Psychedelics and psychoanalysis: The journey from talking cure to transformation
Authors: Lichtenstein Jonathan , Hoeh Nicholas R 
Published: August 2024

AbstractThere is a developing dialogue between the psychoanalytic and psychedelic fields of psychotherapy. This paper contributes to this emerging collaboration by applying Winnicott's concept of transitional experience to psychedelic clinical work. By analyzing two Ketamine-Assisted Psychotherapy (KAP) cases, we explore in depth how transitional experience facilitates psychedelic transformation. We review clinical touch and introduce hand-holding as a transformational experience that can occur in the amplified relational field of the psychedelic space. Applying these ideas will deepen clinicians' theoretical understanding and experiential practice of KAP.

El Fenómeno del Niño y la prevalencia de enfermedades infecciosas: revisión
Authors: Molleda Patricia , Velásquez Serra Glenda 
Published: August 2024

Climate changes caused by the El Niño oscillation southern (ENSO) significantly influence human diseases, because they are related to anomalies in precipitation or periods of drought. The aims of this paper are: to evaluate the anomalies of the average sea surface temperature, to calculate the average sea surface temperature of the Niño and Niño 1+2 regions, to contextualize infectious pathologies according to their classification: viral, bacterial, parasitic and caused by fungi in the geographical areas or countries of the Region where they have been studied in the historical context (1982-1983; 1997-1998 and 2016-2017) periods of the ENSO considered strong. A bibliographic, descriptive, documentary, retrospective and cross-sectional review was carried out during the months of October 2023 to March 2024. Sea Surface Temperatures (SST) are higher than average, observed throughout the equatorial Pacific Ocean, with anomalies being greater in the central and central-eastern Pacific. For ENSO 2023-2024, in the Niño 4 region the last calculated values of the Niño index remained at a temperature of +1.4 °C, in the Niño 3,4 region it was +1.9, in the Niño -3 region it was +2.0 °C while in the Niño-1+2 regions it weakened to +1.0 °C. The highest incidence and prevalence of ENSO infection (1997-1998) in Ecuador stands out, accounting for an increase in 13 infectious pathologies. Attention must be paid and the links between the environment and the risk of infection must be better understood.

Published: August 2024

The goal of health systems implemented at international, national, or regional level is to improve health effectively and efficiently by all available means, including community efforts, special education, military, and government, thereby improving public health at all levels. Health issues as national issues need top priority. Inequalities in mortality risk are inseparable from issues surrounding the health policy debate. Public health level is assessed through several indicators. Health Policy in law regulates the right to health. Proposed health system goals at international, national, or regional levels are usually not measured by human rights standards and instruments. Universal Health Insurance is expected to provide benefits. Health services are provided as medicines and treatments. This review aimed to determine trends in number of publications and visualize linkages of health insurance topics through bibliometric analysis. This was a systematic review with steps following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) diagram using 661 scientific articles published between 2004 and 2022, followed by inclusion and exclusion criteria from Dimensions database. Review of articles was by means of Vosviewer app. Our study results contributed to research roadmap development on health insurance. The limitation is that app.dimension.ai and google scholar databases are periodically updated, such that bibliometric analysis of health insurance should be repeated in the near future. Because this bibliometric analysis only extracted scientific article data from app.dimension.ai database, further research should add another database for broader and more comprehensive understanding of health insurance.

The book is pioneering in Poland. but also in Central Europe. lt shows the mechanisms of adaptation to the systemie transformation in Poland after 1989, based on the analysis of narratives of people barn in 1960, 1970 and 1980 who are representatives of diverse social milieus and have different professional and life experiences. The reader will find here a model application of the biographical research methodology developed by Fritz Schütze for a series of case studies. which makes this publication the most extensive work using the indicated method for research on transformation. The authors of the individual chapters, emphasizing the individual agency of the subjects, avoid the pitfalls of neoliberal discourse shifting responsibility for their fates onto individuals. Apart from the analysis of autonomous ways of agency, they show various potentials of losing control over one’s life, biographical trajectories, as well as biographical resources, mainly of a family nature, which serve to deal mare effectively with the consequences of systemic transformation.

The book has received funding from the National Science Center, Poland under grant agreement No. UMO-2013/09/B/HS6/03100 “Experience of the Process of the Transformation in Poland. A Sociological Comparative Analysis Based on Biographical Perspective”

Abstract

The environmental and human health risks of chemical insecticides have prompted extensive searches for alternative methods to protect stored products. Recently, nanoparticles have been considered as promising alternatives to synthetic chemical products. In this study, ZnO nanoparticles (NPs) were synthesized using Cystoseira baccata algae extract, and characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR), and Field emission scanning electron microscopy (FE-SEM). Three different types of ZnO NPs, ZnO-A, ZnO-B, and ZnO-C, were synthesized using algae extract by two different methods. Their insecticidal activity was evaluated and compared with the chemically synthesized ZnO-D NPs against the cowpea weevil, Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae) on stored cowpea. Biosynthesized ZnO-A, ZnO-B, and ZnO-C NPs exhibited higher activity against C. maculatus when compared with ZnO-D NPs. Porous ZnO-A NPs with the smallest particle size (24.3 nm) were determined to be the most toxic nanoparticles, causing the highest mortality rate of C. maculatus adults after five days of exposure. While ZnO-D NPs were the least effective for C. maculatus control. A significant oviposition inhibition (35.1 to 44.9%) and progeny reduction (35.7 to 45.6%) was also observed for insects exposed to ZnO-A NPs-treated cowpeas at 500 to 2000 mg kg-1. The average weight loss of cowpea seeds treated with ZnO-A, ZnO-B, and ZnO-C NPs at 2000 mg kg-1 was 23.8, 28.1, and 33.5%, respectively. The potential of using biosynthesized ZnO NPs as a viable alternative for controlling C. maculatus in stored cowpeas is discussed.

Abstract

Epidermal growth factor receptor 2 (HER2) and programmed cell death ligand 1 (PD-L1) are pivotal therapeutic targets in advanced gastric cancer (GC). Nevertheless, the correlation between them, along with the clinical and genomic characteristics, and prognosis differences across distinct molecular subtypes, remains elusive. In this retrospective study, 390 advanced GC patients provided both tumor tissue and paired blood samples for Next-Generation Sequencing (NGS) of 639 tumor-related genes, along with PD-L1 immunohistochemical staining. HER2 amplification was further validated using FISH testing in 254 patients. We analyzed the clinical and molecular characteristics among subgroups based on HER2 amplification and PD-L1 CPS score. The highest consistency with FISH for HER2 amplification was observed when the positive threshold for NGS detection was set at 2.5. TP53 mutation rate peaked at 59%, significantly higher in cases with HER2 amplification (P < 0.01). Patients with both HER2 amplification and TP53 mutations exhibited notably shorter survival compared to cases with only TP53 mutations (P < 0.05). Furthermore, HER2 amplification did not correlate with PD-L1 expression levels. Stratified analysis of PD-L1 expression revealed distinct clinical and molecular features. Patients with higher PD-L1 expression levels (CPS ≥ 5) showed a higher tumor mutational burden (TMB) and microsatellite instability-high (MSI-H) status. Additionally, these patients exhibited enriched mutations in key signaling pathways such as PI3K, TGFβ, and Wnt/β-catenin. In conclusion, our study highlights the prognostic significance of HER2 amplification and TP53 mutations in advanced GC. Stratified analysis of PD-L1 expression may help identify candidates for targeted and immunotherapy in this patient population.

Abstract

Background
Celiac plexus block has been commonly utilized for the treatment of chronic pancreatitis associated abdominal pain. Prospective studies suggest efficacy in 30 to 50% of patients, although no randomized sham-controlled trials have been performed. The objective of this study is to assess the effect of endoscopic ultrasound (EUS)-guided celiac plexus block on abdominal pain in patients with documented chronic pancreatitis.
Methods
This is a 2-arm randomized sham-controlled trial with blinded evaluators. The study will be conducted at multiple academic sites in the United States who are members of the United States Pancreatic Disease Study Group (USPG). Patients referred for EUS to exclude chronic pancreatitis as a cause of abdominal pain as well as those with established painful chronic pancreatitis undergoing EUS for another indication will be eligible. At the time of EUS with confirmation of chronic pancreatitis by standard EUS diagnostic criteria, patients will be randomized to either celiac plexus block or sham whereby an anesthetic and steroid combination will be injected into the celiac plexus or saline will be injected into the gastric lumen with the same type of needle as used for celiac plexus block, respectively. The main outcome measure will be a 50% reduction in abdominal pain using the Brief Pain Inventory Short Form (BPI-SF) at one month post intervention. A number of secondary outcomes will be measured including visual analog scale (VAS), Comprehensive Pain Assessment Tool-Short Form (COMPAT-SF) pain scores and quality of life using a pancreas-specific validated measure (PANQOLI).
Discussion
In this study, the effect of celiac plexus block on abdominal pain in patients with chronic pancreatitis will be compared to a sham intervention. This randomized trial will offer a definitive assessment of the role of celiac plexus block for the treatment of abdominal pain in this setting.
Livestock Poisonous Plants, their Ecology, and its Impact on Livestock Production Performance in Southwest Ethiopia
Authors: Mohammed Seid , Wato Tamirat 
Published: August 2024

Abstract

In the southwestern Ethiopia there is huge livestock population with dense forest that requires more extensive assessment and documentation on poisonous plants, which are a neglected research area. Therefore this research was conducted to identify livestock poisoning plants with their respective ecology, seasons of occurrences and to assess effect on livestock production performance in the region from February to November 2022 with our key informants of farmers, traditional animal healers, and veterinarians. Structured questionnaire were used to collect information related to toxic plants for livestock and their associated risk factors. The most common poisoning plants identified in the study area includes Datura stramonium, Rumex crispus, Prosopis juliflora Ajuga alba, Solanum americanum, Amaranthus cruentus, Albizia gummifera, Cyperus rotundus, Uebelinia kiwuensis Xanthium strumarium, Tribulus terestris, Medicago polymorpha, Euphorbia tirucalli, Hedera canariensis and Trifolium burchelianum. Lack of green feed, shortage of pastures and overgrazing are the predisposing factors for livestock to consume poisoning plants. Most of the livestock poisoning plants were distributed in all agroecologies of lowland, midland, highland. Those poisonous plants were growing in the early rainy season and green in the dry season as well. Bovine species are the most frequently poisoned livestock followed by sheep, goats and equine by showing different symptoms. Traditional animal healers and farmers used different treatment mechanisms to relieve their poisoned animals by providing a mixture of soap and ash, soap with milk and cold water, garlic, alcohol, and other plant roots or leaves at different ratio, depending on the species of animal affected and type of poison. Physical control, biological mechanism and herbicide application of the infested areas by toxic plant, good range management, and wise grazing strategies can reduce the degree of poisoning of livestock.

Abstract

Upwelling is an oceanographic phenomenon characterized by the upward movement of cold nutrient-rich water from the deep ocean to the surface. It plays a crucial role in supporting the productivity and biodiversity of the coastal ecosystem. The Southwest coast of India experiences coastal upwelling during the southwest monsoon (SWM-June to August) due to the influence of wind featuring calm, muddy waters and suspended sediments close to the coast, especially the mudbanks in Alappuzha. Sediment microbes play crucial roles in various ecological processes and are essential components of marine ecosystems. Understanding the spatiotemporal variance within the community is vital to comprehend the mechanisms underlying the biogeochemical cycles. However, the bacterial community structure and function in the upwelling and Mudbank regions on the Alappuzha coast have received little attention. In this study, we analyzed the abundance and diversity of bacterial communities in sediment during pre-monsoon (PRM) and monsoon (MON) periods in three stations, M1, M2, and M3. During the MON, mud banks appeared only at station M2, while upwelling occurred across the study region. Comparative analysis of family to species level showed that PRM and MON seasons have distinct microbial communities with variations in their relative abundance in the M2 (mudbank and upwelling prevalent) compared to the other two stations such as M1 and M3 (upwelling alone). The total count (0.32–6.12×106) (TC) and total viable count (0.62–2.56×106) (TVC) indicating bacterial abundance were higher in the PRM season than in MON. However, the relative abundance of Proteobacteria (39.46 to 81.43%) was comparatively high in all the stations during both seasons, with higher abundance during MON than PRM. In the present study, Vibrio photobacterium and Ferrimonas were detected and their relative abundance is comparatively higher in the upwelling period compared to PRM. The abundance of lower trophic levels communities such as the genus Bacillus, Tepidibacter, Vibrio, Photobacterium, Ferrimonas, Clostridium, Desulfococcus etc. showed seasonal and spatial variation in the mudbank and the upwelling regions. Our results indicate the variations in bacterial community structure which could be coupled with variations in organic substances, changes in currents, and oceanographic features.
