Risk factors associated with long covid syndrome: A retrospective study

Background: Recently, people have recognized the post-acute phase symptoms of the COVID-19. We investigated the long-term symptoms associated with COVID-19, (Long COVID Syndrome), and the risk factors associated with it. Methods: This was a retrospective observational study. All the consecutive adult patients referred to the healthcare facilities anywhere in Fars province from 19 February 2020 until 20 November 2020 were included. All the patients had a confirmed COVID-19 diagnosis. In a phone call to the patients, at least three months after their discharge from the hospital, we obtained their current information. The IBM SPSS Statistics (version 25.0) was used. Pearson Chi square, Fisher’s exact test, t test, and binary logistic regression analysis model were employed. A P value of less than 0.05 was considered to be significant. Results: In total, 4,681 patients were studied, 2915 of whom (62.3%) reported symptoms. The most common symptoms of long COVID syndrome were fatigue, exercise intolerance, walking intolerance, muscle pain, and shortness of breath. Women were more likely to experience long-term COVID syndrome than men (Odds Ratio: 1,268; 95% Confidence Interval: 1,122-1,432; P=0.0001), which was significant. Presentation with respiratory problems at the onset of illness was also significantly associated with long COVID syndrome (Odds Ratio: 1.425; 95% Confidence Interval: 1.177-1.724; P=0.0001). A shorter length of hospital stay was inversely associated with long COVID syndrome (Odds Ratio: 0.953; 95% Confidence Interval: 0.941-0.965; P=0.0001). Conclusion: Long COVID syndrome is a frequent and disabling condition and has significant associations with sex (female), respiratory symptoms at the onset, and the severity of the illness

The Study of Fiber Fines and Its Effects On Optical and Physical Propertie of Newsprint Paper from CMP Pulp

The present study deals with effects of CMP  fines on optical and physical properties of newsprint papers, for which, different batches for CMP fines (0%, 10%. 20%. 30%) of totally 80% pulp  is taken, Where the remaining 20% of imported long fiber pulp was taken as fixed amount . The study focused on surving the effects of CMP fines on optical and physical properties of newsprint paper ,after mixing the pulps and making the handsheets . Generally, the results show the increase in CMP fine amount lead to increase ,Air Resistance and Opacity and decrease Caliper and Roughness, Also that changes in CMP fines has no effect on Brightness

Intervenção educacional com base em modelo para aumentar a atividade física entre adolescentes iranianos

OBJETIVO: Avaliar um programa educacional com base no modelo de promoção da saúde (MPS) e nos estágios de mudança para melhorar a atividade física (AF) entre adolescentes iranianos. MÉTODOS: Este foi um ensaio randomizado controlado com 165 participantes divididos em dois grupos (intervenção/controle). Os dados foram coletados através de questionários de autopreenchimento com base em componentes do MPS (benefícios e barreiras para a ação, autoeficácia, sentimentos em relação ao comportamento, influências interpessoais e situacionais). A escala de estágios de mudança foi utilizada para selecionar participantes aptos (classificados nos estágios de pré-contemplação, contemplação ou preparação) e para avaliar a tendência. Após a coleta dos dados de base, a intervenção foi realizada nos participantes e os dados de acompanhamento foram coletados 3 meses depois. RESULTADOS: Ao todo, 88 meninos e 77 meninas com idade média de 13,99±0,4 participaram do estudo. As diferenças em todos os componentes do MPS, exceto os sentimentos em relação ao comportamento e as influências sociais, foram significantes (p < 0,01) entre os valores de base e de acompanhamento. Comparados aos do grupo de controle, os adolescentes do grupo de intervenção foram categorizados nos estágios de ação (70%) ou preparação (30%) no acompanhamento. A análise de regressão múltipla revelou que preferências concorrentes, normas sociais, modelos sociais (variáveis com p < 0,001) e o compromisso com o plano de ação podem prever consideravelmente o comportamento quanto à AF. O modelo representou 22,5% da variação da AF. CONCLUSÕES: Intervenções educacionais com base nos estágios de mudança podem ter implicações importantes na melhora da AF entre adolescentes em mais componentes do MPS

Factors associated with suicidal ideation among medical residents in Tehran during the COVID-19 pandemic: A multicentric cross-sectional survey.

BackgroundThe mental health of medical residents, challenged by their intensive training, is of utmost concern. In light of reported suicides among Iranian medical residents in 2021, this study investigates the factors behind suicidal ideation among medical residents during the COVID-19 pandemic in Tehran.MethodsThis study conducted a cross-sectional online survey among medical residents in various specialties in Tehran, Iran, amidst the COVID-19 pandemic. Suicidal ideation was assessed using the Beck Scale for Suicidal Ideation (BSSI), while depression, anxiety, and stress were measured using the DASS-21. It also collected demographic and clinical data from the participants. The data were analyzed using descriptive statistics, the Chi-square test, and multiple linear regression to examine the prevalence and determinants of suicidal ideation among medical residents.ResultsThe study enrolled 353 medical residents and found that 34.3% of them had suicidal ideation, with 10.2% indicating a high risk. The study also found high levels of depression, anxiety, and stress among the participants. The variables that significantly predicted suicidal ideation were depression, history of alcohol/substance use, personal history of suicide attempts, history of self-mutilation, family history of suicide attempts, number of shifts in a month, death of close persons because of COVID-19, and income. Depression was the strongest predictor of suicidal ideation.ConclusionThese findings underscore the urgent need for effective interventions and support systems to address the mental health needs of medical residents in Iran. The strategies should prioritize destigmatizing mental health, promoting access to mental health services, fostering a supportive training environment, and enhancing income opportunities
