Case Report: Cerebral Venous Sinus Thrombosis and COVID-19 Infection.

Coronavirus disease-2019 is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 virus). Coronavirus disease-2019 (COVID-19) was declared a pandemic in March 2020 and has changed our lives in many ways. This infection induces a hypercoagulable state leading to arterial and venous thrombosis, but the exact pathophysiology of thrombosis is unknown. However, various theories have been postulated including excessive cytokine release, endothelial activation, and disseminated intravascular coagulation (DIC). We present a patient diagnosed with cerebral venous sinus thrombosis (CVST) with COVID-19 infection. A 66-year-old man presented to a hospital for evaluation of persistent headaches. He tested positive for COVID-19, and MRI of the brain and CT venogram revealed CVST. He was started on heparin drip in the hospital and transitioned to oral anticoagulants at the time of discharge. His headaches improved with treatment. Even though headache is the most frequent and initial symptom of cerebral venous thrombosis, it is rarely the only symptom. A high index of suspicion is therefore required to diagnose CVST especially if the patient presents with a simple complaint like a headache. Common complaints can delay the diagnosis leading to disease progression. Considering the high mortality rates in patients diagnosed with CVST, we suggest the importance of knowing the association between COVID-19 infection and CVST, especially in susceptible patients.

The burden of unintentional injuries among the under-five population in South Asia.

BACKGROUND: Childhood injuries are a growing global concern, one that falls disproportionately on developing countries where public health systems are least prepared to address this problem. AIM: This study assesses the impact of childhood injuries in the developing region of South Asia in order to set forth an agenda for improving child health in that region. METHODS: A systematic review was conducted for literature with quantitative data on unintentional injuries in children 0-4 years of age published between 1980 and 2007. The information was collated to estimate the mean, weighted mean and mortality rate for each type of injury. The rates were then applied to the 2000 UN projected population to estimate the number of childhood deaths due to unintentional injuries. RESULTS: Unintentional injuries are estimated to cause 389,000 annual child deaths in South Asia. This premature mortality results in the annual loss of 74 healthy life years (HeaLYs) per 1000 population. CONCLUSION: The current burden of childhood injuries in South Asia is unacceptably high and calls for efforts from all sectors involved in research, policy and funding to not only assess the impact of childhood injuries but to strengthen the health systems to stem this preventable loss of healthy life.

Informed consent and collaborative research: perspectives from the developing world.

INTRODUCTION: Informed consent has been recognized as an important component of research protocols and procedures of disclosure and consent in collaborative research have been criticized, as they may not be in keeping with cultural norms of developing countries. This study, which is part of a larger project funded by the United States National Bioethics Advisory Commission, explores the opinions of developing country researchers regarding informed consent in collaborative research. METHODS: A survey of developing country researchers, involved in human subject research, was conducted by distributing a questionnaire with 169 questions, which included questions relating to informed consent. In addition, six focus group discussions, eight in-depth interviews and 78 responses to open-ended questions in the questionnaire provided qualitative data. RESULTS: 203 surveys were considered complete and were included in the analysis. Written consent was not used by nearly 40% of the researchers in their most recent studies. A large proportion of respondents recommended that human subject regulations should allow more flexibility in ways of documenting informed consent. 84% of researchers agreed that a mechanism to measure understanding should be incorporated in research studies as part of the process of informed consent. DISCUSSION: This paper is an empirical step in highlighting the ethical issues concerning disclosure. Health researchers in developing countries are well aware of the importance of consent in health research, and equally value the significance of educating human subjects regarding study protocols and associated risks and benefits. However, respondents emphasize the need for modifying ethical regulations in collaborative research.

Death from drowning: defining a new challenge for child survival in Bangladesh.

The study focuses on children less than 5 years old and explores the epidemiological profile and correlates of drowning as a challenge to child survival in Bangladesh. Two data sources from Bangladesh, a cohort of 8,070 children followed for 2 years in a rural area and a nation-wide survey conducted in 1996-97 have been used. In addition, a systematic review of the literature has been conducted spanning the past two decades for analysis of drowning in children. Seventy drowning deaths were reported in the cohort and 726 deaths were reported in the national survey. Verbal autopsy and semi-structured interviews were conducted on all deaths. Drowning accounted for 43% of deaths in the cohort and 20% of deaths in 1-4-year-old children in the national survey. Most drowning deaths were in 12-23 month old children from falling into ditches and ponds. Communities provided valuable insights on possible interventions to reduce deaths due to drowning. Drowning is a newly recognized challenge for Bangladesh. Considerable research and programmatic work is required to understand the nature of the problem and develop appropriate interventions. This paper calls on aid agencies to create opportunities for drowning research and action in their work plans for the country.

The burden of disease from neonatal mortality: a review of South Asia and Sub-Saharan Africa.

OBJECTIVE: To assess the burden of neonatal mortality in two developing regions. DESIGN: Review of secondary data collated through literature review. SETTING: Community and facility based studies and national health surveys. POPULATION: Neonatal (<28 days) population of South Asia and Sub-Saharan Africa. METHODS: Data on neonatal mortality were gathered from peer-reviewed literature, reports of the Demographic and Health Surveys and websites of country-based organisations. The base year for this study is 1995. For each country, a weighted mean neonatal mortality rate was calculated and the total number of neonatal deaths estimated. Country data were summarised over each region to estimate annual regional neonatal deaths and rates. The burden of disease from neonatal mortality was determined using a summary measure of health--healthy life years. MAIN OUTCOME MEASURES: Numbers of deaths and healthy life years (HeaLYs). RESULTS: Neonatal mortality rate for South Asia ranged from 41.9 to 56.9 per 1000 live births for 1995. Sri Lanka was an exception with a neonatal mortality rate between 16.3 and 18.6 per 1000 live births. The estimated regional neonatal mortality rate for South Asia was 46.27 per 1000 live births for 1995. There was a significant lack of data from Sub-Saharan Africa, resulting in highly variable neonatal mortality rates, ranging from 13 per 1000 live births in Kenya to 108 per 1000 live births in Senegal. The mean regional neonatal mortality for Sub-Saharan Africa for 1995 was estimated at 38.8 per 1000 live births. CONCLUSION: The burden of neonatal mortality in only these two regions of the developing world represents more than 2 million annual deaths. A call for greater investments in neonatal research and health programs is a logical extension to this review of evidence.
