ABSTRACT

BACKGROUND: Transcranial direct current stimulation (tDCS) is a non-invasive form of neurostimulation with potential for development as a self-administered intervention. It has shown promise as a safe and effective treatment for obsessive compulsive disorder (OCD) in a small number of studies. The two most favourable stimulation targets appear to be the left orbitofrontal cortex (L-OFC) and the supplementary motor area (SMA). We report the first study to test these targets head-to-head within a randomised sham-controlled trial. Our aim was to inform the design of future clinical research studies, by focussing on the acceptability and safety of the intervention, feasibility of recruitment, adherence to and tolerability of tDCS, and the size of any treatment-effect. METHODS: FEATSOCS was a randomised, double-blind, sham-controlled, cross-over, multicentre study. Twenty adults with DSM-5-defined OCD were randomised to treatment, comprising three courses of clinic-based tDCS (SMA, L-OFC, Sham), randomly allocated and delivered in counterbalanced order. Each course comprised four 20-min 2 mA stimulations, delivered over two consecutive days, separated by a 'washout' period of at least four weeks. Assessments were carried out by raters who were blind to stimulation-type. Clinical outcomes were assessed before, during, and up to four weeks after stimulation. Patient representatives with lived experience of OCD were actively involved at all stages. RESULTS: Clinicians showed willingness to recruit participants and recruitment to target was achieved. Adherence to treatment and study interventions was generally good, with only two dropouts. There were no serious adverse events, and adverse effects which did occur were transient and mostly mild in intensity. Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) scores were numerically improved from baseline to 24 h after the final stimulation across all intervention groups but tended to worsen thereafter. The greatest effect size was seen in the L-OFC arm, (Cohen's d = -0.5 [95% CI -1.2 to 0.2] versus Sham), suggesting this stimulation site should be pursued in further studies. Additional significant sham referenced improvements in secondary outcomes occurred in the L-OFC arm, and to a lesser extent with SMA stimulation. CONCLUSIONS: tDCS was acceptable, practicable to apply, well-tolerated and appears a promising potential treatment for OCD. The L-OFC represents the most promising target based on clinical changes, though the effects on OCD symptoms were not statistically significant compared to sham. SMA stimulation showed lesser signs of promise. Further investigation of tDCS in OCD is warranted, to determine the optimal stimulation protocol (current, frequency, duration), longer-term effectiveness and brain-based mechanisms of effect. If efficacy is substantiated, consideration of home-based approaches represents a rational next step. TRIAL REGISTRATION: ISRCTN17937049. https://doi.org/10.1186/ISRCTN17937049.

ABSTRACT

BACKGROUND: Services for patients with kidney disease underwent radical adaptations in response to the COVID-19 pandemic. We undertook an online national survey of UK kidney centres to understand the nature, range, and degree of variation in these changes and to explore factors contributing to differing practice. METHODS: The survey was designed by a multidisciplinary team of kidney professionals, service users and researchers. It enquired about centre services and staffing, including psychosocial provision, and changes to these in response to the COVID-19 pandemic. Links to the survey were sent to all 68 UK kidney centres and remained active from December 2021 to April 2022, and a revised version to nurses in late 2022 for additional data. Quantitative data were analysed descriptively. Content analysis on free-text responses identified common themes. RESULTS: Analysable responses were received from 41 out of the 68 UK centres (60%), with partial data from an additional 7 (11%). Adaptations were system-wide and affected all aspects of service provision. Some changes were almost universal such as virtual consultations for outpatient appointments, with significant variation in others. Outpatient activity varied from fully maintained to suspended. Many centres reduced peritoneal dialysis access provision but in some this was increased. Centres considered that changes to transplant surgical services and for patients with advanced CKD approaching end-stage kidney disease had the greatest impact on patients. Few centres implemented adjustments aimed at vulnerable and underrepresented groups, including the frail elderly, people with language and communication needs, and those with mental health needs. Communication issues were attributed to rapid evolution of the pandemic, changing planning guidance and lack of resources. Staffing shortages, involving all staff groups particularly nurses, mainly due to COVID-19 infection and redeployment, were compounded by deficiencies in staffing establishments and high vacancy levels. Centres cited three main lessons influencing future service delivery, the need for service redesign, improvements in communication, and better support for staff. CONCLUSION: Kidney centre responses to the pandemic involved adaptations across the whole service. Though some changes were almost universal, there was wide variation in other areas. Exploring the role of centre characteristics may help planning for potential future severe service disruptions.

ABSTRACT

BACKGROUND: Patient experience is a recognized aspect of quality of care for people with chronic kidney disease (CKD), but current patient-reported experience measures (PREMs) only focus on dialysis care. We developed and validated the Kidney PREM to assess patients' experience with renal services in secondary care for any CKD stage or treatment (transplant, haemodialysis and peritoneal dialysis). METHODS: We developed the Kidney PREM in two phases, informed by a multidisciplinary expert group to ensure face validity. We organized three national data collections (2016-8) to investigate item response profiles and to conduct exploratory and confirmatory analyses to assess internal consistency. We also explored content validity in cognitive interviews and evaluated test-retest reliability. Finally, we developed the Kidney PREM Short Form for more frequent measurement of patient experience to inform local service improvements. RESULTS: We analysed 32 959 responses across data collections, with the 2018 collection covering all 71 UK renal centres. The Kidney PREM final version consisted of 38 items grouped into 13 themes, all pertaining to one underlying dimension reflecting the construct of 'patient experience' with high internal consistency (Cronbach's α = 0.94). The Kidney PREM Short Form consisted of 15 items across the same 13 themes. CONCLUSIONS: The Kidney PREM supports the collection of reliable information on patient experience that people with CKD consider relevant, regardless of CKD stage or treatment modality. Kidney PREM data have the potential to guide local and national initiatives to improve patients' experiences with renal services in the UK and other countries.

ABSTRACT

With the onset of the COVID-19 pandemic and the accelerated spread of the SARS-CoV-2 virus came jurisdictional limitations on mobility of citizens and distinct alterations in their daily routines. Confined to their homes, many people increased their overall internet use, with problematic use of the internet (PUI) becoming a potential reason for increased mental health concerns. Our narrative review summarizes information on the extent of PUI during the pandemic, by focusing on three types: online gaming, gambling and pornography viewing. We conclude by providing guidance for mental health professionals and those affected by PUI (with an outline of immediate research priorities and best therapeutic approaches), as well as for the general public (with an overview of safe and preventative practices).

ABSTRACT

Global concern about problematic usage of the internet (PUI), and its public health and societal costs, continues to grow, sharpened in focus under the privations of the COVID-19 pandemic. This narrative review reports the expert opinions of members of the largest international network of researchers on PUI in the framework of the European Cooperation in Science and Technology (COST) Action (CA 16207), on the scientific progress made and the critical knowledge gaps remaining to be filled as the term of the Action reaches its conclusion. A key advance has been achieving consensus on the clinical definition of various forms of PUI. Based on the overarching public health principles of protecting individuals and the public from harm and promoting the highest attainable standard of health, the World Health Organisation has introduced several new structured diagnoses into the ICD-11, including gambling disorder, gaming disorder, compulsive sexual behaviour disorder, and other unspecified or specified disorders due to addictive behaviours, alongside naming online activity as a diagnostic specifier. These definitions provide for the first time a sound platform for developing systematic networked research into various forms of PUI at global scale. Progress has also been made in areas such as refining and simplifying some of the available assessment instruments, clarifying the underpinning brain-based and social determinants, and building more empirically based etiological models, as a basis for therapeutic intervention, alongside public engagement initiatives. However, important gaps in our knowledge remain to be tackled. Principal among these include a better understanding of the course and evolution of the PUI-related problems, across different age groups, genders and other specific vulnerable groups, reliable methods for early identification of individuals at risk (before PUI becomes disordered), efficacious preventative and therapeutic interventions and ethical health and social policy changes that adequately safeguard human digital rights. The paper concludes with recommendations for achievable research goals, based on longitudinal analysis of a large multinational cohort co-designed with public stakeholders.

ABSTRACT

Stormwater best management practices (BMPs) are engineered structures that attempt to mitigate the impacts of stormwater, which can include nitrogen inputs from the surrounding drainage area. The goal of this study was to assess bacterial community composition in different types of stormwater BMP soils to establish whether a particular BMP type harbors more denitrification potential. Soil sampling took place over the summer of 2015 following precipitation events. Soils were sampled from four bioretention facilities, four dry ponds, four surface sand filters, and one dry swale. 16S rRNA gene analysis of extracted DNA and RNA amplicons indicated high bacterial diversity in the soils of all BMP types sampled. An abundance of denitrifiers was also indicated in the extracted DNA using presence/absence of nirS, nirK, and nosZ denitrification genes. BMP soil bacterial communities were impacted by the surrounding soil physiochemistry. Based on the identification of a metabolically-active community of denitrifiers, this study has indicated that denitrification could potentially occur under appropriate conditions in all types of BMP sampled, including surface sand filters that are often viewed as providing low potential for denitrification. The carbon content of incoming stormwater could be providing bacterial communities with denitrification conditions. The findings of this study are especially relevant for land managers in watersheds with legacy nitrogen from former agricultural land use.

ABSTRACT

BACKGROUND: Patients with obsessive-compulsive disorder (OCD) commonly exhibit a range of functional difficulties, presumed linked to neurocognitive changes. Evidence-based first-line treatments have limited effect on improving these cognitive-functional problems. Candidate interventions could be used to augment evidence-based treatments by the multi-professional mental health team. METHODS: A scoping review was performed to identify any intervention with at least one peer-reviewed report of clinical improvement in any of the 13 functional domains of the Cognitive Assessment Instrument of Obsessions and Compulsions (CAIOC-13). Next, an online survey of experts of the International College of Obsessive-Compulsive Spectrum Disorders was conducted. RESULTS: Forty-four studies were identified reporting a positive outcome for 27 different kinds of intervention. Twenty-six experts from 12 different countries, including at least one expert from each continent, completed the opinion survey. Five interventions were identified as 'highly promising', none of which was moderated by rater-related factors, suggesting global applicability. CONCLUSION: Patients with OCD may benefit from a detailed functional assessment, to identify areas of unmet need. A variety of interventions show theoretical promise for treating the complex functional difficulties in OCD as adjuncts to first-line treatments, but the published evidence is weak. Randomised controlled trials are needed to determine the clinical effectiveness of these interventions.HighlightsFunctional-cognitive problems are common in patients with OCD.First-line evidence-based treatments have limited effect on these functionalcognitive difficulties.In our scoping review we found 44 studies reporting of improved clinical outcomes in any of the 13 functional domains of the Cognitive Assessment Instrument of Obsessions and Compulsions (CAIOC-13).An online survey of experts of the International College of Obsessive-Compulsive Spectrum Disorders (ICOCS) was conducted and identified five interventions as "highly promising" candidate treatments for functional-cognitive problems in OCD.Randomised controlled trials are needed to determine the clinical effectiveness of these interventions.

ABSTRACT

The aim of this study was to screen for cardiac disease and report normal echocardiographic variables from a managed population of the African painted dog (Lycaon pictus; APD). The study included six male adult APDs under managed care with no evidence of significant structural cardiac disease. Echocardiography was performed with APD maintained under anesthesia with a combination of midazolam, butorphanol, and inhaled isoflurane. All animals underwent a full physical examination and two-dimensional (2D), M-mode, and Doppler echocardiography using standard views. Left ventricular volumes were calculated using the Simpson's method of discs. Medians with ranges were reported for the echocardiographic variables. No valvular structural abnormalities were noted. Trace mitral regurgitation was documented in five of six APD, trace tricuspid regurgitation in three of six, and mild pulmonic regurgitation in all APD. No aortic regurgitation was noted. Standard M-mode measurements fell within the normal ranges for allometrically scaled M-mode cardiac measurements for normal adult domestic dogs (Canis familiaris). Two-dimensional measurements were comparable with that of domestic dogs with similar body weight. The study demonstrates a similarity in cardiac size and function compared with normal adult domestic dogs and provides baseline echocardiographic variables for investigation of cardiac health in other populations of APDs in the future.

ABSTRACT

Colloid osmotic pressure (COP) is an important component of the forces that manage capillary filtration and is determined by circulating plasma proteins. Patients affected by conditions resulting in hypoproteinemia often suffer severe hemodynamic derangements, including decreased COP. Because chronically debilitated sea turtles (CDT) present with severe hypoproteinemia, the objectives of this study were to 1) determine differences in plasma COP and blood analyte data (packed cell volume [PCV], sodium, chloride, plasma protein fractions) in CDT at admission compared with data from apparently healthy rehabilitated turtles at time of release (HRT) admitted from various stranding causes, and 2) to investigate correlations of COP with these selected blood analytes. COP, PCV, and most plasma protein fractions (excluding pre-albumin and γ-globulins) were significantly lower in CDT upon admission as compared with HRT. Sodium and chloride did not significantly differ between CDT and HRT. A significant increase was observed with PCV and all plasma protein fractions as COP increased. Of all protein fractions tested, albumin contributed the most toward COP (r2 = 0.88, P < 0.001). The results of this study suggest that COP is significantly lower in CDT as compared with HRT, providing insight into the complexity of this critical clinical condition and a small step in advancing the understanding of associated hemodynamic imbalances. Although COP analysis is not readily available as a diagnostic test, this preliminary baseline data suggests that additional research studies are warranted, given the potential for optimization of fluid therapy during rehabilitation of CDT.

ABSTRACT

A 3-yr-old, intact male Matschie's tree kangaroo (Dendrolagus matschiei) was examined for a 1-wk history of intermittent lethargy and tachypnea. An echocardiogram revealed concentric hypertrophy of the left ventricular free wall and interventricular septum. These findings were compared to measurements from healthy Matschie's tree kangaroos, supporting a diagnosis of hypertrophic cardiomyopathy. At the time of publication, the patient has been managed for over 11.5 yr, using a combination of enalapril, furosemide, diltiazem, and diet modifications. Hypertrophic cardiomyopathy should be considered as a differential diagnosis in tree kangaroos exhibiting signs of cardiovascular or respiratory distress. This case represents the first report of antemortem diagnosis and successful management of hypertrophic cardiomyopathy in a Matschie's tree kangaroo.

ABSTRACT

Aphanizomenon flos-aquae (AFA) is the dominant filamentous cyanobacterium that develops into blooms in Upper Klamath Lake, Oregon, each year. During AFA bloom and collapse, ecosystem conditions for endangered Lost River and shortnose suckers deteriorate, thus motivating the need to identify processes that limit AFA abundance and decline. Here, we investigate the relations between AFA and other members of the microbial community (photosynthetic and nonphotosynthetic bacteria and archaea), how those relations impact abundance and collapse of AFA, and the types of microbial conditions that suppress AFA. We found significant spatial variation in AFA relative abundance during the 2016 bloom period using 16S rRNA sequencing. The Pelican Marina site had the lowest AFA relative abundance, and this was coincident with increased relative abundance of Candidatus Sericytochromatia, Flavobacterium, and Rheinheimera, some of which are known AFA antagonists. The AFA collapse coincided with phosphorus limitation relative to nitrogen and the increased relative abundance of Cyanobium and Candidatus Sericytochromatia, which outcompete AFA when dissolved inorganic nitrogen is available. The data collected in this study indicate the importance of dissolved inorganic nitrogen combined with microbial community structure in suppressing AFA abundance.

ABSTRACT

BACKGROUND: Depression is prevalent across the spectrum of Chronic Kidney Disease and associated with poorer outcomes. There is limited evidence regarding the most effective interventions and care pathways for depression in Chronic Kidney Disease. OBJECTIVES: To investigate how depression is identified and managed in adults with Chronic Kidney Disease. DESIGN: Scoping review. METHODS: Systematic search of eight databases with pre-defined inclusion criteria. Data relevant to the identification and/or management of depression in adults with Chronic Kidney Disease were extracted. RESULTS: Of 2147 articles identified, 860 were included. Depression was most identified using self-report screening tools (n = 716 studies, 85.3%), with versions of the Beck Depression Inventory (n = 283, 33.7%) being the most common. A total of 123 studies included data on the management of depression, with nonpharmacological interventions being more frequently studied (n = 55, 45%). Cognitive Behavioural Therapy (n = 15) was the most common nonpharmacological intervention, which was found to have a significant effect on depressive symptoms compared to controls (n = 10). However, how such approaches could be implemented as part of routine care was not clear. There was limited evidence for antidepressants use in people with Chronic Kidney Disease albeit in a limited number of studies. CONCLUSIONS: Depression is commonly identified using validated screening tools albeit differences exist in reporting practices. Evidence regarding the management of depression is mixed and requires better-quality trials of both pharmacological and nonpharmacological approaches. Understanding which clinical care pathways are used and their evidence, may help facilitate the development of kidney care specific guidelines for the identification and management of depression.

ABSTRACT

BACKGROUND: Depression is common in people with chronic kidney disease, yet little is known about how depression is identified and managed as part of routine kidney care. OBJECTIVES: The primary objective was to survey all UK adult kidney centres to understand how depression is identified and managed. A secondary objective was to broadly describe the variability in psychosocial care. DESIGN: Online survey. METHODS: The survey comprised of three sections: (1) general kidney care, (2) psychological provision and (3) social work provision. RESULTS: 48/68 (71%) of centres responded to the general survey with 20 and 13 responses from psychological and social work module respectively. Only 31.4% reported having both in centre psychological and social work practitioners. Three centres reported no access to psychosocial provision. Of the 25 centres who reported on pathways, 36.0% reported having internal pathways for the identification and management of depression. Within services with psychological provision, screening for depression varied across modality/group (e.g., 7.1% in mild/moderate chronic kidney disease vs. 62.5% in kidney donors). Cognitive Behavioural Therapy and Acceptance and Commitment Therapy were the most common interventions offered. Most psychosocial services were aware of the National Institute for Health and Care Excellence guidelines for managing depression in long-term conditions (n = 18, 94.7%) yet few fully utilised (n = 6, 33.3%). Limited workforce capacity was evident. CONCLUSIONS: There is considerable variability in approaches taken to identify and treat depression across UK kidney services, with few services having specific pathways designed to detect and manage depression. Workforce capacity remains a significant issue.

ABSTRACT

Two indirect blood pressure measurement techniques, Doppler (DOP) sphygmomanometry and oscillometry, applied at the ventral coccygeal artery were compared with simultaneous direct blood pressure measurements at the dorsal pedal artery in 10 anesthetized, captive cheetahs (Acinonyx jubatus). The DOP method was moderately accurate, with relatively little bias (mean difference 3.8 mmHg) and 88.6% of the DOP systolic arterial pressure measurements being within 10 mmHg of the direct systolic arterial measurement. With the oscillometric (OM) method, 89.2% of the mean arterial pressure measurements were within 10 mmHg of the direct measurement and had the least bias (mean difference 2.3 mmHg), 80.7% of the systolic measurements were within 10 mmHg of the direct measurement and had the second least bias (mean difference 2.3 mmHg), and 59% of the diastolic measurements were within 10 mmHg of the direct measurement and had significant bias (mean difference 7.3 mmHg). However, DOP showed relatively poor precision (SD 11.2 mmHg) compared with OM systolic (SD 8.0 mmHg), diastolic (SD 8.6 mmHg), and mean (SD 5.7 mmHg). Both techniques showed a linear relationship with the direct technique measurements over a wide range of blood pressures. The DOP method tended to underestimate systolic measurements below 160 mmHg and overestimate systolic measurements above 160 mmHg. The OM method tended to underestimate mean pressures below 160 mm Hg, overestimate mean pressures above 160 mmHg, underestimate systolic pressures below 170 mmHg, overestimate systolic pressures above 170 mmHg, and underestimate diastolic pressures throughout the measured blood pressure range. Indirect blood pressure measurement using the ventral coccygeal artery, particularly when using an OM device for mean and systolic arterial pressure, may be useful in the clinical assessment of cheetahs when monitoring trends over time, but caution should be taken when interpreting individual values.

ABSTRACT

A 19-yr-old intact female variable flying fox (Pteropus hypomelanus) presented with lethargy, behavior changes, and substantial weight loss. Initial clinical pathology revealed hypoglycemia and reduced ionized serum calcium, and imaging, including computed tomography, did not lead to a diagnosis. An adrenocorticotropic hormone (ACTH) stimulation test revealed baseline and post-ACTH cortisol concentrations that were lower than reported normal baseline cortisol concentrations in this species. Treatment with prednisolone resolved the clinical signs and laboratory abnormalities. Repeated attempts to decrease the prednisolone dose caused recurrence of clinical signs and weight loss. Based on diagnostic test results and response to therapy, a diagnosis of atypical hypoadrenocorticism was made.

ABSTRACT

Evidence-based recommendations for performing cardiopulmonary resuscitation (CPR) in domestic species provide a foundation for application to nondomestic species. The exotic and zoo practitioner must consider human safety, species anatomy, physiology, and special techniques for performing CPR. Having the hospital and team prepared and trained for a CPR response can improve outcomes. Basic life support includes various techniques for chest compressions and ventilation support. Advanced life support includes means of intravascular and intraosseous access, rescue drug administration, and consideration of the patient presenting circumstances. Team debriefs and support for mental wellness are useful to optimize performance and maintain team resiliency through CPR events.

ABSTRACT

OBJECTIVE: The anti-GnRH immunotherapeutic product Improvest was administered to intact male large flying foxes (Pteropus vampyrus) under managed care for androgen mitigation, leading to a decrease in agonistic behaviors, falls, and injuries from conspecific attention. ANIMALS: 12 males were included in this study. PROCEDURES: Eleven bats received subcutaneous (SC) Improvest interscapular, and 1 animal received Improvest SC in its leg. Assessments included clinical presentation, treatment, behavior, and urine and fecal glucocorticoid metabolites and testosterone (T5) concentrations. RESULTS: Eleven of the 12 bats developed reactions, which included facial edema, localized irritation, swelling of the head and neck, and pruritus with varying degrees of skin ulceration and subsequent necrosis. Three of the animals required extensive treatments, and the 1 animal who received the injection in its leg was unaffected. Posttreatment, fecal glucocorticoid metabolite and/or T5 values were at or below the nonbreeding season baseline for 3 successive breeding seasons, and there was a reduction in agonistic interactions, falls, and injuries. CLINICAL RELEVANCE: A behavioral characteristic of this species is to focus on areas of irritation that exacerbated the extent of the skin wounds. Some cases required medical, surgical, and behavioral intervention. Large flying foxes may be particularly sensitive to this immunotherapeutic when given subcutaneously in the interscapular region. Despite this reaction, the positive long-term effects on behavior and multiyear reduction of hormones suggest that the use of this immunotherapeutic warrants further investigation, although the results should be taken into consideration with other factors such as handling, treatments, chronicity of lesions.

ABSTRACT

Herpesviruses can be significant reptile pathogens. Herpesviral infection in a wild-caught, male spider tortoise (Pyxis arachnoides) under human care was detected during a routine wellness examination prior to transition between zoologic organizations. The tortoise had no clinical signs of illness. Oral swabs obtained during a physical examination as part of pre-shipment risk mitigation for infectious disease were submitted for consensus herpesvirus PCR assay and sequencing. Based on comparative sequence analysis, the novel herpesvirus identified is a member of the subfamily Alphaherpesvirinae. Studies of herpesviral phylogeny in chelonian species support branching patterns of turtle herpesviruses that closely mirror those of their hosts. The symmetry of these patterns is suggestive of close codivergence of turtle herpesviruses with their host species. The distribution of these viruses in both tortoises and emydids suggests a phylogenetic duplication event in the herpesviruses after host divergence of the Pleurodira and basal to the divergence of Americhelydia. Herpesviral infections have been documented to cause higher morbidity when introduced to aberrant host species, and significant consideration must be given to the presence of herpesviruses in the management of tortoise collections, particularly collections that include various species of testudines.

ABSTRACT

A rescued female manatee was observed expelling a fetal bone from the vulva. The manatee was anesthetized and diagnosed with uterine retention of a fetal skeleton by ultrasound and hysteroscopy. Episiotomy was performed to gain manual access to the vagina and uterus for removal of the skeleton. Second intention healing of the episiotomy site produced excellent results. Rescued female manatees should receive a thorough reproductive tract evaluation since presence of retained fetal tissues might not be evident in blood or hormone analyses. Retention of a whole or partial dead fetus can be life-threatening to manatees, and retained tissues should be removed as early as possible.
