This study aims to characterize suicide and associated disparities among persons experiencing homelessness (PEH).We reviewed suicide victims in the National Violent Death Reporting System (NVDRS) from 2003 to 2018 and compared factors surrounding suicides of PEH to factors of housed victims. We also utilized the Point-in-Time (PIT) survey (2010-2018), and census population estimates, to estimate suicide rates among PEH and the wider population.1.1% of suicide victims were described as experiencing homelessness at the time of their deaths, a value that is disproportional given the overall homeless rates of 0.2% in the past decade. Compared to nonhomeless victims, PEH were more likely to be younger, Black, male, and nonveterans. PEH were significantly more likely to have an identified alcohol/substance use disorder. PEH were half as likely to die via firearm and were more likely to die in natural areas, motels, and the streets. PEH were significantly more likely to have a history of suicidal thoughts, a history of suicide attempts, and a history of disclosure of intent, particularly to health care workers.PEH are disproportionately overrepresented among all suicide victims, but the circumstances surrounding their deaths create opportunity for targeted interventions.

The COVID-19 pandemic has brought many challenges including barriers to delivering high-quality surgical care and follow-up while minimizing the risk of infection. Telehealth has been increasingly utilized for post-operative visits, yet little data exists to guide surgeons in its use. We sought to determine safety and efficacy of telehealth follow-up in patients undergoing cholecystectomy during the global pandemic at a VA Medical Center (VAMC).This was a retrospective review of patients undergoing cholecystectomy at a level 1A VAMC over a 2-year period from August 2019 to August 2021. Baseline demographics, post-operative complications, readmissions, emergency department (ED) visits and need for additional procedures were reviewed. Patients who experienced a complication prior to discharge, underwent a concomitant procedure, had non-absorbable skin closure, had new diagnosis of malignancy or were discharged home with drain(s) were ineligible for telehealth follow-up and excluded.Over the study period, 179 patients underwent cholecystectomy; 30 (17%) were excluded as above. 20 (13%) missed their follow-up, 52 (35%) were seen via telehealth and 77 (52%) followed-up in person. There was no difference between the two groups regarding baseline demographics or intra-operative variables. There was no significant difference in post-operative complications [4 (8%) vs 6 (8%), p 0.99], ED utilization [5 (10%) vs 7 (9%), p = 0.78], 30-day readmission [3 (6%) vs 6 (8%), p = 0.74] or need for additional procedures [2 (4%) vs 4 (5%), p = 0.41] between telehealth and in-person follow-up.Telehealth follow-up after cholecystectomy is safe and effective in Veterans. There were no differences in outcomes between patients that followed up in-person vs those that were seen via phone or video. Routine telehealth follow-up after uncomplicated cholecystectomy should be considered for all patients.

Perforation is a known complication of endoscopic resection and has been managed with endoscopic defect closure, antibiotics and close observation. Closure of duodenal perforations are more challenging due to the presence of gastric and pancreaticobiliary secretions. The use of endoluminal vacuum therapy (EVT) to divert flow and aid closure is increasingly prevalent and may avoid high-risk surgery. We describe the use of endoluminal vacuum closure to salvage an iatrogenic duodenal perforation in a 57-year-old male who underwent an endoscopic mucosal resection of a 35-mm polypoid lesion on the posterior wall of the second portion of the duodenum. The endoluminal wound vac successfully controlled leakage and allowed defect closure. EVT is an emerging technique that can effectively manage complicated injuries throughout the GI tract and may allow enhanced recovery by avoiding surgical salvage and its associated morbidity and mortality.

Enteral access is required for a variety of reasons from neuromuscular disorders to dysphagia. Gastrostomy tubes (GTs) can be placed endoscopically, surgically, or radiographically and complications include infection, bleeding, leakage and unintentional removal. Routine post-procedural follow-up is limited by inconsistent guidelines and management by different specialty teams. We established a dedicated GT clinic to provide continuity of care and prophylactic GT exchange. We hypothesized that patients followed in the GT clinic would have reduced Emergency Department (ED) utilization.A retrospective review of patients who underwent GT placement from January 2010 to January 2020 was conducted. Baseline demographics, indications for GT placement, number and reason for ED visits and utilization of a multidisciplinary GT clinic were studied.A total of 97 patients were included. The most common indication for placement was dysphagia (88, 91%) and the most common primary diagnosis was head and neck malignancy (51, 51%). The GT clinic is a multidisciplinary clinic staffed by surgeons and residents, dieticians, and wound care specialists and cared for 16 patients in this study. Three patients (19%) in the GT clinic group required ED visits compared to 44 (54%) in the standard of care (SOC) group (p 0.05). There was an average of 0.9 ED visits per patient (range 0-7) in the GT clinic group vs 1.6 ED visits per patient (range 0-20) in the SOC group (p = 0.34). Feeding tubes were prophylactically exchanged an average of 7 times per patient in the GT clinic group vs 3 times per patient in the SOC group (p 0.05).A multidisciplinary clinic dedicated to GT care limits ED visits for associated complications by more than 50%. Follow-up in a dedicated clinic with prophylactic tube exchange decreases ED visits and should be considered at facilities that care for patients with GTs.

Depression can have debilitating effects on patients with a chronic morbid disease, in particular, cancer. It has been found that patients with a depressive disorder have a poorer prognosis and increased mortality. There is a debate as to whether the treatment of the depressive disorder is beneficial to these patients. Studies demonstrate varying results with pharmacotherapy and behavioral therapy. All cancer patients should be periodically assessed for depressive disorder and the symptoms not dismissed as part of their cancer presentation due to the increased mortality.

We demonstrate the design and fabrication of a Ag/PEDOT:PSS/MnO2 layer by layer structure for high performance flexible supercapacitors (SCs). This is a unique design combining Ag-nanowires and PEDOT:PSS-nanopillars as current collectors in SCs. In this sandwich-like structure, electrons can be easily transferred through a networked structure of Ag-nanowires to PEDOT:PSS-nanopillars and finally to the MnO2 layer and vice versa. This scheme provides excellent specific capacitances of 862 F g−1 (based on MnO2) at a current density of 2.5 A g−1 and robust long-term cycling stability. Moreover, SCs fabricated based on this structure exhibit exceptional flexibility and bendability (less than 2% loss in specific capacitance even after 100 bends) and high energy and power densities. All wet processing methods of fabrication along with superior performance make these SCs very attractive for the next generation flexible energy storage systems.

This report demonstrates a simple, but efficient method to print highly ordered nanopillars without the use of sacrificial templates or any expensive equipment. The printed polymer structure is used as a scaffold to deposit electrode material (manganese dioxide) for making supercapacitors. The simplicity of the fabrication method together with superior power density and energy density make this supercapacitor electrode very attractive for the next-generation energy storage systems.

Background and Objectives: Laparoscopic surgery can be complicated by condensation and debris on the lens obscuring the visual field, increasing the risk of surgical error and injury to the patient. Despite, development of possible solutions, little is known regarding the quantitative measure of time lost during surgery because of an obscured visual field. Without this knowledge, the cost of laparoscopic lens fogging cannot be quantified and compared to the cost of antifogging devices. In the present study, we investigated the amount of time a laparoscope is withdrawn for cleaning during surgery. Methods: This was a prospective, observational study of patients (n = 52) who underwent laparoscopic surgery at Florida Hospital Celebration Health. Patient's age, gender, and body mass index, operative time, wound class, estimated blood loss, type of procedure, and complication (if any) were collected. In addition, intraoperative information on the number of times and total amount of time the laparoscope was withdrawn because of obscured visual field were recorded. Results: Eighty-two percent (43) of the procedures required laparoscope withdrawal because of fogging. Increased operative time, increased blood loss, and patient age correlated with the number of times (P < .05) and amount of time (P < .05) the laparoscope was withdrawn. Discussion: There was a significant correlation between increased laparoscope withdrawal because of an obscured visual field with increased EBL, operative time, and patient age. Possible explanations include change in body composition with age, the increased viewing angles required for more complex procedures, and increasing intraoperative effect on the surgeon of the poor visual field caused by fogging and debris.
