RESUMEN
BACKGROUND: Young people make up for 24.5 % of Latin America's population. Inadequate supply of specific and timely sexual and reproductive health (SRH) services and sexuality education for young people increases their risk of sexual and reproductive ill health. Colombia is one of the few countries in Latin America that has implemented and scaled up specific and differentiated health and SRH services-termed as its Youth Friendly Health Services (YFHS) Model. OBJECTIVE: To provide a systematic description of the crucial factors that facilitated and hindered the scale up process of the YFHS Model in Colombia. METHODS: A comprehensive literature search on SRH services for young people and national efforts to improve their quality of care in Colombia and neighbouring countries was carried out along with interviews with a selection of key stakeholders. The information gathered was analysed using the World Health Organization-ExpandNet framework (WHO-ExpandNet). RESULTS/DISCUSSION: In 7 years (2007-2013) of the implementation of the YFHS Model in Colombia more than 800 clinics nationally have been made youth friendly. By 2013, 536 municipalities in 32 departments had YFHS, resulting in coverage of 52 % of municipalities offering YHFS. The analysis using the WHO-ExpandNet framework identified five elements that enabled the scale up process: Clear policies and implementation guidelines on YFHS, clear attributes of the user organization and resource team, establishment and implementation of an inter-sectoral and interagency strategy, identification of and support to stakeholders and advocates of YFHS, and solid monitoring and evaluation. The elements that limited or slowed down the scale up effort were: Insufficient number of health personnel trained in youth health and SRH, a high turnover of health personnel, a decentralized health security system, inadequate supply of financial and human resources, and negative perceptions among community members about providing SRH information and services to young people. CONCLUSION: Colombia's experience shows that for large-scale implementation of youth health programmes, clear policies and implementation guidelines, support from institutional leaders and authorities who become champions of YFHS, continuous training of health personnel, and inclusion of users in the design and monitoring of these services are key.

Cerberus rynchops (dog-faced water snake) belongs to Homalopsidae of Colubroidea (rear-fanged snakes). So far, venom compositions of snakes of the Homalopsidae family are not known. To determine the venom composition of C. rynchops, we have used both transcriptomics and proteomics approaches. The venom gland transcriptome revealed 104 ESTs and the presence of three known snake protein families, namely, metalloprotease, CRISP, and C-type lectin. In addition, we identified two proteins that showed sequence homology to ficolin, a mammalian protein with collagen-like and fibrinogen-like domains. We named them as ryncolin 1 and ryncolin 2 (rynchops ficolin) and this new family of snake venom proteins as veficolins (venom ficolins). On the basis of its structural similarity to ficolin, we speculate that ryncolins may induce platelet aggregation and/or initiate complement activation. To determine the proteome, the whole C. rynchops venom was trypsinized and fractionated by reverse phase HPLC followed by MALDI-MS/MS analysis of the tryptic peptides. Analysis of the tandem mass spectrometric data indicated the presence of all protein families compared to the translated cDNA library. Overall, our combined approach of transcriptomics and proteomics revealed that C. rynchops venom is among the least complex snake venom characterized to date despite the presence of a new family of snake venom proteins.

Bacillus cereus, a ubiquitous, endospore-forming, aerobic gram-positive bacillus, is primarily associated with toxin-mediated food poisoning. Frequently, isolates of Bacillus species from clinical specimens are discussed as contaminants. We report a rapidly fatal case of disseminated infection due to B cereus in a patient receiving induction chemotherapy for M0 acute leukemia. A short clinical syndrome of nausea and vomiting preceded neurologic symptoms. Autopsy showed extensive meningoencephalitis with subarachnoid hemorrhage and multiple liver abscesses. Areas of necrosis were devoid of any inflammatory response consistent with a severely immunocompromised state. The organism was isolated from immediate premortem and autopsy blood specimens. This case illustrates the possibility and severity of true B cereus infections in immunocompromised patients, the clinicopathologic features of which are as yet not well defined.
