Medical research plays a vital role in advancing human knowledge, developing new therapies and procedures, and reducing human suffering. Following the atrocities committed in the name of medical research by German physicians during the Nazi era, the Nuremberg trials were held, and an ethical code was created to establish the limits within which medical research can operate. Consequently, legal regimes built upon this ethical foundation to develop laws that ensure the integrity of medical research and the safety of human subjects. These laws sought to protect human subjects by minimizing conflicts of interest that may arise during the process. Furthermore, conflicts of interest may be financial such as monetary gain, or nonfinancial such as promotion and career advancement. However, with a $1.1 billion median cost of developing a new drug, the focus of these laws was directed towards financial conflicts of interest. But should we expand these laws to include nonfinancial conflicts of interest? This Article highlights prominent arguments in favor of and against the regulation of nonfinancial conflicts of interest in medical research. It further concludes that adequate institutional policies--not additional regulations--strike the right balance between the need to safeguard against the harmful effects of nonfinancial conflicts of interest on the one hand and avoiding the drawbacks of overregulation on the other.

Planch. and (A. Chev.) C.F. Liang et A.R. Ferguson are the botanical names for the two main closely related kiwifruit species that are cultivated worldwide [1]. According to the Food and Agriculture Organisation (FAO) of the United Nation, kiwifruit is produced on 268,788 hectares of land worldwide, yielding 4,348,011 metric tonnes of fruit per year. China is the world's top producer, followed by Italy, New Zealand, Chile, and Greece, with a cumulative valuation of 2,907,580 thousand US dollars for export (http://www.fao.org/faostat/en/#data/QC). Several research using nutrient medium and other inorganic treatments on softwood cuttings for micro-propagation techniques have shown promising outcomes [2,3]. Several agricultural and horticultural crops have demonstrated significantly improved crop growth, quality, and reproduction when treated with seaweed extracts [4]. It is possible to utilise seaweed extracts to encourage cuttings from perennial fruit species, such as kiwifruit (), to root and flourish. Absence of a growth regulator permitted by organic methods is one of the main obstacles in kiwifruit production. Hardwood cuttings are the most popular technique of clonally reproducing kiwifruit, and the cuttings' ability to root depends on the application of synthetic auxins, which is not allowed in organic agriculture. Therefore, alternative biostimulants have been used to promote the rooting of kiwifruit cuttings in this study. For six hours, the cuttings in this investigation were submerged in base dipping solutions containing 1, 5, 10, and 50 % of G Sap (), K Sap (), AN (), EM (), HA (Humic acid), and control (water). After that, for a period of six months, the treatments of G Sap, K Sap, AN, EM, HA, and control were applied (at the rate of 50 ml of solutions) to the potted cuttings at intervals of fifteen days. The dataset provided the data of the rooting percent in all the kiwifruit cultivars, namely 'Monty', 'Abott', 'Hayward', 'Allison' and 'Bruno' ( ≤ 0.01), shoot and root growth parameters including leaf number per cutting, number of roots per cutting, number of branches, plant height, shoot diameter, root length, root diameter and root weight with the application of seaweed extracts. Also data of pigments (chlorophyll , chlorophyll and total carotenoids), metabolites (total carbohydrates and soluble phenols) and electrolyte leakage were collected after the treatments. Data of four root promoting candidate genes ( and ) were also described which indicated the influence of the biostimulants on the cuttings. The application of seaweed extracts resulted in a positive increase in all shoot and root growth parameters, including the number of leaves per cutting, the number of roots per cutting, the number of branches, plant height, shoot diameter, root length, root diameter, and root weight ( ≤ 0.05). In comparison to the control cuttings, the seaweed extract-treated cuttings showed significantly greater levels of pigments (such as chlorophyll a, chlorophyll b, and total carotenoids), metabolites (such as total carbohydrates and soluble phenols), and reduced electrolyte leakage. Various treatments (1, 5 and 10% solutions of G Sap, K Sap, AN, EM, HA and control) gave positive impact on nutrient parameters of kiwifruit cultivar 'Hayward'. Moreover, the relative positive expressions of root inducing genes ( and ) was observed in leaves and roots of cultivar 'Hayward' by qRT-PCR after treatment with G Sap, K Sap, AN, EM, HA @ 10 % and control. Thus, it can be said that seaweed extract and humic acid are good substitutes for synthetic hormones in encouraging kiwifruit cuttings to root and flourish.

Evaluating the effect of diethyl ether and moringa oleifera antioxidant additives on the performance and emission characteristics of jatropha biodiesel-diesel blended fuel on CI engine - An experimental investigation.
Alternative fuels can be produced from both non-edible feedstocks and edible crops. The higher production costs and contaminating nature of vegetable biofuels, which cause engine component failure, make it conceivable to encourage the synthesis of biodiesel from non-edible sources. One of the most widely utilized alternative fuels is Jatropha biofuel, which has performance levels comparable to diesel fuels and can be used with CI (Compression Ignition) engines without any modifications. However when it comes to oxidative stability properties that impact shelf life and commercialization, the majority of biodiesels-including Jatropha-are lacking. Therefore, the objective of this study was to enhance the oxidative stability and other physicochemical parameters, such performance and emission characteristics, of Jatropha biodiesel with diesel blends by adding additives like DEE (diethyl ether) and MA (moringa oleifera antioxidant). The seeds of jatropha and moringa were harvested by hand and then mechanically extracted with a screw press. A conical flask containing the precisely weighed amount of oil is filled with 50 mL of neutral alcohol. The combination is then heated for an hour using a water condenser over a bath. Using phenolphthalein indicator, the contents are titrated with KOH solution after cooling. Weight of oil taken (w)/volume of KOH used (mL) × normality of KOH is the formula used to determine the acidity value of jatropha oil. It is therefore below the minimum level set by ASTM D 675, which is 2.5 mg KOH/g. Methanol was used in the transesterification process to produce biodiesel, and potassium hydroxide (KOH) was used as a catalyst. Then, using 5 % DEE and 10 % MA additives, the physicochemical properties of jatropha biodiesel-such as density, kinematics viscosity, calorific value, and oxidative stability-were characterized. The percentage of improvement of the biodiesel's mentioned properties with these additives was 0.68 %, 2.8 %, 0.73 %, and 33.8 %, respectively. The brake thermal efficiency (BTE) of B40MA10DEE05D45 increased by 8.52 % whereas the brake specific fuel consumption (BSFC) of B50MA10DEE05D35, which is Made up of 44 % diesel, 50 % jatropha biodiesel, 5 % DEE, and 10 % MA fuels, declined by 5.14 %. As a result of these additions, the blended fuel's CO, HC, and NOx emissions were reduced by 3.51 %, 2.25 %, and 8.64 %, respectively. Therefore, a 20 % blend of Jatropha biodiesel and diesel containing antioxidants from Moringa can be used in compression ignition engines without the need for engine modifications and with high oxidation stability.

The 5th edition of the World Health Organization (WHO) classification of haematolymphoid tumours used the hierarchical system to classify T-cell and NK-cell lymphoid proliferations and lymphomas (T/NK-LPD/LYM) based on research advances and clinicopathological characteristics of the diseases. In this edition of classification, tumour-like lesions were included, some tumors were added/deleted, the names or terms of certain diseases were refined, and the diagnostic criteria or subtypes of some diseases were revised. This group of diseases was reintegrated from non-clonal hyperplasia to highly aggressive lymphoma, which would further reflect the nature of T/NK-LPD/LYM and benefit to clinical application.

Consuming enough energy to meet high energy demands can be challenging for military personnel wherein logistical constraints limit food availability. Increasing dietary energy density (ED) and/or volume density (VD) of rations may be countermeasures, but whether positive linear associations between ED and energy intake (EI) hold at moderate-to-high ED and VD is unclear. This study examined the effects of covertly increasing the ED and VD of moderate ED (≥1.6 kcal/g) foods on appetite and energy intake. Twenty healthy men completed four 2-day treatments in random order by consuming a standardized diet containing three experimental food items (EXP) engineered using leavening, physical compression and fat manipulation to be isovolumetric but lower (L) or higher (H) in ED and VD creating four treatments: LED/LVD, LED/HVD, HED/LVD, HED/HVD. Consumption of EXP was compulsory during two meals and a snack, but remaining intake was self-selected (SSF). Results failed to show any ED-by-VD interactions. During LVD, EI was lower for EXP (-417 kcal [95%CI: 432, -402], p < 0.01) and TOTAL (SSF + EXP) (-276 kcal [95%CI: 470, -83], p = 0.01) compared to HVD, while SSF EI did not differ (140 kcal [-51, 332], p = 0.15). During LED, EI for EXP (-291 kcal [95%CI: 306, -276], p < 0.01) was lower than HED, while SSF EI was higher than HED (203 kcal 95%CI: [12, 394], p = 0.04) and TOTAL EI did not differ (-88 kcal [-282, 105], p = 0.36). Thus, when a small isovolumetric portion of the diet was manipulated, increasing the VD of moderate ED foods failed to elicit compensatory reductions in ad libitum EI while increasing the ED of moderate ED foods did. Findings may support VD manipulation of moderate ED foods as a strategy to promote increased short-term EI in environments wherein logistical burden may limit food volume.

Accuracy, potential, and limitations of probabilistic record linkage in identifying deaths by gender identity and sexual orientation in the state of Rio De Janeiro, Brazil.
BACKGROUND
Globally, the counting of deaths based on gender identity and sexual orientation has been a challenge for health systems. In most cases, non-governmental organizations have dedicated themselves to this work. Despite these efforts in generating information, the scarcity of official data presents significant limitations in policy formulation and actions guided by population needs. Therefore, this manuscript aims to evaluate the accuracy, potential, and limits of probabilistic data relationships to yield information on deaths according to gender identity and sexual orientation in the State of Rio de Janeiro.
METHODS
This study evaluated the accuracy of the probabilistic record linkage to obtain information on deaths according to gender and sexual orientation. Data from two information systems were used from June 15, 2015 to December 31, 2020. We constructed nine probabilistic data relationship strategies and identified the performance and cutoff points of the best strategy.
RESULTS
The best data blocking strategy was established through logical blocks with the first and last names, birthdate, and mother's name in the pairing strategy. With a population base of 80,178 records, 1556 deaths were retrieved. With an area under the curve of 0.979, this strategy presented 93.26% accuracy, 98.46% sensitivity, and 90.04% specificity for the cutoff point ≥ 17.9 of the data relationship score. The adoption of the cutoff point optimized the manual review phase, identifying 2259 (90.04%) of the 2509 false pairs and identifying 1532 (98.46%) of the 1556 true pairs.
CONCLUSION
With the identification of possible strategies for determining probabilistic data relationships, the retrieval of information on mortality according to sexual and gender markers has become feasible. Based on information from the daily routine of health services, the formulation of public policies that consider the LGBTQ + population more closely reflects the reality experienced by these population groups.

OBJECTIVE
To assess the panel composition of the 2 most important guideline developers in urology as equity and acceptability, important domains in clinical guideline development, require broad stakeholder representation.
METHODS
Following a predefined protocol, we identified all current AUA and EAU guideline documents. Two authors independently abstracted data including guideline topic, number and roles of panel members, voting status, and academic rank. We determined panel member's gender (woman, man, or nonbinary) and racialization (White or non-White) status based on name, internet picture, pronouns used, bios available, and gender listed on their profile.
RESULTS
We identified 31 AUA and 20 EAU guidelines for inclusion. Median panel size was 19 (interquartile range [IQR]: 17; 21) with 12 (IQR: 10; 14) voting members. The average composition of voting panels was predominantly male (81.8%) and White (86.8%). Eleven guideline panels (21.6%) did not include any women, and 9 (17.6%) panels had no representation of individuals from non-White groups. While gender distribution was similar among guidelines of the 2 organizations, the AUA included more voting members from non-White groups (14.3% vs 8.0%; P = .010). Analysis of the AUA panel composition over time revealed stable proportions of female and non-White individuals.
CONCLUSION
Both AUA and EAU guidelines exhibit insufficient representation of females and non-White individuals, with no evident improvement observed over time. Implementing more transparent processes that advocate for diverse panel representation may enhance the incorporation of stakeholder values and preferences, thereby improving the dissemination and adoption of guidelines.

BACKGROUND
Efficient data exchange and health care interoperability are impeded by medical records often being in nonstandardized or unstructured natural language format. Advanced language models, such as large language models (LLMs), may help overcome current challenges in information exchange.
OBJECTIVE
This study aims to evaluate the capability of LLMs in transforming and transferring health care data to support interoperability.
METHODS
Using data from the Medical Information Mart for Intensive Care III and UK Biobank, the study conducted 3 experiments. Experiment 1 assessed the accuracy of transforming structured laboratory results into unstructured format. Experiment 2 explored the conversion of diagnostic codes between the coding frameworks of the ICD-9-CM (International Classification of Diseases, Ninth Revision, Clinical Modification), and Systematized Nomenclature of Medicine Clinical Terms (SNOMED-CT) using a traditional mapping table and a text-based approach facilitated by the LLM ChatGPT. Experiment 3 focused on extracting targeted information from unstructured records that included comprehensive clinical information (discharge notes).
RESULTS
The text-based approach showed a high conversion accuracy in transforming laboratory results (experiment 1) and an enhanced consistency in diagnostic code conversion, particularly for frequently used diagnostic names, compared with the traditional mapping approach (experiment 2). In experiment 3, the LLM showed a positive predictive value of 87.2% in extracting generic drug names.
CONCLUSIONS
This study highlighted the potential role of LLMs in significantly improving health care data interoperability, demonstrated by their high accuracy and efficiency in data transformation and exchange. The LLMs hold vast potential for enhancing medical data exchange without complex standardization for medical terms and data structure.

The Retraction Watch Database (RWDB) is widely used to retrieve retraction data. However, its lack of affiliation normalization hinders the retrieval efficiency of retraction data for specific research-performing organizations. A query for a university name in the RWDB may yield retraction data entries for other universities with similar names, giving rise to the issue of affiliation naming proximity. This study assessed the impact of this issue on the retrieval efficiency of retraction records for 2,692 Chinese university names in English. The analysis revealed that the retrieval efficiency of retraction records for 206 Chinese university names can be influenced by 408 university names. As of 2022, the retrieval efficiency of retraction records for 96 Chinese university names was compromised by the involvement of 402 university names, resulting in an overall retraction inflation rate of 37.9% and an average rate of 45.0%. The findings highlight the importance of curating retraction data through affiliation-specific queries in the RWDB, adhering to the official English names of Chinese universities for scholarly publishing, and adopting the Research Organization Registry system for affiliation disambiguation. Given the significance of this issue concerning the English names of universities in non-English-speaking countries, the identified causes of the problem and proposed solutions can offer valuable insights for improving the retrieval of retraction records for non-Chinese universities in the RWDB.
