Background:
Lead is known for their neurotoxicity and compared to adults, children are more vulnerable to lead exposure. Varieties of diseases are developed by lead induced damage in children, including decreased intelligent quotient and behavioral changes, such as anxiety. In normal condition lead does not exist in children’s blood and this toxic heavy metal enters into human body through respiratory way and accumulates in blood and bone to harm neurodegenerative and urinary systems. Therefore, the present study aimed to investigate whether the emitted lead from recycling factory for lead acid batteries, which is located in 9 km distance from Khonkhor town and 39 km faraway from Ulaanbaatar city with north-east direction, is affecting the intelligence of the local children.
Methods:
There are 13 children involved in this study and the participants are divided into two
groups, including subjects, who live in areas outside (n=10) and within (n=3) the 1000 m region of
the factory zone. The blood sampling was collected according to WHO guidelines and lead level
in blood was determined by Leadcare instruments at Environmental health and toxicological
laboratory of National Center for Public Health. The intelligence analysis was conducted by
Raven’s progressive matrices test. And the statistical analysis was performed by SPSS 21 software
to assess correlation of blood lead levels and the intelligence among participated children.
Results:
It is resulted that average lead level for children’s blood samples is 3.1±1.5 ug/dL and
which is found beyond the acceptable range in WHO guidelines. The children’s intelligence was
assessed by Raven’s colored Progressive Matrices analysis, which is practically accepted in China,
which estimated that average intelligence score of participants were 48.3±13.2. According to
correlation analysis of age, sex, intelligence and blood lead level, there was a weak positive
correlation was found between children’s age and lead level in blood. In contrast, a weak reverse
correlation was observed in regarding with sex and blood lead level and intelligence score was
weakly reverse correlated with the lead level in children’s blood samples.
Conclusions
The determined average lead level was 3.1±1.5 ug/dL for blood samples collected
from 13 children who involved in this study and the value is found under the WHO guidance
value. Furthermore, their average intelligence score was estimated as 48.3±13.2. The comparative
analysis shown that intelligence score of 3 children, who lives within 1000 m region of the recycling
factory was lower than those who lives in outside region of the factory and have same age.

INTRODUCTION:
Nursing home (NH) residents with out-of-hospital cardiac arrests (OHCA) have unique resuscitation priorities. This study aimed to describe OHCA characteristics in NH residents and identify independent predictors of survival.
MATERIALS AND METHODS:
OHCA cases between 2010-16 in the Pan-Asian Resuscitation Outcomes Study were retrospectively analysed. Patients aged <18 years old and non-emergency cases were excluded. Primary outcome was survival at discharge or 30 days. Good neurological outcome was defined as a cerebral performance score between 1-2.
RESULTS:
A total of 12,112 cases were included. Of these, 449 (3.7%) were NH residents who were older (median age 79 years, range 69-87 years) and more likely to have a history of stroke, heart and respiratory diseases. Fewer NH OHCA had presumed cardiac aetiology (62% vs 70%, <0.01) and initial shockable rhythm (8.9% vs 18%, <0.01), but had higher incidence of bystander cardiopulmonary resuscitation (74% vs 43%, <0.01) and defibrillator use (8.5% vs 2.8%, <0.01). Non-NH (2.8%) residents had better neurological outcomes than NH (0.9%) residents ( <0.05). Factors associated with survival for cardiac aetiology included age <65 years old, witnessed arrest, bystander defibrillator use and initial shockable rhythm; for non-cardiac aetiology, these included witnessed arrest (adjusted odds ratio [AOR] 3.8, <0.001) and initial shockable rhythm (AOR 5.7, <0.001).
CONCLUSION
Neurological outcomes were poorer in NH survivors of OHCA. These findings should inform health policies on termination of resuscitation, advance care directives and do-not-resuscitate orders in this population.

A once-daily formulation of tacrolimus, Advagraf®, is increasingly being used in place of twice-daily tacrolimus, Prograf®, as a standard immunosuppressive agent for transplant patients. In this study, the clinical safety and efficacy of Advagraf® were compared with Prograf®, among multi-ethnic Malaysian renal transplanted population.
