Outcomes For Street Children and Youth Under Multidisciplinary Care in a Drop-In Centre in Tegucigalpa, Honduras
BACKGROUND: There is little evidence to describe the feasibility and outcomes of services for the care of street children and youth in low-income countries. AIMS: To describe the outcomes of a multidisciplinary case management approach delivered in a drop-in centre for street children and youth. METHODS: A longitudinal study of street children and youth followed in an urban drop-in centre. Four hundred (400) street children and youth received a multidisciplinary case management therapeutic package based on the community reinforcement approach. The main outcomes were changes in psychological distress, substance abuse and social situation scores. RESULTS: The median follow-up time for the cohort was 18 months. There were reductions in the levels of psychological distress (p = 0.0001) and substance abuse (p ≤ 0.0001) in the cohort as well as an improvement in the social situation of street children and youth (p = 0.0001). There was a main effect of gender (p < 0.001) and a significant interaction of gender over time (p < 0.001) on improvements in levels of psychological distress. Survival analysis showed that the probability of remaining on substances at 12 months was 0.76 (95% CI: 0.69-0.81) and 0.51 (95% CI: 0.42-0.59) at 24 months. At 12 months, fewer female patients remained using substances compared to male (p < 0.01). CONCLUSION: To be most effective, programmes and strategies for children and youth in street situations in developing countries should target both their health and social needs
Informal rental housing in Colombia: an essential option for low-income households
Around the world, rental housing is frequently seen as secondary to home ownership; yet it plays a crucial role in many countries. In particular, rental housing in urban informal neighbourhoods has a critical but consistently overlooked role in housing the most vulnerable households in the Global South. If better policy and practice are to be pursued, there is a need for improved data on rental housing in urban informal settlements, and in particular, better understanding of ‘the lived experiences of the poor’. This paper responds to these empirical gaps in debates on informality and rental housing with qualitative research on residents’ experiences of informal rented housing in two Colombian cities, Bogotá and Cali. The paper frames informal rental housing as an essential option for diverse low-income households for whom ownership is not accessible or attractive. In this way, it also contributes to policy and theoretical debates calling for a better understanding of the dynamics, possibilities and potential of informal housing
Three Short Period Jupiters from TESS
We report the confirmation and mass determination of three hot Jupiters
discovered by the Transiting Exoplanet Survey Satellite (TESS) mission: HIP
65Ab (TOI-129, TIC-201248411) is an ultra-short-period Jupiter orbiting a
bright (V=11.1 mag) K4-dwarf every 0.98 days. It is a massive 3.213 +/- 0.078
Mjup planet in a grazing transit configuration with an impact parameter of b =
1.17 +0.10/-0.08. As a result the radius is poorly constrained, 2.03
+0.61/-0.49 Rjup. The planet's distance to its host star is less than twice the
separation at which it would be destroyed by Roche lobe overflow. It is
expected to spiral into HIP 65A on a timescale ranging from 80 Myr to a few
gigayears, assuming a reduced tidal dissipation quality factor of Qs' = 10^7 -
10^9. We performed a full phase-curve analysis of the TESS data and detected
both illumination- and ellipsoidal variations as well as Doppler boosting. HIP
65A is part of a binary stellar system, with HIP 65B separated by 269 AU (3.95
arcsec on sky). TOI-157b (TIC 140691463) is a typical hot Jupiter with a mass
of 1.18 +/- 0.13 Mjup and a radius of 1.29 +/- 0.02 Rjup. It has a period of
2.08 days, which corresponds to a separation of just 0.03 AU. This makes
TOI-157 an interesting system, as the host star is an evolved G9 sub-giant star
(V=12.7). TOI-169b (TIC 183120439) is a bloated Jupiter orbiting a V=12.4
G-type star. It has a mass of 0.79 +/- 0.06 Mjup and a radius of 1.09
+0.08/-0.05 Rjup. Despite having the longest orbital period (P = 2.26 days) of
the three planets, TOI-169b receives the most irradiation and is situated on
the edge of the Neptune desert. All three host stars are metal rich with [Fe/H]
ranging from 0.18 - 0.24.Comment: Published in A&

Global variations in diabetes mellitus based on fasting glucose and haemogloblin A1c
Fasting plasma glucose (FPG) and haemoglobin A1c (HbA1c) are both used to diagnose
diabetes, but may identify different people as having diabetes. We used data from 117
population-based studies and quantified, in different world regions, the prevalence of
diagnosed diabetes, and whether those who were previously undiagnosed and detected
as having diabetes in survey screening had elevated FPG, HbA1c, or both. We developed
prediction equations for estimating the probability that a person without previously
diagnosed diabetes, and at a specific level of FPG, had elevated HbA1c, and vice versa.
The age-standardised proportion of diabetes that was previously undiagnosed, and
detected in survey screening, ranged from 30% in the high-income western region to 66%
in south Asia. Among those with screen-detected diabetes with either test, the agestandardised
proportion who had elevated levels of both FPG and HbA1c was 29-39%
across regions; the remainder had discordant elevation of FPG or HbA1c. In most low- and
middle-income regions, isolated elevated HbA1c more common than isolated elevated
FPG. In these regions, the use of FPG alone may delay diabetes diagnosis and
underestimate diabetes prevalence. Our prediction equations help allocate finite
resources for measuring HbA1c to reduce the global gap in diabetes diagnosis and
surveillance.peer-reviewe
