Permanent Supportive Housing and Specialized Co-Occurring Disorders Wraparound Services for Homeless Individuals

Abstract Objective: Among individuals experiencing chronic homelessness, there is a high rate of co-occurring mental health and substance use, which has traditionally been addressed through the delivery of permanent supportive housing along with substance use and mental health services. However, this population often has difficulty engaging in treatment for co-occurring disorders, which can result in exacerbation of symptoms and housing loss. Maintaining Independence and Sobriety Through Systems Integration, Outreach, and Networking (MISSION) is a co-occurring mental health and substance use wraparound approach that was pilot-tested alongside Permanent Supportive Housing (PSH) to improve treatment access and engagement. This pilot was part of a state plan to end homelessness in the Boston metro area. Methods: This open pilot study enrolled 136 individuals who were chronically homeless and offered one year of MISSION along with PSH. Program participants also received baseline and 6- and 12-month follow-up assessments. Results: At one-year follow-up, 82.4% of the program participants were housed in PSH. However, due to limited affordable housing in the Boston metro area, it took on average 6.20 months to house the program participants. Furthermore, while MISSION was feasible to implement alongside PSH, fidelity to the MISSION model was lower than expected. This pilot also examined the role of housing status on clinical outcomes and found that the program participants who were housed at the time of discharge displayed a statistically significant improvement in emergency room visits for mental health complaints, the Psychosis subscale of the Behavior and Symptom Identification Scale (BASIS-32), illegal drug use, and pharmacotherapy treatment. Conclusions: This pilot study demonstrated that systematically integrating PSH and MISSION can improve access and engagement in care, housing retention, and mental health outcomes. Despite the preliminary success and while taking into account the limitations of the open single-group pre/post design, this study also identified the lack of affordable housing as a potential barrier to placement as well as the critical role of housing for improved clinical outcomes. Randomized controlled trials are needed to test MISSION with PSH as well as perhaps PSH with and without MISSION to tease apart the effects of integrating both approaches simultaneously.
Audição Musical Afetiva: Recurso a expressões faciais para recomendação musical

E uma tarefa ardua democratizar a musica em funcao dos gostos pessoais de cada ouvinte. Os processos de recomendacao musical tratam os consumidores de musica de forma impessoal baseando as suas propostas em similaridades musicais nao contemplando o contexto emocional dos auditores. Este estudo propoe-se relacionar as emocoes demonstradas pelas expressoes faciais dos ouvintes quando sujeitos a audicao de varios temas musicais com a afirmacao do seu gosto pessoal por cada musica. Um conjunto de 26 participantes foi exposto a audicao de 17 excertos musicais cujas partes continham o verso e o refrao do tema. Foi usado um Software Development Kit que permitiu com o auxilio de uma webcam registar as expressoes faciais de cada participante e obter os dados sobre as emocoes presentes ao longo do tempo em cada peca audio apresentada. Foi recolhida uma apreciacao por intermedio de uma escala de tipo likert de sete pontos sobre o prazer associado a audicao de cada tema por cada participante. Os resultados preliminares sugerem alguma apatia na demonstracao emocional sendo por vezes antagonicos no que respeita a uma interpretacao visual comum das expressoes.
A History of Previous Severe Injury and Health-Related Quality of Life Among Former Collegiate Athletes.

CONTEXT Empirical evidence supports the idea that previous severe injuries in former collegiate athletes may adversely affect their ability to participate in daily activities later in life, which may then decrease their health-related quality of life (HRQOL). OBJECTIVE To assess the influences of previous severe injuries on the HRQOL of former National Collegiate Athletic Association (NCAA) athletes. DESIGN Cross-sectional study. SETTING Online survey. PATIENTS OR OTHER PARTICIPANTS A total of 171 former NCAA collegiate athletes (69 men, 102 women; age = 29.7 ± 3.9 years, height = 171.5 ± 10.4 cm, mass = 76.4 ± 12.9 kg) participated. All individuals completed a demographics questionnaire and the Short Form-36 version 2 (SF-36v2) Health Survey via Qualtrics. MAIN OUTCOME MEASURE(S) The dependent variables were the physical composite and mental composite summary scores and the 8 subscales of the SF-36v2. The independent variable was the presence of previous severe injury (history of a severe injury or no history of a severe injury during collegiate athletics). Two multivariate analyses of variance were conducted. The first multivariate analysis of variance was conducted for the 8 SF-36v2 subscales and the second for the 2 summary scores. RESULTS For the summary scores and all 8 SF-36v2 subscales, the responses were worse for the 103 former collegiate athletes who sustained a previous severe injury compared with the 68 who did not sustain a severe injury. The largest difference between groups was for the physical composite score, with a mean difference of 15.8 points (1.5 standard deviations worse than the US population); the physical functioning subscale demonstrated a mean difference of 12.9 points (1.3 standard deviations worse than the US population). CONCLUSIONS A majority of the athletes in our sample had experienced a severe injury. Based on these data, previous severe injuries had a negative influence on the HRQOL of former NCAA collegiate athletes.
RhoGDIβ affects HeLa cell spindle orientation following UVC irradiation

The molecular signals that regulate mitotic spindle orientation to determine the proper division axis play a critical role in the development and maintenance of tissue homeostasis. However, deregulation of signaling events can result in spindle misorientation, which in turn can trigger developmental defects and cancer progression. Little is known about the cellular signaling pathway involved in the misorientation of proliferating cells that evade apoptosis after DNA damage. In this study, we found that perturbations to spindle orientation were induced in ultraviolet C (UVC)‐irradiated surviving cells. N‐terminal truncated Rho GDP‐dissociation inhibitor β (RhoGDIβ), which is produced by UVC irradiation, distorted the spindle orientation of HeLa cells cultured on Matrigel. The short hairpin RNA‐mediated knockdown of RhoGDIβ significantly attenuated UVC‐induced misorientation. Subsequent expression of wild‐type RhoGDIβ, but not a noncleavable mutant, RhoGDIβ (D19A), again led to a relative increase in spindle misorientation in response to UVC. Our findings revealed that RhoGDIβ impacts spindle orientation in response to DNA damage.
Identifying molecular contributors to autofluorescence of neoplastic and normal colon sections using excitation-scanning hyperspectral imaging

Abstract. Autofluorescence, the endogenous fluorescence present in cells and tissues, has historically been considered a nuisance in biomedical imaging. Many endogenous fluorophores, specifically, collagen, elastin, nicotinamide adenine dinucleotide, and flavin adenine dinucleotide (FAD), are found throughout the human body. In fluorescence imaging scenarios, these signals can be prohibitive as they can outcompete signals introduced for diagnostic purposes. However, autofluorescence also contains information that has diagnostic value. Recent advances in hyperspectral imaging have allowed the acquisition of significantly more data in a shorter time period by scanning the excitation spectra of fluorophores. The reduced acquisition time and increased signal-to-noise ratio allow for separation of significantly more fluorophores than previously possible. We propose to utilize excitation-scanning hyperspectral imaging of autofluorescence to differentiate neoplastic lesions from surrounding non-neoplastic “normal” tissue. The spectra of isolated autofluorescent molecules are obtained using a custom inverted microscope (TE-2000, Nikon Instruments) with an Xe arc lamp and thin-film tunable filter array (VersaChrome, Semrock, Inc.). Scans utilize excitation wavelengths from 360 to 550 nm in 5-nm increments. The resultant molecule-specific spectra are used to analyze hyperspectral image stacks from normal and neoplastic colorectal tissues. Due to a limited number of samples, neoplastic tissues examined here are a pool of both colorectal adenocarcinoma and adenomatous polyps. The hyperspectral images are analyzed with ENVI software and custom MATLAB scripts, including linear spectral unmixing. Initial results indicate the ability to separate signals of endogenous fluorophores and measure the relative concentrations of fluorophores among healthy and diseased states, in this case, normal colon versus neoplastic colon. These results suggest pathology-specific changes to endogenous fluorophores can be detected using excitation-scanning hyperspectral imaging. Future work will focus on expanding the library of pure molecules, exploring histogram distance metrics as a means for identifying deviations in spectral signatures, and examining more defined disease states.
Soft drink consumption during and following exercise in the heat elevates biomarkers of acute kidney injury.

The purpose of this study was to test the hypothesis that consuming a soft drink (i.e., a high-fructose, caffeinated beverage) during and following exercise in the heat elevates biomarkers of acute kidney injury (AKI) in humans. Twelve healthy adults drank 2 liters of an assigned beverage during 4 h of exercise in the heat [35.1 (0.1)°C, 61 (5)% relative humidity] in counterbalanced soft drink and water trials, and ≥1 liter of the same beverage after leaving the laboratory. Stage 1 AKI (i.e., increased serum creatinine ≥0.30 mg/dl) was detected at postexercise in 75% of participants in the Soft Drink trial compared with 8% in Water trial ( P = 0.02). Furthermore, urinary neutrophil gelatinase-associated lipocalin (NGAL), a biomarker of AKI, was higher during an overnight collection period after the Soft Drink trial compared with Water in both absolute concentration [6 (4) ng/dl vs. 5 (4) ng/dl, P < 0.04] and after correcting for urine flow rate [6 (7) (ng/dl)/(ml/min) vs. 4 (4) (ng/dl)/(ml/min), P = 0.03]. Changes in serum uric acid from preexercise were greater in the Soft Drink trial than the Water trial at postexercise ( P < 0.01) and 24 h ( P = 0.05). There were greater increases from preexercise in serum copeptin, a stable marker of vasopressin, at postexercise in the Soft Drink trial ( P < 0.02) than the Water trial. These findings indicate that consuming a soft drink during and following exercise in the heat induces AKI, likely via vasopressin-mediated mechanisms.
The replicability of ICD-11 complex post-traumatic stress disorder symptom networks in adults.

BACKGROUND The ICD-11 includes a new disorder, complex post-traumatic stress disorder (CPTSD). A network approach to CPTSD will enable investigation of the structure of the disorder at the symptom level, which may inform the development of treatments that target specific symptoms to accelerate clinical outcomes.AimsWe aimed to test whether similar networks of ICD-11 CPTSD replicate across culturally different samples and to investigate possible differences, using a network analysis. METHOD We investigated the network models of four nationally representative, community-based cross-sectional samples drawn from Germany, Israel, the UK, and the USA (total N = 6417). CPTSD symptoms were assessed with the International Trauma Questionnaire in all samples. Only those participants who reported significant functional impairment by CPTSD symptoms were included (N = 1591 included in analysis; mean age 43.55 years, s.d. 15.10, range 14-99, 67.7% women). Regularised partial correlation networks were estimated for each sample and the resulting networks were compared. RESULTS Despite differences in traumatic experiences, symptom severity and symptom profiles, the networks were very similar across the four countries. The symptoms within dimensions were strongly associated with each other in all networks, except for the two symptom indicators assessing aspects of affective dysregulation. The most central symptoms were 'feelings of worthlessness' and 'exaggerated startle response'. CONCLUSIONS The structure of CPTSD symptoms appears very similar across countries. Addressing symptoms with the strongest associations in the network, such as negative self-worth and startle reactivity, will likely result in rapid treatment response.Declaration of interestA.M. and M.C. were members of the World Health Organization (WHO) ICD-11 Working Group on the Classification of Disorders Specifically Associated with Stress, reporting to the WHO International Advisory Group for the Revision of ICD-10 Mental and Behavioural Disorders.

Mechanism-based pain management in chronic pancreatitis – is it time for a paradigm shift?

ABSTRACT Introduction: Pain is the most common symptom in chronic pancreatitis and treatment remains a challenge. Management of visceral pain, in general, is only sparsely documented, and treatment in the clinic is typically based on empirical knowledge from somatic pain conditions. This may be problematic, as many aspects of the neurobiology differ significantly from somatic pain, and organs such as the gut and liver play a major role in tolerability to analgesics. On the other hand, clinical awareness and new methods for quantitative assessment of pain mechanisms, will likely increase our understanding of the visceral pain system and guide more individualized pain management. Areas covered: This review includes an overview of known pain mechanisms in chronic pancreatitis and how to characterize them using quantitative sensory testing. The aim is to provide a mechanism-oriented approach to analgesic treatment, including treatment of psychological factors affecting pain perception and consideration of side effects in the management plan. Expert opinion: A mechanism-based examination and profiling of pain in chronic pancreatitis will enable investigators to provide a well-substantiated approach to effective management. This mechanism-based, individualized regime will pave the road to better pain relief and spare the patient from unnecessary trial-and-error approaches and unwanted side effects.
Outcomes of Wound Healing and Limb Loss After Transmetatarsal Amputation in the Presence of Peripheral Vascular Disease

&NA; Transmetatarsal amputation (TMA) is the procedure of choice in treating forefoot gangrene and infection. Foot and ankle and vascular surgeons work closely together in limb salvage, but little is known about the timing of vascular intervention to achieve a healed amputation site. This study retrospectively looked at 153 patients with peripheral vascular disease who underwent TMA with a minimum of a 3‐year follow‐up. A total of 102 patients received vascular intervention: 79 endovascular and 23 open bypass. The primary focus of this study was to look at the timing of vascular intervention, incidence of wound healing, and incidence of limb loss. There was an overall 44% rate of limb loss. Patients who underwent open bypass did better than those who underwent endovascular intervention with a lower incidence of limb loss (87% compared with 51%), and quicker time to wound healing. The timing of vascular intervention, performed either before or after TMA, had no association with wound healing or limb loss. Similarly, the time interval between vascular intervention and TMA had no association with wound healing or limb loss. Comorbidities, including end‐stage renal disease on hemodialysis, hyperlipidemia, and congestive heart failure, showed a significant association with TMA stump nonhealing and limb loss. Body mass index ≥30, end‐stage renal disease on hemodialysis, and hyperlipidemia were all risk factors for limb loss.

Clinical Presentations of Melanoma in African Americans, Hispanics, and Asians.

BACKGROUND Skin cancer has traditionally been studied in Caucasian skin. Although it does occur with increased relative frequency in Caucasians, patients with skin of color suffer from elevated morbidity and mortality when diagnosed with skin cancer. OBJECTIVE To detail the unique demographic, clinical, and genetic features of melanoma in patients with skin of color, including Hispanic, African American, and Asian patients. MATERIALS AND METHODS A PubMed search was conducted spanning dates 1947 to June 2017. A total of 246 articles were screened, from which 69 were included in this review. RESULTS Relative to Caucasians, melanoma has unique demographic, clinical, and genetic features in African Americans, Hispanics, and Asians that include gender and subtype predominance. CONCLUSION Familiarization with these unique presentations of skin cancer in skin of color is imperative to accurate identification and treatment of cutaneous malignancies in these populations and ultimately to improved disease-related outcomes.
Sustained Improvement in Type 2 Diabetes Mellitus is Common After Treatment of Hepatitis C Virus With Direct-acting Antiviral Therapy

Goals: To determine whether diabetic patients with hepatitis C virus (HCV) treated with direct-acting antiviral agents have improved diabetes, accounting for change in both hemoglobin A1c (HbA1c) and diabetes medications, and whether any improvement was sustained. Background: HCV infection is associated with an increased risk of diabetes, with improvement in glycemic control after eradication. There remains uncertainty about the durability and magnitude of this effect. Study: HbA1c and diabetes medications were recorded at 6-month intervals for 1.5 years pretreatment and posttreatment for 122 patients. Subjects were classified as having improved diabetes if there was a decrease in HbA1c≥0.5% with no increase in diabetes medications or a decrease in diabetes medications with a stable HbA1c. Results: HbA1c at the nearest time point before treatment was 8.4%±1.9%, compared with 7.8%±1.7% after treatment, a mean difference of 0.6% [95% CI (0.2, 0.9), P<0.01]. A linear mixed effects model incorporating each subject’s repeated measurements over time also demonstrated a reduction after treatment of 0.5% [95% CI, (0.3, 0.8), P<0.001]. Accounting for both HbA1c and diabetes medications, 42 of 122 (34%) had an improvement in diabetes after HCV treatment, and 20 of 28 (71%) of these subjects sustained improvement at 1.5 years follow-up. Prescription of insulin was associated with improved diabetes. Conclusions: Treatment of HCV with direct-acting antiviral agents was associated with improved diabetes in a significant portion of patients with an average reduction in HbA1c of clinically significant magnitude. Among responders, this effect was sustained over 1.5 years of follow-up.
Drug design strategies for Cushing’s syndrome

ABSTRACT Introduction: Cushing’s syndrome (CS) is a metabolic disorder caused by chronic hypercortisolism. CS is associated with cardiovascular, metabolic, skeletal and psychological dysfunctions and can be fatal if left untreated. The first-line treatment for all forms of CS is a surgery. However, medical therapy has to be chosen if surgical resection is not an option or is deemed ineffective. Currently available therapeutics are either not selective and have side effects or are only available as an injection (pasireotide). Areas covered: The authors discuss the recent drug developments for the medical treatment of CS through two validated molecular targets. Specifically, the authors look at selective inhibitors of CYP11B1 that reduce cortisol production by inhibiting steroid 11beta-hydroxylase and glucocorticoid receptor (GR) antagonists that interrupt cortisol-mediating transcriptional regulation of related genes. Expert opinion: Patients with CS have limited treatment options; indeed, there is an unmet need for new compounds that target CYP11B1 selectively versus several steroidogenic enzymes and/or GR-signaling pathways. The complexity of steroid biosynthesis and signaling requires the application of structure-based drug discovery techniques that use molecular targets and highly similar off-targets. Significant differences in steroidogenesis between humans and other species necessitates caution over the choice of in vivo model for the preclinical evaluation of future potential compounds.
Roughness effects of diatomaceous slime fouling on turbulent boundary layer hydrodynamics

Abstract Biofilm fouling significantly impacts ship performance. Here, the impact of biofilm on boundary layer structure at a ship-relevant, low Reynolds number was investigated. Boundary layer measurements were performed over slime-fouled plates using high resolution particle image velocimetry (PIV). The velocity profile over the biofilm showed a downward shift in the log-law region (ΔU+), resulting in an effective roughness height (ks) of 8.8 mm, significantly larger than the physical thickness of the biofilm (1.7 ± 0.5 mm) and generating more than three times as much frictional drag as the smooth-wall. The skin-friction coefficient, Cf, of the biofilm was 9.0 × 10−3 compared with 2.9 × 10−3 for the smooth wall. The biofilm also enhances turbulent kinetic energy (tke) and Reynolds shear stress, which are more heterogeneous in the streamwise direction than smooth-wall flows. This suggests that biofilms increase drag due to high levels of momentum transport, likely resulting from protruding streamers and surface compliance.
