Introduction: This study aimed to determine the views and practices of healthcare providers and barriers they encountered when implementing the national health screening program for men in a public primary care setting in Malaysia. Methods: An online survey was conducted among healthcare providers across public health clinics in Malaysia. All family medicine specialists, medical officers, nurses and assistant medical officers involved in the screening program for adult men were invited to answer a 51-item questionnaire via email or WhatsApp. The questionnaire comprised five sections: participants' socio-demographic information, current screening practices, barriers and facilitators to using the screening tool, and views on the content and format of the screening tool. Results: A total of 231 healthcare providers from 129 health clinics participated in this survey. Among them, 37.44% perceived the implementation of the screening program as a "top-down decision." Although 37.44% found the screening tool for adult men "useful," some felt that it was "time consuming" to fill out (38.2%) and "lengthy" (28.3%). In addition, 'adult men refuse to answer' (24.1%) was cited as the most common patient-related barrier. Conclusions: This study provided useful insights into the challenges encountered by the public healthcare providers when implementing a national screening program for men. The screening tool for adult men should be revised to make it more user-friendly. Further studies should explore the reasons why men were reluctant to participate in health screenings, thus enhancing the implementation of screening programs in primary care. [ABSTRACT FROM AUTHOR]

Objective: There is currently no documentation on the availability and implementation of policies related to men's health in Asia. This Delphi study aimed to achieve an Asian consensus on men's health policy based on the opinions and recommendations from men's health key opinion leaders. Study design: A two-phase Delphi online survey was used to gather information from men's health stakeholders across Asian countries. Methods: All stakeholders were invited to participate in the survey through men's health conferences, personal contacts, recommendations from international men's health organizations and snowballing method. Stakeholders were asked about their concerns on 17 men's health key issues as well as their opinion on the availability and recommendations on men's health policies and programmes in their countries. Results: There were a total of 128 stakeholders (policy makers, clinicians, researchers and consumers), from 28 Asian countries, who responded in the survey. Up to 85% of stakeholders were concerned about various men's health issues in Asia and in their respective country, particularly in smoking, ischaemic heart disease and high blood pressure. There is a lack of men's health policies and programmes in Asia (availability = 11.6-43.5%) and up to 92.9% of stakeholders recommended that these should be developed. Conclusions: These findings call for policy change and development, and more importantly a concerted effort to elevate men's health status in Asia. [ABSTRACT FROM AUTHOR]

Satellite DNA (satDNA) is a major component of genomes but relatively little is known about the fine-scale organization of unrelated satDNAs residing at the same chromosome location, and the sequence structure and dynamics of satDNA junctions. We studied the organization and sequence junctions of two nonhomologous satDNAs, pBuM and DBC-150, in three species from the neotropical Drosophila buzzatii cluster (repleta group). In situ hybridization to microchromosomes, interphase nuclei and extended DNA fibers showed frequent interspersion of the two satellites in D. gouveai, D. antonietae and, to a lesser extent, D. seriema. We isolated by PCR six pBuM × DBC-150 junctions: four are exclusive to D. gouveai and two are exclusive to D. antonietae. The six junction breakpoints occur at different positions within monomers, suggesting independent origin. Four junctions showed abrupt transitions between the two satellites, whereas two junctions showed a distinct 10 bp tandem duplication before the junction. Unlike pBuM, DBC-150 junction repeats are more variable than randomly cloned monomers and showed diagnostic features in common to a 3-monomer higher-order repeat seen in the sister species D. serido. The high levels of interspersion between pBuM and DBC-150 repeats suggest extensive rearrangements between the two satellites, maybe favored by specific features of the microchromosomes. Our interpretation is that the junctions evolved by multiples events of illegitimate recombination between nonhomologous satDNA repeats, with subsequent rounds of unequal crossing-over expanding the copy number of some of the junctions.Heredity (2009) 102, 453–464; doi:10.1038/hdy.2009.9; published online 4 March 2009 [ABSTRACT FROM AUTHOR]
