Shannon's index is one of the measures of biodiversity, which is intended to quantify both richness and evenness of the species/individuals in the ecosystem or community. However, application of Shannon's index in the field of substance use among the street children has not been done till date.

This paper is concerned with methods of estimating Shannon's diversity index (SDI), which can be used to capture the variation in the population due to certain characteristics. Under the consideration that the probability of abundance, based on certain characteristics in the population, is a random phenomenon, we derive a Bayesian estimate in connection with Shannon's information measure and their properties (mean and variance), by using a probability matching prior, through simulation and compared it with those of the classical estimates of Shannon. The theoretical framework has been applied to the primary survey data of substance use among the street children in Delhi, collected during 2015. The measure of divers the lower age group (7-10, maximum Bayesian entropy-3.73), followed by the middle (11-14) and upper age group (15-18). Moreover, the estimated variance under the Bayesian paradigm was lesser than that of the classical estimate. There is ample scope for further refinement in these estimates, by considering more covariates that may have a possible role in initiating substance use among street children in developing countries like India.

In recent years there has been a progressive rise in the number of asylum seekers and refugees displaced from their country of origin, with significant social, economic, public health and mental health implications. The aim of this study is to (1) describe the level of psychological distress and frequency of psychiatric disorders in a sample of male asylum seekers and refugees across different ethnic groups resettled in Italy; (2) establish whether the number of traumatic events experienced before, during and after the migration process is associated with level of psychological distress and depressive symptoms.

In two large Italian catchment areas, over a period of 1 year a consecutive series of male asylum seekers and refugees, aged 18 or above and included in the Italian protection system, were screened for psychological distress and psychiatric disorders using validated questionnaires.

During the study period, 252 male asylum seekers or refugees were recruited. More than one-third of the participants problems concerning permit status and asylum procedure, and family reunification, as well as addressing trauma and mental health issues.

In an unselected sample of male asylum seekers and refugees, after around 1 year of resettlement in Italy, the frequency of psychological distress and psychiatric disorders was substantial and clinically relevant. The association between traumatic events, especially post-migration problems, and mental health conditions suggests the need of developing services to assist refugees and asylum seekers to address the multi-faceted problems they experience, such as social support in host country, legal problems concerning permit status and asylum procedure, and family reunification, as well as addressing trauma and mental health issues.

To compare the efficiency of preloaded vs manually loaded IOL (P-IOL vs M-IOL, respectively) delivery systems in cataract surgery in the largest ambulatory surgery center of Northwestern China.

A total of 200 cases were included in this prospective, observational study. Time and motion data were collected in a one- or two-operating room (1-OR or 2-OR, respectively) scenario. A model of the efficiency and revenue implications of introducing a preloaded delivery system for IOLs in cataract surgery was used to estimate the changes in cataract throughput and hospital revenue through transitioning from the M-IOL delivery system to the P-IOL system.

In the 1-OR scenario, the mean total case time was 16.9 min using P-IOL, which was a 7.7% reduction compared with M-IOL (P< 0.01). In the 2-OR scenario, the mean total surgeon time was 10.8 min using P-IOL, which was a 7.8% reduction compared with M-IOL (P< 0.05). By switching from M-IOL to P-IOL, annual throughput will increase by 5.2% (960 cases) in the 1-OR scenario and 7.7% (1440 cases) in the 2-OR scenario, accompany by an increase in revenue of approx. 284,352 USD in the 1-OR scenario and approx. 426,528 USD in the 2-OR scenario.

This report is the first of a comparison of two IOL delivery systems in China using different settings in the scenario. IOL delivery with preloaded systems is time saving in both the 1-OR scenario and the 2-OR scenario. Moreover, switching from the M-IOL delivery system to the P-IOL system holds potential to increase cataract throughput and hospital revenue.

Patent ductus arteriosus (PDA) complicated by Eisenmenger syndrome (ES) remains to be a major cause of morbidity and mortality worldwide. Giving increasing evidences of benefit from targeted therapies, ES patients once thought to be inoperable may have increasing options for management. This study aims to explore whether PDA in patients with ES can be treated with transcatheter closure (TCC).

Between August 2014 and July 2016, four of fifteen PDA-ES patients whose Qp/Qs improved significantly and Qp/Qs > 1.5 after acute vasodilator testing with 100% oxygen were selected to receive TCC and pulmonary vasodilator therapy. PAH-targeted drugs were prescribed before and after occlusion for all. Trial occlusion was performed before permanent closure.

The first TCC failed after initiation of PAH-targeted drugs for 6months in four patients. After the medication was adjusted and extended to 12months, TCC was performed for all without hemodynamic intolerances during perioperative period. XL413 Pulmonary artery systolic pressure (PASP) was significantly decreased (≥ 40%) immediately after TCC.
