Authors: Saddang Wahyuni , Abdullah Nusratuddin , Hamid Firdaus , Bte Ladju Rusdiana , Idris Irfan , Wahyuni Sitti , Sriwijaya Sriwijaya , Maidarti Mila 
Published: February 2025

Background
Endometriosis, a chronic gynecological disorder characterized by the ectopic growth of endometrial tissue, involves complex inflammatory and angiogenic mechanisms. MicroRNAs (miRNAs), particularly Let-7a-1 and Let-7f-1, have been identified as key regulators of these pathways, influencing the progression and symptoms of the disease.
Objectives
This review aims to explore the roles of miRNA Let-7a-1 and Let-7f-1 in the regulation of inflammatory and angiogenic pathways in endometriosis, highlighting their potential as biomarkers and therapeutic targets.
Materials and Methods
A comprehensive literature search was conducted using databases such as PubMed, Scopus, and Web of Science. Relevant studies published between 2000 and 2024 were included, focusing on the expression, function, and regulatory mechanisms of Let-7a-1 and Let-7f-1 in endometriosis. Key findings were synthesized to provide an updated understanding of their biological and clinical relevance.
Results
Evidence indicates that Let-7a-1 and Let-7f-1 play pivotal roles in modulating pro-inflammatory cytokines, angiogenic factors like VEGF, and cellular proliferation in endometriotic lesions. Dysregulated expression of these miRNAs is associated with enhanced inflammatory responses and aberrant angiogenesis, contributing to the persistence and progression of endometriosis. Furthermore, preclinical studies demonstrate that targeting Let-7 family miRNAs can mitigate these processes, suggesting their potential utility in therapeutic strategies.
Conclusion
Let-7a-1 and Let-7f-1 serve as critical modulators in the inflammatory and angiogenic pathways of endometriosis, offering insights into disease pathophysiology. Their roles as biomarkers and therapeutic targets warrant further investigation, paving the way for novel diagnostic and treatment approaches in endometriosis management.

Significance of the neutrophil-to-lymphocyte ratio and the platelet-to-lymphocyte ratio as prognostic predictors after liver transplantation
Authors: Pascale Marco Maria , Frongillo Francesco , Vasta Pierangelo , Massimiani Giuseppe , Nure Erida , Agnes Salvatore 
Published: February 2025

BACKGROUND
The use of biomarkers, such as the neutrophil-to-lymphocyte ratio (NLR) and the neutrophil-to-platelet ratio (NPR), has shown promise in evaluating early outcomes after medical, interventional, and surgical treatments. NLR has emerged as an indicator of systemic inflammation and physiological stress. NPR has emerged as a potential indicator of inflammation and thrombotic risk in the context of surgical and radiological procedures.
AIM
To analyze the correlation of NLR and NPR with the development of post-liver transplantation (LT) early complications after stratification for hepatocellular carcinoma diagnosis.
METHODS
Consecutive patients undergone LT between January 2019 and December 2023 were enrolled. Data regarding the concentration of hemoglobin and the differential leukocyte count on postoperative days (POD) 0, 1, 3, and 5 were collected.
RESULTS
The dataset included 161 consecutive patients undergone LT. Clavien-Dindo IV-V complications had a good correlation with NLR POD 1 (P = 0.05), NLR POD 3 (P < 0.001), NLR POD 7 (P < 0.001), NPR POD 3 (P < 0.001). In addition, the NPR ratio on POD 3 correlated with the onset of 30-day hemorrhage (P = 0.009). Finally, 30-day mortality had a significant association with the NLR POD 1 (P = 0.03) and with NLR POD 7 (P = 0.004), while NPR had a significant correlation with 30-day mortality in NPR POD 7 (P = 0.004).
CONCLUSION
The analysis of NLR and NPR are strictly correlated with Clavien-Dindo IV-V complications and 30-day post-LT death.

Authors: Dhand Roshan , Okumura Kenji , Nishida Seigo , Dhand Abhay 
Published: February 2025

BACKGROUND
The coronavirus disease 2019 (COVID-19) pandemic had a profound societal impact in the United States which was associated with a decrease in overall life expectancy and an increase in substance abuse and firearm injury. Our understanding of changes in mortality trends during the pandemic and its effect on organ availability for transplantation is limited.
AIM
To examine the trends of substance abuse and firearm injury fatalities during COVID-19 and a potential correlation with organ transplantation.
METHODS
Crude rates of population-based deaths among adults (18-75 years) from firearm injury and substance abuse from the period of 2014-2021 were obtained from centers of disease control wide-ranging online data for epidemiologic research database. Crude rates of causes of donor (18-75 years) deaths from 2014-2021 were obtained from the united network for organ sharing database.
RESULTS
Average annual percentage change (AAPC) deaths among the United States population were 16.4% from substance abuse and 3.4% from firearm injury. AAPC in cause of death among organ donors was 10.9% from drug intoxication and 2.1% from firearm injury. There was a significant (P < 0.001) and progressive increase in mortality from both causes during the pandemic (2020-2021) and significant correlation (P < 0.001) between population and donor causes of death. COVID-19 exacerbated trends in substance abuse and firearm mortality with a consequent increase in organ donation from donors who died from these two causes.
CONCLUSION
Identifying the socioeconomic and regional disparities associated with increase in deaths from substance abuse and firearms can help guide post-pandemic healthcare policies and mitigate their impact on organ transplantation.

Ação de reintegração de posse movida pela Companhia Hidroelétrica do São Francisco (CHESF), contra particular
Authors: Barbosa Heim Bruno 
Published: February 2025

A presente sentença foi prolatada em ação de reintegração de posse movida pela Companhia Hidroelétrica do São Francisco (CHESF), contra particular. O processo tem característica peculiar, pois a autora somou aos argumentos da defesa de sua suposta posse a necessidade de desocupação da área para segurança de barragens.
A decisão merece destaque pelo cuidado técnico com o direito possessório, em especial pela precisa delimitação do objeto da ação de reintegração de posse, afastando a possibilidade de manejo das ações possessórias em caso que seria tipicamente de desapropriação, o que afirma o legítimo direito dos possuidores de áreas urbanas.
Também merece destaque por estabelecer correlação adequada entre ação possessória e outros instrumentos de planejamento territorial. Em primeiro lugar, reconhece que a definição de “área de segurança de barragem” não altera a condição de posse de autor e réu, sendo irrelevante para a resolução da pretensão possessória. Em segundo momento, socorre-se do Plano Diretor e do zoneamento incidente sobre a área, ZEIS, para afirmar que o local é passível de “ocupação e desenvolvimento de atividades urbanas”.
A defesa do réu foi realizada pelo advogado e professor Bruno Barbosa Heim, membro do Instituto Brasileiro de Direito Urbanístico (IBDU).
Desejamos que, tal como no presente caso, cada vez mais, a legislação urbanística de uso e ocupação do solo seja referência para decisões, servindo de parâmetro para resolução de conflitos fundiários urbanos.

Published: February 2025

<p>The plantation density (PD) is a decisive factor in the agronomical resources of cultivation; as such, in this experiment, the effect of the growth and the productivity of the chaya plants were evaluated, as an associated growing in the cedar-lime system, to determine its optimum PD. The chaya plants were positioned at 1.50 x 3.00 m, utilizing cuttings without leaves; associated with young trees (less than 2 years) of <em>Cedrela odorata</em> and <em>Citrus latifolia</em> in a circular plantation design 'Nelder' of 3154 m<sup>2</sup>. Eight PD from 2602 to 3772 plants·ha<sup>-1</sup> were defined with 10 repetitions. The variables were: rhizogenic potential (RP), growth rate (GR), index of vigor (IV), index of leaf area (ILA) and production of dry biomass (PDB). The results indicated that of the 3046 to 3772 plants·ha<sup>-1</sup> were found to have the best RP, the ILA (5.44) and PDB (8.48 kg·plant<sup>-1</sup>); even though the IV (1.16) and GR (0.51 cm·day<sup>-1</sup>) were the best in 2602 to 2647 plants·ha<sup>-1</sup>. As the primary objective in this specie is the PDB, the PD optimal was 3046 to 3772 plants·ha<sup>-1</sup>.</p>
