The potential utilization of a zooplankton community as a live feed in ecological shrimp ponds in Ca Mau province, Vietnam
Authors: Tran Ngoc Diem My , Tran Le Quang Ha 
Published: September 2024

Abstract
Although aquatic larvae need natural food, relevant sources in the food web have not been extensively researched and used in aquaculture. The zooplankton community at the ecological black tiger shrimp (Penaeus monodon) ponds in the Ca Mau mangrove forest in Vietnam was studied for its potential as a natural food source in these and other, similar ecosystems (fish ponds, mollusc ponds). This study examined eight ecologically distinct shrimp ponds in the dry, transitional, and rainy seasons. Thirty-seven zooplankton species from 31 genera, 19 families, and 4 phyla were identified in these shrimp ponds. The zooplankton density was 1167-53 330 individuals/m3 with over half the species and density being copepods. Five Copepoda species were common and of high population density, including Limnoithona sinensis, Thermocyclops hyalinus, Tropocyclops prasinus, Eodiaptomus japonicus, and Euaugaptilus elongatus. This natural food can feed shrimp larvae and adults and thereby supply high quality nutrients for their development. However, the pond’s zooplankton was lacking in diversity. Thus, providing natural nutrients to the pond may increase zooplankton diversity and facilitate sustainable aquaculture.

Caligus rogercresseyi (Copepoda, Siphonostomatoida): analysis of infestation rate on farmed Salmo salar in the Aysen region (Patagonia, Chile)
Authors: Barile Juan , Carreño Eriko , De los Ríos-Escalante Patricio 
Published: September 2024

Abstract
Caligus rogercresseyi is an ectoparasitic copepod that affects salmon farms, generating negative effects on the productivity of the industry. The present study consisted of applying data science and machine learning techniques to data on C. rogercresseyi infection from Salmo salar farming centres in the Aysen region. The multiple regression models show a significant inverse relationship between total C. rogercresseyi infections (females, males, both adults together, and juveniles), with latitude and temperature, and a significant direct relationship with longitude and salinity for the total data. The results agree with observations for infection rates of C. rogercresseyi in farmed salmon in the southern part of Chile.

Published: September 2024

Abstract
The growth of the Pacific white shrimp, Penaeus vannamei was analysed with data from nine earthen ponds in three aquaculture farms located at the mouth of the Gulf of California in the state of Sinaloa, Mexico. Each farm has a different source of water supply: marine, estuarine-freshwater, and estuarine-hypersaline. Growth was estimated with a multi-model approach using five versions of the Schnute model. The parametrization was done with maximum likelihood as an objective function, and observing the variance criterion. The best model was selected via the Bayesian information criterion. The Schnute model reproduced the Von Bertalanffy model in the estuarine-freshwater conditions; the Logistic model in the estuarine-hypersaline situation; and the Gompertz model in the case of the marine water source. Differences in growth curves were corroborated via the Kimura ratio test. The difference in water quality was most evident in the factor salinity. The best performance was obtained with the estuarine-freshwater water source. The results support the hypothesis that postlarvae and juveniles exhibit better growth in brackish water than when supplied from a marine water source.

Abstract
The Special Operations Battalion of Rio de Janeiro (BOPE-RJ) carries out high-risk missions in an urban warfare environment, such as exposure to acute stress situations, such as shootings and confrontations with criminals, placing high physical and psychological demands on its members. This study investigated the kinetics of the growth hormone and insulin-like growth factor (GH/IGF-I) axis and the serum levels of testosterone and cortisol in soldiers belonging to BOPE-RJ. It is a cross-sectional study with 75 volunteers divided into two groups: Control Group (CG) and Mission Group (MG). Blood was collected once from both groups, between 8 and 9 a.m., in a specially equipped room at the military training centre. The collection respected the volunteers’ real work routine and was performed when the groups changed shifts. Contrary to expectations, no changes were found between the groups for the indicators analysed, except for cortisol, where there was a statistically significant difference. The mean cortisol levels were 10.86 μg/dl for CG and 12.27 μg/dl for MG. These findings have significant implications for BOPE-RJ and similar units. While they suggest that these soldiers may be able to carry out high-risk missions safely and effectively even under stressful conditions, the potential long-term consequences of chronic stress exposure on their physical and mental health require further investigation.

Published: September 2024

This study compares the features of homicide-suicide in Russia and Pakistan. To understand this, we conducted a content analysis of news reports about homicide-suicide published in Pakistani and Russian newspapers between March 2020 and May 2023. We identified 35 and 104 homicide-suicide cases in Pakistani and Russian media, respectively. Men were three to five times more likely to commit homicide-suicides than women (3.16: 1 in Russia; 4.83: 1 in Pakistan). Accounting for over 65.73% of all homicide-suicides, spousal homicide-suicides and filicide-suicide were the most common homicide-suicides in both regions. Filicide-suicides were more often done by Russian women and extra-family homicide-suicides by Pakistani women. Reasons for homicide-suicides in Pakistani women were divorce or separation and in Russian women – mental disorders. With the difference of homicide in the victims, Pakistani victims were aged 15–30 years, while Russian were 31–45 years and 46 years and older. There were more similarities in homicide-suicides than differences.

Published: September 2024

Background: Implementing shared decision-making in oncology practice is often limited, particularly integrating the patient’s context into decision-making. To improve this, we conducted a quality improvement project, CONtext. CONtext attempts to accomplish this by: (1) Integrating the patient’s context into shared decision-making during consultation with the medical oncologist; (2) Actively involving the GP and case manager (a specialized oncology nurse), who often have knowledge about the patient’s context, and; (3) Giving the person with advanced cancer a time-out period of up to 2 weeks to consider and discuss treatment options with others, including close family and friends. Aim: To explore how persons with advanced cancer and their involved professionals experienced shared decision-making after the introduction of CONtext. Design: A qualitative embedded multiple-case study using in-depth interviews analysed with inductive content analysis. Participants: A purposive sample of 14 cases, each case consisting of a patient with advanced cancer and ideally their medical oncologist, case manager, and GP. Results: Four themes were identified: shared decision-making is a dynamic and continuous process (1), in which the medical oncologist’s treatment recommendation is central (2), fuelled by the patients’ experience of not having a choice (3), and integrating the patient’s context into shared decision-making was considered important but hampered (4), for example, by the association with the terminal phase. Conclusions: The prevailing tendency among medical oncologists and persons with advanced cancer to prioritize life-prolonging anticancer treatments restricts the potential for shared decision-making. This undermines integrating individual context into decision-making, a critical aspect of the palliative care continuum.

Background: In recent years, both meditation and psychedelics have attracted rapidly increasing scientific interest. While the current state of evidence suggests the promising potential of psychedelics, such as psilocybin, to enhance meditative training, it remains equivocal whether these effects are specifically bound to psilocybin or if other classical psychedelics might show synergistic effects with meditation practice. One particularly promising candidate is N,N-dimethyltryptamine (DMT), an active ingredient of ayahuasca. Aim: This study aims to investigate the effect of the psychedelic substance DMT, combined with the monoamine oxidase inhibitor harmine ( DMT-harmine), on meditative states, compared to meditation with a placebo. Method: Forty experienced meditators (18 females and 22 males) participated in a double-blind, placebo-controlled study over a 3-day meditation retreat, receiving either placebo or DMT-harmine. Participants’ levels of mindfulness, compassion, insight, and transcendence were assessed before, during, and after the meditation group retreat, using psychometric questionnaires. Results: Compared to meditation with a placebo, meditators who received DMT and harmine self-attributed greater levels of mystical-type experiences, non-dual awareness, and emotional breakthrough during the acute substance effects and, when corrected for baseline differences, greater psychological insight 1 day later. Mindfulness and compassion were not significantly different in the DMT-harmine group compared to placebo. At 1-month follow-up, the meditators who received DMT and harmine rated their experience as significantly more personally meaningful, spiritually significant, and well-being-enhancing than the meditators who received placebo. Conclusion: Investigating the impact of DMT-harmine on meditators in a naturalistic mindfulness group retreat, this placebo-controlled study highlights the specific effects of psychedelics during meditation.

Published: September 2024

Objective Artificial intelligence (AI) could help medical practitioners in analyzing radiological images to determine the presence and site of bowel obstruction. This retrospective diagnostic study proposed a series of deep learning (DL) models for diagnosing bowel obstruction on abdominal radiograph. Methods A total of 2082 upright plain abdominal radiographs were retrospectively collected from four hospitals. The images were labeled as normal, small bowel obstruction and large bowel obstruction by three senior radiologists based on comprehensive examinations and interventions within 48 hours after admission. Gradient-weighted class activation mapping was used to visualize the inferential explanation. Results In the validation set, the Xception-backboned model achieved the highest accuracy (0.863), surpassing the VGG16 (0.847) and ResNet models (0.836). In the test set, the Xception model (accuracy: 0.807) outperformed other models and a junior radiologist (0.780) but not a senior radiologist (0.840). In the AI-aided diagnostic framework, the junior and senior radiologists made their judgements while aware of the Xception model predictions. Their accuracy significantly improved to 0.887 and 0.913, respectively. Conclusions We developed and validated DL-based computer vision models for diagnosing bowel obstruction on plain abdominal radiograph. DL-based computer-aided diagnostic systems could reduce medical practitioners’ workloads and improve diagnostic accuracy.

Published: September 2024

Background: The Ghanaian elderly population is increasing at the fastest rate and this has become a burden as the rate is not proportional to the investment in health to meet their deteriorating health needs. This creates discrepancies and inequalities in healthcare access and coupled with poor healthcare provider services, the inequalities widen. Poor care services are related to poor knowledge and bad attitudes of care providers hence this study seeks to explore the health practitioners’ level of knowledge, attitude, and practice (KAP) toward geriatric care. Methods: The study used a cross-sectional survey design with a simple stratified random technique to select study participants. Out of 257 participants who were sampled for the study, 215 responses were received, representing 83.6% response rate. However, 200 questionnaires were complete (93%) and valid for analysis, which consisted of 166 nurses, representing 83% valid responses, and 34 medical officers, physician assistants, and other allied health care providers, representing 17% valid responses from these professionals. A structured questionnaire was used to assess KAP using the knowledge about Older Patients Quiz (KOP-Q) and Kogan’s Attitudes toward Old People Scale (KAOP). Using a mean score of 80%, knowledge, attitude, and practice were dichotomized into good or bad. The Kruskal-Wallis H test was used to compare mean rank across health professionals’ knowledge, attitude, and practice of geriatric care. Results: It shows that the majority (94%) of participants have low levels of knowledge in geriatric care. The majority (84%) of participants do not practice good geriatric care. Differences in knowledge exist among health providers and were statistically significant ( P = .045). Doctors had the lowest mean knowledge score (78.61). Nurses (100.27) and physician assistants (106.15) had moderate mean knowledge score ranks. Although not statistically significant, the rank order for practice scores from highest to lowest was: physician assistants (112.95), nurses (99.19), and doctors (79.21). There were however no statistically significant differences between professions in practice scores ( P = .067), or attitude scores ( P = .097). Conclusion: Health care providers have low knowledge and, bad attitude toward aged care and this may be related to their service delivery which may affect the aged patronage of healthcare services. This is a wake-up call for authorities to organize continuous professional development to enable care providers to improve their service delivery.

Published: September 2024

Background To report revascularization of a superior mesenteric artery (SMA) ostial occlusion via the Arc of Buhler. Case Report A 62-year-old female presented with 2 months of recurrent abdominal distension and postprandial pain. Computed tomography angiography (CTA) revealed ostial occlusion of the SMA with distal perfusion via the Arc of Buhler (connecting the celiac trunk and SMA). Conventional endovascular techniques failed. A 0.014 guidewire was passed retrograde through the occlusion via the Arc of Buhler. The guidewire was captured from the femoral sheath and balloon angioplasty with stent placement was performed. The patient had complete symptom resolution post-procedure. Conclusions Retrograde revascularization via the Arc of Buhler is an effective method for treating the initial segment occlusion of the SMA.

Published: September 2024

Background: Patients with mediastinal lymph node enlargement (MLNE) are diagnosed depending on lymph node biopsy. Whereas, how to obtain larger tissue masses from mediastinal lymph nodes and improve the diagnostic yield of the disease remains to be investigated. Objectives: Aiming to assess the diagnostic value of endobronchial ultrasound-guided intranodal forceps biopsy via transbronchial laser photoablation (EBUS-IFB-TLP) in patients with MLNE. Design: A prospective, self-controlled study. Methods: This study was conducted on 67 MLNE patients requiring a lymph node biopsy for diagnosis at the Henan Provincial People’s Hospital and the Fuwai Central China Cardiovascular Hospital in China, from January 2020 to December 2022. Each patient underwent endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA group) and EBUS-IFB-TLP (EBUS-IFB-TLP group) on the same mediastinal lymph node for biopsies. The operation time, diagnostic efficiency, and complication rates of the two biopsy methods were compared. Results: The number of diagnosed patients in the EBUS-IFB-TLP and the EBUS-TBNA groups was 65 (97.0%) and 57 (85.1%), respectively ( p = 0.021). In the EBUS-IFB-TLP group, 28 cases (96.6%) were diagnosed with lung cancer and were classified into different epithelial types. In the EBUS-TBNA group, there were 27 cases (93.1%) diagnosed with lung cancer, of which 26 (89.7%) were classified into different epithelial types. There were 37 (97.4%) and 30 (78.9%) non-lung cancer patients diagnosed in the EBUS-IFB-TLP and EBUS-TBNA groups, respectively ( p = 0.039), while 27 cases (96.4%) of sarcoidosis in the EBUS-IFB-TLP group and 20 cases (71.4%) of sarcoidosis in the EBUS-TBNA group were diagnosed ( p = 0.016). The percentages of intraoperative mild to moderate bleeding complications were 23.9% (16/67) and 14.9% (10/67) in the EBUS-IFB-TLP and in the EBUS-TBNA groups, respectively ( p = 0.109). Conclusion: This study demonstrated that EBUS-IFB-TLP could be a feasible and effective method in the diagnosis of patients with MLNE, presenting an analogous safety profile compared with EBUS-TBNA. Further studies are needed to verify the diagnostic performance of EBUS-IFB-TLP for MLNE.
Distinct characteristics and progression patterns of facet joint structural lesions in radiographic axial spondyloarthritis
Authors: Liao Simin , Cheng Liuquan , Zhao Zheng , Zhu Jian , Huang Feng 
Published: September 2024

Background: Both vertebral bodies and posterior elements of the vertebrae (facet joints, FJ) can engage in bone formation in radiographic axial spondyloarthritis (r-axSpA). However, little is known about the specific structural lesions and progression patterns of FJs in r-axSpA. Objectives: To identify specific lesions related to r-axSpA and to investigate the distinct progression patterns by comparing the FJ changes of r-axSpA with that of diffuse idiopathic skeletal hyperostosis (DISH), osteoarthritis (OA), and control group (CG). Design: Single-center, retrospective study. Longitudinal imaging data were retrieved and collected. Methods: Age- and sex-matched patients with complete thoracic and lumbar spine computed tomography (CT) data were included and their bilateral FJs were assessed. FJ changes were divided into erosions, ankylosis, joint-space narrowing, osteophytes, subchondral sclerosis, subchondral cysts, and vacuum phenomena. Average progressed year was defined as “number of changed vertebrae × interval years”/number of changed vertebrae. Results: In all, 50 patients in each group were included. Subchondral cysts and vacuum phenomena were not observed. Bilateral FJ ankylosis (FJA)/erosions in the thoracic and lumbar spine, and unilateral ankylosis/erosions in T1–4, T9–12 were significantly more common in r-axSpA. Joint-space narrowing/osteophytes/subchondral sclerosis were significantly more common in DISH and OA. FJ lesions progressed in 56.34% of vertebrae of r-axSpA. The most common pattern was “FJ normal advanced to ankylosis” (17.54%) which required 2.63 years. It was followed by “erosions advanced to ankylosis” (12.3%) which took 2.05 years, and by “normal FJ advanced to erosions” (11.04%) which took 2.29 years, respectively. Degenerative changes could also progress to FJ erosions/ankylosis (24.83%). The majority pattern in DISH/OA was “FJ changes advanced to subchondral sclerosis/osteophytes/joint-space narrowing.” Conclusion: Bilateral FJA/erosions are r-axSpA-specific lesions. The specific progression pattern for r-axSpA was “FJ changes advanced to ankylosis/erosions.” Repeated CT examination in intervals of at least 2 years will be more appropriate for monitoring FJ progression.
