Intention and practice on personal preventive measures against COVID-19 among older adults in the Kingdom of Saudi Arabia: an epidemiological study using the Theory of Planned Behaviour.

Introduction: Older adults aged 65 years and above are among the most vulnerable to adverse outcomes and death following a COVID-19 infection. The weekly epidemiological updates by the World Health Organisation show that the continued emergence of concerning subtypes of the virus indicates that the pandemic remains a public health concern and the public should continue to comply with personal preventive measures (PPMs). This study applies the Theory of Planned Behaviour (TPB) which is rooted in the field of Public Health, Epidemiology, and Preventive Medicine to Saudi older adults to predict their health behaviour. Methods: This behavioural epidemiological study recruited older adult participants aged 65 years of age and above. A tool which consisted of sociodemographic and health-related questions, as well as questions regarding the components of the TPB, namely, Attitude, Subjective Norm, Perceived Behavioural Control was used. Bivariate analyses, followed by unadjusted and adjusted multivariable logistic regression analyses were performed to derive odds ratios and 95% confidence intervals. Results: The total number of participants was 502. The mean age was 70.34 years, with similar distributions between males and females. In total, 52.2% intended to practice PPMs, whereas only 48% had a good practice. Also, 56% had a favourable Attitude towards PPMs, 61.4% had a positive Subjective Norm and 39.8% had perceived they had a high control over their behaviour. Females, and high educational status were predictors for high intention to practice PPMs (OR = 1.59, 95% CI = 1.01-2.52 and OR = 2.72, 95% CI = 1.44-5.16 respectively). Further predictors included Attitudes, Subjective Norm and Perceived Behavioural Control. Results also show that intention to practice was significantly associated with a lower odd of practicing PPMs (OR = 0.06, 95% CI = 0.04-0.10). Conclusion: Current findings highlight the need to continue with public health efforts targeting vulnerable older adults. Also, the fact that intention negatively predicted practice highlights the need for further behavioural epidemiological studies addressing the intention-behaviour gap.

Multidisciplinary Approach for a Rare Metastatic Low-Grade Endometrial Stromal Sarcoma to the Inferior Vena Cava and the Right Atrium.

Endometrial stromal sarcoma (ESS) is a rare, malignant tumor of the endometrium. Low-grade endometrial stromal sarcoma (LG-ESS) is a less aggressive subtype of ESS that rarely metastasizes to the heart and large blood vessels. In the present study, we report a case of recurrent LG-ESS after treating the initial mass in the uterus six years ago in a 49-year-old female who presented with a four-month history of dyspnea and easy fatigability. Investigations revealed a right pulmonary embolism, suspicious right psoas muscle mass, and a large inferior vena cava (IVC) thrombus. One month later, she presented with multiple gastrointestinal symptoms and weight loss. Investigations then showed the development of a new right atrial mass, infra-diaphragmatic metastatic lymphadenopathy, progression of the presacral soft tissue component, invasion of the ileal bowel loop, and a tumoral thrombus in the IVC besides new metastatic lymphadenopathy and pulmonary metastasis. Therefore, a multidisciplinary team, which had a crucial role in this complicated case, decided to commence chemotherapy treatment. Such an unusual aggressive metastatic course of LG-ESS is limited in the literature; herein, we recognize a rarely documented disease.
