Diabetes mellitus (DM) is a disorder in which the body does not produce enough or respond to insulin normally, resulting in an abnormal increase in blood glucose levels. 90% of diabetes cases in pregnant women are gestational diabetes mellitus (GDM). It is known that fluctuations in the level of glucose and its irregularity led to disturbances in the health of both mother and fetus.The therapeutic strategies and options for the treatment of gestational diabetes are highlighted in this review. We havereviewed medicinal plants used in the treatment of gestational diabetes. Literature review indicates that medicinal plants are effective in treating osteoarthritis and have been clinically and scientifically proven. Natural medicines have been the subject of chemical studies and many plants are the subject of clinical trials. Their results are remarkable and significant. However, scientific exploration for bioactive constituents is becoming increasingly important and their mechanisms of actions to treat GDM are still ongoing.

Background: As the world witnessed the outbreak of coronavirus illness 2019 (COVID-19), a disorder developed as a result of a novel coronavirus, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), increasing genetics with healthcare evidence suggest a corresponding leadership to SARS as well as the Middle East Respiratory Syndrome (MERS). Aim: The aim of this review is to highlight Immune response of human body toward COVID-19. Materials and methods: This was a narrative review. A comprehensive literature search was done using PubMed, Google Scholar, Scopus, and EMBASE using the keywords, Immune Response; COVID-19; Vaccination; SARS-Cov-2; ACE2; Coronavirus; MERS. Results: A flow of viral components passes to the body by means of nostrils, mouth and eyes. SARS-CoV-2 is in a position to continue to become unnoticed extended than numerous influenza or coronaviruses. Its proteins can accomplish entry by unlocking the Angiotensin-Converting Enzyme 2 (ACE2) protein in the lung cells; viruses also possess antigens furthermore recognize that these are what cries the immunity into movement via making antibodies. Investigators demonstrate an extensive variety of immune cells respond to COVID-19 along with valuable source retrieval, discovering that might want to notify the manufacturing of a viable vaccination. Conclusion: The body's natural response to a viral infection is a non-invasive intrinsic response in which macrophages, neutrophils, and dendritic cells limit the virus's progression and may even prevent it by multiplying symptoms. This non-invasive solution is accompanied by an elastic response in which the body produces radicals that primarily adjust to the herpes virus.

Since December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged and spread quickly worldwide. The disease is generally mild in adult people but in any with comorbidities may proceed to acute respiratory distress syndrome (ARDS), pneumonia, and multi-organ dysfunction. By performing molecular tests on respiratory secretions can diagnose the virus. Elevated C-reactive protein (CRP) and normal/low white cell counts are common laboratory diagnoses of COVID-19 while the tomographic chest scan is usually irregular for many infected people. Some patients progress to respiratory failure, pneumonia, and finally death by the end of the first week of illness because of the sharp rise in inflammatory cytokines such as IL7, IL2, GCSF, IL10, MIP1A, MCP1, IP10, and TNFα. Various approaches to the COVID- 19 are being performed by scientists. Use of chemical medical drugs that are effective for other viral infections. Among them, remdesivir was approved by FDA on 1th May 2020 because of its impact to treat patients. Also, several studies have revealed that many Chinese herbal remedies have a remarkable impact on the healing process when simultaneously were used along with pharmacological drugs. In the meantime, many efforts have been made to produce an effective vaccine, and so far, the Ad5-vectored COVID-19 vaccine has been successful and has entered phase 2 in the human trial. The current review focus on epidemiology, virology, clinical features, diagnosis, and available treatment of coronavirus that might assist researchers and clinicians in establishing action options for timely against this infection.

Objective Helicobacter pylori is one of the most common causes of gastric infections in humans. It is estimated that approximately 50% of people around the world are infected with this bacterium. This study aimed to determine the antibiotic resistance pattern, as well as the frequency of cagA and vacA genes in H. pylori isolates obtained from patients in the clinical centers in Tabriz city, Iran. Results The culture method detected 100 (45.25%) H. pylori isolates from 221 biopsy samples during 3 years. The results showed that 63% and 81% of the isolates were positive for cagA and vacA genes, respectively. The highest resistance of isolates was seen against metronidazole (79%) and amoxicillin (36%), respectively. Also, the isolates showed the least resistance to tetracycline (8%).

Beta-lactamases are the most common cause of bacterial resistance to beta-lactam antibiotics. AmpC-type beta-lactamases hydrolyze cephalosporins, penicillins, and cephamycins. Therefore, the study aims was to determine antibiotic resistance and to investigate the presence of AmpC beta-lactamase gene in clinical strains of Escherichia coli isolated from hospitalized patients in Tabriz. In this cross-sectional descriptive study, 289 E. coli specimens were collected from clinical specimens. Disk diffusion method and combined disk method were used to determine the phenotype of extended spectrum β-Lactamase producing (ESBLs) strains. Then PCR was used to evaluate the presence of AmpC (FOX) beta-lactamase gene in the strains confirmed in phenotypic tests. Antibiotic resistance was also determined using disk diffusion by the Kibry-Bauer method. A total of 121 isolates were identified as generators of beta-lactamase genes. 72 (59.5 %) isolates producing ESBL and 49 (40.5 %) isolates were identified as AmpC generators. In the PCR test, 31 isolates contained the FOX gene. The highest resistance was related to the antibiotics amoxicillin (76.12%), ceftazidime (70.24%) and nalidixic acid (65.05%). The results indicate an increase in the prevalence of beta-lactamase genes and increased resistance to beta-lactam antibiotics, which can be the result of improper use of antibiotics and not using antibiotic susceptibility tests before starting treatment. Also, using phenotypic and molecular diagnostic methods such as PCR together can be very useful.

Since the outbreak of the Corona pandemic in December 2019, many people affected, especially medical care laborers, who deal with the treated cases. Coronavirus disease 2019 not only affects the body parts, but also extends to the psychological symptoms. The purpose of this research is to explore the impact of the pandemic on the mental prosperity of the laborers. Clinical staff members from the administration emergency clinic, Lahore, were enlisted. A poll was used to collect data on the segment information, a sleeping disorder, despondency and stress manifestations. Correlation of the segment information and the mental factors were done among the sleeping and non-sleeping disorder samples. All 356 medical service laborers were selected for this investigation. There were manifestations of misery in 222 (62.35%), nervousness in 227 (64.76%), stress in 197 (55.33%) and sleep deprivation in 190 (53.37%) of members. Gentle to extreme side effects of melancholy (91.65% vs 28.9%), nervousness (83.1% vs 41.6%) and stress (84.26% vs 22.22%) were seen predominately in the sleep deprivation gathering (P.001). Insomnia was more pronounced in the members with low training levels (78.08%) versus post-advanced education (30.9%). Paramedics, attendants, and medical service laborers in confinement/serious consideration units were more inclined to the sleep deprivation (P.001). Mental prosperity of medical care laborers was influenced because of Coronavirus pandemic. Attendants, paramedics, and those working in the detachment unit showed a critical sleeping disorder. The results and indicators have proven that there is a relationship between the infection with the Corona pandemic and occurrence of disorders in psychological behavior. Therefore, the psychological rehabilitation sessions must be conducted for those infected and those in contact with the Corona cases to relieve the burden of that patients to raise their psychological conditions and support the immune system such that resist against the infection.

People with beta-thalassemia major are more likely to acquire blood-borne viral infections due to the need for frequent blood transfusions. Of these viruses, hepatitis B virus (HBV) and hepatitis C virus (HCV) are of particular importance. In this study, the prevalence of HBV, HCV and their risk factors in beta-thalassemia major patients in East Azerbaijan province was investigated. The study was descriptive cross-sectional, and 116 beta-thalassemia major patients who received blood in Shahid Ghazi hospital and Children’s hospital in Tabriz city were studied. Data were collected by a questionnaire, and blood samples of patients in terms of serum markers HCV-Ab, HBsAg and HBs-Ab were analyzed by ELISA, and positive HCV-Ab results were confirmed by Real Time-PCR. Then using SPSS software version 22 and with the help of t-tests including Anova T-test, Man-Whitney U test, Independent sample t-test, chi-square and Fisher exact test, Statistical studies were performed. Of the 116 patients studied, no HBsAg positive cases were found. Four patients (3.4%) were positive for HCV-Ab, of which two patients (1.7%) became HCV-RNA positive after Real Time-PCR. There was a significant relationship between HCV-Ab positive and HCV-RNA positive (P = 0.000), blood transfusion intervals (P = 0.043), number of injected blood units (P = 0.001) and duration of blood transfusion (P = 0.006). The prevalence of HCV was lower in patients who started receiving blood after a blood donor screening program. HCV is less prevalent in thalassemia patients in East Azerbaijan province than in some studies in the country and various global statistics. After 1996, the prevalence of HCV in the thalassemia patient population has decreased significantly, and it seems that HCV infections since 1996 have been associated with various factors such as people’s jobs, position, behaviour in society, etc.
