RESUMO
OBJECTIVE: Surgical decompression via transaxillary first rib resection (TFRR) is often performed in patients presenting with venous thoracic outlet syndrome (VTOS). We aimed to evaluate the outcomes of TFRR based on chronicity of completely occluded axillosubclavian veins in VTOS. METHODS: We performed a retrospective institutional review of all patients who underwent TFRR for VTOS and had a completely occluded axillosubclavian vein between 2003 and 2022. Patients were categorized into three groups based on the time of inciting VTOS event to TFRR acuity of their venous occlusion: <4 weeks, 4 to 12 weeks, and >12 weeks. We evaluated the association of TFRR timing with 1-year outcomes, including patency and symptomatic improvement. We used the χ2 test to compare baseline characteristics and postoperative outcomes. RESULTS: Overall, 103 patients underwent TFRR for VTOS with a completely occluded axillosubclavian vein (median age, 30.0 years; 42.7% female; 8.8% non-White), of whom 28 had occlusion at <4 weeks, 36 had occlusion at 4 to 12 weeks, and 39 had occlusion at >12 weeks. Postoperative venogram performed 2 to 3 weeks after TFRR demonstrated that 78.6% in the <4 weeks group, 72.2% in the 4- to 12-weeks group, and 61.5% in the >12 weeks group had some degree of recanalization (P = .76). Postoperative balloon angioplasty was successfully performed in 60 patients with stenosed or occluded axillosubclavian vein at the time of postoperative venogram. At the 10- to 14-month follow-up, 79.2% of the <4 weeks group, 73.3% of the 4- to 12-weeks group, and 73.3% of the >12 weeks group had patent axillosubclavian veins based on duplex ultrasound examination (P = .86). Among patients who underwent postoperative balloon angioplasty, 80.0%, 85.0% and 100% in the <4 weeks, 4- to 12-weeks, and >12 weeks groups respectively demonstrated patency at 10 to 14 months (P = .31). Symptomatic improvement was reported in 95.7% in the <4 weeks group, 96.7% in the 4- to 12-weeks group, and 93.5% in the >12 weeks group (P = .84). CONCLUSIONS: TFRR offers excellent postoperative outcomes for patients with symptomatic VTOS, even in cases of completely occluded axillosubclavian veins, regardless of the chronicity of the occlusion. By 14 months, 95.2% of patients experienced symptomatic improvement, and 75% attained venous patency.
RESUMO
Arterial thoracic outlet syndrome (aTOS) is a rare, but potentially, limb-threatening condition that is often misdiagnosed. We present the case of a 29-year-old man who was initially managed under the presumption of primary Raynaud's phenomenon for >1 year before the correct diagnosis of aTOS, and the delay in diagnosis was complicated by substantial distal thromboembolic occlusion. Successful staged treatment included thoracic outlet decompression, subclavian artery aneurysm repair with subclavian-to-axillary bypass, anticoagulation, and an unconventional axillary-to-ulnar artery bypass. This report highlights the diagnostic challenges of aTOS and the importance of considering it in patients with Raynaud's phenomenon and vaso-occlusive symptoms.
RESUMO
Alzheimer's disease (AD) constitutes a multifactorial neurodegenerative pathology characterized by cognitive deterioration, personality alterations, and behavioral shifts. The ongoing brain impairment process poses significant challenges for therapeutic interventions due to activating multiple neurotoxic pathways. Current pharmacological interventions have shown limited efficacy and are associated with significant side effects. Approaches focusing on the early interference with disease pathways, before activation of broad neurotoxic processes, could be promising to slow down symptomatic progression of the disease. Curcumin-an integral component of traditional medicine in numerous cultures worldwide-has garnered interest as a promising AD treatment. Current research indicates that curcumin may exhibit therapeutic potential in neurodegenerative pathologies, attributed to its potent anti-inflammatory and antioxidant properties. Additionally, curcumin and its derivatives have demonstrated an ability to modulate cellular pathways via epigenetic mechanisms. This article aims to raise awareness of the neuroprotective properties of curcuminoids that could provide therapeutic benefits in AD. The paper provides a comprehensive overview of the neuroprotective efficacy of curcumin against signaling pathways that could be involved in AD and summarizes recent evidence of the biological efficiency of curcumins in vivo.

Necrotizing fasciitis is an uncommon yet fatal soft tissue infection. Current recommended treatment includes antibiotics with repeat surgical exploration and wound debridement followed by reconstruction. In burn patients, the Meek micrograft has demonstrated a higher true expansion ratio, faster reepithelialization rate, more resilient toward infection, and reduced risk of graft failure as compared with meshed graft. To our best knowledge, the use of Meek micrografting technique in reconstruction of postdebridement wounds of necrotizing fasciitis has not been reported. Hereby, we present a case of a 57-year-old gentleman who was referred to us for wound reconstruction after surgical debridement of Fournier's gangrene and extensive necrotizing fasciitis involving the anterior abdomen and bilateral femoral region. Meek micrografting technique was used to reconstruct the anterior abdomen as the wound bed was large. Although the graft was complicated with a small area of localized infection, it did not spread across the entire graft and was successfully treated with topical antibiotics and regular wound dressing. In our case, wound reconstruction using Meek micrografting technique in a patient with extensive necrotizing fasciitis was successful and showed positive outcome. Therefore, we suggest further studies to be conducted to investigate the applications and outcomes of the Meek micrografting technique, especially in patients with extensive wound bed and limited donor site availability.
RESUMO
The circadian rhythm (CR) is a fundamental biological process regulated by the Earth's rotation and solar cycles. It plays a critical role in various bodily functions, and its dysregulation can have systemic effects. These effects impact metabolism, redox homeostasis, cell cycle regulation, gut microbiota, cognition, and immune response. Immune mediators, cycle proteins, and hormones exhibit circadian oscillations, supporting optimal immune function and defence against pathogens. Sleep deprivation and disruptions challenge the regulatory mechanisms, making immune responses vulnerable. Altered CR pathways have been implicated in diseases such as diabetes, neurological conditions, and systemic autoimmune diseases (SADs). SADs involve abnormal immune responses to self-antigens, with genetic and environmental factors disrupting self-tolerance and contributing to conditions like Systemic Lupus Erythematosus, Rheumatoid Arthritis, and Inflammatory Myositis. Dysregulated CR may lead to increased production of pro-inflammatory cytokines, contributing to the systemic responses observed in SADs. Sleep disturbances significantly impact the quality of life of patients with SADs; however, they are often overlooked. The relationship between sleep and autoimmune conditions, whether causal or consequential to CR dysregulation, remains unclear. Chrono-immunology investigates the role of CR in immunity, offering potential for targeted therapies in autoimmune conditions. This paper provides an overview of the connections between sleep and autoimmune conditions, highlighting the importance of recognizing sleep disturbances in SADs and the need for further research into the complex relationship between the CR and autoimmune diseases.

With increasing prevalence and an expected rise in disease burden, cancer is a cause of concern for African healthcare. The cancer burden in Africa is expected to rise to 2.1 million new cases per year and 1.4 million deaths annually by the year 2040. Even though efforts are being made to improve the standard of oncology service delivery in Africa, the current state of cancer care is not yet on par with the rise in the cancer burden. Cutting-edge technologies and innovations are being developed across the globe to augment the battle against cancer; however, many of them are beyond the reach of African countries. Modern oncology innovations targeted to ward Africa would be promising to address the high cancer mortality rates. The innovations should be cost-effective and widely accessible to tackle the rapidly rising mortality rate on the African continent. Though it may seem promising, a multidisciplinary approach is required to overcome the challenges associated with the development and implementation of modern oncology innovations in Africa.

The emergence of genome-wide association studies (GWAS) has identified genetic traits and polymorphisms that are associated with the progression of nonalcoholic fatty liver disease (NAFLD). Phospholipase domain-containing 3 and transmembrane 6 superfamily member 2 are genes commonly associated with NAFLD phenotypes. However, there are fewer studies and replicability in lesser-known genes such as LYPLAL1 and glucokinase regulator (GCKR). With the advent of artificial intelligence (AI) in clinical genetics, studies have utilized AI algorithms to identify phenotypes through electronic health records and utilize convolution neural networks to improve the accuracy of variant identification, predict the deleterious effects of variants, and conduct phenotype-to-genotype mapping. Natural language processing (NLP) and machine-learning (ML) algorithms are popular tools in GWAS studies and connect electronic health record phenotypes to genetic diagnoses using a combination of international classification disease (ICD)-based approaches. However, there are still limitations to machine-learning - and NLP-based models, such as the lack of replicability in larger cohorts and underpowered sample sizes, which prevent the accurate prediction of genetic variants that may increase the risk of NAFLD and its progression to advanced-stage liver fibrosis. This may be largely due to the lack of understanding of the clinical consequence in the majority of pathogenic variants. Though the concept of evolution-based AI models and evolutionary algorithms is relatively new, combining current international classification disease -based NLP models with phylogenetic and evolutionary data can improve prediction accuracy and create valuable connections between variants and their pathogenicity in NAFLD. Such developments can improve risk stratification within clinical genetics and research while overcoming limitations in GWAS studies that prevent community-wide interpretations.
RESUMO
The tremendous evolution in modern technology has led to a paradigm shift in neurosurgery. The latest advancements such as augmented reality, virtual reality, and mobile applications have been incorporated into neurosurgical practice. NeuroVerse, representing the application of the metaverse in neurosurgery, brings enormous potential to neurology and neurosurgery. Implementation of NeuroVerse could potentially elevate neurosurgical and interventional procedures, enhance medical visits and patient care, and reshape neurosurgical training. However, it is also vital to consider the challenges that may be associated with its implementation, such as privacy issues, cybersecurity breaches, ethical concerns, and widening of existing healthcare inequalities. NeuroVerse adds phenomenal dimensions to the neurosurgical environment for patients, doctors, and trainees, and represents an incomparable advancement in the delivery of medicine. Therefore, more research is needed to encourage widespread use of the metaverse in healthcare, particularly focusing on the areas of morality and credibility. Although the metaverse is expected to expand rapidly during and after the COVID-19 pandemic, it remains to be seen whether it represents an emerging technology that will revolutionize our society and healthcare or simply an immature condition of the future.

The Russian invasion of Ukraine is a humanitarian disaster. It has a wide-ranging impact on the livelihood and the health of those affected by the war. In the midst of constant shelling and casualties, children are more vulnerable to injuries, infections, malnutrition, and trauma, all of which can have serious consequences for their physical and mental health. Children, unlike adults, are simply subjected to the horrors of war with no pre-existing ability to deal with the consequences. We hope to highlight the effects of the current Ukrainian war on the health of the paediatric population, with a particular emphasis on surgical care, cancer care, infectious disease, to name a few. We hope to help contextualize future data and encourage the development of a system to protect and serve the war's most vulnerable population.
RESUMO
The COVID-19 pandemic had a significant impact on several aspects of global healthcare systems, particularly surgical services. New guidelines, resource scarcity, and an ever-increasing demand for care have posed challenges to healthcare professionals, resulting in the cancellation of many surgeries, with short and long-term consequences for surgical care and patient outcomes. As the pandemic subsides and the healthcare system attempts to reestablish a sense of normalcy, surgical recommendations and advisories will shift. These changes, combined with a growing case backlog (postponed surgeries + regularly scheduled surgeries) and a physician shortage, can have serious consequences for physician health and, as a result, surgical care. Several initiatives are already being implemented by governments to ensure a smooth transition as surgeries resume. Newer and more efficient steps aimed at providing adequate surgical care while preventing physician burnout, on the other hand, necessitate a collaborative effort from governments, national medical boards, institutions, and healthcare professionals. This perspective aims to highlight alterations in surgical recommendations over the course of the pandemic and how these changes continue to influence surgical care and patient outcomes as the pandemic begins to soften its grip.
