Abstract
A novel 12-step procedure was developed for preparing methyl 14-isocyano-3-methyltetradecanoate. “2+1B” tricarbonyl complexes [99mTc(CO)3(N^N)CN(CH2)11CH(CH3)CH2COOMe]+, where N^N = 2,2'-bipyridine (bipy) or 1,10-phenanthroline (phen), were prepared by the reaction of [99mTc(CO)3(N^N)(H2O,EtOH)]+ with methyl 14-isocyano-3-methyltetradecanoate in aqueous ethanol. The formation of technetium-99m complexes was confirmed by HPLC, and the partition coefficient (n-octanol/water) of these complexes was measured.
Scrambling power of soft photons
Authors: Su Xuan-Lin , Hamma Alioscia , Marcianò Antonino 
Published: October 2024

AbstractObservable scattering processes entail emission-absorption of soft photons. As these degrees of freedom go undetected, some information is lost. Whether some of this information can be recovered in the observation of the hard particles, depends of the actual pattern of the scrambling of information. We compute the information scrambling of electron and soft photon scattering by the tripartite mutual information in terms of the 2-Renyi entropy, and find a finite amount of scrambling is present. We show that scrambling is a byproduct of decoherence achieved by the scattering system in its interaction with the environment, due to the emission-absorption of soft photons in fully unitary processes.
Unraveling the Ethos of Literary Imagination in the Basātin al-ons of Akhsetān Dehlavi
Authors: Prakash Pranav 
Published: October 2024

Abstract
Basātin al-ons (The Gardens of Fondness, 1325–26) is the sole surviving work of an erudite courtier named Akhsetān Dehlavi (1301–51), who spent most of his adult life in the service of the sultan Gheyās al-Din Toghloq (r. 1320–24) and his son Mohammad b. Toghloq Shāh (r. 1324–51). This work exemplifies one of the earliest efforts by an Indian writer to interweave history, autobiography, eulogy, and folklore in the Persian genre of stylized prose (nasr). Against this backdrop, my essay examines the preface of the Basātin al-ons to elucidate the factors that motivated Akhsetān Dehlavi to narrate a collection of Hindavi tales in Persian prose.

Published: October 2024

Abstract
Background
Despite the ubiquity of adolescent screen use, there are limited longitudinal studies that examine the prospective relationships between screen time and child behavioral problems in a large, diverse nationwide sample of adolescents in the United States, which was the objective of the current study.

Methods
We analyzed cohort data of 9,538 adolescents (9–10 years at baseline in 2016–2018) with two years of follow-up from the Adolescent Brain Cognitive Development (ABCD) Study. We used mixed-effects models to analyze associations between baseline self-reported screen time and parent-reported mental health symptoms using the Child Behavior Checklist, with random effects adjusted for age, sex, race/ethnicity, household income, parent education, and study site. We tested for effect modification by sex and race/ethnicity.

Results
The sample was 48.8% female and racially/ethnically diverse (47.6% racial/ethnic minority). Higher total screen time was associated with all mental health symptoms in adjusted models, and the association was strongest for depressive (B = 0.10, 95% CI 0.06, 0.13, p < 0.001), conduct (B = 0.07, 95% CI 0.03, 0.10, p < 0.001), somatic (B = 0.06, 95% CI 0.01, 0.11, p = 0.026), and attention-deficit/hyperactivity symptoms (B = 0.06, 95% CI 0.01, 0.10, p = 0.013). The specific screen types with the greatest associations with depressive symptoms included video chat, texting, videos, and video games. The association between screen time and depressive, attention-deficit/hyperactivity, and oppositional defiant symptoms was stronger among White compared to Black adolescents. The association between screen time and depressive symptoms was stronger among White compared to Asian adolescents.

Conclusions
Screen time is prospectively associated with a range of mental health symptoms, especially depressive symptoms, though effect sizes are small. Video chat, texting, videos, and video games were the screen types with the greatest associations with depressive symptoms. Future research should examine potential mechanisms linking screen use with child behavior problems.
A landscape of resistance gene analogs in sour cherry (Prunus cerasus L.)
Authors: Wöhner Thomas Wolfgang , Emeriewen Ofere Francis 
Published: October 2024

Abstract
Objective
This research aims to analyze the presence and distribution of resistance genes in the avium and fruticosa subgenomes of Prunus cerasus through computational methods and bioinformatics tools.

Results
Analysis of genome and transcriptome sequencing data revealed a total of 19,570 transcripts with at least one resistance gene domain in Prunus cerasus subgenome avium and 19,142 in Prunus cerasus subgenome fruticosa. Key findings include the identification of 804 “complete” resistance gene transcripts in Prunus cerasus subgenome avium and 817 in Prunus cerasus subgenome fruticosa, with distinct distributions of resistance gene classes observed between the subgenomes. Phylogenetic analysis showed clustering of resistance genes, and unique resistance proteins were identified in each subgenome. Functional annotation comparisons with Arabidopsis thaliana highlighted shared and unique resistance genes, emphasizing the complexity of disease resistance in cherry species. Additionally, a higher diversity of RLKs and RLPs was observed, with 504 transcripts identified and 18 showing similarity to known reference genes.
An evaluation of the preprints produced at the beginning of the 2022 mpox public health emergency
Authors: Sterian Melanie , Samra Anmol , Pussegoda Kusala , Corrin Tricia , Qamar Mavra , Baumeister Austyn , Israr Izza , Waddell Lisa 
Published: October 2024

Abstract
Background
Preprints are scientific articles that have not undergone the peer-review process. They allow the latest evidence to be rapidly shared, however it is unclear whether they can be confidently used for decision-making during a public health emergency. This study aimed to compare the data and quality of preprints released during the first four months of the 2022 mpox outbreak to their published versions.

Methods
Eligible preprints (n = 76) posted between May to August 2022 were identified through an established mpox literature database and followed to July 2024 for changes in publication status. Quality of preprints and published studies was assessed by two independent reviewers to evaluate changes in quality, using validated tools that were available for the study design (n = 33). Tools included the Newcastle-Ottawa Scale; Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2); and JBI Critical Appraisal Checklists. The questions in each tool led to an overall quality assessment of high quality (no concerns with study design, conduct, and/or analysis), moderate quality (minor concerns) or low quality (several concerns). Changes in data (e.g. methods, outcomes, results) for preprint-published pairs (n = 60) were assessed by one reviewer and verified by a second.

Results
Preprints and published versions that could be evaluated for quality (n = 25 pairs) were mostly assessed as low quality. Minimal to no change in quality from preprint to published was identified: all observational studies (10/10), most case series (6/7) and all surveillance data analyses (3/3) had no change in overall quality, while some diagnostic test accuracy studies (3/5) improved or worsened their quality assessment scores. Among all pairs (n = 60), outcomes were often added in the published version (58%) and less commonly removed (18%). Numerical results changed from preprint to published in 53% of studies, however most of these studies (22/32) had changes that were minor and did not impact main conclusions of the study.

Conclusions
This study suggests the minimal changes in quality, results and main conclusions from preprint to published versions supports the use of preprints, and the use of the same critical evaluation tools on preprints as applied to published studies, in decision-making during a public health emergency.

Authors: Sultan Eman Anwar , Elweshahi Heba Mahmoud , Mohamed Fatma Tharwat , Ashry Mona 
Published: October 2024

Abstract
Background
Despite the global decline in HIV infections and mortality worldwide, the HIV epidemic is still growing in the MENA region. In the region, People Living with HIV (PLWH) are facing many challenges related to cultural values, norms, and provided services which create significant obstacles to HIV prevention and control efforts. This study aimed to translate, culturally adapt, and validate the “2021 Louisiana Needs Assessment Questionnaire” for use among Egyptians and Arabic-speaking population.

Methods
Arabic translation and cultural adaptation of the questionnaire passed through five stages. The questionnaire was translated forward and backward then an expert committee reviewed the translated version. Another expert committee reviewed the developed version after modification to assess the content validity using the Content Validity Index (CVI). The last step included a cognitive interview of a convenient sample of 50 adult PLWH in five consecutive rounds to assess subjects’ understanding of questions and response items and their meanings.

Results
Modifications were carried out all through the translation and adaptation process of the questionnaire including used words, nomenclature of services, adding or omitting response items, and ordering of questions and response items. The synthesized Arabic-adapted questionnaire has adequate content validity and all questions are clearly understood by the studied subjects. The calculated Content Validity Index of all questionnaire items ranged from 0.82 to 1.

Conclusion
The developed culturally adapted questionnaire has adequate content validity/semantic appropriateness. It can be used to assess the needs of PLWH in the MENA region with minor adaptations to fit each country. It can also be used to follow the outcome and impact of implemented programs and services. Further research is recommended to assess its psychometric properties.

AbstractThe use of enzymes in the production of food products is an ancient practice. Microbes provide several enzymes that are involved in improving the taste, texture, as well as aroma of food items, offering several benefits to the food industry. Subsequently, the ease of availability of these microbial enzymes has increased their utilization in the food industry. This cost-effectiveness and ease of commercial-scale production make enzymes ideal tools for various industrial uses. Microbial enzymes are utilized in processing food products such as those associated with the brewery, dairy and bakery industries. In addition, the nutritional value, color, aroma and texture of food products can be improved by using microbial enzymes. With the progress in technology, several novel enzymes in various applications of the food and beverages industry have been developed and demand is constantly increasing. The present review provides a comparative narrative of the applications of some of the predominating enzymes, such as phytases, lipases, lactases, pectinases, and laccases, commonly used as processing aids in the food industry.

The Effects of Non-functioning Adrenal Incidentalomas on Metabolic Comorbidities and Clinical Characteristics Changes: A Systematic Review and Meta-analysis. Context: Adrenal incidentalomas (AI) are frequently detected during abdominal imaging, with non-functioning adrenal incidentalomas (NFAI) being particularly common, even in elderly individuals. This meta-analysis investigates the influence of NFAI on metabolic comorbidities, comparing non-surgical and surgical patient groups, and assessing alterations in NFAI characteristics. Design: Our comprehensive meta-analysis utilized data from multiple databases, encompassing studies from January 2000 to August 21, 2023.Setting: Data sources included PubMed, Embase, Cochrane Library, and Web of Science. Participants: The analysis comprises 24 articles involving 2,770 NFAI patients, categorized into non-surgical and surgical groups. Intervention: The non-surgical group underwent no surgery, while the surgical group underwent tumor resection. Main Outcome Measure: The study investigated changes in metabolic comorbidities (hypertension, diabetes, obesity, lipid metabolism disorders), tumor characteristics, and hormone production in NFAI patients during follow-up or after surgery. Results: In the non-surgical NFAI patient group (20 studies), metabolic comorbidities exhibited a discernible upward trajectory during follow-up. The initial hypertension prevalence of 58.3% increased by 4.2% over a 4-5 year follow-up period. Moreover, diabetes, obesity, and lipid metabolism disorders experienced significant increases of 5.8%, 2.2%, and 8.8%, respectively. In contrast, the surgical group (6 studies) demonstrated a notable reduction in hypertension, with 43.9% of initially hypertensive patients achieving hypertension-free status after surgery. As for tumor changes in the non-surgical group, they were generally inconsequential, with only 5% of patients witnessing tumor growth exceeding 10mm over approximately 3.3 years, and 8% undergoing functional changes. These findings underscore the divergent impact of non-surgical and surgical interventions on metabolic comorbidities in NFAI patients. Conclusion: The study advocates for regular monitoring of blood glucose and blood pressure in NFAI patients, especially those with metabolic comorbidities. When necessary, adenoma resection should be considered. Further investigation is warranted to elucidate the mechanisms connecting NFAI with metabolic factors.

Abstract
Disclosure: N. Shahid: None. C. salgado: None. N. Gurtunca: None.
Background: Hypoglycemia in teenagers is seen less commonly than in younger children. Overweight children with prediabetes presenting with hypoglycemia symptoms are often considered to have reactive post-prandial hypoglycemia due to the degree of hyperinsulinemia with insulin resistance seen in these children. We present a 13-year-old boy with prediabetes, who presented with episodes of altered mental status and was found to have hypoglycemia due to a solitary insulin secreting tumor. Case presentation: A 13-yr old boy with pre-diabetes presented to the ER with altered consciousness and non-ketotic, non-acidotic hypoglycemia [25 mg/dl] & trace ketonuria in the setting of Influenza A infection. Weight and BMI above the 99th%ile and acanthosis nigricans in the skin creases. No access to oral hypoglycemic agents. Urine toxicology was negative. EEG was normal. Euglycemia and level of consciousness restored after IV dextrose & this was considered a possible hypoglycemic seizure episode secondary to poor oral intake. 4 months later he had another episode of altered mental status, jittery movements and was found to be hypoglycemic [41 mg/dl]. He was admitted for further workup of recurrent hypoglycemia. Adrenal insufficiency was ruled out and a diagnostic fast was started. After 15 hours, he developed non-ketotic hypoglycemia [&lt;50 mg/dl]. Critical sample [Table 1] and Glucagon challenge [Table 2] at the termination of the fast confirmed hyperinsulinemic hypoglycemia. Given the unusual age and presentation, an MRI abdomen was done which showed a 1.6 cm lesion in the pancreatic body [Fig 1]. Dotatate whole body PET scan confirmed the insulinoma with no evidence of nodal or distant metastasis [Fig 2]. He underwent surgical enucleation of the insulinoma. Intraoperative secretin showed no evidence of pancreatic duct dilatation or leakage. Hereditary endocrine tumor panel including multiple endocrine neoplasia [MEN] gene analysis was negative. The postoperative course was complicated by a persistent pancreatic leak and pancreatitis eventually requiring an ERCP and stent placement 2 months post operatively. Conclusion: Insulinomas are very rare neuroendocrine tumors in pediatric population, with a prevalence of one in 250,000 and median age at presentation of 45-50 years. About 90% insulinomas are benign and less than 10% are associated with MEN-1 syndrome. Chronic hypoglycemia irrespective of the underlying insulin resistance of prediabetes can be seen with insulinoma and can cause hypoglycemia unawareness as seen in our patient. This has also been reported in literature to be misdiagnosed as refractory epilepsy or psychiatric disorders. Hypoglycemic symptoms at any age should be promptly worked up. Ruling out associated neuroendocrine hereditary tumor syndromes is crucial and prognosis of benign solitary insulinomas after surgical removal is mostly favorable.

8070 Atypical New Onset Diabetes Mellitus in a Young Male: Is this LADA vs Type 1 or Type 2?
Authors: Devineni S K , Shaik S , Gilden J L 
Published: October 2024

Abstract
Disclosure: S.K. Devineni: None. S. Shaik: None. J.L. Gilden: None.
Background: Recent literature suggests that autoantibody seropositivity is common in new onset autoimmune Diabetes Mellitus (DM), especially in younger patients. Latent autoimmune diabetes of adults (LADA), a form of adult-onset autoimmune DM. is considered a mix of type 1 and type 2 DM, sharing similar immune cell characteristics to both subtypes. Unlike type 1, LADA patients do not require insulin for glycemic control for the first six months after diagnosis. Unlike type 2, LADA patients are positive for single islet autoantibody, glutamic acid decarboxylase (GAD), and anti-gliadin antibodies. Patients with LADA often present with symptoms (polyuria, polydipsia, nocturia, fatigue, and visual changes). We present a case of new onset Diabetes Mellitus in a young male, autoantibody seronegative, at the time of diagnosis. Case report: A 19-year-old Caucasian male was sent to the Emergency Department with a serum blood glucose (BG) level of 579 mg% after routine blood tests. He denied any clinical symptoms and serum levels showed no elevation in ketones, nor bicarbonate levels, ruling out ketoacidosis. His hemoglobin A1c at that time was 14.7%. He denied prior knowledge of personal or family history of DM. or other autoimmune disorders. However, it was discovered that routine labs done 1 ½ months earlier on a Health Screen revealed BG=295 mg% with urine positive for ketones (80 mg/dl) and glucose (&gt;1000 mg/dL). Physical Exam: (HT=178 cm; WT=79 Kg) was unremarkable. Autoantibodies for GAD 65, islet-cell, Zinc transporter 8, and Islet Antigen 2 were all negative. He was hospitalized for 9 days. BG levels were difficult to control and required increasing doses of both long acting and short acting insulin. He was discharged with insulin therapy (30 units of glargine at nighttime and 12 units of premeal aspart). One week later, the patient ate several gummy bears as a nighttime snack and subsequently woke up in the middle of the night feeling shaky and having blurry vision. BG was greater than 300 mg%. In the emergency room, he. received intravenous fluids. No insulin was given as his BG normalized and he was discharged. Later, a continuous glucose monitor revealed multiple hypoglycemic episodes. The patient was living in a situation where he only had limited access to certain foods, and thus his insulin regimen was decreased (28 units glargine and 10 units aspart for meals) Conclusion: We present the case of new onset atypical DM in a young patient whose insulin sensitivity and risk factors seem to resemble a pattern of type 1 DM; despite seronegative autoantibodies We predict that he may eventually seroconvert to type 1 DM. It is also possible that he may have an unusual presentation of LADA or type 2 DM, although he had no hyperglycemic symptoms.

5180 Atypical Presentation of Type 2 Diabetes Mellitus in a 72Year Old Caucasian Male with Hemoglobin J-Baltimore Variant: A Case Report
Authors: Muojieje Chukwudi , Luzuriaga Maria 
Published: October 2024

Abstract

Objective: This case report discusses the unusual manifestation of Type 2 Diabetes Mellitus (T2DM) in a 72-year-old Caucasian male possessing a rare Hemoglobin variant, Hemoglobin J-Baltimore. It emphasizes the importance of recognizing how hemoglobin variants can impact HbA1c measurements. Alternative markers, such as fructosamine and HbA1c measurement using turbidimetric inhibition immunoassay (TINIA), are discussed as potential tools for a more precise assessment of glycemic control. Furthermore, it accentuates the effectiveness of tailored treatment strategies in such cases. Methods: A 72-year-old Caucasian male with a history of T2DM was referred to an endocrinology clinic due to substantial discordance between the blood glucose (BG) values when self-monitoring and HbA1c. The patient was diagnosed with T2DM a decade ago due to fasting hyperglycemia. His HbA1c levels had remained within normal range. He exhibited signs of diabetic nephropathy with moderately increased albuminuria. He was never prescribed an oral hypoglycemic agent. He reported polyuria, weight loss, and fatigue, prompting him to monitor his BG at home twice daily, revealing readings &gt; 200 mg/dl. HbA1c measurement using high-performance liquid chromatography (HPLC) was 4.8%. His fasting plasma glucose was 190 mg/dl, and fructosamine levels were 292 umol/L (205 - 285 umol/L). An HbA1c level via TINIA was 6.4%. Hemoglobin electrophoresis unveiled the presence of Hemoglobin J-Baltimore. We started metformin, resulting in an improvement in HbA1c from 6.4% to 5.8%. Fructosamine levels improved from 292 umol/L to 210 umol/L. Fasting blood glucose remained &gt; 150 mg/dl. Dulaglutide was introduced. Follow-up analysis showed an improvement in FBS to &lt; 120 mg/dl. HbA1c remained unchanged at 5.9%. Conclusion: The significance of hemoglobin variants, exemplified by Hemoglobin J-Baltimore, cannot be overstated in the context of patients with T2DM, especially within populations where these variants are uncommon. This case underscores the need for a nuanced approach to glycemic control assessment in such individuals. The utilization of alternative markers, such as HbA1c values obtained through TINIA, emerges as a valuable strategy. The role of continuous glucose monitoring (CGM) is crucial, providing real-time and comprehensive data, which enhances the quality of care and contributes to more tailored and effective treatment strategies.
