Herpes simplex esophagitis (HSE) is a viral infection of the esophagus caused by the herpes simplex virus (HSV), most commonly HSV-1. It predominantly presents among immunosuppressed individuals. Eosinophilic esophagitis (EoE) is a chronic, inflammatory, immune-mediated disease characterized by significant eosinophilic infiltration in the esophageal mucosa. It is often associated with atopic diseases, including asthma, food allergies, and eczema. Coexistence of HSE and EoE is rare and may be underdiagnosed due to challenges in diagnosing both conditions simultaneously. A major diagnostic dilemma can be traced to their histopathological similarities and differences. HSE is typically characterized by multinuclear giant cells containing intranuclear inclusions, while EoE involves eosinophilic infiltration in the esophageal epithelium. This report highlights the rare but remarkable coexistence between HSE and EoE secondary to a unique patient case. Although each condition may cause esophagitis individually, together—particularly in immunocompetent individuals—they do present a different diagnostic and therapeutic challenge.

Sepsis is a major cause of disease worldwide. Mobile applications (apps) have been developed to assist clinical practice. Current evidence evaluating such apps is diverse. This scoping review aimed to map currently available literature investigating the usage of mobile apps for sepsis-related healthcare. This will highlight evidence gaps, and areas for future innovation and app development.
Databases MEDLINE, Embase, CINAHL, Cochrane, Scopus, and Web of Science were searched in June 2023 (updated in July 2024). Studies containing original research investigating mobile apps for sepsis-related healthcare were included and analysed in three categories identified from the primary purpose of the app: (1) education and awareness, (2) clinical assistance, and (3) biomarker or pathogen detection.
A total of 1,755 studies were identified and 27 included following screening, of which 19 (70%) were published in 2020 or later. Most of the 27 studies investigated apps for clinical assistance (70%, n = 19). These apps were diverse, acting as digital solutions for data collection (n = 2), triage (n = 6), clinical guideline access (n = 5), alert delivery (n = 1), and outcome prediction (n = 5). There were five apps (19%) used to assist biomarker or pathogen detection. Of these, most (80%, n = 4) mobile apps were used to detect and quantify colorimetric signals in combination with assays, and all five apps had attachments necessary for laboratory processes. Lastly, three apps (11%) were designed to enhance education and awareness, two targeting medical education and one targeting public awareness.
Mobile applications offer innovative and exciting digital solutions for biomarker detection, education, and clinical support in sepsis-related healthcare. Current literature is highly heterogenous and rapidly developing.

Malabar chestnut seed from Nigeria is an underutilized seed in Africa that possesses different nutritional, functional, and medicinal characteristics. Nevertheless, there is no quality information on the antioxidant properties of the embryo, the whole seed, and the seed coat of the Pachira glabra. This research investigated the nutritional composition and antioxidant properties of the Malabar chestnut embryo (MCE), whole Malabar chestnut (WMC), and Malabar chestnut seed coat (MCSC).
The nuts were sorted, and the seed coat was separated from the embryo. This was processed to get the WMC, MCE, and MCSC flours, and they were analyzed for proximate composition, minerals, amino acid profiles, antinutrients, and antioxidant properties.
The proximate composition (g/100 g) showed high protein and fat content, total ash (2.50–3.50), crude fiber (2.04–11.43), moisture (3.62–7.93), and carbohydrate (13.29–37.92). The results also showed higher deposition of minerals in the seed coat, with phosphorus (2.82–5.26) and potassium (2.77–4.90) being the most abundant. This indicates that the seed can be used as a supplement for these nutrients. Low lead content was recorded in all samples. The antinutritional compositions were relatively lower in the embryo compared to the seed coat and whole seed. Furthermore, the high ratio of essential amino acids to non-essential amino acids (0.63–0.87), particularly in MCE, positions the seed as a potential high-quality protein source. The antioxidant properties demonstrated a high scavenging power, with a viable level of total phenol (198.65–330.41) mg GAE/g, total flavonoid (30.74–86.49) mg QE/g, as well as ABTS (2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)) and DPPH (2,2-diphenyl-1-picrylhydrazyl).
The seed coat and the embryo of the Malabar chestnut showed superior nutritional composition and antioxidant properties; therefore, they can be used for medicinal purposes and as an antioxidant in the management of chronic diet-based diseases.

Glioblastoma (GBM) is a complex condition with a poorly understood pathophysiology and no effective treatment to date. The present article highlights the role of canonical and non-canonical signal transducer and activator of transcription 3 (STAT3) interactions with nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) in the modulation of the mitochondrial melatonergic pathway in GBM microenvironment pathophysiology. The capacity of STAT3 and NF-κB to interact to upregulate the mitochondrial melatonergic pathway is suppressed systemically over the course of aging, thereby attenuating the capacity to achieve inflammation resolution. The suppressed capacity to induce the mitochondrial melatonergic pathway systemically is partly driven by the dramatic 10-fold decrease in pineal melatonin over aging. The attenuation of pineal melatonin in the first half of sleep over aging and aging-accelerating conditions disinhibits the effects of cortisol in the second half of sleep. This decrease in the melatonin/cortisol ratio alters the nature of night-time dampening and resetting in preparation for the coming day by altering cellular and intercellular homeostatic interactions. Aging and aging-accelerating conditions, by impacting the night-time melatonin/cortisol ratio, also suppress the capacity of the vagal nerve to resolve inflammation. This further contributes to systemic changes that influence GBM pathoetiology and ongoing pathophysiology. Aging-associated changes in night-time dampening and resetting provide a novel framework on which many previously disparate bodies of data on GBM pathophysiology can be collated. This has numerous future research, prevention, and treatment implications.

For decades, vaccines have been a key tool against microbial infections. However, the high cost of production and purification renders vaccines largely inaccessible to many developing countries. The limitations of conventional vaccines can be overcome by edible vaccines. To produce an oral vaccine, favourable vectors, such as plants and probiotics, are used. Recent studies have revealed the immunomodulatory effects of probiotics. To improve the efficacy of these vaccines, several adjuvant approaches have been employed. Postbiotics can be used as promising therapy for preventing infections and enhancing the host immune system due to their unique biochemical and microbial-derived properties. In this review, we discuss the feasibility of postbiotics as adjuvants for oral vaccines, highlighting their mechanisms of action, safety profile, and potential to enhance both mucosal and systemic immune responses.

Nurses perform many daily care tasks that expose them to work-related musculoskeletal disorders (WMSDs). Many studies have reported a high prevalence worldwide. Analyses by continent have provided a better understanding of the WMSD occurrence, but none have yet been conducted among African nurses. The aim was to conduct a systematic review analysis with meta-analysis of the overall WMSD prevalence and the prevalence by body area among nurses in Africa.
The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) method was used to present the results in the form of a systematic review analysis with meta-analysis. PubMed/Medline, ScienceDirect, Google Scholar, Mendeley, and Science.gov were explored between August 20 and 29, 2025 to identify studies that investigated the overall and body area WMSD prevalence among African nurses of any specialty without a date limit. Studies were included if they were cross sectional survey assessing the WMSD prevalence among nurses of any specialty or department working in Africa. Any study that was not a peer-reviewed cross-sectional survey published in English, that did not involve African nurses, or that did not report, or sufficiently detail data on the prevalence was excluded. The quality of each article included was assessed using the cross-sectional study assessment tool (AXIS). A meta-analysis with quantification of heterogeneity (Cochran’s Q test and I2 statistic) was conducted. Based on these parameters, a fixed or random effects model was selected to estimate the prevalence. Forest plots were used to summarize the overall, neck, upper back, lower back, shoulder, elbow, wrist, hip, knee, and ankle WMSD prevalence.
Nineteen cross-sectional studies were selected from the 4,305 identified studies, involving 4,670 African nurses from 10 countries. A significant heterogeneity was highlighted between studies (Cochran’s Q test and I2 statistic). Lower back [59.5%, 95% confidence interval (CI): 52.8–66.2%, 4,670 participants], neck (35.4%, 95% CI: 28.0–42.8%, 4,670 participants), and knee (34.4%, 95% CI: 27.2–41.6%, 4,601 participants) were the most exposed areas. The overall WMSD prevalence was pooled at 74.6% (95% CI: 67.0−82.3%, 4,266 nurses).
Comparison of these results with the literature showed that African nurses were less affected than those on other continents. However, the data were highly heterogeneous. Due to the numerous risk factors associated with nursing work, it is necessary to continue research projects and educational activities, as well as the development of health policies aimed at improving quality of life at work, specifically by expanding the investigation using subgroup analysis.

Polycystic ovary syndrome (PCOS) is a common endocrine–metabolic condition that carries a higher cardiovascular risk than currently reflected by traditional screening tools. Emerging evidence suggests that resting tachycardia and autonomic dysfunction may serve as early, non-invasive indicators of cardiovascular dysregulation in this population. This review synthesizes current data on resting heart rate (RHR), heart rate variability (HRV), and direct autonomic markers in women with PCOS, drawing from human studies published between 2000 and 2025. Across 32 eligible studies, most reported increased sympathetic activity, reduced parasympathetic tone, elevated RHR, and impaired HRV patterns observed even in normal-weight or metabolically mild PCOS phenotypes. These alterations correlate with endothelial dysfunction, arterial stiffness, and subclinical atherosclerosis, underscoring their cardiovascular relevance. Mechanistic insights highlight the contributions of insulin resistance, hyperandrogenism, inflammation, adipokine imbalance, chemoreflex sensitization, and altered cortisol metabolism to autonomic disruption. Despite consistent findings, methodological variability in HRV protocols and inadequate adjustment for major confounders limit definitive interpretation. RHR, due to its simplicity and accessibility, including through wearable devices, holds promise as a supportive early risk signal; however, it should not be used in isolation. Future studies must adopt standardized autonomic measurements, including diverse cohorts, and evaluate whether modifying autonomic markers translates into improved cardiometabolic outcomes. Integrating RHR and HRV with metabolic and endocrine markers may enhance early cardiovascular risk stratification in women with PCOS.

The Gerbode defect is characterized by a high ventricular septal defect associated with a defect in the septal leaflet of the tricuspid valve, allowing blood to enter the right atrium from the left ventricle. It accounts for approximately 0.08% of intracardiac shunts and may be congenital or acquired. We describe a rare case of Gerbode defect secondary to tricuspid valve endocarditis. A 58-year-old male patient presented with acute infective endocarditis due to Staphylococcus aureus, related to central venous access. Echocardiography showed a tricuspid valve with thickened leaflets and a small mobile image on the atrial side of the septal leaflet, as well as moderate to severe regurgitation. After completion of the antibiotic regimen with resolution of the infectious condition, the patient was discharged asymptomatic, and a new echocardiogram showed no vegetation on the tricuspid valve. During outpatient follow-up, he presented dyspnea on mild exertion, and consecutive echocardiograms showed moderate tricuspid insufficiency and significant pulmonary hypertension with a pulmonary artery systolic pressure of 83 mmHg (reference: 30 mmHg). He underwent right and left cardiac catheterization, which showed a Gerbode defect, and a transesophageal echocardiogram showed a shunt in the subaortic region measuring 6 to 8 mm, with a maximum gradient of 56 mmHg. He underwent elective surgery to correct the Gerbode defect and tricuspid valve repair, with a good clinical result. The Gerbode defect is rare, and the diagnosis can be challenging because it simulates other conditions. Treatment consists of closing the defect when it generates refractory symptoms or complications. The reported case was surgically corrected, with a good result and favorable evolution.

Hypertriglyceridemia is linked to increased risk of diabetes diagnosis, incidence, and mortality. However, whether individuals with normal triglyceride levels (i.e., < 1.7 mmol/L) uniformly exhibit low diabetes risk remains underexplored. Specifically, it is unclear whether triglyceride levels within the normal range are associated with plasma glucose levels and the prevalence of type 2 diabetes (T2DM). This study aimed to address these gaps by examining the associations between triglyceride levels and fasting plasma glucose, as well as between triglyceride levels and T2DM, in individuals with triglycerides in the normal range.
This cross-sectional study included 16,706 Chinese adults with triglyceride levels below 1.7 mmol/L. Among them, 1,067 had T2DM. Associations between triglyceride levels and fasting plasma glucose were assessed using linear regression, while associations with T2DM were evaluated using binary logistic regression. The optimal triglyceride cut-off for T2DM diagnosis was determined via receiver operating characteristic (ROC) curve analysis.
Triglyceride levels were positively associated with fasting plasma glucose after multivariate adjustment (β = 0.034, P < 0.001). A one-unit increase in the natural log of triglyceride levels was associated with a 61% higher adjusted odds of T2DM [odds ratio (OR), 1.61; 95% confidence interval (CI), 1.19–2.17; P = 0.002]. The optimal triglyceride cut-off for T2DM diagnosis was 1.09 mmol/L. Participants with triglyceride levels ≥ 1.09 mmol/L had a 28% higher odds of T2DM (OR, 1.28; 95% CI, 1.07–1.53; P = 0.006) compared to those with levels below the cut-off.
Among individuals with normal triglyceride levels, higher triglyceride concentrations were associated with higher odds of T2DM diagnosis, with an optimal diagnostic cut-off of 1.09 mmol/L. These findings suggest that adults with triglyceride levels more than 1.09 mmol/L may benefit from closer monitoring for T2DM development.

The emergence of stem-cell-derived enamel organoids and dentin-producing dental pulp stem cell constructs presents new possibilities for restoring carious lesions using autologous enamel–dentin inlays. This overview outlines the biological and technological advances supporting this approach and proposes a workflow oriented toward clinical application. The benefits of tissue-based inlays, including inherent biomechanical compatibility, aesthetic accuracy, and potential for biological integration, are contrasted with those of purely artificial materials. Significant regenerative developments include the formation of human enamel organoids and odontoblast-lineage cells in vitro, 3D bioprinting of tooth-shaped constructs with demineralised dentin matrix and poly(ε‑caprolactone) scaffolds, and fibre-guiding periodontal ligament scaffolds that restore Sharpey’s fibres in vivo. The mechanical performance of adhesive resin cements, with bond strengths of approximately 4–7 MPa to enamel and dentin, and their durability in reattaching natural tooth fragments, supports the feasibility of bonding biological inlays. Practical considerations include controlling the slow degradation and hydrophobicity of poly(ε-caprolactone) through the use of ceramic or natural polymer additives, employing multi-material 3D printing to co-print mineralized enamel and cell-laden dentin layers, and achieving the desired shade, microstructure, and mechanical properties, exemplified by a compressive strength of approximately 677 MPa for 3D-printed zirconia crowns. Despite regulatory and translational challenges, the integration of digital dentistry, bioprinting, and stem cell science points toward future “grow and glue” restorations that may replace traditional drill-and-fill methods.

Heart failure (HF) is still one of the most common causes of death today. The vast majority of heart diseases end up leading to HF, which therefore has a high prevalence in the adult population (on average 1–2%), and which increases enormously (over 10%) after the age of 65, becoming the most frequent cause of hospitalization for these subjects. It is therefore necessary to increase efforts to deepen our understanding of the pathophysiological mechanisms that lead to HF and its worsening, particularly with regard to hormonal-metabolic derangements as contributors to HF development and progression. This, in the hope of being able, in the near future, to intervene on them, reducing the prevalence of this pathology and its economic impact on countries’ healthcare spending. To this aim, we performed a narrative review of the scientific literature on the interactions between both insulin and the growth hormone/insulin-like growth factor-1 axis and the cardiovascular system, and in particular, to verify the role that these hormones may play in the development and negative progression of HF.

The s-triazine scaffold has emerged as a privileged heterocyclic nucleus/moiety in pharmaceutical discovery and development, owing to its presence in several natural products and clinically relevant therapeutic agents, including enasidenib, gedatolisib, bimiralisib, atrazine, indaziflam, and triaziflam. s-Triazine derivatives are not only economically accessible and synthetically versatile, but they also exhibit a broad spectrum of noteworthy biological activities, encompassing anticancer, anti-inflammatory, antiviral, antidiabetic, anticonvulsant, antitubercular, and antimicrobial properties. Their widespread utility is further supported by the ease of synthesis from inexpensive precursors such as amidines or the readily available 2,4,6-trichloro-1,3,5-triazine (cyanuric chloride), which enables sequential functionalization and the rapid generation of diverse analogues. The heightened reactivity and modularity of the s-triazine core have facilitated the development of structurally rich heterocyclic hybrids with enhanced potency and improved pharmacological profiles. These multitarget-directed systems offer exciting opportunities for addressing various forms of cancer. Considering the increasing pace of innovation in this field, a comprehensive overview of recent advancements in s-triazine-based hybrid molecules is both timely and necessary. This review highlights current progress, key design strategies, and emerging perspectives to inspire continued efforts toward the identification of promising s-triazine-based lead candidates for future drug development as anticancer agents.

Multicenter imaging studies are increasingly critical in epidemiology, yet variability across scanners, acquisition protocols, and reconstruction algorithms introduces systematic biases that threaten reproducibility and comparability of quantitative biomarkers. This paper reviews the major sources of heterogeneity in MRI, CT, and PET-CT data, highlighting their impact on epidemiologic inference, including misclassification, reduced statistical power, and compromised generalizability. We outline harmonization strategies spanning pre-acquisition standardization, phantom-based calibration, post-acquisition intensity normalization, and advanced statistical and machine learning methods such as ComBat and domain adaptation. Illustrative examples from MRI flow quantification and radiomic feature extraction demonstrate how harmonization can mitigate site effects and enable robust large-scale analyses.

This study aimed to assess the effectiveness of mepolizumab in enhancing asthma control, achieving clinical remission, and alleviating upper airway symptoms in patients with severe eosinophilic asthma (SEA) with comorbid nasal polyps and/or chronic rhinosinusitis (CRS). Additionally, it aimed to identify clinical and laboratory predictors of remission. The findings are based on real-world data from a single center.
This retrospective, single-center, real-world study included 99 patients diagnosed with SEA. Patients were categorized into three groups based on the presence or absence of nasal polyps and CRS. Treatment response was evaluated using the asthma control test (ACT), spirometry, laboratory biomarkers, computed tomography (CT) scores, and nasal polyp scores. Remission was defined as the absence of asthma exacerbations and systemic corticosteroid use, along with improvements in both forced expiratory volume in 1 second (FEV1) and ACT scores.
After 12 months of mepolizumab therapy, there were significant improvements in FEV1 values, asthma exacerbation frequency, systemic corticosteroid requirements, and nasal symptom scores. The overall remission rate was 30.6%. Patients with higher baseline FEV1 and no prior exposure to omalizumab were more likely to achieve remission.
This real-world evidence suggests that mepolizumab provides meaningful clinical, functional, and radiological improvements in patients with SEA, regardless of comorbid nasal polyps or CRS. Furthermore, the study highlights independent predictors associated with treatment-induced remission in this population.

Multiple sclerosis (MS) is a chronic inflammatory and neurodegenerative disease affecting the central nervous system, the cause of which remains unknown. Environmental, genetic, and immunological factors are considered risk factors. MS has no cure; therefore, therapy focuses on reducing the number of outbreaks, controlling symptoms, and therapies aimed at modifying the course of the disease. Innovative strategies that promote remyelination and repair of damaged brain tissue are under investigation. This review aims to compile and systematize the available knowledge on the multifactorial nature of MS, highlighting the main risk factors. It also discusses the mechanisms underlying the pathogenesis of the disease, current therapies, and prospects, presenting a comprehensive overview of the effect of various drugs on remyelination and repair of central nervous system damage.
A comprehensive literature search, guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards, was conducted across PubMed, Cochrane Library, Web of Science, and ClinicalTrials.gov to identify relevant clinical trials. Of the studies retrieved, 13 were selected for this review. These trials specifically explored integrated therapeutic approaches, combining pharmacological and non-pharmacological interventions, for managing MS.
The results reflect the multifactorial nature of MS and the existence of several promising therapies to combat inflammation and demyelination, as well as to promote remyelination. Reducing inflammation remains the main target, but new approaches such as clemastine, liothyronine, interleukin (IL)-2, N-acetylglucosamine, and intracranial transplantation of fetal human neural precursor cells have shown promising results.
Currently, the therapies available for MS target the peripheral immune system. Therefore, more studies are needed on treatment therapies that combine immunomodulation of the peripheral and central nervous systems to reduce the neurological disability of patients. It is also concluded that the therapies were safe and were well tolerated, given the occurrence of a small number of adverse events.

Mango kernel has potential as an alternative flour source to enhance the nutritional value of flatbreads, providing a cost-effective means of promoting healthier foods. This study aimed to determine the effects of mango kernel flour (MKF) incorporation on the physicochemical and sensory properties of balady flatbread.
Balady flatbreads were prepared with different substitution levels of MKF (0%, 25%, 50%, 75%, and 100%). The samples were analyzed for proximate composition, mineral content, color attributes, texture profile, specific volume, microstructure (via scanning electron microscopy), and sensory characteristics.
Chemical analysis revealed that MKF substitution significantly increased fat (3.74–13.35%), ash (1.51–2.13%), crude fiber (0.32–2.93%), and energy (266.65–328.78 kcal/g) contents, while protein content remained unaffected. In contrast, moisture (36.34–29.37%) and carbohydrate (54.75–47.98%) contents decreased significantly. Increasing MKF levels also elevated potassium, iron, and magnesium contents. The specific volume decreased (3.48–0.70 mL/g), and texture hardness increased markedly (184.67–9,373.42 g). Scanning electron microscopy showed a more compact structure (pore size reduced from 69.07 to 42.30 μm) with darker and less yellow coloration as MKF substitution increased. Sensory evaluation by 50 panelists indicated that the control sample (100% wheat flour) received significantly higher scores for all evaluated attributes.
Increasing levels of MKF incorporation enhanced fat, fiber, ash, and mineral contents but reduced loaf volume, increased hardness, decreased pore size, and lowered sensory acceptability. Among the formulations tested, flatbread containing 25% MKF (FB2) was identified as the optimal formulation, offering improved nutritional properties with acceptable sensory quality. These findings highlight the potential application of MKF as a sustainable, value-added ingredient for developing nutrient-enriched flatbreads and other bakery products, contributing to food waste reduction and functional food innovation.

Probiotic microorganisms, primarily lactic acid bacteria (LAB) and bifidobacteria, are able to solve most of the problems of animal by-products that hinder their use in the food industry. The most important property of LAB is their antagonistic activity against pathogenic and opportunistic microorganisms. The aim of the study is to compare the antimicrobial activity of microorganisms from commercial starters, medicinal preparations, and newly isolated strains. It is important to evaluate two alternative methods for determining antimicrobial activity in terms of their interchangeability.
A total of 11 microorganisms and consortia from various sources were studied, including five newly isolated strains. Their antagonistic activity against 8 strains of pathogenic and opportunistic microorganisms was evaluated by two in vitro methods: agar diffusion and co-cultivation. Their interchangeability was assessed using the linear Pearson correlation coefficient.
The 12th hour of cultivation, corresponding to the maximum specific growth rate of the studied newly isolated strains and consortia were determined and used to take a supernatant sample for co-cultivation with test pathogens. Of the studied cultures, lactobacilli and pediococci showed the greatest antagonistic activity against the tested pathogens, while Staphylococcus spp. showed minimal activity.
The highest inhibition index was observed in consortia containing Lactobacillus and Pediococcus. The antagonistic activity of the newly isolated strains is lower than that of meat starter cultures and medicinal products. The evaluation of the comparability of analytical methods for determining antimicrobial activity demonstrates a high positive correlation of the results, but requires further research to resolve the issue of their interchangeability.

Digestive diseases comprise a diverse range of illnesses, which are prevalent worldwide and represent an important health issue. This is particularly relevant for the impact of metabolic dysfunction-associated steatotic liver disease (MASLD) due to its close association with the obesity pandemic, contributing to the escalation of MASLD as the most common form of chronic liver disease, and the main cause of liver cancer. Not only does MASLD reflect the deterioration of liver health, but it also has far-reaching consequences for the development of extrahepatic digestive diseases. Along with the progression of liver and digestive diseases to liver, colorectal and pancreatic cancer, the onset of inflammation in diseases of the digestive tract, drug-induced liver injury, and cholestasis, drives and contributes to the rise of these diseases in the future, which merit the attention of clinical and translational research to increase our understanding of the pathogenic mechanisms underlying these disorders in order to improve the diagnosis, management, and treatment. With this goal in mind, the current collaborative review gathers experts in a wide range of liver and digestive diseases to provide an up-to-date overview of the mechanisms of disease and identify novel strategies for the improvement of these important health issues.

Neonatal jaundice or neonatal hyperbilirubinemia is a common medical condition impacting newborns and pathological jaundice if left untreated, leads to neurological encephalopathy and/or death. The majority of pathological jaundice cases occur in low and middle- income countries (LMIC). Phototherapy has been determined to be the safest and most effective treatment for jaundice. Although inexpensive light-emitting diodes are available on the market, commercial phototherapy devices are expensive (~US$2,000), which creates a barrier to access for these devices in LMIC. Efforts to construct cost-effective phototherapy units have been implemented in the past, but need a method to validate the intensity and wavelength of light received by the infant at a distance away from the source.
To enable low-cost phototherapy units to be used clinically, this study provides an open-source, low-cost, distributed manufacturing approach to create a light sensor to calibrate phototherapy units. This instrument is a necessary component of any open-source phototherapy treatment used in a clinical setting. This novel instrument was validated by comparing its irradiance and wavelength reading to the commercially calibrated Ocean Insight UV-VIS spectrometer under varying lighting conditions, including that of the existing Datex-Ohmeda Giraffe Spot PT Lite phototherapy equipment accessible through Victoria Children’s Hospital Neonatal Care Ward in London, Ontario, and Kiambu County Hospital in Kenya.
The results of this study have demonstrated that for under US$150, a phototherapy calibration device can be constructed capable of measuring up to 200 uW/cm2/nm with an accuracy of 98.6% and detect the peak wavelength within ±12.5 nm.
It can be concluded that 3D printed open-source irradiance meters are a viable option for calibrating phototherapy units in LMIC to treat hyperbilirubinemia.
