Published: October 2023

The 2022–2023 influenza season in Romania was characterized by high pediatric hospitalization rates, predominated due to influenza A subtypes (H1N1) pdm09 and H3N2. The lowered population immunity to influenza after the SARS-CoV-2 pandemic and the subsequent stoppage of influenza circulation, particularly in children who had limited pre-pandemic exposures, influenced hospitalization among immunosuppressed children and patients with concurrent medical conditions who are at an increased risk for developing severe forms of influenza. This study focused on the characteristics of influenza issues among pediatric patients, as well as the relationship between different influenza virus types/subtypes and viral and bacterial co-infections, as well as illness severity in the 2022–2023 season after the SARS-CoV-2 pandemic. We conducted a retrospective clinical analysis on 301 cases of influenza in pediatric inpatients (age ≤ 18 years) who were hospitalized at the National Institute of Infectious Diseases “Prof. Dr. Matei Balș” IX Pediatric Infectious Diseases Clinical Section between October 2022 and February 2023. The study group’s median age was 4.7 years, and the 1–4 year age group had the highest representation (57.8%). Moderate clinical forms were found in 61.7% of cases, whereas severe versions represented 18.2% of cases. Most of the complications were respiratory (acute interstitial pneumonia, 76.1%), hematological (72.1%, represented by intra-infectious and deficiency anemia, leukopenia, and thrombocytopenia), and 33.6% were digestive, such as diarrheal disease, liver cytolysis syndrome, and the acute dehydration syndrome associated with an electrolyte imbalance (71.4%). Severe complications were associated with a risk of unfavorable evolution: acute respiratory failure and neurological complications (convulsions, encephalitis). No deaths were reported. We noticed that the flu season of 2022–2023 was characterized by the association of co-infections (viral, bacterial, fungal, and parasitic), which evolved more severely, with prolonged hospitalization and more complications (p < 0.05), and the time of use of oxygen therapy was statistically significant (p < 0.05); the number of influenza vaccinations in this group was zero. In conclusion, co-infections with respiratory viruses increase the disease severity of the pediatric population to influenza, especially among young children who are more vulnerable to developing a serious illness. We recommend that all people above the age of six months should receive vaccinations against influenza to prevent the illness and its severe complications.

Viruses in aquatic ecosystems exhibit remarkable abundance and diversity. However, scattered studies have been conducted to mine uncultured viruses and identify them taxonomically in lake water. Here, whole genomes (29–173 kbp) of seven uncultured dsDNA bacteriophages were discovered in Dishui Lake, the largest artificial lake in Shanghai. We analyzed their genomic signatures and found a series of viral auxiliary metabolic genes closely associated with protein synthesis and host metabolism. Dishui Lake phages shared more genes with uncultivated environmental viruses than with reference viruses based on the gene-sharing network classification. Phylogeny of proteomes and comparative genomics delineated three new genera within two known viral families of Kyanoviridae and Autographiviridae, and four new families in Caudoviricetes for these seven novel phages. Their potential hosts appeared to be from the dominant bacterial phyla in Dishui Lake. Altogether, our study provides initial insights into the composition and diversity of bacteriophage communities in Dishui Lake, contributing valuable knowledge to the ongoing research on the roles played by viruses in freshwater ecosystems.

Published: October 2023

Previously, we identified a highly conserved, γ-shaped RNA element (γRE) from satellite RNAs of cucumber mosaic virus (CMV), and we determined γRE to be structurally required for satRNA survival and the inhibition of CMV replication. It remains unknown how γRE biologically functions. In this work, pull-down assays were used to screen candidates of host factors from Nicotiana benthamiana plants using biotin-labeled γRE as bait. Nine host factors were found to interact specifically with γRE. Then, all of these host factors were down-regulated individually in N. benthamiana plants via tobacco rattle virus-induced gene silencing and tested with infection by GFP-expressing CMV (CMV-gfp) and the isolate T1 of satRNA (sat-T1). Out of nine candidates, three host factors, namely histone H3, GTPase Ran3, and eukaryotic translation initiation factor 4A, were extremely important for infection by CMV-gfp and sat-T1. Moreover, we found that cytosolic glyceraldehyde-3-phosphate dehydrogenase 2 contributed to the replication of CMV and sat-T1, but also negatively regulated CMV 2b activity. Collectively, our work provides essential clues for uncovering the mechanism by which satRNAs inhibit CMV replication.

Published: October 2023

Approximately 0.7% of infants are born with congenital cytomegalovirus (CMV), making it the most common congenital infection. About 1 in 5 congenitally infected babies will suffer long-term sequelae, including sensorineural deafness, intellectual disability, and epilepsy. CMV infection is highly species-dependent, and the rhesus CMV (RhCMV) infection of rhesus monkey fetuses is the only animal model that replicates essential features of congenital CMV (cCMV) infection in humans, including placental transmission, fetal disease, and fetal loss. Using experimental data from RhCMV seronegative rhesus macaques inoculated with RhCMV in the late first to early second trimesters of pregnancy, we built and calibrated a mathematical model for the placental transmission of CMV. The model was then used to study the effect of the timing of inoculation, maternal immune suppression, and hyper-immune globulin infusion on the risk of placental transmission in the context of primary and reactivated chronic maternal CMV infection.
Influenza Vaccination of Romanian Medical Students and Resident Physicians—A Matter of Accessibility
Authors: Bălan Ana , Ruță Simona Maria
Published: October 2023

In Romania, influenza vaccination of healthcare professionals is recommended, but not mandatory. This study aims to investigate the attitudes and behaviors of medical students and resident physicians—the youngest healthcare professionals—towards influenza immunization, focusing on the barriers and facilitators, as well as on the impact of the COVID-19 pandemic. An anonymous online survey was conducted during the 2021/2022 influenza season, with responses from332 medical students and resident physicians. The majority (73.5%) were not vaccinated against influenza (68% of the students, 52.3% of the residents), although they were vaccinated against COVID-19 (94% students, 94.8% resident physicians) and believed that the pandemic positively influenced their attitude towards influenza vaccination. Vaccine accessibility (p < 0.001) and the necessity to pay for vaccination (p < 0.001) were identified as barriers in both groups, while lack of recommendation from a medical professional/teacher was significant only for students (p < 0.001). Forgetfulness and lack of prioritizations were the most cited reasons for not being vaccinated. These barriers could be diminished through proactive recommendation and simplification of the vaccination process, with accessible vaccination centers and implementation of vaccine reimbursement policies. Improved vaccination rates in young medical professionals are of the utmost importance both in their professional settings and as a model for the general population.

Published: October 2023

During the COVID-19 vaccination campaign, Germany, like other high-income countries, introduced mass vaccination centers for administering vaccinations. This qualitative study aimed to examine the role that these novel, temporary government healthcare structures played in a mass immunization roll-out and how they can be optimally deployed. In addition, learnings for general emergency preparedness were explored. A total of 27 high-level policymakers responsible for planning and implementing the COVID vaccination campaign at the national and state level in Germany were interviewed in May and June 2022. The semi-structured interviews were analyzed using thematic analysis. Interviewees indicated that mass vaccination structures played an essential role with respect to controllability, throughput, accessibility and openness in line with the key success criteria vaccination coverage, speed and accessibility. In contrast to the regular vaccination structures (private medical practices and occupational health services), public administration has direct authority over mass vaccination centers, allowing for reliable vaccine access prioritization and documentation. The deployment of vaccination centers should be guided by vaccine availability and demand, and vaccine requirements related to logistics, as well as local capacities, i.e., public-health-service strength and the physician density, to ensure effective, timely and equitable access. Improvements to the capacity use, scalability and flexibility of governmental vaccination structures are warranted for future pandemics.

Published: October 2023

To achieve maximum efficacy, vaccines, such as subunit, recombinant, and conjugate vaccines, necessitate the incorporation of immunostimulators/adjuvants. Adjuvants play a vital role in bolstering and extending the strength of the immune response while also influencing its type. As antigen and adjuvant formulations become more intricate, it becomes imperative to establish a well-characterized and robust formulation to ensure consistent and reproducible outcomes in preclinical and clinical studies. In the present study, an HPV bivalent vaccine was developed using a BC02 adjuvant in conjunction with HPV 16 and 18 L1 VLP antigens produced from an E. coli expression system. The study involved evaluating the adjuvant formulation and in vivo immunogenicity in mice. Remarkably, a medium-dose of BCG-CpG-DNA combined with a low-dose of aluminum hydroxide substantially enhanced the immunogenicity of HPV16 and 18 VLPs, resulting in improved cellular and humoral immune responses.
Metabolic Syndrome Is Associated with Poor Omicron Infection Prognosis While Inactivated Vaccine Improves the Outcome of Coronavirus Disease 2019 among Chinese Inhabitants: A Retrospective Observational Study from a Chinese Municipality

Published: October 2023

Coronavirus disease 2019 (COVID-19) and metabolic syndrome (MetS) are currently highly prevalent diseases worldwide. Studies on clinical outcomes of patients with Omicron and MetS, especially after vaccination with an inactivated vaccine are limited. Herein, we explored the relationship between MetS and the outcome of Omicron infection. Study Design: This was a retrospective observational study. Methods: This study recruited 316 individuals with Omicron infection. The inpatient data from between 8 January and 7 February 2022 were obtained from designated isolation hospitals in Tianjin, China. Hierarchical and multivariable analysis was conducted on age, gender, number of complications, and vaccination status. Results: Among the 316 study participants, 35.1% were diagnosed with MetS. The results showed that MetS was strongly associated with Intensive Unit Care (ICU) admission, Polymerase Chain Reaction (PCR) re-positivity, and severe COVID-19. The ICU admission rates of the unvaccinated individuals, those who received two-dose and full vaccination (3 doses), were 66.7%, 19.2%, and 0, respectively (p < 0.01). Two-dose and three-dose vaccinations significantly reduced PCR re-positivity. Conclusions: In summary, MetS increases the risk of ICU admission, PCR re-positivity, and severe COVID-19. MetS is a composite predictor of poor outcomes of Omicron infection. Two shots of inactivated vaccine, specifically three doses, effectively protect against Omicron even in the high-risk group.

The application of nanotechnology in aquaculture for developing efficient vaccines has shown great potential in recent years. Nanovaccination, which involves encapsulating antigens of fish pathogens in various polymeric materials and nanoparticles, can afford protection to the antigens and a sustained release of the molecule. Oral administration of nanoparticles would be a convenient and cost-effective method for delivering vaccines in aquaculture while eliminating the need for stressful, labour-intensive injectables. The small size of nanoparticles allows them to overcome the degradative digestive enzymes and help deliver antigens to the target site of the fish more effectively. This targeted-delivery approach would help trigger cellular and humoral immune responses more efficiently, thereby enhancing the protective efficacy of vaccines. This is particularly relevant for combating diseases caused by pathogens like Aeromonas hydrophila, a major fish pathogen responsible for significant morbidity and mortality in the aquaculture sector. While the use of nanoparticle-based vaccines in aquaculture has shown promise, concerns exist about the potential toxicity associated with certain types of nanoparticles. Some nanoparticles have been found to exhibit varying degrees of toxicity, and their safety profiles need to be thoroughly assessed before widespread application. The introduction of nanovaccines has opened new vistas for improving aquaculture healthcare, but must be evaluated for potential toxicity before aquaculture applications. Details of nanovaccines and their mode of action, with a focus on protecting fish from infections and outbreaks caused by the ubiquitous opportunistic pathogen A. hydrophila, are reviewed here.

Authors: Iqbal Muhammad Shahid , Khan Salah-Ud-Din , Qamer Shafqat , Vohra Saeed
Published: October 2023

The current systematic review presents COVID-19 vaccine hesitancy among parents for their children in Middle Eastern countries. Moreover, the vaccine acceptance rate of parents from the Middle East and the factors effecting the acceptance rate were reviewed and summarized. For this systematic review, basic electronic academic databases (Scopus, Science Direct, ProQuest, Web of Science and PubMed) were used for the search, along with a manual search on Google Scholar. This systematic review was conducted by following the “Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)” guidelines. Moreover, utilizing the framework of the PECO-S (Population Exposure Comparison Outcome Study design), various observational studies were recruited for this review. Out of 2123 studies, 25 studies meeting the inclusion criteria were included in the current review. All of the included studies were about parental vaccine hesitancy for COVID-19 in Middle Eastern countries and published during 2020–2022. Overall, 25 research papers comprising 10 different Middle Eastern countries with 33,558 parents were included. The average age of parents was 39.13 (range: 18–70) years, while the mean age of children was 7.95 (range: 0–18) years. The overall hesitancy rate was 44.2% with a SD of ± 19.7. The included studies presented enhanced COVID-19 vaccine hesitancy among parents in Middle Eastern countries. The lower vaccine acceptance rate among parents was mainly because of a fear of the potential side effects. Furthermore, the lack of information regarding vaccine safety and efficacy, the fear of unreported side effects and concerns about the authenticity of vaccine development and preparation were the predictors of parental COVID-19 vaccine hesitancy among Middle Eastern countries.

The article provides the data on the ancient aboriginal population stay on Wrangel Island. The N. N. Dikov archaeological expedition to the island and his discovery of the Chyortov Ovrag Paleoeskimo site on the coast of Krasin Inlet (Somnityelnaya Bay area) is comprehensively reported. Brief information about the subsequent archaeological work at this site is given. It has been established that the appearance of the Paleoeskimo tradition of about 3.5 kyr in the Far North-East of Asia is associated with the migration of Arctic America's Paleoeskimo groups to the Bering Strait zone. An important conclusion made by N. N. Dikov is that the Wrangel Paleoeskimo culture tends to the Pacific coastal cultures and, apparently, is a part of the oldest single and broad cultural layer, which served as a basis for many North Pacific coastal cultures Today's researchers consider Paleoeskimo the settlement of Unenen, discovered in the south of the Chukchi Peninsula, the Dolakhtin sites in the Northwestern Beringomorye, the Tokarev culture in the Northern Priokhotye. The Paleoescoaleutian tradition had a certain influence on the development of the Tarya culture of the II-I millennia BC in Kamchatka.

Environment changes in the northwestern part of the Sea of Japan and adjacent land during last 21.0 kyr was reconstructed based on the analysis of pollen and diatom data with a high temporal resolution. Relatively dry climate caused a wide distribution of forest-steppe landscapes in the region between 21.0 to 16.6 ka. Boreal forests covered mountain slopes. Broad-leaved trees survived in refugia located in lower mountain belts. The low sea level during the Last Glacial Maximum (LGM) changed the general patterns in the sea circulation and longshore current directions, which transported the waters formed in the shallow areas of the northwestern and northern parts of the Sea of Japan. A slight increase in sublittoral benthic diatoms indicates the lowered sea level during the LGM. Occurrence of Betula indicates the start of warming after 18.5 ka; it was interrupted by the cold event Heinrich 1 and marked by the spread of coniferous Larix, Picea, and sphagnum bogs. The beginning of late glacial climatic amelioration Bølling-Allerød (BA) is contributed to dispersal of Quercus and Polypodiaceae ferns. The distribution of conifers Larix and Picea as well as of sphagnum bogs is correlated with the Younger Dryas (YD) cooling. Significant changes in vegetation occurred in the Holocene. The high percentage of sublittoral planktonic diatoms reflects a gradual rise in sea level during the BA and YD. A greater component of oceanic diatom species in the Holocene indicates the inflow of the Pacific waters through both the Tsushima and Tsugaru straits. Some increase in the participance and species diversity of relatively warm-water diatoms was noticed in the warming periods. The study of pollen and diatom records demonstrates a clear response to climatic fluctuations and changes in the Sea of Japan level in the Late Pleistocene and Holocene.

Palynological analysis of sediments from Lake El'gygytgyn, formed during oxygen-isotope stages 50-59, documents the changes of cold stages, interstades and interglaciations. Ten pollen zones were identified and correspond to the interval 1.4920-1.6975 million years ago. This interval includes the Gilsa magnetic event (1.68 Ma), which is an important chronological landmark. Larix pollen appears in the palynological spectra of all stages. The presence of this taxon during warm climates indicates that larch forests established in the areas of the Anadyr Plateau and Lake El'gygytgyn and replaced the larch forest-tundra, which is characteristic of the cold stages. The warmest climatic conditions occur in pollen zone 6 (MIS55) and are in the range of 1.4920-1.6975 million years ago. Vegetation in the period of maximum cooling is characterized by pollen zones 7-10 (MIS50 - MIS54). The interval 1.4920-1.6975 million years ago represents the last step in the completion of the Quaternary vegetation history from a unique region of Arctic Siberia.

Expert assessment has been performed using the cartographic method in a key area of the Badjal Rige southwestern spurs. The basic natural regularities of the soil and vegetation cover have been identified, including heterogeneity and contrasting change of soil and vegetation complexes within the limits of vertical zoning; belt-zone differentiation (alpine, subalpine, and taiga); wide distribution of corroms; maximum diversity and high dynamism of floodplain soil and plant complexes. The article presents a 1 : 40,000-scale vegetation map; it is based on the ecological and phytocenotic classification of vegetation. The main mapped units are association groups and their combinations. The legend reflects 13 divisions of the vegetation cover. Corroms occupy the largest areas (24.9 %). The subalpine zone vegetation makes 20.9 % of the total area. Mountain taiga forests take 32.9 % of the total mapped territory, including spruce forests (7.3 %), larch forests (21.9 %), and birch-larch forests (3.7 %). Larch woodlands are responsible for slightly less than 3 % of the territory; sphagnum oligotrophic bogs, for 0.5 %. Floodplain forests are spread over the area of 12.5 %; that includes spruce forests (4.8 %), chosenia-poplar-larch forests (4.5 %), and poplarlarch forests (3.2 %). 4.4 % of the area is pebbled. There are 5 types and 13 subtypes of soils represented in the soil cover. Dystric histosols and leptic folic histosols form the soil background. Soils are characterized by the presence of organogenic-coarse humus or dry peaty horizons. Organic matter content is high or very high. The reaction of the soil solution varies from very acidic to acidic. Based on the vegetation map, soil areas are roughly quantified. In terms of the set of soil and plant complexes as well as their regular change in vertical zoning, the area under discussion is the reference territory. Represented here is the Okhotsk type of land cover zoning, which is typical for the Far East with its monsoonal climate.

On the Arman basalt plateau, 130 species of vascular plants occur on the area about 3.5 km2 at altitudes of 900-1250 m ASL. Two of them, Caragana jubata and Magadania olaënsis, are included in the Red Data Book of Magadan Oblast, the latter is introduced in the Red Data Book of the Russian Federation. Almost all plant species occurring on Mt. Bazaltovaya are characteristic for the Ola basalt plateau. Despite its small area, the Arman plateau is a floristic refuge with the compositionally and geographically heterogeneous flora. For its protection, it is necessary to increase the area of the Bazaltovy natural geological sanctuary.

The article presents the data on structures of the nucleotide sequence fragments of the 12S ribosomal RNA gene (12S rRNA) for 19 tetrathyridia specimens of the genus Mesocestoides Vaillant, 1863 from representatives of 10 insectivore and rodent species from different regions of RussiaТs East and Alaska (USA). For the first time, the participation of three shrew species in the life cycle of Mesocestoides has been established. Nucleotide sequence fragments of the 12S rRNA gene have been analyzed phylogenetically. The researched tetrathyridia do not assumingly belong to any of the confirmed species of the genus; however, the identity of five of the 12S rRNA sequence fragments from micromammalian tetrathyridia and two nucleotide sequences of 12S rRNA from carnivorous mammals of Mongolia, placed in GenBank, has been established.
Традиционное летоисчисление эвенов и коряков Магаданской области (в связи с современными этническими праздниками встречи Нового года)

The calendar systems of two indigenous peoples living in Magadan Oblast (Evens and Koryaks) have been comparatively studied. The theory of ethnic community adaptation to the natural and socio-cultural environment served as a methodological basis for the research. Traditional Even and Koryak annual cycles determined by their origins, types of economic activities, and ecological factors, are discussed. Revealed as well are differences in chronlogical practices resulted from the degree of foreign ethnic influences and borrowings. The author shows that the Evens experienced a strong Russian cultural influence and most of them joined the Russian Orthodox church; therefore, the Even culture embraces some intermittent chronological systems, i. e. the phenological and the Russian Orthodox calendars as well as the human joints calendar. Until recently, Koryaks remained votaries of their traditional religion; however, their annual calendar is complicated by the dualism of their economic and cultural structure (reindeer and coastal groups). The author concludes that Evens and Koryaks had a wide range of options for counting the beginning of a new (primarily economic) year. The article shows the traditional chronology refraction in the modern ethnic New Year holidays (Hebdenek and Tuygivin).

Published: October 2023

The Indonesian government issued Presidential Regulation of the Republic of Indonesia Number 72 of 2021 concerning the acceleration of stunting reduction with a prevalence target of 14% by 2024. Stunting has now become a national issue and is of particular concern to the government to overcome the risks it poses. One action that can be taken to prevent stunting is to provide intervention to families at risk of stunting. This intervention is carried out in the form of clustering of sub-districts or villages consisting of babies under two years (baduta), babies under five years (toddlers), and pregnant women with inadequate environmental aspects (sanitation and clean water). Based on this, this research aims to conduct a cluster analysis of sub-districts or villages that are at risk of stunting. The cluster analysis method uses the K-Mean algorithm with reference to 3 clusters, namely low, medium, and high. This research uses a dataset of 71 sub-districts or villages that are at risk of stunting. The research results show that the performance of the K-Means method in cluster analysis produces 32 low-risk sub-districts or villages, with a percentage of 45.07%, 36 medium risks with a percentage of 50.70%, and 3 high risk with a percentage of 4. 23%. Based on these results, this research can contribute to the relevant government in dealing with the spread of stunting
Increasing Risk of Silent Disaster in Uttarakhand Himalaya: An Example from Higher Himalaya
Authors: KHANDURİ Sushil , SAKLANİ Rajendra Dutt , CHETRY Bishnu Maya
Published: October 2023

Land subsidence is an abrupt and silent disaster worldwide caused by various factors such as tectonics, nature of rocks and climatic variability etc. It is directly triggered by anthropogenic activities. The Uttarakhand Himalayan province in India has witnessed several earthquakes, landslides, avalanches, droughts, and flash floods/floods in the recent past. Among these incidences landslides frequently occurs in the Himalayan region, particularly during the monsoon season. Seismically, this region falls in seismic zones V and IV due to which area witnesses frequent earthquakes. An attempt was made for preparation of an inventory of land subsidence across the state of Uttarakhand to determine the key factors that are responsible for land subsidence. Previous studies and field evidences suggests that land subsidence events mainly occur due to several factors such as carbonate rocks, topography, tectonics, seismicity, climate, flash floods/floods and reservoir drawdown effect in this region. Furthermore, anthropogenic activities such as mining, underground water, unscientifically civil constructions, inadequate drainage, heavy load on ground/slope, and modification of slope for infrastructure developments aggravates the problem. This study also highlights the problem of ongoing chronic land subsidence in Joshimath town which is situated over an old landslide mass as well as its proximity to Vaikrita Thrust.
سلطـة المشغـل في تعديـل عقـد الشغـل في ضوء العمـل القضائـي
Authors: موقوش سعيد
Published: October 2023

إن عقد الشغل كغيره من العقود يخضع للأحكام العامة التي تحكم العقد، ومن أهم هذه الأحكام قاعدة العقد شريعة المتعاقدين، التي تمنع أياً من طرفي العقد الانفراد بتعديله وذلك حماية لاستقرار التعامل.
إلا أنه ونظراً لاحتمال تغير الظروف التي عاصرت إبرام العقد فقد يلجأ المشغـل إلى تعديل العقـد بالإرادة المنفردة، لذلك لابد من إيجاد وسيلة تكفل للمشغـل إجراء التعديل دون الاصطدام بالقواعد العامة.
تبرز أهمية هذه الدراسة في بيان الحدود التي يستطيع المشغـل إجراء التعديل ضمنها مع المحافظة على حقوق الأجيـر المكتسبة وذلك من خلال التمييز بين التعديل الجوهري والتعديل غير الجوهري، ومن ثم بيان أساس سلطة المشغـل في التعديل واستعراض أهم صور التعديل والآثار المترتبة عليه.

استحدث المنظم السعودي شكلًا جديدًا للشّركات التجارية، وذلك بموجب نظام الشّركات الجديد الصادر بالمرسوم الملكي رقم (م/132) وتاريخ 1/ 12/ 1443هـ، وأسماه "شركة المساهمة المبسطة". وطبقا للأحكام المتعلقة بها الواردة في هذا النظام، فإنّ الشركاء في هذا النوع من الشركات التجارية يمتعون بقدر واسع من الحرية التعاقدية في تنظيم الأحكام والمسائل المتعلقة بها، كما وأنها تمتاز بسهولة تكوينها ومرونة في تنظيمها. ويهدف هذا البحث إلى دراسة التنظيم القانوني لتأسيس شركة المساهمة المبسطة، وتبيان قصد المنظم من إضافة هذا النوع الجديد ضمن الشركات التجارية، وإبراز ميزات وخصائص هذه الشركة وشروط تأسيسها. واتبع البحث المنهج الوصفي والتحليلي من خلال تحليل نصوص نظام الشركات السعودي ومقارنتها بالتشريع الفرنسي على اعتبار أن هذا الأخير هو أول من أخذ بهذا النوع من الشركات وأن أغلب الأحكام المتعلقة بها مستمدة منه. وقد توصلت هذه الدراسة إلى عدة توصيات من أبرزها ضرورة تعديل النصوص التي تجيز للشركة طرح أسهمها للاكتتاب العام، وحظر طرح أسهمها للتداول من خلال الأسواق المالية، وذلك أسوة بالمشرع الفرنسي الذي أوجد هذا النوع من الشركات، حيث حظر إمكانية تجميع رأس مالها من خلال الاكتتاب العام، وحظر تداول أسهمها من خلال الأسواق المالية، كما قصر المشرع الفرنسي هذا النوع من الشركات على مشروعات محددة، وحظر عليها ممارسة بعض الأغراض التي تمارسها الشركة المساهمة، وذلك حتى لا تكون بديلا عنها ومنافسة لها.
