In an effort to improve the performance and competitiveness of Micro, Small and Medium Enterprises (MSMEs), the synergy of environmentally friendly practices with digital marketing is an important focus. The community service carried out highlights Warung Makan Mbokcentil, an MSME that is not yet accustomed to environmentally friendly practices and is less than optimal in digital marketing strategies. Through community service initiatives, efforts are being made to promote environmentally conscious practices, recommending the implementation of packaging made from cassava leaves—commonly known as cassava bags, as a more environmentally friendly way of doing business at Warung Makan Mbokcentil. At the same time, community service activities strengthen digital marketing efforts by introducing barcode scanning for complaint services. This innovation facilitates fast and efficient customer feedback, thereby driving continuous improvement in the quality of Warung Makan Mbokcentil's services. In addition, strategic use of social media across related platforms is used to expand market reach and strengthen customer engagement. This community service activity uses interview, observation and mentoring methods. The results of the service underline the positive impact of the synergy of environmentally friendly practices and digital marketing at Warung Makan Mbokcentil. This collaborative approach makes a significant contribution to increasing operational efficiency, enhancing brand image and supporting environmental sustainability. Additionally, it has proven to play an important role in expanding market share through increasing presence on social media platforms.

Published: January 2024

Background: Remote collaborative care (ReCC) is a legally recognized form of telehealth that facilitates communication between physicians. This study aimed to analyze the effectiveness of ReCC services and establish a foundation for the usefulness and effectiveness of ReCC.Methods: This retrospective cohort study utilized data from the Digital Healthcare Information System (DHIS) managed by the Korea Social Security Information Service. We extracted data on patients who were registered from January 2017 through September 2023 to investigate the effects of various factors.Results: A total of 10,407 individuals participated in the remote collaborative consultation service provided by the DHIS. Of these participants, those aged ≥80 years represented 39.2% (4,085 patients), while those aged 70 to 79 years comprised 36.9% (3,838 patients). The conditions treated included hypertension, affecting 69.2% (7,203 patients), and diabetes, affecting 21.1% (2,201 patients). Although various measurement items were recorded, most data beyond blood pressure readings were missing, posing a challenge for analysis. Notably, there was a significant reduction in blood pressure that was sustained at follow-up intervals of 1, 3, 6, and 12 months post-baseline (all P<0.05).Conclusions: Owing to the lack of data, follow-up assessments for conditions other than hypertension proved to be challenging. Medical staff should increase their focus on and engagement with the system. Remote consultations have demonstrated efficacy in managing hypertension in medically underserved areas, where access to healthcare services is often limited. This suggests the potential for expanded use of remote chronic care in the future.
Recent evidence on target blood pressure in patients with hypertension
Authors: Kim Hack-Lyoung
Published: January 2024

Hypertension is a significant risk factor for a variety of cardiovascular diseases, including stroke, coronary artery disease, heart failure, and peripheral arterial disease. Achieving and maintaining a specific target blood pressure (BP) is crucial for effectively reducing the risk associated with these conditions. This involves customizing treatments to meet the individual needs of patients with hypertension, ensuring that each person receives the most appropriate care for their particular circumstances. Previously, based on the findings from the ACCORD (Action to Control Cardiovascular Risk in Diabetes) study conducted over the past decade, the target BP for patients with hypertension was set at <140/90 mmHg, regardless of the patient's risk profile. However, new insights from reanalyzed data of studies such as the SPRINT (Systolic Blood Pressure Intervention Trial), the STEP (Strategy of Blood Pressure Intervention in the Elderly Hypertensive Patients) study, and ACCORD subgroup reanalysis have led to a change in this approach. These studies support a more aggressive target BP of <130/80 mmHg, especially for high-risk patients. The purpose of this article is to offer a thorough review of these updated recommendations and to explain the reasoning behind the revised target BP guidelines for individuals with hypertension.
Methodology for assessing the food attractiveness of feeding objects on the example of juvenile Australian red claw crayfish
Authors: Borisov R. R. , Nikonova I. N. , Kovatcheva N. P.
Published: January 2024

The aim of the work: to identify behavioral responses that make it possible to characterize the food attractiveness of potential feeding objects for juveniles of the crayfish Cherax quadricarinatus.

Used methods: the study was conducted on the juvenile Australian red-clawed crayfish C. quadricarinatus, in the aquarium room of aquaculture invertebrate department at VNIRO. 11 types of feeding objects of plant and 4 types of animal origin were studied, as well as TetraWaferMix compound feed as a control. A total of 616 experiments were performed.

Newness: on the juveniles of the Australian red-clawed crayfish C. quadricarinatus, the methodology for assessing the nutritional attractiveness of feeding objects by the nature of behavior during feed consumption was tested.

Result: the experiments conducted showed that a large proportion of individuals who threw, crumbled, held food with their oral limbs for a long time without attempting to mechanical processing it or did not eat the food, indicates its unsatisfactory nutritional qualities. The time spent by crayfish on eating food depends on the hardness of the proposed components, the rate of their softening in water, the size of individuals and therefore cannot directly characterize the nutritional attractiveness of the feed. Most of the proposed forage objects (11 out of 15) had attractive nutritional characteristics for juveniles of C. quadricarinatus crayfish. The most active juveniles consumed animal feed (larvae of Chironomus sp. and Hermetia illucens, squid meat, Gammarus sp.), and among the feeds of plant origin, the seeds of oats, wheat and fried buckwheat, as well as beets and potatoes had the greatest attractiveness.

Published: January 2024

The aim of the study was to develop therapeutic measures to combat bacterial hemorrhagic septicemia of fish using a complex of antibacterial drugs “Levofloxacin” and “Chlortetracycline”.

Methods used: experiments were carried out in aquarium conditions on juvenile carp and hybrids «Siberian sturgeon×Kaluga» (hereinafter hybrid SO×K) infected with a mixed culture of pathogens: highly pathogenic strains of Aeromonas sp., strains of R.R. Acinetobacter and Citrobacter. In the experiment, 2 variants of the use of antibiotics for a course of 7 days were tested. Bacteriological seeding of fish parenchymal organ samples was carried out on nutrient and differential diagnostic media.

Novelty: it consists in working out the scheme of application for fish of a complex of new antibiotics for aquaculture.

Results: the results of the evaluation of the therapeutic effect of antibiotics “Levofloxacin” + “Chlortetracycline” in the treatment of bacterial hemorrhagic septicemia are presented. The cessation of fish death was noted the next day after the start of therapy. Positive results were obtained in carp — with a combination of levofloxacin at a dosage of 1000 mg/kg of ichthyomass and chlortetracycline — 100 mg/kg of ichthyomass, in a hybrid of SO×K — 500 mg/kg of ichthyomass of levofloxacin + 200 mg/kg of ichthyomass of chlortetracycline. Evaluation of their combinations with different dosages did not show 100% effect. The difficulties of therapy have been identified, which are associated with the spread of strains of microorganisms resistant to antibacterial drugs.

Practical significance: the developed method of therapy is effective, reduces the damage from the disease and can be recommended when developing measures to combat bacterial hemorrhagic septicemia in fish in aquaculture.

Authors: Bogdanova V. A. , Kostyunichev V. V. , Alexandrov A. A.
Published: January 2024

The purpose of the work: to estimate fish breeding indicators of three hybrid forms of whitefish in comparison with parental species when grown in cage aquaculture.

Methods used: the production and cultivation of hybrids and parental species were carried out using standard technology for whitefish from November 2021 to May 2022. We have studied the survival and growth rate of fingerlings, and we also conducted a comparative assessment of the exterior of yearlings using factor and cluster analyses.

Novelty: for the first time, three hybrid forms of peled and parent species (peled, muksun, broad whitefish, nelma) were grown in cages, and a comparative analysis of survival, growth and morphology of hybrids and parent species was performed.

Results: all hybrid forms occupy an intermediate position in terms of growth rate, surpassing the maternal species (peled), yielding to the paternal ones. The best results in terms of weight and linear growth among hybrids were noted in pelchir. In terms of survival, oneyearlings of all hybrids show the effect of heterosis, although at the stage of larvae and early juveniles, the superiority in survival of hybrid forms over the parental pair was noted only in pelnelm. The survival rate of hybrid eggs, as well as the survival rate of pelchir and pelmuk at the early stages of cultivation, had intermediate values — lower than that of peled, but significantly higher than that of paternal species. The lowest survival rate of eggs among hybrids is shown in pelchir. The peled has the most significant morphological differences from other pure species and hybrid forms used in the experiment, all hybrid forms show more similarity with the paternal species.

Practical significance: results provide a potential assessment of whitefish hybrids for the prospect of their use in commercial aquaculture.

Authors: Novikov M. A. , Gorbacheva E. A. , Kharlamova M. N.
Published: January 2024

This study aims to identify the total mercury content in the muscle and hepatopancreas of the main commercial crustaceans from the Barents Sea.

The material for this study was the samples of red king crab Paralithodes camtschaticus and northern shrimp Pandalus borealis caught during the research cruises conducted by “PINRO” from 2012 to 2022. This study examines the samples of muscle collected from crustaceans, as well as the samples of hepatopancreas collected from the red king crab.

Novelty: This study involves abundant data that was used to make the first comparative analysis of the Hg concentration in red king crab and northern shrimp. A significant similarity in the levels of Hg content in the muscle of shrimp and crab at the mean level was shown. The paper provides maps of average Hg content in the studied species for the entire Barents Sea.

Methods used: the total mercury content in the samples was estimated by flameless atomic absorption spectroscopy analysis using Shimadzu Cold Vapor Atomic Absorption Spectrophotometer (Japan). Statistical data processing and charting were done using MS Excel and application software package of Statistica 13.

Results: The paper shows that the average concentration of Hg in the muscle and hepatopancreas of the studied hydrobionts did not exceed 0.2 mg/kg of wet weight that is the acceptable concentration established by sanitary standards. The content of Hg in the red king crab’ hepatopancreas was about 2 times higher than in the muscle. The paper makes an assumption on the species-specifity of Hg content in the red king crab’ muscle. The Hg content in the muscle of P. borealis is strongly related to its fattiness. The paper suggests calculated background levels of the total Hg concentration in the muscle of P. camtschaticus and P. borealis from the Barents Sea.

Practical relevance: The results obtained were used to establish the safety compliance of commercial crustaceans with the requirements adopted in Russia.

Authors: Vilkova O. Yu. , Burmistrov E. V. , Sveshnikov Yu. A.
Published: January 2024

The purpose: to obtain modern data on the distribution, abundance, size composition and biological state of the sturgeon in the middle reaches of the Lena River.

Material: data of scientific accounting survey using bottom drift nets in summer 2022.

The results: Siberien sturgeon is dstributed irregularly on a 400‑kilometer stretch of the river from the city of Yakutsk to the Vilyui River, with the highest average density near the Vilyui River mouth 163 ind./km2, while sturgeon densities in the areas of Yakutsk and the Aldan River mouth were 71 and 44 ind./km2 respectively. The highest density of fish with the smallest average size in the area near the Vilyui mouth indirectly indicates the presence of a separate herd in the Vilyui River. The average density of fish over the entire 400‑km area was 93 ind./km2. The sturgeon length to the end of the middle rays (ac) was from 21 to 86 cm; on average 43.4 ± 10.7 cm. The modal size class for the sturgeon in catches in 2022 was 41–50 cm (44% of the total catch). The fish weight ranged from 40 to 3800 g. The average weight of individuals was 0.557. More than 80% of fish from all catches weighed up to 700 g. The weight of fish with a length ac 62–71 cm ranged from 0,400 to 1.415 kg, on average 1.0 kg. There were only 2.5% of commercial individuals in the total harvest. Sexually mature females were noted only near the Aldan mouth, where their share was 11% that may indicate the presence of spawning grounds in its channel. In the sample of fish that underwent a complete biological analysis (one third of the catches), sexually mature males were not observed. Estimated number of sturgeon: in Yakutsk city area — 17000 ind., in the Aldan mouth area — 47000 ind., in the Vilyui mouth area — 55000 ind. The total number of Siberian sturgeon on a 400‑kilometer stretch of the Lena River was at least 120000 ind. The state and structure of sturgeon population corresponds to the average statistical retrospective data.

Practical value: the results obtained will improve the efficiency of assessing the distribution and stock of sturgeon in the Lena River.

Authors: Mitrushkina D. K. , Kiseleva M. N.
Published: January 2024

The purpose of the review is to summarize modern data on the phylogenetic relationships of two sturgeon species, the North American Atlantic sturgeon Acipenser oxyrinchus and the European Atlantic sturgeon A. sturio, living in the Baltic Sea, due to the complete loss of A. sturio and the presence of a small number of individuals of A. oxyrinchus.

Methods used: comparative analysis of modern literature data, a deconstruction method in which studies reflecting the molecular genetic characteristics of species have been carefully selected.

The result of the review is structured data on molecular genetic studies of two sturgeon species. Combining research methods conducted with these species in one review.

Significance: The results of the generalization are necessary for organizing measures to restore the lost population of sturgeon that lived in the water bodies of the Baltic Sea basin and was lost due to overfishing and changes in the habitat. A systematic approach to the molecular genetic labeling of fish both in the wild and in fish farms will ensure the control of the released juveniles, which will facilitate further research in this field of science.

Authors: Listyaningrum Trisna Avi , Toifur Moh.
Published: January 2024

Penggunaan pupuk anorganik akan memberikan suhu yang lebih panas daripada menggunakan pupuk organik. Hal ini disebabkan oleh kandungan hara yang ada di pupuk anorganik lebih tinggi dibandingkan dengan kandungan hara di pupuk organik. Tinggi rendahnya suhu tanah akan berpengaruh pada pertumbuhan tanaman, semakin tinggi suhu tanah maka akan semakin cepat pertumbuhan pada tanaman. Penelitiaan ini bertujuan untuk menganalisis hasil perkembangan tanaman kangkung yang ditanam dengan menggunakan pupuk organik cair COSIWA dan pupuk anorganik cair NPK. Desain penelitian ini adalah pengukuran suhu tanah dan juga ketinggian tanaman berdasarkan kedalaman tanah pada tanah berpupuk organik menggunakan COSIWA dan pupuk anorganik menggunakan NPK cair.

Practical Online Condition Monitoring of DC-Link Capacitors in Modular Multilevel Converters: A Comparative Approach
Authors: Asoodar Mohsen , Nahalparvari Mehrdad , Danielsson Christer , Nee Hans-Peter
Published: January 2024

This article presents a novel scheme for condition monitoring of dc-link
capacitors in modular multilevel converters (MMCs). The proposed
solution uses estimated capacitance values of the dc-link capacitors for
indicating their state-of-health (SoH). Moreover, a comparative approach
is proposed where the estimated capacitance of all submodule capacitors
are used to separate parameter drifts caused by aging from parameter
drifts caused by other factors such as temperature change. It is shown
in simulation and experimental results that a short-term equal drift in
all capacitance estimates can be a result of factors other than aging.
However, a drift in the capacitance of one capacitor compared to the
average capacitance of all submodules may be attributed to aging of that
specific unit. Using the proposed comparative technique, there is no
need for additional temperature sensors to incorporate the effect of
temperature variations on the online estimations. Simulation and
experimental results prove an overall estimation error of less than 1%
when applying the proposed comparative technique.
Unconventional Security for the IoT: Hardware and Software Implementation of a Digital Chaotic Encrypted Communication Scheme
Authors: Karagiorgos Nikolaos F , Stavrinides Stavros G , Benito Carol de , Nikolaidis Spyridon , Picos Rodrigo
Published: January 2024

The two main issues in the area of the Internet of Things are low resources consumption and secure data transmission. Conjugating both is fairly hard on ensuring security, leading to great efforts in research. The standard cryptography methods currently proposed are based on simplifications of standard protocols, but are still demanding on resources. Chaotic encryption is a way to reduce this burden, while keeping an equivalent level of security. In this paper, we propose, for the first time, a purely digital scheme for chaotic secure communications, able to be implemented in hardware or software without occupying most of the available resources. Next to the delivered analysis of the system, the experimental demonstration on both FPGA and ESP32 Arduino platforms of chaotic synchronization between transmitter and receiver, included examples of applied encrypted communication in the case of consecutive picture and text transmissions.
Automated Machine Learning: Evaluation without Training
Authors: Garg Manav S.
Published: January 2024

Recent studies in deep learning and neural networks have resulted in a
significant breakthrough on several forefronts. Despite their success,
the time and expertise required to build a neural network is immense.
This led to the development of Automated Machine Learning (AutoML) which
is a process to automate aspects of the machine learning pipeline.
Neural Architecture Search (NAS) algorithm, a subset of AutoML focusing
on architecture engineering, tends to be slow to train and is a
computationally expensive process requiring a vast number of candidate
networks which potentially limits their development. A solution to this
problem would be to explore evaluation metrics that would allow us to
get an estimation of a model’s performance while utilizing fewer
computational resources. This paper is a compilation of all the recent
developments in multiple sub-fields of AutoML, following which our
discussion focuses on evaluation strategies that can provide intrinsic
feedback about a proposed architecture without any traditional training
while being computationally inexpensive. This will allow us to
differentiate between good and bad performing architectures at
initialization. We discuss the strategies employed by the current
state-of-the-art, and their limitations, as we then propose multiple
methods for running AutoML processes without training.
Analysis of the Impact of the Increasing Inverter-based Resources on Inter-area Modes of the U.S. Eastern Interconnection
Authors: Agrawal Urmila , Huang Renke , Fan Xiaoyuan , Huang Zhenyu
Published: January 2024

The retirement of conventional synchronous generators and the
integration of inverter-based renewable energy sources (RES) are
transforming power systems in unprecedented ways. Understanding the
impact and consequences of this resource mix transition is crucial to
maintaining reliable grid operation. In this regard, this paper examines
the impact of increased renewable energy sources on the oscillatory
behavior of the U.S. Eastern Interconnection. From our analysis, we
found that no single trend could be used to correlate the impact of
increased RES penetration levels on the damping ratio of system modes.
In fact, the impact of the increased RES penetration levels on a system
mode was influenced by the group of synchronous machine models that were
replaced with RES machine models. For example, replacing the synchronous
generators in Florida significantly increased the damping ratio of the
0.21 Hz mode, whereas the impact was relatively small on the mode when
synchronous machines were replaced in the North-eastern areas of the EI.

Published: January 2024

Background: Hydatid disease is a zoonotic condition caused by the adult or the larval form of Echinococcus granulosus or less commonly Echinococcus multilocularis. The clinical presentation depends on the site of involvement. Many cases are not symptomatic and may be discovered accidentally. Hydatid cyst of the ovary is an extremely rare presentation that accounts for 0.2–1% of the diagnosed cases. It may be mistaken for ovarian cysts or cystic tumors of the ovary. The diagnosis is often based on the couple ultrasound-hydatid serology, but only the histopathological study can confirm the diagnosis of ovary hydatid cyst. Case report: A 40-years-old woman (G4P4), consulting for lower abdominal pain and frequent urination for the last 3 months. The clinical examination was normal besides a discrete pain in the supra-pubic region. Ultrasound of the abdomen showed evidence of cystic mass on the left ovary. A computerized tomography scan of the abdomen revealed the same lesion with no enhancement after contrast injection. In laparotomy we found a latero-uterine cystic lesion measuring approximately 6,5x3,5x4,7 cm there was evidence of a hydatid cyst of the left ovary. The treatment consisted on aspiration with injection of chlorhexidine. The patient underwent a hysterectomy with salpingo-oophorectomy with simple postoperative course. The diagnosis of hydatid cyst was confirmed through histopathological examination. Conclusion: The diagnosis of hydatic ovarian cyst is often based on the couple ultrasound-hydatid serology, but only the histopathological study can confirm the diagnosis The surgical treatment depends on the volume and location of the cysts. Hysterectomy remains the treatment of choice to avoid recurrences. Medical treatment is only necessary when the excision is incomplete or for multiple locations.

The security crisis experienced by our country in 2012 resulted in numerous injuries and deaths linked to terrorist attacks and this required a reorganization of the care of the injured. The objective of this work was to describe the clinical aspects of war injuries at the Sominé Dolo hospital in Mopti (Mali). We we realized a single-center descriptive cross-sectional study relating to the files of patients suffering from war injuries and admitted to the emergency reception department of the Sominé Dolo hospital in Mopti (Mali) during the period between January 1, 2020 and October 31, 2022. This hospital represents the largest reference structure in central Mali with per year. The frequency of war injuries was 2.34%. The average time to admission of our patients before 24 hours was 80% and after 24 hours it was 10%. The injured who received pre-hospital care represented 95.13%. Each patient had an average of 2.25 lesion locations. In 79% of cases, it was a gunshot wound and in 15% of cases it was an injury from improvised explosive devices. The sites of the lesions were: the upper limbs (50.90%), the lower limbs (45%), the cephalic region (14.60%), the abdomen (11.80%), the thorax (6%), the spine (7.10%). The mortality rate was 0.39% in the emergency room.

Cubital tunnel syndrome is the second most common compressive neuropathy in the upper extremity after carpal tunnel syndrome. Severe cubital tunnel syndrome is confirmed by axonal loss in electromyography and conduction velocity less than 40 meters/second in the nerve conduction study. As the severity of compressive neuropathy of the ulnar nerve increases, the results of surgical treatment worsen. Axonal regeneration progresses at a rate of 1 to 3 millimeters per day; However, the muscle is irreversibly denervated after 12 to 18 months. Due to the great distance between the location of the compression, the elbow, and the intrinsic muscles of the hand, reinnervation race against time so that irreversible degeneration of the motor plate and subsequent muscle atrophy does not occur. The supercharged end-to-side transfer of the anterior interosseous nerve to the motor fascicle of the ulnar nerve, to treat severe compressive neuropathies, allows earlier neuroregeneration of the intrinsic muscles of the hand, maintaining the viability of the motor plate, while the affected ulnar nerve regenerates throughout its journey.

Snoring is a loud buzzing noise caused by the soft palate and pillar vibration. Loud snoring at least three nights per week is described as habitual snoring (HS). Aim of the Study: To evaluate the effect of palatal botulinum toxin in snoring patients. Patients and Methods: An Experimental clinical trial study was conducted on thirty-seven patients with habitual snoring between July 2021 and January 2022. The participants and their partners completed a questionnaire submitted before and after injection. Recordings of snoring sounds before injection (as a baseline) and after injection were monitored by a mobile application designed to record and analyze snoring (Goodsomia Lab.). Unilateral injections of 10 botulinum toxin type A units were done into the soft palate muscles. Result: Snoring was improved in all patients, with no significant side effects reported. Epworth Sleepiness Scale was 9.9 ± 0.9 before botulinum toxin injection and 8.2 ± 1.7 one week after injection, while the snoring index was 131 ± 66 and 61.5 ± 28, respectively. The average Intensity of Snoring and maximal Intensity of Snoring before botulinum injection were 57 ± 7.5 and 90.5 ± 1.6, respectively, and changed to 44 ± 4.2 and 87.8 ± 1.9 seven days after injection. Regarding the lowest pulse oxygen saturation, there is a statistically better rate after toxin injection, 90.7 ± 0.9, than before injection, 89.1 ± 1.8. Discussion: Snoring treatment with botulinum toxin is safe, easy to perform, non-invasive, and reversible.

Background: Breast cancer is currently the second leading cause of cancer deaths in women. Early detection and accurate classification of suspicious masses as benign or malignant is important for arriving at an appropriate treatment plan. Aims: To evaluate the resection margin by intra-operative frozen section in breast conserving surgery for early breast carcinoma. Methods: This cross sectional study was carried out in the department of general surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. A total of 20 patients with early stage breast carcinoma underwent surgery were included in this study. Admitted patients with diagnosis of invasive ductal carcinoma of the breast, patient who gave consent for research purpose, patients diagnosed with stage I & II breast cancer, small (up to 4 cm) unifocal tumor and clinically negative axillary nodes were enrolled in this study. Statistical analyses of the results were obtained by using window based computer software devised with Statistical Packages for Social Sciences (SPSS-22). Results: It was observed that more than one third (40.0%) patients belonged to age 41-50 years. The mean age was 45.55±10.94 years with ranged from 28 to 75 years. Half (50.0%) patient’s educational level was primary. Majority (85.0%) patient’s occupational statuses were housewife. Majority (90.0%) patients had lump size >2-≤5 cm. The mean lump size was 2.89±0.66 cm with ranged from 1.5 to 4 cm. Three fourth (75.0%) patients had lump in the right breast. Almost two third (60.0%) patients had lump in the upper outer quadrant of breast. Two (10.0%) patients had Grade I and 18(90.0%) had Grade II tumor. Three fourth (75.0%) patients had resected tumor of T2 >2-≤5 cm size. The mean size of resected toumour was 2.65±0.62 cm with ranged from 1.4 to 3.8 cm. The frequency of positive resection margin on frozen section was 3 (15%). Among them 1 (33.3%) patient had positive superior margin and 2 (66.7%) had positive lateral ....

Breast cancer remains a significant public health concern, with staging at diagnosis being a critical factor in prognosis and treatment planning. While biomedical markers have been extensively studied, there is a growing interest in understanding the diagnostic impact of various factors on the staging of breast cancer. This cross-sectional study was conducted on 50 patients with diagnosed breast cancer, further stratifying them by stage (I-IV) and correlating with different factors which includes socio demographic factors too. A significant association was found between the less than <12 years of age of menarche (p-value 0.038), more than one children (p value 0.014) and no breast feeding history (p-value 0.05) with advanced cancer stage (stage IV). No significant association was observed among age of menopause, marital status with cancer staging. Among the clinical features of respondents, the size of the breast lump, presence of nipple retraction, and axillary lymph node enlargement were found more with stage IV. The findings suggested that while certain social factors like marital status may not directly influence the stage at diagnosis, the number of children a patient has could be an indicator of later-stage diagnosis. About 40% of respondents were diagnosed at stage IV, followed by 28% at stage III, indicating a trend towards late diagnosis. This may reflect broader societal and behavioural patterns that affect health-seeking behaviour and access to healthcare. The staging of breast cancer based on these clinical features not only guides the therapeutic approach, including the decision for surgery, chemotherapy, and radiation therapy, but also has implications for the patient's survival outcomes. Understanding these associations aids clinicians in developing personalized treatment plans and also plays a role in the development of screening guidelines aimed at early detection.

The competency-based medical education (CBME) approach has introduced medical curricula across the globe, designed to provide flexibility, Responsibility and learner-centredness for medical learners. While traditional surgical skills training in most places has relied on "see one, do one, teach one model", simulation model-based training has been shown to improve surgical interns skills. Safely performing local and regional flaps is often a challenge for surgical residents. Therefore, the aim of this study was to assess the difficulty classification of flaps and establish equivalence between them at each level. A questionnaire and an assessment of surgical skills were sent to all plastic surgery residents and young specialists in Morocco analyzing the theoretical and procedural knowledge of flaps. Skills are assessed using a modified version of an objective structured assessment of the Technical Skills Score.
