Objectives: This study aimed to compare coping strategies among students with chronic medical illnesses in contrast to healthy students to understand their behaviours in response to stressful situations. |
Methods: This comparative cross-sectional study was conducted between September and December 2019 and included students attending nine colleges at Sultan Qaboos University (SQU), Muscat, Oman. Data were collected and compared between students with chronic medical illnesses and those who were healthy. A validated Arabic... |
Results: A total of 405 students participated in the study; of these, 229 (56.5%) were male and 176 (43.5%) were female. Overall, 113 students (28%) had a chronic medical illness. Positive coping strategies named religion, acceptance planning, and active coping were the most frequently reported coping strategies among ... |

BACKGROUND |
Migraine is a prevalent and chronic disease associated with high rates of disability and significant financial and socioeconomic burden. Current acute treatments for migraine attacks include both migraine-specific (e.g., triptans, ergotamines) and nonspecific (e.g., nonsteroidal anti-inflammatory drugs) medications; ho... |
OBJECTIVES |
The authors sought to characterize the nature and drivers of unmet treatment needs in the acute treatment of migraine attacks and describe emerging migraine-specific treatments, that is, calcitonin gene-related peptide (CGRP) receptor antagonists. |
DATA SOURCES |
PubMed searches were conducted using search terms for studies of unmet migraine treatment needs and CGRP receptor antagonists. Additionally, studies presented at recent headache-focused congresses were included. |
CONCLUSIONS |
Forty percent of people with migraine report at least 1 unmet treatment need. Many people are unable to use migraine-specific or nonspecific agents because of contraindications, precautions, and tolerability issues. Disease burden (disability, headache severity/frequency) remains high even in those receiving migraine-s... |
IMPLICATIONS FOR PRACTICE |
The availability and use of CGRP receptor antagonists may help reduce the extent of unmet needs in the treatment of migraine attacks, resulting in more patients receiving treatment and better outcomes for people with migraine. Nurse practitioners are well positioned to increase rates of migraine diagnosis/treatment (an... |
