Background: The ability to respond to any emergency before happening is a potential issue that manifests as operational readiness. This study aimed to evaluate the preparedness of prehospital emergency services of Mazandaran University of Medical Sciences in response to the epidemic of COVID-19. Materials and Methods: This cross-sectional study was performed in April 2020 using a translated standard checklist of the Pan American World Health Organization (PAHO). The list consists of four components of call management (6 items), first responders (operational codes with 3 items), medical transportation (including primary and interhospital with 16 items), and emergency medical services administration (including medical guidelines, human resources, and education with 11 items). Results: There were 168 operational logistics facilities and 555 personnel to cover organizational missions. Except for two items that scored half a point, the rest of the measures received total points (35 out of a maximum of 36 points with 97% of the total points). According to the complete scores, operational readiness was at a good level. Conclusion: The preparedness of the Center for Disaster Management and Medical Emergencies at Mazandaran University of Medical Sciences in the face of the COVID-19 epidemic has been at a good level. However, because of the continuation of the epidemic, strengthening the supply chain and empowering personnel are essential to sustainable readiness.

BACKGROUND: Gastric cancer is the fourth most common cause of worldwide cancer. Also in contrast to the huge advances in curing, the chance of living is very low even in surgery cases. Having a genetic predisposition plays an important role in cancer development. The association between Metallothionein-2A gene polymorphisms and the risk of adenocarcinoma has been widely studied, yet there is only one study on stomach diseases. OBJECTIVE: In this study, we aimed to investigate the association between 2 (MT-2A) polymorphisms and adenocarcinoma. METHODS: This cross-sectional case control study was performed between Mach 2014 and January 2015 at the Tuba Hospital of Sari, Iran. Peripheral blood samples were collected in EDTA tube. DNA extraction was performed using the spin column procedure. The MT-2A polymorphisms MT-2A (rs1610216), (rs28366003) were determined by polymerase chain reaction-restriction fragment length polymorphism analysis in 95 a topic adenocarcinoma patients and 90 healthy individuals from Iranian population. RESULTS: The MT-2A rs1610216 polymorphism increased the risk of adeno carcinoma in our Iranian population [OR: 3.8533; 95%CI, 1.3155-11.2869; P=0.0139] and rs28366003 [OR: 4.0978; 95%CI, 1.2521-13.4108; P=0.0197]. CONCLUSION: The MT-2A gene polymorphism was associated with the risk of adenocarcinoma in the Iranian population. RESUMO CONTEXTO: O câncer gástrico é a quarta causa mais comum de câncer em todo o mundo. Também em contraste com os enormes avanços na cura, a chance de viver é muito baixa, mesmo em casos de cirurgia. Ter uma predisposição genética desempenha um papel importante no desenvolvimento do câncer. A associação entre polimorfismos do gene metalotioneína-2A e o risco de adenocarcinoma tem sido amplamente estudada, mas há apenas um estudo sobre doenças estomacais. OBJETIVO: Neste estudo, objetivou-se investigar a associação entre 2 (MT-2A) polimorfismos e adenocarcinoma. MÉTODOS: Um estudo de controle de caso transversal foi realizado entre março de 2014 e janeiro de 2015 no hospital Tuba, Sari, Irã. Amostras de sangue periférico foram coletadas em tubo EDTA. A extração do ADN foi executada usando o procedimento da coluna da rotação. Os polimorfismos MT-2a MT-2A (rs1610216), (rs28366003) foram determinados pela análise do polimorfismo do comprimento do fragmento da reação-limitação de cadeia da polimerase em 95 pacientes com adenocarcinoma tópico e em 90 indivíduos saudáveis da população iraniana. RESULTADOS: O polimorfismo MT-2A rs1610216 aumentou o risco de adenocarcinoma de em nossa população iraniana. [OR: 3,8533; 95%CI, 1,3155-11,2869; P=0,0139] e rs28366003 [OR: 4,0978; 95%CI, 1,2521-13,4108; P=0,0197]. CONCLUSÃO: O polimorfismo do gene MT-2A foi associado ao risco de adenocarcinoma na população iraniana.

BACKGROUND: Gastric adenocarcinoma is the fourth most common cause of cancer-associated death worldwide. OBJECTIVE: We evaluated the immunological status of patients with gastric cancer before surgery and circulating cytokines as potential diagnostic biomarkers for gastric cancer. METHODS: We included 90 healthy controls and 95 patients with distal Gastric adenocarcinoma in Mazandaran, Sari, Iran. We measured serum IL-2, IL-10 and IL-12 Levels by a sandwich enzyme-linked immunosorbent assay using the IBL international GMBH kit. RESULTS: The serum IL-10 levels in the patients with Gastric adenocarcinoma were significantly higher than those of the healthy controls (P=0.02). There were no significant differences in serum IL-2 and IL-12 levels between patients with gastric cancer and healthy controls. CONCLUSION: Increased levels of IL-10 might be useful as diagnostic biomarkers for Gastric adenocarcinoma; however, this needs to be confirmed with larger number of patients and with control groups other than blood donors, properly age paired. These results suggest that positive expression of IL-10 may be useful as a molecular marker to distinguish stage of gastric cancers which can be more readily controlled. RESUMO CONTEXTO: O adenocarcinoma gástrico é a quarta causa mais comum de morte relacionada ao câncer em todo o mundo. OBJETIVO: Avaliar o status imunológico dos pacientes com câncer gástrico antes da cirurgia e as citocinas circulantes como potenciais biomarcadores diagnósticos para câncer gástrico. MÉTODOS: Incluímos 90 indivíduos controles saudáveis e 95 pacientes com adenocarcinoma gástrico distal em Mazandaran, Sari, Iran. Os níveis de soro Il-2, IL-10 e Il-12 foram medidos por um ensaio de imunoabsorção enzimática pela técnica de sanduíche usando o kit IBL International GmbH. RESULTADOS: Os níveis séricos IL-10 nos pacientes com adenocarcinoma gástrico foram significativamente superiores aos dos controles saudáveis (P=0,2). Não houve diferenças significativas nos níveis de soro IL-2 e IL-12 entre pacientes com câncer gástrico e controles saudáveis. CONCLUSÃO: Níveis aumentados de IL-10 podem ser úteis como biomarcadores diagnósticos para adenocarcinoma gástrico; no entanto, isso precisa ser confirmado com maior número de pacientes e com grupos de controle que não sejam doadores de sangue, adequadamente emparelhado por idade. Estes resultados sugerem que a expressão positiva do IL-10 pode ser útil como um marcador molecular para distinguir a fase de câncer gástrico que pode ser mais facilmente controlada.
