RESUMO

PURPOSE: Standard tools for public health decision making such as data dashboards, trial repositories, and intervention briefs may be necessary but insufficient for guiding community leaders in optimizing local public health strategy. Predictive modeling decision support tools may be the missing link that allows community level decision makers to confidently direct funding and other resources to interventions and implementation strategies that will improve upon the status quo. METHODS: We describe a community-based model-driven decision support (MDDS) approach that requires community engagement, local data, and predictive modeling tools (agent-based modeling in our case studies) to improve decision-making on implementing strategies to address complex public health problems such as overdose deaths. We refer to our approach as a meta-implementation strategy as it provides guidance to a community on what intervention combinations and their required implementation strategies are needed to achieve desired outcomes. We use standard implementation measures including the Stages of Implementation Completion to assess adoption of this meta-implementation approach. RESULTS: Using two case studies, we illustrate how MDDS can be used to support decision making related to HIV prevention and reductions in overdose deaths at the city and county level. Even when community acceptance seems high, data acquisition and diffuse responsibility for implementing specific strategies recommended by modeling are barriers to adoption. CONCLUSIONS: MDDS has the capacity to improve community decision makers use of scientific knowledge by providing projections of the impact of intervention strategies under various scenarios. Further research is necessary to assess its effectiveness and the best strategies to implement it.

RESUMO

Peripheral nerve injuries (PNIs) occur frequently and can lead to devastating and permanent sensory and motor function disabilities. Systemic tacrolimus (FK506) administration has been shown to hasten recovery and improve functional outcomes after PNI repair. Unfortunately, high systemic levels of FK506 can result in adverse side effects. The localized administration of FK506 could provide the neuroregenerative benefits of FK506 while avoiding systemic, off-target side effects. This study investigates the utility of a novel FK506-impregnated polyester urethane urea (PEUU) nerve wrap to treat PNI in a previously validated rat infraorbital nerve (ION) transection and repair model. ION function was assessed by microelectrode recordings of trigeminal ganglion cells responding to controlled vibrissae deflections in ION-transected and -repaired animals, with and without the nerve wrap. Peristimulus time histograms (PSTHs) having 1 ms bins were constructed from spike times of individual single units. Responses to stimulus onsets (ON responses) were calculated during a 20 ms period beginning 1 ms after deflection onset; this epoch captures the initial, transient phase of the whisker-evoked response. Compared to no-wrap controls, rats with PEUU-FK506 wraps functionally recovered earlier, displaying larger response magnitudes. With nerve wrap treatment, FK506 blood levels up to six weeks were measured nearly at the limit of quantification (LOQ ≥ 2.0 ng/mL); whereas the drug concentrations within the ION and muscle were much higher, demonstrating the local delivery of FK506 to treat PNI. An immunohistological assessment of ION showed increased myelin expression for animals assigned to neurorrhaphy with PEUU-FK506 treatment compared to untreated or systemic-FK506-treated animals, suggesting that improved PNI outcomes using PEUU-FK506 is mediated by the modulation of Schwann cell activity.

RESUMO

Introduction: Poor adherence to antipsychotic medication is common in the treatment of schizophrenia and other psychotic disorders. Paliperidone palmitate 3-monthly (PP3M) is the first long-acting injectable (LAI) antipsychotic to allow for only four medication administrations per year, and although there is sufficient information available about the clinical effects, there is relatively limited insight into the subjective experience of people with lived experience. Methods: This descriptive, cross-sectional survey explored patient's satisfaction and perspectives on the advantages and disadvantages of switching from monthly to 3-monthly paliperidone while also reporting on perceived levels of safety with regard to the reducing dose regimen during the Covid-19 pandemic. Information on discontinuation and hospitalisation rates at one year was also collected from the electronic records. Results: Of the 46 patients included in the study, the vast majority reported feeling satisfied (89.2%) and safer (93.5%) after switching to the three-monthly formulation. Participants highlighted several advantages of changing to PP3M, most notably convenience (93.5%), improved quality of life (58.7%), decreased stigma (39.1%) and better adherence (28.3%). Furthermore, 93.5% of respondents experienced no disadvantages, while 6.5% described worsening side effects or symptoms. In fact, only one patient discontinued PP3M at one year with the overall number of hospitalisations also reducing in the same period compared to the year before switching. Discussion: Our findings add to the small, but growing, body of evidence supporting patient satisfaction and acceptance with the use of PP3M and may reinforce the use of less frequent LAIs in clinical practice to enhance individual experience and treatment persistence and decrease levels of stigmatisation.

RESUMO

MOTIVATION: In recent years, a growing number of spatial epigenome datasets have been generated, presenting rich opportunities for studying the regulation mechanisms in solid tissue sections. However, visual exploration of these datasets requires extensive computational processing of raw data, presenting a challenge for researchers without advanced computational skills to fully explore and analyze such datasets. RESULTS: Here, we introduce AtlasXplore, a web-based platform that enables scientists to interactively navigate a growing collection of spatial epigenome data using an expanding set of tools.

RESUMO

BACKGROUND: Long-acting injectable antipsychotics (LAIs) have been shown to improve adherence and prevent relapse in the treatment of schizophrenia and psychotic disorders, though longitudinal data on treatment outcomes are limited. OBJECTIVES: To establish the long-term acceptability and effectiveness of paliperidone palmitate once monthly (PP1M). METHODS: This independent 10-year mirror image study was carried out in a large urban mental health provider. The study evaluated the retention and hospitalization rates 5 years following initiation of PP1M in a naturalistic patient cohort of all adult patients who were newly initiated on PP1M between 2011 and 2015. Electronic records were used to compare the frequency and length of hospital admissions in the 5 years before and after introduction of PP1M. Switching and discontinuation rates and reasons were also recorded with a separate analysis of patients who continued and discontinued PP1M during the study period. RESULTS: A total of 167 patients were included in the study (70% with schizophrenia, 30% with other diagnoses). Discontinuation rates were 24%, 15%, 17%, 5% and 8% in years 1-5, respectively; poor tolerability was the most common cause for stopping PP1M. Demographic and clinical factors such as age, sex, diagnosis and care setting did not discriminate between continuers and discontinuers. The group that completed 5 years on PP1M (46%) showed an overall reduction of 72% in the mean number and 68% in the mean length of admissions compared to the 5-year period before initiation, with more than half of the patients requiring no admission at all during this period of time (median = 0). On the contrary, discontinuers demonstrated worse outcomes in overall bed occupancy than continuers. Findings were overall similar across the total cohort and schizophrenia-only group. CONCLUSIONS: Our study has one of the longest durations of follow up of a naturalistic cohort treated with LAIs confirming sustained improvements for patients who continued treatment for up to 5 years with implicit implications for cost effectiveness. Study findings may facilitate shared decision making in this area, overcoming some of the common barriers for use.

RESUMO

BACKGROUND AND OBJECTIVE: To provide an overview of progressive retinoschisis-related retinal detachment (RSRD) management at a tertiary referral center. MATERIALS AND METHODS: Single-institution retrospective case series from January 1, 2003, to May 1, 2020. RESULTS: Progressive RSRD occurred in 0.9% of patients with retinoschisis. Mean (range) age at time of surgery was 58.7 years (40.0 to 74.0). Ten eyes were initially treated with scleral buckle, three eyes with vitrectomy, and three eyes with combined scleral buckle and vitrectomy. Overall reattachment rate was 100.0%; single-surgery success was 56.2%. Proliferative vitreoretinopathy developed in 10.0% of scleral buckles, 33.3% of vitrectomies, and 33.3% of combined surgeries. CONCLUSIONS: Progressive RSRD is rare and poses surgical management challenges. Final retinal attachment can be achieved successfully but often requires secondary and staged surgeries. Localization of outer retinal breaks may help guide surgical management. Further research-such as a large-scale, prospective, multicenter, randomized trial-would be needed to determine the optimal surgical technique.

RESUMO

PURPOSE: Retinal detachment (RD) is associated with poor visual outcomes in patients with acute retinal necrosis (ARN). This research was undertaken to assess the risk factors for RD in ARN. DESIGN: Retrospective cohort study. SUBJECTS: Patients diagnosed with ARN at a tertiary referral center from 2010 to 2020. METHODS: A chart review was performed for all clinical and surgical encounters. Univariate and multivariate logistic analyses of demographic and clinical variables associated with RD were performed. Survival analyses with Kaplan-Meier estimates were performed to compare the time to RD in herpes simplex virus (HSV)- and varicella zoster virus (VZV)-associated ARN. MAIN OUTCOME MEASURES: Demographic information, clinical information (including visual acuity [VA]), intraocular pressure (IOP), intraocular inflammation level, the extent of retinitis, incidence and timing of retinal detachment, date of diagnosis, and treatments performed (including intravitreal injections of antiviral medications). RESULTS: Fifty-four eyes of 47 patients who were diagnosed with ARN were included, with equal proportions of eyes (n = 27; 50%) with VZV-ARN and HSV-ARN. Patients with VZV-ARN were, on average, older, more likely to be men, and more likely to be immunosuppressed compared with patients with HSV-ARN. The clinical characteristics, including the initial VA, initial IOP, anterior segment inflammation, clock hours, and posterior extent of retinitis, were similar between eyes with VZV- and HSV-ARN. In the univariate analysis of clinical and demographic variables associated with the development of RD, initial VA (P = 0.0083) and greater clock hours of retinitis (P = 0.009) were significantly associated with RD. These 2 variables remained significant in the multivariate logistic regression; worse VA at presentation had an odds ratio of 2.34 (95% confidence interval [CI], 1.01-5.44; P = 0.042), and greater clock hours of retinitis had an odds ratio of 1.23 (95% CI, 1.02-1.47; P = 0.025). A Kaplan-Meier survival analysis demonstrated no statistical difference in RD-free survival between HSV- and VZV-ARN. CONCLUSIONS: Patients with VZV-ARN were more likely to be older, male, and immunosuppressed compared with those with HSV-ARN, although no clear difference was observed in RD by viral etiology. Poor initial VA and clock hours of retinitis were significantly associated with RD development and may be relevant for patient counseling and prognosis.

RESUMO

PURPOSE: To describe a potential case of pentosan polysulfate maculopathy that seemed to manifest nearly 3 years after drug cessation. METHODS: Complete ophthalmic examination, including multimodal fundus imaging, electroretinography, automated perimetry, and molecular testing, was performed. RESULTS: A 44-year-old woman with a 435 g cumulative exposure to pentosan polysulfate sodium presented 38 months after drug cessation with 6 months of worsening metamorphopsia and prolonged dark adaptation. Fundus examination and multimodal fundus imaging demonstrated characteristic features of pentosan polysulfate maculopathy, and molecular testing was unremarkable. By contrast, color fundus photographs of the same patient acquired at an outside facility 25 months before did not display features consistent with pentosan polysulfate sodium maculopathy. CONCLUSION: This case suggests that new-onset clinically detectable pentosan polysulfate maculopathy may develop years after drug cessation. If corroborated, this finding has important ramifications for pentosan polysulfate sodium dosing and surveillance guidelines.

RESUMO

AIMS: The Covid-19 pandemic has had a substantial impact on the mental health of the general public and high-risk groups worldwide. Due to its proximity and close links to China, Southeast Asia was one of the first regions to be affected by the outbreak. The aim of this systematic review was to evaluate the prevalence of anxiety, depression and insomnia in the general adult population and healthcare workers (HCWs) in Southeast Asia during the course of the first year of the pandemic. METHODS: Several literature databases were systemically searched for articles published up to February 2021 and two reviewers independently evaluated all relevant studies using pre-determined criteria. The prevalence rates of mental health symptoms were calculated using a random-effect meta-analysis model. RESULTS: In total, 32 samples from 25 studies with 20 352 participants were included. Anxiety was assessed in all 25 studies and depression in 15 studies with pooled prevalence rates of 22% and 16%, respectively. Only two studies assessed insomnia, which was estimated at 19%. The prevalence of anxiety and depression was similar among frontline HCWs (18%), general HCWs (17%), and students (20%) while being noticeably higher in the general population (27%). CONCLUSIONS: This is the first systematic review to investigate the mental health impact of the Covid-19 pandemic in Southeast Asia. A considerable proportion of the general population and HCWs reported mild to moderate symptoms of anxiety and depression; the pooled prevalence rater, however, remain significantly lower than those reported in other areas such as China and Europe.

RESUMO

BACKGROUND: The pragmatic management of psychotic disorders is more complex than that delivered in a controlled trial environment. Therefore, this study aims to evaluate the real-world effectiveness of aripiprazole long-acting injectable (ALAI) and compare it with another commonly used long-acting anti-psychotic, once-monthly paliperidone palmitate (PP1M). METHODS: This naturalistic, independent 4-year mirror image study compared the mean number and length of hospital admissions 2 years before and 2 years after treatment initiation with ALAI. Retention rates, discontinuation reasons and level of adherence were also recorded. Furthermore, indirect comparisons were made between treatment outcomes on ALAI and PP1M. RESULTS: A total of 109 eligible patients with a severe mental illness (65% with schizophrenia and 35% with other diagnosis) commenced on ALAI and 173 patients (69% with schizophrenia and 31% with other diagnoses) initiated on PP1M were included. Of these, 37% on ALAI and 34% on PP1M stopped treatment at 2 years; retention rates were most favourable for the schizophrenia group on PP1M. Patients were more likely to discontinue due to lack of effectiveness on ALAI and due to tolerability issues on PP1M. Those who continued for 2 years on ALAI (n = 69), demonstrated an overall decrease of 84% in the mean number and 88% in the mean length of hospital admissions compared with the 2 years before initiation. Although patients on ALAI appeared to have a significantly higher bed occupancy the 2-year period before initiation than patients on PP1M, the reductions in hospitalizations were comparable across both cohorts after 2 years of treatment. CONCLUSIONS: The introduction of ALAI had a substantial impact on long-term clinical outcomes in this naturalistic cohort; more than half of patients continued treatment and had no admission during 2 years of follow up. There were no significant differences in hospitalisation rates between patients on ALAI and PP1M at 2 years.

RESUMO

PURPOSE: To assess the prevalence of retinopathy and its association with systemic morbidity and laboratory indices of coagulation and inflammatory dysfunction in severe COVID-19. DESIGN: Retrospective, observational cohort study. METHODS: Adult patients hospitalized with severe COVID-19 who underwent ophthalmic examination from April to July 2020 were reviewed. Retinopathy was defined as one of the following: 1) Retinal hemorrhage; 2) Cotton wool spots; 3) Retinal vascular occlusion. We analyzed medical comorbidities, sequential organ failure assessment (SOFA) scores, clinical outcomes, and laboratory values for their association with retinopathy. RESULTS: Thirty-seven patients with severe COVID-19 were reviewed, the majority of whom were female (n = 23, 62%), Black (n = 26, 69%), and admitted to the intensive care unit (n = 35, 95%). Fourteen patients had retinopathy (38%) with retinal hemorrhage in 7 (19%), cotton wool spots in 8 (22%), and a branch retinal artery occlusion in 1 (3%) patient. Patients with retinopathy had higher SOFA scores than those without retinopathy (8.0 vs. 5.3, p = .03), higher rates of respiratory failure requiring invasive mechanical ventilation and shock requiring vasopressors (p < .01). Peak D-dimer levels were 28,971 ng/mL in patients with retinopathy compared to 12,575 ng/mL in those without retinopathy (p = .03). Peak CRP was higher in patients with cotton wool spots versus those without cotton wool spots (354 mg/dL vs. 268 mg/dL, p = .03). Multivariate logistic regression modeling showed an increased risk of retinopathy with higher peak D-dimers (aOR 1.32, 95% CI 1.01-1.73, p = .04) and male sex (aOR 9.6, 95% CI 1.2-75.5, p = .04). CONCLUSION: Retinopathy in severe COVID-19 was associated with greater systemic disease morbidity involving multiple organs. Given its association with coagulopathy and inflammation, retinopathy may offer insight into disease pathogenesis in patients with severe COVID-19.

RESUMO

PURPOSE OF REVIEW: The purpose of this review is to summarize complications of treatment for retinopathy of prematurity (ROP) and to compare complications of laser and intravitreal antivascular endothelial growth factor (VEGF) injections. RECENT FINDINGS: Poor structural outcomes and myopia are more common with laser for severe ROP than with anti-VEGF. Clinical trial data show unfavourable outcomes in 9.1-9.5% of laser treated, and 1.4-3.6% of anti-VEGF treated eyes. Additional randomized trial data show risk for very high myopia (≥-8.00D) to be 3.8 and 51.4% for zone I eyes treated with bevacizumab and laser, respectively. However, anti-VEGF may be complicated by late recurrence and is more likely to require retreatment than laser. Laser often necessitates general anaesthesia with its attendant risks, including worse short-term respiratory outcomes. Neurodevelopmental complications have been reported with anti-VEGF, but existing studies are subject to bias. SUMMARY: Treatment complications are substantially different for the two modalities in common use today. In more severe cases, risk of poor structural outcome and myopia favour treatment with anti-VEGF. In less severe ROP, risk of recurrence and the need for additional treatments may favour laser. Additional data are needed to establish comparative risks of neurodevelopmental complications.

RESUMO

The burden of the COVID-19 pandemic on health systems and the physical and mental health of healthcare workers (HCWs) has been substantial. This cross-sectional study aims to assess the effects of COVID-19 on the psychological wellbeing of mental health workers who provide care to a vulnerable patient population that have been particularly affected during this crisis. A total of 387 HCWs from across a large urban mental health service completed a self-administered questionnaire consisting of socio-demographic, lifestyle and work-based information and validated psychometric scales. Depression and anxiety were measured using the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder Scale (GAD-7), respectively; sleep problems with the Athens Insomnia Scale (AIS); burnout with the Maslach Burnout Inventory (MBI); and resilience with the Resilience Scale-14 (RS-14). Multivariable logistic regression analysis was performed to determine potential mediating factors. Prevalence of burnout was notable, with 52% recording moderate/severe in Emotional Exhaustion, 19.5% moderate/severe in Depersonalisation, and 55.5% low/moderate Personal Accomplishment. Over half of all respondents (52%) experienced sleep problems; the presence of depressive symptoms was a significant predictor of insomnia. An increase in potentially harmful lifestyle changes, such as smoking, alcohol consumption and overeating was also observed. However, high Resilience was reported by 70% of the samples and the importance of this is highlighted. Female gender was associated with increased levels of depression and emotional exhaustion while those with a history of mental health conditions were most at risk of affective symptoms, insomnia, and burnout. Overall, our study revealed considerable levels of psychological distress and maladaptive coping strategies but also resilience and satisfaction with organizational support provided. Findings can inform tailored interventions in order to mitigate vulnerability and prevent long-term psychological sequelae.

RESUMO

Personalised care involves shared decision making (SDM) across all levels including choice in medication. However, there are a number of barriers which prevent its effective implementation in routine mental health settings. Therefore, we undertook a study to benchmark current practice across clinical services of a large urban mental health provider. The study formed part of the trust-wide 'Supported Decision Making in Medication' Co-Production Project and aims to inform future recommendations in delivering against contemporary best practice, guidance and policy. A survey exploring the views and experiences of service users and prescribers on shared and supported decision-making in medication was carried out in West London NHS Trust. Questionnaires were fully co-designed and co-delivered by a group of health professionals and individuals with lived experience. There were 100 responses from service users and 35 from prescribers. There was some good practice where both parties reported good quality conversations concerning dialogic styles, collaborative process, information provided and range of choice offered. However, prescriber's perception of their practice was not always mirrored by service user feedback whose experiences often depended upon the prescriber, the time available or the part of the service. Generally, service user experience fell short of the good practice cited by clinicians though there was noticeable variability. Commitment from organizations and increasing understanding from practitioners are vital in transforming SDM from rhetoric into reality. From our findings a further challenge is to ensure that prescribers and service users have the time, information and tools to implement it consistently.

RESUMO

The helical structures of DNA and RNA were originally revealed by experimental data. Likewise, the development of programs for modeling these natural polymers was guided by known structures. These nucleic acid polymers represent only two members of a potentially vast class of polymers with similar structural features, but that differ from DNA and RNA in the backbone or nucleobases. Xeno nucleic acids (XNAs) incorporate alternative backbones that affect the conformational, chemical, and thermodynamic properties of XNAs. Given the vast chemical space of possible XNAs, computational modeling of alternative nucleic acids can accelerate the search for plausible nucleic acid analogs and guide their rational design. Additionally, a tool for the modeling of nucleic acids could help reveal what nucleic acid polymers may have existed before RNA in the early evolution of life. To aid the development of novel XNA polymers and the search for possible pre-RNA candidates, this article presents the proto-Nucleic Acid Builder (https://github.com/GT-NucleicAcids/pnab), an open-source program for modeling nucleic acid analogs with alternative backbones and nucleobases. The torsion-driven conformation search procedure implemented here predicts structures with good accuracy compared to experimental structures, and correctly demonstrates the correlation between the helical structure and the backbone conformation in DNA and RNA.

RESUMO

Previous metabolomics studies from our lab found altered plasma levels of bile acids in patients with age-related macular degeneration (AMD) compared to controls. In this study, we investigated the ability of the bile acid taurocholic acid (TCA) to inhibit features of AMD modeled in vitro. Paraquat was used to induce oxidative stress in HRPEpiC primary retinal pigment epithelial (RPE) cells. Cells were treated with 300 µM paraquat alone or with TCA (10, 50, 100, 200, or 500 µM). RPE tight junction integrity was assessed via ZO-1 immunofluorescence and transepithelial electrical resistance (TEER) measurements. RF/6A macaque choroidal endothelial cells were treated with 100 ng/mL vascular endothelial growth factor (VEGF) to induce angiogenesis. The effect of TCA on VEGF-induced angiogenesis was evaluated with cell proliferation, cell migration, and tube formation assays. Addition of TCA at 100 (P = 8.6 × 10-4), 200 (P = 0.0035), and 500 (P = 2.1 × 10-4) µM resulted in significant preservation of TEER in paraquat treated cells. In RF/6A cells, TCA did not significantly affect VEGF-induced cell proliferation. VEGF-induced migration of RF/6A cells was significantly inhibited at TCA concentrations of 100 (P = 0.010), 200 (P = 0.023) and 500 (P = 0.0049) µM. VEGF-induced tube formation was significantly inhibited when treated with 200 (P = 0.014) and 500 (P = 7.1 × 10-4) µM TCA. In vitro, TCA promoted RPE cell integrity and diminished VEGF-induced choroidal endothelial cell migration and tube formation. This suggests that TCA may have protective effects against both degenerative and neovascular AMD.

OBJECTIVE: To describe a reliable method utilizing large, rotation flaps to reconstruct a number 10 Tessier cleft. DESIGN: This is a descriptive clinical case report. SETTING: Pediatric teaching hospital affiliated with a university. PATIENTS, PARTICIPANTS: One participant in this clinical case report. INTERVENTIONS: Full-thickness excision of the clefted eyelid, brow, and forehead tissue was performed bilaterally to develop medial and lateral eyebrow and forehead flaps. Right: the forehead/brow flap was rotated caudally to reapproximate the eyebrow and an eyelid rotation flap was also used to reapproximate the lid margin. Left: forehead/brow rotation flap allowed realignment of the eyebrow and a series of Z-plasties were used in the eyelid to reapproximate the lid margin and to lengthen the eyelid. MAIN OUTCOME MEASURE(S): Develop and construct a reliable reconstruction with full-eyelid closure and minimal donor site morbidity. RESULTS: Complete eyelid closure bilaterally was achieved intraoperatively, and was maintained at 6-month follow-up with no evidence of ocular pathology. CONCLUSIONS: Large, bilateral upper eyelid colobomas require repair to prevent blindness. Although free tarsomarginal grafts and lid-sharing procedures have been described, we demonstrate that large rotation flaps designed along the cleft margin can provide a reliable reconstruction and minimize donor-site morbidity.

RESUMO

BACKGROUND: Body contouring complications after massive weight loss (MWL) vary significantly in frequency and type. Currently, no standardized recommendations exist regarding which complications are most important to report. OBJECTIVES: We aim to provide a guideline for complication reporting in the body contouring literature. The Pittsburgh Body Contouring Complication Reporting System (PBCCRS) will aid in risk stratification of body contouring procedures and will decrease under-, over-, and nonreporting of complications. METHODS: The authors reviewed the literature for the terms "body contouring," "MWL," and "complications." Elimination criteria included: non-English language, case report, meta-analysis, outpatient, non-MWL, unclear demographics, N <30 and lack of numeric results. Data were analyzed in 2 groups: truncal contouring and extremity contouring. RESULTS: Eighty-nine papers were reviewed and 21 met inclusion criteria. The weighted mean rates as percentages for complications in the extremity group were: dehiscence (29.0), seroma (18.6), scarring (14.9), infection (8.8), lymphedema (7.8), hematoma (3.5), necrosis (1.9), deep venous thrombosis (DVT) or pulmonary embolism (PE) (0), and death (0). In the truncal group, weighted mean complication rates as percentages were: dehiscence (15.4), seroma (13.1), scarring (2.9), infection (9.4), lymphedema (1.3), hematoma (6.4), necrosis (7.2), DVT/PE (1.5), and death (0.6). Lymphedema was seldom reported, and suture extrusion was not reported in any selected papers. Weighted mean rates of DVT/PE in the extremity vs truncal contouring groups were significantly different. Differences in rates of scarring, lymphedema, and hematoma rates neared significance. CONCLUSIONS: Heterogeneity amongst selected studies is explained by variability in how complications are defined. The Pittsburgh Body Contouring Complication Reporting System provides suggested recommendations on complication reporting in massive weight loss body contouring surgery.

RESUMO

Channel flow of an incompressible fluid at Reynolds numbers above 2400 possesses a number of different spatially localized solutions that approach laminar flow far upstream and downstream. We use one such relative time-periodic solution, which corresponds to a spatially localized version of a Tollmien-Schlichting wave, to illustrate how the upstream and downstream asymptotics can be computed analytically. In particular, we show that for these spanwise uniform states the asymptotics predict the exponential localization that has been observed for numerically computed solutions of several canonical shear flows but never properly understood theoretically.

RESUMO

Purpose: Although transgender people are currently excluded from enlistment and discharged from service based on medical and psychological fitness policies, the current mental and physical health of transgender active-duty U.S. military personnel and veterans is poorly understood. The purpose of the current study was to investigate the military histories, lifetime mental and physical health diagnoses, and transgender transition-related health of transgender active-duty service members (ADSM) and veterans. Methods: Participants were recruited through private LGBT military and veteran organizational listservs, snowball sampling, and in-person recruitment to complete an anonymous and confidential self-administered online questionnaire. Results: A total of 106 transgender ADSM (n=55) and veterans (n=51) completed the questionnaire. Transgender veterans were significantly older (44 mean years vs. 29.5 mean years, t=-6.23, p<0.001). A greater percentage of veterans than ADSM reported depression (64.6% vs. 30.9%, χ2=11.68, p=0.001) and anxiety (41.3% vs. 18.2%, χ2=6.54, p=0.011). In addition, 15.9% of veterans versus 1.8% of ADSM (χ2=6.53, p=0.011) had been diagnosed with a substance abuse disorder. There were no significant differences in lifetime physical health conditions; however, veterans reported a higher body-mass index than ADSM (28.4 vs. 24.9, t=-3.85, p<0.001). For both groups, mental and physical health problems were positively correlated with age and years of military service (r=0.37-0.84, p<0.01). There were no significant differences between groups in transgender transition-related health. Conclusion: Our data represent the first descriptive statistics of lifetime mental and physical health issues among transgender ADSM and veterans. Data indicate that transgender ADSM report fewer lifetime mental and physical health problems than transgender veterans. Taken together, our findings suggest that more research, specifically among transgender ADSM, is needed to challenge the exclusion of transgender persons from U.S. military service based on the presumption of poor mental or physical health.
