experience of MBSR, (3) the journey toward recovery, and (4) the journey toward self.

Causes of chronic vaginitis: analysis of a prospective database of affected women.

OBJECTIVE: To compare women with different chronic vaginal symptoms with a wide variety of sociodemographic, health, behavioral, and psychosocial characteristics. METHODS: Serially recruited subjects answered a questionnaire that asks about demographic information and symptoms and measures depression and stress scores. Patients underwent a standardized history, physical examination, and laboratory examination. Patients with recurrent vulvovaginal candidiasis, vulvar vestibulitis syndrome, desquamative inflammatory vaginitis, physiologic leukorrhea, and other diagnoses were compared with one another. Chi-square tests and one-way analysis of variance with Tukey honestly significant difference (HSD) post hoc analyses were used for categorical and continuous data analysis. RESULTS: Two hundred patients were enrolled in this study. The most common diagnoses were contact dermatitis (21%), recurrent vulvovaginal candidiasis (20.5%), atrophic vaginitis (14.5%), and vulvar vestibulitis syndrome (12.5%); 18% of women had 2 or more diagnoses. In the overall study sample, the mean age was 38.4 years, 78% were white, and 55% were college educated. Sixty-two percent had symptoms for over a year. Desquamative inflammatory vaginitis patients were older and less likely to be menstruating. Those with vulvar vestibulitis syndrome had more frequent complaints of dyspareunia. Recurrent vulvovaginal candidiasis patients felt that their symptoms had the greatest negative impact on work and social life. There were high rates of psychiatric disorder (43.5%), atopic disease (42.5%), and pain syndrome (56%) in all groups. CONCLUSION: Women with chronic vaginal symptoms have a variety of diagnoses, most of them noninfectious. LEVEL OF EVIDENCE: II-3.

Vaginal Candida parapsilosis: pathogen or bystander?

OBJECTIVE: Candida parapsilosis is an infrequent isolate on vaginal cultures; its role as a vaginal pathogen remains unstudied. This retrospective study of women with positive culture for C. parapsilosis sought to characterize the significance of this finding and its response to antifungal therapy. METHODS: From February 2001 to August 2002, we identified all individuals with positive fungal isolates among a population of women with chronic vulvovaginal symptoms. Charts of women with C. parapsilosis cultures were reviewed with regard to patient demographics, clinical presentation and therapeutic response. Mycological cure, defined as a negative fungal culture at the next office visit, and clinical cure, i.e. symptom resolution, were determined for each subject. RESULTS: A total of 582 women had positive vaginal cultures for 635 isolates, of which 54 (8.5%) were C. parapsilosis. The charts of 51 subjects with C. parapsilosis were available for review and follow-up cultures and clinical information were available for 39 (76.5%). Microscopy was positive in 9 (17.6%). Antifungal treatment resulted in mycological cure in 17/19 patients with fluconazole, 7/7 with butoconazole, 6/6 with boric acid, 1/1 with miconazole and occurred spontaneously in 6/7: 24/37 (64.9%) patients with a mycological cure experienced clinical cure. CONCLUSIONS: Although C. parapsilosis is often a cause of vaginal symptoms, it seems to respond to a variety of antifungal agents and may even be a transient vaginal colonizer.

Treatment of recurrent bacterial vaginosis with tinidazole.

BACKGROUND: Recurrent bacterial vaginosis is a difficult clinical condition. In women with recurrent bacterial vaginosis, relapses are common, even after prolonged courses of maintenance therapy. Because of its spectrum of activity, tinidazole was used in a patient with recurrent bacterial vaginosis. CASE: A 23-year-old woman taking oral contraceptives had a single sexual partner. She was treated for recurrent bacterial vaginosis with multiple courses of metronidazole gel 0.75%, including regimens of maintenance therapy. The patient experienced repeated recurrences shortly after stopping treatment. A single course of oral tinidazole resulted in a prolonged period where she was free of bacterial vaginosis. CONCLUSION: Treatment options for recurrent bacterial vaginosis are currently limited. Tinidazole may be a useful option in women with recurrent bacterial vaginosis.

Risk factors for recurrent vulvovaginal candidiasis in women receiving maintenance antifungal therapy: results of a prospective cohort study.

OBJECTIVE: The purpose of this study was to examine risk factors for symptomatic vulvovaginal candidiasis episodes among women with recurrent vulvovaginal candidiasis (defined as >/=4 vulvovaginal candidiasis episodes in 1 year) who were receiving maintenance antifungal therapy. STUDY DESIGN: A prospective study of 65 women aged >/=18 years with recurrent vulvovaginal candidiasis who attended vaginitis clinics in Detroit, Mich, and Philadelphia, Pa. RESULTS: The 9-month risk of vulvovaginal candidiasis recurrence was 41.8%. Almost two fifths of the women reported activity limitations because of vulvovaginal candidiasis episodes, most or all of the time. Younger women and those women with a history of bacterial vaginosis were at increased risk of vulvovaginal candidiasis episodes. Behavioral factors that were associated significantly with increasing vulvovaginal candidiasis recurrence >/=2- fold included wearing pantyliners or pantyhose and consuming cranberry juice or acidophilus-containing products. CONCLUSION: The use of pantyliners or pantyhose, consumption of cranberry juice or acidophil-containing products, a history of bacterial vaginosis, and age <40 years were positively associated with a symptomatic vulvovaginal candidiasis episode.

Subclinical activation of latent cytomegalovirus (CMV) infection and anti-CMV immune response in patients with atopic dermatitis.

BACKGROUND: Microbiological infections are considered to be of pathophysiological importance in atopic dermatitis (AD). As yet, no information is available regarding cytomegalovirus (CMV) infection in this disease. This, however, is of interest because of the high prevalence of latent infections in the general population, the frequent reactivation in inflammatory diseases, and the immunomodulating capacity of CMV. OBJECTIVES: To investigate the prevalence of latent CMV infection, the frequency of active CMV infection, and the immune response to CMV in patients with moderate to severe AD. Methods To detect active infection we analysed CMV antigen expression by peripheral blood mononuclear cells (PBMC) from 27 patients with moderate to severe AD in comparison with 53 healthy volunteers. We used three monoclonal antibodies recognizing different CMV-encoded antigens and immunocytological staining (alkaline phosphatase-antialkaline phosphatase technique). RESULTS: Patients with AD had a higher mean frequency of CMV-positive PBMC: 2.25 per 10 000 vs. 0.74 per 10 000 in controls (P = 0.001) as well as a higher incidence of CMV antigenaemia: 29.6% vs. 7.5% (P < 0.01). Seropositivity for anti-CMV IgG antibodies indicated subclinical activation of latent infection. Remarkably, a clearance of CMV antigenaemia was observed during anti-eczematous treatment. Significantly higher plasma levels of tumour necrosis factor-alpha, which is involved in CMV reactivation, and interleukin-12, which is crucial for an antiviral cellular immune response, were observed in AD patients in comparison with healthy volunteers. Furthermore, a significantly enhanced frequency of circulating activated HLA-DR+ T cells especially in CMV-seropositive AD patients (19.3% vs. 13.5% in seronegative AD patients vs. 10.2% in controls) suggested that the active CMV infection triggers a cellular immune response. This was also supported by a high frequency of CMV-specific interferon-gamma-producing T cells in CMV-seropositive patients with AD. CONCLUSIONS: Our data suggest that active, subclinical CMV infection is more frequent in patients with moderate to severe AD and may have immunopathophysiological relevance.

Superresolution of pulsed multiphoton Raman transitions.

We have investigated higher order multiphoton Raman resonances with two pulsed optical frequencies. Multiphoton transfer with up to 50 photons is observed with milliwatts of laser power. We demonstrate that the spectral width of the multiphoton resonances can be far below the Fourier transform linewidth of the driving optical pulses. The functional dependence of the transition linewidth on the number of exchanged photons is found to vary with the pulse shape. Our experiment is performed with laser-cooled rubidium atoms confined in a CO2-laser optical dipole trap.

Controlled decoherence in multiple beam Ramsey interference.

We have scattered photons from an interfering path of a multiple beam Ramsey interference experiment realized with a cesium atomic beam. It is demonstrated that in multiple beam interference the decoherence from photon scattering cannot only lead to a decrease but, under certain conditions, also to an increase of the Michelson fringe contrast. In all cases, the atomic quantum state loses information with photon scattering, as "which-path" information is carried away by the photon field. We outline an approach to quantify this which-path information from observed fringe signals, which allows for an appropriate measure of decoherence in multiple path interference.

Cromolyn cream for recalcitrant idiopathic vulvar vestibulitis: results of a placebo controlled study.

OBJECTIVE: Patients with chronic idiopathic vulvar vestibulitis have increased mast cells when biopsied, and cromolyn has been suggested as a treatment. The purpose of this study was to assess the efficacy of 4% cromolyn cream in women with vulvar vestibulitis. METHODS: A prospective, double blind, randomised, placebo controlled study was initiated at two centres. Patients with vulvar vestibulitis were assigned to apply cromolyn or placebo cream to the vestibule. Symptoms (burning, irritation) and signs (erythema, extent of erythema, tenderness) were recorded on a 0-3 scale. In the sexually active patient subgroup, dyspareunia was also evaluated. RESULTS: 13 of the 26 evaluable patients received cromolyn. Patients in the cromolyn arm were more likely to have failed therapy with amitriptyline (p = 0.05), but the two groups were otherwise similar upon study entry. Overall, scores decreased from a median of 9 to 5 (p = 0.001) during the study, but the level of improvement was similar between both groups. Improvement was unrelated to duration of symptoms, fluconazole use, or sexual activity. Five patients (38%) taking cromolyn and six (46%) taking placebo felt they had a 50% or greater reduction in symptoms. In the 21 sexually active patients, the total score decreased from a mean of 12 to 8 (p = 0.005), but there was no statistically significant difference between study arms. CONCLUSIONS: Cromolyn cream did not confer a significant benefit in patients with vulvar vestibulitis. The large placebo response suggests the need for large well controlled studies of other treatment modalities.

Phase coherent vacuum-ultraviolet to radio frequency comparison with a mode-locked laser

We demonstrate a versatile new technique that provides a phase coherent link between optical frequencies and the radio frequency domain. The regularly spaced comb of modes of a mode-locked femtosecond laser is used as a precise ruler to measure a large frequency gap between two different multiples (harmonics or subharmonics) of a laser frequency. In this way, we have determined a new value of the hydrogen 1S-2S two-photon resonance, f(1S-2S) = 2 466 061 413 187.29(37) kHz, representing now the most accurate measurement of an optical frequency.

Measurement of the hydrogen 1S- 2S transition frequency by phase coherent comparison with a microwave cesium fountain clock

We report on an absolute frequency measurement of the hydrogen 1S-2S two-photon transition in a cold atomic beam with an accuracy of 1.8 parts in 10(14). Our experimental result of 2 466 061 413 187 103(46) Hz has been obtained by phase coherent comparison of the hydrogen transition frequency with an atomic cesium fountain clock. Both frequencies are linked with a comb of laser frequencies emitted by a mode locked laser.

Pancreatic cancer detection with magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography: a prospective controlled study.

BACKGROUND: Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive and increasingly used procedure in cases involving biliary and pancreatic diseases. However, the accuracy of MRCP in differential diagnosis between pancreatic cancer and chronic pancreatitis has never been documented in a large prospective controlled study. METHODS: 124 patients were recruited for the study, selected from 141 consecutive patients with an average age of 55 years (range 19-80) who presented to our department between February, 1996, and January, 1998, with a strong clinical suspicion of pancreatic cancer. MRCP images were interpreted by a radiologist and a gastroenterologist who were unaware of the clinical diagnosis of patients. The exact diagnosis was based upon histological evidence from biopsy examination (surgical and fine needle biopsy) or a follow-up of at least 12 months. FINDINGS: Of the 124 patients, 37 (30%) had pancreatic carcinoma; 17 (14%) had other neoplastic pancreatic diseases; 57 (46%) had chronic pancreatitis; 13 (10%) pancreatic ducts were clear. The sensitivity of MRCP with respect to diagnosing pancreatic cancer was 84% and its specificity 97%. The corresponding values for endoscopic retrograde cholangiopancreatography (ERCP) were 70% and 94%, respectively. INTERPRETATION: MRCP is as sensitive as ERCP when detecting pancreatic carcinomas. Furthermore, it is feasible to presume that the use of MRCP may prevent inappropriate explorations of the pancreatic and common bileducts in cases of suspected pancreatic carcinomas, where interventional endoscopic therapy (ie, palliative common-bileduct drainage) is unlikely.

Multiple endocrine neoplasia type 1 (MEN1) gene mutations in a subset of patients with sporadic and familial primary hyperparathyroidism target the coding sequence but spare the promoter region.

Germ line mutations of the multiple endocrine neoplasia type 1 (MEN1) tumour suppressor gene cause MEN1, a rare familial tumour syndrome associated with parathyroid hyperplasia, adenoma and hyperparathyroidism (HP). Here we investigated the role of the MEN1 gene in isolated sporadic and familial HP. Using RT-PCR single-strand conformational polymorphism screening, somatic (but not germ line) mutations of the MEN1 coding sequence were identified in 6 of 31 (19.3%) adenomas from patients with sporadic primary HP, but none in patients (n=16) with secondary HP due to chronic renal failure. MEN1 mutations were accompanied by a loss of heterozygosity (LOH) for the MEN1 locus on chromosome 11q13 in the adenomas as detected by microsatellite analysis. No DNA sequence divergence within the 5' region of the MEN1 gene, containing the putative MEN1 promoter, was detectable in HP adenomas. Clinical characteristics were not different in HP patients with or without MEN1 mutation. Heterozygous MEN1 gene polymorphisms were identified in 9.6% and 25% of patients with primary and secondary HP respectively. In a large kindred with familial isolated familial HP, MEN1 germ line mutation 249 del4 and LOH was associated with the HP phenotype and a predisposition to non-endocrine malignancies. We suggest that the bi-allelic somatic loss of MEN1 wild-type gene expression is involved in the pathogenesis of a clinically yet undefined subset of sporadic primary HP adenomas. MEN1 genotyping may further help define the familial hyperparathyroidism-MEN1 disease complex, but it seems dispensable in sporadic primary HP.

Choledochocele imaged with magnetic resonance cholangiography.

Choledochal cysts are rare developmental malformations of the biliary tree. Percutaneous and endoscopic ultrasound, as well as endoscopic retrograde cholangiopancreatography, are recommended diagnostic tools. Magnetic resonance cholangiography may also contribute to the workup and treatment plan of patients with choledochal cysts. We report a 25-yr-old white woman with episodic nausea and moderate epigastric discomfort. Magnetic resonance cholangiography showed a rather spherical, cyst-like, fluid-filled structure in continuity with the prepapillary segment of the common bile duct, thus making a choledochocele (type III choledochal cyst) likely. The patient was treated by endoscopic sphincterotomy and, after a 6-month follow-up, is without complaints.

Terconazole cream for non-Candida albicans fungal vaginitis: results of a retrospective analysis.

OBJECTIVE: Although it is FDA-approved for use in vulvovaginal candidiasis caused by non-Candida albicans species, terconazole cream has not been been studied in patients with these infections. We sought to assess the clinical and mycological efficacy of terconazole cream in women with non-C. albicans vaginitis. METHODS: The records of patients who had received a 7-day course of terconazole cream for culture-proved non-C. albicans vaginitis were reviewed. Data with regard to patient demographics, clinical and mycologic response to therapy within 1 month of treatment, and outcome with other antifungal therapies were analyzed. RESULTS: Twenty-eight patients received terconazole cream for non-C. albicans infections. Three patients did not return for follow-up. The median age was 45 years. Seven (28%) patients were nulliparous. The median duration of symptoms was 3 years. Nine patients (36%) had received terconazole within the 6 months prior to referral. Overall, there were 20 C. glabrata cases, 3 C. parapsilosis, and 2 C. lusitaniae. Fourteen (56%) patients achieved a mycologic cure; 11 (44%) noted a resolution of their symptoms. Prior terconazole use was not associated with treatment failure (P = 0.09). Ten failures received boric acid suppositories as subsequent treatment; a cure was effected in 4 (40%). Two of three patients (67%) were eventually cured with flucytosine cream. Five (20 %) patients remained uncured. CONCLUSIONS: Terconazole cream may be an appropriate first-line treatment for non C. albicans vaginitis, even in patients who have previously received the drug.

A prospective evaluation of magnetic resonance cholangiopancreatography in patients with suspected bile duct obstruction.

BACKGROUND: The value of magnetic resonance cholangiopancreatography (MRCP) is under debate. AIMS: To assess the diagnostic accuracy of MRCP and endoscopic retrograde cholangiopancreatography (ERCP) and to determine whether MRCP may help to prevent unnecessary interventional procedures. METHODS: Eighty six patients with suspected common bile duct obstruction who presented between January and December 1996 were enrolled. Twenty six were excluded due to anatomical reasons or because MRCP or ERCP could not be performed successfully. Results of MRCP were interpreted by two radiologists and a gastroenterologist unaware of clinical diagnosis. Final diagnosis was determined by ERCP and histopathological findings or a follow up of at least 12 months. RESULTS: MRCP images of diagnostic quality were obtained in all 60 patients. Thirteen patients had a clear bile duct. Sensitivity and specificity for the detection of any abnormality (n=47) were 89% and 92%, and for the detection of malignancy (n=27) 81% and 100%, respectively. These results were equivalent to the respective figures of ERCP (91% and 92% for any abnormality, and 93% and 94% for malignant diseases). CONCLUSIONS: MRCP is as sensitive as ERCP in the evaluation of bilary tract diseases. As the specificity of this non-invasive technique is close to 100%, MRCP may prevent inappropriate invasive explorations of the common bile duct and pancreatic duct.
