A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world

EVALUATION OF THE OLFACTORY BULB VOLUME ANF OLFACTORY SULCUS DEPTH IN PATIENTS WITH CHRONIC STROKE

AMAÇ: Bu çalışmada, kronik dönemdeki inme geçirmiş hastaların olfaktör bulbus (OB) hacimleri ve olfaktör sulcus (OS) derinliğini değerlendirmek amaçlandı. GEREÇ VE YÖNTEM: Bu çalışma retrospektif ve olgu kontrol çalışması olarak planlandı. Kronik dönemde (>6 ay) inme geçirmiş hastaların OB hacimleri ve OS derinliği ölçümü, manyetik rezonans görüntüleme 1.5-tesla MRG sistemi (Philips MRI Systems, Achieva Release 3.2 Level 2013-10-21, Philips Medical) ile standart kafa coili kullanılarak yapıldı. OB hacim ve OS derinliği ölçümleri, yağ baskılı T2 koronal kesitler kullanılarak yapıldı. İnmeli hastaların verileri sağlıklı kontrol grubu ile karşılaştırıldı. BULGULAR: Çalışmaya, yaş ortalaması 47.7±10.7 yıl olan 45 (21 erkek, 24 kadın) inme geçirmiş hasta ile yaş ortalaması 44.5±8.7 yıl olan 45 (19 erkek-26 kadın) sağlıklı kontrol dahil edildi. İnme grubu ile kontrol grubu karşılaştırıldığında sağ (34.8±10.1 vs. 44.0±7.4 mm3) ve sol OB (34.9±10.0 vs. 49.1±6.2 mm3) hacimlerinin ortalama değerlerinin inme geçirmiş grupta kontrollere göre belirgin olarak azaldığı görüldü. Olfaktör sulkus derinliği ise sağda gruplar arasında değişiklik göstermezken (7.0±0.0 vs. 7.0±0.7 mm) ve solda inmeli grupta daha yüksek bulundu (7.1±0.9 vs. 6.7±0.6 mm). SONUÇ: İnme sonrası kronik dönemdeki hastalarda olfaktör bulbus hacimlerinin azaldığı görüldü.OBJECTIVE: The aim of this study was to evaluate the olfactory bulb (OB) volume and olfactory sulcus (OS) depth in patients with chronic stroke. MATERIAL AND METHODS: This study was designed as a case-control and retrospective study. OB volumes and OB depth of the patients with chronic stroke (>6 months) were measured using a 1.5 tesla MRI machine (Philips MRI Systems, Achieva Release 3.2 Level 2013-10-21, Philips Medical) with a standard head coil. OB volumes and OS depth were measured by using fat suppressed T2 coronal images. The data of the stroke patients were compared to the healthy control subjects. RESULTS: The study included 45 (21 male/24 female) post-stroke patients with the mean age of 47.7±10.7 years and 45 (19 male/26 female) healthy control subjects with the mean age of 44.5±8.7 years. Right (34.8±10.1 vs. 44.0±7.4 mm3) and left (34.9±10.0 vs. 49.1±6.2 mm3) OB volumes were significantly lower in the stroke group than in the control group. Olfactory sulcus depth was similar between the groups on the right side (7.0±0.0 vs. 7.0±0.7 mm), however it was higher in the stroke group on the left side (7.1±0.9 vs. 6.7±0.6 mm). CONCLUSIONS: Patients with chronic stroke seem to have decreased OB volumes compared to the healthy control

Effect of Smoking on Migraine Attack Frequency in Patients with Migraines

Purpose: Smoking and smoke inhalation are known to have negative effects on many diseases, primarily lung diseases. The aim of this study was to examine the effect of smoking on the frequency of migraine attacks in patients. Methods: A total of 82 migraine patients diagnosed in accordance with the revised diagnosis criteria of the International Headache Society were involved in this study. For each patient, we recorded demographic findings, smoking habits, disease duration, attack frequency, headache severity (determined with a visual analogue scale [VAS]), medicine and triggering factors. Those with a migraine attack frequency of less than three times a month were grouped as mild migraine, and those with a greater frequency were grouped as severe migraine. Those that smoked up to and including five cigarettes a day were grouped as mild smokers and those that smoked more than five per day were grouped as severe smokers. The Chi square test was used for parametric distribution. A p-value of< 0.05 was considered significant. Results: Among the 82 migraine patients involved in the study, 13 were male (15.9%) and 69 were female (84.1%). The mean age was 35.85 ± 9.90 years. Migraines with aura were seen in 38 patients (46.3%) and without aura in 44 patients (53.7%). Regarding smoking, 29 patients smoked (35.3%), while 53 did not smoke (64.6%). With patients who smoked, especially in females, the incidence of migraine attacks by 2 or more was higher than those who did not smoke. (57,5%) The mean number of attacks that patients had in a month was 5.45 ± 4.97 and the mean duration of the disease was 11.58 ± 8.43 years. VAS values were 5.85 ± 0.86. A significant relationship was found between smoking and migraine attack frequency in the smoking group (p = 0.002). Conclusion: Migraines are a chronic disease that negatively affects a patient’s quality of life. This study was undertaken to contribute to the relevant literature by showing the effect of smoking on attack frequency in migraines

Thermoluminescence properties of Tb doped Mg2SiO4 after beta irradiation

In this study, we performed Thermoluminescence (TL) experiments to extract the trapping parameters and dosimetric properties of Tb-doped Mg2SiO4 phosphors. Glow peaks located at 193, 270, and 350 degrees C were observed in the glow curve but the peak at 193 degrees C was especially investigated as a dosimetric peak in this study. We also observed an anomalous heating rate effect in which the maximum TL intensity of the glow curve augmented with an increasing heating rate. The computerized glow curve deconvolution (CGCD) method, initial rise (IR) and Hoogenstraaten's method were used to determine the activation energies of associated trapping centers for both BSL-TL 365 nm and IRSL-TL wideband blue filters. The TL characteristics of this phosphor indicate that Mg2SiO4:Tb3+ could be a promising material for dosimetric applications. Efforts should be made to improve the fading behaviour by adding other activators as co-dopants.Cukurova University (FAY-2015-4735
