بررسی ارتباط استفاده از شبکه‌های اجتماعی تلفن همراه با سلامت روان در کارکنان ستادی دانشگاه علوم پزشکی گلستان

Background and Aims: Studies have shown that excessive use of social networks may cause mental disorders. This study was conducted to elucidate the relationship between the use of cell phone’s social networks and mental health. Materials and Methods: A cross-sectional study was conducted in 2022, in which totally 250 staff members of Golestan University of Medical Sciences participated. Proportional random stratified sampling method was used. The data collection tool was a checklist of demographic variables. Additionally, valid and reliable questionnaires on the use of mobile cell phone’s social networks and mental health were exploited. The data was analyzed with the help of descriptive and inferential statistics in SPSS software (v.24) and statistical tests were considered significant at P<0.05. Compliance with ethical considerations was considered in all stages of the study implementation. Results: The average age of employees was 41.07±6.8 years and their average work experience was 15.04±6.93 years. About 56.8% of participants were women and the rest were men. WhatsApp was the most commonly used social network by study participants (44.8 percent). The average score of using mobile social network and mental health was 21.81±5.74 and 35.17±6.20 respectively. The use of social networks revealed a statistically significant association with the total score of mental health (P < 0.001). Conclusion: The amount of social networks use was reported at a low level and the mental health of employees needs serious interventions. Considering the existence of a relationship between the engagement in social networks and mental health, the controlled use of social networks can prevent employees' mental health from being compromised.زمینه و اهداف: مطالعات نشان داده‌اند، استفاده زیاد از شبکه‌های اجتماعی می‌تواند باعث بروز اختلالات روانی شود. این مطالعه با هدف تعیین ارتباط بین میزان استفاده از شبکه‌های اجتماعی تلفن همراه با سلامت روان انجام شد. مواد و روش‌ها: یک مطالعه مقطعی در سال ۱۴۰۱ انجام شد. ۲۵۰ نفر از كاركنان ستادی دانشگاه علوم پزشکی گلستان در مطالعه شرکت نمودند. روش نمونه‌گیری به روش طبقه‌ای تصادفی متناسب بود. ابزار جمع‌آوری داده‌ها، چک لیست متغیرهای جمعیت‌شناختی و همچنین، پرسشنامه‌های روا و پایا شده ميزان استفاده از شبكه‌هاي اجتماعي تلفن همراه و سلامت روان بودند. داده‌ها به کمک آمار توصیفی و استنباطی در نرم‌افزار SPSS نسخه 24 و سطح معناداری 0/05 تحلیل شد. رعایت ملاحظات اخلاقی در تمام مراحل اجرای مطالعه درنظر گرفته شد. یافته‌ها: میانگین سنی کارکنان 6/8 ±41/07 سال و میانگین سابقه کار آنها 6/93 ±15/04 سال بود. 56/8 درصد زن و بقيه مرد بودند. بیشترین شبکه اجتماعی مورد استفاده کاربران، واتس آپ (44/8 درصد) بود. میانگین نمره استفاده از شبکه اجتماعی و سلامت روان به ترتیب 5/74 ±21/81 و 6/2 ±35/17 بود. ميزان استفاده از شبکه‌های اجتماعی با نمره کل سلامت روان ارتباط معناداری داشت (P<0/001). نتیجه‌گیری: میزان استفاده از شبکه‌های اجتماعی در سطح پایینی گزارش شد و سلامت روان کارکنان نیازمند مداخلات جدی است. با توجه به وجود ارتباط بین میزان استفاده از شبکه‌های اجتماعی با سلامت روان، استفاده منطقی و کنترل شده شبکه‌های اجتماعی می‌تواند مانع به مخاطره افتادن سلامت روان کارکنان گردد

Trigeminal Neuralgia as the First Clinical Manifestation of Anti-Hu Paraneoplastic Syndrome Induced by a Borderline Ovarian Mucinous Tumor

Paraneoplastic neurologic syndrome (PNS) is an uncommon manifestation of cancer that is not caused by the tumor or metastasis. Trigeminal neuralgia (TN) is an initial symptom of this disease, but it has rarely been reported in the literature. Here, we report the case of a 76-year-old woman who presented with classic TN, followed by limbic encephalitis due to an underlying ovarian intestinal-type mucinous borderline tumor, with the presence of anti-Hu antibodies. She recovered quickly after removal of the tumor and was essentially free of symptoms 2 weeks after surgery. Because PNS precedes the tumor in approximately 60% of cases, its rapid detection and treatment are crucial. Therefore, we propose that PNS be considered during the management of TN when brain imaging is normal, as it is followed by other central and/or peripheral neurological manifestations as well as the presence of systemic symptoms such as anemia, fatigability, loss of appetite, or weight loss

Role of nitrogen doping at the surface of titanium nitride thin films towards capacitive charge storage enhancement

International audienceWe recently reported an impressive cycling stability (over 20,000 cycles) of titanium nitride (TiN) electrodes with high specific capacitance. It is anticipated that nitrogen (beta-N) doping in the oxidized surface of TiN film plays a crucial role in charge storage mechanism and stability of this material. In this work, we offer an evidence on the effect of beta-N doping on improvement in specific capacitance of vacuum annealed TiN thin films. The annealing of the TiN films leads to the diffusion of the excess beta-N from sub-surface to oxidized TiN film surface without further oxidation of the electrode surface. We demonstrate an increase in the TiN areal capacitance upon an increase in the amount of beta-N dopant. The areal capacitance of the annealed films was enhanced by 3-fold (8.2 mF cm(-2) in K2SO4 aqueous electrolyte) without sacrificing the cycling stability of the electrodes after more than 10,000 consecutive charge/discharge cycles.
