1H -NMR Metabolomics Study of the Effect of Cisplatin and Casiopeina IIgly on MDA-MB-231 Breast Tumor Cells

The knowledge of the metabolic processes of designed metallodrugs for cancer treatment is an area that has been not profoundly studied. Casiopeina IIgly (CasIIgly), which belongs to the Casiopeínas® family, is a copper (II) coordination compound that has shown good biological activity against several cancer cells, low toxicity in normal cells, and antineoplastic activity in in vivo murine and xenografted models. In this work we employed a triple-negative highly metastatic breast carcinoma line (MDA-MB-231), which is one of the cancer types with a great mortality index, for 1H-NMR metabolomic analysis using cisplatin and CasIIgly, in order to quantify the effect of metallodrugs in the metabolic profile of this cell tumor line as a consequence of treatment at different times. Our findings indicate that cisplatin mainly contributes to phospholipid biosynthesis while CasIIgly affects processes such as carbohydrates and nucleotides metabolism. Also, we observed that CasIIgly treatment has an important and fast effect over MDA-MB-231 cell metabolism, which makes it a good alternative for treatment in this type of cancer.

Outcomes for Hispanic Patients with Acute Leukemia Treated at Academic Centers

Introduction: Health disparities for underrepresented U.S. minority populations with hematologic cancers contribute to differential treatment and higher death rates. The Hispanic population (including people of Mexican, South/Central American, Cuban, Puerto Rican, or other Spanish-speaking cultures, regardless of race) collectively constitutes the largest minority group in the United States. Hispanic patients have been reported to have an increased incidence of B-cell acute lymphoblastic lymphoma (B-ALL) and acute promyelocytic leukemia (APL). While APL is associated with favorable outcomes compared to other acute leukemias, registry data suggest poorer outcomes in Hispanic patients with both acute lymphocytic leukemia (ALL) and acute myeloid leukemia (AML). The Hispanic paradox is an epidemiological paradox that refers to the finding that Hispanic patients have paradoxically comparable, or better, health outcomes compared to their U.S. non-Hispanic White counterparts despite barriers to care such as lower socioeconomic status. This paradox has also been reported in hematologic malignancies. Definitive data regarding differences in outcome between Hispanic and non-Hispanic patients with acute leukemias (AL) are lacking. We sought to compare outcomes of Hispanic patients and non- Hispanic patients with acute leukemia with access to care, and examine whether the Hispanic paradox reported in hematologic malignancies is attributable to enrichment of patients with highly curable disease such as APL. Methods: Using data from a Vizient Clinical Data Base, a healthcare claims database, we identified patients with leukemia using ICD 10 codes for acute leukemia. Adult patients with AL, ages 18-89 who were treated between January 2020 and June 2021 were evaluated. Data from 121 academic centers was included. We focused on academic centers to limit the impact of access to care . Demographic information was obtained from the registry, to which ethnicity was self-reported. Patients were stratified by age, and we compared complication rates, number of complications, number of deaths, percent deaths and mortality index between Hispanic and non-Hispanic patients. The key metric used to compare outcomes of Hispanic patients with non-Hispanic patients was the severity adjusted mortality index, which is the ratio of observed mortality over expected mortality for patients with the same diagnosis in this registry. Chi-squared test is used for to determine the statistical significance of differences in mortality (by age group) in Hispanics v. non-Hispanic patients. Initial analysis included all patients with acute leukemias, and the data was subsequently reanalyzed excluding patients with APL, as APL is known to portend a favorable prognosis. Results: A total of 29,967 patients were with acute leukemia were evaluated; of these patients, 2903 identified as Hispanic and 27,064 were non- Hispanic. As seen in table 1, patients of Hispanic origin generally had lower treatment related complication rates in all age groups compared to their age matched non-Hispanic counterparts. Except for the 51-64 and 80-84 age groups the mortality index was lower in Hispanic patients compared to non-Hispanic peers. Differences in mortality between Hispanic and non-Hispanic patients in all age groups were not statistically significant. Trends to a lower mortality index in Hispanic patients are highlighted in green in table 1. When patients with APL were excluded from the analysis, the trend lower mortality in Hispanic patients in most age groups persisted. Again, the mortality index was comparatively higher in hispanic patients in the 51-64 and 80-84 age groups, but differences in mortality between Hispanic and non- Hispanic patients were not statistically significant. Exclusion of APL patients did not have a significant impact on the complication rate or mortality supporting that the Hispanic paradox is independent of higher rates of very favorable risk myeloid malignacies in this population. Conclusions: Hispanic patients with access to academic cancer centers have the potential for non-inferior outcomes compared to non-Hispanic patients. Equivalent outcomes as assessed by mortality index were not attributable solely to the higher incidence of very favorable risk disease such as APL in the Hispanic population. Figure 1 Figure 1.

Coral reef condition at the Putri Island, Bangka Regency

Putri Island is one of the unique islands which is located in the Bangka Regency. Putri Island has biodiversity ecosystem except for mangrove ecosytems. This study aims to analyze the extent of coral reefs in the shallow waters of Putri Island, and analyze the condition of coral reefs (percentage of cover, life form and coral mortality index). The research was conducted in April – September 2021 at Putri Island with using Line Intercept Transect (LIT) method. The research station divided in to 4 stations where was determined by purposive sampling The results show a map of the distribution of coral reefs in the Putri Island, Bangka Regency. Result show that condition of coral reefs at the research location is a good condition.

Status Terkini Tutupan Terumbu Karang di Perairan Dangkal Pulau Bedil, Desa Labuan Bajo, Kabupaten Sumbawa, NTB

Bedil Island is included in the Keramat, Bedil, and Temudong Small Island Park (TPK), which was approved by the Regent of Sumbawa. Administratively, this island is included in the Labuan Bajo Village area, Sumbawa, NTB. There is the existence of coral reef ecosystems in these waters that form a reef flat and reef slope profile, that stretches to the southwest and northeast. By its designation as a small island park, the coral reefs in Bedil Island are used as an underwater tourism object. This study aims to determine the current condition of coral reef cover in the waters around Bedil Island, especially in the eastern and southern parts of the island. Coral reefs in the north and west area are limited and there is the existence of seagrass beds. The line intercept transect method is carried out by spreading the roll meter as far as 50 meters on the east and south sides of the island with a depth of 2-3 meters. The coral lifeform that is tangent with the roll meter is then recorded and then analyzed for the average percent cover, clustering status, and coral mortality index. Coral reefs in the eastern and southern parts of Bedil Island are classified as very good/excellent because they have a percent cover value above 75%. In addition, the coral mortality index value is also relatively small which indicates that the corals are living well. Clearwater conditions and locations far from human settlements are thought to be factors that support coral survival. However, the presence of dead coral algae and rubble still indicates a threat of damage even though the value is small. Algae life on the surface of dead coral also indicates that the coral has been dead for a long time.

Anesthetic Preconditioning of Traumatic Brain Injury is Ineffective in a Drosophila Model of Obesity

We tested the hypothesis that obesity influences the pharmacodynamics of volatile general anesthetics (VGAs) by comparing effects of anesthetic exposure on mortality from traumatic brain injury (TBI) in lean and obese Drosophila melanogaster. We induced TBI with a High-Impact Trauma device. Starvation-selection over multiple generations resulted in an obese phenotype (SS flies). Fed flies served as lean controls (FC flies). Adult (1-7 day old) SS and FC flies were exposed to equianesthetic doses of isoflurane or sevoflurane either before or after TBI. The principal outcome was percent mortality 24 hours after injury, expressed as the Mortality Index at 24 hours (MI24). TBI resulted in lower MI24 in FC than in SS flies (21 (2.35) and 57.8 (2.14), respectively n= 12, p=0.0001). Preexposure to isoflurane or sevoflurane preconditioned FC flies to TBI reducing the risk of death to 0.53 [0.25 to 1.13] and 0.82 [0.43 to 1.58], respectively, but had no preconditioning effect in SS flies. Postexposure to isoflurane or sevoflurane increased the risk of death in SS flies. Only postexposure to isoflurane increased the risk in FC flies (1.39 [0.81 to 2.38]). Thus, obesity affects the pharmacodynamics of VGAs, thwarting the preconditioning effect of isoflurane and sevoflurane in TBI.

Observational study on the efficiency of Neonatal Emergency Transport in reducing mortality and morbidity indexes in Sicily

In these last 25 years, the Neonatal Emergency Transport (NET) service has been widely improved in Italy. To date, all National areas are covered by a NET service; 53 NET centers have been activated in all the Italian territory. Herein, the authors present an observational study to evaluate the rate of infantile mortality after introduction of NET in Sicily, and to study the efficiency of this service in reducing these rates of mortality in vulnerable neonates, transported from primary care birth centers to tertiary facilities to undergo to specialized NICU assistance. All neonates who required an emergency transport by NETS were included. No exclusions criteria were applied. Demographic and regional infantile mortality data, expressed as infant mortality rate, were selected by the official government database (ISTAT- National Statistic Institute—http://www.istat.it). All data were respectively divided into three groups: data concerning transport, clinical condition, and mortality of the transported patients. We transported by NET 325 neonates. The analysis of the infant mortality rate (per 1.000 live births) in Catania from 2016 to 2018 was reduced compared to the same rate calculated before NETS activation (4.41 index before 2016 vs 4.17 index after 2016). These data showed an increase in other provinces (Enna, Caltanissetta, and Agrigento). 61% of neonates showed a respiratory disease. During the study period the proportion of neonates with a Mortality Index for Neonatal Transportation—MINT < 6 has been reduced, while there was an increase of neonates with higher Transport Risk Index of Physiologic Stability-TRIPS score results. The slight decrease of infantile mortality in Catania during the first three years after introduction of NET follows the same trend of all Italian territories, showing the importance of this service in reducing infantile mortality.

Critical obstetric conditions during pandemic (COVID-19) and pre-pandemic years

Aim. To assess the structure of critical obstetric conditions and maternal mortality in Transbaikal Region in pandemic (COVID-19) and pre-pandemic years (2020 and 2019, respectively).Materials and Methods. We retrospectively analysed “near miss” (NM) and maternal deaths (MD) in 2019 and 2020, further calculating the severe maternal outcome ratio (SMOR), the summary indicator which includes both NM and MD per 1000 live births.Results. In a pandemic year (2020), we observed an increase in SMOR in comparison with a pre-pandemic year (3.0 vs 2.0, respectively). In 2019, maternal mortality was exclusively caused by obstetric complications, while extragenital pathology (cardiovascular disease and COVID-19) was responsible for that in 2020. However, the main causes of «near miss» in 2019 and 2020 were similar, including obstetric haemorrhage because of placental abruption and severe pre-eclampsia. Maternal near-miss mortality ratio (MNM/MD) increased from 7.3: 1 in 2019 to 11.3: 1 in 2020, and mortality index (MD/(MNM + MD) × 100) reduced from 12.0 to 8.1. Therefore, fewer women with life-threatening conditions died in 2020 as compared with 2019, indicating a better quality of obstetric care.Conclusion. Analysis of the critical obstetric conditions can probably find regional issues of maternal healthcare during the COVID-19 pandemic and propel the policy makers to find additional resources to minimise maternal morbidity and mortality.

Methodological elements for the comparative analysis of the first wave of the Covid-19 epidemic in France, Italy, and Spain

The three European countries included in the northwest littoral of the Mediterranean region – Italy, France and Spain – reported their first cases of the SARS-CoV-2 coronavirus early in 2020. The subsequent epidemic strongly impacted these countries, challenging the healthcare systems efficiency, and the capacity and transparency of their public statistics structures. Because public statistics were not fully adapted to such a new health situation, the available official data could not wholly describe the epidemic correctly. This paper developed an indicator derived from the prevalence of SARS-CoV-2 aiming to describe the time and spatial dynamics of the epidemic. Although the analysis was not applied to France due to the lack of data available, the comparative analysis among Spain and Italy highlighted some similarities and certain divergences, partially attributable to the features of each country‘s national demographic patterns and the peculiarities of applied health protocols. Finally, mortality during the first wave of the epidemic has been analysed for the three countries, demonstrating higher mortality index in Spain, although the reported number of SARS-CoV-2 declared deaths does not explain a portion of this mortality excess.

Understanding Public Sector Innovation from A Local Perspective: Contra War (Contraceptive for Women at Risk) Innovation Study in Malang Regency

This research aims to understand public sector innovation from a local perspective with a study of the Contra War (Contraceptive for Women at Risk) innovation study in Malang Regency. This innovation aims to reduce maternal and infant mortality rates. This research used a qualitative study with document analysis. Researchers analysed documents from various sources such as official government reports, government regulations, online media news, scientific literature, and books. The result shows that the Contra War innovation has not significantly reduced maternal and infant mortality, but gradually the Contra-War has reduced maternal mortality index (Angka Kematian Ibu/AKI) cases from 27 in 2019 to 14 cases. Meanwhile, infant mortality rate (Angka Kematian Bayi/AKB as many as 62 people in 2020. Another side, the sustainability of innovation has not gone well because of low participation, innovative organisational capacity, and transformational leadership. Therefore, researchers provide suggestions for increasing public participation, collaborating with third parties, and creating innovative work ecosystems and bureaucratic structures.
