A Literature Review of Digital Behavioral Parent Training Programs for Parents of Adolescents.

Parents of adolescents are faced with a variety of challenges related to their children's behavior and development. Behavioral parent training (BPT) programs may be effective strategies to mitigate adverse childhood experiences (ACEs) and other common behavioral problems in the adolescent period. Adolescence is the period following the onset of puberty and describes the transition from childhood to adulthood. Digital BPTs, including those delivered via the internet, downloaded digital content, text message, tablet, and video call, may present a unique opportunity to reach a broad audience of parents of adolescents by removing barriers to program accessibility (e.g., cost and transportation). We conducted a literature review to synthesize the existing evidence on digital BPTs for parents of adolescents. We described the digital BPTs, study designs, and evaluation and feasibility outcomes. A structured literature search identified studies meeting the following criteria for inclusion: (a) published between January 2000 and October 2022, (b) peer-reviewed, (c) available in English language, (d) study included a description of a digital BPT methodological approach, (e) study had to identify at least one parent or child behavioral outcome (e.g., parent-reported communication with their child) or feasibility outcome associated with the digital BPT, and (f) study included parents of adolescents aged 10-18 years. We extracted data on the characteristics of the study and demographic characteristics of participants, digital BPT, and evaluation and feasibility outcomes. Twenty-eight studies met inclusion criteria. Twenty-two unique digital BPTs were evaluated across the published studies. Thirteen digital BPTs (59.1%) were developed from or grounded by an identified theory. Six digital BPTs were freely accessible by the public, while the remaining 16 were available through study participation or purchase. One digital BPT was specifically tailored to parents of adolescents of a racial/ethnic minority group. Of the 16 studies that reported either parent or adolescent race/ethnicity, 10 consisted of more than 50% White parent or adolescent participants. Twenty-four (88.9%) studies provided evaluation data for the digital BPT. Fourteen studies (63.6%) employed a randomized control trial study design, and the remaining study designs included quasi-experimental (n = 2), mixed methods (n = 1), open trial (n = 3), case study (n = 1), pretest-posttest design (n = 1), and feasibility and acceptability trial (n = 2). All studies reported improvements in at least one parent-reported or adolescent-reported behavioral outcome or feasibility outcomes, with effect sizes (Cohen's d) ranging from small (e.g., 0.20-0.49) to very large (e.g., > 1.20). The findings of this review illustrate that technology may be a valuable way to deliver BPTs to parents of adolescents. However, few digital BPTs were developed for parents of adolescents from racial/ethnic minority groups, and many digital BPTs were not available without cost or participation in a research study. Considerations for future research are discussed.

A systematic review of the scientific evidence of venous supercharging in autologous breast reconstruction with abdominally based flaps.

BACKGROUND: Abdominally based free flaps are commonly used in breast reconstruction. A frequent complication is venous congestion, which might contribute to around 40% of flap failures. One way to deal with it is venous supercharging. The primary aim of this study was to investigate the scientific evidence for the effects of venous supercharging. METHODS: A systematic literature search was conducted in PubMed, CINAHL, Embase, and Cochrane library. The included articles were critically appraised, and certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. RESULTS: Thirty-six studies were included. Most studies had serious study limitations and problems with directness. Three studies report 'routine' use of venous supercharging and performed it prophylactically in patients who did not have clinical signs of venous congestion. Seventeen studies report on flap complications, of which one is a randomised controlled trial demonstrating statistically significant lower complication rates in the intervention group. The overall certainty of evidence for the effect of a venous supercharging on flap complications, length of hospital stay and operative time, in patients without clinical signs of venous congestion, is very low (GRADE ⊕ ⊕ ⊝ ⊝), and low on and surgical takebacks (GRADE ⊕ ⊕ ⊝ ⊝). Twenty-one studies presented data on strategies and overall certainty of evidence for using radiological findings, preoperative measurements, and clinical risk factors to make decisions on venous supercharging is very low (GRADE ⊕ ⊝ ⊝ ⊝). CONCLUSION: There is little scientific evidence for how to predict in which cases, without clinical signs of venous congestion, venous supercharging should be performed. The complication rate might be lower in patients in which a prophylactic venous anastomosis has been performed. TRIAL REGISTRATION: PROSPERO (CRD42022353591).

Transfusion Camp Rwanda: A prospective feasibility study evaluating the delivery of Transfusion Camp to a multidisciplinary group of postgraduate medical trainees in Rwanda.

BACKGROUND: Safe blood transfusion is an increasing priority in global health equity. The Global Health 2030 commission lists access to a safe blood supply as essential for all surgical and nonoperative patients. The objective of this study was to determine if Transfusion Camp, when modified through a collaborative partnership between experts in Canada and Rwanda, results in improved knowledge and confidence among trainees in a resource-limited setting in sub-Saharan Africa. METHODS: This prospective study took place at The University Teaching Hospital of Kigali in Rwanda. Participants were postgraduate medical trainees from departments where blood transfusion is frequent. Participants watched five prerecorded lectures and then attended a 5-hour team-based learning seminar to consolidate learning. Pre- and post-data were analyzed on transfusion knowledge and trainee confidence. A Rasch analysis investigated the performance of individual questions in assessing respondent knowledge. RESULTS: Of 31 trainees from surgery, anesthesia, internal medicine, and pediatrics invited to the course, 27 trainees attended the in-person team-based learning and 24 trainees completed the pre- and post-course analysis. Trainee knowledge assessment improved from (mean ± SD) 7.7/20 ± 1.95 to 10.4/20 ± 2.4 (p < .0001) and this knowledge was maintained by 12 trainees on a 3-month follow-up with a mean score of 9.3/20 ± 2.3. Trainees reported increased confidence in managing transfusion medicine-related patient issues. CONCLUSION: This pilot study demonstrated that Transfusion Camp education content modified to the local context can result in increased knowledge and confidence in managing transfusion-related issues. These results will inform future planning of Transfusion Camp in resource-limited settings.

Transfusion medicine education delivery in Rwanda: Adapting Transfusion Camp to a resource-limited setting.

BACKGROUND: Due to few teaching faculty, resource-limited settings may lack the education curricula providers need for safe practice. As safe surgery becomes an increasing priority worldwide, it is essential to improve access to critical education content including in transfusion medicine. Transfusion Camp is a longitudinal curriculum, shown to increase knowledge in postgraduate trainees. The objective was to develop a sustainable bilateral partnership between Rwanda and Canada, and to integrate Transfusion Camp into the existing curriculum of the School of Medicine and Pharmacy at University of Rwanda. METHODS: A Transfusion Camp pilot course was initiated through collaboration of experts in Rwanda and Canada. Planning occurred over 6 months via online and in-person meetings. Canadian teaching faculty adapted course content via iterative discussion with Rwandan faculty. Final content was delivered through online pre-recorded lectures by Canadian Faculty, and in-person small-group seminars by Rwandan Faculty. Project feasibility was assessed through structured evaluation and informal debriefing. RESULTS: Twenty-seven postgraduate trainees were present for the pilot course, of whom 21 (78%) submitted evaluation forms. While the structure and content of the adapted Transfusion Camp curriculum were well-received, the majority of respondents indicated a preference for in-person rather than pre-recorded lectures. Debriefing determined that future courses should focus on continuing education initiatives aimed at physicians entering or already in independent practice. CONCLUSION: A partnership between universities and blood operators in high-resource and resource-limited countries results in a transfusion medicine curriculum that is locally applicable, multidisciplinary, and supportive of learning benefitting the learners and educators alike.

Internal mammary perforator vessels as recipient for microvascular breast reconstruction: Technique and outcomes in 161 flaps.

BACKGROUND: The use of internal mammary perforator (IMP) vessels as recipients for free flap breast reconstruction was first described in 1999. Despite numerous advantages over the internal mammary (IM) and thoracodorsal recipient vessels, their widespread use remains mired in concern. This paper describes our method of IMP vessel preparation and outcomes with regard to safety and reliability. METHODS: To support the reliability of the IMP vessel preparation, a retrospective study on prospectively collected data of all free flap breast reconstruction patients between 1 July 2016 and 31 July 2019 was performed. Data were collected on patient demographics, type of reconstruction operative details and complications. RESULTS: Out of the 450 flaps performed, the IMP vessels were used in 36% of the cases. Of these cases, 18% had received neo-adjuvant chemotherapy and 15% had a history of radiotherapy to the chest wall. In total, 161 flaps were performed to reconstruct 138 breasts (115 single and 23 stacked flaps). Three patients required a return to theatre, with one needing recipient vessel revision from the IMP to the IM vessels due to calibre mismatch. No mastectomy skin flap necrosis, free flap loss or significant fat necrosis were encountered. CONCLUSION: This article describes an IM vessel preparation method that results in predictable outcomes in both single and stacked flap reconstructions with a low complication rate. Due to their reliability and versatility, we consider the IMP vessels a valuable attribute to the recipient vessel arsenal of any breast reconstruction microsurgeon.

A UK consensus statement on thromboprophylaxis for autologous breast reconstruction.

Microsurgical breast reconstruction accounts for 22% of breast reconstructions in the UK. Despite thromboprophylaxis, venous thromboembolism (VTE) occurs in up to 4% of cases. Using a Delphi process, this study established a UK consensus on VTE prophylaxis strategy, for patients undergoing autologous breast reconstruction using free-tissue transfer. It captured geographically divergent views, producing a guide that reflected the peer opinion and current evidence base. METHODS: Consensus was ascertained using a structured Delphi process. A specialist from each of the UK's 12 regions was invited to the expert panel. Commitment to three to four rounds of questions was sought at enrollment. Surveys were distributed electronically. An initial qualitative free-text survey was distributed to identify likely lines of consensus and dissensus. Each panelist was provided with full-text versions of key papers on the topic. Initial free-text responses were analyzed to develop a set of structured quantitative statements, which were refined via a second survey as a consensus was approached. RESULTS: The panel comprised 18 specialists: plastic surgeons and thrombosis experts from across the UK. Each specialist completed three rounds of surveys. Together, these plastic surgeons reported having performed more than 570 microsurgical breast reconstructions in the UK in 2019. A consensus was reached on 27 statements, detailing the assessment and delivery of VTE prophylaxis. CONCLUSION: To our knowledge, this is the first study to collate current practice, expert opinion from across the UK, and a literature review. The output was a practical guide for VTE prophylaxis for microsurgical breast reconstruction in any UK microsurgical breast reconstruction unit.

Association between three prehospital thoracic decompression techniques by physicians and complications: a retrospective, multicentre study in adults.

INTRODUCTION: We sought to compare the complication rates of prehospital needle decompression, finger thoracostomy and three tube thoracostomy systems (Argyle, Frontline kits and endotracheal tubes) and to determine if finger thoracostomy is associated with shorter prehospital scene times compared with tube thoracostomy. METHODS: In this retrospective cohort study we abstracted data on adult trauma patients transported by three helicopter emergency medical services to five Major Trauma Service hospitals who underwent a prehospital thoracic decompression procedure over a 75-month period. Comparisons of complication rates for needle, finger and tube thoracostomy and between tube techniques were conducted. Multivariate models were constructed to determine the relative risk of complications and length of scene time by decompression technique. RESULTS: Two hundred and fifty-five patients underwent 383 decompression procedures. Fifty eight patients had one complication, and two patients had two complications. There was a weak association between decompression technique (finger vs tube) and adjusted risk of overall complication (RR 0.58, 95% CI: 0.33-1.03, P = 0.061). Recurrent tension physiology was more frequent in finger compared with tube thoracostomy (13.9 vs 3.2%, P < 0.001). Adjusted prolonged (80th percentile) scene time was not significantly shorter in patients undergoing finger vs tube thoracostomy (56 vs 63 min, P = 0.197), nor was the infection rate lower (2.7 vs 2.1%, P = 0.85). CONCLUSIONS: There was no clear evidence for benefit associated with finger thoracostomy in reducing overall complication rates, infection rates or scene times, but the rate of recurrent tension physiology was significantly higher. Therefore, tube placement is recommended as soon as practicable after thoracic decompression.

Stacked TUG and DIEP flaps to reconstruct a single breast: Expanding the scope of autologous breast reconstruction.

When the entire abdominal tissue is inadequate to match the contralateral breast volume and shape or in bilateral cases, the deep inferior epigastric perforator (DIEP) flap alone might not be adequate, even if bipedicled. In such cases, using combinations of donor sites is useful and more effective. We present our series of breast reconstruction using stacked DIEP and transverse upper gracilis (TUG) flaps to achieve better breast volume and shape. Between 2015 and 2021, 7 patients underwent reconstruction with stacked flaps. Three surgical teams performed the surgery simultaneously. Flaps were stacked and shaped on a table; the DIEP was de-epithelised completely and placed upside down with the pedicle anteriorly. A cranial extension of the DIEP pedicle was anastomosed in series to the TUG vessels. The TUG was coned and placed above the DIEP, the skin paddle was used both to create a new nipple-areola complex and for monitoring. The stacked flaps were anastomosed to the recipient vessels and buried under the mastectomy flaps. No flap losses were encountered. The aesthetic outcome was good or excellent and patients considered the surgery as an improvement for their self-appearance. In patients with loose skin and minimal fat, or in bilateral reconstructions, the presented procedure can be considered as a reliable approach to obtain a better breast shape and simultaneously improve body contouring in the donor sites.

Unilateral breast reconstruction using double transverse upper gracilis (TUG) flaps.

INTRODUCTION: When the deep inferior epigastric perforator (DIEP) flap is unavailable, autologous reconstruction of a moderate-to-large breast presents a surgical challenge. We retrospectively review our experience of unilateral breast reconstruction using double transverse upper gracilis (TUG) flaps and highlight specific technical considerations. METHODS: Thirty-four patients underwent double TUG flaps for unilateral breast reconstruction between 2012 and 2020. The average patient age was 50 years and the average body mass index (BMI) was 23.1 kg/m2. In all cases, the indication for surgery was breast cancer: 31 patients had immediate reconstruction, 11 had simultaneous axillary surgery and eight had primary contralateral symmetrising surgery. RESULTS: Of the 68 TUG flaps, 67 (98.5%) were successful. The mean operative time was 5 h 50 min (195-460 min) and the mean combined flap weight was 551 g (279-916 g). Eight patients returned to the operating theatre in the early post-operative period and five patients underwent secondary lipofilling to address contour deformities. Most commonly (n = 22), the flaps were oriented horizontally/obliquely, with one flap anastomosed medially to the internal mammary axis and the other anastomosed lateral to the subscapular system. The internal mammary artery perforators and serratus anterior artery provided the best vessel calibre match with the TUG vessels. CONCLUSIONS: Double TUG reconstruction is a safe and reliable option for unilateral breast reconstruction and is an important option when the DIEP flap is unavailable.

An Atypical Presentation of Hemophagocytic Lymphohistiocytosis (HLH) Secondary to Occult Hodgkin Lymphoma.

Hemophagocytic lymphohistiocytosis (HLH) is a rare and life-threatening syndrome of immune system dysregulation characterized by the phagocytosis of various cells by histiocytes in the bone marrow. HLH can present in one of the two ways: primary HLH, which is caused by mutations in genes essential to T and NK-cell function, and secondary HLH, typically caused by Epstein-Barr virus (EBV) infection or malignancy. Because of the rapid progression and high mortality of this disease, prompt diagnosis is essential to good outcomes. Here, we report the 2-month clinical course of a patient who presented with altered mental status and recurrent fever of unknown origin. Initially, he did not meet diagnostic criteria for HLH and had a negative bone marrow biopsy; however, he eventually progressed to full-blown HLH secondary to occult Hodgkin lymphoma. This case is unusual for the slow and smoldering course of the patient's disease and highlights the importance of aggressively searching for potential malignancies to ensure the initiation of definitive therapy as soon as possible.

An NP-led pilot telehealth programme to facilitate guideline-directed medical therapy for heart failure with reduced ejection fraction during the COVID-19 pandemic.

AIMS: Heart failure with reduced ejection fraction (HFrEF) is associated with poor outcomes. While several medications are beneficial, achieving optimal guideline-directed medical therapy (GDMT) is challenging. COVID-19 created a need to explore new ways to deliver care. METHODS: Fifty consecutive patients were taught to identify fluid congestion and monitor their vital signs using BP monitors and electronic scales with NP-led telephone support. Quantitative data were collected and a patient experience interview was performed. RESULTS: The majority (76%) of the cohort (male, 76%; Maori/Pacific, 58%) had a new diagnosis of HFrEF, with 90% having severe left ventricular (LV) dysfunction. There were 216 contacts (129 (60%) by telephone), which eliminated travelling, (time saved, 2.12 hours per patient), petrol costs ($58.17 per patient), traffic pollution (607 Kg of CO2) and time off work. Most (75%) received contact within two weeks and 75% were optimally titrated within two months. Improvements in systolic BP (SBP) (124mmHg to 116mmHg), pulse (78 bpm to 70 bpm) and N-terminal pro-brain natriuretic peptide (NT-proBNP) (292 to 65) were identified. Of the 43 patients who had a follow-up transthoracic echocardiogram (TTE), 33 (77%) showed important improvement in left ventricular ejection fraction (LVEF). CONCLUSIONS: Patients found the process acceptable and experienced rapid titration with less need for clinic review with titration rates comparable with most real-world reports.

Preoperative volume estimation in transverse upper gracilis flap surgery: A pilot study.

BACKGROUND: The transverse upper gracilis (TUG) flap provides a good alternative to the gold standard DIEP in breast reconstruction. However, flap volume estimates are subjective, making preoperative planning potentially challenging. STUDY AIM: To derive a reliable, accurate, and reproducible mathematical algorithm for the preoperative calculation of TUG flap volumes. MATERIALS AND METHODS: Nineteen consecutive patients with 30 TUG flaps were prospectively included. On the assumption that the TUG flap resembles two isosceles prisms, the formula of the volume of a prism was used to calculate their preoperative flap weights. These were then intraoperatively compared to the actual flap weights. A regression equation was calculated from the correlation analysis of 10 random flaps. This was then applied to the remaining 20 flaps to assess for improved reliability and weight prediction accuracy. RESULTS: The prism volume equation used to clinically calculate flap volumes was: Geometric flap weight = (h1bT)/2+ (h2bT)/2, (h = height, b = base, T = flap thickness); all in centimetres. Geometric and actual flap weights were found to be significantly correlated (r2 = 0.977) generating the following regression formula: predicted TUG weight = 0.924 × geometric weight + 26.601. When this was applied to the remaining 20 flaps, no significant difference was found (p = 0.625) between predicted and actual flap weights, demonstrating an increased accuracy of predicting flap volume. CONCLUSION: The proposed formula provides the clinician with a more accurate and reliable estimation of available TUG flap volume and may potentially aid with preoperative planning and patient consultations.

This case report describes the use of a mechanical ventilator and visible advanced monitoring throughout the entirety of the patient journey from the prehospital scene to the hospital, including the period during hoist extraction as human external cargo.

Characteristics and outcomes of primary interposition vascular grafts in free flap breast reconstruction.

INTRODUCTION: There is paucity of data on primary interposition vascular grafts (IVG) use in microsurgery. Our study examines the characteristics, indications and outcomes of IVG in free flap breast reconstruction. METHODS: All cases of breast reconstruction with free flaps between January 2013 and June 2018 were examined and cases with primary IVG were included. Data were collected on patient, flap and graft characteristics, indications and outcomes. RESULTS: A total of 76 IVG, specifically 65 vein grafts and 11 arterial grafts, were used for 49 (of 1547) flaps in 48 (of 1346) cases. Of these, 52 grafts were primarily used to lengthen the pedicle and aid flap inset and 24 grafts to augment venous flow; 49 grafts were harvested from the flap harvest site, 7 from the anastomosis recipient site and 20 from a separate site. Of the total, 16.7% (8/49 flaps) required salvage procedures - seven cases for venous congestion and one for ischaemic compromise - in comparison to 4.3% in cases without IVG (65/1498) (p<0.0001). Out of 49 IVG flaps, three (6.1%) failed in comparison to 1.7% (26/1498), where IVG flaps were not used (p<0.05). Two were transverse upper gracilis flaps with vessel calibre mismatch, and one lumbar artery perforator (LAP) flap with past infected implant and failed deep inferior epigastric artery (DIEP). CONCLUSION: We present the largest number of primary vascular grafts for free flap breast reconstruction in the literature. Primary IVG were used for at-risk flaps and had a success rate of 93.9%. This shows that IVG are a viable option to prevent venous congestion and lengthen the pedicle to aid inset and shaping; they are associated with higher complication rates bearing in mind the high-risk profile of the flaps these are used for.

Exemplification and the use-values of cases and case studies.

This paper provides an account of the 'use-value' of case-based research by showing how social scientists exploit cases, and case studies, in a variety of practices of inference and extension. The critical basis for making such extensions relies on the power of a case, or the account given of a case (the case-study account), to exemplify certain features of the social world in ways which prove valuable for further analysis: either of the same case, or in many domains beyond the original case study. Framing use-values in terms of exemplification compares favourably with understanding reasoning beyond the case either as a form of analogical reasoning or in taking cases as experimentable objects.
