Assessing Quality-of-Life of Patients Taking Mirabegron for Overactive Bladder.

Lower urinary tract symptoms (LUTS), including urgency, frequency, and urgency incontinence, are highly prevalent in the general population and increase in prevalence with increasing age. All LUTS, but notable urgency and urgency incontinence, are associated with negative impact on quality-of-life (QoL), with multiple aspects of QoL affected. Urgency and urgency incontinence are most commonly caused by overactive bladder (OAB), the clinical syndrome of urinary urgency, usually accompanied by increased daytime frequency and/or nocturia in the absence of infection or other obvious etiology, which may be treated with conservative and lifestyle interventions, bladder antimuscarinic drugs, and, more recently, by mirabegron, a ß3 agonist. This narrative review describes the impact of OAB on QoL, quantifies this impact, and outlines the evidence for the use of mirabegron in the treatment of, and improvement in QoL in, people with OAB.

Seagrass ecosystems of the Pacific Island Countries and Territories: A global bright spot.

Seagrass ecosystems exist throughout Pacific Island Countries and Territories (PICTs). Despite this area covering nearly 8% of the global ocean, information on seagrass distribution, biogeography, and status remains largely absent from the scientific literature. We confirm 16 seagrass species occur across 17 of the 22 PICTs with the highest number in Melanesia, followed by Micronesia and Polynesia respectively. The greatest diversity of seagrass occurs in Papua New Guinea (13 species), and attenuates eastward across the Pacific to two species in French Polynesia. We conservatively estimate seagrass extent to be 1446.2 km2, with the greatest extent (84%) in Melanesia. We find seagrass condition in 65% of PICTs increasing or displaying no discernible trend since records began. Marine conservation across the region overwhelmingly focuses on coral reefs, with seagrass ecosystems marginalised in conservation legislation and policy. Traditional knowledge is playing a greater role in managing local seagrass resources and these approaches are having greater success than contemporary conservation approaches. In a world where the future of seagrass ecosystems is looking progressively dire, the Pacific Islands appears as a global bright spot, where pressures remain relatively low and seagrass more resilient.

Seagrass ecosystem contributions to people's quality of life in the Pacific Island Countries and Territories.

Seagrass ecosystems provide critical contributions (goods and perceived benefits or detriments) for the livelihoods and wellbeing of Pacific Islander peoples. Through in-depth examination of the contributions provided by seagrass ecosystems across the Pacific Island Countries and Territories (PICTs), we find a greater quantity in the Near Oceania (New Guinea, the Bismarck Archipelago and the Solomon Islands) and western Micronesian (Palau and Northern Marianas) regions; indicating a stronger coupling between human society and seagrass ecosystems. We also find many non-material contributions historically have been overlooked and under-appreciated by decision-makers. Closer cultural connections likely motivate guardianship of seagrass ecosystems by Pacific communities to mitigate local anthropogenic pressures. Regional comparisons also shed light on general and specific aspects of the importance of seagrass ecosystems to Pacific Islanders, which are critical for forming evidence-based policy and management to ensure the long-term resilience of seagrass ecosystems and the contributions they provide.

TARGIT-R (Retrospective): 5-Year Follow-Up Evaluation of Intraoperative Radiation Therapy (IORT) for Breast Cancer Performed in North America.

BACKGROUND: Intraoperative radiation therapy (IORT) has been investigated for patients with low-risk, early-stage breast cancer. The The North American experience was evaluated by TARGIT-R (retrospective) to provide outcomes for patients treated in "real-world" clinical practice with breast IORT. This analysis presents a 5-year follow-up assessment. METHODS: TARGIT-R is a multi-institutional retrospective registry of patients who underwent lumpectomy and IORT between the years 2007 and 2013. The primary outcome of the evaluation was ipsilateral breast tumor recurrence (IBTR). RESULTS: The evaluation included 667 patients with a median follow-up period of 5.1 years. Primary IORT (IORT at the time of lumpectomy) was performed for 72%, delayed IORT (after lumpectomy) for 3%, intended boost for 8%, and unintended boost (primary IORT followed by whole-breast radiation) for 17% of the patients. At 5 years, IBTR was 6.6% for all the patients, with 8% for the primary IORT cohort and 1.7% for the unintended-boost cohort. No recurrences were identified in the delayed IORT or intended-boost cohorts. Noncompliance with endocrine therapy (ET) was associated with higher IBTR risk (hazard ratio [HR], 3.67). Patients treated with primary IORT who were complaint with ET had a 5-year IBTR rate of 3.9%. CONCLUSION: The local recurrence rates in this series differ slightly from recent results of randomized IORT trials and are notably higher than in previous published studies using whole-breast radiotherapy for similar patients with early-stage breast cancer. Understanding differences in this retrospective series and the prospective trials will be critical to optimizing patient selection and outcomes going forward.

Assessing intertidal seagrass beds relative to water quality in Vanuatu, South Pacific.

Seagrasses are globally important, but their extent is decreasing due to the impact of human activities and changing climatic conditions. Seagrass meadows provide vital services, but their condition and distribution are not yet well known, particularly in many small tropical Pacific islands. In 2018, observations and samples were collected from intertidal seagrasses of Efate Island, Vanuatu (South Pacific). Observations included canopy height, percentage cover, growth rate and species variety. Water quality samples were also collected in some locations. Our seagrass metrics suggested more challenging conditions for the seagrasses near Port Vila, the main urban area in the island, where water quality analyses indicated higher levels of dissolved inorganic nitrogen and suspended solids.

The current state of continence in Canada: a population representative epidemiological survey.

INTRODUCTION: Data on the prevalence of lower urinary tract symptoms (LUTS) and urinary incontinence (UI) in Canada are dated. This study aims to describe the current prevalence of LUTS and UI, to assess the state of knowledge of these conditions, the treatment for them and the treatment experience of symptomatic persons. MATERIALS AND METHODS: A nationally representative adult (= 18 years) sample was surveyed using a questionnaire based on the EPIC study. The margin of error associated with this probability-based sample was +/-3.1%, 19 times out of 20. RESULTS: Of the 1000 people contacted, (52% female, 48% male), 78.4% were either aware or vaguely aware of the term 'incontinence'. A total of 43.7% of respondents felt that UI was a serious problem that could easily ruin quality of life. When asked, 93.7% of respondents felt that people with UI should seek medical advice, but only 41.4% (27.4% men, 54.3% women) knew what help was available. Of 23.7% of the sample with UI, 145 (61.2%) experienced leakage a few times a month or more frequently and 23.7% had UI for > 11 years. A total of 48.8% of people with UI had initiated a discussion with their healthcare provider about their urinary symptoms, 52.4% within the last year. CONCLUSION: The current distribution of UI in Canada is similar to that found in 2004. There remains a lack of awareness of the available treatments despite an acknowledgement that UI is an important medical condition. Few people had actively engaged with treatments. Men remain less aware and less likely to seek help than women.

Overactive Bladder in Frail Older Adults.

Overactive bladder (OAB) and frailty are multidimensional syndromes, and the prevalence of both increases with age. Little evidence exists for a direct association between OAB and frailty, but urinary urgency may well be a precursor of frailty in older people. Frail older adults are no less deserving of treatment than fit older adults, and lifestyle, behavioral, and pharmacological interventions remain the primary options for treatment, with some evidence for efficacy. Data on onabotulinumtoxinA therapy or percutaneous tibial nerve stimulation in frail older adults are sparse. Frail older adults are often excluded from drug trials, but evidence is accumulating that antimuscarinics and, to a lesser extent, beta-adrenergic agonists are safe, well-tolerated, and effective in older adults. Cognitive impairment associated with frailty should not be used as justification for avoiding the use of antimuscarinics. More studies are required to better understand the association between OAB and frailty, as both are associated with poor outcomes and may be amenable to intervention. Drug trials for OAB treatments should be encouraged to include frail older adults, as this population is highly affected yet often excluded.

Is the belief that urinary incontinence is normal for ageing related to older Canadian women's experience of urinary incontinence?

INTRODUCTION AND HYPOTHESIS: Many women consider urinary incontinence (UI) a normal part of ageing. This belief may contribute to delays in treatment seeking. This study examined the relationship among holding that belief, UI type and severity, impact on quality of life, management and healthcare seeking in a sample of older community-dwelling Canadian women. METHODS: This was a secondary analysis of a controlled trial examining the impact of continence promotion workshops on UI self-management. All women who consented and provided baseline data were included in this analysis regardless of eligibility for the main study. RESULTS: The sample included 4446 women (2022 with UI) of mean (SD) age 78.2 (9.0) years and BMI 26.6 (5.6). The belief that UI is normal for ageing was held by 2149 women [48.3% (83.7% of 1798 incontinent women)] and was not associated with age [adjusted odds ratio (OR) (95% CI): 1.00 (0.99, 1.01), p = 0.72] or perception of overall health. Women with this belief had more impaired QoL compared with the women who felt UI was not normal for ageing [mean (SD) 83.9 (19.4) vs. 87.4 (18.6) (p < 0.01)]. This belief remained unaffected by daily UI and pad use up to 2/day. CONCLUSIONS: More than two-thirds of women thought UI normal for ageing. This belief was not associated with age or perception of overall health. More severe incontinence and greater quantities of pad use did not make women less likely to hold this belief.

TARGIT-R (Retrospective): North American Experience with Intraoperative Radiation Using Low-Kilovoltage X-Rays for Breast Cancer.

BACKGROUND: Single-dose intraoperative radiotherapy (IORT) is an emerging treatment for women with early stage breast cancer. The objective of this study was to define the frequency of IORT use, patient selection, and outcomes of patients treated in North America. METHODS: A multi-institutional retrospective registry was created, and 19 institutions using low-kilovoltage IORT for the treatment of breast cancer entered data on patients treated at their institution before July 31, 2013. Patient selection, IORT treatment details, complications, and recurrences were analyzed. RESULTS: From 2007 to July 31, 2013, a total of 935 women were identified and treated with lumpectomy and IORT. A total of 822 patients had at least 6 months' follow-up documented and were included in the analysis. The number of IORT cases performed increased significantly over time (p < 0.001). The median patient age was 66.8 years. Most patients had disease that was <2 cm in size (90 %) and was estrogen positive (91 %); most patients had invasive ductal cancer (68 %). Of those who had a sentinel lymph node procedure performed, 89 % had negative sentinel lymph nodes. The types of IORT performed were primary IORT in 79 %, secondary IORT in 7 %, or planned boost in 14 %. Complications were low. At a median follow-up of 23.3 months, crude in-breast recurrence was 2.3 % for all patients treated. CONCLUSIONS: IORT use for the treatment of breast cancer is significantly increasing in North America, and physicians are selecting low-risk patients for this treatment option. Low complication and local recurrence rates support IORT as a treatment option for selected women with early stage breast cancer.

Assessing HIV testing and linkage to care activities and providing academic support to public health authorities in Houston, TX.

BACKGROUND: Health departments often have little knowledge of HIV testing and linkage activities outside of those they directly fund. Many health departments also have limited access to outside academic expertise. METHODS: We conducted a survey of health organizations in the Houston/Harris County region to determine the number of HIV tests completed in 2011, activities that organizations conducted to promote linkage to care for persons newly diagnosed with HIV, and barriers to linkage to care. We also convened a Scientific Advisory Council to advise the local health department on HIV prevention activities. RESULTS: In 2012, 55 of 84 organizations (65.5%) completed the survey and 43 of those 55 organizations reported conducting HIV testing, so were included in this analysis. Organizations reported conducting 210,565 HIV tests in 2011 and 50.9% under health department contract. The median number of tests per organization was 1045 (interquartile ratio: 159-3520). More than 90% of the organizations used active linkage to care methods, but only 46.5% had written linkage to care protocols. Barriers to linkage to care most often reported were client refusal followed by staff capacity and funding limitations. The Scientific Advisory Council provided valuable informal expertise to the local health department. CONCLUSIONS: Half of the HIV testing in the Houston/Harris County region is conducted without local health department funding, and half the organizations conducting HIV testing have linkage to care protocols. The findings of the study and Scientific Advisory Council advice have helped the health department with policy, procedures, evaluation tools, and technical assistance offerings.

Identifying and explicating variation among friends with benefits relationships.

This two-study report identifies and validates a typology containing seven types of "friends with benefits relationships" (FWBRs). Study 1 asked heterosexual students to define the term FWBR and to describe their experience with the relationship type. Qualitative analysis of these data identified seven types of FWBRs (true friends, network opportunism, just sex, three types of transition in [successful, failed, and unintentional], and transition out). Study 2 quantitatively differentiates these relationship types in the amount of nonsexual interaction, strength of the friendship at the first sexual interaction, and history of romantic relationships with the FWBR partner (before the FWBR, after it, or both). Results from both studies clearly suggest that FWBRs represent a diverse set of relationship formulations where both the benefits (i.e., repeated sexual contact) and the friends (i.e., relationship between partners) vary widely. In many cases, FWBRs represent a desire for, or an attempt at, shifting the relationship from friends to a romantic partnership. Other implications are discussed, as are limitations and directions for future research. The diverse nature of FWBRs provides challenges for researchers that likely require multiple methods and theoretical frames.

Peripheral 8-OH-DPAT and scopolamine infused into the frontal cortex produce passive avoidance retention impairments in rats.

The present study determined whether peripheral injections of the 5HT(1A) agonist (8-OH-DPAT), scopolamine infusions into the frontal cortex, or a combination of both drug treatments would produce impairments in rats trained on passive avoidance. Using a 2x2 design, rats were infused with either bacteriostatic water or 30 microg/1 microl of scopolamine HCl into the frontal cortex 30 min before being trained on passive avoidance. This was followed by injections (ip) of either 0.1% ascorbic acid/bacteriostatic water or 30 microg/kg of 8-OH-DPAT 15 min later. All subjects were tested for retention 72h later. At test, the initial latency to enter into the black shocked compartment and the total time spent in the white safe compartment (TTW) were recorded. Analysis of the latency data indicated that scopolamine and 8-OH-DPAT, when administered singly or in combination, produced amnesia for the task. Assessment of TTW scores, however, revealed that of the three drug-treated groups, only animals treated with 8-OH-DPAT alone tended to avoid the previously shocked black compartment and spend more time in the white safe compartment. These data indicate that either stimulating 5-HT(1A) or blocking frontal cortical muscarinic receptors at training impairs passive avoidance performance and that the deficit following the latter treatment is somewhat more extensive. Implications for the role frontal cortical muscarinic and 5HT(1A) receptors play in learning and memory are discussed.
