World is still struggling with widespread dissemination and many unanswered questions about Coronavirus disease-19(COVID-19). Global efforts introduced several candidate vaccines against causing COVID-19, mostly requires require 2 doses of injections and some with about 90-95% efficacy. All strategies against the spread of infection are placed on breaking the chain of virus transmission though protective public health measures and mass vaccination, as yet. The current situation emphasis on the global need for carefully designed policies to maximize vaccine access and uptake. The risk compensation theory states that a drop in perceived risk caused by access to prevention measures may lead to an increase in risky behaviors. The current pandemic has faced people to the sense of risk compensation and behavior change in response to a perceived risk level. Risk compensation phenomenon may significantly defeat the benefits of COVID-19 vaccination, especially if the vaccine is not very effective in real life or in high-risk populations. Acknowledging and be conscious of Peltzman risk compensation has crucial importance in counteracting and neutralizing the false complacency of community also lend more weight to public health efforts. The public health messages and practices should be clearly expressed, straightforward, reliable and applicable. It is important that as efforts made to encourage mass vaccination of population other NPIs needs to be re-established and implemented to ensuring strike the balance of learning to live with COVID-19 in parallel with daily activities and job tasks.
Acute bronchiolitis is one of the most common lower respiratory tract infections in children with less than 2 years of age. Nowadays, molecular methods provide an opportunity to better understand the etiology of bronchiolitis. Several viral agents including Respiratory syncytial virus (RSV), Rhinovirus, Parainfluenza and Human bocavirus (HBoV) are responsible for acute bronchiolitis. There are growing studies on the prevalence of HBoV in patients with bronchiolitis. The present systematic review and meta-analysis were conducted to determine the pooled prevalence of HBoV in the respiratory samples of children with acute bronchiolitis. A literature search was conducted in the databases of PubMed, Scopus and Web of Science to recruit studies reporting the frequency of HBoV in <2-year-old children with acute bronchiolitis from 2005 to 2019. Only studies that used polymerase chain reaction (PCR)-based methods to detect the virus in nasopharyngeal samples were included. A total of 22 studies assessing 6751 cases were analyzed. According to the meta-analysis based on the random-effects model, the overall prevalence of HBoV in children with <2 years old was obtained 13% (95% CI: 0.09-0.17). Additionally, the rates of single (as the sole organism) and mixed (in combination with other viruses) HBoV infections were 4% and 9%, respectively. This study showed a high rate of HBoV detection in children with acute bronchiolitis. This should be considered as part of a diagnostic test panel for respiratory infections in children with bronchiolitis.
This study was aimed to investigate the relationship between spiritual health and physical activity among Iranian pregnant women during 2015. A cross-sectional descriptive-analytic design was adopted. A total number of 411 participants were selected by convenience sampling from Iranian women who regularly attended health centers for prenatal care. Data were collected using demographic questionnaire and Health-Promoting Lifestyle Profile questionnaire, 2nd edition. (Spiritual health and physical activity are two components of health-promoting lifestyle.) The data were analyzed, using descriptive statistics, t test, one-way ANOVA, Pearson's correlation coefficient, and regression. p values <0.05 were considered significant. The mean age of pregnant women was 27.90 ± 6.03 years. Spiritual health had the highest score (25.86 ± 4.7) and physical activity had the lowest score (11.31 ± 3.27), among six Health-Promoting Lifestyle Profile subscales. In fact, there was a statistically significant correlation between spiritual health and physical activity (p = 0.000). According to results, pregnant women have higher spiritual health and lower physical activity scores. There was a statistically significant correlation between spiritual health and physical activity. The findings of this study can be used in prenatal care, midwifery education, and maternal health policies.
Background and Aims Vaccine response is a concern in hemodialysis patients. Given that hemodialysis patients were not included in clinical trials, we aimed to synthesize the available evidence on the immunogenicity of coronavirus disease 2019 (COVID‐19) mRNA vaccines in hemodialysis patients. Methods We searched Scopus, PubMed, Sciencedirect, and finally google scholar databases for studies on COVID‐19 mRNA‐vaccines immunogenicity in hemodialysis patients up to December 1, 2021. Eligible articles measured antibodies against severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) spike or Receptor‐Binding Domain Antibody (S/RBD) postimmunization with COVID‐19 mRNA vaccines. The immunogenicity of the vaccine was evaluated using seroconversion rates measured between 21 and 30 days after the first immunization and between 14 and 36 days post the second dose. We included studies including participants without a history of COVID‐19 before vaccination. Healthy controls or health‐care workers served as the control groups. After selecting eligible articles, the data were finally extracted from included articles. We used a random effects model to estimate the pooled seroconversion rate after COVID‐19 mRNA vaccine administration. We assessed the heterogeneity between studies with the I 2 statistical index. Result We selected 39 eligible citations comprising 806 cases and 336 controls for the first dose and 6314 cases and 927 controls for the second dose for statistical analysis. After the first dose of mRNA vaccines, the seroconversion rate was 36% (95% confidence interval [CI]: 0.24–0.47) and 68% (95% CI: 0.45–0.91) in hemodialysis patients and the control group, respectively. While seroconversion rate after the second dose of mRNA vaccines was 86% (95% CI: 0.81–0.91) and 100% (95% CI: 1.00–1.00) in hemodialysis patients and the control group, respectively. Conclusion Although the immune response of hemodialysis patients to the second dose of the SARS‐CoV‐2 mRNA vaccine is very promising, the seroconversion rate of dialysis patients is lower than healthy controls. Periodically assessment of antibody levels of hemodialysis patients at short intervals is recommended.
Objective: Multiple myeloma (MM) remains an incurable disease that needs better recognition and further research. Previous studies elucidated the interaction between myeloma cells and showed the necessity of bone marrow stromal cells for the initiation and progression of MM. Many chemokines and their receptors including interleukin-8 (IL-8) and soluble interleukin-6 receptor (sIL-6R) play important roles in this interaction. The main purpose of this study is evaluating the serum level of IL-8 and sIL-6R on stage-I of MM patients and healthy controls. Methods: Serum samples from 30 stage-I MM patients (13 males and 17 females) and 30 healthy subjects as controls (13 males and 17 females) were examined in this study. The protein concentrations of serum IL-8 and sIL-6R were assessed by enzyme-linked immunosorbent assay (ELISA). Results: The mean level of IL-8 and sIL-6R were significantly elevated in stage-I MM. The mean levels of IL-8 were 1246.57±279.22 ng/ml in stage-I MM and 902.53± 294.61 ng/ml in controls (P<0.001). The mean levels of sIL-6R were 5.39±1.38 ng/ml and 4.1±1.14 ng/ml in stage-I MM and controls, respectively (P<0.001). The mean levels of IL-8 were 1342.18±193.4 ng/ml in patient females and 859± 278.2ng/ ml in control females (P <0.001). The mean levels of sIL-6R were 5.21±1.55 ng/ml and 3.91±1.22 ng/ml in patient females and control females, respectively (P=0.01). The mean level of sIL-6R in patient males and control males were 5.63±1.43 ng/ml and 4.34±1.04 ng/ml, respectively (P=0.01). A significant correlation (Pearson's correlation = 0.45, P=0.008) was observed in the population of females (patients and controls). Conclusion: The results of study suggest the possible involvement of IL-8 and the sIL-6R at stage-I MM and can better characterize the role of chemokines and their receptors in the disease process, especially in the early stages.
Reports show that other ordinary childhood infections like measles or Influenza are likely to reemerge. The re-emergence of infectious diseases may happen due to the direct impact of the pandemic on the community because of decreased access to health and medical services, interrupted transport systems, weaknesses in the supply chain, flight restrictions, closings of the border, and international trade problems. The most prevalent cause [60.9%] for low vaccine uptake and coverage during the current pandemic was fear of exposure to the COVID-19 virus outside the home. The expectation and hope that the pattern of reduction in transmission and number of influenza cases will continue over the next flu season depend on continued adherence to nonpharmaceutical interventions and their long-term application. But there is always the fear and threat of increasing the spread of Influenza by reducing the movement restrictions and low adherence to protective health measures due to vaccination. So far, not much information has been published about the interaction between different infectious diseases in the background of the coronavirus pandemic and related interventions. The purpose of this article is to examine the general effects of the Covid-19 vaccination on the spread of Influenza in the coming seasons.
