Abstract
Novel supersaturated self-nanoemulsifying drug delivery systems (super-SNEDDS) containing the poorly water-soluble drug halofantrine above equilibrium solubility (150% S(eq)) were compared in vitro and in vivo with conventional SNEDDS containing the drug below equilibrium solubility (75% S(eq)). Pre-concentrates comprising of either medium chain lipids (Captex 300/Capmul MCM) or long chain lipids (soybean oil/Maisine), Cremophor RH40 and ethanol were formulated maintaining the lipid-to-surfactant-to-cosolvent ratio constant (55:35:10, w/w %). The ability of super-SNEDDS to increase the absorption of halofantrine in dogs, as well as the predictivity of the dynamic in vitro lipolysis model was studied. In vitro lipolysis of SNEDDS and super-SNEDDS showed rapid drug precipitation from all formulations while the same drug concentrations in the digestion medium were found during digestion of equal amounts of SNEDDS and super-SNEDDS. Elevated halofantrine solubilisation during in vitro lipolysis was observed only when multiple capsules of conventional SNEDDS were subjected to in vitro digestion. After lipolysis the isolated super-SNEDDS pellets were characterised by XRPD revealing no crystalline halofantrine from any of the investigated formulations. Subsequent dissolution studies of the super-SNEDDS pellet in the lipolysis medium demonstrated enhanced dissolution of halofantrine suggesting that halofantrine in the pellet was amorphous. The enhanced dissolution of the amorphous halofantrine was also reflected in vivo since two capsules of conventional SNEDDS were needed to achieve similar AUC and C(max) as obtained after dosing of a single capsule of super-SNEDDS. The study demonstrated that the absorption of halofantrine was not hampered by drug precipitation. Super-SNEDDS lead to precipitation of halofantrine in an amorphous form, which can be the driving force for enhanced absorption. Since super-SNEDDS were also physically stable for at least 6 months they represent a potential novel oral lipid-based drug delivery system for low aqueous soluble compounds.

Abstract
Mobile device text messaging and other typing is rapidly increasing worldwide. A checklist was utilized to characterize joint postures and typing styles in individuals appearing to be of college age (n = 859) while typing on their mobile devices in public. Gender differences were also ascertained. Almost universally, observed subjects had a flexed neck (91.0%, n = 782), and a non-neutral typing-side wrist (90.3%, n = 776). A greater proportion of males had protracted shoulders (p < 0.01, χ(2) test), while a greater proportion of females had a typing-side inner elbow angle of <90°, particularly while standing (p = 0.03, χ(2) test). 46.1% of subjects typed with both thumbs (two hands holding the mobile device). Just over one-third typed with their right thumb (right hand holding the mobile device). No difference in typing styles between genders was found. Future research should determine whether the non-neutral postures identified may be associated with musculoskeletal disorders.

Abstract
Images obtained by the Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) cameras onboard the Rosetta spacecraft reveal that asteroid 21 Lutetia has a complex geology and one of the highest asteroid densities measured so far, 3.4 ± 0.3 grams per cubic centimeter. The north pole region is covered by a thick layer of regolith, which is seen to flow in major landslides associated with albedo variation. Its geologically complex surface, ancient surface age, and high density suggest that Lutetia is most likely a primordial planetesimal. This contrasts with smaller asteroids visited by previous spacecraft, which are probably shattered bodies, fragments of larger parents, or reaccumulated rubble piles.

Abstract
We describe a previously unreported case of vertebral marrow enhancement owing to collateral circulation in a patient with superior vena cava obstruction. Failure to recognise this phenomenon led to the misdiagnosis of sclerotic bone metastases.

Abstract
The purpose of this study was to investigate family functioning in the relationship between community violence exposure and 1) self-esteem and 2) confrontational coping in a sample of urban youth. Adhering to the tenets of community based participatory research, academic and community partners collaborated on a cross-sectional study with 110 community dwelling urban youth, ages 10–16 living in a city located in the Northeastern United States. As part of a larger survey, this analysis included selected items on lifetime community violence exposure, family functioning, self-esteem and use of confrontational coping strategies in response to community violence. Over 90% of the youth reported some type of lifetime community violence exposure. Controlling for age and gender, older youth and those with healthier family functioning had higher self-esteem; community violence exposure was not associated with self-esteem. Healthier family functioning was associated with decreased use of confrontational coping, though increasing amounts of community violence exposure was still associated with increased confrontational coping. Family can be protective in violent environments. Results from this study directly informed an intervention aimed at youth violence prevention. This study highlights how psychiatric and mental health nurses may be able to address the complex interplay of factors for youth living in violent environments.

Abstract
BACKGROUND Since 2001, the French hospital stay databases (Programme de médicalisation des systèmes d'information, PMSI) have included a unique and anonymous identifier in order to cross-link discharge abstracts from a given patient, within and across hospitals. These data could be used to estimate prevalence for some diseases at a territorial level provided that linkage quality is good enough. Few morbidity data are available at this scale. This study analyzes the link between linkage quality and hospitalization rates in three French regions (Picardy, Brittany and Provence-Alpes-Côte d'Azur-Paca). METHODS We studied short stays in medicine-chirurgical-obstetrical units for the 2004-2005 period (all stays, and stays with mention of cancer or asthma). To study linkage quality, the percentage of linkable stays (no error during the production of the anonymous identifier) was calculated at regional and territorial levels (areas used by regional health authorities). The interquartile range (IQR=third quartile-first quartile) of the percentage of linkable stays was calculated and the link between this percentage and standardized rates of people hospitalized at least once in 2004 or 2005 tested by Spearman correlation coefficients. RESULTS For all stays, percentages of linkable stays were 94.4%, 96.6% and 97.0% in Picardy, Paca and Brittany respectively in 2004-2005. Geographical variation at the territorial level was higher in Picardy (IQR between 4 and 6) than in the two other regions (IQR between 1 and 2). The percentage of linkable stays was positively and significantly associated with the hospitalization rate for all stays and those with mention of cancer in Picardy only. CONCLUSION According to these results, PMSI data earlier than 2006 should be used with precaution; linkage quality should be analyzed before making geographical or time comparisons of hospitalization rates. Comparisons cannot always be made. Other studies should be carried out in other regions, and to analyze recent trends in linkage quality.

Abstract
India is today facing a diabetes epidemic and has the maximum number of patients with diabetes in the world. People with diabetes are more prone to develop all types of infections. Pneumococcal infections are a common cause of morbidity and mortality, and people with diabetes are more prone to develop pneumococcal infections. With the availability of the pneumococcal vaccine, most international organizations now recommend that people with diabetes should be vaccinated against pneumococcal disease. This article tries to provide a balanced review of the place of pneumococcal vaccination in Indian diabetic patients.

Abstract
People with bipolar disorders may have relapse of mood episodes associated with sleep deprivation and postpartum states. Jet lag can cause sleep problems resulting in relapse of mood episodes in vulnerable people. Melatonin synthesized in the pineal gland will normalize the circadian rhythm and prevent the recurrence of mood episodes in predisposed people. We are reporting a case of successful use of melatonin in a 30-year old lady with history of postpartum onset mood disorder and multiple relapses of mania precipitated by jet lag.
