The combination of finite element analysis (FEM) and compositional fluid dynamics (CFD), known as FSI, is widely regarded as the most advanced tool available for analyzing pressures and stresses within an aneurysm. However, it is also recognized as being both costly and time-consuming. In general, the accuracy of the solutions obtained using this method is heavily reliant on the quantity and quality of the grid elements employed. An important reason of performing this analysis is to investigate the controversial recommendations of adding blood flow inside the deformable models – which increases the cost and the time of the analysis – against using uniform pressure avoiding the complexity of blood flow analysis. Or using the blood flow analysis in a non-deformable aneurysm shape. The pressure acting on the inner wall is the major determinant of the wall stresses and it leads to wall deformation which will normally affect flow behavior. It is debated that pressure variations, due to fluid motion, can significantly affect wall stress results. And it is also debated that deformation of the aneurysm wall due to acting pressure can affect the blood flow behavior and lead to more or less pressure distribution on the wall. These controversial conclusions made the role of blood flow and FSI in varying the blood pressure in the aneurysm internal wall unclear and hence more investigations are required.","PeriodicalId":92231,"journal":{"name":"Journal of biomedical engineering and medical imaging","volume":"69 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135724717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clinical case: A 41-year-old male patient without comorbidities underwent laparoscopic cholecystectomy, during which bile leak from the accessory duct was detected. Double ligation was performed. During the postsurgical period, the patient presented a good clinical evolution. No evidence of collections, fistulas or any complications. Discussion: Different case series demonstrate that injuries during laparoscopic cholecystectomy are usually recognized during the procedure or more commonly in the immediate postoperative period. In the immediate postoperative period, the presence of bile output through a drain or peritoneal signs should imply a biliary injury. Localized accumulation of bile can produce a sterile bilioma , subhepatic or interhepatophrenic abscess . Conclusions: Surveillance must be exercised before any cholecystectomy, whether open or laparoscopic, since the presence of bile leak, its clinical presentation, diagnosis, classification, complexity and adequate treatment can reduce morbidity and mortality in the patient.","PeriodicalId":92231,"journal":{"name":"Journal of biomedical engineering and medical imaging","volume":"70 4‐5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135724713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, women are unique among the 4,300 mammal species suffer from a harmful complication of pregnancy, preeclampsia (especially during a first pregnancy). This paper explains first, concerning physiological vaginal first birth (primiparity) why young women should consider delivering her first baby before the age of 26 (there is a linear association between maternal ages and healthy deliveries). Second, because of the comparatively large human fetal brain, nutritional maternal-foetal exchanges are twice those of other mammals (per body-mass ratios). But, as the human species has retained the hemochorial placenta, that first appeared in mammalian evolution, women face the great challenge of immunological tolerance towards the male partner’s tissues during the nine months of gestation. This major challenge occurs during the first pregnancy and tolerance is related to semen exposure prior to conception.  In subsequent additional pregnancies, immunological recognition is largely achieved through the initial pregnancy. This is why for a first pregnancy (nulliparous woman or multiparous woman with a new male partner), it is preferable to conceive after a delay of 6 months of non-barrier contraception before planning conception. In case of short sexual cohabitation since the constitution of the couple (partial recognition of the male’s tissue), implantation of the embryo may be partially insufficient, leading to complications such as fetal growth restriction and/or early onset preeclampsia. Third, to have a baby neither too small, nor too big, women overweight or obese at the beginning of any pregnancy must gain less weight during the 9 months of gestation as compared to their leaner counterparts. The optimal gestational weight gain may be acknowledged during the first prenatal visit, with, a goal to achieve during the next 7- 8 months of pregnancy.","PeriodicalId":92231,"journal":{"name":"Journal of biomedical engineering and medical imaging","volume":"66 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135724581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In general, LGS often occurs in young children. The etiology of LGS can be classified as cryptogenic or symptomatic. Symptomatic etiology of LGS can be secondary to hypoxic ischemic encephalopathy, congenital brain malformation, vascular malformation, genetics (tuberous sclerosis), trauma, brain tumor, or perinatal meningoencephalitis. Clinical Case: This is a 29-year-old woman, who has a significant history of prolonged prostration; severe cognitive disorder, Lennox-Gastaut syndrome since childhood. She was admitted to the emergency department with symptoms of abdominal distension of seven days of evolution and generalized pain in all abdominal quadrants. A simple computed tomography of the abdomen was performed, where distension of bowel loops was observed at the expense of mesenteric torsion with data of colonic volvulus with little free fluid. It is evaluated by the general surgery service who determines emergency surgical management by means of exploratory laparotomy, the following findings are addressed and obtained: toxic megacolon from the left end of the transverse colon to the middle third of the sigmoid colon, with multiple necrotic patches, as well as volvulus of the transverse and sigmoid colon, proceeding to perform a left hemicolectomy with colostomy of the transverse colon. Discussion: In children, the incidence is estimated at 2 per 100,000, and it is common in men. LGS is one of the most commonly encountered drug-resistant epileptic encephalopathies, with mortality rates ranging from 3-7%. There are many treatment options for these patients, such as antiepileptic drugs, ketogenic diets, VNS therapy (vagus nerve stimulation) callosotomy, and resective epilepsy surgery.","PeriodicalId":92231,"journal":{"name":"Journal of biomedical engineering and medical imaging","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135766628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adult women and seniors are most affected and are commonly associated with urinary tract obstruction and infection. Children are rarely affected, as well as bilateral impairment. Clinical Case: A 54-year-old female comes to the emergency room with right lower back pain, nausea, vomiting, and fever. She denies chronic degenerative diseases and refers to herself as a carrier of right renal lithiasis. Surgical History: open cholecystectomy 20 years ago, two cesarean sections 33 and 23 years ago. The current condition began two months ago with pain in the right lumbar region, accompanied by intermittent fever during the day, presenting partial improvement with analgesics and antipyretics. In the last 24 hours, he presented vomiting of gastro biliary content on four occasions and increased lumbar pain. Upon admission, we performed abdominopelvic tomography, in which an enlarged right kidney was observed, with extensive loss of morphology with ectasia throughout the collecting system that extends to the UP junction with the presence of a 20x20 mm stone with a density of 800 HU inside, ureter with slight ectasia along its entire length, identifying the bear claw sign. Due to tomographic findings with obstructive uropathy and in the presence of data of systemic inflammatory response, he decided to perform diversion of the urinary tract with a double J ureteral catheter without success despite several attempts. Discussion: The precise pathophysiology remains incompletely understood. However, given the observed associations, the combination of obstruction and infection is presumed to be the primary initiators, resulting in interstitial pyelonephritis and a subsequent chronic granulomatous immune response that fails to eradicate the inciting agent.","PeriodicalId":92231,"journal":{"name":"Journal of biomedical engineering and medical imaging","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135766266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: the objective of this study was to investigate worker’s experiences on childbirth complications and the risk factors that affects pregnant women who visit health facilities. The research's driving questions were, \"What are the most frequent problems during childbirth in Mogadishu, Somalia?\" What do medical professionals anticipate as the potential Risk factors of delivery complications? Materials and Methods: The study's cross-sectional assessment of health worker’s experiences on childbirth complications and their risk factors were planned to be gathered from data at a specified group of healthcare facilities in Mogadishu, Somalia, The study's target population consisted of 78 health workers who were asked to respond to childbirth complications; 65 participants were chosen using non-probability methods. The questionnaires were used, and then analyzed in excel and SPSS into frequency table and descriptive statistics (Mean and standard deviations). Results: The significance of discovering the highest percentage that was a Health worker’s experiences on childbirth complication in Mogadishu, Somalia, including \"labor that does not progress (prolonged labor),\" which is 67.7% of respondents who strongly agreed and agreed the existence of this complication at the Mogadishu maternal health center.
