MATERIALS AND METHODS: The authors conducted a literature search in four databases (Scopus, Web of Science, Science Direct, and IEEE Xplore) and completed it in December 2022. Articles that do not directly address the application of drones for surveillance and control of mosquito breeding sites were excluded.
RESULTS: The initial search using the keywords yielded 623 documents. After screening abstracts and reviewing the full text, only 17 articles met the inclusion criteria. Most of the studies were in the proof-of-concept stage. Many studies have also incorporated drone technologies and machine learning techniques into surveillance efforts. The authors have highlighted seven key issues related to the operational aspects of using drones. Those are hardware, software, law and regulation, operating time, expertise, geography, and community involvement.
CONCLUSION: With rapid developments in drone technologies and machine learning techniques, the viability of drones as surveillance tools can be enhanced, thus effectively responding to global public health concerns.
MATERIALS AND METHODS: We analysed 122 consecutive patients with spontaneous SAH following intracranial aneurysmal and non-aneurysmal information (including patients' pattern characterisation and their possible risk factor association to pre-operative clinical decision and long-term clinical outcome) was documented and analysed.
RESULTS: The main clinical presentations for spontaneous SAH following ruptured intracranial aneurysm and nonaneurysm were headache (77%) and nausea/vomiting (62.3%). The most common sites for SAH following ruptured intracranial aneurysm rupture were the anterior and posterior communicating arteries (57.5%). Hypertension was the most common cause for SAH at 64.8%. It was found 26.2% (n=32) out of the 122 patients developed CV and DCI. The mean day of vasospasm was 6.0 ± 2.8 (range: 1-14 days) Age, length of stay, nausea/vomiting and visual field defect were significantly associated (p<0.05) with vasospasm. Mortality rate was also higher in the CV group compared to the group without CV in both at discharge and at 6 months; 281 versus 278 per 1000 and 312 vs 300 per 1000, respectively.
CONCLUSION: CV and DCI have a significant incidence among local patients with spontaneous SAH following an intracranial aneurysmal and non-aneurysmal rupture and it is associated with substantial morbidity. Prevention, effective monitoring, and early detection are keys to successful management. Regional investigation using a multicentre cohort to analyse mortality and survival rates may aid in improving national resource management of these patients.
