Adult-onset food allergy (AOFA), referring to food allergies that first develop in adulthood, has received growing attention in recent years, reflecting the broader rise of immunoglobulin E (IgE)-mediated food allergies. Despite limited dedicated research, a small but expanding body of observational and clinical data offers insight into its characteristics, particularly the frequency of implicated allergens. In this narrative review, the widely cited claim that shellfish are the most common allergen associated with AOFA is critically examined. To assess this claim, relevant peer-reviewed observational studies, published in English and primarily indexed in the PubMed database between 2000 and 2025, were reviewed. Studies were selected based on their focus on adult populations and the availability of specific allergen data.Shellfish were consistently identified as one of the most frequently reported allergens in multiple studies conducted across diverse geographic regions. However, substantial variation in study design, population characteristics, diagnostic criteria, and reporting practices hindered direct comparisons. Variability in reported prevalence rates and methodological differences further complicated interpretation. Additionally, limitations such as reliance on self-reported diagnoses and inconsistent use of diagnostic tests were identified as factors that limit the generalizability of current findings.In summary, although shellfish are frequently reported as a leading allergen in AOFA, current evidence remains inconclusive. Misidentification of the most prevalent allergens could potentially influence clinical guidance and public health interventions. The need for rigorous, large-scale epidemiological studies employing standardized definitions and diagnostic protocols is therefore emphasized. A clearer understanding of allergen prevalence in AOFA will enable more effective clinical risk assessments and support the development of targeted public health strategies.

Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. Leptin and ghrelin are important markers in PCOS due to their correlation with obesity, insulin resistance, and fertility. There is currently a debate in the literature about whether altered leptin and ghrelin levels in women with PCOS are a result of the disease itself or if they are due to factors such as the hyperinsulinemic state characteristic of PCOS. This meta-analysis aims to assess if insulin levels impact leptin and ghrelin levels in PCOS. Eight case-control studies assessing the relationship between insulin and leptin, as well as five case-control studies assessing the relationship between insulin and ghrelin, were identified in PubMed. Pearson's correlation coefficient (PCC) and the sample size were extracted, and two meta-analyses were conducted using a random-effects model. Total heterogeneity (I2) with a confidence interval of 95% was then determined. "Leave-one out" diagnostics were calculated for each case. If a study was identified as being significantly influential, the study was removed from the data set, and the trim and fill procedure was applied. Publication bias was assessed using Egger's regression test and rank correlation test. Our results showed a moderate positive relationship (r=0.56, 95% confidence interval (CI) (0.42, 0.71), with substantial heterogeneity I2=81.35%, 95% CI (25.2799, 88.2451)) between insulin and leptin levels, and a moderate negative relationship (r=-0.33, 95% CI (-0.43, -0.24)), with low heterogeneity (I2=0.00%, 95% CI (0.0000, 80.8159)) between insulin and ghrelin levels. Therefore, there is a significant relationship between insulin and higher leptin and lower ghrelin levels in women with PCOS. Better insulin control may have a positive effect on fertility, appetite, weight, body image, and quality of life in these women. This correlation is likely multifactorial, and further studies are needed to isolate factors influencing these hormones.

The use of artificial intelligence (AI) in healthcare analytics has brought about a transformation in the medical field of diagnosis and treatment optimization. AI technologies have unmatched abilities in processing substantial amounts of medical data and extracting valuable insights by combining big data analytics and advanced machine learning algorithms. AI algorithms provide healthcare professionals with enhanced accuracy and speed in diagnosing illnesses, predicting patient results, and tailoring treatment plans across the entire healthcare journey. This abstract explores how artificial intelligence (AI) can revolutionize healthcare analytics in various areas such as genomics, electronic health records (EHRs), medical imaging, and clinical decision support systems. Healthcare providers can improve healthcare services by optimizing workflows, enhancing patient outcomes, and using AI-driven initiatives to make services more accessible and high in quality. In order to ensure ethical and accountable use of AI in healthcare, it is necessary to address problems such as algorithm bias, data privacy worries, and regulatory obstacles. Despite these challenges, the ongoing advancement of AI technologies has vast potential to transform patient care models and healthcare delivery methods.

Today, more than 20% of the world's population suffers from hypertension, a major risk factor for heart disease. Therefore, lifestyle modifications such as dietary change, smoking cessation, and exercise are often prescribed to hypertensive patients as a first-line treatment. This study aims to examine and compare the effects of different exercise regimens on the cardiovascular system, particularly that of high-intensity interval training (HIIT) and lower-to-moderate-intensity aerobic exercise (aka aerobic exercise). After researching various databases and extracting 4,724 studies, 196 were viable within the exclusion criteria related to exercise's effects on blood pressure and maximal oxygen uptake (V̇O2max). Of these, 36 studies were selected as viable, and their data is herein outlined. In addition, the results provided by these studies were summarized, respectively, and the raw data were analyzed using a two-tailed unpaired t-test. Through this study, we aim to clarify whether HIIT or lower-to-moderate-intensity aerobic exercise differ in their effects on improving cardiovascular health.It was observed that HIIT was non-inferior to lower-to-moderate-intensity aerobic exercise in the reduction of ambulatory blood pressure of hypertensive or normotensive individuals. However, HIIT was more effective at increasing cardiorespiratory fitness by means of V̇O2max than aerobic exercise was. Considering the significant time-to-completion difference between both exercise modalities, it is remarkable that HIIT has the same benefits as lower-to-moderate-intensity aerobic exercise on blood pressure and higher efficiency in increasing V̇O2max.

Polyethylene encasement (PE) film has been utilized to effectively control external corrosion of iron pipe for over 70 years. During those years, various associated technological advancements have been made in polymer science and corrosion control, including inhibitors and biological sciences as related to microbiologically influenced corrosion (MIC). This paper gives a brief history of PE film as a method of corrosion protection and describes how adoption of these advancements has led to the development of an enhanced PE film, designed to control MIC and initial corrosion reactions. Additional complimentary corrosion control measures, that are considered here, are metalized zinc external coatings and cathodic protection used in conjunction with PE encasement. Case histories and field-based corrosion testing, in what is described as a uniquely severe corrosive soil environment found in the United States, are summarized.

Basal cell carcinoma (BCC) is generally uncovered in sun-exposed areas, secondary to chronic unprotected UV exposure. The most common sites for nodular basal cells are the face, especially the nose, cheeks, forehead, nasolabial folds, and eyelids, with a history of crusting and friability. The commencement of BCC is 10 to 15 years from epidermal damage.Here, we report the case of a 52-year-old Caucasian female who presented to her primary care with an enlarging bump on the scalp for the past five years, which became tender and friable two months before the visit. The patient was clinically diagnosed with a solitary cyst and was referred for surgical excision. The pathology of the excised specimen revealed it to be a BCC.

Ulcerative colitis (UC) is an inflammatory bowel disease and causes inflammation and ulcer of the colon. Vedolizumab is a newer biological agent with an inhibitory effect on α4β7 integrin approved for moderate to severe UC patients. Our study reviewed the clinical response, clinical remission, and mucosal healing of vedolizumab in moderate to severe UC management. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a literature search in PubMed, Google Scholar, and Science Direct, and nine studies were included in the systematic review. At week six, vedolizumab showed a significant clinical response. At week 52, vedolizumab showed significant mucosal healing and clinical remission. The most commonly associated adverse effects are nasopharyngitis, oropharyngeal infection, and gastrointestinal infection. However, additional clinical trials and observational studies with longer follow-ups are required to study the efficacy and safety of the drug.

Pancreatic cancer is one of the common cancers globally, with a poor survival outcome. Metformin, a popular anti-diabetic drug, has gained popularity for its use in the chemoprevention of cancer. However, results regarding the survival benefit of metformin in pancreatic cancer have been unpredictable. In this review, we aim to analyze the use of metformin in pancreatic cancer patients with pre-existing diabetes mellitus for survival benefit. We systematically conducted a literature search in PubMed, Science Direct, and Scopus databases to collect the relevant articles and reviewed them. Eventually, 11 quality appraised articles were included accessing overall survival as the primary outcome. Our results concluded that metformin can efficaciously improve survival in pancreatic cancer patients with coexisting diabetes mellitus, but the results are still incongruent. Hence, further prospective studies and clinical trials are essential to provide a strong evidence-based recommendation that will help prolong the lifespan of patients.

Highly accelerated life test (HALT) has been a common term in reliability for the past decade although it is widely misunderstood by many. HALT is based on a simple concept that a chain is only as strong as its weakest link. An electronic system is a complex chain of interacting components and assemblies. Many times a weakness found in HALT cannot be easily proven to be a future risk to reliability of the product. Many companies using HALT for the first time have dismissed a weakness found in HALT and only to discover it later as a significant contributor to field failures. Yet after HALT and highly accelerated stress screening (HASS) have been applied for new product development and the benefits of HALT have been observed first hand, the adoption of HALT methods typically becomes the main focus of a company's reliability development efforts.
