RESUMO

Grief is highly prevalent in adolescents, however, there have been no studies investigating internet delivered cognitive behaviour therapy for grief in adolescents (ICBT-G-A). In this paper, the co-design of an unguided ICBT-G-A intervention is described, and a protocol outlined for a pilot randomised controlled trial of the intervention. Participants will be randomised to the intervention (delivered via eight modules over a four-week period) or a four-week waitlist control. Intervention participants will complete a follow-up assessment at one-month post-intervention (eight weeks from the pre-intervention assessment). The intervention outcomes assessed at pre-intervention, post-intervention and follow-up include wellbeing and symptoms of anxiety, depression, post-traumatic stress, and prolonged grief. User feedback on experiences and acceptability of the intervention will be sought and feasibility assessed via programmatic data on recruitment and attrition.

RESUMO

BACKGROUND: Perfectionism dimensions, including perfectionistic strivings and perfectionistic concerns, have a significant positive association with psychopathology. Clinical perfectionism is defined as when an individual's self-esteem is excessively reliant on meeting high standards despite negative consequences. Numerous studies have found that higher perfectionistic concerns correlate with lower self-esteem; however, evidence for the association with perfectionistic strivings has been mixed. AIMS: The focus of this systematic review and meta-analysis was to inform theoretical understanding of the relationships between perfectionism dimensions and self-esteem in adults. METHOD: A systematic literature search was conducted in Medline, PsycINFO, PsychARTICLES, ProQuest Central, and Scopus on 31 May 2023. RESULTS: There were 83 articles included, with 32,304 participants (Mage=∼24.66 years). There was a significant negative moderate pooled association between self-esteem and perfectionistic concerns, r=-.42, 95% CI [-0.47 to -0.38]. A significant negligible positive pooled association was found between self-esteem and perfectionistic strivings, r=.06, 95% CI [0.01 to 0.11]. Results indicate higher perfectionistic concerns is associated with lower self-esteem, providing indirect support for the cognitive-behavioural model of clinical perfectionism. CONCLUSIONS: Future research should compare cognitive behaviour therapy for perfectionism to treatments for low self-esteem on outcomes of perfectionistic concerns and psychopathology.

RESUMO

Feline upper respiratory tract infections (URI) are of concern, especially in animal shelters. This scoping review identifies epidemiological literature on URI as caused by feline herpesvirus (FHV), feline calicivirus (FCV), Chlamydia felis, Mycoplasma felis and Bordetella bronchiseptica. Four databases were searched, studies were screened, and data were extracted on a standardised template. We described patterns in spatial locations of the studies, the range of pathogens and diagnostic tests, cohort characteristics and the findings of risk factor analyses. A total of 90 articles were selected for final data extraction. There was diversity in sampling methods, precluding quantitative meta-analysis of prevalence reports. FHV was most frequently studied (n = 57/90). The most popular sampling site was conjunctival swabbing (n = 43). Most studies (n = 57) used polymerase chain reaction (PCR) to confirm diagnosis. Approximately one-third (n = 32/90) of the studies included sheltered felines. This review explores the current state of knowledge on the epidemiology and risk factors of feline URI. Assessing the impact of risk factors has the potential to alleviate the severity of disease, especially in shelters; however, the results were not easily pooled as the studies used inconsistent approaches. We present recommendations for ongoing epidemiological research on feline URI to provide a more structured framework and define research questions for future systematic reviews.

RESUMO

Clinical perfectionism, self-esteem, mood intolerance, and interpersonal difficulties are associated with eating disorder symptoms in clinical samples. The aim of the current study was to test a model including clinical perfectionism, self-esteem, mood intolerance, and interpersonal difficulties to understand eating disorder symptoms in an adolescent community sample. Adolescents (N = 446, M age = 16.25 years, SD = 1.64; 74.2% female) completed measures of clinical perfectionism, self-esteem, mood intolerance, interpersonal difficulties, and eating disorder symptoms. Path analysis indicated clinical perfectionism, self-esteem, mood intolerance, and interpersonal difficulties were all directly associated with symptoms of eating disorders, and that clinical perfectionism was indirectly associated with eating disorders through self-esteem, mood intolerance, and interpersonal difficulties. The results indicate the cognitive-behavioural model of eating disorders can be applied to adolescents in the community with symptoms of eating disorders. Directional causality between constructs should be established to understand whether increased clinical perfectionism, and reduced self-esteem, mood intolerance, and interpersonal difficulties are vulnerabilities to the development and maintenance of eating disorders.

RESUMO

The rapid emergence of antimicrobial resistance (AMR) in Campylobacter has reinforced its status as a foodborne pathogen of significant public health concern. Resistant Campylobacter is typically transferred to humans via the consumption of contaminated animal products, particularly poultry. The genes associated with antimicrobial resistance in Campylobacter spp. are poorly understood. To address this knowledge gap, we conducted a prevalence survey of AMR Campylobacter across 84 chicken farms in two districts of Bangladesh. Pooled cloacal swabs were collected from chickens and underwent bacteriological testing for Campylobacter spp. with PCR confirmation. Antimicrobial susceptibility was tested against 14 antibiotics by disk diffusion method, and 12 resistance genes were screened in Campylobacter-positive isolates using multiplex PCR. A total of 34 (40.5%) farms were Campylobacter-positive of which 73.5% of isolates were resistant to at least 10 antibiotics. The antimicrobial susceptibility results indicate a high level of resistance against streptomycin (97.1%), clindamycin (97.1%), ampicillin (94.1%), tetracycline (94.1%), erythromycin (91.2%), ciprofloxacin (88.2%), nalidixic acid (85.3%), and imipenem (82.4%), and comparatively a low frequency of resistance to chloramphenicol (47.1%), ceftazidime (44.1%), and colistin (35.3%). Multidrug-resistant (MDR) and extensively drug-resistant Campylobacter were identified in 97.1%, and 50% of isolates, respectively. Ten resistance genes were identified including blaTEM (in 97.1% of isolates), strA-strB (85.9%), tetA (70.6%), tetB (32.4%), qnrS (23.5%), blaCTX-M-1 (20.6%), qnrB (20.6%), blaSHV (8.8%), aadB (5.9%), and qnrA (2.9%). Our findings demonstrate that resistance to ampicillin, tetracycline, and ceftazidime in Campylobacter isolates was significantly (p ≤ 0.05) associated with the presence of blaTEM, tetA, and blaSHV genes, respectively. The high rates of AMR in Campylobacter isolates from our study are not surprising given the liberal use of antimicrobials and incomplete biosecurity provisions on farms. Of particular concern are resistance rates to those classes of antibiotics that should be reserved for human use (azithromycin, ciprofloxacin, and colistin). AMR was more prevalent in chicken farms that used multiple antibiotics, engaged in prophylactic treatment of the birds, and improperly disposed of antibiotic packages. The high prevalence of MDR in chicken-derived Campylobacter isolates from the different regions of our study reinforces the need for more prudent use of antimicrobial compounds in Bangladeshi chicken farms.

RESUMO

BACKGROUND: There is a strong association between perfectionism and eating disorders. In a cognitive-behavioural model of compulsive exercise it has been suggested there are reciprocal associations between perfectionism, eating disorder pathology, and compulsive exercise. No study has examined if there is an indirect association between perfectionism and compulsive exercise through eating disorder pathology, which would inform a preliminary understanding of the cognitive-behavioural model of compulsive exercise. METHODS: The sample included 301 adolescent females diagnosed with eating disorders (age M = 14.89, SD = 0.85, range 13-17). We tested models of direct and indirect associations of compulsive exercise in the relationship between perfectionism and eating disorder pathology, and direct and indirect associations of eating disorder pathology in the relationship between compulsive exercise and perfectionism. RESULTS: Perfectionism was directly associated with eating disorder pathology and compulsive exercise. Perfectionism was indirectly associated with eating disorder pathology through compulsive exercise. Perfectionism also had an indirect association with compulsive exercise through eating disorder pathology. DISCUSSION: The findings suggest it would be useful for future prospective research to examine the cognitive-behavioural model of compulsive exercise in adolescents with eating disorders. Compulsive exercise and perfectionism may be useful targets for future research to improve eating disorder treatment. Level of evidence Level V: Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

RESUMO

Perfectionism is a transdiagnostic process associated with depression, anxiety, and obsessive-compulsive disorder (OCD). The focus of this systematic review and meta-analysis was to examine evidence for the association between perfectionistic strivings and perfectionistic concerns with symptoms of depression, general anxiety, social anxiety, task anxiety, and OCD in adults. A total of 416 studies were included, with 113,118 participants aged 17 to 90 years (M = 23.83). Perfectionistic concerns had significant medium correlations with anxiety, OCD and depressive symptoms (pooled r = .38 to .43). Perfectionistic strivings had significant, small correlations with OCD, depression and all anxiety outcomes (pooled r = .10 to .21), except social anxiety where there was no association. Results demonstrate perfectionistic concerns have a stronger relationship with psychological distress than perfectionistic strivings, but strivings are significantly related to distress. Future research should examine the causal relationships between perfectionism dimensions and psychopathology.

RESUMO

BACKGROUND: Perfectionism is significantly associated with symptoms of eating disorders in adolescents. Studies to date have not examined parent-supported CBT for perfectionism in eating disorders (CBT-P-ED). We co-designed the treatment and conducted a feasibility trial. METHODS: Eight parents of adolescents with eating disorders (M age = 48.75 years, 100% female) engaged in three co-design workshops to create a parent-supported CBT-P-ED self-help intervention. A further 10 parents (M age 41.8 years, 50% female) and their adolescent offspring (n = 10, M age 15.4 years, 60% female, 50% with self-reported diagnosis of anorexia nervosa) participated in a feasibility trial and provided feedback on the intervention. RESULTS: The parents who engaged in the co-design workshops suggested several areas to optimise the perfectionism intervention, including using plain language, the impact of parental perfectionism, how to engage with their adolescent in treatment and the importance of increasing eating disorder specific material. Feedback from the feasibility trial suggested that the intervention was acceptable and feasible with 100% of parents and adolescents saying it was useful, and no attrition. CONCLUSIONS: Parent-supported CBT-P-ED appears to be feasible. Future research is now required in a randomised controlled trial.


It has been repeatedly demonstrated that perfectionism can contribute to a variety of health issues. Perfectionism is a process centered on intense self-pressure to meet high standards, which has a significant impact on how an individual views themselves. Perfectionism is more prevalent in individuals with eating disorders than in those without it. There is a strong link between perfectionism and the onset of eating disorders, as well as an increase in disordered eating symptoms and a lower rate of recovery. There is currently no treatment available that addresses perfectionism in both parents and young people. The aim of the project was to work with parents and carers to co-design a parent-supported self-help program for young people that addresses perfectionism in eating disorders. We conducted three co-design workshops, followed by a four-week feasibility study to determine suitability and feedback on the intervention. The goal was to develop an intervention which can offer caregivers and young people easily available support that may aid in their understanding of perfectionism. It is hoped that by addressing perfectionism in young people with eating disorders, this approach will help them recover and thrive.

RESUMO

Perfectionism is a transdiagnostic process contributing to the onset and maintenance of anxiety, obsessive-compulsive disorder (OCD) and depression. The aim of this systematic review and meta-analysis was to examine the association between perfectionism, and symptoms of anxiety, OCD and depression among young people aged 6-24 years. A systematic literature search retrieved a total of 4,927 articles, with 121 studies included (Mpooled age = ~17.70 years). Perfectionistic concerns demonstrated significant moderate pooled correlations with symptoms of anxiety (r = .37-.41), OCD (r = .42), and depression (r = .40). Perfectionistic strivings demonstrated significant, small correlations with symptoms of anxiety (r = .05) and OCD (r = .19). The findings highlight the substantial link between perfectionistic concerns and psychopathology in young people, and to a smaller extent perfectionistic strivings, anxiety, and OCD. The results indicate the importance of further research on early intervention for perfectionism to improve youth mental health.

RESUMO

Aim: Our aim was to examine how code status orders for patients hospitalized with COVID-19 changed over time as the pandemic progressed and outcomes improved. Methods: This retrospective cohort study was performed at a single academic center in the United States. Adults admitted between March 1, 2020, and December 31, 2021, who tested positive for COVID-19, were included. The study period included four institutional hospitalization surges. Demographic and outcome data were collected and code status orders during admission were trended. Data were analyzed with multivariable analysis to identify predictors of code status. Results: A total of 3615 patients were included with full code (62.7%) being the most common final code status order followed by do-not-attempt-resuscitation (DNAR) (18.1%). Time of admission (per every six months) was an independent predictor of final full compared to DNAR/partial code status (p = 0.04). Limited resuscitation preference (DNAR or partial) decreased from over 20% in the first two surges to 10.8% and 15.6% of patients in the last two surges. Other independent predictors of final code status included body mass index (p < 0.05), Black versus White race (0.64, p = 0.01), time spent in the intensive care unit (4.28, p = <0.001), age (2.11, p = <0.001), and Charlson comorbidity index (1.05, p = <0.001). Conclusions: Over time, adults admitted to the hospital with COVID-19 were less likely to have a DNAR or partial code status order with persistent decrease occurring after March 2021. A trend toward decreased code status documentation as the pandemic progressed was observed.

RESUMO

Aim: Our aim is to characterize code status documentation for patients hospitalized with novel coronavirus 2019 (COVID-19) during the first peak of the pandemic, when prognosis, resource availability, and provider safety were uncertain. Methods: This retrospective cohort study was performed at a single tertiary academic medical center. Adult patients admitted between March 1, 2020 and October 31, 2020 who tested positive for COVID-19 were included. Demographic and hospital outcome data were collected. Code status orders during this admission and prior admissions were trended. Data were analyzed with multivariable analysis to identify predictors of code status choice. Results: A total of 720 patients were included. The majority (70%) were full code and 12% were in do-not-attempt resuscitation (DNAR) status on admission; by discharge, 20% were DNAR. Age (p < 0.001), time in the intensive care unit (ICU) (p < 0.001), and having Medicaid (p = 0.04) compared to private insurance were predictors of DNAR. Fourteen percent had no code status order. Older age (p < 0.001), time in the ICU (p = 0.01), and admission to a teaching service (p < 0.001) were associated with having an order. Of patients with a prior admission (n = 227), 33.5% previously had no code status order and 44.5% had a different code status for their COVID-19 admission. Of those with a change, most transitioned to less aggressive resuscitation preferences. Conclusions: Most patients hospitalized with COVID-19 in our study elected to be full code. Almost half of patients with prepandemic admissions had a different code status during their COVID-19 admission, with a trend toward less aggressive resuscitation preference.

RESUMO

Three commercially available integrated rapid DNA instruments were tested as a part of a rapid DNA maturity assessment in July of 2018. The assessment was conducted with sets of blinded single-source reference samples provided to participants for testing on the individual rapid platforms within their laboratories. The data were returned to the National Institute of Standards and Technology (NIST) for review and analysis. Both FBI-defined automated review (Rapid DNA Analysis) and manual review (Modified Rapid DNA Analysis) of the datasets were conducted to assess the success of genotyping the 20 Combined DNA Index System (CODIS) core STR loci and full profiles generated by the instruments. Genotype results from the multiple platforms, participating laboratories, and STR typing chemistries were combined into a single analysis. The Rapid DNA Analysis resulted in a success rate of 80% for full profiles (85% for the 20 CODIS core loci) with automated analysis. Modified Rapid DNA Analysis resulted in a success rate of 90% for both the CODIS 20 core loci and full profiles (all attempted loci per chemistry). An analysis of the peak height ratios demonstrated that 95% of all heterozygous alleles were above 59% heterozygote balance. For base-pair sizing precision, the precision was below the standard 0.5 bp deviation for both the ANDE 6C System and the RapidHIT 200.

RESUMO

INTRODUCTION: Pancreatic trauma results in high morbidity and mortality, in part caused by the delay in diagnosis and subsequent organ dysfunction. Optimal operative management strategies remain unclear. We therefore sought to determine CT accuracy in diagnosing pancreatic injury and the morbidity and mortality associated with varying operative strategies. METHODS: We created a multicenter, pancreatic trauma registry from 18 Level 1 and 2 trauma centers. Adult, blunt or penetrating injured patients from 2005 to 2012 were analyzed. Sensitivity and specificity of CT scan identification of main pancreatic duct injury was calculated against operative findings. Independent predictors for mortality, adult respiratory distress syndrome (ARDS), and pancreatic fistula and/or pseudocyst were identified through multivariate regression analysis. The association between outcomes and operative management was measured. RESULTS: We identified 704 pancreatic injury patients of whom 584 (83%) underwent a pancreas-related procedure. CT grade modestly correlated with OR grade (r 0.39) missing 10 ductal injuries (9 grade III, 1 grade IV) providing 78.7% sensitivity and 61.6% specificity. Independent predictors of mortality were age, Injury Severity Score (ISS), lactate, and number of packed red blood cells transfused. Independent predictors of ARDS were ISS, Glasgow Coma Scale score, and pancreatic fistula (OR 5.2, 2.6-10.1). Among grade III injuries (n = 158, 22.4%), the risk of pancreatic fistula/pseudocyst was reduced when the end of the pancreas was stapled (OR 0.21, 95% CI 0.05-0.9) compared with sewn and was not affected by duct stitch placement. Drainage alone in grades IV (n = 25) and V (n = 24) injuries carried increased risk of pancreatic fistula/pseudocyst (OR 8.3, 95% CI 2.2-32.9). CONCLUSION: CT is insufficiently sensitive to reliably identify pancreatic duct injury. Patients with grade III injuries should have their resection site stapled instead of sewn and a duct stitch is unnecessary. Further study is needed to determine if drainage alone should be employed in grades IV and V injuries. LEVEL OF EVIDENCE: Epidemiologic/Diagnostic study, level III.

RESUMO

Rapid DNA platforms are fully integrated systems capable of producing and analyzing short tandem repeat (STR) profiles from reference sample buccal swabs in less than two hours. The technology requires minimal user interaction and experience making it possible for high quality profiles to be generated outside an accredited laboratory. The automated production of point of collection reference STR profiles could eliminate the time delay for shipment and analysis of arrestee samples at centralized laboratories. Furthermore, point of collection analysis would allow searching against profiles from unsolved crimes during the normal booking process once the infrastructure to immediately search the Combined DNA Index System (CODIS) database from the booking station is established. The DNAscan/ANDE™ Rapid DNA Analysis™ System developed by Network Biosystems was evaluated for robustness and reliability in the production of high quality reference STR profiles for database enrollment and searching applications. A total of 193 reference samples were assessed for concordance of the CODIS 13 loci. Studies to evaluate contamination, reproducibility, precision, stutter, peak height ratio, noise and sensitivity were also performed. The system proved to be robust, consistent and dependable. Results indicated an overall success rate of 75% for the 13 CODIS core loci and more importantly no incorrect calls were identified. The DNAscan/ANDE™ could be confidently used without human interaction in both laboratory and non-laboratory settings to generate reference profiles.

RESUMO

BACKGROUND: The genes for PFN1 and TMSB4 are both highly expressed in oral tissue and both encode actin monomer binding proteins thought to play a role in cell motility and possibly other crucial parts of tumor progression. METHODS: Oral brush cytology of epithelium from oral squamous cell carcinoma (OSCC) was used to measure PFN1 and TMSB4 mRNA in OSCC, while immunohistochemical analysis of tissue was used to check protein levels. RESULTS: High but variable expression of mRNAs encoding these two proteins was observed suggesting they may contribute to tumor characteristics in a subset of OSCCs. Both proteins were highly expressed in normal appearing basal epithelium, in the cytoplasm, and perinuclear area, while expression was minimal in upper epithelial layers. In OSCCs, expression of these proteins varied. In tumors classified as later stage, based on size and/or lymph node involvement, PFN1 levels were lower in tumor epithelium. A control gene, KRT13, showed expression in normal differentiated basal and suprabasal oral mucosa epithelial cells and as reported was lost in OSCC cells. CONCLUSION: Loss of PFN1 in tumor cells has been associated with lymph node invasion and metastasis in other tumor types, strengthening the argument that the protein has the potential to be a tumor suppressor in late-stage OSCC.

RESUMO

OBJECTIVES: To determine the outcomes of vascular injury interventions extending below the knee. METHODS: Vascular injury repairs extending below the knee from January 2008 to December 2014 were collected from six American College of Surgeons Level I trauma centers. Demographics, management, and outcomes were collected and analyzed. RESULTS: A total of 194 vascular injuries were identified. The mean age was 33.7 years, with 88.1% male, and 71.1% had blunt injury. Admission systolic blood pressure was less than 90 mm Hg in 10.8%; prehospital tourniquets were used in 5.6%. Median mangled extremity severity score (MESS) was 6.0 [interquartile range, 6]. Imaging used included computed tomography angiography (58.2%) and angiography (7.2%); with 66 (34.0%) proceeding directly to OR based on examination alone. Vascular interventions were conducted primarily by vascular (66.0%) and trauma (25.3%) surgeons at a median time from injury of 8 hours (interquartile range, 7 hours). Initial interventions included graft interposition (57.7%) with saphenous vein (111) or synthetic graft (1), primary repair (14.9%), endovascular stent-graft (1.5%), and patch angioplasty (2.1%). Fasciotomy was performed at initial operation in 41.8%, and for delayed compartment syndrome in 2.1%. Vascular reintervention was required in 20 patients (6.7%) for bleeding (seven patients) or thrombosis (13 patients). There was a higher reintervention rates for thrombosis among interposition grafts with distal anastomotic sites at the below-knee popliteal compared to those extending to the tibioperoneal trunk or distal trifurcation vessels, but this was not significant. (4/60, 6.7% vs. 6/49, 12.2%; p = 0.34). Postintervention amputation rates were significantly higher among interposition grafts extending distal to the popliteal (4/60 [6.7%] vs. 15/49 [30.6%]; p = 0.006). CONCLUSIONS: The management of vascular injuries extending below the knee remains a complex issue of extremity trauma care. The need for delayed amputation is significantly more common when revascularization below the distal popliteal artery is required. LEVEL OF EVIDENCE: Prognostic/epidemiologic study, level III; therapeutic/care management study, level IV.
