ABSTRACT

The heterogeneity of schizophrenia has been acknowledged for decades because of the diverse presentation of symptoms, illness course, and treatment response noted between individuals diagnosed with the disorder. Cluster analysis has been used as a statistical method to determine whether schizophrenia subgroups might be identified based on symptom heterogeneity. However, there is very limited research examining whether heterogeneity in negative symptoms might be useful in establishing schizophrenia subtypes, particularly research examining newer models of negative symptoms based on five latent constructs including anhedonia, asociality, avolition, blunted affect, and alogia. The Brief Negative Symptom Scale was used to assess the five negative symptoms domains in a sample of 220 outpatients diagnosed with schizophrenia or schizoaffective disorder. Cluster analysis supported a four-cluster solution, comprising clusters of subjects with low negative symptoms (LNS), severe negative symptoms (SNS), and two clusters with moderate negative symptoms, one with predominantly elevated blunted affect (BA) and one with elevated avolition (AV). The LNS, SNS, BA, and AV clusters significantly differed on external validators including clinical characteristics, neurocognition, and functional outcome. Findings suggest that schizophrenia heterogeneity can be parsed according to negative symptom subtypes that have distinct clinical and neuropsychological profiles. Implications for diagnosis and treatment are discussed.

ABSTRACT

Adolescent athletes with attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) experience unique challenges that impact their sport performance, such as making errors due to poor concentration. The current multiple-baseline across behaviors case trial (i.e., positive assertion and negative assertion) is an evaluation of The Optimum Performance Program in Sports in an adolescent athlete diagnosed with ADHD and ODD. Intervention skill sets were targeted sequentially in a virtual format to safeguard against COVID-19 contraction. A battery of psychological measures was administered at baseline, post-intervention, and 1-month follow-up. Results indicated negative and positive assertion skills improved, but only when targeted, and severity of ADHD and ODD symptom severity, general mental health symptoms, and factors interfering with sport performance decreased from pre- to post-intervention and these improvements were maintained at 1-month follow-up. Similar improvements occurred in relationships with coaches, teammates, and family. Treatment integrity and consumer satisfaction were high.

ABSTRACT

Neuropsychologists evaluate children and adults with ADHD to establish a diagnosis, quantify cognitive deficits associated with ADHD and other common comorbid conditions, and provide recommendations for education and vocational planning. Standardized instruments that align with DSM ADHD symptom criteria are recommended for increasing ADHD diagnostic accuracy. This study examined whether a brief DSM-based symptom rating scale would assist in differentiating subtypes of ADHD. Participants were 253 children diagnosed with ADHD-Inattentive (n = 163) or ADHD-Combined (n = 90). Parents completed the Behavior Assessment System for Children, Second Edition (BASC-2) and DSM-IV ADHD Symptom Rating Scale (SRS) as part of a comprehensive evaluation to establish ADHD diagnoses. The SRS displayed expected convergent and discriminant validity with BASC-2 subscales. The diagnostic accuracy of the SRS subscales to differentiate ADHD was also examined and compared with the BASC-2. Results indicated that SRS Impulsivity, SRS Hyperactivity, and BASC-2 Hyperactivity had significantly better classification accuracy than BASC-2 Attention Problems and SRS Inattention, although they did not differ from each other. The SRS produced symptom profiles consistent with ADHD-Inattentive and Combined subtypes with good classification accuracy when differentiating subtypes. Overall, the SRS is an economical measure that can assist in ADHD presentation differentiation when used as a component of ADHD evaluations.

ABSTRACT

BACKGROUND: Urinary incontinence (UI) and lower urinary tract symptoms (LUTS) are commonly experienced by adult patients in hospitals (inpatients). Although peak bodies recommend that health services have systems for optimal UI and LUTS care, they are often not delivered. For example, results from the 2017 Australian National Stroke Audit Acute Services indicated that of the one-third of acute stroke inpatients with UI, only 18% received a management plan. In the 2018 Australian National Stroke Audit Rehabilitation Services, half of the 41% of patients with UI received a management plan. There is little reporting of effective inpatient interventions to systematically deliver optimal UI/LUTS care. OBJECTIVE: This study aims to determine whether our UI/LUTS practice-change package is feasible and effective for delivering optimal UI/LUTS care in an inpatient setting. The package includes our intervention that has been synthesized from the best-available evidence on UI/LUTS care and a theoretically informed implementation strategy targeting identified barriers and enablers. The package is targeted at clinicians working in the participating wards. METHODS: This is a pragmatic, real-world, before- and after-implementation study conducted at 12 hospitals (15 wards: 7/15, 47% metropolitan, 8/15, 53% regional) in Australia. Data will be collected at 3 time points: before implementation (T0), immediately after the 6-month implementation period (T1), and again after a 6-month maintenance period (T2). We will undertake medical record audits to determine any change in the proportion of inpatients receiving optimal UI/LUTS care, including assessment, diagnosis, and management plans. Potential economic implications (cost and consequences) for hospitals implementing our intervention will be determined. RESULTS: This study was approved by the Hunter New England Human Research Ethics Committee (HNEHREC Reference No. 18/10/17/4.02). Preimplementation data collection (T0) was completed in March 2020. As of November 2020, 87% (13/15) wards have completed implementation and are undertaking postimplementation data collection (T1). CONCLUSIONS: Our practice-change package is designed to reduce the current inpatient UI/LUTS evidence-based practice gap, such as those identified through national stroke audits. This study has been designed to provide clinicians, managers, and policy makers with the evidence needed to assess the potential benefit of further wide-scale implementation of our practice-change package.

ABSTRACT

Objective: Despite evidence of social skill deficits in children with ADHD, there is no consensus regarding a social cognitive profile and whether these skills predict behavior. Therefore, a comprehensive battery was used to investigate the relationship between social cognition and behavioral functioning. Method: Children ages 7 to 13 with ADHD (n = 25) and controls (n = 25) completed tests assessing social cognitive domains (affect recognition and theory of mind [ToM]). Parents completed measures of social cognition (pragmatic language ability and empathy), behavioral symptoms, and adaptive functioning. Results: Children with ADHD performed significantly worse on measures of cognitive ToM and affect recognition and received lower ratings of pragmatic language and cognitive empathy than typically developing peers. These domains, particularly pragmatic language, predicted parent ratings of problematic and adaptive behaviors. Conclusion: Results establish a relationship between specific social cognitive abilities and daily functioning, which has implications for treatment.

ABSTRACT

AIMS AND OBJECTIVES: This study aimed to reduce indwelling urinary catheter (IDC) use and duration through implementation of a multifaceted "bundled" care intervention. BACKGROUND: Indwelling urinary catheters present a risk for patients through the potential development of catheter-associated urinary tract infection (CAUTI), with duration of IDC a key risk factor. Catheter-associated urinary tract infection is considered preventable yet accounts for over a third of all hospital-acquired infections. The most effective CAUTI reduction strategy is to avoid IDC use where ever possible and to remove the IDC as early as appropriate. DESIGN: A cluster-controlled pre- and poststudy at a facility level with a phased intervention implementation approach. METHODS: A multifaceted intervention involving a "No CAUTI" catheter care bundle was implemented, in 4 acute-care hospitals, 2 in metropolitan and 2 in rural locations, in New South Wales, Australia. Indwelling urinary catheter point prevalence and duration data were collected at the bedside on 1,630 adult inpatients at preintervention and 1,677 and 1,551 at 4 and 9 months postintervention. This study is presented in line with the StaRI checklist (see Appendix S1). RESULTS: A nonsignificant trend towards reduction in IDC prevalence was identified, from 12% preintervention to 10% of all inpatients at 4 and 9 months. Variability in preintervention IDC prevalence existed across hospitals (8%-16%). Variability in reduction was evident across hospitals at 4 months (between -2% and 4%) and 9 months (between 0%-8%). Hospitals with higher preintervention prevalence showed larger decreases, up to 50% when preintervention prevalence was 16%. Indwelling urinary catheter duration increased as more of the short-term IDC placements were avoided. CONCLUSIONS: Implementation of a multifaceted intervention resulted in reduced IDC use in four acute-care hospitals in Australia. This result was not statistically significant but did reflect a positive trend of reduction. There was a significant reduction in short-term IDC use at 9 months postintervention. RELEVANCE TO CLINICAL PRACTICE: Clinical nurse leaders can effectively implement change strategies that influence patient outcomes. Implementation of the evidence-based "No CAUTI" bundle increased awareness of appropriate indications and provided nurses with the tools to inform decision-making related to insertion and removal of IDCs in acute inpatient settings. Working in partnership with inpatients and the multidisciplinary team is essential in minimising acute-care IDC use.

ABSTRACT

AIMS AND OBJECTIVES: To identify the point prevalence of indwelling urinary catheters (IDCs) in adult inpatients in acute care hospitals, and to describe the indications for IDC insertion based on patient age, gender, specialty and hospital. BACKGROUND: Catheter-associated urinary tract infections (CAUTIs) are preventable healthcare-associated infections. IDC duration is the strongest predictor of CAUTI, and little is known about characteristics of patients who receive an IDC. DESIGN: Two single-day point prevalence surveys collected baseline patient data as part of a larger pre-post control-intervention study. METHODS: Surveys were conducted at four acute care hospitals in NSW, Australia, for all adult patients. Data collection included IDC presence, insertion details and urine culture collection. Point prevalence data were linked with electronically extracted patient demographic data. This study is presented in line with STROBE checklist (See Supplementary File 1). RESULT: Data from 1,630 patients were analysed, with 196 patients (12%) identified as having an IDC on the survey dates. IDC prevalence rates were higher in males (13%) than in females (11%). Critical care had the highest rate of patients with IDCs (42%). Urine cultures were collected in 70 patients with an IDC (43%). CONCLUSIONS: Findings indicated similar rates of IDC use in males and females, and there was no significant difference in age between patients with or without an IDC. However, indication for IDC varied by patient age and gender. High rates of urine culture collection may represent routine collection. RELEVANCE TO CLINICAL PRACTICE: IDC use is found across genders, all age groups and specialties. Nurses should be aware that any of their patients may have an IDC and be particularly aware of certain indications based on patient age and gender. Routine urine culture collection is not advised, and instead, nurses should be guided by clinical decision-making tools.

ABSTRACT

BACKGROUND: In sub-Saharan Africa, rates of sustained HIV virologic suppression remain below international goals. HIV resistance testing, while common in resource-rich settings, has not gained traction due to concerns about cost and sustainability. OBJECTIVE: We designed a randomized clinical trial to determine the feasibility, effectiveness, and cost-effectiveness of routine HIV resistance testing in sub-Saharan Africa. APPROACH: We describe challenges common to intervention studies in resource-limited settings, and strategies used to address them, including: (1) optimizing generalizability and cost-effectiveness estimates to promote transition from study results to policy; (2) minimizing bias due to patient attrition; and (3) addressing ethical issues related to enrollment of pregnant women. METHODS: The study randomizes people in Uganda and South Africa with virologic failure on first-line therapy to standard of care virologic monitoring or immediate resistance testing. To strengthen external validity, study procedures are conducted within publicly supported laboratory and clinical facilities using local staff. To optimize cost estimates, we collect primary data on quality of life and medical resource utilization. To minimize losses from observation, we collect locally relevant contact information, including Whatsapp account details, for field-based tracking of missing participants. Finally, pregnant women are followed with an adapted protocol which includes an increased visit frequency to minimize risk to them and their fetuses. CONCLUSIONS: REVAMP is a pragammatic randomized clinical trial designed to test the effectiveness and cost-effectiveness of HIV resistance testing versus standard of care in sub-Saharan Africa. We anticipate the results will directly inform HIV policy in sub-Saharan Africa to optimize care for HIV-infected patients.

ABSTRACT

Tissue-engineered composite skin is a promising therapy for the treatment of chronic and acute wounds, including burns. Providing the wound bed with a dermal scaffold populated by autologous dermal and epidermal cellular components can further entice host cell infiltration and vascularization to achieve permanent wound closure in a single stage. However, the high porosity and the lack of a supportive basement membrane in most commercially available dermal scaffolds hinders organized keratinocyte proliferation and stratification in vitro and may delay re-epithelization in vivo. The objective of this study was to develop a method to enable the in vitro production of a human skin equivalent (HSE) that included a porous scaffold and dermal and epidermal cells expanded ex vivo, with the potential to be used for definitive treatment of skin defects in a single procedure. A collagen-glycosaminoglycan dermal scaffold (Integra(®)) was populated with adult fibroblasts. A near-normal skin architecture was achieved by the addition of coagulated human plasma to the fibroblast-populated scaffold before seeding cultured keratinocytes. This resulted in reducing scaffold pore size and improving contact surfaces. Skin architecture and basement membrane formation was further improved by the addition of aprotinin (a serine protease inhibitor) to the culture media to inhibit premature clot digestion. Histological assessment of the novel HSE revealed expression of keratin 14 and keratin 10 similar to native skin, with a multilayered neoepidermis morphologically comparable to human skin. Furthermore, deposition of collagen IV and laminin-511 were detected by immunofluorescence, indicating the formation of a continuous basement membrane at the dermal-epidermal junction. The proposed method was efficient in producing an in vitro near native HSE using the chosen off-the-shelf porous scaffold (Integra). The same principles and promising outcomes should be applicable to other biodegradable porous scaffolds, combined with autologous cells, for use in wound treatment.

ABSTRACT

OPINION STATEMENT: Family-based behavioral intervention has been demonstrated to be an effective and safe treatment for childhood obesity and should be considered a first-line treatment option. However, access to such intensive evidence-based treatment is limited and, currently, obesity care is dominated by high intensity behavioral treatment implemented in specialty clinics or less effective low intensity treatments implemented in primary care. However, capitalizing on the established and ongoing relationship between primary care providers and families, primary care providers have an invaluable role in early identification of overweight and obesity, and subsequent referral to an evidence-based treatment. Key aspects of effective treatment include: early intervention, moderate intensity to high intensity intervention of sufficient duration, multicomponent intervention targeting dietary modification, physical activity and behavioral strategies, family involvement and goals targeting family members, and follow-up contact during maintenance. The purpose of this review is to present the current empirically supported treatment options for pediatric obesity including primary care-based interventions and diagnostic tools, multicomponent behavioral intervention with a focus on family-based behavioral intervention, immersion treatment, and pharmacologic and surgical management.

ABSTRACT

PURPOSE: Screening for impaired glucose tolerance (IGT) is recommended for adolescents with polycystic ovary syndrome (PCOS) with oral glucose tolerance test (OGTT). Whether glycated hemoglobin (HbA1c) can be used for screening in this patient population is unknown. We sought to determine the utility of HbA1c and 2-hour OGTT for diagnosing dysglycemia in adolescents with PCOS. METHODS: This was a retrospective cohort study of 68 adolescents with PCOS seen in the Boston Children's Hospital Division of Adolescent Medicine between 2008 and 2011 and not known to have diabetes. Prevalence of dysglycemia (impaired fasting glucose, IGT, increased risk for diabetes, or diabetes mellitus as diagnosed by fasting plasma glucose, 2-hour OGTT, and/or HbA1c) and sensitivity and specificity of HbA1c for diagnosing dysglycemia compared with OGTT were assessed. RESULTS: Twenty-four participants had abnormal glucose testing, including one participant (1.5%) who met criteria for diabetes mellitus and 23 participants (34%) who met criteria for impaired fasting glucose/IGT/prediabetes. More patients were identified as having dysglycemia by HbA1c than OGTT. Compared with OGTT, HbA1c had a sensitivity of 60% and a specificity of 69% for diagnosing dysglycemia. CONCLUSIONS: In adolescents with PCOS, HbA1c had moderate sensitivity and specificity for detecting dysglycemia compared with OGTT. Clinicians should be aware that both tests have benefits and limitations, and the optimal test for follow-up requires further study.

ABSTRACT

INTRODUCTION: Cadaveric cutaneous allografts are used in burns surgery both as a temporary bio-dressing and occasionally as definitive management of partial thickness burns. Nonetheless, limitations in the understanding of the biology of these grafts have meant that their role in burns surgery continues to be controversial. METHODS: A review of all patients suffering 20% or greater total body surface area (TBSA) burns over an eight year period that received cadaveric allografts were identified. To investigate whether tissue viability plays a role in engraftment success, five samples of cryopreserved cadaveric cutaneous allograft processed at the Donor Tissue Bank of Victoria (DTBV) were submitted to our laboratory for viability analysis using two methods of Trypan Blue Exclusion and tetrazolium salt (MTT) assays. RESULTS: During the study period, 36 patients received cadaveric allograft at our institution. The average total burn surface area (TBSA) for this group of patients was 40% and all patients received cadaveric skin as a temporizing measure prior to definitive grafting. Cadaveric allograft was used in complicated cases such as wound contamination, where synthetic dressings had failed. Viability tests showed fewer than 30% viability in processed allografts when compared to fresh skin following the thawing process. However, the skin structure in the frozen allografts was histologically well preserved. CONCLUSION: Cryopreserved cutaneous cadaveric allograft has a positive and definite role as an adjunct to conventional dressing and grafting where available, particularly in patients with large TBSA burns. The low viability of cryopreserved specimens processed at DTBV suggests that cell viability in cadaveric allograft may not be essential for its clinical function as a wound dressing or even as permanent dermal substitute.

ABSTRACT

Studies examining trends over time in mainstream magazines observe decreases in women's figure size, and increases in figure exposure and amount of diet/exercise content. Little is known, however, regarding the content of African American magazines. Utilizing methods from classic studies, this investigation examined content in Ebony, a magazine with wide African American readership, from 1969 to 2008. We included the full content of N=462 issues, with a total of N=539 cover images of women, of which N=208 were full-body shots. Analyses indicated a curvilinear relationship between time and figure exposure, with a recent trend toward more full-body shots, similar to mainstream magazines. Contrary to previous studies, however, the majority of figures across time were average size, and a curvilinear relationship between time and diet/exercise content showed peak content in the early 1990s. Results are considered in context of research indicating African American women show less body dissatisfaction than other racial/ethnic groups.

ABSTRACT

Appropriate management of empyema thoracis is dependent upon a secure diagnosis of the etiology of empyema and the phase of development. Minimal access surgery using video-assisted thoracoscopy (VATS) is one of many useful techniques in treating empyema. Complex empyema requires adjunctive treatment in addition to VATS.

ABSTRACT

BACKGROUND: Managing immunosuppression is a significant aspect of posttransplantation patient care. Previously, our institution reported that prednisone could be withdrawn in cardiac allograft recipients without jeopardizing midterm survival. We returned to this group of patients to investigate the long-term effects of our steroid taper protocol. METHODS: We reviewed the records of 162 consecutive cardiac transplant recipients from our institution. Patients who underwent transplantation between 1988 and 1990 were treated with traditional triple-therapy immunosuppression (cyclosporine, azathioprine, and prednisone). Beginning June 1990, we instituted a protocol of early steroid taper with discontinuation by 6 months after transplant. The two groups were comparable with respect to age, sex, ethnicity, cause of heart failure, ischemic time, body mass index, and creatinine at the time of transplantation. RESULTS: Fifty-seven percent of the patients in the early steroid taper group were successfully withdrawn from steroids at 6 months after transplantation. This group had a decreased freedom from and increased frequency of acute rejection (p < 0.01 for each) when compared with the traditional therapy group. There was, however, no difference in freedom from posttransplant coronary artery disease (p = 0.53). The early steroid taper group enjoyed an increased freedom from malignancy (p = 0.01) and trended toward a decreased frequency of infection (p = 0.10) and improved survival (p = 0.06). CONCLUSIONS: Steroid withdrawal is possible in 57% of patients at 6 months after transplantation. The institution of an early steroid taper protocol improves the overall freedom from malignancies and may decrease the frequency of infection and prolong overall survival without increasing the risk of posttransplant coronary artery disease.

ABSTRACT

OBJECTIVE: Renal cell carcinomas often form venous thrombi that extend into the vena cava. Frequently, cardiovascular consultation is necessary for complete surgical excision. We sought to investigate the risk factors, surgical techniques, and outcomes of patients treated for renal cell carcinoma with venous extension. METHODS: We reviewed the records of 46 consecutive patients who underwent surgical management of renal cell carcinoma with venous extension between 1991 and 2005. Data on patient history, staging, surgical techniques, morbidity, and survival were analyzed. RESULTS: There were 29 men and 17 women with a mean age of 60.2 +/- 12.0 years. Twenty-five (54%) procedures were completed with cardiovascular assistance. Nephrectomy was performed in 44 (96%) cases. Three (7%) patients underwent right heart venovenous bypass, and 2 (5%) patients underwent cardiopulmonary bypass with circulatory arrest. Fourteen (32%) patients had perioperative complications, including 1 (2%) perioperative death. Patients who required cardiovascular procedures (inferior vena cava clamping, right heart venovenous bypass, and cardiopulmonary bypass with circulatory arrest) had higher risks of perioperative complications (P < .02). The 1-, 2-, and 5-year overall survival rates were 78%, 69%, and 56%. CONCLUSIONS: This large series demonstrates that aggressive treatment of renal cell carcinoma with venous thrombus provides favorable outcomes. Our 5-year survival is among the highest of recent reviews, and our perioperative morbidity and mortality rates are comparable with those of other series. Tumors that require cardiovascular procedures are associated with increased complications when compared with radical nephrectomy and thrombectomy alone. Nevertheless, this aggressive treatment approach offers encouraging patient survival.

ABSTRACT

BACKGROUND: Multiple studies have demonstrated an increased incidence of lung cancer in the heart transplant population. We reviewed our cardiac transplantation experience with respect to the development of bronchogenic carcinoma and explored the role of routine chest computed tomography (CT) in its surveillance. METHODS: We performed a review of our cardiac transplantation experience, highlighting the incidence of lung cancer, and we analyzed our recent experience with screening chest CT in lung cancer surveillance in this patient group. RESULTS: Eighteen patients developed 20 cases of bronchogenic carcinoma for an incidence of 6.83%. In 10 cases, the patients underwent surgical resection; however, in the remaining cases, the patients were either treated with chemotherapy and/or radiation or they died before initiation of therapy. The actuarial 1-, 2- and 5-year overall survival rates were 49%, 29% and 13%, respectively. The median survival of patients who underwent surgical resection was 28 months (3 to 85 months), whereas the median survival of patients who were either ineligible for surgery or died before initiation of treatment was only 1 month (1 to 13 months). All patients diagnosed with lung cancer by chest CT underwent surgical resection; however, only 37.5% of patients diagnosed with lung cancer by chest X-ray were found at an appropriate stage for resection (p = 0.025). CONCLUSIONS: Cardiac transplant recipients have a significant risk of developing bronchogenic carcinoma. Routine chest CT screening in high-risk patients may enable clinicians to identify disease earlier, which is essential for the option of surgical resection and, therefore, prolonged survival.
