RESUMEN
This study provides a comprehensive overview of hereditary hemochromatosis (HH), a genetic condition characterized by iron overload due to excessive iron absorption. It elucidates diverse inheritance patterns and clinical manifestations by exploring mutations in critical genes such as HFE (hemochromatosis), HJV (hemojuvelin), HAMP (hepcidin antimicrobial peptide), TfR2 (transferrin receptor 2), and FP (ferroportin). The significance of early screening, diagnosis, and personalized management strategies based on genetic classification is emphasized, particularly in terms of high-income vs. low-income countries. Addressing challenges in diagnosis, genetic testing accessibility, and healthcare disparities, the study highlights the importance of early detection, cost-effective screening strategies, and enhancing healthcare outcomes globally. Advanced genetic testing in high-income countries facilitates early diagnosis and management, reducing complications such as liver disease and cardiomyopathy. In contrast, low-income populations face several barriers, including limited access to genetic testing, high costs, and inadequate healthcare infrastructure. Cost-effective serum ferritin (SF) and transferrin saturation (TS) tests and emerging point-of-care (POC) tests offer affordable diagnostic options for low-resource settings. Additionally, the ongoing development of hepcidin measurement methods holds promise for enhancing diagnostic capabilities. Implementing these strategies can aid healthcare providers in improving global HH management and reducing the burden of iron overload complications. Furthermore, the study underscores the need for public health initiatives to raise awareness about HH, promote routine screenings, and advocate for equitable healthcare policies. Collaborative efforts between governments, healthcare organizations, and research institutions are crucial in addressing the global burden of HH. By fostering international cooperation and resource-sharing, it is possible to bridge the gap between high-income and low-income countries, ensuring all individuals have access to the necessary diagnostic and treatment options. This holistic approach can ultimately lead to better health outcomes and improved quality of life for individuals affected by HH worldwide. This comprehensive examination of HH not only illuminates the genetic and clinical aspects of the condition but also provides a roadmap for addressing the multifaceted challenges associated with its diagnosis and management.
RESUMEN
Pancreatoduodenectomy, the primary surgical strategy for managing cholangiocarcinoma, is executed via two distinct methodologies, namely minimally invasive pancreatoduodenectomy (MIPD) and open pancreatoduodenectomy (OPD). The selection between these surgical options is critical, as it directly influences patient outcomes, encompassing both short-term recovery metrics and long-term survival rates. Despite the clinical significance of these procedures, there exists a notable void in the literature regarding a comprehensive comparison of MIPD and OPD, particularly in assessing their respective efficacies and complications. This lack of detailed comparative analysis has left a gap in evidence-based guidance for clinicians faced with the decision of choosing the most appropriate surgical approach for their patients. The absence of robust data comparing the two techniques underscores the necessity for a meta-analysis that rigorously examines and contrasts the outcomes associated with MIPD and OPD. By drawing upon a wide array of international studies, this research aims to shed light on the advantages and potential drawbacks of each method, thereby providing a more informed basis for surgical decision-making in the treatment of cholangiocarcinoma.
RESUMEN
Esophageal varices (EVs), a significant complication of cirrhosis, present a considerable challenge in clinical practice due to their high risk of bleeding and associated morbidity and mortality. This manuscript explores the transformative role of artificial intelligence (AI) in the management of EV, particularly in enhancing diagnostic accuracy and predicting bleeding risks. It underscores the potential of AI in offering noninvasive, efficient alternatives to traditional diagnostic methods such as esophagogastroduodenoscopy (EGD). The complexity of EV management is highlighted, necessitating a multidisciplinary approach that includes pharmacological therapy, endoscopic interventions, and, in some cases, surgical options tailored to individual patient profiles. Additionally, the paper emphasizes the importance of integrating AI into medical education and practice, preparing healthcare professionals for the evolving landscape of medical technology. It projects a future where AI significantly influences the management of gastrointestinal bleeding, improving clinical decision-making, patient outcomes, and overall healthcare efficiency. The study advocates for a patient-centered approach in healthcare, balancing the incorporation of innovative technologies with ethical principles and the diverse needs of patients to optimize treatment efficacy and enhance healthcare accessibility.
RESUMEN
In this systematic review, the perioperative outcomes of total intravenous anesthesia (TIVA) and volatile anesthesia were compared in obese adults (BMI ≥ 30 kg/m²) undergoing elective surgery. The review analyzed data from 12 randomized-controlled trials involving 935 patients, sourced from PubMed/MEDLINE (Medical Literature Analysis and Retrieval System Online), Cochrane, Scopus, and Web of Science databases. The focus was on intraoperative vital signs, emergence time, postoperative nausea and vomiting (PONV), duration of post-anesthesia care unit (PACU) stay, and ICU admission rates. Findings showed that TIVA (using propofol) might reduce PONV, but there were no significant differences in other outcomes compared to volatile anesthesia (with desflurane as the most common agent). The review highlights the need for more research, especially comparing sevoflurane with TIVA, to establish clear clinical guidelines for anesthesia in obese patients.
RESUMEN
Nutritional deficiencies represent a prevalent concern among individuals with obesity, stemming from suboptimal dietary habits, chronic inflammation, and preoperative weight reduction efforts. Bariatric surgical interventions, employing either restrictive, malabsorptive or a combination of the two methods, further compound these deficiencies. Commonly observed nutritional deficits following bariatric surgeries include vitamin B12, vitamin D, thiamine, folate, iron, and protein deficiencies. These deficiencies are further complicated by disparities in healthcare resources and income that distinguish low, medium, and high-income countries. The escalating rates of obesity in low- and medium-income countries are primarily attributed to the increasing availability of cheap, nutritionally depleted, and processed foods, coupled with limited access to healthcare. The provision of bariatric surgical interventions in such regions is hindered by the lack of appropriately trained medical personnel and adequate infrastructure. Additionally, the crucial facets of postoperative care, including diligent follow-up, precise weight loss monitoring, and the administration of appropriate nutritional supplements, often remain lacking. This narrative review provides a comprehensive examination of the prevention and treatment of nutritional deficiencies before and after bariatric surgery in the context of varying healthcare resources and income levels. Bariatric procedures and their global prevalence are discussed, and the prevalence, symptoms, and management strategies of specific nutritional deficiencies are explained. This review also outlines practical strategies for providing more equitable care in low- and medium-income countries.
RESUMEN
Inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, is a chronic condition characterized by inflammation of the gastrointestinal tract. Its exact cause is unknown, but it's thought to result from a dysregulated immune response influenced by various factors, including changes in the intestinal microbiota, diet, lifestyle, and genetics. The gut microbiome, consisting of diverse microorganisms, plays a crucial role in maintaining physiological balance, with its disruption leading to inflammatory responses typical of IBD. Treatments primarily aim at symptom control, employing immunomodulators, corticosteroids, and newer approaches like probiotics, prebiotics, fecal transplants, and dietary modifications, all focusing on leveraging the microbiota's potential in disease management. These strategies aim to restore the delicate balance of the gut microbiome, typically altered in IBD, marked by a decrease in beneficial bacteria and an increase in harmful pathogens. This review underscores the importance of the gut microbiome in the pathogenesis and treatment of IBD, highlighting the shift towards personalized medicine and the necessity for further research in understanding the complex interactions between the gut microbiota, immune system, and genetics in IBD. It points to the potential of emerging treatments and the importance of a multifaceted approach in managing this complex and challenging disease.
RESUMEN
Nasal congestion is a common issue stemming from various factors such as allergies and anatomical variations. Allergic rhinitis frequently leads to nasal congestion. The pathophysiology involves inflammation, swelling, and mucus production in the nasal mucosa. Multiple treatments are available, including oral phenylephrine, an over-the-counter or prescription option. However, the effectiveness and safety of phenylephrine have been subjects of debate. This systematic review aims to provide an updated perspective on the efficacy of oral phenylephrine versus placebo in addressing nasal congestion in adults. We conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines, a systematic review involving searches on PubMed, Cochrane, and Scopus databases. Inclusion/exclusion criteria were defined to identify high-quality studies. The focus was on randomized controlled trials (RCTs) and case-control studies published in English between 1998 and 2023, involving adult populations. The interventions compared oral phenylephrine with placebo or standard care, with outcomes centering on changes in nasal congestion symptoms and nasal airway resistance. We identified four articles that met the criteria. These studies exhibited varied designs and populations. The findings consistently indicated that phenylephrine was not more effective than a placebo in relieving nasal congestion. This systematic review demonstrates that oral phenylephrine did not offer substantial relief from nasal congestion compared to a placebo in adults. The studies featured diverse designs, yet the prevailing conclusion was that phenylephrine's efficacy was limited. Safety assessments showed no life-threatening adverse events, with common side effects including headaches and mild discomfort. In summary, this systematic review indicates that oral phenylephrine is not significantly more effective than a placebo in alleviating nasal congestion in adults. Clinicians should explore alternative treatment options, considering the review's limitations. Additional research may be needed to clarify the role of oral phenylephrine in managing nasal congestion.
