COVID-19 and Substance Use Disorders: Recommendations to a Comprehensive Healthcare Response. An International Society of Addiction Medicine Practice and Policy Interest Group Position Paper.

Coronavirus Disease 2019 (COVID-19) is escalating all over the world and has higher morbidities and mortalities in certain vulnerable populations. People Who Use Drugs (PWUD) are a marginalized and stigmatized group with weaker immunity responses, vulnerability to stress, poor health conditions, high-risk behaviors, and lower access to health care services. These conditions put them at a higher risk of COVID-19 infection and its complications.

A tentative component analysis of Norjizak: A new abused drug in Iran.

Norjizak is a new drug abused in the past few years in Iran with symptoms and complications distinct from other common forms of drug and characterized by higher rate of mortality. The present study aims to analyze the chemical components of this substance. Five samples were obtained from abusers referring from different areas of Tehran to a treatment clinic.

Severe neonatal hyperbilirubinemia leading to exchange transfusion.

Background: Severe neonatal hyperbilirubinemia is associated with significant morbidity and mortality. This study was conducted to investigate the causes of severe hyperbilirubinemia leading to Exchange Transfusion (ET) from March 2009 to March 2011 in Bahrami children hospital, Tehran, Iran in order to establish guidelines to prevent profound jaundice & ET.

Methods: 94 neonates underwent ET for severe hyperbilirubinemia data for demographic data, and onset of jaundice, history of severe hyperbilirubinemia in siblings, blood group of both mother and neonate, G6PD activity, hemoglobin, hematocrite, reticulocyte count, peripheral blood smear, total and direct bilirubin before and after ET, direct and indirect Coombs, times of transfusion and the cause of hyperbilirubinemia were all recorded for analysis.

Component analysis of Iranian crack; a newly abused narcotic substance in iran.

Iranian crack is a new form of narcotic substance that has found widespread prevalence in Iran in the past years. Crack only nominally resembles crack cocaine as it is widely different in its clinical signs. Thus the present study aims to quantify the chemical combination of this drug.

Relationships between pregnancy rates following in vitro fertilization or intracytoplasmic sperm injection and endometrial thickness and pattern.

Objective: To investigate the role of endometrial thickness and pattern on the day of human chorionic gonadotropin (hCG) administration on in vitro fertilization (IVF)/intracytoplasmic injection (ICSI) outcome.

Study Design: A total of 150 infertile women undergoing embryo transfer after IVF/ICSI cycles were studied in a prospective survey. Sonographic features of the endometrium (thickness and pattern) on the day of hCG administration, hormonal profile (progesterone, estradiol, FSH, LH) and various other variables (maternal age, causes and duration of infertility, duration of treatment, number of human menopausal gonadotropin (hMG) ampoules administered, and number of oocytes retrieved) were evaluated.
