Abstract
BACKGROUND Cancer is a significant public health concern and the second leading cause of death. This study aims to visualize spatial patterns of top common cancer types and identify high-risk and low-risk counties for these cancers in Iran from 2014 to 2017. METHODS In this study, we analyzed 482,229 newly diagnosed cancer cases recorded by the Iranian National Population-Based Cancer Registry from 2014 to 2017. We employed a purely spatial scanning model and local Moran I analysis to explore spatial patterns across Iran. RESULTS Approximately 53% of all cases were male. The average age of cancer diagnosis was 62.58 ± 17.42 years for males and 56.11 ± 17.33years for females. Stomach cancer was the most common cancer in men. The northern and northwestern regions of Iran were identified as high-risk areas for stomach cancer in both genders, with a relative risk (RR) ranging from 1.26 to 2.64 in males and 1.19 to 3.32 in females. These areas recognized as high-risk areas for trachea, bronchus, and lung (TBL) cancer specifically in males (RR:1.15-2.02). Central regions of Iran were identified as high-risk areas for non-melanoma skin cancers in both genders, ranking as the second most common cancer (RR:1.18-5.93 in males and 1.24-5.38 in females). Furthermore, bladder cancer in males (RR:1.32-2.77) and thyroid cancer in females (RR:1.88-3.10) showed concentration in the central part of Iran. Breast cancer, being the most common cancer among women (RR:1.23-5.54), exhibited concentration in the northern regions of the country. Also, northern regions of Iran were identified as high-risk clusters for colon cancer (RR:1.31-3.31 in males and 1.33-4.13 in females), and prostate cancer in males (RR:1.22-2.31). Brain, nervous system cancer, ranked sixth among women (RR:1.26-5.25) in central areas. CONCLUSIONS The study's revelations on the spatial patterns of common cancer incidence in Iran provide crucial insights into the distribution and trends of these diseases. The identification of high-risk areas equips policymakers with valuable information to tailor targeted screening programs, facilitating early diagnosis and effective disease control strategies.

Abstract
The pandemic of severe acute respiratory syndrome coronavirus 2 raised the attention towards bacterial coinfection and its role in coronavirus disease 2019 (COVID-19) disease. This study aims to systematically review and identify the pooled prevalence of bacterial coinfection in the related articles. A comprehensive search was conducted in international databases, including MEDLINE, Scopus, Web of Science, and Embase, to identify the articles on the prevalence of bacterial coinfections in COIVD-19 patients from 1 December 2019 until 30 December 2020. All observational epidemiological studies that evaluated the prevalence of bacterial coinfections in patients with COVID-19 were included without any restriction. Forty-two studies including a total sample size of 54,695 were included in the analysis. The pooled estimate for the prevalence of bacterial coinfections was 20.97% (95% CI: 15.95-26.46), and the pooled prevalence of bacterial coinfections was 5.20% (95% CI: 2.39-8.91) for respiratory subtype and 4.79% (95% CI: 0.11-14.61) for the gastrointestinal subtype. The pooled prevalence for Eastern Mediterranean Regional Office and South-East Asia Regional Office was 100% (95% CI: 82.35-100.00) and 2.61% (95% CI: 1.74-3.62). This rate of coinfection poses a great danger towards patients, especially those in critical condition. Although there are multiple complications and adverse effects related to extensive use of antibiotics to treat patients with COVID-19, it seems there is no other option except applying them, and it needs to be done carefully.

Abstract
AbstractIn the present work, the influence of inclined baffles and an elastic vibrating beam is investigated on the flow pattern and heat transfer rate in a rectangular channel. The cylinder with the elastic vibrating beam develops the vibrating flow. The computations are based on the finite element method (FEM); Galerkin least-squares scheme and Newton–Raphson iterative method are implemented to solve the governing equations. The fluid structure-interaction (FSI) method is used to analyze the elastic vibrating beam. The friction factor coefficient and Nusselt number are examined for the inclined and conventional baffles. The flow regime is assumed to be laminar for various baffle angles and Reynolds numbers. The vibrating beam is connected to the cylinder located in the channel entrance. Optimized cases with the maximum heat transfer and minimum friction factor are introduced. The novelty of this study is the simultaneous use of the elastic vibrating beam and inclined baffles in a rectangular channel. The results show that mounting an elastic vibrating beam on the cylinder leads the heat transfer rate to increase. The channel with an elastic vibrating beam and inclined baffles at 135° is the optimized case compared to other cases.Article Highlights
Take advantage of using an elastic vibrating beam in a rectangular channel.
Influences of inclined baffles on thermal performance are examined numerically.
The optimum case for the channel with inclined-baffles is reported.

Abstract
Orf disease is caused by a double-stranded DNA virus of the Parapox family. Human infection is mostly due to occupational hazard and handling infected animals. Our patient was an 18-year-old woman who suffered burns in 2015. Total Burn Surface Area (TBSA) was 22% and cause of burn was flame. One week after hospital admission, she underwent skin grafts of her upper extremities. However, vegetative granulomatous ulcerations developed on the wound, resulting in the grafts failing to take. After careful investigation into the patient's history, we discovered that the water used to douse the flames was from a drinking trough for sheep. Suspecting Orf disease, we disinfected the wounds and dressing tools with Dakin's solution. We waited about 12 days to perform a new skin graft, and most of the grafted skin took. PCR test for Parapox virus was positive. Orf disease should be considered a distinct possibility in burn patients with a history of probable contamination. Manipulation of the disease in the early stages of burn wound could potentially spread it and change the degree of the wound, therefore being aware of this possibility can save the patient unnecessary pain and time. To prevent a nosocomial outbreak of Orf, wound care and wound disinfection should be scrupulously carried out. Isolation and disinfection of the entire dressing tool should be considered. Educating wound care providers in burn hospitals and scrupulous wound disinfection would protect the patient from cross contamination and allow skin grafts to take with ease, without the formation of ulcerations associated with Orf.

Abstract
BACKGROUND Apoptosis plays a key role in the pathogenesis of cardiac diseases. We examined the influence of the renin-angiotensin system (RAS) on different regulators of apoptosis using an isolated hemoperfused working porcine heart model of acute ischemia (2 h), followed by reperfusion (4 h). METHODS AND RESULTS 23 porcine hearts were randomized to 5 groups: hemoperfused non-infarcted hearts (C), infarcted hearts (MI: R. circumflexus), infarcted hearts treated with quinaprilat (Q), infarcted hearts treated with angiotensin-I (Ang I), and infarcted hearts treated with angiotensin-I and quinaprilat (QA). Fas, Bax, bcl-2 and p53 proteins were increased in MI hearts and further elevated by Ang I. Quinaprilat reduced Bax and p53. Bcl-2 was elevated in Q and reduced in QA. An early upregulation of caspase-3 gene and protein expression was detected in MI and Ang I hearts compared to C. Q reduced caspase-3 gene expression, but had no effect on caspase-3 and Fas protein. CONCLUSIONS These data suggest that the RAS plays a pivotal role in cardiac apoptosis which is the early and predominant form of death in myocardial infarction. Ischemia/reperfusion induces programmed cell death via extrinsic and intrinsic pathways. Early treatment with quinaprilat attenuated cardiomyocyte apoptosis.

Abstract
Endothelial cells play a crucial role in the pathogenesis of many diseases and are highly sensitive to low gravity conditions. Using a three-dimensional random positioning machine (clinostat) we investigated effects of simulated weightlessness on the human EA.hy926 cell line (4, 12, 24, 48 and 72 h) and addressed the impact of exposure to VEGF (10 ng/ml). Simulated microgravity resulted in an increase in extracellular matrix proteins (ECMP) and altered cytoskeletal components such as microtubules (alpha-tubulin) and intermediate filaments (cytokeratin). Within the initial 4 h, both simulated microgravity and VEGF, alone, enhanced the expression of ECMP (collagen type I, fibronectin, osteopontin, laminin) and flk-1 protein. Synergistic effects between microgravity and VEGF were not seen. After 12 h, microgravity further enhanced all proteins mentioned above. Moreover, clinorotated endothelial cells showed morphological and biochemical signs of apoptosis after 4 h, which were further increased after 72 h. VEGF significantly attenuated apoptosis as demonstrated by DAPI staining, TUNEL flow cytometry and electron microscopy. Caspase-3, Bax, Fas, and 85-kDa apoptosis-related cleavage fragments were clearly reduced by VEGF. After 72 h, most surviving endothelial cells had assembled to three-dimensional tubular structures. Simulated weightlessness induced apoptosis and increased the amount of ECMP. VEGF develops a cell-protective influence on endothelial cells exposed to simulated microgravity.
