Abstract Background: Retinal vein occlusion (RVO) is a common retinal vascular disease that causes a loss of vision. Therefore, we investigated whether there is seasonal variation in the onset of RVO, to examine the possibility of preventing it.Methods: Patients with RVO who were treated at the Juntendo University Urayasu Hospital between April 2013 and March 2017 were included in this retrospective study. The season in which the RVO occurred was recorded for each case, and the cases were grouped into six 2-month periods based on the month of RVO, and classified by age, sex and hypertension status. The frequency of occurrence of RVO across seasons was compared using a chi-squared test.Results: A total of 348 patients with RVO presented during the study period, with information regarding the date of RVO onset. The cohort of 348 consisted of 167 males and 181 females who, overall, had a mean age of 64.0 years (range 17–96 years). The highest incidence of RVO onset was during January/February, with the lowest incidence during July/August. Patient age, sex and hypertension status did not influence the results.Conclusions: The seasonal onset of RVO tended to be higher in January/February and May/June, and lower in July/August. These findings suggest that eyecare professionals should be more vigilant in watching for the occurrence of RVO during winter and the rainy season, regardless of the patient’s sex, age or hypertension status.

Dietitians as healthcare professionals could decrease their quality of life during the SARS-COV-2 pandemic period; therefore, this study aimed to compare Brazilian dietitians’ perceptions of quality of life before and during the pandemic. This nationwide cross-sectional research aimed to evaluate Brazilian dietitians’ quality of life before and in the course of the COVID-19 pandemic, using a previously validated self-administered instrument WHO-QOL-BREF in Brazilian-Portuguese. The questionnaire was composed of 26 items (four domains) to evaluate life quality (physical, psychological, social relationship, and environment). The questionnaire also presented some sociodemographic variables and three questions about the COVID-19 pandemic. It was applied using GoogleForms® platform (Google LLC, Mountain View, CA, USA). For the statistical analysis of data, Paired T-test, Chi-squared test, and Analysis of Variance were used. A total of 1290 Brazilian dietitians replied to the instrument. Comparing quality of life (QoL) before SARS-COV-2 (3.83 ± 0.59) and during the pandemic (3.36 ± 0.66), data was statistically different. Comparing prior and in the course of the COVID-19 pandemic, all variables and domains presented statistical differences (better before the pandemic period). Among Brazilian dietitians, the psychological health domain was the most affected. The Sars-Cov-2 pandemic negatively impacted the QoL of Brazilian dietitians since health professionals face changes in their lives because of work.

Summary Introduction: Patients who are treating cancer have often used alternative therapies. In the internet era, information can be broadcasted widely, and this happened with phosphoethanolamine in Brazil, where this substance was claimed by the population to be the "cure for cancer." Method: This is a cross-sectional study developed by the Brazilian Society of Clinical Oncology (SBOC). An objectively structured questionnaire was sent by e-mail and SMS to active MDs members of the SBOC. Descriptive statistics was used to evaluate the data. Statistical significance between the variables was tested by Pearson's Chi-squared test (p<0.05 was considered significance). Results: The survey was sent to 1,072 oncologists, and 398 (37.1%) answered at least part of it. One hundred and fifteen (28.9%) had followed patients who had used phosphoethanolamine. Among these, 14 (12.2%) observed adverse events and four (3.5%) attributed clinical benefit to the substance. Most of the oncologists (n=331; 83.2%) believe that it should only be used as part of a clinical trial protocol. Most physicians did not recommend this drug to their patients (n=311; 78.1%). Oncologists in Southeast, South and Midwest Brazil were more likely to have patients taking the drug compared to the Northern and Northeastern regions. Conclusion: This is the first survey to assess the opinion and experience of oncologists about this alternative therapy. Most oncologists in Brazil do not believe that synthetic phosphoethanolamine is active in cancer treatment, do not recommend its use without proper evaluation, and state that it should only be available to patients in the context of clinical trials.

Abstract Objectives  The diagnosis and treatment of patients with sleep disorders are the most challenging issues in dentistry. The aim of this study was to assess the knowledge among dental interns in Northern Jordan about sleep medicine and sleep disorders. Methods This cross-sectional study was performed using the Assessment of Sleep Knowledge in Medical Education (ASKME) questionnaire. The questionnaire was given to 88 dental interns (52 females and 36 males) in Northern Jordan. Chi-squared test was utilized for data analysis. Results The mean score of the ASKME questionnaire was 12 out of 30 (40%). The majority of dental interns (88.6%) correctly answered ≤ 50% of the questions. No association was found between gender and score results. Conclusions Dental interns in Northern Jordan have a low level of knowledge about sleep medicine and sleep disorders. Dental faculties should provide courses related to sleep medicine throughout undergraduate education.

Objective. The aim of this work was to define the prevalence of back pain in children and youth aged 10–19 from the southeast of Poland.Material and Methods. The cross-sectional study included 1089 students (547 girls and 542 boys) aged 10–19. The prevalence of back pain, its intensity, location, and situations in which it occurred were assessed with a questionnaire.Results. Among 1089 respondents, 830 (76.2%) admitted that they had experienced back pain at various frequencies within the year preceding the study. Back pain was located mainly in the lumbar segment (74.8%). Mild pains were dominant, which was declared by 44.7% of the respondents. Girls experienced back pain significantly more frequently than boys (52.2% versus 47.8%,P<0.05).Conclusions. The research revealed that back pain is a common phenomenon. The prevalence of back pain in children and youth living in southeast Poland is similar to the frequency of occurrence of such complaints occurring in peers in other countries. It seems significant to monitor the remaining regions of Poland in order to define the scale of the problem and to look for the risk factors of back pain in children and youth to undertake efficient prophylactic actions.

AbstractObjective:To explore whether the incidence of post-tonsillectomy haemorrhage requiring a return to theatre demonstrates a monthly or seasonal variation.Design:Retrospective, cross-sectional study including all 256 799 tonsillectomies performed between April 2000 and March 2005 in NHS trusts in England.Outcome measures:Return-to-theatre rates for each calendar month and each three-month ‘season’, over the five-year study period.Results:A statistically significant association was found between the calendar month and the proportion of patients requiring a return to theatre for post-tonsillectomy haemorrhage (p=0.005). There was a bimodal seasonal distribution peaking in the winter and summer months, with winter rates significantly higher than spring rates (p=0.0104).Conclusions:The incidence of severe post-tonsillectomy haemorrhage showed monthly and seasonal variations. This is clearly a multi-factorial problem. However, in patients at high risk of bleeding or of the complications of bleeding, consideration should be given to performing tonsillectomy at a time of year of lower incidence.

ABSTRACT Introduction The increased number of people who choose running as a form of exercise has been associated with a higher prevalence of musculoskeletal injuries. Objectives To determine the prevalence and the factors that could be correlated with injuries among amateur runners in Recife, in the State of Pernambuco (PE), Brazil. Methods An observational, cross-sectional study, in which 300 (three hundred) amateur runners answered a social demographic questionnaire, as well as questions about training characteristics, footstrike and landing pattern, and history of running injuries. The data were analyzed by descriptive statistics, the student-t test to compare means, and the Chi-squared to compare prevalences. Results The prevalence of injuries amongst runners in Recife-PE was 58.5% (n= 175), the knee being the most commonly injured site (37.3%). In both groups - runners with and without injuries – there was a higher number of male runners, with 72.4% and 72.6% respectively. There was no difference in relation to the weekly frequency of running between the groups (p<0.63). However, runners with a history of injuries ran around 7 kmh a week more than the runners without injuries (p<0.03). A neutral footstrike (F=0.87; p=0.99) and hindfoot landing (F=4.13; p=0.90) were the most reported running patterns in both groups. It was found that wear was the main criterion used for changing running shoes in both groups (F = 8.35, p = 0.4). Conclusion There was a high prevalence of musculoskeletal injuries among amateur runners in Recife-PE. Among the factors associated with the injuries, one variable was significant: a higher weekly volume of training. Level of evidence II; Study type: Cross-sectional study.

Abstract Background Headache is one of the most disturbing complaints worldwide, negatively impacting social and regular life activities. In the background of stressful life in medical schools, adding to the stressful situation in Palestine, a developing country under occupation, this study investigated the prevalence and clinical characteristics of migraines and tension- type headaches among medical students from the Palestinian Universities in West Bank and Gaza. Methods A questionnaire-based cross-sectional study was conducted on all Palestinian Medical Students. Students were diagnosed based on ICHD-3 criteria. Demographic characteristics were compared by gender for each type of headache. Frequency, percentage, and mean ± SD. Pearson’s chi-squared test, independent t-test, and one-way ANOVA were used where needed. P-value < 0.05 was considered significant. Results The study included 806 medical students; 476 (59.0%) of them were female. TTH and migraine’s prevalence was 59.8 and 22%, respectively, with a higher prevalence among basic year students. The female to male ratio was 1:0.6 for both types of headaches. Sleep deprivation, physical activities, and altered sleep patterns were reported as the top triggering factors. Conclusions The results demonstrate that the prevalence of both subtypes’ primary headache is high among Palestinian medical students, with a higher prevalence among basic year students. The study also showed that these findings are higher than other studies among medical students in other countries.
