Although not common, gastrointestinal and liver symptoms have reportedly been the initial presentation of coronavirus disease‐2019 (COVID‐19) in a large group of patients. Therefore, knowing the frequency and characteristics of these manifestations of COVID‐19 is important for both clinicians and health policy makers. A systematic review and meta‐analysis of the available data on the gastrointestinal and liver manifestations of patients with COVID‐19 was performed. PubMed and Scopus databases and Google Scholar search engine were searched for published and unpublished preprint articles up to 10 April 2020. Original studies providing information on clinical digestive symptoms or biomarkers of liver function in patients with polymerase chain reaction confirmed diagnosis of COVID‐19 were included. After quality appraisal, data were extracted. Prevalence data from individual studies were pooled using a random‐effects model. Overall, 67 studies were included in this systematic review and meta‐analysis, comprising a pooled population of 13 251 patients with confirmed COVID‐19. The most common gastrointestinal symptoms were anorexia (10.2%, 95% confidence interval [CI] = 6.2%‐16.4%), diarrhea (8.4%, 95% CI = 6.2%‐11.2%), and nausea (5.7%, 95% CI = 3.7%‐8.6%), respectively. Decreased albumin levels (39.8%, 95% CI = 15.3%‐70.8%), increased aspartate aminotransferase (22.8%, 95% CI = 18.1%‐28.4%), and alanine aminotransferase (20.6%, 95% CI = 16.7%‐25.1%) were common hepatic findings. After adjusting for preexisting gastrointestinal (5.9%) and liver diseases (4.2%), the most common gastrointestinal findings were diarrhea (8.7%, 95% CI = 5.4%‐13.9%), anorexia (8.0%, 95% CI = 3.0%‐19.8%), and nausea (5.1%, 95% CI = 2.2%‐14.3%). Gastrointestinal and liver manifestations are not rare in patients with COVID‐19, but their prevalence might be affected by preexisting diseases. Diarrhea and mild liver abnormalities seem to be relatively common in COVID‐19, regardless of comorbidities
Background We aimed to determine the characteristics, risk factors, and outcomes associated with readmission in COVID-19 patients. Methods PubMed, Embase, Web of Science, and Scopus databases were searched to retrieve articles on readmitted COVID-19 patients, available up to September 25, 2021. All studies comparing characteristics of readmitted and non-readmitted COVID-19 patients were included. We also included articles reporting the reasons for readmission in COVID-19 patients. Data were pooled and meta-analyzed using random or fixed-effect models, as appropriate. Subgroup analyses were conducted based on the place and duration of readmission. Results Our meta-analysis included 4823 readmitted and 63,413 non-readmitted COVID-19 patients. The re-hospitalization rate was calculated at 9.3% with 95% Confidence Interval (CI) [5.5%–15.4%], mostly associated with respiratory or cardiac complications (48% and 14%, respectively). Comorbidities including cerebrovascular disease (Odds Ratio (OR) = 1.812; 95% CI [1.547–2.121]), cardiovascular (2.173 [1.545–3.057]), hypertension (1.608 [1.319–1.960]), ischemic heart disease (1.998 [1.495–2.670]), heart failure (2.556 [1.980–3.300]), diabetes (1.588 [1.443–1.747]), cancer (1.817 [1.526–2.162]), kidney disease (2.083 [1.498–2.897]), chronic pulmonary disease (1.601 [1.438–1.783]), as well as older age (1.525 [1.175–1.978]), male sex (1.155 [1.041–1.282]), and white race (1.263 [1.044–1.528]) were significantly associated with higher readmission rates ( P < 0.05 for all instances). The mortality rate was significantly lower in readmitted patients (OR = 0.530 [0.329–0.855], P = 0.009). Conclusions Male sex, white race, comorbidities, and older age were associated with a higher risk of readmission among previously admitted COVID-19 patients. These factors can help clinicians and policy-makers predict, and conceivably reduce the risk of readmission in COVID-19 patients.
Objective: The aim of this study is to evaluate the preventive effects of carvedilol on doxorubicin-induced cardiotoxicity. Methods: In this trial, 70 female patients with breast cancer who were candidates to receive doxorubicin were enrolled, from which 30 were selected randomly to receive carvedilol 6.25 mg daily during chemotherapy, with the rest receiving placebo as the control group. Both groups were evaluated 1 week before and 1 week after chemotherapy by measuring the left ventricular ejection fraction and strain/strain rate. Results: Data analysis showed that the case group presented no significant reduction in strain and strain-rate parameters after intervention, while there was a significant reduction in these parameters in the control group (all p values <0.001). Also, the mean differences of strain parameters in the case group were significantly less than in the control group in all evaluated heart walls (basal septal strain, p = 0.005, basal lateral strain, p = 0.001, basal inferior strain, p < 0.001, and basal anterior strain, p < 0.001); the same was true for the strain-rate parameters (the p values for basal septal, basal lateral, basal inferior and basal anterior strain rate were 0.037, 0.037, 0.002 and <0.001, respectively). Conclusion: This study shows that carvedilol can prevent doxorubicin-induced cardiotoxicity. Whether this prophylaxis should be considered as the preferred method needs further investigation.
We performed a systematic review and meta-analysis of the prevalence of chest CT findings in patients with confirmed COVID-19 infection. Methods: Systematic review of the literature was performed using PubMed, Scopus, Embase, and Google Scholar to retrieve original studies on chest CT findings of patients with confirmed COVID-19, available up to 10 May 2020. Data on frequency and distribution of chest CT findings were extracted from eligible studies, pooled and meta-analyzed using random-effects model to calculate the prevalence of chest CT findings. Results: Overall, 103 studies (pooled population: 9907 confirmed COVID-19 patients) were meta-analyzed. The most common CT findings were ground-glass opacities (GGOs) (77.18%, 95%CI = 72.23-81.47), reticulations (46.24%, 95%CI = 38.51-54.14), and air bronchogram (41.61%, 95%CI = 32.78-51.01). Pleural thickening (33.35%, 95%CI = 21.89-47.18) and bronchial wall thickening (15.48%, 95%CI = 8.54-26.43) were major atypical and airway findings. Lesions were predominantly distributed bilaterally (75.72%, 95%CI = 70.79-80.06) and peripherally (65.64%, 95%CI = 58.21-72.36), while 8.20% (95%CI = 6.30-10.61) of patients had no abnormal findings and pre-existing lung diseases were present in 6.01% (95%CI = 4.37-8.23). Conclusions: The most common CT findings in COVID-19 are GGOs with/without consolidation, reticulations, and air bronchogram, which often involve both lungs with peripheral distribution. However, COVID-19 might present with atypical manifestations or no abnormal findings in chest CT, which deserve clinicians' notice.
Improved scores of ASFQ after the 12th week showed that the treatment was successful in both groups. Therefore, a vitamin E vaginal suppository may be an alternative to vaginal estrogen in relieving the symptoms of vaginal atrophy in postmenopausal women, especially those not able to use hormone therapy or have low compliance.
Introduction:Regarding to the recent advances in assisted reproductive techniques (ART), twin and multiple pregnancies have increased during past years. Objective:This study was performed to compare obstetrics and perinatal outcomes of dichorionic twin pregnancy following ART with spontaneous pregnancy. Materials and Methods:In this cross-sectional study which was performed in Ghaem Hospital, Mashhad University of Medical Sciences, 107 dichorionic twin pregnancy were enrolled in two groups: spontaneous group (n=96) and ART group (n=31). Basic criteria and obstetrics and neonatal outcomes information including demographic data, gestational age, mode of delivery, pregnancy complications (preeclampsia, gestational diabetes, preterm labor, and intrauterine growth retardation (IUGR), postpartum hemorrhage), neonatal outcomes (weight, first and fifth minute Apgar score, Neonatal Intensive Care Unit (NICU) admission, mortality, respiratory distress, and icterus) were recorded using a questionnaire.Results:Preterm labor, gestational diabetes, and preeclampsia were significantly higher in ART group compared to spontaneous pregnancy group. However, other factors such as anemia, IUGR, postpartum hemorrhage, and intrauterine fetal death (IUFD) were not significantly different between groups. There were no significant differences between groups in terms of neonatal outcomes (weight, 1st and 5th min Apgar score <7, NICU hospitalization, mortality, respiratory distress, and icterus). Conclusion:With regard of significantly higher poor outcomes such as preeclampsia, gestational diabetes and preterm labor in ART group, the couples should be aware of these potential risks before choosing ART.
