This cross-sectional study of women was conducted in a deprived area of Papua New Guinea with an estimated infant mortality rate of 133/1000 live births. Mortality patterns derived from birth histories showed that neonatal deaths contribute proportionally more to infant mortality than postneonatal deaths, emphasizing the need for better care at delivery. To examine possible mechanisms for intervention, pregnant women were interviewed to determine patterns of antenatal clinic use, antimalarial drugs and micronutrient supplements given, and how much the women smoked. The results showed that the health system was failing to implement current routine supplementation and prophylaxis regimens, and that there was a need to revise national guidelines. A large proportion of pregnant women smoked during pregnancy, and this behaviour could be a target for future public health campaigns and health worker promotion advice to women.
PIP: A cross-sectional study conducted in 20 randomly selected villages in the impoverished Wosera Subdistrict, East Sepik Province, Papua New Guinea, in 1989 assessed infant mortality, antenatal attendance, and smoking during pregnancy in 1008 women. 60% of respondents had never attended school. The total fertility rate was 5.7/woman. The infant mortality rate was 133/1000 live births. Of the 3074 births reported by respondents, 52 were stillbirths (rate, 17/1000 births). The perinatal mortality rate was 80/1000, the neonatal mortality rate 88/1000, and the postneonatal mortality rate 45/1000. The finding that neonatal deaths contributed proportionately more to infant mortality than postneonatal deaths indicates a need for better care at delivery. Bacterial sepsis related to umbilical infection was common. Of the 109 women pregnant at the time of the survey, only 33 (30%) had been seen at the antenatal clinic. Few of these women were complying with chloroquine treatment (given every 6 weeks). 69% of pregnant women were current smokers of locally cultivated sun-dried tobacco and 68% chewed betel nut during pregnancy. Overall, these findings indicate a need for major changes, including improved implementation of routine supplementation and prophylaxis regimens during pregnancy, health education around the dangers of smoking during pregnancy, improved attendance at antenatal care, and attention to the major causes of infant mortality.
2.A case series of atraumatic nonaneurysmal perimesencephalic subarachnoid hemorrhages triggered during exertion at altitude
Journal of Neurocritical Care 2024;17(2):57-61
Background:
Nonaneurysmal perimesencephalic subarachnoid hemorrhage (NAPH) is a form of subarachnoid hemorrhage (SAH) occurring predominantly in the perimesencephalic region, in the absence of an aneurysm or other source of bleeding on diagnostic angiography. The underlying cause of NAPH remains unclear. Case report: Herein, we describe three patients who developed NAPH during strenuous activity in the absence of trauma after traveling to an altitude of approximately 7,500 feet. The patients were treated conservatively without any residual neurological deficits.
Conclusions
This case series suggests that hypoxia and vigorous exercise could be risk factors for NAPH. Patients traveling to higher altitudes should be counseled to increase their exercise intensity gradually.

The fifth edition of the World Health Organization (WHO) Classification of Central Nervous System (CNS) Tumors was released in 2021, just five years following the updated fourth edition. Advanced molecular testing such as next-generation sequencing, RNA fusion analysis, and DNA methylation profiling has led to more precise grading and classification of pre-existing tumor types as well as the recognition of new ones. Herein, we outline the major updates of the 2021 WHO Classification of CNS tumors, with emphasis on the expanded molecular characterization of CNS tumors.

There is a need recognized by the National Institute of Dental & Craniofacial Research and the National Cancer Institute to advance basic, translational and clinical saliva research. The goal of the Salivaomics Knowledge Base (SKB) is to create a data management system and web resource constructed to support human salivaomics research. To maximize the utility of the SKB for retrieval,integration and analysis of data, we have developed the Saliva Ontology and SDxMart. This article reviews the informatics advances in saliva diagnostics made possible by the Saliva Ontology and SDxMart.

The transradial approach (TRA) is an effective and safe alternative to transfemoral access for diagnostic neuroangiography and craniocervical interventions. While the technical aspects of supraclavicular intervention are well-described, there are little data on the TRA for thoracolumbar angiography and intervention. The authors describe the feasibility of the TRA for preoperative thoracic tumor embolization, emphasizing technique, device selection, navigation, and catheterization of thoracolumbar segmental arteries. This approach extends the benefits of TRA to spinal interventional neuroradiology.
