Arsenic (As) and lead (Pb) commonly co-exist with high concentrations in paddy soil mainly due to human activities in south of China. This study investigates the effect of ferrous sulfate (FeSO4) amendment and water management on rice growth and arsenic (As) and lead (Pb) accumulation in rice plants. A paddy soil co-contaminated with As and Pb was chosen for the pot experiment with three FeSO4 levels (0, 0.25, and 1%, on a dry weight basis) and two water managements (flooded, non-flooded). The concentrations of As and Pb in iron plaques and rice plants were determined...

BACKGROUND: A national surveillance system for health care-associated infections (HAIs) in Iran is relatively new, and an update on incidence and mortality rates can aid clinicians and stakeholders in development of new guidelines and imperative modifications to be made. METHODS: Data were extracted from the national HAIs surveillance software for more than 7 million hospitalizations during 2015. Data regarding age, gender, deaths, ward of admission, and microbiologic findings were collected and analyzed...

BACKGROUND: Burn injury is a global health problem mainly occurring in developing countries. The Nepal Cleft and Burn Centre at Kirtipur Hospital, Kathmandu, has been providing the acute burn care since 2013 with 7 intensive care unit beds, 30 general beds, and 2 dedicated operating rooms. A similar descriptive study was performed in this center in 2014. These studies will be helpful for developing prevention strategies and monitoring the progress in the standard of care of acute burn patients...

We conducted a survey in a random sample of 514 Quebec nurses caring for the elderly to assess their attitudes towards extending medical aid in dying to incompetent patients and to explore associated factors. Attitudes were measured using clinical vignettes featuring a hypothetical patient with Alzheimer disease. Vignettes varied according to the stage of the disease (advanced or terminal) and the presence or absence of a written request. Of the 291 respondents, 83.5% agreed with the current legislation that allows physicians to administer aid in dying to competent patients who are at the end of life and suffer unbearably...

We report a case of a 39-year-old woman who died of fulminant pulmonary thromboembolism (PE). Autopsy showed classical findings of fulminant PE with occlusion of the bilateral main stem pulmonary arteries. Ancillary testing revealed inherited thrombophilia (Prothrombin 20,210 G > A and MTHFR 677 C > T mutation). Pre-autopsy postmortem computed tomography was used to test whether virtual imaging studies alone (virtual autopsy) would be sufficient to detect PE. Our studies show that computed tomography (CT) can differentiate antemortem clots from a postmortem clot in certain cases, particularly when combined with magnetic resonance imaging (MRI), which is superior in the assessment of soft tissue...

Despite overwhelming data on predictors of inpatient mortality, it is unclear which variables are the most instructive in predicting mortality of patients in departments of internal medicine. This study aims to identify the most informative predictors of inpatient mortality, and builds a prediction model on an individual level, given a constellation of patient characteristics. We use a penalized method for developing the prediction model by applying the least-absolute-shrinkage and selection-operator regression...

Euthanasia is a controversial and complex issue, especially when involving incompetent patients. On December 10, 2015, Quebec became the first Canadian province to give access to medical aid in dying (MAiD) (ie, euthanasia performed by a physician) to competent patients who satisfy strictly defined criteria. Less than 2 years later, Quebec is considering extending MAiD to incompetent patients who made an advance request. With the objective of contributing scientific data to current societal debates, we conducted a survey among 471 informal caregivers of persons with dementia, reached through Alzheimer Societies...

PURPOSE: The goal of this study was to evaluate the fracture resistances of various monolithic crowns fabricated by computer-aided design and computer-aided manufacturing (CAD/CAM) with different thickness. MATERIALS AND METHODS: Test dies were fabricated as mandibular molar forms with occlusal reductions using CAD/CAM. With different occlusal thickness (1.0 or 1.5 mm), a polymer-infiltrated ceramic network (Enamic, EN), and zirconia-reinforced lithium silicate (Suprinity, SU and Celtra-Duo, CD) were used to fabricate molar crowns...

We present a patient with advanced AIDS admitted with recurrent shock of unclear aetiology, fevers, altered mental status and refractory cytopenias. His case posed a diagnostic challenge because evaluation of septic shock in the setting of advanced AIDS requires a time-consuming work-up for broad infectious aetiologies that can delay consideration of other diagnoses, including primary or secondary haemophagocytic lymphohistiocytosis (HLH). After this patient did not improve with supportive care and empiric antimicrobials, there was concern for HLH given that he met ≥5 of the HLH consortium criteria...

BACKGROUND: Patients with mild-to-moderate traumatic brain injury (TBI) are often primarily managed by emergency medicine and trauma/acute care physicians. The Brain Injury Guidelines (BIG) were developed at an ACS-accredited level 1 trauma center to triage mild-to-moderate TBI patients and help identify patients who warrant neurosurgical consultation. The BIG have not been validated at a level III trauma center. We hypothesized that BIG criteria can be safely adapted to an ACS-accredited level III trauma center to guide transfers to a higher echelon of care...

BACKGROUND: Deaths in HIV-positive people have decreased since the introduction of highly active antiretroviral therapy (HAART) in 1996. Fewer AIDS-related deaths and an ageing cohort have resulted in an increase in the proportion of HIV patients dying from non-AIDS-related disorders. Here we describe mortality and causes of death in people diagnosed with HIV in the HAART era compared with the general population. METHODS: In this observational analysis, we linked cohort data collected by Public Health England (PHE) for individuals aged 15 years and older, diagnosed with HIV in England and Wales from 1997 to 2012, to the Office for National Statistics (ONS) national mortality register...

Lifelong ART is essential to reducing HIV mortality and ending the epidemic, however the interplay between socioeconomic position and long-term outcomes of HIV-infected persons receiving antiretroviral therapy (ART) in sub-Saharan Africa is unknown. Furthering the understanding of factors related to long-term ART outcomes in this important region will aid the successful scale-up of ART programs. We enrolled 559 HIV-infected Ugandan adults starting ART in 2004-2005 at the Infectious Diseases Institute in Kampala, Uganda and followed them for 10 years...

Most extremely premature infants die in the intensive care unit or suffer significant neurologic impairment. Many therapies result in unhealthy consequences, and the emotional and financial turmoil for families warrant reappraisal of our motives. Shared decision-making and informed consent in preference-sensitive conditions imply the family: (a) understands the medical problem, (b) grasps the risks and benefits of each therapy, (c) has the opportunity to ask questions and reflect upon options, (d) knows their values and preferences are understood, and (e) accepts or declines therapies without judgment or penalty...

BACKGROUND: Most people would prefer to die at home as opposed to hospital; therefore, understanding mortality patterns by place of death is essential for health resources allocation. AIM: We examined trends and risk factors for hospital death in conditions needing palliative care in a country without integrated palliative care. DESIGN: This is a death certificate study. We examined factors associated with hospital death using logistic regression...

The HIV infection is responsible for the most devastating global pandemic of the last century. More than 39 million people have died of HIV/AIDS since 1981. The development of the antiretroviral (ARV) treatment begins with the discovery of zidovudine a nucleoside reverse transcriptase inhibitor. This breakthrough was followed by other ARV drug classes and representatives. Presently, HIV treatment employs 27 ARV representatives belonging to five different classes. Despite the proven benefits of ARV treatment and its long-term control of the HIV infection, there is an increasing concern about the numerous adverse effects and resistance to current ARV drugs...

REVIEW
Dianne C Daniel, Edward M Johnson
The PURA gene encodes Pur-alpha, a 322 amino acid protein with repeated nucleic acid binding domains that are highly conserved from bacteria through humans. PUR genes with a single copy of this domain have been detected so far in spirochetes and bacteroides. Lower eukaryotes possess one copy of the PUR gene, whereas chordates possess 1-4 PUR family members. Human PUR genes encode Pur-alpha (Pura), Pur-beta (Purb) and two forms of Pur-gamma (Purg). Pur-alpha is a protein that binds specific DNA and RNA sequence elements...

INTRODUCTION: The prevalence of smoking among people living with HIV/AIDS (PLWHA) remains higher than the general population. Life expectancy among PLWHA has increased over the past decade, however, PLWHA who smoke will die younger than their non-smoking peers. The primary aim of this pilot study was to examine the effects of warm handoff versus fax referral to the quitline for smoking cessation among hospitalized smokers living with HIV/AIDS. METHODS: 25 smokers with a diagnosis of HIV/AIDS hospitalized at a Midwestern academic medical center in 2012-2013 (19 male; mean age=47...

This paper examines the convergence of culture, myths, and taboos surrounding reproductive health issues African immigrant women, living in the United States, learned during childhood in their countries of origin. We also discuss how mothers' perceptions of reproductive health education (RHE) influenced the education of their own daughters aged 10-14 years. This was a qualitative descriptive study. Data were collected via interviews and demographic survey. The sample size was 20 African immigrant mothers living in a mid-sized city in the U...
