RESUMO

BACKGROUND: The aim of the present study was to compare the epidemiological patterns of severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infections, hospitalizations, deaths, and duration of hospitalization during the fourth, fifth and sixth epidemic waves of coronavirus disease 2019 (COVID-19) in Iran. METHODS: A multicenter retrospective observational study was conducted on hospitalized patients in four hospitals in the Babol district of northern Iran. The study periods were during the fourth, fifth, and sixth waves of the epidemic in Iran, (March 2021 to March 2022). A total of 13,312 patients with suspected COVID-19 were included. Patient demographics, medical history, length of hospital stay, and clinical outcomes were obtained from the hospital information system. Data on the cycle threshold (Ct) and SARS-CoV2 variant were collected for SARS-CoV2-positive cases. RESULTS: The highest number of hospitalized patients was reported during the fifth (Delta) wave (5231; 39.3%), while the lowest number of hospitalized patients was reported during the sixth (Omicron) wave (2143; 16.1%). In total, 6459 (48.5%) out of 13,312 hospitalized patients with suspected COVID-19 had a positive rRT-PCR result. The fifth (Delta) wave had the highest number of SARS-CoV2 rRT-PCR-positive hospitalized patients (3573, 55.3%), while the sixth (Omicron) wave had the lowest number (835, 12.9%). Moreover, 238 (3.7%) patients with laboratory-confirmed COVID-19 died. The hospital mortality rate was 6.8% in the fourth (Alpha) wave, which reduced to 2.7 and 3.5% in the fifth (Delta) and sixth (Omicron) waves, respectively (p < 0.001). CONCLUSIONS: This is the most comprehensive study evaluating the epidemiologic characteristics of laboratory-confirmed SARS-CoV2 cases in Iran during the Alpha, Delta, and Omicron waves. The highest number of SARS-CoV2-positive hospitalized patients was in the fifth wave of COVID-19 (dominance of the Delta variant), while the sixth wave (dominance of the Omicron variant) had the lowest number. Comorbidities were similar, and cardiovascular disease, diabetes, kidney disease, and hypertension were the main risk factors in all waves.

RESUMO

Placental mesenchymal dysplasia (PMD) is an uncommon placental lesion, which may mimic molar pregnancy at gross and microscopic examination. PMD can be associated with fetal growth restriction, Beckwith-Wiedemann syndrome, intrauterine fetal death, and preterm delivery. Nonetheless, it may also be associated with a normal appearing fetus. We aimed to emphasize that clinicians, radiologists, and pathologists should be aware of PMD as one of the etiologies of intrauterine growth restriction (IUGR). We presented the case of a 27-year-old gravida 1, para 1 woman who was admitted to Ayatollah Rouhani hospital, in Babol, Iran, at 30 weeks of gestation due to severe IUGR and fetal tachycardia. Ultrasound examination showed uteroplacental insufficiency and increased resistive index (RI) of umbilical artery. At last, a normal female fetus (1320 g) with no definitive anomalies was delivered by cesarean section. Pathological examination revealed cystically dilated stem villi with peripherally located thick-walled muscular stem vessels, and also stromal fibroblasts overgrowth in some stem villi. None of the examined sections revealed trophoblastic proliferation or stromal trophoblastic inclusion. The findings confirmed the diagnosis of PMD. Careful radiological and pathological examination should be performed in the case of IUGR for ruling out the rare placental abnormalities, including PMD.

RESUMO

Introduction. Coronavirus disease 2019 (COVID-19) identified in December 2019 in Wuhan, China, is associated with high mortality rates worldwide.Hypothesis/Gap Statement. Thrombotic problems, such as coagulopathy, are common in COVID-19 patients. Despite anticoagulation, thrombosis is more common in patients in the intensive care unit and patients with more severe disease. Although the exact mechanisms of coagulopathy in COVID-19 patients are still unclear, studies showed that overactivation of the renin-angiotensin system (RAS), cytokine storm, endothelial damage, formation of neutrophil extracellular traps (NETs), and also extracellular vesicles (EVs) in response to COVID-19 induced inflammation can lead to systemic coagulation and thrombosis.Aim. The management of COVID-19 patients requires the use of basic and readily available laboratory markers, both on admission and during hospitalization. Because it is critical to understand the pathophysiology of COVID-19 induced coagulopathy and treatment strategies, in this review we attempt to explain the underlying mechanism of COVID-19 coagulopathy, its diagnosis, and the associated successful treatment strategies.Conclusion. The exact mechanisms behind COVID-19-related coagulopathy are still unclear, but several studies revealed some mechanisms. More research is needed to determine the best anticoagulant regimen and to study other therapeutic options.

RESUMO

INTRODUCTION: Current histomorphological criteria in distinguishing two subtypes of hydatidiform moles has considerable inter-observer variability and limitations. In this regard, ancillary studies can aid pathologist to obtain an accurate diagnosis. Herein, we evaluated the utility of Glycophorin-A (GLA) in differentiating complete and partial moles. MATERIALS AND METHODS: In this case-control study, formalin-fixed paraffin-embedded blocks of 47 patients with pathologic diagnosis of complete and 42 partial hydatidiform moles were included and the diagnoses were confirmed by immunohistochemistry (IHC) for P57. Sections from all samples were stained for GLA using IHC method. Using 2 × 2 tables, the sensitivity, specifity, Positive and Negative Predictive Values (PPV and NPV) as well as accuracy of GLA were determined. RESULTS: Primary pathologic diagnosis was changed in 7.1% and types of hydatidiform mole were specified in 11.9% of the cases after review of the slides and IHC study for P57. NRBCs were found in 52.7% of the PM cases and none of CMs by pathologist in H&E sections. IHC study for GLA revealed positive result in one case of complete moles (2%) and 31 case of partial mole samples (73.8%). It was negative in 98% of the complete mole and 11 (26.2%) of partial mole cases. DISCUSSION: The results of this study showed a significant association between GLA immunoreactivity and type of molar pregnancy. Diagnostic sensitivity, specificity and accuracy of this marker for discrimination of molar pregnancy were 73.8%, 98% and 86.5%, respectively. Therefore, this marker can be utilized in differentiating partial and complete hydatidiform mole.

RESUMO

OBJECTIVE: Suicide is a social health problem worldwide. Anemia has been associated with depression. Since it remains debated whether anemia is associated with suicide independently of depression, we evaluate this probable association in women who attempted suicide through acute poisoning. METHODS: The study design was cross-sectional and performed on women who attempted suicide through intentional poisoning with age more than 18 years old. Different variables were evaluated and compared in patients with respect to anemia, depression, other psychiatric diseases and history of suicide. Independent t-tests and binary logistic regression were used for statistical analysis. FINDINGS: Nearly 26.2% of the women had anemia (n = 55). Most women with anemia were in the age group of 20-40 years (68.8%). 52.2% of the women were married. Mixed-drug poisoning was the most common (60.1%) followed by pesticide (8.9%), and antipsychiatric medications (8.4%). There was a significant difference in duration of hospitalization between anemic and nonanemic patients. Nearly 72.7% of the patients survived without complications. Anemia and depression were not significant predictive factors for depression and suicide. However, in our patients, the presence of other underlaying psychiatric disorders was a risk factor for suicidal attempt through acute poisoning. CONCLUSION: In women who attempted suicide through acute poisoning, anemia and depression were not predicting factors for suicide. However, the presence of other underlying psychiatric psychiatric disorders had a predictive value for the outcome of treatment. Length of hospital stay was also correlated with anemia.
