The investigation of the frequency of COVID-19 in patients with a history of stroke.

Introduction: The emergence of the coronavirus in 2019 became a global epidemic disease. According to the World Health Organization, people with a history of chronic diseases such as brain stroke are among the main groups at risk of contracting COVID-19. Therefore, this study was performed with the aim of the determination amount of the frequency of contracting COVID-19 in stroke patients. Materials and Methods: This descriptive-analytical study was conducted on 100 patients with a history of stroke referred to Imam Hossein Hospital in Tehran (Iran) between 2019 and 2022, which had all the inclusion criteria in the study. The demographic information including (gender, weight, height) and clinical information was collected by a researcher-made questionnaire and analyzed by SPSS version 24 software. Results: The average age of the studied patients was 63 years. Among them, 53 people (53%) were infected with COVID-19. The most of underlying diseases were related to high blood pressure. All cases of stroke in patients with COVID-19 were associated with thrombotic type, and half of the other cases included involvement in large cerebral vessels. Lymphocyte count, CRP, and ESR levels were relatively higher in stroke patients with COVID-19, but there were observed no cases of pleural effusion and pericardial effusion associated with COVID-19 in stroke patients. In all of the patients with COVID-19, pulmonary involvement was observed in the Peripheral/Perihillar area. Discussion and Conclusion: According to the results and data of this research, the probability of infecting COVID-19 is higher in people with a history of stroke, and these patients have more severe strokes and more mortality than stroke patients without contracting COVID-19.

The Impact of COVID-19 on Cancer Recurrence: A Narrative Review.

Severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) continues to be a worldwide healthcare problem. While our knowledge of the interaction of cancer and its management with COVID-19 mortality is gradually evolving, there are still many unanswered questions regarding the impact of COVID-19 on cancer and its prognosis. Several factors activated during COVID-19 have been implicated in tumorigenesis and the development of metastasis. Inflammation, hypoxia, reduced levels of angiotensin converting enzyme 2, elevated levels of Interleukin 6 and some other cytokines that are hallmarks of COVID-19 are capable of inducing tumor relapse and metastasis. On the other hand, there are reports that COVID-19 has been associated with cancer cure. Understanding the interaction between COVID-19 and tumor cells is essential for evaluating the potential long-term risks of COVID-19 in cancer patients, and for scheduling necessary preventive and therapeutic interventions. In this review, we briefly overview the potential impacts that COVID-19 might have on tumorigenesis and cancer relapse, as well as the role that COVID-19 might play in cancer remission and cure.

The Incidence of Deep Vein Thrombosis in Breast Cancer Patients Receiving Outpatient Cancer Therapy in Iran.

BACKGROUND: Venous thromboembolism (VTE) is one of the main causes of mortality in patients with cancer. This study was conducted to assess the incidence of deep vein thrombosis (DVT) in breast cancer patients receiving outpatient cancer therapy. MATERIALS AND METHODS: This multi-center prospective cohort study was conducted on patients with breast cancer, initiating an outpatient chemotherapy regimen in five medical centers in Iran. Eligible patients were enrolled in the study consecutively between January 2013 and January 2015. The primary outcome was lower extremity DVT based on duplex/doppler ultrasonography two months after the first course of chemotherapy (visit 2) and after the end of the course (visit 3). All patients were followed-up from the onset of chemotherapy until the first occurrence of lower extremity DVT, death, or the end of the course. RESULTS: A total of 427 eligible breast cancer patients were recruited in the study, 403 of whom attended at least one follow-up visit. The mean (SD) duration of follow-up was 4 (1.3) months. During the follow-up, only one patient showed DVT on duplex/doppler ultrasonography in visit 2. Therefore, the two-month and overall cumulative incidence risk of DVT was 0.25% (95% CI: 0.00-0.74%). However, the mean D-dimer level showed no significant change (P>0.05). CONCLUSION: Our findings showed the low risk of DVT in breast cancer patients receiving outpatient cancer therapy.

Efficacy of benzydamine oral rinse in prevention and management of radiation-induced oral mucositis: A double-blind placebo-controlled randomized clinical trial.

AIM: Several studies have demonstrated positive effects of benzydamine oral rinse in prevention of radiation-induced oral mucositis. The aim of this study was to assess the efficacy of this medication in reducing the signs and symptoms of oral mucositis in patients receiving radiotherapy for head and neck cancer. METHODS: Fifty-one patients with head and neck carcinoma 2012 received external beam radiotherapy for 5 days/week to total planned cumulative radiotherapy doses of at least 5000 cGy. Patients were randomized to treatment with either benzydamine oral rinse or placebo, initiated the day before radiotherapy and continued for 2 weeks after the end of treatment. Oral cavity was divided into 14 anatomical sites and relevant sites were examined weekly, with a score given to each site based on the degree of mucositis using a 4-point scale, and then a "mean mucositis score" was calculated. RESULTS: Up to the end of third week, two groups did not show any difference in the severity of mucositis. However, by the end of week 4, the mean score of placebo group was more than that of treatment group (1.81 vs 1.27, P=0.001). This trend continued to end of week 7 (1.98 vs 1.43, P=0.001). CONCLUSION: Benzydamine oral rinse can be considered as an effective, safe and well-tolerated medication for prevention of radiation-induced oral mucositis and alleviating its symptoms.

Attitude of cancer patients toward diagnosis disclosure and their preference for clinical decision-making: a national survey.

OBJECTIVES: There is still contradictory evidence on disclosure preferences regarding cancer diagnosis. The aim of this study was to evaluate the preference of cancer patients for knowing the truth about their disease, as well as the factors that might have an impact on these preferences. METHOD: This study was conducted in 11 cancer centers in Iran. A questionnaire was used to collect data, and all patients above 15 years of age who were willing to participate were included in the study. The patients were asked if they were aware of the malignant nature of their disease, and if they came to know about their disease at the time of initial diagnosis, or later. The patients were then asked about the way they looked upon their disease. In the final part of the questionnaire, the participants were asked the level of involvement they prefer to have in making treatment decisions. RESULTS: In total, 1226 patients were enrolled in this study, only 565 (46.7%) of whom were aware of their disease at the time of diagnosis, and 878 (72.7%) at the time of interview, while 980 (85.2%) were willing to receive information about their disease. Patients' awareness was significantly associated with age under 50 years, female gender, having breast, skin or head and neck cancer, and having medical care in Shiraz or Hamadan while it was not associated with the stage or accompanying illness. CONCLUSION: While the majority of Iranian cancer patients prefer to be aware of the nature of their disease and have an active role in treatment decision making, they do not receive this information.

Quality of life among veterans with war-related unilateral lower extremity amputation: a long-term survey in a prosthesis center in Iran.

OBJECTIVE: To determine the factors that have an adverse effect on the long-term health-related quality of life (HRQOL) of veterans who have lost their extremities on the battlefield. DESIGN: Cross-sectional study. SETTING: Tertiary prosthesis center. PARTICIPANTS: One hundred forty-one male Iranian veterans who have sustained unilateral lower extremity amputation during the Iran-Iraq War (1980-1988) were evaluated after an average of 21.6 years (range, 20-27 years) after amputation. INTERVENTION: No intervention. MAIN OUTCOME MEASUREMENTS: Physical and mental HRQOL according to the Short Form-36 (SF-36) Health Survey. A cutoff point to define poor versus good HRQOL was calculated using the first quartile of SF-36 physical and mental component scores. RESULTS: Poor physical HRQOL was positively associated with transfemoral amputation, phantom movement, low back pain, and a lower Barthel Index [odds ratios (ORs): 4.1, 7.8, 9.1, and 0.9, respectively). Poor mental HRQOL was associated with education level lower than high school diploma and the articular pain of the sound leg (OR = 2.9 and 6.5, respectively). Being employed or receiving disability was a factor that had a lower OR to associate with poor mental HRQOL (OR = 0.2). CONCLUSIONS: Alleviation of complaints such as low back pain and articular pain of the sound leg through appropriate medical management, granting facilities for continuing education, and employment are issues that should be considered by authorities and rehabilitative centers to increase HRQOL in amputee veterans.

A very rare case of single coronary artery anomaly, with left anterior descending and left circumflex arteries originating separately from proximal right coronary artery.

Coronary artery anomalies are rare, with the reported prevalence of 0.2% to 1% in routine angiographic studies. Among them, presence of a single coronary artery is one of the rarest anomalies, comprising less than 3% of all coronary anomalies. In this article we report a case of single coronary artery anomaly with left anterior descending and left circumflex arteries arising separately from proximal right coronary artery, and left anterior descending artery reaching atrioventricular sulcus by passing between aortic and pulmonary artery trunci. The patient underwent off-pump coronary artery bypass grafting and is currently symptom-free.
