Project description:Chronic obstructive pulmonary disease (COPD) causes morbidity and mortality worldwide. Due to the improvement in environmental sanitation and medical care, the general life span has increased in the past decades in Japan. However, many older patients with COPD develop a wide range of comorbidities, and the impairments in the activities of daily living result in frailty and increase social and economic burdens. Population-based studies have shown that the prevalence of COPD is approximately 10% among subjects aged ≥40 years, but more than 80% of COPD patients are underdiagnosed. The Ministry of Health, Labour, and Welfare in Japan proposed the National Health Promotion in the 21st century, termed Health Japan 21 (the second term), in 2013 to prevent the onset and progression of noncommunicable diseases (NCDs), including COPD. The government, medical society, and community have been attempting to increase the recognition of COPD and promote smoking cessation. Additionally, Japanese cohorts have revealed distinct clinical features in Japanese patients with COPD, including lower rates of patient-reported exacerbations, less frequent coexisting cardiovascular disease and metabolic syndrome, and lower use of inhaled corticosteroids in Japan compared to the Western countries. Moreover, the poor adherence to inhaled medications is found in approximately 20% of subjects, and rehabilitation is performed in 26% of hospitalized patients with COPD. Therefore, more efforts should be made to improve adherence and access to pulmonary rehabilitation. Overall, Japanese COPD patients share common clinical and social features with COPD patients in other countries. Further international corroboration may help establish better comprehensive management of the disease.
Project description:Robot-assisted surgery has been progressively involved in various fields of adult and pediatric surgery, demonstrating many advantages over either mini-invasive or open surgery. The aim of this review is to provide the most recent evidence on robot-assisted pediatric surgery, in all its subspecialties. A comprehensive electronic literature search of PubMed, Embase, and Cochrane Library was conducted using appropriate Medical Subject Headings (MeSH) terms and keywords. The interval time considered was a 5-year period [2017-2022], and no language restrictions were applied. A total of 685 titles were identified. After applying exclusion criteria, 73 articles for robotic pediatric surgery have been published and were included in this review. We extrapolated and summarized the current evidence on robot-assisted surgery in pediatric age through all the fields of applicability. Robot-assisted surgery is technically feasible in case of a selected pediatric cohort, and it is going to achieve similar or better surgical results if related to the standard open or mini-invasive procedures. Copious case series and randomized trials are still required. Due to the great potential that this new technology is demonstrating, in the close future, the evolution of robotic platform will offer a valid and solid alternative in the treatment of various pediatric pathologies.
Project description:Breast reconstruction using silicone breast implants (SBIs) has been performed for many patients in Japan under the initiative of the Japan Oncoplastic Breast Surgery Society (JOBSS) since SBIs were first covered by insurance in 2013. A change in the lineup of available SBIs owing to the Allergan crisis caused a decrease in the availability of SBIs appropriate to Japanese breast contours. Recently, the number of immediate implant-based breast reconstructions (IBRs) was approximately 4,000 in one year and was slightly decreasing. The SBI is generally placed under the pectoralis major muscle. Because the number of patients with one-stage, implant-based operative indications is small, an acellular dermal matrix is not available in Japan, and the complication rate in one-stage, IBR is high, most immediate, IBRs are performed in two stages. The prevalence of immediate, one-stage, IBRs is approximately 10%. Fat grafting by injection using Coleman's technique is performed in many hospitals under the JOBSS initiative as a surgery combined with SBI insertion. Complications after SBI placement may be less common in Japan than those in other countries. Japanese breast reconstructive surgeons undertake preventive measures to lessen these complications according to guidelines and experts' opinions, which may contribute to the low complication rate after SBI placement. The total reported number of patients with breast implant-associated anaplastic large cell lymphoma is four, and no patients have died because of this disease. In Japan, procuring informed consent and diagnosing and treating this disease are performed according to the JOBSS guidelines.
Project description:The outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the related disease (COVID-19) has spread rapidly to pandemic proportions, increasing the demands on healthcare systems for the containment and management of COVID-19. One of the critical issues to be addressed is the improvement in laboratory diagnosis and screening of large portions of the population to stop the virus spreading. Currently, the laboratory diagnosis of SARS-CoV-2 infection and the related disease is based on the research of viral RNA with rt-PCR methods in upper and lower respiratory airways. Serological tests to detect SARS-CoV-2 antibodies could help physicians and healthcare workers to support COVID-19 diagnosis and follow-up and perform population screening. Our review, using MEDLINE and EMBASE, summarizes the current knowledge of direct and serological tests performed to research RNA, antigens, or antibodies for SARS-CoV-2, evaluating the advantages and drawbacks for specific tests.
Project description:New Delhi metallo-β-lactamase (NDM)-producing Enterobacterales was first detected in Brazil in 2014, in a Providencia rettgeri isolate recovered from surveillance swabs in the Southern region. Since then, an increasing number of NDM enzymes have been reported in different species. Nevertheless, comprehensive data on the current epidemiology of NDM-producing Enterobacterales in Brazil are lacking. Therefore, this study reviewed the available information on the status of NDM-producing bacteria in Brazil. The main finding was the diversity of bacteria producing NDM, including Klebsiella, Enterobacter, Morganella, Proteus, Escherichia, and Providencia. Limited data on clonality are available, but a few studies report different clonal backgrounds in NDM-producing K. pneumoniae, likely indicating local outbreaks. Over the years, a rise in the number of reported strains in different locations has been verified; however, different biases may have contributed to this finding. Therefore, a national surveillance study is warranted to identify the actual prevalence and incidence of NDM-producing Enterobacterales in Brazil and their role in patient management and outcome.
Project description:Background and objectiveNeuroblastoma (NB) is a common malignant tumor in children, and its treatment remains challenging. Precision medicine, as an individualized treatment strategy, aims to improve efficacy and reduce toxicity by combining unique patient- and tumor-related factors, bringing new hope for NB treatment. In this article, we review the evidence related to precision medicine in NB, with a focus on potential clinically actionable targets and a series of targeted drugs associated with NB.MethodsWe conducted an extensive search in PubMed, EMBASE, and Web of Science using key terms and database-specific strategies, filtered for time and language, to ensure a comprehensive collection of literature related to precision medicine in NB. The main search terms consisted of "neuroblastoma", "precision medicine", "pediatrics", and "targeting". The articles included in this study encompass those published from 1985 to the present, without restrictions on the type of articles.Key content and findingsALK inhibitors and MYCN inhibitors have been developed to interfere with tumor cell growth and dissemination, thereby improving treatment outcomes. Additionally, systematic testing to identify relevant driver mutations is crucial and can be used for diagnosis and prognostic assessment through the detection of many associated molecular markers. Furthermore, liquid biopsy, a non-invasive tumor detection method, can complement tissue biopsy and play a role in NB by analyzing circulating tumor DNA and circulating tumor cells to provide genetic information and molecular characteristics of the tumor. Recently, trials conducted by many pediatric oncology groups have shown the urgent need for new approaches to cure relapsed and refractory patients.ConclusionsThe purpose of this review is to summarize the latest advances in clinical treatment of NB, to better understand and focus on the development of promising treatment approaches, and to expedite the transition to the precision medicine clinical relevance in NB patients.
Project description:Gender-affirming surgery (GAS) is often a crucial step during the journey to identity actualization for transgender patients. Surgical breast augmentation, or "top surgery", is frequently cited as the most important and sometimes only gender-affirming procedure sought by transfeminine patients. The breast augmentation process is remarkably similar in transgender and cisgender patients. However, there are unique guidelines, anatomic considerations, and contextual issues for the transgender patient population that must be taken into account by providers to achieve optimal outcomes. The aim of this review is to outline the current state of breast augmentation for transfeminine patients. We walk through our suggested pre-surgical evaluation, breast augmentation options, and post-surgical care. In the preoperative period, providers must establish a positive provider-patient relationship that allows for thorough history taking, physical examination, and goal setting. Providers must be able to select an appropriate implant, incision location, and operative plane to balance patient desires and pre-existing anatomic characteristics in transfeminine patients. Postoperatively, the provider must address acute and chronic needs to allow for continued satisfaction and safety. After reading this review, we aim for providers to be well-equipped to provide the highest quality breast augmentation care for their transfeminine patients. As research into best practices for breast augmentation in transfeminine patients continues to develop, we expect that surgical practice will continue to evolve.
Project description:Background and objectivePatients with metastatic anaplastic lymphoma kinase (ALK)+ non-small cell lung cancer (NSCLC) often experience years of disease control on targeted therapies but the disease eventually develops resistance and progresses. Multiple clinical trial efforts to incorporate PD-1/PD-L1 immunotherapy into the treatment paradigm for ALK+ NSCLC have resulted in significant toxicities without clear improvement in patient outcomes. Observations from clinical trials, translational studies, and preclinical models suggest the immune system interacts with ALK+ NSCLC and this interaction is heightened with the initiation of targeted therapy. The objective of this review is to summarize knowledge to date about current and potential immunotherapy approaches for patients with ALK+ NSCLC.MethodsTo identify the relevant literature and clinical trials the databases PubMed.gov and ClinicalTrials.gov were queried with keywords "ALK" and "lung cancer". PubMed search was further refined with terms such as "immunotherapy", "tumor microenvironment or TME", "PD-1", and "T cells". The search for clinical trials was limited to interventional studies.Key content and findingsIn this review, the current status of PD-1/PD-L1 immunotherapy for ALK+ NSCLC is updated and alternative immunotherapy approaches are highlighted in the context of available patient level and translational data on the ALK+ NSCLC tumor microenvironment (TME). An increase in CD8+ T cells within the ALK+ NSCLC TME has been observed with targeted therapy initiation across multiple studies. Therapies to augment this including tumor infiltrating lymphocyte (TIL) therapy, modified cytokines, and oncolytic viruses are reviewed. Furthermore, the contribution of innate immune cells in TKI mediated tumor cell clearance is discussed as a future target for novel immunotherapy approaches that promote cancer cell phagocytosis.ConclusionsImmune modulating strategies derived from current and evolving knowledge of the ALK+ NSCLC TME may have a role in ALK+ NSCLC beyond PD-1/PD-L1 based immunotherapy.
Project description:Vitamin D testing and the use of vitamin D supplements have increased substantially in recent years. Currently, the role of vitamin D supplementation, and the optimal vitamin D dose and status, is a subject of debate, because large interventional studies have been unable to show a clear benefit (in mostly vitamin D replete populations). This may be attributed to limitations in trial design, as most studies did not meet the basic requirements of a nutrient intervention study, including vitamin D-replete populations, too small sample sizes, and inconsistent intervention methods regarding dose and metabolites. Vitamin D deficiency (serum 25-hydroxyvitamin D [25(OH)D] < 50 nmol/L or 20 ng/ml) is associated with unfavorable skeletal outcomes, including fractures and bone loss. A 25(OH)D level of >50 nmol/L or 20 ng/ml is, therefore, the primary treatment goal, although some data suggest a benefit for a higher threshold. Severe vitamin D deficiency with a 25(OH)D concentration below <30 nmol/L (or 12 ng/ml) dramatically increases the risk of excess mortality, infections, and many other diseases, and should be avoided whenever possible. The data on a benefit for mortality and prevention of infections, at least in severely deficient individuals, appear convincing. Vitamin D is clearly not a panacea, and is most likely efficient only in deficiency. Given its rare side effects and its relatively wide safety margin, it may be an important, inexpensive, and safe adjuvant therapy for many diseases, but future large and well-designed studies should evaluate this further. A worldwide public health intervention that includes vitamin D supplementation in certain risk groups, and systematic vitamin D food fortification to avoid severe vitamin D deficiency, would appear to be important. In this narrative review, the current international literature on vitamin D deficiency, its relevance, and therapeutic options is discussed.
Project description:Background and objectiveBreast reconstruction with microsurgical techniques allows for autologous reconstruction after mastectomy without the complications associated with alloplastic reconstruction. Autologous reconstruction has undergone significant improvement and now offers patients a variety of options depending on patient specific factors and aesthetic outcomes. This review aims to focus on the history of autologous reconstruction, operative considerations, general surgical techniques for flaps, and indications for choosing the ideal free tissue transfer for all medical specialties and not only plastic surgeons.MethodsA comprehensive review of the literature was performed using PubMed and Embase databases. Manuscripts that provided objective data with respect to history of microsurgical options, surgical techniques, patient considerations, and contraindications were utilized for this review with the objective to simplify data for all non-plastic surgeon readers.Key content and findingsIn this study, we find that patient selection is critical in successful outcomes for microsurgical breast reconstruction. We find that abdominal free flaps are now considered gold standard for autologous reconstruction. However, reliable alternatives exist for patients who are not considered ideal candidates for this reconstruction. These include thigh-based flaps such as gracilis myocutaneous flaps, profunda artery perforator flaps, lateral thigh perforator flaps and trunk-based flaps such as lumbar artery perforator flap. Postoperative considerations involve clinical monitoring and enhanced recovery after surgery. The rate of reconstructive success and flap viability is greater that 95%, even in high-risk populations, and therefore risk stratification should be performed based on an individual basis. While there are no absolute contraindications to autologous reconstruction, relative contraindications do exist including obesity and elderly populations due to the increased surgical and medical complications.ConclusionsWhile implant-based reconstruction remains the predominant method of breast reconstruction in the United States, there have been many exciting advancements in autologous reconstruction that offers high aesthetic outcomes and patient satisfaction.
