The effect of density on sex differentiation, sexual dimorphism, stress, and related gene expression in yellow perch

A 180-day experiment was conducted to evaluate the effects of density on sex differentiation, sexual dimorphism, cortisol level, and stress related gene expression. Yellow perch, Perca flavescens, with initial mean body weight of 0.03 ± 0.001 g were reared in three different stocking densities: 1, 2, and 4 fish/L, termed as low (LD), moderate (MD), and high (HD) density, respectively, in a flow-through tank system. Results showed no significant differences in sex ratio in all density groups compared to normal population 1:1, and sexual size dimorphism (SSD) appeared when male and female were as small as the mean size reaching 11.5 cm and 12.3 cm in total length (TL) or 13.2g and 16.9g in body weight (BW), respectively. This female-biased sexual growth dimorphism was more pronounced in LD, although it was observed across all density groups. A significantly higher condition factor (K) of females than males in the LD group, and significantly higher R values of LD and MD than HD with the length/weight (L/W) linear relationships in females, were observed. Parallelly, fish reared in LD showed significantly higher mean body weight than those in the MD and HD groups, but there were no significant differences between the MD and HD. Similar results were also observed in all the other parameters of weight gain, specific growth rate (SGR), condition factor (K), and survival. These findings suggested that high density not only affected growth itself, but also affected SSD, growth trajectory or body shape, and general wellbeing in fish, especially in females. There were no significant differences in gonadosomatic index (GSI) and viscerosomatic index (VSI) among all the density groups; however, the hepatosomatic index (HSI) of LD was significantly higher than MD and HD, suggesting high density affected liver reserves or functions. Physiologically, plasma cortisol level was significantly highest in the LD among all groups, followed by MD, and lowest in HD. At the molecular level, the expression of the 70-kDa heat shock protein (Hsp70), glutathione peroxidase (GPx), and superoxide dismutase (SOD) genes involved in cellular stress were significantly upregulated in the HD group. The most significantly downregulated expression of these genes was consistently observed in the MD when compared to the LD and HD groups. In conclusion, increasing density induced chronic stress in yellow perch without affecting sex differentiation, but negatively affected expression of stress-related genes and mobilization of liver reserve, resulting in poorer wellbeing and reduced SSD, growth, and survival.
GFI1 regulates chromatin state essential in human endothelial‐to‐haematopoietic transition

During embryonic haematopoiesis, haematopoietic stem/progenitor cells (HSPCs) develop from hemogenic endothelial cells (HECs) though endothelial to haematopoietic transition (EHT). However, little is known about how EHT is regulated in human. Here, we report that GFI1 plays an essential role in enabling normal EHT during haematopoietic differentiation of human embryonic stem cells (hESCs).
Enhancing students' well-being with a unified approach based on contextual behavioural science: A randomised experimental school-based intervention.

A new generation of interventions has begun to move towards principles of acceptance that deal with the context and function of psychological events. The aim of this paper is to analyse the effectiveness of a brief contextual behavioural intervention to improve the psychological well-being of secondary school students. This intervention represents a unified model with key processes based on contextual behavioural science, including Acceptance and Commitment Therapy (ACT) and Functional Analytic Psychotherapy (FAP). We conducted an intervention with 94 students (age range 17-19 years), randomly assigned to an experimental group (n = 50) or control group (n = 44). Participants took a pretest and post-test of distress, life satisfaction, psychological flexibility and mindfulness. The intervention consisted of three sessions of 1 h each. The results showed significant differences between the groups in distress and significant differences for the interaction (group × pre-post) in all the other variables. The intervention had greater benefits for girls than for boys. These results may provide a breakthrough, thus leading to a process of evidence-based therapies, which would be responsible for inducing psychological improvements in brief periods, in a population with an increasing risk of distress.
No Difference in Clinical Outcomes for Arthroscopic Suprapectoral Versus Open Subpectoral Biceps Tenodesis at Midterm Follow-up: A Randomized Prospective Analysis

Background: We have previously reported the 1-year outcomes of arthroscopic suprapectoral biceps tenodesis (ASPBT) versus open subpectoral biceps tenodesis (OSPBT) for the management of long head of the biceps tendon (LHBT) pathology. While patients had similar 1-year biceps muscle strength and pain, longer-term functional outcomes are unknown. Purpose: To directly compare clinical outcomes of ASPBT versus OSPBT with interference screw fixation, distal to the bony bicipital groove, at a minimum of 2 years’ follow-up. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A total of 85 patients undergoing biceps tenodesis (BT) for LHBT disease were randomized into the ASPBT or OSPBT group. Both techniques utilized polyether ether ketone inference screws for tenodesis fixation. Patients completed American Shoulder and Elbow Surgeons (ASES), Constant subjective, and Single Assessment Numeric Evaluation (SANE) questionnaires preoperatively and again at 6 months, 12 months, and at the final follow-up at a minimum of 24 months. Results: A total of 73 patients (37/42 randomized to ASPBT [88%]; 36/42 randomized to OSPBT [86%]) with a mean age of 50.4 ± 10.3 years and a mean body mass index of 29 ± 7.9 were included in clinical outcome analyses. The mean final follow-up was 2.9 years (ASPBT, 3 years; OSPBT, 2.8 years [range 2-5.2 years]). Comparison of demographic characteristics and intraoperative findings showed no significant differences in age, sex, concomitant procedures, and rotator cuff disease. No statistically significant differences in the ASES (P = .25), Constant subjective (P = .52), and SANE scores (P = .61) were found at the final follow-up. Clinical outcomes scores showed no significant improvement from a mean of 12.6 months to the final follow-up at 34.5 months (ASPBT: ASES, P = .43; Constant, P = .25; SANE, P = .45 vs OSPBT: ASES, P = .65; Constant, P = .78; SANE, P = .70). No patients required revision of BT in either group. Conclusion: This study reported a minimum of 2-year follow-up of patients undergoing ASPBT or OSPBT, utilizing the same interference screw technique, for the management of LHBT pathology in the setting of concomitant shoulder procedures. There were no significant differences in patient-reported outcomes and complication rates found at any time point. Registration: NCT02192073 (ClinicalTrials.gov identifier).
The burden associated with, and management of, difficult-to-treat depression in patients under specialist psychiatric care in the United Kingdom

Background: Major depressive disorder (MDD) is common and often has sub-optimal response to treatment. Difficult-to-treat depression (DTD) is a new concept that describes ‘depression that continues to cause significant burden despite usual treatment efforts’. Aims: To identify patients with likely DTD in UK secondary care and examine demographic, disease and treatment data as compared with ‘non-DTD’ MDD patients. Methods: Anonymised electronic health records (EHRs) of five specialist mental health National Health Service (NHS) Trusts in the United Kingdom were analysed using a natural language processing model. Data on disease characteristics, comorbidities and treatment histories were extracted from structured fields and using natural language algorithms from unstructured fields. Patients with MDD aged ⩾18 years were included in the analysis; those with presumed DTD were identified on the basis of MDD history (duration and recurrence) and number of treatments prescribed. Results: In a sample of 28,184 patients with MDD, 19% met criteria for DTD. Compared to the non-DTD group, patients with DTD were more likely to have severe depression, suicidal ideation, and comorbid psychiatric and/or physical illness, as well as higher rates of hospitalisation. They were also more likely to be in receipt of unemployment and sickness/disability benefits. More intensive treatment strategies were used in the DTD group, including higher rates of combination therapy, augmentation, psychotherapy and electroconvulsive therapy. Conclusion: This study demonstrates the feasibility of identifying patients with probable DTD from EHRs and highlights the increased burden associated with MDD in these patients.
[Pain in hospitalized pediatric patients in a third-level healthcare institution].

In the hospital setting, pediatric patients can present painful conditions or undergo procedures that generate pain, therefore, recognizing their existence and carrying out a clinical approach to it should be a priority in health care teams. OBJECTIVE To characterize the pain and its clinical-therapeutic approach in hospitalized patients in the general ward of a tertiary pediatric healthcare institution. PATIENTS AND METHOD An observational, cross-sectional, and descriptive study conducted between August and October 2019. 187 patients were included. Study variables were sex, reason for hospita lization, treating specialty, chronic, current, and in the last 24 hours pain, intensity, maximum cause of pain, and analgesic prescription. The FLACC (Face, Legs, Activity, Cry, Consolability) scale was used in children aged between two months and three years, the revised Faces Pain Scale in children between four and eight years of age, and the self-reported Visual Analogue Scale was used in children from nine years of age onwards. After data analysis with descriptive statistics, differences between groups were calculated with the Chi-square test for qualitative variables, and non-parametric tests for comparison of groups with ordinal variables. RESULTS 10.7% of the patients had chronic pain, without differences according to sex (p = 0.713). The prevalence of pain at the time of the evaluation was 38.5%, without differences according to sex (p = 0.419). Patients admitted for surgery and trau ma had a higher prevalence of pain (p = 0.034) and 53.5% of the children had an analgesic prescrip tion. CONCLUSION the prevalence of pain in the hospitalized pediatric patients is high. Additionally, high use of non-opioid analgesia and a low prescription of opioid analgesics in the pediatric sphere is reported for the usual management of moderate and severe intensity pain.
Effectiveness of the conservation areas on the Mornington Peninsula for the common resident shorebird species using citizen science data

Conservation areas are critical for biodiversity conservation, but few citizen science studies have evaluated their efficiency. In the absence of thorough survey data, this study assessed which species benefit most from conservation areas using citizen science bird counts extracted from the Atlas of Living Australia. This was accomplished by fitting temporal models using citizen science data taken from ALA for the years 2010–2019 using the INLA approach. The trends for six resident shorebird species were compared to those for the Australian Pied Oystercatcher, with the Black-fronted Dotterel, Red-capped Dotterel, and Red-kneed Dotterel exhibiting significantly steeper increasing trends. For the Black-fronted Dotterel, Masked Lapwing, and Red-kneed Dotterel, steeper rising trends were recorded in conservation areas than in other locations. The Dotterel species’ conservation status is extremely favourable. This study demonstrates that, with some limits, statistical models can be used to track the persistence of resident shorebirds and to investigate the factors affecting these data.
Experiences with Telehealth for Outpatient Palliative Care: Findings from a Mixed-Methods Study of Patients and Providers across the United States.

Background: The COVID-19 pandemic introduced a rapid adoption and scale-up of telehealth for palliative care services in the United Sates. Objectives: To examine and compare in-person versus telehealth experience among outpatient palliative care programs and patients. Design: Mixed-methods study (1) comparing patient experience survey data received between September 2020 and February 2021 from patients who received only in-person care versus those who received only telehealth and (2) qualitative interviews with outpatient palliative care providers. Data for this study were collected as part of a larger effort to develop quality measures for outpatient palliative care in the United States. Setting/Subjects: Outpatient palliative care patients and programs. Measurements: We measured patients' experiences of "feeling heard and understood" by their palliative care provider and team and their overall rating of their provider and team. We also conducted in-depth semistructured interviews with 47 palliative care providers across 25 outpatient palliative care programs. Results: Of 1753 patient experience surveys, 26% reflected telehealth only versus 74% in-person only. Patients in both groups reported highly positive experiences; there were no differences in "feeling heard and understood" or the overall ratings of the provider and team between the telehealth-only and in-person-only groups. Palliative care program leaders described the benefits and challenges of telehealth, including increased efficiency, the ability to incorporate family members, and challenges conducting a physical examination. Conclusion: Data from this study provide preliminary evidence of overall positive experiences of telehealth for outpatient palliative care among patients and providers; future research is needed to examine the sustainability of telehealth for palliative care.
The sub-acute toxicity of kavalactone in rats: a study of the effect of oral doses and the mechanism of toxicity in combination with ethanol

Abstract Kava is a herbal supplement and beverage made from the Piper methysticum plant, which is known for its recreational use as a mood enhancer, relaxation, as well as pain relief for centuries. Kava is widely used among alcoholics, but it is dangerous and potentially fatal. The objectives of this study were to examine the sub-acute toxicity effects of different doses of 70% kavalactone (KL) in rats by oral application, as well as to elucidate the mechanisms of toxicity alone and in combination with ethanol (EtOH). The most common side effects observed were abnormal breathing, ataxia, lethargy, loss of appetite, indigestion, and loss of coordination, especially in the 800 mg/kg bw, po bodyweight dosage of kava treatment group alone, and in combination with EtOH. In the sub-acute study, there were dose-related decreases in body weight, feed intake, and water consumption rates. Gross and histopathological findings revealed that the liver was abnormal in color, size, consistency, and the weight significantly increased at a dose of 800 mg/kg bw, po, with KL alone and a greater increase in combination with EtOH. Hepatocellular hypertrophy (HP) and necrosis with Kupffer cells hyperplasia were observed in the periacinar zone of all rats dosed with KL (800 mg/kg bw, po) alone, and extensive changes were observed in combination with EtOH. The periportal (Z1) and mid-zonal (Z2) areas of hepatocytes were less affected as compared to the periacinar zone. These results demonstrate that EtOH exacerbated the sedative and hypnotic activity of KL, and markedly increased toxicity. The histopathological results supported the clinical and biochemical findings and the severity of hepatic damage in a dose-dependent manner.
Features of ophthalmic, magnetic resonance imaging, and histopathology of a feline case of idiopathic sclerosing orbital pseudotumor

Abstract In the present report, we describe a case of sclerosing orbital pseudotumor in an 11‐year‐old castrated male American Shorthair cat. Ophthalmic exam showed lagophthalmos, retracted right upper eyelid, and resistant to retropulsion in his right eye. Under magnetic resonance imaging (MRI) scans, increased volume of the extraocular muscles (EOMs) of the right eye was prominent. Immunosuppressive dosage of prednisolone partially ameliorated the clinical signs, but some clinical signs were still gradually progressive or persistent. In the second MRI scan, decreased diameter of the thickened right extraocular muscles was found. After the third MRI scan, enucleation of the right eye was performed due to substantial adverse effects of systemic steroid therapy. Histopathological examination revealed no evidence of neoplastic transformation nor infection. Feline restrictive orbital myofibroblastic sarcoma (FROMS) was therefore excluded, suggesting unknown causes of extensive fibrotic changes in the right orbit of the affected cat.
Identifying misconduct-committing officer crews in the Chicago police department

Explanations for police misconduct often center on a narrow notion of “problem officers,” the proverbial “bad apples. ” Such an individualistic approach not only ignores the larger systemic problems of policing but also takes for granted the group-based nature of police work. Nearly all of police work is group-based and officers’ formal and informal networks can impact behavior, including misconduct. In extreme cases, groups of officers (what we refer to as, “crews”) have even been observed to coordinate their abusive and even criminal behaviors. This study adopts a social network and machine learning approach to empirically investigate the presence and impact of officer crews engaging in alleged misconduct in a major U.S. city: Chicago, IL. Using data on Chicago police officers between 1971 and 2018, we identify potential crews and analyze their impact on alleged misconduct and violence. Results detected approximately 160 possible crews, comprised of less than 4% of all Chicago police officers. Officers in these crews were involved in an outsized amount of alleged and actual misconduct, accounting for approximately 25% of all use of force complaints, city payouts for civil and criminal litigations, and police-involved shootings. The detected crews also contributed to racial disparities in arrests and civilian complaints, generating nearly 18% of all complaints filed by Black Chicagoans and 14% of complaints filed by Hispanic Chicagoans.
Exploring COVID-19 Vaccine Hesitancy Amongst Black Americans: Contributing Factors and Motivators

Purpose To determine reasons for hesitancy towards COVID-19 vaccination and motivators to increase COVID-19 vaccine uptake among Black Americans. Design Mixed-methods. Setting Individual interviews in March-April 2021 Participants Black adults (20-79 years) who attended a church in Boston, MA and identified as “vaccine hesitant” (n = 18). Methods Individual in-depth Zoom interviews to elicit participant views on vaccines in general, specific reasons for COVID-19 vaccine hesitancy, and trusted sources of information. Participants were also asked about possible motivators that could increase COVID-19 vaccine uptake. Transcripts were de-identified and analyzed for major themes using an inductive approach. Results Analysis included 18 complete interviews. Lack of trust in the government, healthcare, or pharmaceutical companies (n = 18), rushed development (n = 14), fear of side effects (n = 12), history of medical mistreatment (n = 12), and a perception of low risk of disease (n = 9) were the top-cited reasons for COVID-19 vaccine hesitancy. Motivators likely to increase COVID-19 vaccine uptake included more data (n = 17), friends and family getting vaccinated (not celebrities) (n = 11), and increased opportunities that come along with being vaccinated (n = 8). Conclusion There were many reasons for COVID-19 vaccine hesitancy, as reported by participants who were all Black Americans in the Boston area. The public health challenge of increasing vaccine uptake in the Black community is nuanced and intervention efforts may be more successful if delivered by trusted members of the community and tailored to the needs of individuals.
Subacromial space measured by ultrasound imaging in asymptomatic subjects and patients with subacromial shoulder pain: an inter-rater reliability study

ABSTRACT Background Acromiohumeral distance (AHD) and supraspinatus tendon thickness (STT) measured by ultrasound (US) can be combined in the occupation ratio (OR). Inter-rater reliability on these subacromial measures depends on the US experience of raters and on the subject status, differing between asymptomatic or patients with subacromial shoulder pain (SSP). Objective To evaluate inter-rater reliability between two raters with different US experience (experienced examiner and novice examiner). Methods In total, 20 asymptomatic subjects (controls) and 21 patients with SSP were examined on one shoulder. Inter-rater reliability was evaluated with intraclass correlation coefficient (ICC). Results ICC for controls was good for AHD at rest and at 60° (0.76–0.77), moderate for STT and AHD at 60° with weights (0.53–0.72), while OR was poorly reliable (below 0.44). ICC for SSP was moderate for AHD at rest and at 60°, STT, OR at rest and at 60° (0.52–0.74) and poor for AHD at 60° with weights and OR at 60° with weights (0.33–0.36). Bland–Altman plots showed systematic bias. Conclusion Inter-rater reliability varied largely from poor to good between two examiners with different US experience. Clinicians might use the US as additional tool for detecting the subacromial structures, but a structured training including also symptomatic subjects is suggested. Researchers may further investigate the OR in matched case–control studies, and an overall agreement phase is recommended before starting the inter-rater reliability phase.
