- Background: Uterine prolapse (UP), which affects about 10% of women of reproductive age in Nepal, is the most frequently reported cause of poor health in women of reproductive age and postmenopausal women. Currently, women's awareness of UP is unknown, and attempts to unravel the UP problem are inadequate. This study aims to assess UP knowledge among married reproductive women, and determine the association between UP knowledge and socioeconomic characteristics. Methods: Our cross-sectional descriptive study investigated 25 districts representing all five administrative regions, three ecological zones, and urban and rural settings. We used structured questionnaires to interview 4,693 married women aged 15-49 years. We assessed UP knowledge by asking women whether they had ever heard about UP, followed by specific questions about symptoms and preventive measures. Descriptive statistics characterized the study population regarding socioeconomic status, assessed how many participants had ever heard about UP, and determined UP knowledge level among participants who had heard about the condition. Simple regression analysis identified a possible association between socioeconomic characteristics, ever heard about UP, and level of UP knowledge. Results: Mean age of participants was 30 years (SD [standard deviation] 7.4), 67.5% were educated, 48% belonged to the advantaged Brahmin and Chhetri groups, and 22.2% were Janajati from the hill and terai zones. Fifty-three percent had never heard about UP. Among women who had heard about UP, 37.5% had satisfactory knowledge. Any knowledge about UP was associated with both urban and rural settings, age group, and education level. However, satisfactory knowledge about UP was associated with administrative region, ecological zones, caste/ethnic group, and age group of women. Conclusion: Fifty-three percent of participants had never heard about UP, and UP knowledge level was satisfactory in 37.% of those who had ever heard about UP. Any knowledge was associated with urban/rural setting, age group, and education level, whereas satisfactory knowledge was associated with geography, caste/ethnic group, and age group. UP-related health promotion programs should target women from all caste/ethnic groups, age groups, and education levels, including urban and rural communities. © 2014 Shrestha et al.

- What determines the nuclear radio emission in local galaxies? To address this question, we combine optical [O iii] line emission, robust black hole (BH) mass estimates, and high-resolution e-MERLIN 1.5-GHz data, from the LeMMINGs survey, of a statistically complete sample of 280 nearby optically active (LINER and Seyfert) and inactive [H ii and absorption line galaxies (ALGs)] galaxies. Using [O iii] luminosity (L[O III]) as a proxy for the accretion power, local galaxies follow distinct sequences in the optical-radio planes of BH activity, which suggest different origins of the nuclear radio emission for the optical classes. The 1.5-GHz radio luminosity of their parsec-scale cores (Lcore) is found to scale with BH mass (MBH) and [O iii] luminosity. Below MBH ∼106.5 M⊙, stellar processes from non-jetted H ii galaxies dominate with Lcore ∝ MBH0.61 ± 0.33 and Lcore ∝ L[O III]0.79 ± 0.30. Above MBH ∼106.5 M⊙, accretion-driven processes dominate with Lcore ∝ MBH1.5-1.65 and Lcore ∝ L[O III]0.99-1.31 for active galaxies: radio-quiet/loud LINERs, Seyferts, and jetted H ii galaxies always display (although low) signatures of radio-emitting BH activity, with L1.5 GHz ≳ 1019.8 W Hz-1 and MBH ≳ 107 M⊙, on a broad range of Eddington-scaled accretion rates (m). Radio-quiet and radio-loud LINERs are powered by low-m discs launching sub-relativistic and relativistic jets, respectively. Low-power slow jets and disc/corona winds from moderately high to high-m discs account for the compact and edge-brightened jets of Seyferts, respectively. Jetted H ii galaxies may host weakly active BHs. Fuel-starved BHs and recurrent activity account for ALG properties. In conclusion, specific accretion-ejection states of active BHs determine the radio production and the optical classification of local active galaxies.

- All 280 of the statistically complete Palomar sample of nearby ( < 120 Mpc) galaxies δ> 20 ◦have been observed at 1.5 GHz as part of the LeMMINGs e -MERLIN le gac y surv e y. Here, we present Chandr a X-ray observations of the nuclei of 213 of these galaxies, including a statistically complete sub-set of 113 galaxies in the declination range 40 ◦<δ< 65 ◦. We observed galaxies of all optical spectral types, including 'active' galaxies [e.g. low-ionization nuclear emission line regions (LINERs) and Seyferts] and 'inactive' galaxies like H II galaxies and absorption line galaxies (ALG). The X-ray flux limit of our surv e y is 1.65 ×10 -14 erg s -1 cm -2 (0.3 -10 keV). We detect X-ray emission coincident within 2 arcsec of the nucleus in 150/213 galaxies, including 13/14 Seyferts, 68/77 LINERs, 13/22 ALGs and 56/100 H II galaxies, but cannot completely rule out contamination from non-AGN processes in sources with nuclear luminosities ≲ 10 39 erg s -1 . We construct an X-ray Luminosity function (XLF) and find that the local galaxy XLF, when including all active galactic nucleus (AGN) types, can be represented as a single power law of slope -0.54 ±0.06. The Eddington ratio of the Seyferts is usually 2 -4 decades higher than that of the LINERs, ALGs, and H II galaxies, which are mostly detected with Eddington ratios ≲ 10 -3 . Using [ O III ] line measurements and black hole masses from the literature, we show that LINERs, H II galaxies and ALGs follow similar correlations to low luminosities, suggesting that some 'inactive' galaxies may harbour AGN.
