Headache Characteristics and Risk Factors Among Healthcare Providers in Al-Ahsa, Saudi Arabia.

Introduction Headache is a considerable factor in decreased productivity and work efficiency. This study aims to measure the characteristics of headaches and the risk factors among healthcare providers in Al-Ahsa, Saudi Arabia. Methods This cross-sectional study included 353 healthcare providers from Al-Alhsa, Saudi Arabia. An online questionnaire was conducted to assess the demographic and occupational characteristics, headaches, numerous factors such as smoking, caffeine intake, physical activity, and medical conditions to determine their associations with headaches, as well as the impact of headaches on productivity. Results Among participants who reported headaches, 15.6% and 4.5% had been previously diagnosed with tension headaches and migraines, respectively. The mean duration of headaches was 7.09±18.16 hours; 38.5% of headaches were throbbing in nature, while 61.5% were pressing. The headache was on one side in 51.6% and accompanied by nausea and vomiting in 41.1% and 24.1%, respectively. Moreover, 53% and 41.9% experienced worsening of headaches by exercise and light, respectively. Tension headaches occurred more in older healthcare providers (P <0.05) and those who reported working night shifts (P=0.002). Healthcare providers with tension headaches reported having an intrusive leader and violence at work (P=0.038 and P=0.013, respectively). Caffeine consumption, emotional stress, and using oral contraceptive pills (OCP) were significantly correlated with migraine (P=0.023, P=0.017, and P=0.004, respectively). The reported headache affected the productivity of 62.59% of individuals. Conclusions Headache is common among healthcare providers in Al-Ahsa, Saudi Arabia. The study indicates that tension headache is associated with aging, night shifts, having an intrusive leader, and violence at work. In contrast, migraine is correlated with caffeine consumption, emotional stress, and OCP use. The productivity of healthcare providers is affected negatively by headaches.

Bridge to Better Care: Investigating Transient Ischemic Attack (TIA) Management Expertise Among Primary Healthcare Providers in Al-Ahsa, Saudi Arabia.

Introduction Transient ischemic attacks (TIAs) are brief episodes of neurological impairment caused by reduced blood flow to the brain, spinal cord, or retina, typically lasting under an hour. Recent advances in neuroimaging suggest that some TIAs may actually be small strokes with resolved symptoms. This study focuses on assessing the knowledge and management of TIAs among primary care physicians and nurses in Al-Ahsa, Saudi Arabia. Methodology This is a cross-sectional study, conducted in Al-Ahsa, Saudi Arabia, during the period July to August 2023. Data were collected using an electronic questionnaire and was analyzed using IBM SPSS Statistics for Windows, version 27.0.1 (released 2020, IBM Corp., Armonk, New York, United States). Results Among the participants, 64.0% correctly identified TIA as an ischemic neurological deficit. However, only 20.2% provided correct responses for all TIA symptoms. Regarding diagnostic tests, 47.4% acknowledged the need for neuroimaging immediately after TIA, while 17.5% recognized the importance of ultrasonography of the supra-aortic trunks. In terms of TIA management, 38.6% preferred referral to the emergency service, and 41.2% correctly perceived the risk of TIA recurrence as similar to that of established cerebral ischemic stroke. Significant disparities were observed in the recognition of TIA symptoms, with physicians outperforming nurses, particularly in identifying motor deficits (82.4% vs. 65.2%) and speech alterations (86.8% vs. 76.1%, p = 0.004). However, nurses exhibited better knowledge in recognizing the need for a neuroimaging test (48.5% vs. 45.7%, p = 0.849) and the urgency of conducting a transcranial Doppler (TCD) (19.1% vs. 23.9%, p = 0.641). Conclusion A considerable proportion of healthcare providers demonstrate a good understanding of TIA definition and management. However, the lack of significant predictors for good knowledge and attitude suggests the need for more comprehensive strategies to enhance TIA management expertise across healthcare professionals.

Improving tear ferning patterns collected from goats and camels after adding various electrolyte solutions.

BACKGROUND: Good quality of tear film is essential for healthy vision in both animals and humans. Therefore, improving the quality of tears through the addition of electrolytes is important. OBJECTIVES: To assess the effect of adding various electrolyte solutions on tear ferning (TF) patterns collected from goats and camels. MATERIAL AND METHODS: Tear samples (20 ƒÊL) were collected from 5 goats (2 males and 3 females; 3.4 }1.6 years) and 5 camels (2 males and 3 females; 4.0 }1.1 years) using microcapillary tubes. A tear sample (0.5 ƒÊL) from each animal was mixed with various volumes (0.5.5 ƒÊL) of each electrolyte solution to produce homogenous mixtures. A sample (1 ƒÊL) of each mixture was dried on a microscopic glass at 22°C with a humidity .40%. The obtained TF pattern was observed, graded and compared with those obtained for the corresponding pure tear samples. The effect of dilution using purified water on the TF patterns of animals was also tested. RESULTS: The TF grades of animals were generally enhanced when mixed with electrolyte solutions. Specifically, the TF grade for tears collected from a goat was improved from 1.4 to 0.7 and to 0.8 when magnesium chloride hexahydrate and calcium chloride were added, respectively. Similarly, the TF grade for tears collected from a camel was improved from 1.8 to 0.9 and to 1.1, when calcium chloride and sodium dihydrogen phosphate solutions were added, respectively. CONCLUSIONS: The TF grades of tears collected from both goats and camels were improved after adding electrolyte solutions, and they were most remarkably improved when divalent electrolyte solutions were added, followed by the hydrogenated electrolyte.

Effect of Refresh Plus® preservative-free lubricant eyedrops on tear ferning patterns in dry eye and normal eye subjects.

PURPOSE: To evaluate the tear ferning patterns in dry eye and normal eye subjects in the 3 hours following application of Refresh Plus® preservative-free lubricant eyedrops. METHODS: Thirty men with dry eye (mean age 22.14±2.34 years) and 30 age-matched men with normal eyes (mean age 23.91±3.24 years) were enrolled. Eyes were classified as normal or dry based on their Ocular Surface Disease Index score, tear meniscus height, and noninvasive tear breakup time. The tear ferning test was performed before and 30, 60, 120, and 180 minutes after application of a Refresh Plus eyedrop into the right eye in each subject. RESULTS: There was a significant change in tear ferning grade after application of Refresh Plus eyedrops (P=0.02, Wilcoxon test) in the group with dry eye, but not in the normal eye group (P=0.19, Wilcoxon test). The correlation of tear ferning grade was moderate (r=0.484, P=0.049) at 60 minutes after application of the eyedrops and strong at 120 minutes (r=0.560, P=0.019) and 180 minutes (r=0.726, P=0.001). There was also a strong correlation (r=0.865, P=0.001) between tear ferning grades obtained 120 and 180 minutes after application. In the normal eye group, there was a moderate (r=0.407, P=0.029) correlation between tear ferning grades obtained before and 60 minutes after application of the eyedrops. There was also a strong correlation (r=0.532, P=0.003) between tear ferning grades obtained 120 and 180 minutes after application. CONCLUSION: Tear ferning patterns improved significantly after application of Refresh Plus preservative-free lubricant eyedrops in subjects with dry eye. Artificial tears containing sodium carboxymethylcellulose, such as Refresh Plus, can be used to improve tear ferning patterns in dry eye for at least 3 hours.

A comparative study of the quality of non-stimulated and stimulated tears in normal eye male subjects using the tear ferning test.

PURPOSE: To evaluate and compare the tear ferning patterns of non-stimulated and stimulated tears in normal eye male subjects using the tear ferning test. METHODS: Thirty-five male subjects aged 20-38 years with normal eyes were enrolled in the study. Subjects with dry eye or with a risk factor for eye dryness (eg, recent ocular surgery, contact-lens wearers, smokers, anemic, diabetes, and thyroid gland problems) were excluded from the study. Dry eye subjects were excluded based on the ocular surface diseases index scores, non-invasive tear break-up time, and tear meniscus height measurements from the right and left eyes. A tear sample was collected from both eyes in each subject to perform the tear ferning test for non-stimulated tears. After 10 mins, the tears were stimulated using a Schirmer strip, a tear sample was collected from both eyes in each participant, the tear ferning test was performed, and the ferns were graded based on the five-point tear ferning grading scale. RESULTS: The average tear ferning grade [median (interquartile range)] for non-stimulated tears from the right and left eyes was 0.60 (1.25) and 0.50 (1.31), respectively. For stimulated tears, the average tear ferning grade from the right and left eyes was 0.50 (1.05) and 0.75 (1.25), respectively. There was no significant difference in the tear ferning grades obtained from non-stimulated and stimulated tears (Wilcoxon test, P>0.05). CONCLUSION: This study found no significant difference in the tear ferning patterns obtained from non-stimulated and stimulated tears, or between the tear ferning patterns in the tears collected from the right and left eyes before and after stimulating tears. It seems that there were no changes in the chemical composition of tears before and after stimulation, possibly due to the steady concentration of electrolytes and lipids within the tear film for both non-stimulated and stimulated tears.
