Prevalence of depression and anxiety among adult patients with multiple sclerosis at Riyadh City,Saudi Arabia

Objectives:To determine the prevalence of depression and anxiety in adult multiple sclerosis patients attending tertiary facilities in Riyadh, Saudi Arabia.Methods:This is a cross-sectional study conducted among MS patients in Riyadh City, Saudi Arabia. A self-administered questionnaire was distributed among MS patients at Prince Sultan Military Medical City in Riyadh, Saudi Arabia between April 2020 and January 2021. The questionnaire consisted of socio-demographic characteristics and the Hospital Anxiety and Depression Scale (HADS). Univariate using Chi-square test and multivariate regression analysis had been performed to determine the factors associated with anxiety and depression among MS patients.Results:A total of 328 MS patients took part in the study. The most prevalent age group was 36–45 years old (38.4%), with over 70% of the participants being females. Anxiety and depression were shown to be prevalent in MS patients at 42.9 percent and 58.8 percent, respectively. According to statistical tests, being less educated and having partial to severe disability was linked to an increased rate of anxiety and depression, whereas being female was more prone to anxiety symptoms but not depression.Conclusion:Depression was more frequent than anxiety. As a result, while assessing psychiatric diseases in the study group, depression/anxiety may be expected to be more frequent amongst those of greater disability.

Multiple sclerosis (MS) is a central nervous system demyelinating disease caused by an immunological response. Depression and anxiety are more common in patients with multiple sclerosis (PWMS) than in the general population, ^1-4 which is a well-known phenomenon. However, we believe that these illnesses are under-recognized in PWMS because several MS symptoms overlap with depression and anxiety, making detection more difficult. Fatigue, sleeplessness, anorexia, memory loss, and concentration problems are all common symptoms of depression, MS, or both. ^5,6 Furthermore, the symptoms of MS might mislead self-report rating scales designed to detect depression and anxiety, resulting in false positives or negatives. ^5,6 Moreover, depression in PWMS can impair their quality of life (QOL), medication adherence, and compliance, worsening their prognosis. ^7-9 Suicidal thoughts and attempts are also common. ^10-13 The hospital Anxiety and Depression Scale is a one-of-a-kind measure for detecting anxiety and depression while taking into account both disorders’ possible confounders, and it has been validated for use in PWMS. ⁶ Depression is a significant mood illness that affects many people. It creates severe symptoms that impact how you feel, think, and handle day-to-day tasks like working, sleeping, and eating. ¹⁴ In PWMS, the lifetime prevalence of depression in up to 50%, ³ compared to 10.8% in the general population. ¹⁵ The cause of depressive disorders in people with MS is unknown. However, it is assumed to be complex, with psychological, social, and neurological aspects - as well as immunologic and genetic factors - all having a part. ¹⁶ Furthermore, depression can have a severe impact on these patients’ health by raising the severity of their symptoms and reducing their compliance with therapy and follow-up, both of which have an impact on their medical costs. ⁹ In addition to a decreased quality of life (QOL), cognitive impairment, and an increased risk of suicide, especially when anxiety is present. ^7,10,11 Furthermore, PWMS have a 10-year lower life expectancy than the general population of the same age. ² Patients, caregivers, and care providers should not underestimate the impact of sadness and anxiety on PWMS. Improved identification, diagnosis, and treatment in medical offices, where people with mood disorders are frequently seen for the first time, can assist to improve these negative outcomes. ¹⁷ Unfortunately, despite convincing evidence of its high incidence, greater influence on prognosis, and quality of life, depression and anxiety are still underdiagnosed and undertreated. ¹³ The goal of this study is to find out how common depression and anxiety are among adult patients with multiple sclerosis in Riyadh, Saudi Arabia. We’ll also see if there’s a link between Hospital Anxiety and Depression Scale (HADS) score and patients’ demographical, socio-educational, and MS-related characteristics, as well as MS duration, Immunomodulatory type, and EDSS scores.     

Investigation of Structural,Physical, and Attenuation Parameters of Glass: TeO2-Bi2O3-B2O3-TiO2-RE2O3 (RE: La,Ce, Sm,Er, and Yb), and Applications Thereof

A novel series of glass, consisting of B₂O₃, Bi₂O₃, TeO₂, and TiO₂ (BBTT) containing rare earth oxide RE₂O₃, where RE is La, Ce, Sm, Er, and Yb, was prepared. We investigated the structural, optical, and gamma attenuation properties of the resultant glass. The optical energy bands, the linear refractive indices, the molar refractions, the metallization criteria, and the optical basicity were all determined for the prepared glass. Furthermore, physical parameters such as the density, the molar volume, the oxygen molar volume, and the oxygen packing density of the prepared glass, were computed. Both the values of density and optical energy of the prepared glass increased in the order of La₂O₃, Ce₂O₃, Sm₂O₃, Er₂O₃, and then Yb₂O₃. In addition, the glass doped with Yb₂O₃ had the lowest refractive index, electronic polarizability, and optical basicity values compared with the other prepared glass. The structures of the prepared glass were investigated by the deconvolution of infrared spectroscopy, which determined that TeO₄, TeO₃, BO₄, BO₃, BiO₆, and TiO₄ units had formed. Furthermore, the structural changes in glass are related to the ratio of the intensity of TeO₄/TeO₃, depending on the type of rare earth. It is also clarified that the resultant glass samples are good attenuators against low-energy radiation, especially those that modified by Yb₂O₃, which exhibited superior shielding efficiency at energies of 622, 1170, and 1330 keV. The optical and gamma ray spectroscopy results of the prepared glass show that it is a good candidate for nonlinear optical fibers, laser solid material, and optical shielding protection.     

Salivary duct carcinoma presenting with vaginal metastasis: case report

Vaginal cancer represents about 1-2% of the genital tract malignancies. Most cases represent metastasis from the cervix, endometrium or colon. Metastasis of salivary duct carcinoma to the vagina has not been previously reported. Salivary duct carcinoma (SDC) is a rare, highly aggressive tumor that most often involves the parotid gland. On presentation, SDC is metastasized to the regional lymph nodes in about 40% of cases. We report a case of metastatic salivary duct carcinoma presenting as a vaginal mass with bleeding. Diagnosis was confirmed by the histological appearance in addition to immunohistochemistry. To our knowledge this is the first reported case of vaginal metastasis from SDC. Small-sized primaries might be ignored by the patient, specially in the older age group, probably due to lack of manifesting symptoms like pain and bleeding. Some cancers, like SDC, have various histologic patterns in different areas of the tumor. Careful examinations of multiple sections, in addition to an immunohistochemical panel, and histologic comparison of all lesions are keys to a correct diagnosis.     

Evaluation of the Radiation Shielding Properties of a Tellurite Glass System Modified with Sodium Oxide

In this study, the X-ray and gamma attenuation characteristics and optical properties of a synthesized tellurite–phosphate–sodium oxide glass system with a composition of (85 − x)TeO₂–10P₂O₅–xNa₂O mol% (where x = 15, 20, and 25) were evaluated. The glass systems we re fabricated by our research group using quenching melt fabrication. The shielding parameters of as-synthesized systems, such as the mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), effective atomic number (Z_eff), half-value layer (HVL), tenth value layer (TVL), mean free path (MFP), and effective electron density (N_eff) in a wide energy range between 15 keV and 15 MeV, were estimated using well-known PHY-X/PSD software and recently developed MIKE software. Herein, the optical parameters of prepared glasses, such as molar volume (V_M), oxygen molar volume (V_O), oxygen packing density (OPD), molar polarizability (αm), molar refractivity (R_m), reflection loss (R_L), and metallization (M), were estimated using MIKE software. Furthermore, the shielding performance of the prepared glasses was compared with that of commonly used standard glass shielding materials. The results show that the incorporation of sodium oxide into the matrix TeO₂/P₂O₅ with an optimum concentration can yield a glass system with good shielding performance as well as good optical and physical properties, especially at low photon energy.     

A randomised trial of nursing interventions supporting recovery of the postmastectomy patient

Aims and objectives. This ABC to recovery study evaluated the combined and separate components of preoperative education and the effectiveness of wearing the Papilla Gown. Background. Surgical removal of the breast may lead to activity limitation, self‐image issues, discomfort and later complication of lymphoedema. Design. This study used experimental and longitudinal design. Methods. One hundred and forty‐five women undergoing mastectomies for stages two and three breast cancer were randomised into four groups: education and Papilla Gown, education only, gown only and control. The outcomes of activity (A), body image (B), comfort (C), knowledge and lymphoedema were assessed at baseline and/or 1 week and 6 months using three measures. All 145 participants completed the study questionnaires at first two measures, and forty‐six of these participants completed the questionnaires at 6 months postoperatively. The setting for the study included two clinics and hospitals. To examine statistical significance at each time point after surgery, 2‐way anova s were performed on ABC, knowledge and tape measurement to see whether there were any statistically significant differences between the four groups. All reported p‐values are two sided. All statistical analyses were performed using sas 9.2 for Windows. Results. The mean age of the sample was 55 years. The study revealed that women who received the combined intervention demonstrated greater activity. Women who wore the gown only had a greater comfort level and decreased lymphoedema. Women that received preoperative education experienced increased knowledge. Conclusions. Outcomes suggest that the combined intervention (ABCs to recovery) can improve recovery following mastectomy. Relevance to clinical practice. The results will be used to further modify the intervention and to increase awareness of nurse practitioners and other healthcare professionals of the specific needs of postmastectomy patients.
