Plant foraging is a millennia-old activity still practiced by many people in the Middle East, particularly in the Fertile Crescent region, where several socioeconomic, ecological, and cultural factors shape this practice. This study seeks to understand the drivers of plant foraging in this complex region characterized by highly diverse linguistic, religious, and cultural groups. Our study aims to document the wild plants used by Kurds in Western Iran, identify similarities and differences among Hawraman and Mukriyan Kurdish groups in Iran, and compare our findings with a previous study on the Hawramani in Iraq. Forty-three semi-structured in-depth interviews were conducted in Kurdish villages of Western Iran. The results revealed the use of 44 wild food plant taxa, their preparation, and culinary uses. Among the reported taxa, 28 plant taxa were used by Mukriyani, and 33 by Hawramani. The study revealed a significant difference between the Hawraman and Mukriyan regions in Iran, whereas there is a high similarity between Hawramani Kurds in Iran and Iraq. We found that the invisible cultural border carries more weight than political divisions, and this calls for a paradigm shift in how we perceive and map the distribution of ethnobotanical knowledge.

Key Clinical Message: Arthritis is one of the main presentations of chronic brucellosis, but bursitis and tendon rupture are also caused by brucellosis. Therefore, brucellosis should be considered in the differential diagnosis of arthritis, bursitis, and tendon rupture by physicians. In addition, early diagnosis and treatment are very important in the prevention of disability. Brucellosis is a zoonotic disease common in the Middle East. Manifestations of acute disease are fever, sweating, myalgia, and arthralgia. However, bone joint involvement occurs in 10%–85% of patients, and sacroiliac involvement occurs in up to 80% and vertebral joint involvement in up to 54%. A 57‐year‐old woman was admitted to the hospital of Islamic Azad University on February 26, 2021, with a history of one‐month pain and limited movement of the right shoulder joint with fever for surgery of the shoulder ligament. The standard agglutination titer (Wright) for brucellosis at first was 1/640 and then increased. MRI of the shoulder showed a supraspinatus tendon and anterosuperior labral of the glenoid labrum tear. Although the patient was a candidate for shoulder joint ligament surgery, with a diagnosis of brucellosis, the treatment of brucellosis was prescribed, symptoms disappeared with anti‐brucellosis antibiotic therapy without surgery, and the patient recovered. Supraspinatus tendon and antero superior labral of glenoid labrum tear of the shoulder joint in brucellosis is generally very rare. Failure or delay in the treatment of brucellosis can cause ligament rupture or joint disability. Sometimes, there are no symptoms except osteoarticular manifestations in brucellosis; therefore, brucellosis should be one of the differential diagnoses in osteoarticular diseases.

Background: Considering the importance of scorpions and recognizing the mechanisms of toxicity caused by their medically important species in Iran and adopting the best therapeutic approach based on these mechanisms, this study was performed by reviewing the clinical manifestations of scorpion stings. Methods: The research was conducted by searching for articles and researches in related websites (PubMed, EMBASE, Scopus, Web of Science and CINAHL) and using domestic and international authoritative journals using the keywords of scorpion, clinical manifestations, in a review method. Finally, 104 qualified sources were selected and after reviewing and criticizing these studies, the author's point of view was presented. Results: Clinical manifestations of Scorpion sting toxicity vary due to the existence of two toxic classes of neurotoxins and cytotoxins or hemotoxins in these arthropods in Iran. The number and distribution of species with neurotoxic venom are higher than the scorpions with cytotoxic venom and are reported throughout Iran. Scorpions with cytotoxic venom are mostly widespread in south and southwest of Iran. Conclusion: Treatment and prevention of scorpion stings in Iran and neighboring countries in the Middle East should be planned based on the mechanism of toxicity and the presence of toxic classes with neurotoxic or cytotoxic venoms.

Pteridium aquilinum is one of the most widespread, invasive species in the world, frequently invading disturbed land where it often reduces biodiversity, crop yield, and economic value. Most research on P. aquilinum has been conducted in temperate climates, with limited information available on the spread of the species in areas with semi-arid or Mediterranean climates. Here, we present a regional assessment of the growth of P. aquilinum in Mazandaran Province, northern Iran. P. aquilinum frond and rhizome growth was assessed at 15 sites covering its regional geographic range and a range of elevations, climate types, soil properties and land-uses. Frond phenological change over the growing season was also measured at three sites at different elevations. Results showed that P. aquilinum invasion is not restricted by land-use, elevation, and climate type. P. aquilinum produced 23–42 fronds m−2 with a height of between 78 and 275 cm and 4 to 21 t ha−1 frond biomass and 1.3–18 t ha−1 rhizome biomass. Sites at high elevation had the greatest dormant bud number indicating a potentially greater resistance to control treatment. A novel result was that P. aquilinum biomass produced a bimodal response for soil carbon, nitrogen and pH, but soil phosphorus produced greatest biomass at low concentrations. Phenological analysis of fronds showed a site-dependent, non-linear, sigmoidal pattern for biomass and frond height; asymptotes for frond biomass and frond height reached 1700 g m−2 and 110 cm and became stable after 170 and 180 Julian days, respectively. The phenological results indicate that treatments targeting fronds to control P. aquilinum invasion should be applied after 180 Julian days when maximum transfer of resources from fronds to rhizomes occur. These results provide for the first-time information on the spread of P. aquilinum in northern Iran from a growth and phenological perspective of both fronds and rhizomes and indicate that any human changes in natural ecosystems up to an elevation of 2100 m could facilitate further invasion.

Background: Acute stroke care is complex and requires multidisciplinary networking. There are insufficient data on stroke care in the Middle East and adjacent regions in Asia and Africa. Objective: Evaluate the state of readiness of stroke programs in the Middle East North Africa and surrounding regions (MENA+) to treat acute stroke. Method: Online questionnaire survey on the evaluation of stroke care across hospitals of MENA+ region between April 2021 and January 2022. Results: The survey was completed by 34/50 (68%) hospitals. The median population serviced by participating hospitals was 2 million. The median admission of patients with stroke/year was 600 (250–1,100). The median length of stay at the stroke units was 5 days. 34/34 (100%) of these hospitals have 24/7 CT head available. 17/34 (50%) have emergency guidelines for prehospital acute stroke care. Mechanical thrombectomy with/without IVT was available in 24/34 (70.6%). 51% was the median (IQR; 15–75%) of patients treated with IVT within 60 min from arrival. Thirty-five minutes were the median time to reverse warfarin-associated ICH. Conclusion: This is the first large study on the availability of resources for the management of acute stroke in the MENA+ region. We noted the disparity in stroke care between high-income and low-income countries. Concerted efforts are required to improve stroke care in low-income countries. Accreditation of stroke programs in the region will be helpful. [ABSTRACT FROM AUTHOR]

Modifying human activities is key to achieving land degradation neutrality in rangelands. Rangeland stakeholders encompass different ownership regimes; however, little is known about whether different ownership models benefit or degrade social conditions and ecosystem services in the Middle East. The aim of this research was to determine the effects of Collective or Council ownership on social and ecological indicators in the wintery rangeland of Iran. The study included a social network analysis of the 187 stakeholders in the communal rangelands of Kalat (NE Iran). We considered social network variables such as density, reciprocity, transitivity, geodesic distance and E–I (external–internal) and degree centrality combined with ecological indicators such as condition, forage yield and trend in range condition. The stocking rate was 2.43 AU ha−1 in Council rangelands and 0.94 AU ha−1 for Collective rangelands, with both exceeding recommended carrying capacity. Herbage mass and canopy cover were both higher in the Collective (247 kg/ha; 59%) than Council rangelands (140 kg/ha; 48.3%). Density (47.6% and 48.6%) and reciprocity (54.2% and 53.7%) were higher for Collective rangelands than Council rangelands, but were lower for geodesic distance (1.5 and 1.7–1.8) for trust and collaboration ties. Collective rangelands showed more bridging ties (55%) than the council rangelands (27.5%), suggesting they would be more resilient when problems occur. It concluded that social capital was richer in the Collective rangelands, which creates a willingness in operators to contribute to participatory management of rangelands to improve their condition. Finally suggested new tools and policies, and possible financial and pedagogic support be provided to the Council rangelands to increase social capital and improve outcomes. [ABSTRACT FROM AUTHOR]

This paper presents the results of the new interdisciplinary research done on Leonhard Rauwolf's herbarium with plants from the Middle East, which was later owned by Emperor Rudolf II. Using various sources, it examines how the herbarium came into the imperial collections, Early Modern methods of botanical research as described by Rauwolf in his printed travelogue, and how the illustrations for the printed book were produced from the specimens in the herbarium. The appendix (available in the online version) presents the new corrected botanical identification of the c. 200 plants in the fourth volume of Rauwolf's herbarium, and a correct transcription of the Early Modern Latin and vernacular names Rauwolf collected for these plants.

Arab populations are largely understudied, notably their genetic structure and history. Here we present an in-depth analysis of 6,218 whole genomes from Qatar, revealing extensive diversity as well as genetic ancestries representing the main founding Arab genealogical lineages of Qahtanite (Peninsular Arabs) and Adnanite (General Arabs and West Eurasian Arabs). We find that Peninsular Arabs are the closest relatives of ancient hunter-gatherers and Neolithic farmers from the Levant, and that founder Arab populations experienced multiple splitting events 12–20 kya, consistent with the aridification of Arabia and farming in the Levant, giving rise to settler and nomadic communities. In terms of recent genetic flow, we show that these ancestries contributed significantly to European, South Asian as well as South American populations, likely as a result of Islamic expansion over the past 1400 years. Notably, we characterize a large cohort of men with the ChrY J1a2b haplogroup (n = 1,491), identifying 29 unique sub-haplogroups. Finally, we leverage genotype novelty to build a reference panel of 12,432 haplotypes, demonstrating improved genotype imputation for both rare and common alleles in Arabs and the wider Middle East. Arab populations are relatively understudied, especially their genetic architecture and historical relationship with early founders of the ancient Near East. Here, the authors examine 6,218 Qatari whole genomes, revealing insights on migration, population history and genetic structure of populations across the Middle Eastern region.

Growing anthropogenic impacts on natural and semi-natural ecosystems have created a network of degraded sites throughout the world. These disturbed ecosystems are often colonized by invasive plants such as Pteridium aquilinum, which is one of the most widespread plants worldwide. In northern Iran, P. aquilinum is often found invading newly-created habitats formed after anthropogenic disturbance. This study aimed to assess the relationship between P. aquilinum performance and a range of environmental factors (soils, climate, topography and land-use) in northern Iran. In fifteen sites dominated by P. aquilinum, that spanned the regional distribution of P. aquilinum, we measured its cover, density and biomass. Pteridium aquilinum was found to occur in a variety of land-uses including abandoned agricultural lands, degraded forests and upland rangelands. The performance of P. aquilinum varied significantly between the sites and it performed better in a moderate-Mediterranean climate. Variation partitioning confirmed the importance of climate followed by soil and land-use in explaining the performance of P. aquilinum. Topographic variables did not show any significant effect on P. aquilinum. Both temperature and rainfall affected P. aquilinum performance. Density was correlated positively with early-spring rainfall whereas biomass and cover were found to have positive correlation with temperature. There was also a gradient of soil texture/pH/N/P influencing P. aquilinum. Frond density and biomass were correlated positively with sand content, N and P, but negatively with pH, lime and bulk density. Thus, soil conditions alongside temperature in spring and early summer could explain P. aquilinum cover, but for density, rainfall in early spring was the most important factor, suggesting that in northern Iran P. aquilinum performance appears to be intermediate compared to responses reported for temperate (temperature-controlled) and tropical climates (rainfall-controlled).

Hundreds of blowouts have been reported during the history of the oil and gas drilling activities. These undesired accidents are at the cost of the life of people, in addition to the loss of the equipment and resources; thus, it is important to investigate the root causes of the blowouts in order to prevent them to occur in the future. In 2017, a blowout occurred in a development drilling well in the Middle East. It resulted in several consequences including fatalities, environmental related damages and a subsequent well capping. The incident happened mainly due to insufficient hydrostatic pressure during the tripping operation at the depth of 1132 m. The tripping was decided in order to change the bit when drilling horizontally at the depth of 2610 m. Some details regarding this blowout event will be presented in this paper and the engineering or operational activities and causal factors which led to the incident will be discussed, with the purpose of avoiding similar accidents in the future. Despite analysis of the past kick and blowout data for the whole field, the analysis of the kick volume data of the blowout well indicates that in the period of 2.66 h, the kick converted to the blowout, while in the last 7 min the kick volume reached from 172 to 341.5 bbl which was due to the sudden huge gas expansion. Such an analysis of the root cause factors was rarely made and presented in the region, as was done in this work. • The causal factors which led to a recent blowout in a development oilwell in the Middle East were discussed, with the purpose of avoiding similar accidents in the future. • The causal factors originated from absence of critical review of the drilling program, lack of effective organizational measures over operational practices, improper management of changes, using OBM for drilling gas cap, continuation of operations with defective safety-critical equipment, and lack of proper monitoring of the mud transfers during tripping. • Lack of adherence to basic well control practices was revealed as the main root cause of the incident. • Avoiding similar blowouts is just possible by improving the learning curves from past kicks and blowouts.
