RESUMO
Background: COVID-19 has turned into a global public health crisis. This study intended to compare demographic characteristics, disease severity, treatment methods, and clinical outcomes in hospitalized patients with COVID-19 during the third and fourth waves of the pandemic in Golestan Province, Iran. Methods: In this cross-sectional study, the clinical epidemiology of all COVID-19 patients, who were hospitalized in two educational hospitals in Golestan Province for 30 days from the start of the third and fourth waves of the coronavirus pandemic in 2021-2022, was assessed. Their electronic medical records were used to collect their epidemiological, demographic, laboratory, and clinical information and treatment outcome. Results: In all, 930 electronic medical records of the hospitalized patients (351 in the third wave and 579 in the fourth wave) were studied. In the third and fourth waves, 29.06% and 13.13% of the patients had severe COVID-19, respectively (P = 0.001). The number of deaths in the third wave was larger compared to the fourth wave (P = 0.015). The mean duration of hospitalization was longer in the third wave than in the fourth wave (P = 0.001). The drugs administered most in these two waves were remdesivir, dexamethasone, and heparin, and the patients who received these drugs were compared in the third and fourth waves (P = 0.001). Conclusion: The reduced rate of mortality in the fourth wave was compared to the third wave. This reduction can be attributed to the change in the national strategy adopted in terms of hospitalization criteria and treatment protocols taking into account the acquired experience, earlier hospitalization, and start of drug therapy.
RESUMO
OBJECTIVE: To determine the incidence of extra-pulmonary tuberculosis (EPTB) and examine the risk factors and the clinical features of the disease over a ten-year period. METHODS: Retrospective study of records of patients who were followed and registered in the TB registry programme in the health district of Gorgan, Iran from January 1, 2008, through December 31, 2017. RESULTS: Among 2280 TB records, 609 (26.71%) were EPTB. They were mostly female patients (53.7%) and residents in rural areas (56.5%) with a mean age of 40.55 years [±16]. The average age of female patients (37.55 years [±16.99]) was lower than of male patients (44.07 years [±20.59]). The median of the incidence rate was 7.5 per 100 000 inhabitants for EPTB; biopsy and pathology were the best methods for the detection of EPTB. The most frequent forms of EPTB were lymphatic TB (193/609 = 31.7%) and pleural TB (158/609 = 25.9%). In most cases (245/609 = 40.2%), one to three months elapsed between occurrence of symptoms and final confirmation of EPTB. The outcome of EPTB was weaker than of pulmonary TB (PTB). CONCLUSION: Our most important finding was the increasing incidence of EPTB, which shows the importance of attention to this disease. Lymph node and pleural tissue were the most commonly infected tissues. Skeletal TB presents a challenge in the diagnosis and treatment of EPTB.
OBJECTIF: Déterminer l'incidence de la tuberculose extra-pulmonaire (EPTB) et examiner les facteurs de risque et les caractéristiques cliniques de la maladie sur une période de dix ans. MÉTHODES: Etude rétrospective des dossiers des patients qui ont été suivis et enregistrés dans le programme d'enregistrement de la TB dans le district de santé de Gorgan, en Iran, du 1er janvier 2008 au 31 décembre 2017. RÉSULTATS: Parmi 2.280 enregistrements de TB, 609 (26,71%) étaient des EPTB. Il s'agissait principalement de femmes (53,7%) et de résidents des zones rurales (56,5%) avec un âge moyen de 40,55 ans [± 16]. L'âge moyen des patients de sexe féminin (37,55 ans [± 16,99]) était inférieur à celui des hommes (44,07 ans [± 20,59]). La médiane du taux d'incidence était de 7,5 pour 100.000 habitants pour l'EPTB; la biopsie et la pathologie étaient les meilleures méthodes pour la détection de l'EPTB. Les formes les plus fréquentes d'EPTB étaient la TB lymphatique (193/609 = 31,7%) et la TB pleurale (158/609 = 25,9%). Dans la plupart des cas (245/609 = 40,2%), un à trois mois s'étaient écoulés entre l'apparition des symptômes et la confirmation finale de l'EPTB. Le résultat de l'EPTB était plus faible que celui de la TB pulmonaire (PTB). CONCLUSION: Notre découverte la plus importante a été l'incidence croissante d'EPTB, ce qui montre l'importance de l'attention portée à cette maladie. Les ganglions lymphatiques et les tissus pleuraux étaient les tissus les plus fréquemment infectés. La TB osseuse présente un défi dans le diagnostic et le traitement de l'EPTB.

Background: It is essential to constantly review the risk factors and treatment outcomes of tuberculosis (TB). This study evaluated some important risk factors of TB over five years. Methods: Between 2013 and 2018, all available information and possible risk factors related to TB patients were analyzed from the TB registry program of the health district of Gorgan, Iran. Results: Among 349 TB patients, 194 (55.59%) were males and 167 (47.85%) had at least a comorbidity. The death rate was higher in the age group more than 65 years (p < 0.001), the low-educated group (P = 0.012), and patients with underlying diseases, especially diabetes (p < 0.001). In total, univariate and multivariate statistical analyzes showed that having comorbidity (OR = 4.34; 95% CI 1.49 - 13.49), as well as, being jobless (OR = 3.07; 95% CI 1.19 - 8.59) were the main factors influencing the adverse events. Conclusion: According to the study, aging, underlying diseases, and cultural poverty include a higher share of the main risk factors for active TB and/or treatment outcomes. By considering these risk factors and training the medical staff continually, we can reduce the time of TB diagnosis, and prevent it from spreading.
RESUMO
Background: Considering the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic, which causes coronavirus disease 2019 (COVID-19), we aimed to report the clinical features of 427 patients with COVID-19 and the outcomes after one-month admission to major teaching hospitals in the northeast of Iran. Materials and Methods: Data of patients hospitalized with COVID-19 from 20 February 2020 to 20 April 2020 was analyzed using the R software. The cases and their outcomes were monitored up to one month following their admission. Results: Among 427 patients with a median age of 53 years (50.8% male), 81 (19%) were directly admitted to the ICU ward, and 68 (16%) died during the study. The mean (SD) lengths of hospital stay were significantly higher in the non-survivors (6 (9) days) than survivors (4 (5) days) (P = 0.018). Ventilation need was reported in 67.6% of the non-survivors and 0.8% of the survivors (P < 0.001). Cough (72.8%), fever (69.3%), and dyspnea (64.0%) were the most common symptoms. There were more comorbidities in the severe cases (73.5%) and non-survivor (77.5%). Liver and kidney damage were significantly more common in non-survivors. Ninety percent of the patients had at least one abnormal chest CT scan finding, including crazy paving and consolidation patterns (27.1%), followed by the ground-glass opacity (24.7%). Conclusion: Results showed that the patients' age, underlying comorbidities, levels of SpO2, and laboratory findings at the time of admission may predict the progress of the disease and can be considered mortality-related factors.
RESUMO
BACKGROUND: This cross-sectional study was performed on isolates of Klebsiella pneumoniae, and E.coli from clinical specimens of patients admitted to Sayyad Shirazi Hospital by census sampling method in 2019. Antibiogram testing was performed using the disk diffusion method as defined by the Clinical and Laboratory Standards Organization for performing this test. Finally, the abundance of genes was evaluated by PCR using specific primers. Frequency, percentage, mean±SD were used to describe the data. Chi-square and Fisher's exact tests were used to compare the presence and absence of the studied genes alone and in the presence of each other. RESULT: This study was performed on 130 positive samples, isolated from 32 (24.6%) males and 98 (65.4%) females with a mean age of 43.78 ± 21.72. From the total number of 130 isolates, 84 (64.6%) consisted of E.coli, and 46 (35.4%) were Klebsiella. Most of the cultures were urine and vaginal (61.5%). The highest antibiotic resistance in isolates was cephalexin and cefazolin (67.9% in E.coli & 63% in Klebsiella). Colistin was identified as the most effective antibiotic (100%) in both. AMPC extendedspectrum ß-lactamase genes were present in 40 (30.8%) isolates. The highest frequency about the gene pattern of AMPC positive ß-lactamase bacteria was correlated to DHA, FOX, and CIT genes, while none of the samples contained the MOX ß-lactamase gene. E.coli and Klebsiella beta-lactamase-producing AMPC isolates were also significantly correlated with antibiotic resistance to the cephalosporin class (P <0.05). CONCLUSION: This study indicated a high percentage of resistance to third and fourth generation cephalosporins. Hence, careful antibiogram tests and prevention of antibiotic overuse in infections caused by AMPC-producing organisms and screening of clinical samples for the resistance mentioned above genes and providing effective strategies to help diagnose and apply appropriate treatments and change antibiotic usage strategies can partially prevent the transmission of this resistance.

OBJECTIVES: There is little information about Coronavirus Disease 2019 (COVID-19) management for critically ill patients. Most of these patients develop acute respiratory distress syndrome (ARDS) due to excessive inflammatory response and the ensuing cytokine storm. Anti-inflammatory drugs including corticosteroids can be used to effectively reduce the effect of this cytokine storm and lung damage. However, corticosteroids can have side effects, so simultaneous administration of immunoglobulin (IV-IG) and interferon-beta can help manage treatment using corticosteroids. Therefore, we designed a trial to test our hypothesis that early administration of dexamethasone in combination with IV-IG and interferon-beta can reduce the effect of the cytokine storm in critically ill patients COVID-19. TRIAL DESIGN: A phase two multi-center randomized controlled trial (RCT) with three parallel arms (1:1:1 ratio). PARTICIPANTS: They will be hospitalized patients with severe COVID-19 who have positive RT-PCR test and have blood oxygen saturation levels (SpO2) less than 90% and respiratory rate higher than 24 per minute or have involvement of more than 50% of their lung when viewed using computed tomography (CT)-scan. The age range of patients will be 18-70 years old. EXCLUSION CRITERIA: the need for intubation; allergy, intolerance, or contraindication to any study drug including dexamethasone, IV-IG, and interferon-beta; pregnancy or lactation; known HIV positive or active hepatitis B or C. The study will be conducted in several hospitals of the Golestan province, Iran. INTERVENTION AND COMPARATOR: The study subjects will be randomly allocated to three treatment arms: two experimental groups (two arms: Intervention 1 and Intervention 2) and one Control Group, which will be matched for age and sex using frequency matching method. Each eligible patient in the control arm will receive the standard treatment for COVID-19 based on WHO guidelines and the Ministry of the Health and Medical Education (MOHME) of Iran. Each patient in the Intervention Group 1 will receive the standard treatment for COVID-19 and dexamethasone, at the first 24 hours' time of admission. The intervention begins with the administration of dexamethasone based on the SpO2 levels. If the level of SpO2 does not improve after 24 hours, IV-IG (400 mg/kg once daily for 5 days) and interferon-beta (7 doses every other day) will be prescribed along with dexamethasone administration. In Intervention Group 2, the administration of dexamethasone will be started within the first 24 hours' time of admission and will be continued for 48-72 hours and then the SpO2 level will be checked. Then, if the level of SpO2 has not improved after that time, IV-IG and interferon-beta will be prescribed as the same dosage as Group 1. If the percentages of the SpO2 level are between 85 and 90/ 80 and 85/ 75 and 80/ less than 75, the dosages will be 4 mg every 12 hours/ 4 mg every 8 hours/ 8 mg every 12 hours/ 8 mg every 8 hours, respectively. According to the WHO recommendation, all participants will have the best available supportive care with full monitoring. MAIN OUTCOMES: Primary: An increase in the SpO2 level to reach more than 90% in each case, which will be assessed by the oximeter. Secondary: The duration of hospital stays; intubation status and the percentage of patients who are free of mechanical ventilation; the mortality rates during hospitalization and one month after the admission time. RANDOMISATION: Participants will be allocated into either control or intervention groups with a 1:1:1 allocation ratio using a computer random number generator to generate a table of random numbers for simple randomization. BLINDING (MASKING): The project's principal investigator (PI) is unblinded. However, the PI will not analyse the data and interpret the results. An unblinded researcher (a pharmacist) will cover the drug's bottles with aluminium foil and prepare them interventions and control drugs in a syringe with a code so that patients are blinded. This person will have no patients contact. The staff and nurses, caring for the patients, will be unblinded for each study group due to the nature of this study. The staff that take outcome measurements will be blinded. The laboratory technicians will also be blinded as well as the statistical team. These study statisticians will have access to coded data and will analyse the data labelled as group X, group Y, and group Z. NUMBERS TO BE RANDOMISED (SAMPLE SIZE): The target sample size will be 105 critically ill COVID-19 patients, who will be allocated randomly to the three trial arms with 35 patients in each group. TRIAL STATUS: Recruitment is ongoing. The study began on April 18 2020 and will be completed June 19 2020. This summary describes protocol version 1; April 2 2020.
