Summary: Improved diagnostic methods and medical therapies are necessary for early detection and treatment and an improved prognosis. It is thus vital to both examine and evaluate the role of the various existing proteins as biomarkers in carcinogenesis and to assess the contribution of these proteins in anti-cancer activity, for consideration in therapeutic strategies. It is essential to both examine and evaluate the role of the various existing proteins as biomarkers in carcinogenesis and to assess the contribution of these proteins in anti-cancer activity, for consideration in therapeutic strategies. The purpose of this review is twofold. Firstly, it is to evaluate recent data about which proteins can be utilized as biomarkers in carcinogenesis. The proteins reviewed include: CPTP, IL-6, CCN, and S100. Secondly, it is to evaluate the contribution of dietary proteins in cancer activity. Specifically, how whey protein, soy proteins and lectin, a phytochemical could be useful in cancer prevention and treatment.Recent Findings: Whey protein, present in dairy products, is an excellent source of the sulphur amino acid cysteine, the rate limiting substrate in glutathione synthesis. Notably, this protein survives digestion and has been shown to have anti-carcinogenic properties in animal studies. Lectins are phytochemicals present in plant foods, and have active components which alters cancer initiation, promotion and progression. Lectins have been characterized as a useful tool in biochemistry, cell biology, immunology and in diagnostic and therapeutic purposes in cancer research. Soy proteins contain various compounds, including isoflavones, protease inhibitors and protein kinase inhibitors, which have been proven effective in tumor growth inhibition. They have therefore, been greatly emphasized in cancer prevention and treatment. It has been proved that soy food consumption was associated with decreased risk of death and recurrence of breast cancer. CPTP is a recently discovered protein whose main role is to transport C1P, a pro-inflammatory molecule. The discovery of CPTP may shine a light on the mechanism of inflammatory diseases, and hopefully offer a potential target for therapeutic purposes in cancer research. Interleukin-6 is a multifunctional cytokine that affects the activity of cancer cells. It is involved in tumor growth, and elevated levels is associated with an increased risk of cancer. S100B is a well-established biomarker for malignant melanoma, and useful in assessing tumor load, stage and prognosis for patients with this disease. Other members of this family of proteins include S100A4, which has been associated with several malignancies and S100A2, which has been found to be decreased in some cancers. CCN are a group of regulatory proteins, located in the extracellular matrix (maricellular). They are involved in cellular adhesion, mitogenesis, chemotaxis, cell survival, and wound healing. CCN proteins are also able to modulate the signals of several proteins, which may also influence skeletal develo...
The novel coronavirus has negatively affected patients and healthcare systems globally. Individuals with coronavirus disease 2019 (COVID-19) experience a wide range of respiratory symptoms, from mild flu-like symptoms to severe and potentially fatal pneumonia. Some patients report gastrointestinal symptoms, such as nausea, vomiting and abdominal pain in addition to the respiratory symptoms or as a separate presentation. Even though abdominal pain syndrome indicates acute appendicitis, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection should be considered as a possible diagnosis during this pandemic. However, there have been reports of a few cases of acute abdominal pain revealing acute appendicitis associated with SARS-CoV-2 infection. Appendectomy is challenging in COVID-19-infected patients with acute appendicitis as it includes high surgical risks for the patients, as well as hazards for healthcare professionals who are exposed to SARS-CoV-2. The present study reports five cases of adult patients with COVID-19 with simultaneous acute appendicitis. In addition, the present study aims to provide the framework for the diagnosis and management of adult patients with COVID-19 with acute appendicitis.
Novel coronavirus infection presents with greater severity in individuals with comorbid chronic lung diseases. Bronchiectasis is an illness characterized by permanent enlargement of the airways, presenting with chronic cough and sputum production and vulnerability to lung infections. Bronchiectasis is not a common comorbid disease in patients with COVID-19 disease and bronchiectasis exacerbation rates were decreased during the pandemic. However, COVID-19 disease is associated with worse outcomes in patients with bronchiectasis and patients with bronchiectasis are more susceptible to SARS-CoV-2 infection development. Pseudomonas putida is an opportunistic pathogen, causing infections mostly in immunocompromised hosts and is not a frequent bacterial colonizer in patients with bronchiectasis. This present study reports a rare case of exacerbation of bronchiectasis by Pseudomonas putida complicating COVID-19 disease in an immunocompetent 70-year-old woman. Clinicians should be aware that SARS-CoV-2 infection is probably a precipitating factor of bronchiectasis exacerbation while bronchiectasis is a risk factor for greater severity of SARS-CoV-2 infection.
Swyer-James-Macleod syndrome is an infrequent clinical condition characterized by unilateral hyperlucent lung as a complication following infectious bronchiolitis obliterans, typically diagnosed during childhood. However, in some patients, the diagnosis may be confirmed in adulthood. The syndrome can be misdiagnosed with other lung disorders such as asthma, pulmonary embolism, and pneumothorax, leading to inappropriate management and worse outcome. We present a case of Swyer-James-MacLeod syndrome, diagnosed in a 63-year-old man, with frequent hospitalisations due to chronic obstructive pulmonary disease (COPD) exacerbations without a history of significant lung infection in childhood. Complications of Swyer-James-MacLeod syndrome include recurrent infections, lung abscess, pneumothorax, and pulmonary hypertension. The syndrome should always be considered in adults with recurrent respiratory infections or pulmonary hyperlucency on chest imaging to prevent a delay in correct diagnosis and improper treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
