Abstract
The concept of 'Hallmarks of Cancer' is an approach of reducing the enormous complexity of cancer to a set of guiding principles. As the underlying mechanism of cancer are portrayed, we find that we gain insight and additional aspects of the disease arise. The understanding of the tumor microenvironment (TME) brought a new dimension and led to the discovery of novel hallmarks such as senescent cells, non-mutational epigenetic reprogramming, polymorphic microbiomes and unlocked phenotypic plasticity. Circular RNAs (circRNAs) are single-stranded, covalently closed RNA molecules that are ubiquitous across all species. Recent studies on the circRNAs have highlighted their crucial function in regulating the formation of human malignancies through a range of biological processes. The primary goal of this review is to clarify the role of circRNAs in the most common form of liver cancer, hepatocellular carcinoma (HCC). This review also addressed the topic of how circRNAs affect HCC hallmarks, including the new generation hallmarks. Finally, the enormous applications that these rapidly expanding ncRNA molecules serve in the functional and molecular development of effective HCC diagnostic biomarkers and therapeutic targets.

Abstract
Atrial myxoma, though the most common primary cardiac tumor, often presents with nonspecific symptoms that can obscure its diagnosis. This case report details an unusual presentation of dyspnea on exertion (DOE) in a patient initially considered to have chronic obstructive pulmonary disease (COPD), a common pulmonary etiology of DOE. The diagnostic journey underscores the critical importance of considering atrial myxoma in patients with DOE, especially when symptoms are not fully explained by apparent pulmonary conditions. Our findings highlight the necessity of a comprehensive diagnostic approach, including the early use of resting transthoracic echocardiogram, to unveil less common causes like atrial myxoma. This case reinforces the pivotal role of considering alternative diagnoses in complex presentations of DOE, thereby guiding more accurate and tailored patient management.

Abstract
Rhabdomyosarcoma (RMS) is a highly sporadic, very aggressive, and fatal soft tissue tumor in adults. Although more common and treatable in the pediatric population, the occurrence of pleomorphic RMS in adults has a low incidence. Hence, it is not easy to treat. Surgery is the primary definitive treatment, along with radiation therapy, while adjuvant chemotherapy has recently gained popularity. We present an infrequent case of RMS in a patient with a recent history of mixed non-seminomatous germ-cell tumor testicular cancer. Therefore, it was challenging to treat the RMS as a new malignancy or as a recurrence of non-seminomatous testicular cancer. Our patient passed away, unfortunately, but we hope this case can help the minimal data in this regard in order to save more lives in the future.

Abstract
The lung's sarcomatoid carcinomas (SC) are a heterogeneous sporadic group of non-small cell lung carcinomas (NSCLCs) and are very challenging to diagnose and treat. Spindle cell carcinoma (SpCC) is a very rare subset of this group. Hence, the prognosis and treatments are unclear due to the limited literature available. The presentation of this cancer varies based on the site of the neoplasm and the complications and metastases observed at the time of diagnosis. Here, we report a 73-year-old man who presented to the emergency room after two months of worsening dyspnea and fatigue. Chest X-ray showed an extensive left-sided pleural effusion. A computed tomography (CT) scan of the chest showed a pleural-based mass that came back as SpCC, for which he was referred to a university hospital.

Abstract
Hepatocellular carcinoma (HCC) is a very aggressive type of cancer and can either invade or spread distantly through the portal vein to the inferior vena cava (IVC) and the right atrium (RA). The presentation varies based on the stage of the cancer at the time of diagnosis. Liver transplantation or surgical resection is the ideal management of small lesions without metastases, while systemic therapy can help in extensive cases to decrease the tumor burden to allow surgical resection of the tumor. We present a rare case of HCC with a tumor thrombus (TT) extending to the RA. Unfortunately, the patient did not survive the cancer. We hope that this case report can contribute to saving the lives of future patients with HCC.

Abstract
Pyoderma gangrenosum (PG) is an autoinflammatory skin disease, and there is no definitive test or established criterion for its diagnosis yet. This report discusses a case of a 34-year-old male patient who presented with an unassuming lesion that quickly worsened with physical manipulation. He was eventually diagnosed with PG. This report highlights the importance of a quick and accurate diagnosis of PG to prevent the worsening of a PG wound and its associated morbidity. It provides a detailed description of the condition accompanied by images to further spread awareness of this rare diagnosis.

Abstract
Familial Mediterranean fever (FMF) is a hereditary disorder characterized by episodes of fever, polyserositis, or cutaneous inflammation. The FMF attacks last 1-3 days and have no apparent triggers. Recurrent deposition of the serum amyloid A (SAA) protein in the gut can cause intractable diarrhea, dysmotility, and recurrent abdominal pain. Gastrointestinal amyloidosis is a rare, but serious, complication of FMF. In this case report, we describe a rare case of chronic diarrhea and recurrent abdominal pain due to FMF-induced gastrointestinal amyloidosis.

Abstract
Sinistral portal hypertension (SPH), also known as segmental portal hypertension, is a complication of pancreatic disorders and an extremely rare cause of upper gastrointestinal (GI) bleeding. SPH is observed in patients without cirrhosis and arises from splenic vein thrombosis. Unmitigated backflow of blood may cause gastric venous congestion and ultimately GI hemorrhage. Herein, we report a rare case of massive hematemesis due to SPH in a male patient with a history of chronic pancreatitis and pancreatic pseudocyst. Our patient was successfully treated with endoscopic necrosectomy followed by open splenectomy, distal pancreatectomy, and partial gastric resection.

Abstract
Subdural empyema is a collection of pus in the subdural space between the dura mater and the arachnoid. It carries very high morbidity and mortality as it can spread anywhere in the brain; however, the risk can be mitigated with appropriate surgical and medical intervention. Being protected by the skull, cranial infections are usually preceded by a significant risk factor, either an external invader such as skull fractures secondary to trauma, penetrating injury, prior surgery, or, more commonly, in more than 50% of cases, due to spread of an internal infection such as ear or sinus infections. Anaerobic and aerobic bacteria can cause subdural empyema. Both gram-positive and gram-negative bacteria are notorious for developing this kind of infection; for example, different groups of gram-positive streptococci and staphylococci, gram-negative Haemophilus influenza, and other gram-negative bacilli can cause subdural empyema. While streptococci are more frequent with sinus infection causing subdural empyema, staphylococci are associated with skin invasion secondary to either head trauma or cranial surgery. Streptococcus intermedius is a gram-positive alpha-hemolytic pathogen belonging to the larger Streptococcus anginosus group that itself is a subgroup from viridans streptococci, aka Streptococcus milleri. Streptococcus intermedius is an oral commensal flora and is considered to be a low-virulence bacteria in immunocompetent patients but can be associated with significant morbidity and mortality. Subdural empyema tends to occur more often in immunocompromised patients such as diabetic patients, those with human immunodeficiency virus infection, and those using immunosuppressive medications. The clinical course ranges from indolent to fulminant. The size and location of the abscess play a role in clinical presentation. Headache is the most common presenting symptom, but patients can also present with fever, nausea, seizure, or altered mental status. Diagnosis can be obtained with CT and MRI scans of the brain. Prompt drainage of the abscess and lengthy antibiotics improve the prognosis significantly. Our case highlights a rare origin of subdural empyema from the direct spread of a skin abscess.

Abstract
Thrombocytopenia with concomitant anemia is a serious condition with a high mortality risk. Destruction of platelets, i.e., thrombocytopenia, can be secondary to either auto-antibodies (immune-mediated) or mechanical destruction (non-immune-mediated). The Coombs test is a widespread tool to differentiate between the two categories, resulting in different specific treatment approaches for each diagnosis. A peripheral blood smear can also help make the diagnosis; for instance, in cases of mechanical destruction such as thrombotic thrombocytopenic purpura (TTP), the red blood cell (RBC) shape looks fragmented, forming schistocytes. In rare instances, TTP can present with both schistocytes and a positive Coombs test, challenging the diagnosis of TTP. TTP is a hematological emergency requiring appropriate anticipation and the initiation of treatment prior to the confirmatory ADAMTS-13 test results. Mild forms of TTP can be managed with glucocorticoids and therapeutic plasma exchange. Refractory cases need more aggressive additional treatment with caplacizumab and rituximab. Caplacizumab is an expensive medication that is usually reserved for use after confirmation of a TTP diagnosis. The advantage of caplacizumab lies in its targeted mechanism of action against the A1 domain of the von Willebrand multimers that are normally destructed by the ADAMTS-13 enzyme. Here, we present a young female patient with confirmed TTP, and the initial diagnosis was challenged by the presence of antibodies with the Coombs test. Very little research has studied this rare instance and the appropriate treatment. Our case will save many future lives, as clinicians should be more aggressive in treating refractory TTP with a positive Coombs test.

Abstract
An abscess is a collection of pus secondary to an immune response to a pathogen. It can occur anywhere in the body, with the skin as the most common organ involved. A lip abscess is a rare condition. Generally, it may be due to an infective agent such as a virus or bacteria entering through a skin wound, or through hematogenous spread when there is a severe underlying condition such as a general condition disorder or immunodeficiency. It requires hypervigilance during the examination and throughout the treatment course with intravenous antibiotic therapy and urgent surgical drainage, as it may cause significant complications regarding localization, lymphovascular drainage, and ultimate spread. Persistent abscess, necrotic tissue, or cavitated lesions are worrisome and it is important to rule out immunosuppression or a methicillin-resistant staphylococcus. In this case, a 22-year-old male patient with a unilateral lip abscess, misdiagnosed as an allergic food reaction, responded well to external drainage and antibiotic therapy.

Abstract
We present the case of an 88-year-old man with a previous medical history of severe colitis and colonic strictures who presented with hematemesis. The patient was found to have a lower esophageal ulcer without any signs of perforation. Esophagogastroduodenoscopy (EGD) revealed a scar in the greater curvature of the stomach from a previously removed gastrostomy tube two months prior. On CT imaging, an incidental finding of pneumoperitoneum was also found alongside stomach perforation near the healing scar. Due to the lack of evidence of any other colonic perforation, the patient was believed to have developed this pneumoperitoneum status post-gastrectomy tube removal two months prior to presentation. Pneumoperitoneum has a wide range of presenting symptoms that vary in severity and nature, and our patient failed to present with any physical or laboratory signs of infection. Over the course of the next four months, the patient was monitored with serial CT scans, during which the pneumoperitoneum resolved. In this report, we present a case of a patient who was found to develop pneumoperitoneum post-gastric tube removal and its complete resolution without surgical or procedural intervention.

Abstract
INTRODUCTION Research into patient and public views on predictive software and its use in healthcare is relatively new. This study aimed to understand older adults' acceptability of an opportunistic bone density assessment for osteoporosis diagnosis (IBEX BH), views on its integration into healthcare, and views on predictive software and AI in healthcare. METHODS Focus groups were conducted with participants aged over 50 years, based in South West England. Data were analysed using thematic analysis. Analysis was informed by the theoretical framework of acceptability. RESULTS Two focus groups were undertaken with a total of 14 participants. Overall, the participants were generally positive about the IBEX BH software, and predictive software's in general stating 'it sounds like a brilliant idea'. Although participants did not understand the intricacies of the software, they did not feel they needed to. Concerns about IBEX BH focussed more on the clinical indications of the software (e.g. more scans or medications), with participants expressing less trust in results if they indicated medication. Questions were also raised about how and who would receive the results of this software. Individual choice was evident in these discussions, however most indicated the preferences for spoken communication 'But I would expect that these results would be given by a human to another human.' CONCLUSIONS Focus group participants were generally accepting of the use of predictive software in healthcare. IMPLICATIONS FOR PRACTICE Thought and care needs to be taken when integrating predictive software into practice. Focusses on empowering patients, providing information on processes and results are key.

Abstract
Laryngeal cancer is predominantly a squamous cell in origin that can present with voice changes and difficulty or pain with swallowing. It is more likely to cause local spread than distant ones. The prognosis depends on multiple factors, including the stage, tumor differentiation, extranodal extension, and adjuvant therapy. Head and neck cancers have a higher tendency for perineural invasion and spread, one of the most vital factors correlating with poor outcomes and recurrence rates. We present a rare case of a 52-year-old male with an extensive history of tobacco use (five packs per day over 30 years) who developed laryngeal squamous cell carcinoma that spread to the brain despite total laryngectomy and adjuvant radiation therapy. Despite resection of the brain metastasis, the tumor metastasized again in the brain through perineural spread. Due to the side effects of repeated radiotherapy and starting chemotherapy, the patient opted for comfort care and refused further treatment. The perineural spread of head and neck cancers is not abundant in the literature, and we believe our case will add to the future treatment of head and neck cancers with perineural invasion.

Abstract
Malignant pericardial effusion (MPE) is a slowly progressive and potentially clinically silent condition. Pericardial effusion can arise in oncology patients due to several factors, including disease spreading directly or metastatically, anticancer therapy side effects, or both. Solid and hematological malignancy metastasis more frequently involves the pericardium than primary tumors, with lung cancer being the most common metastatic tumor to involve the pericardium. While 5%-20% of all patients with metastatic neoplasms have pericardial involvement, MPE rarely appears with hemodynamic instability. Occasionally, MPE constitutes the initial manifestation of an underlying malignancy. Diagnosis and treatment require a multidisciplinary approach and a high degree of clinical suspicion. We present a case of a 59-year-old female with a history of peritoneal carcinoma who presented with persistent dyspnea on exertion following an episode of pneumonia that was treated with antibiotics. Physical examination and bedside point-of-care ultrasound (POCUS) revealed fluid in the pericardial sac. The cytological examination of the fluid revealed it to be of malignant origin, resulting from metastasis from gynecologic adenocarcinoma. Pericardiocentesis was done, and symptoms improved after fluid drainage.

Abstract
Kidney stone formation is an intricate process that involves a disruption in the interplay of the multiple organs and systems involved in regulating the concentration of specific ions in the body. Women who have gone through menopause are susceptible to kidney stone disease. This systematic review aims to investigate the potential influence of estrogen on kidney function and oxalate homeostasis, notably through the anion transporter SLC26A6 (also known as putative anion transporter 1 or PAT1) in females. In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 checklist, a systematic search of online databases included Pubmed, ScienceDirect Journals, and Ingenta Connect Journals. Predetermined criteria to include and exclude papers, gathering articles published between 2012 and 2022, were determined. After a thorough analysis, eight articles (three cohorts, one case-control, one in vivo, one in vitro, and two cross-sectional studies) were identified for the final quality assessment review. The eight selected and quality-assessed articles provided evidence of a directly proportional connection between estrogen and kidney function. A correlation between serum estrogen levels and the development of kidney stone disease was confirmed. Administration of β-estradiol was shown to effectively inhibit the function of the anion transporter PAT1 in a tissue-specific manner. In the case of the kidney, estrogen was observed to down-regulate PAT1, which led to a reduction in oxalate transporting activity and, consequently, a decrease in kidney stone formation. Consensus suggests that serum estrogen levels and optimal kidney functioning are interrelated. Furthermore, analysis of the quality-assessed articles and a comprehensive literature review revealed estrogen's tissue-specific regulation of the PAT1 anion transporter aids in maintaining kidney function and anion homeostasis. Additional research is needed to solidify estrogen's role in kidney stone disease to determine its therapeutic value in clinical practice.

Abstract
Achalasia, a neurodegenerative disease caused by the progressive destruction of ganglion cells in the myenteric plexus, is accompanied by incomplete relaxation of the lower esophageal sphincter. Laparoscopic Heller's myotomy (LHM) coupled with fundoplication has been the gold standard procedure for achalasia. Peroral esophageal myotomy (POEM) has recently gained popularity as it is minimally invasive, has fewer adverse events, and has excellent short-term outcomes. So, we aimed to compare the clinical efficacy, safety, and postoperative outcomes between LHM and POEM. We did a systematic review by following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines for 2020 and exploring research databases such as PUBMED and PMC Central, Google Scholar, and Research Gate. After appropriate screenings, articles relevant to the review were scrutinized based on the eligibility criteria. Quality assessment tools such as the Newcastle-Ottawa Scale (NOS) and the assessment of multiple systematic reviews (AMSTAR) were used to finalize the articles. A total of 11 articles (seven observational studies, two RCTs, and two systematic reviews) were included in the review after a quality check. The study included 2127 patients, classified into 981 for POEM and 1146 for LHM, who had undergone treatment for achalasia. Most of the studies had a follow-up of ≤ two years. Comparing efficacy, POEM had similar results to LHM in terms of Eckardt scores. However, abnormal DeMeester scores were found in POEM. Adverse events were significantly higher in LHM when compared to POEM in terms of safety. Peroral esophageal myotomy also stood out as having a shorter procedure time, a shorter hospital stay, and lesser odds of being a clinical failure. As for postoperative outcomes, despite treatment with proton pump inhibitors, LHM was more effective in preventing the development of esophagitis compared to POEM due to partial fundoplication. Postoperative reflux and the development of esophagitis remain certain with POEM and need to be followed up with more studies with longer follow-ups. However, POEM still stands as a better choice compared to LHM in terms of efficacy and safety.

Abstract
Autoimmune Hepatitis (AIH) is a progressive form of chronic hepatitis, with periods of remissions and exacerbations. Diagnosis includes abnormally high levels of immunoglobulins and multiple autoantibodies. Clinical presentation is variable, with a spectrum extending from asymptomatic cases to fulminant liver failure. Symptoms include abdominal pain, malaise, fatigue, and small joint arthralgia. We present a case of a 36-year-old male with a past medical history of alcohol dependence and acute pancreatitis who was diagnosed with AIH. There is limited data regarding patients with concomitant AIH and pancreatitis. Our patient presented with AIH with secondary acute on chronic pancreatitis, in the absence of additional autoimmune manifestations. The mechanism of AIH remains poorly understood; however, there is an association between the HLA gene and AIH. Genetic studies have shown HLA-DRB1*0301 and HLA-DRB1*0401 as primary and secondary genotypes susceptible to AIH, as well as genetic variants with CARD10 and SH2B3. Products secondary to metabolism of ETOH such as alcohol dehydrogenase, malondialdehyde, and acetaldehyde, can lead to development of autoantibodies. Additional research is indicated to evaluate the relationship between AIH and acute pancreatitis.

Abstract
Metastasis is the principal cause of cancer death, yet we lack an understanding of metastatic cell states, their relationship to primary tumor states, and the mechanisms by which they transition. In a cohort of biospecimen trios from same-patient normal colon, primary and metastatic colorectal cancer, we show that while primary tumors largely adopt LGR5 + intestinal stem-like states, metastases display progressive plasticity. Loss of intestinal cell states is accompanied by reprogramming into a highly conserved fetal progenitor state, followed by non-canonical differentiation into divergent squamous and neuroendocrine-like states, which is exacerbated by chemotherapy and associated with poor patient survival. Using matched patient-derived organoids, we demonstrate that metastatic cancer cells exhibit greater cell-autonomous multilineage differentiation potential in response to microenvironment cues than their intestinal lineage-restricted primary tumor counterparts. We identify PROX1 as a stabilizer of intestinal lineage in the fetal progenitor state, whose downregulation licenses non-canonical reprogramming.

Abstract
Inflammatory bowel diseases (IBDs), including Crohn's disease and ulcerative colitis, are immune-mediated chronic inflammatory diseases that target the gastrointestinal tract and other distant organs. The incidence of IBDs has been rising and is more prevailing in Western communities. The etiology has been vague, but different theories include environmental factors that elicit an uncontrolled immune response, which damages internal organs. Treatment of either Crohn's disease or ulcerative colitis has witnessed significant advances; however, pharmacological drugs' side effects limit their use. Research about microbiota and its influence on IBDs has gained fame, and multiple studies correlate microbiota diversity positively with IBD treatment. Many factors contribute to the microbiota's health, including different diets, antibiotics, prebiotics, probiotics, synbiotics, and postbiotics. Specific immune responses lie behind the pathogenesis of IBDs and microbiota dysbiosis, and different studies have postulated new ways to control this abnormal response. Physical activity, sun exposure, efficient sleep, intermittent fasting, and supplementation of probiotics and vitamins are natural ways that help modulate this immune response, do not cost money as IBD pharmacological drugs, and do not come with deleterious side effects that are sometimes more harmful than IBDs. Our article proposes a comprehensive natural approach that can benefit IBD patients enormously. This approach does not replace the medications currently used in treating IBDs. The suggested approach can be used in combination with medications and might aid in reducing the doses of those medications.

Abstract
The benefits of physical activity during pregnancy or postpartum are auspicious, especially in preventing and treating postpartum depression. This review aimed to examine the relationship between exercise and postpartum depression in terms of prevention and treatment. The goals were to determine if exercise alone is sufficient for this purpose and to attract attention to the kind, intensity, and duration needed to achieve this purpose. A literature review was conducted in PubMed, PubMed Central, MEDLINE, and Cochrane libraries. The search terms were "physical activity," "postpartum depression," "postnatal depression," and "exercise." Physical activity can be a preventative measure and a treatment aid for pregnant or postpartum women with depressive disorders. However, the exercise protocol should include a support/wellness program to achieve better and more remarkable results.

Abstract
Peptic ulcer disease (PUD) refers to the occurrence of an open erosion in the inner lining of the stomach, duodenum, or sometimes lower esophagus. Treatments like proton pump inhibitors (PPIs) or histamine 2 receptor antagonists (H2RAs) are available on the market to efficiently treat the break in the mucosal lining. However, there is little evidence about the effects of the medication on the type and location of the ulcer and the epigastric pain caused by disintegration and increased acidity in the stomach. Given the above, we conducted a systematic review comparing the safety and efficacy of PPIs and H2RAs in various ulcer locations (gastric, duodenal, and pre-pyloric) and the effect of prolonging the treatment with the same medication or changing into a drug from another class in treatment-resistant ulcers. We employed major research literature databases and search engines such as PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), Science Direct, and Google Scholar to find relevant articles. After a thorough screening, a quality check using various tools, and applying filters that suited our eligibility criteria, we identified eight articles, of which five were random clinical trials (RCTs), two review articles, and one meta-analysis. This study compares the different side effects of PPIs and H2RAs. Most studies concluded that omeprazole is superior in healing ulcers and bringing pain relief and that patients resistant to H2RAs can be treated better when switched to a PPI. This study also discusses the adverse effects of chronic use, such as diarrhea, constipation, headaches, and gastrointestinal infections. Patients on long-term PPI therapy are required to take calcium supplements to prevent the risk of fractures in older adults. Regarding long-term outcomes, PPIs remain the mainstay of treatment for peptic ulcer disease, based on the papers we reviewed.

Abstract
Cerebral palsy is a group of disorders affecting individuals already from birth. It enormously impacts an individual's physical and emotional life and can bring many challenges to the individual, caregivers, and families. Therefore, it is crucial to investigate interventions that could improve various symptoms in children with cerebral palsy. Our systematic review intends to assess the effect of different exercise and physical therapy interventions in children with cerebral palsy. We used three databases for our article search: PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), and PubMed Central (PMC). The combined number of papers found in all databases was 65,412. We then applied our inclusion and exclusion criteria, filters, key terms, and Medical Subheadings (MeSH). After applying our quality assessment tools, we included nine papers in our systematic review. The studies included in our review used various interventions to assess for improvement in symptoms in individuals with cerebral palsy. Interventions included stretching and resistance exercises, horse riding, biking, core stability exercises, slackline training, a home exercise program using an online tool, sit-to-stand exercise program, and functional training. Many studies have shown that interventions improved symptoms like balance, coordination, gait, and cardiovascular endurance in cerebral palsy. This review suggests that some of the included interventions have great potential to improve the symptoms of cerebral palsy and, therefore, can be a great addition to existing training and rehabilitation programs. Given that studies included a relatively small number of participants and were conducted over a short time, more research with a more significant number of participants over a longer time is necessary.

Abstract
The gut microbiota has been studied and continues to be a developing area in the pathognomic development of metabolic diseases like diabetes. Treatment with diet changes, the addition of supplements like prebiotics/probiotics, and the impact of fecal microbial transplantation can be correlated to targeting changes in dysbiosis. Understanding the impacts of various anti-hyperglycemic agents such as metformin and the implications of post-bariatric surgery on the gut microbiota diversity has emerged. These areas of study are crucial to understanding the pathognomic aspects of diabetes disease progression at the microbial level of metabolic and inflammatory mechanisms, which may give more insight into focusing on the role of diet prebiotic/probiotic supplements as potential forms of prospective management in diabetes and the development of more agents that target gut microbiota, which harbors low-grade inflammation. Intestinal dysbiosis was consistently observed in the mechanism of gut microbial change in diabetic individuals, contributing to reduced insulin sensitivity and poor glycemic control. This systematic review was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 checklist. We performed a literature search using the PubMed, Google Scholar and Science Direct databases in accordance with the eligibility criteria and ultimately selected 14 articles for final analysis. The Scale for the Assessment of Narrative Review Articles (SANRA) and the PRISMA 2020 checklist were used to assess the quality of selected articles for cross-sectional studies, traditional literature reviews, and systematic reviews, respectively. We collected papers from 2012 to 2022 for this review. We gathered articles from databases, such as this study, which show there is a strong connection between microbiota and diabetes that appears to exist. The objective is to assess and identify any dietary and therapeutic agents that may alter the microbiota and potentially target and modulate insulin sensitivity. This review article will discuss the pathophysiological effects of gut microbiota in diabetes management and the impact of various gut biodiversity therapeutics that can aid in reversing insulin sensitivity.

Abstract
Irritable bowel syndrome (IBS) is a gut-brain disorder involving alterations in intestinal sensitivity and motility. Currently, IBS has no cure, and treatment focuses on the management of symptoms. The diverse, and sometimes contradictory, collections of symptoms reported across the different subtypes of IBS make treatment, as well as diagnosis, difficult for physicians. All subtypes of IBS have one symptom in common: abdominal pain caused by differences in the level of visceral sensitivity. Though current research on this topic is in its infancy, some researchers have proven, through experimental studies, that 5-hydroxytryptamine (serotonin) receptor type 7 (5-HT7) affects both visceral sensitivity and smooth muscle tone in the bowel. Therefore, this review will be discussing the future possibility of alleviating abdominal pain in patients with IBS and related disorders by modulating the 5-HT7 receptor.

Abstract
BACKGROUND Refractory hypokalemia has been rarely demonstrated in patients with acute monocytic leukemia (AMoL). Hypokalemia develops in these patients owing to renal tubular dysfunction, secondary to lysozyme enzymes that are released by monocytes in AMoL. Additionally, renin-like substances are produced from monocytes and can lead to hypokalemia and metabolic alkalosis. There is also an entity called spurious hypokalemia, in which high numbers of metabolically active cells in blood samples increase sodium-potassium ATPase activity, resulting in influx of potassium. Additional research is warranted regarding this specific demographic to create standardized treatment approaches to electrolyte repletion. CASE REPORT In this case report, we demonstrate a rare case of an 82-year-old woman with AMoL, complicated by refractory hypokalemia, who presented with concerns of fatigue. The patient's initial laboratory results were significant for leukocytosis with monocytosis and severe hypokalemia. Refractory hypokalemia was noted, despite administration of aggressive repletions. During her hospitalization, AMoL was diagnosed and an extensive workup was performed to evaluate the underlying cause of hypokalemia. Ultimately, the patient died on day 4 of hospitalization. We describe the correlation between severe refractory hypokalemia and leukocytosis and provide a literature review of multiple etiologies of refractory hypokalemia in patients with AMoL. CONCLUSIONS We evaluated the numerous pathophysiologic mechanisms responsible for refractory hypokalemia in patients with AMoL. Our therapeutic outcomes were limited owing to the patient's early death. It is of high importance to evaluate the underlying cause of hypokalemia in these patients and to treat accordingly with caution.

Abstract
Infective endocarditis (IE) carries high morbidity and mortality. Although minimal in incidence, fungal causes (mostly Candida species) carry the highest mortality among all cases of infective endocarditis. We describe a rare case of a 47-year-old male with a past medical history of cerebral vascular accident (CVA), heart failure with reduced ejection fraction status post (SP) automated implantable cardioverter defibrillator (AICD) placement, paroxysmal atrial fibrillation, coronary artery disease (CAD), infective endocarditis with mitral valve replacement and tricuspid valve replacement, and pulmonary hypertension who presented to the emergency department (ED) with complaints of shortness of breath and weakness for four days. The patient was admitted to the cardiac care unit (CCU) due to persistent hypotension despite being on a continuous milrinone drip at home. The patient was initially started on antimicrobial agents for sepsis most likely secondary to pneumonia. Echocardiographic imaging showed a large vegetation on the tricuspid valve; hence, blood cultures were sent and came back positive for Candida sp. Appropriate antifungals (micafungin) were added to the medication regimen, and the patient was transferred to a tertiary hospital for surgical intervention. Patients with bioprosthetic valve replacement require regular follow-ups as this would allow providers to catch symptoms of developing endocarditis and prevent disease progression. These appointments may also decrease other risk factors for the disease, including but not limited to infected lines.

Abstract
BACKGROUND Hamartomatous polyps represent rare sporadic lesions, characterized by fibrous stroma, vascular infiltration, and dilation of mucous glands. The lesions present in a bimodal fashion in adults as well as children from 1 to 7 years old, and are often diagnosed during endoscopic procedures. Specifically, solitary Peutz-Jeghers represents a type of hamartoma that has similar histologic features to typical Peutz-Jeghers syndrome. Hamartomatous polyps represent disorganized tissue growth and can bear relationships with genetic syndromes classified as hamartomatous polyposis syndromes. A number of these syndromes, such as Peutz-Jeghers and Cowden syndrome, can demonstrate an increased risk of malignancy. A variety of symptoms, or no symptoms at all, can accompany these polyps, such as abdominal discomfort, bowel obstruction, gastrointestinal bleeding, or intussusception in severe cases. Histologically, these polyps appear similar to Peutz-Jeghers syndrome growths; however, they lack extraintestinal manifestations. Given fairly low risk of development into malignancy, patients have a good prognosis if presenting with a solitary hamartomatous polyp. There is limited data regarding screening guidelines for this patient population. CASE REPORT Here, we present a rare case of a 73-year-old woman who had a history of anemia and status post endoscopic evaluation and was diagnosed with a benign hamartomatous polyp (juvenile-like), histologically consistent with tubulovillous adenoma. CONCLUSIONS Differentiating sporadic polyps from syndromic polyps is important, as sporadic polyps have a benign course, while those associated with a syndrome have an increased lifetime malignancy risk.

Abstract
BACKGROUND Acute promyelocytic leukemia (APL) is a rare subtype of acute myeloid leukemia (AML) and is characterized by a genetic translocation affecting the retinoic acid receptor-alpha gene, leading to blockage in the differentiation of granulocytic cells. The accumulation of promyelocytes in bone marrow leads to cytopenias and life-threatening coagulopathies. Definitive diagnosis is made with bone marrow biopsy. Differentiation of APL from other leukemias is important to appropriately treat with all-trans retinoic acid (ATRA) and arsenic trioxide. Patients with HIV are at a higher risk to develop AML. This article identifies how multiple comorbidities and social factors can contribute to difficulties in diagnosing AML. CASE REPORT We present a 67-year-old man with a past medical history of hypertension and substance use disorder who presented with progressive exertional dyspnea and was found to have HIV, chronic hepatitis C, and APL with pancytopenia. His bone marrow biopsy confirmed AML. This was a case of co-existing HIV and aleukemic leukemia. CONCLUSIONS APL can present with pancytopenia, weakness, failure to thrive, or bleeding complications, which can be similar to presentations of those diagnosed with HIV. Diagnosis of APL can be differentiated between hypergranular and hypogranular; our patient demonstrated APL with only 52% blasts, which can make for a challenging diagnosis. Given increased mortality of APL, immediate ATRA therapy is warranted. Aleukemic leukemia is a rare presentation typically accompanied by skin manifestations. Our case highlights the importance of having high clinical suspicion for malignancy in patients with comorbidities that can interfere with the classic presentation of leukemia.

Abstract
Panniculitis is an inflammatory process localized to subcutaneous tissue, with etiologies including infection, malignancy, external insults, enzymatic destructive processes, and inflammatory disorders. The incidence of panniculitis manifesting as necrosis of subcutaneous fat tissue associated with pancreatic diseases is low, which may encompass associated periarthritis with bone necrosis and panniculitis (Pancreatitis, panniculitis and polyarthritis syndrome). Pancreatitis, panniculitis and polyarthritis syndrome is considered to derive from the systemic activity of enzymes within the pancreas, which leads to disturbances within the microcirculatory system, and fat necrosis of medullary bone marrow; however, the exact pathophysiology remains unknown. Here, we present a case of a 53-year-old male with a history of chronic pancreatitis who presented with lower abdominal pain found to have osteolytic pelvic lesions considered to be panniculitis secondary to pancreatitis. Our patient provided an interesting clinical picture given his alcohol use disorder, and lytic lesions which lead the team initially towards a malignant etiology of panniculitis such as myeloma; however, given his negative studies, it was presumed his panniculitis was derived from his chronic pancreatitis. Overall, additional literature is warranted regarding the extensive workup of lytic bone lesions that present in patients who have acute vs chronic pancreatitis.

Abstract
PURPOSE To compare the macular and papillary parameters on optical coherence tomography (OCT) between the amblyopic eye and the healthy eye in subjects with unilateral strabismic or anisometropic amblyopia. PATIENTS AND METHODS This is a cross-sectional and comparative study carried out over two years, from April 1, 2019, to March 31, 2021. We included patients aged over 5years, followed for unilateral amblyopia, free of any neurological and/or ocular pathology. The evaluation of the macular and papillary parameters in the amblyopic and healthy eyes was performed with Swept-Source Optical Coherence Tomography (OCT-SS). The parameters were compared according to age group and type of amblyopia. RESULTS We collected 50 patients, 29 children, and 21 adults, with a mean age of 19.8years. Amblyopia was secondary to anisometropia in 40 patients and strabismus in 10 patients. Analysis of macular tomographic parameters found no significant difference between amblyopic eyes and healthy eyes for mean macular thickness (P=0.86), central macular thickness (P=0.86), or mean macular volume (P=0.54). The mean retinal peripapillary fiber thickness (RNFL) was 107.48μm in the amblyopic eye and 103.8μm in the healthy eye, with a statistically significant difference (P<0.001). This significant thickening of the RNFL in amblyopic eyes was present in adults (P<0.001), children (P<0.001), anisometropic (P<0.001), and strabismic amblyopia (P=0.024). Analysis of the other optic nerve head parameters revealed no significant difference between amblyopic eyes and healthy eyes in terms of optic disc surface area (P=0.89), neuro-retinal annulus surface area (P=0.47), vertical (P=0.98) or horizontal (P=0.74) cup to disc ratio. CONCLUSION Amblyopia is accompanied by thickening of the peripapillary retinal fibers without macular repercussions. However, larger prospective studies are needed to confirm these results.

Abstract
The carotid sinus-arterial baroreflex is essential in maintaining blood pressure (BP) regulation. Afferent baroreflex failure (ABF) can present with labile changes in BP within seconds and can be secondary to neck surgery or radiation. We present here the first case, to our knowledge, of ABF precipitated by thyroidectomy, in a patient with active COVID-19 pneumonia, causing difficult control of severely labile BP in a critical care unit. Contributing factors included her critical illness state with upregulation of IL-6 leading to pituitary-adrenal axis alteration, her thyroidectomy further exacerbating autonomic dysfunction, as well as downregulation of ACE2 via COVID-19 infection. Management was achieved with a combination of midodrine and clonidine catered to specific BP thresholds. Additional research with a multidisciplinary approach is warranted to fully optimize the treatment of ABF in patients with neck surgery and or inflammatory conditions such as COVID-19.

Abstract
Toothpick ingestion is a medical emergency requiring urgent intervention. Swallowed toothpicks can cause intestinal perforation, bleeding, or damage to the surrounding organs. Herein, we describe a unique case of a geriatric patient with a history of peptic ulcer disease who presented to the emergency department for the evaluation of abdominal pain and nausea. Gastric wall thickening concerning for a gastric neoplasm was observed on a computed tomography (CT) scan of the abdomen and pelvis. An esophagogastroduodenoscopy (EGD) revealed an embedded toothpick with a contained gastric perforation, and the foreign body was retrieved with a grasper device. Given the rare presentation, nonspecific symptoms, inability to recall, and often inconclusive imaging, a high index of suspicion is needed for early diagnosis and treatment of toothpick ingestion.

Abstract
Abstract
Aim
This study examines the safety and timing initiating VTE prophylaxis post traumatic splenic injuries (TSI).
Method
Patients with TSI were identified from prospectively maintained Trauma Audit and Research Network (TARN) database from 2015–2020 in a single tertiary trauma centre. Clinical and radio-logical information were collected retrospectively. TSI were graded using American Association for the Surgery of Trauma (AAST) splenic injury scale. Chemical venous thromboprophylaxis initiation were categorised as not given, <48h and >48h following the injury.
Results
In total 102 patient were included out of 136 patients identified with TSI. 34 patients were excluded for lack of electronic data, palliative decision, or fatal condition on arrival. 12 patients out of 102 required operative management (OM) and 90 patients NOM. VTE prophylaxis was not given for 31 (30.4%). Medical reasons for this include severe brain injury and early discharge before 48 hours. VTE prophylaxis was initiated for 37 (36.3%) patients within 48 hours, and for 34 patients (33.3%) after 48 hours of admission. Seven patients developed thromboembolic events, majority of which (6/7) received VTE prophylaxis after 48 hours. Importantly, none of the patients who received VTE prophylaxis had rebleeding.
Conclusions
This study showed that early initiation of chemical VTE prophylaxis (<48h) is safe, resulted in lower incidence of DVTs/PEs without increasing the risk of bleeding. Results from this study supports recommendation from other studies 1 to initiate chemical VTE prophylaxis after TSI as early as 24h post injury with no other contra-indications.

Abstract
Abstract
Aim
Pedicle screws provide excellent fixation for a wide range of indications; their adoption in the cervical spine has been slower than in the thoracic and lumbar spine, largely due to the smaller pedicle sizes and proximity to neurovascular structures in the neck. Recent years have seen the development of technology to improve accuracy and thereby safety in cervical pedicle screw placement over traditional fluoroscopic techniques, including intraoperative 3D navigation, computer assisted systems and physical templates with screw guides. We have performed a systematic review into the accuracy rates of the various systems.
Method
PubMed and Cochrane Library databases were searched; keywords "pedicle screw cervical spine" were searched; 9 valid papers involving 1427 screws were found.
Results
Accuracy rates were 80.6% for fluoroscopy, 91.4% for navigation methods, and 96.7% for templates.
Conclusions
Superior results for templates are complemented by reduced radiation exposure to patient and surgeon; however, the technology requires prolonged pre-operative planning to create the bespoke template, and the development of an infrastructure to allow for their rapid production and delivery is needed before they become more widely available.
Two broad methods of navigation currently exist: intraoperative CT scanning providing real-time 3D navigation and preoperative CT registration in relation to a fixed reference with intraoperative computer assistance. At present, these methods are more commonly used, due to their proven improved accuracy rates over fluoroscopy, availability in emergencies and alongside minimally invasive techniques.
Despite their novelty and limitations, templates provide promising accuracy scores, although practical considerations may inhibit their proliferation.

Abstract
The aim of this study was to produce high yield of a local bacterial alkaline protease in the yeast system because the scientific involvement of microorganisms in enzyme production is still not given enough attention in Saudi Arabia. Soil samples were collected from the rhizosphere of some desert plants in Saudi Arabia. Ninety-three alkaline protease producing bacterial isolates were recovered on skimmed-milk agar at pH 9.4 and 45°C for 48 hr. Isolate D9 obtained from the rhizosphere of Heliotropium digynum at Dhahran City was the most potent isolate in respect to enzyme productivity (184.6 U/ml). The full gene of alkaline protease was amplified and showed the expected size (1300 bp). Restriction enzymes analysis also verified the integrity of the PCR product. The sequence of the protease gene revealed an open reading frame of 1329 nt correspond to the full length of the protease gene of isolate D9 encoding a 443 aa protein. After ligation of the amplified gene by the TA cloning method, digestion with appropriate restriction enzymes confirmed the integrity of the cloned gene. The insert was prepared by two PCRs that were conducted with a pair of primers specifically designed for this purpose. The digested and purified cloning vector pRS426/GAL1p-207-Glu-MS was ligated with the insert then transformed into various strains of Saccharomyces cerevisiae via the electroporation method. Maximum protease expression was done by recombinant OS303 in galactose containing media (145.5 U/ml) with an approximately 2-fold increase when compared with the wild OS303 strain., this may be due to ability to activate gal operon.

Abstract
Abstract
Aim
Gallstone related disease accounts for a third of the admissions to the Surgical Department. In June 2019, a clinical audit was undertaken at Great Western Hospital assessing the number of patients who underwent cholecystectomy, following initial diagnosis, in accordance to current guidelines. The results demonstrated a very low number of patients had cholecystectomy, within the targeted time frame, which led to the implementation of a dedicated operative “hot gallbladder” list weekly. In June 2020, we re-audit the service to evaluate the impact of the change implemented.
Method
A retrospective observational analysis of patients admitted to the Hospital in June 2020 with gallstone related disease. Data was collected using the Surgical on-call lists, these were analysed and patients selected according to the reason for admission, only gallstone related issues were considered in this analysis. Finally, via Medway, the time from admission to surgery was assessed.
Results
Despite the disruption in service provision due to COVID-19, the implementation of the “hot gallbladder” list led to a 10.7% increase in timely cholecystectomies, bringing the overall compliance to 14%. There was also a significant reduction in biliary relate re-admissions, from 58% to 37%. Despite 47.3% of patients were still awaiting surgery, the waiting list was reduced by 5.2% in only 1 year.
Conclusions
This study demonstrated that the implementation of the “hot gallbladder” list has improved the compliance with the current guidelines. The change has brought us in line with the national average of 15%, as estimated by RCSEng, therefore demonstrating the efficacy of the weekly list.

Abstract
OBJECTIVE This study evaluated the efficacy of the soluble epoxide hydrolase (sEH) inhibitor, TPPU on chronic NG-Nitro L-arginine methyl ester (L-NAME)-induced hypertension in rats and its effects on plasma Angiotensin II (Ang II), cardiac Angiotensin-converting enzyme (ACE) and Angiotensin II receptor type 1 (AT1R) expressions. MATERIALS AND METHODS Forty Sprague Dawley rats were divided into 5 groups. Two groups served as control and received orally either vehicle or TPPU (3 mg/kg) for five weeks. The other three groups were given L-NAME (50 mg/kg/day) in drinking water for five weeks. Two weeks after the L-NAME treatment, animals received orally either saline or TPPU (3 mg/kg/day) or lisinopril (10 mg/kg/day) daily for 3 weeks. Blood pressure (BP) was measured weekly. At the end of the experiment, plasma Ang II, cardiac ACE and AT1R protein and gene expressions were determined. RESULTS L-NAME caused a significant increase in BP of the animals. TPPU and lisinopril resulted in normalization of L-NAME-induced hypertension. They also caused a significant reduction in Ang II and ACE protein and gene expressions compared to L-NAME and vehicle-treated animals. CONCLUSIONS This study demonstrates that TPPU effectively lowers L-NAME-induced hypertension in rats. The mechanism of its antihypertensive effect is likely mediated by the suppression of ACE gene and protein expression, leading to a lower Ang II level.

Abstract
Juvenile fibromyalgia (JFM) syndrome is a condition under the spectrum of chronic pain syndrome. It is characterized by chronic musculoskeletal pain with multiple tender points and other associated symptoms. Diagnosis requires ruling out organic causes in addition to at least five out of 18 tender points and fulfilling three out of 10 criteria. JFM can be debilitating and overwhelming to both the patient and the physician. Management requires an incredibly careful multidisciplinary approach, including psychotherapy and physiotherapy among others.
