Socio-Cultural Appropriateness of the Use of Historic Persian Gardens for Modern Urban Edible Gardens
Historic gardens have the ability to provide several ecosystem services in cities, including provisioning services (i.e., food production). The historic gardens in Iran (known as āPersian Gardensā) have never been considered as places that could be used for food production. As a result, the purpose of this paper is to investigate whether the Iranian historic gardensā spatial and structural layout is suitable for modern urban food gardening. We conducted field studies in six recognized Persian gardens in four provinces of Iran via qualitative analysis according to socio-cultural guidelines drawn from a literature review. The results suggested that combining the elements of formal landscape design, non-edible decorative plants, and traditional artwork would increase the Persian gardensā attractiveness. Regarding encouraging users to become involved in urban gardening, we found that separating productive units containing edible plants from public units using a central meeting spot populated by aesthetic plants and items may attract ordinary visitors who are interested in gardening without disturbing anyoneās activities. Furthermore, the Persian gardensā multifunctionality, aesthetic value, and health-promoting qualities constitute a considerable historic achievement in garden design, making the gardens a suitable model for edible urban gardening. The results of this study can enhance our understanding of the Persian gardensā spatial and structural design and provide practical implications for sustainable urban planning and landscape architecture
Diagnostic Performance of Ultrasonography for Identification of Small Bowel Obstruction: A Systematic Review and Meta-analysis
Introduction: Small bowel obstruction (SBO) is known as a common cause of acute abdominal complaints in the emergency department (ED). The modality of choice for the diagnosis of SBO has not yet been established. This systematic review and meta-analysis aimed to investigate the accuracy of ultrasonography for the diagnosis of SBO.
Methods: Systematic search was performed on five electronic databases including Medline, Scopus, Web of Sciences, Embase, and Cochrane Library, and the retrieval period was from the inception of each database to November 2023. The quality of the included studies were investigated using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2). The pooled values of diagnostic characteristics for ultrasonography were estimated using meta-Disc and Stata statistical software.
Results: Twenty-one studies with a total of 1977 patients were included in the meta-analysis. The pooled estimate for sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under the summary ROC curve of ultrasonography for diagnosing SBO were 0.93 (95% CI: 0.91ā0.95), 0.8 (95% CI: 0.77ā0.83), 5.69 (95% CI: 3.64ā8.89), 0.1 (95% CI: 0.07ā0.16), 83.51 (95% CI: 18.12ā182.91) and 0.96, respectively.
Conclusion: The findings of this meta-analysis showed that the utilization of ultrasonography holds promise as a diagnostic imaging for SBO with high accuracy. However, additional worldwide studies are essential to get more evidence on the value of ultrasonography for the diagnosis of SBO

A systematic review on post-discharge venous thromboembolism prophylaxis in patients with COVID-19
Abstract Background Coronavirus disease of 2019 (COVID-19) is associated with venous thromboembolism (VTE), not only during hospitalization but also after discharge, raising concerns about anticoagulant (AC) use for post-discharge COVID-19 patients. We aimed to systematically review the current literature on the possible benefits or risks regarding extended thromboprophylaxis. Main body We searched related databases from December 1, 2019, to October 6, 2022, including studies on the necessity, duration, and selection of the ideal AC regarding extended thromboprophylaxis for post-discharge COVID-19 patients. The screening of the selected databases led to 18 studies and 19 reviews and guidelines. Studies included 52,927 hospitalized COVID-19 patients, with 19.25% receiving extended thromboprophylaxis. VTE events ranging from 0 to 8.19% (median of 0.7%) occurred in a median follow-up of 49.5 days. All included studies and guidelines, except four studies, recommended post-discharge prophylaxis after an individual risk assessment indicating high thrombotic and low bleeding risk. Studies used risk assessment models (RAMs), clinical evaluation, and laboratory data to identify COVID-19 patients with a high risk of VTE. IMPROVE-DD was the most recommended RAM. Direct oral anticoagulants (DOACs) and low molecular weight heparins (LMWHs) were the most used AC classes. Conclusions Post-discharge prophylaxis for COVID-19 patients is recommended after an individual assessment. The IMPROVE-DD model can help predict VTE risk. After distinguishing patients who need post-discharge AC therapy, DOACs for 30ā35 days and LMWHs for 40ā45 days can be the drug of choice. Further studies, particularly the results of the ongoing randomized controlled trials (RCTs), are required. Also, to properly handle such patients, every physician should consider lifestyle modification in addition to pharmacological treatment for post-discharge VTE prophylaxis
Effect of Obesity Duration and BMI Trajectories on Cardiovascular Disease: A Narrative Review
Abstract Obesity is an important risk factor for cardiovascular diseases (CVDs). It is crucial to understand the impact of its duration due to the more extended exposure period and the higher frequency of overweight/obesity at younger ages. In the last decade, various studies have discovered that the duration of obesity, in addition to its severity, might have an impact. Therefore, this study aimed to summarize the current literature to investigate the effect of body mass index (BMI) trajectories and overweight/obesity duration on cardiovascular outcomes. To retrieve related articles, we searched PubMed, EMBASE, Google Scholar, Web of Science, Scopus, and Cochrane electronic databases. The duration of overweight/obesity is significantly associated with CVDs, especially heart failure and atrial fibrillation. However, there are contradictory results regarding the association between coronary heart disease and stroke with the duration of obesity. Additionally, no association with peripheral vascular disease has yet to be reported. The absence of this association may be brought on by covariates or various follow-up times. Nevertheless, it seems that both stable overweight and remarkably stable obesity increase the risk of CVDs, as does both stable overweight and notably stable obesity. Metrics showing both the severity and the duration of overweight/obesity are more effective than each alone, and it is recommended to be used for assessing the risk of various CVDs. There are few studies in these areas, and studies with more extended follow-up periods, with a wide age range, while adjusting for some specific covariates, are needed

Diagnostic Accuracy of Ultrasonography for Identification of Elbow Fractures in Children; a Systematic Review and Meta-analysis
Introduction: In spite of the results of previous studies regarding the benefits of ultrasonography for diagnosis of elbow fractures in children, the exact accuracy of this imaging modality is still under debate. Therefore, in this diagnostic systematic review and meta-analysis, we aimed to investigate the accuracy of ultrasonography in this regard.
Methods: Two independent reviewers performed systematic search in Web of Science, Embase, PubMed, Cochrane, and Scopus for studies published from inception of these databases to May 2023. Quality assessment of the included studies was performed using Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS-2). Meta-Disc software version 1.4 and Stata statistical software package version 17.0 were used for statistical analysis.
Results: A total of 648 studies with 1000 patients were included in the meta-analysis. The pooled sensitivity and specificity were 0.95 (95% CI: 0.93-0.97) and 0.87 (95% CI: 0.84-0.90), respectively. Pooled positive likelihood ratio (PLR) was 6.71 (95% CI: 3.86-11.67), negative likelihood ratio (NLR) was 0.09 (95% CI: 0.03-0.22), and pooled diagnostic odds ratio (DOR) of ultrasonography in detection of elbow fracture in children was 89.85 (95% CI: 31.56-255.8). The area under the summary receiver operating characteristic (ROC) curve for accuracy of ultrasonography in this regard was 0.93. Egger'sĀ and Begg'sĀ analyses showed that there is no significant publication bias (P=0.11 and P=0.29, respectively).
Conclusion: Our meta-analysis revealed that ultrasonography is a relatively promising diagnostic imaging modality for identification of elbow fractures in children. However, clinicians employing ultrasonography for diagnosis of elbow fractures should be aware that studies included in this meta-analysis had limitations regarding methodological quality and are subject to risk of bias. Future high-quality studies with standardization of ultrasonography examination protocol are required to thoroughly validate ultrasonography for elbow fractures
