Utility of NICaS Non-Invasive Hemodynamic Monitoring in Critically Ill Patients with COVID-19.

(1) Background: COVID-19 presented many challenges to effective treatments, such as managing cardiovascular insufficiency while mitigating risks to healthcare providers. This study utilized NICaS, a non-invasive hemodynamic monitor that provides advanced data via whole-body impedance analysis. We investigated the associated trends in hemodynamic parameters obtained by the NICaS device and their correlation with in-hospital all-cause mortality during COVID-19 hospitalization in the intensive care unit. (2) Methods: Data from 29 patients with COVID-19 admitted to the intensive care unit and monitored with NICaS between April 2020 and February 2021 were analyzed retrospectively. (3) Results: Decreasing cardiac output and cardiac power were significantly associated with death. Total peripheral resistance was significantly increasing in non-survivors as was total body water percentage. Those admitted with a heart rate above 90 beats per minute had a significantly reduced survival. (4) Conclusions: Non-invasive hemodynamic monitoring via the NICaS device is simple and effective in evaluating critically ill patients with COVID-19 and may help guide clinical management via remote monitoring. Controlling tachycardia may help ensure adequate oxygen supply-demand ratio. A hint toward a beneficiary effect of a restrictive fluid balance may be observed.

"When Will All of This End?": A 65-Year-Old Man With Amyotrophic Lateral Sclerosis and Psychiatric Distress.

Patients with amyotrophic lateral sclerosis (ALS) are impacted both physically and psychiatrically during their illness. Emotional distress (ie, anxiety, depression, stress) is common in patients diagnosed with ALS, as prognosis is poor and there are very few effective treatments. The progression of symptoms is unpredictable, and all cases are terminal. Neuropsychiatric symptoms are also increasingly recognized as part of ALS symptomatology. There are currently no empirically supported interventions or best practices for adjustment to ALS. This case presents both the psychological and pharmacologic aspects of caring for a patient with ALS. Psychotherapy utilized a cognitive behavioral therapy-informed approach, and pharmacotherapy was tailored to the specific needs of the patient. We explore how these approaches impacted our patient, as well as how ALS-specific challenges presented throughout the course of treatment.

Evaluation, Treatment, and Referral of Treatment-Resistant Depression in Primary Care.

The Psychiatric Consultation Service at Massachusetts General Hospital sees medical and surgical inpatients with comorbid psychiatric symptoms and conditions. During their twice-weekly rounds, Dr Stern and other members of the Consultation Service discuss diagnosis and management of hospitalized patients with complex medical or surgical problems who also demonstrate psychiatric symptoms or conditions. These discussions have given rise to rounds reports that will prove useful for clinicians practicing at the interface of medicine and psychiatry.Prim Care Companion CNS Disord. 2023;25(4):22f03438.

In vivo detection of bile duct pre-cancer with endoscopic light scattering spectroscopy.

Bile duct cancer is the second most common primary liver cancer, with most diagnoses occurring in the advanced stages. This leads to a poor survival rate, which means a technique capable of reliably detecting pre-cancer in the bile duct is urgently required. Unfortunately, radiological imaging lacks adequate accuracy for distinguishing dysplastic and benign biliary ducts, while endoscopic techniques, which can directly assess the bile duct lining, often suffer from insufficient sampling. Here, we report an endoscopic optical light scattering technique for clinical evaluation of the malignant potential of the bile duct. This technique employs an ultraminiature spatial gating fiber optic probe compatible with cholangioscopes and endoscopic retrograde cholangiopancreatography (ERCP) catheters. The probe allowed us to investigate the internal cellular composition of the bile duct epithelium with light scattering spectroscopy (LSS) and phenotypic properties of the underlying connective tissue with diffuse reflectance spectroscopy (DRS). In a pilot in vivo double-blind prospective study involving 29 patients undergoing routine ERCP procedures, the technique detected malignant transformation with 97% accuracy, showing that biliary duct pre-cancer can be reliably identified in vivo non-invasively.

Treating PTSD and Alcohol Use Disorder: Concurrent Cognitive Processing Therapy and Psychopharmacology.

Comorbidity is common with posttraumatic stress disorder, and alcohol use disorder (AUD) is among the most common co-occurring disorders. When viewed through the lens of avoidance behaviors, AUD can shape an individual's response to distressing trauma reminders by dulling the emotional response and promoting disengagement from the traumatic memory. Over time, this response strengthens posttraumatic distress by reinforcing the belief that traumatic memories and their emotional responses are themselves dangerous and intolerable. In turn, this belief may impede treatment progress. Concurrent trauma-focused therapy and AUD treatment can serve to establish more adaptive coping strategies. Reducing reliance on alcohol for coping while engaging safely and effectively with trauma memories allows the individual to process the memories, build tolerance to emotional distress, and ultimately reframe maladaptive trauma-related beliefs and decrease the intensity of reactions. This case presents concurrent psychopharmacology and cognitive processing therapy for co-occurring posttraumatic stress disorder and AUD. We explore how alcohol use, and emotional avoidance more broadly, become targets for change.

Treatment of Overthinking: A Multidisciplinary Approach to Rumination and Obsession Spectrum.

Classic psychiatry patients are rare; real-world patients tend to have overlapping features of multiple disorders. Striving for diagnostic certainty, and treatments aimed at tentative diagnoses, often fail these patients. In such cases, tolerating diagnostic ambiguity and "treating the symptoms" can sometimes be transformative. An important symptom, often undertreated in a diagnosis-based approach, is rumination. We present a case study of a woman who, after 20 years of treatment failure, achieved significant symptom relief when her primary complaint-"labored thinking"-was targeted specifically. However, because no seriously ill person has only 1 symptom, 6 clinicians from different subdisciplines will discuss the patient's other issues, ones that an overfocus on rumination might leave out.

Psychological Dimensions of Palliative Care Consultation: Approaches to Seriously Ill Patients at the End of Life.

Mental health clinicians often hear seriously ill patients ask the unanswerable: Why did this happen? What is the meaning of my suffering? In the inpatient setting, general medical ward, or oncology unit, patients are confronted with their mortality in new, urgent ways. Palliative medicine, or the specialized, comprehensive care of patients facing a life-limiting illness, occupies a unique and liminal space. Although often practiced by clinicians with non-mental health training backgrounds, there exists ample psychological content to be explored in the palliative care encounter. In this article, we present the case of a husband and international businessperson who experienced terminal complications from an advanced stage lung cancer. His illness was not responsive to multiple cancer-directed treatments, and he developed respiratory failure requiring high levels of supplemental oxygen support, from which he was unable to wean. Palliative care consultation was sought with the multiple objectives of ameliorating his severe death anxiety and persistent dyspnea as well as assisting in the clarification of his end-of-life wishes. Our goal with this case presentation and related discussion is to introduce the psychological aspects of palliative medicine to psychiatrists and psychotherapists.

ERCP within 6 or 12 h for acute cholangitis: a propensity score-matched analysis.

BACKGROUND: The optimal timing of biliary drainage by endoscopic retrograde cholangiopancreatography (ERCP) for patients with acute cholangitis remains controversial. The aim of our study was to determine if ERCP performed within 6 or 12 h of presentation was associated with improved clinical outcomes. METHODS: Medical records for all patients with acute cholangitis who underwent ERCP at our institution between 2009 and 2018 were reviewed. Outcomes were compared between those who underwent ERCP within or after 12 h using propensity score framework. Our primary outcome was length of hospitalization. Secondary outcomes included in-hospital mortality, adverse events, ERCP failure, length of ICU stay, organ failure, recurrent cholangitis, and 30-day readmission. In secondary analysis, outcomes for ERCP done within or after 6 h were also compared. RESULTS: During study period, 487 patients with cholangitis were identified, of whom 147 had ERCP within 12 h of presentation. Using propensity score matching, we selected 145 pairs of patients with similar characteristics. Length of hospitalization was similar between ERCP within or after 12 h (135.9 vs 122.1 h, p 0.094). No difference was noted in mortality, ERCP failure, adverse events, need and length of ICU stay, and recurrent cholangitis. However, 30-day readmission rates were lower when ERCP within 12 h (7.6 vs 15.2, p 0.042). No significant difference was noted in aforementioned outcomes between ERCP performed within or after 6 h. CONCLUSIONS: ERCP performed within 6 h or 12 h of presentation was not associated with superior clinical outcomes, however, may result in reduced re-hospitalization.

Organoid Sensitivity Correlates with Therapeutic Response in Patients with Pancreatic Cancer.

PURPOSE: Pancreatic ductal adenocarcinoma (PDAC) remains a significant health issue. For most patients, there are no options for targeted therapy, and existing treatments are limited by toxicity. The HOPE trial (Harnessing Organoids for PErsonalized Therapy) was a pilot feasibility trial aiming to prospectively generate patient-derived organoids (PDO) from patients with PDAC and test their drug sensitivity and correlation with clinical outcomes. EXPERIMENTAL DESIGN: PDOs were established from a heterogeneous population of patients with PDAC including both basal and classical PDAC subtypes. RESULTS: A method for classifying PDOs as sensitive or resistant to chemotherapy regimens was developed to predict the clinical outcome of patients. Drug sensitivity testing on PDOs correlated with clinical responses to treatment in individual patients. CONCLUSIONS: These data support the investigation of PDOs to guide treatment in prospective interventional trials in PDAC.

Psychotherapy for Functional Neurological (Conversion) Disorder: A Case Bridging Mind, Brain, and Body.

Functional neurologic (conversion) disorder (FND) is a core neuropsychiatric condition directly at the intersection of psychiatry and neurology. Over the past several decades, renewed interest in FND has been catalyzed by use of a "rule-in" diagnostic approach leveraging positive clinical signs specific for the diagnosis. In parallel, advances have occurred in identifying mechanisms, etiologic factors, and evidence-based treatments for this population. While "one size fits all" formulations of the "conversion" of psychological distress into physical symptoms are no longer widely accepted, emotion processing and related psychological constructs (eg, alexithymia, dissociation, threat avoidance) remain central to the conceptual understanding of FND. Furthermore, the biopsychosocial model (foundational to psychiatry) is the prevailing model through which to guide longitudinal treatment, with psychotherapy as an emerging first line intervention for FND. Nonetheless, there is a striking dearth of psychotherapists and mental health providers more broadly that feel well versed in the clinical assessment and management of patients with FND. In this article, we seek to address this gap by presenting the psychotherapy treatment narrative of a woman experiencing paroxysmal functional speech and gait disorder symptoms who had a positive clinical outcome. Our goal with this case presentation and related discussion is to increase the proficiency of psychotherapists in providing treatment to patients with FND.

Telenutrition for Inflammatory Bowel Disease: A Tipping Point for Dietary Wellness.

Inflammatory bowel disease (IBD), Crohn's disease and ulcerative colitis, cause inflammation of the digestive tract. It is estimated that about three million Americans and, globally, over six million individuals, suffer from IBD. While most physicians, especially gastroenterologists, are experts in the function and pathology of the gastrointestinal tract, factors such as nutrition science education and training, bandwidth, culture, language, and the longitudinal nature of dietary care, represent some of the barriers to receiving optimal nutritional guidance. Remote dietary expert counseling, an emerging solution that has been further highlighted by the COVID-19 pandemic, can improve IBD patients' nutritional status, avoid food triggers, and reduce the frequency and severity of exacerbations.

Two-photon polymerization nanofabrication of ultracompact light scattering spectroscopic probe for detection of pre-cancer in pancreatic cyst.

Pancreatic cancer has one of the worst survival rates of all major cancers, with pancreatic cystic lesions accounting for one in three pancreatic surgeries. The current gold-standard for diagnosis of pancreatic cyst malignancy is based on the endoscopic ultrasound guided fine-needle aspiration (EUS-FNA) procedure, which suffers from a low accuracy in detecting malignancy. Here we present the design and two-photon polymerization based fabrication of refractive and reflective non-contact probes, capable of rapid surveillance of the entire internal cyst surface-an advance over the contact probe we recently developed that allowed, for the first time, reliable evaluation of pancreatic cyst malignant potential in vivo. We employed a novel two-photon polymerization technique, which allows direct laser-writing to an accuracy of tens of nanometers, to fit the probe within the 540 micrometer internal diameter EUS-FNA needle. The newly constructed probes show excellent separation of the illumination and collection beams, essential for proper operation of the spatial gating method. These probes can be used clinically to perform rapid "optical biopsy", ultimately eliminating unnecessary pancreatic surgeries on benign cysts and dangerous delays in surgical removal of malignant cysts, improving patient prognosis and quality of life.

Preloaded 22-gauge fine-needle system facilitates placement of a higher number of fiducials for image-guided radiation therapy compared with traditional backloaded 19-gauge approach.

BACKGROUND AND AIMS: Image-guided radiation therapy (IGRT) often relies on EUS-guided fiducial markers. Previously used manually backloaded fiducial needles have multiple potential limitations including safety and efficiency concerns. Our aim was to evaluate the efficacy, feasibility, and safety of EUS-guided placement of gold fiducials using a novel preloaded 22-gauge needle compared with a traditional, backloaded 19-gauge needle. METHODS: This was a single-center comparative cohort study. Patients with pancreatic and hepatobiliary malignancy who underwent EUS-guided fiducial placement (EUS-FP) between October 2014 and February 2018 were included. The main outcome was the technical success of fiducial placement. Secondary outcomes were mean procedure time, fiducial visibility during IGRT, technical success of IGRT delivery, and adverse events. RESULTS: One hundred fourteen patients underwent EUS-FP during the study period. Of these, 111 patients had successful placement of a minimum of 2 fiducials. Fifty-six patients underwent placement using a backloaded 19-gauge needle and 58 patients underwent placement using a 22-gauge preloaded needle. The mean number of fiducials placed successfully at the target site was significantly higher in the 22-gauge group compared with the 19-gauge group (3.53 ± .96 vs 3.11 ± .61, respectively; P = .006). In the 22-gauge group, the clinical goal of placing 4 fiducials was achieved in 78%, compared with 23% in the 19-gauge group (P < .001). In univariate analyses, gender, age, procedure time, tumor size, and location did not influence the number of successfully placed fiducials. Technical success of IGRT with fiducial tracking was high in both the 19-gauge (51/56, 91%) and the 22-gauge group (47/58, 81%; P = .12). CONCLUSIONS: EUS-FP using a preloaded 22-gauge needle is feasible, effective, and safe and allows for a higher number of fiducials placed when compared with the traditional backloaded 19-gauge needle.

Single-use duodenoscope for ERCP performed by endoscopists with a range of experience in procedures of variable complexity.

BACKGROUND AND AIMS: Expert endoscopists previously reported ERCP outcomes for the first commercialized single-use duodenoscope. We aimed to document usability of this device by endoscopists with different levels of ERCP experience. METHODS: Fourteen "expert" (>2000 lifetime ERCPs) and 5 "less-expert" endoscopists performed consecutive ERCPs in patients without altered pancreaticobiliary anatomy. Outcomes included ERCP completion for the intended indication, rate of crossover to another endoscope, device performance ratings, and serious adverse events. RESULTS: Two hundred ERCPs including 81 (40.5%) with high complexity (American Society for Gastrointestinal Endoscopy grades 3-4) were performed. Crossover rate (11.3% vs 2.5%, P = .131), ERCP completion rate (regardless of crossovers) (96.3% vs 97.5%, P = .999), median ERCP completion time (25.0 vs 28.5 minutes, P = .130), mean cannulation attempts (2.8 vs 2.8, P = .954), and median overall satisfaction with the single-use duodenoscope (8.0 vs 8.0 [range, 1.0-10.0], P = .840) were similar for expert versus less-expert endoscopists, respectively. The same metrics were similar by procedural complexity except for shorter median completion time for grades 1 to 2 versus grades 3 to 4 (P < .001). Serious adverse events were reported in 13 patients (6.5%). CONCLUSIONS: In consecutive ERCPs including high complexity procedures, endoscopists with varying ERCP experience had good procedural success and reported high device performance ratings. (Clinical trial registration number: NCT04223830.).

Use of fully covered self-expanding metal biliary stents for managing endoscopic biliary sphincterotomy related bleeding.

Background and study aims Endoscopic biliary sphincterotomy (EBS) related-bleeding is a common adverse event related to endoscopic retrograde cholangiopancreatography (ERCP). Traditionally, endoscopic modalities such as epinephrine injection, cauterization, and balloon tamponade have been used for management. Recently, use of a fully covered self-expandable metal stent (FCSEMS) to manage EBS-related bleeding has gained popularity. However, data regarding its use are limited to small case series. Therefore, we aimed to evaluate the safety and efficacy of FCSEMS placement for the treatment of EBS-related bleeding. Patients and methods All patients referred to our center from October 2014 to November 2019 who had an FCSEMS placed for EBS-related bleeding were included. FCSEMS was placed either for primary control of bleeding or after failure of other traditional endoscopic hemostasis techniques at the discretion of the endoscopist. Data was collected regarding patient demographics, procedural characteristics, clinical and technical success rates of FCSEMS, as well as adverse events. Results A total of 97 patients underwent placement of FCSEMS for EBS-related bleeding, of which 76.3 % had immediate bleeding and 23.7 % had delayed bleeding. Mean age was 67.2 years and 47.4 % were males. Seven patients who had immediate EBS-related bleeding at index ERCP underwent other endoscopic therapies prior to placement of FCSEMS for rebleeding. The technical success rate for FCSEMS placement was 100 % and the rebleeding rate was 6.2 %. Four patients with FCSEMS placement developed pancreatitis and four had stent migration. Conclusions Our findings suggest that FCSEMS is a highly effective treatment modality for managing EBS-related bleeding and has an acceptable safety profile.

The Clinical and Metabolic Effects of Intragastric Balloon on Morbid Obesity and Its Related Comorbidities.

Obesity is becoming increasingly prevalent worldwide, and its metabolic sequelae lead to a significant burden on healthcare resources. Options for the management of obesity include lifestyle modification, pharmacological treatment, surgery, and endoscopic bariatric therapies (EBTs). Among these, EBTs are more effective than diet and lifestyle modification and are less invasive than bariatric surgery. In recent years, there have been significant advances in technologies pertaining to EBTs. Of all the available EBTs, there is a significant amount of clinical experience and published data regarding intragastric balloons (IGBs) because of their comparatively long development period. Currently, the United States Food and Drug Administration (FDA) has approved three IGBs, including Orbera (Apollo Endosurgery, Austin, TX, USA), ReShape Duo (ReShape Medical, San Clemente, CA, USA), and Obalon (Obalon Therapeutics, Carlsbad, CA, USA). The aim of this review is to summarize the available literature on the efficacy of IGBs in weight loss and their impact on obesity-related metabolic diseases.

Psychodynamic Psychotherapy for Children as a Trauma-Informed Intervention.

This article outlines the underpinnings of a psychodynamic approach for the treatment of childhood trauma through strengthening the implicit emotion regulation system. Childhood trauma impairs the functioning of the emotion regulation system, where deficits are common in children with post-traumatic stress disorder (PTSD). Difficulties with emotion regulation arise out of disruptions in the development of neurobiological pathways through the interaction of constitutional determinants with environmental factors, including the child's relationships with caregivers and the broader environment. We propose that a therapeutic focus on traumatized children's defenses can overcome the damaging reverberations of trauma. This approach may bypass the difficulties of high attrition rates, expense, and limited generalizability characteristic of skills training-based modalities. An illustration of an intervention to help children address unbearable emotions in traumatic experiences through defense interpretation is presented. The manualization and study of this approach within a project titled Regulation Focused Psychotherapy for Children (RFP-C) presents a unique opportunity to contribute to the evidence-based canon of treatments for children with histories of trauma.

Physician sentiment toward artificial intelligence (AI) in colonoscopic practice: a survey of US gastroenterologists.

Background and study aims Early studies have shown that artificial intelligence (AI) has the potential to augment the performance of gastroenterologists during endoscopy. Our aim was to determine how gastroenterologists view the potential role of AI in gastrointestinal endoscopy. Methods In this cross-sectional study, an online survey was sent to US gastroenterologists. The survey included questions about physician level of training, experience, and practice characteristics and physician perception of AI. Descriptive statistics were used to summarize sentiment about AI. Univariate and multivariate analyses were used to assess whether background information about physicians correlated to their sentiment. Results Surveys were emailed to 330 gastroenterologists nationwide. Between December 2018 and January 2019, 124 physicians (38 %) completed the survey. Eighty-six percent of physicians reported interest in AI-assisted colonoscopy; 84.7 % agreed that computer-assisted polyp detection (CADe) would improve their endoscopic performance. Of the respondents, 57.2 % felt comfortable using computer-aided diagnosis (CADx) to support a "diagnose and leave" strategy for hyperplastic polyps. Multivariate analysis showed that post-fellowship experience of fewer than 15 years was the most important factor in determining whether physicians were likely to believe that CADe would lead to more removed polyps (odds ratio = 5.09; P  = .01). The most common concerns about implementation of AI were cost (75.2 %), operator dependence (62.8 %), and increased procedural time (60.3 %). Conclusions Gastroenterologists have strong interest in the application of AI to colonoscopy, particularly with regard to CADe for polyp detection. The primary concerns were its cost, potential to increase procedural time, and potential to develop operator dependence. Future developments in AI should prioritize mitigation of these concerns.
