RESUMO

INTRODUCTION: Family, friends, and romantic partners (i.e., supporters) play a key role in the implementation of safety and support measures for loved ones with elevated risk for suicide; yet despite the link between interpersonal factors and suicide risk, few supporter-focused interventions exist. METHOD: This qualitative study to inform intervention development was conducted from September 2021 to March 2022 and explored (a) the feasibility and acceptability of a single-session phone call to a support person (n = 30, 67% female, 88% White non-Hispanic, Mage = 40.3 [SD = 17.1]) nominated during an emergency department (ED) visit for suicide risk and (b) the needs of supporters during and after a loved one's suicide crisis. RESULTS: Of the 30 supporters nominated, 27 were eligible to participate and were contacted. Eighteen completed an interview (66%). Seven core themes with 26 subthemes were identified characterizing the supporter's experience prior to, during, and following their loved one's suicide crisis. We found moderate acceptability and feasibility of a single-session supportive phone call to a support person following an ED visit for suicide risk. DISCUSSION: Supporters reported a period of stress prior to and during the ED visit as well as adaptive coping with continued barriers and challenges. Brief interventions aimed at improving communication between the supporter, patient, and their care team; defining roles; and enhancing practical and emotional support are likely to be acceptable and feasible. Further study is needed to determine whether brief interventions to improve supporter self-efficacy can benefit both supporter and patient.

RESUMO

OBJECTIVE: To explore the social determinants of mental health (SDoMH) by race/ethnicity in a sample with equal access to healthcare. Using an adaptation of the World Health Organization's SDoMH Framework, this secondary analysis examines the socio-economic factors that make up the SDoMH by race/ethnicity. METHOD: This paper employed configurational comparative methods (CCMs) to analyze various racial/ethnic subsets from quantitative survey data from (N = 327) active-duty Army wives. Data was collected in 2012 by Walter Reed Army Institute of Research. RESULTS: Initial exploratory analysis revealed the highest-scoring factors for each racial/ethnic subgroup: non-Hispanic Black: employment and a history of adverse childhood events (ACEs); Hispanic: living off post and a recent childbirth; junior enlisted non-Hispanic White: high work-family conflict and ACEs; non-Hispanic other race: high work-family conflict and not having a military history. Final analysis showed four models consistently explained clinically significant depression symptoms and four models consistently explained the absence of clinical depression symptoms, providing a solution for each racial/ethnic minority group (non-Hispanic Black, Hispanic, junior enlisted non-Hispanic White, and non-Hispanic other). DISCUSSION: These findings highlight that Army wives are not a monolithic group, despite their collective exposure to military-specific stressors. These findings also highlight the potential for applying configurational approaches to gain new insights into mental health outcomes for social science and clinical researchers.

RESUMO

Importance: Despite the availability of several empirically supported trauma-focused interventions, retention in posttraumatic stress disorder (PTSD) psychotherapy is poor. Preliminary efficacy data shows that brief, family-based interventions may improve treatment retention in a veteran's individual PTSD treatment, although whether this occurs in routine clinical practice is not established. Objective: To characterize receipt of family therapy among veterans diagnosed with PTSD and evaluate whether participation in family therapy is associated with an increased likelihood of completing individual trauma-focused treatment. Design, Setting, and Participants: This retrospective cohort study used the Veterans Health Administration (VHA) Informatics and Computing Infrastructure to extract electronic health record data of participants. All participants were US veterans diagnosed with PTSD between October 1, 2015, and December 31, 2019, who attended at least 1 individual trauma-focused treatment session. Statistical analysis was performed from May to August 2023. Exposures: Receipt of any family psychotherapy and subtype of family-based psychotherapy. Main Outcomes and Measures: Minimally adequate individual trauma-focused treatment completion (ie, 8 or more sessions of trauma-focused treatment in a 6-month period). Results: Among a total of 1 516 887 US veterans with VHA patient data included in the study, 58 653 (3.9%) received any family therapy; 334 645 (23.5%) were Black, 1 006 168 (70.5%) were White, and 86 176 (6.0%) were other race; 1 322 592 (87.2%) were male; 1 201 902 (79.9%) lived in urban areas; and the mean (SD) age at first individual psychotherapy appointment was 52.7 (15.9) years. Among the 58 653 veterans (3.9%) who received any family therapy, 36 913 (62.9%) received undefined family therapy only, 15 528 (26.5%) received trauma-informed cognitive-behavioral conjoint therapy (CBCT) only, 5210 (8.9%) received integrative behavioral couples therapy (IBCT) only, and 282 (0.5%) received behavioral family therapy (BFT) only. Compared with receiving no family therapy, the odds of completing individual PTSD treatment were 7% higher for veterans who also received CBCT (OR, 1.07 [95% CI, 1.01-1.13]) and 68% higher for veterans received undefined family therapy (OR, 1.68 [95% CI, 1.63-1.74]). However, compared with receiving no family therapy care, veterans had 26% lower odds of completing individual PTSD treatment if they were also receiving IBCT (OR, 0.74 [95% CI, 0.66-0.82]). Conclusions and Relevance: In this cohort study of US veterans, family-based psychotherapies were found to differ substantially in their associations with individual PTSD psychotherapy retention. These findings highlight potential benefits of concurrently providing family-based therapy with individual PTSD treatment but also the need for careful clinical attention to the balance between family-based therapies and individual PTSD treatment.

RESUMO

BACKGROUND/OBJECTIVE: The Veterans Health Administration (VHA) has prioritized timely access to care and has invested substantially in research aimed at optimizing veteran access. However, implementing research into practice remains challenging. Here, we assessed the implementation status of recent VHA access-related research projects and explored factors associated with successful implementation. DESIGN: We conducted a portfolio review of recent VHA-funded or supported projects (1/2015-7/2020) focused on healthcare access ("Access Portfolio"). We then identified projects with implementable research deliverables by excluding those that (1) were non-research/operational projects; (2) were only recently completed (i.e., completed on or after 1/1/2020, meaning that they were unlikely to have had time to be implemented); and (3) did not propose an implementable deliverable. An electronic survey assessed each project's implementation status and elicited barriers/facilitators to implementing deliverables. Results were analyzed using novel Coincidence Analysis (CNA) methods. PARTICIPANTS/KEY RESULTS: Among 286 Access Portfolio projects, 36 projects led by 32 investigators across 20 VHA facilities were included. Twenty-nine respondents completed the survey for 32 projects (response rate = 88.9%). Twenty-eight percent of projects reported fully implementing project deliverables, 34% reported partially implementing deliverables, and 37% reported not implementing any deliverables (i.e., resulting tool/intervention not implemented into practice). Of 14 possible barriers/facilitators assessed in the survey, two were identified through CNA as "difference-makers" to partial or full implementation of project deliverables: (1) engagement with national VHA operational leadership; (2) support and commitment from local site operational leadership. CONCLUSIONS: These findings empirically highlight the importance of operational leadership engagement for successful implementation of research deliverables. Efforts to strengthen communication and engagement between the research community and VHA local/national operational leaders should be expanded to ensure VHA's investment in research leads to meaningful improvements in veterans' care. The Veterans Health Administration (VHA) has prioritized timely access to care and has invested substantially in research aimed at optimizing veteran access. However, implementing research findings into clinical practice remains challenging, both within and outside VHA. Here, we assessed the implementation status of recent VHA access-related research projects and explored factors associated with successful implementation. Only two factors were identified as "difference-makers" to adoption of project findings into practice: (1) engagement with national VHA leadership or (2) support and commitment from local site leadership. These findings highlight the importance of leadership engagement for successful implementation of research findings. Efforts to strengthen communication and engagement between the research community and VHA local/national leaders should be expanded to ensure VHA's investment in research leads to meaningful improvements in veterans' care.

RESUMO

OBJECTIVES: We investigate the number of autopsy reports that did or did not document the presence or absence of the gallbladder or appendix or document abdominal scars in patients following cholecystectomy or appendectomy. We also report gallbladder and appendix pathology at autopsy. METHODS: Autopsy reports from patients 18 years or older autopsied at a community teaching hospital between January 1, 2009, and December 31, 2018 were reviewed. Nonabdominal autopsies were excluded. Histopathologic examination of the gallbladder and appendix was only performed if gross pathology was seen. RESULTS: Of the 385 autopsies studied, 48 (12.5%) had cholecystectomies, of which 6 (12.5%) did not document abdominal scars. Sixty-two (16.1%) had appendectomies, of which 12 (19.4%) did not document abdominal scars. The presence or absence of the gallbladder and appendix was not documented in 6 (1.6%) and 16 (4.2%) of reports, respectively. Pathology was seen in 87 (25.8%) gallbladders and 4 (1.2%) appendixes. CONCLUSIONS: Absence of the gallbladder or appendix is a relatively common autopsy finding. Auditing autopsy reports for documentation of their presence or absence, along with associated abdominal scars, are potential quality assurance indicators of autopsy reports. Documentation of these elements could be improved by changing the autopsy template or using synoptic reporting.

RESUMO

AIMS: This short study was performed to better understand the time frame associated with changes in SARS-CoV-2 nucleic acid testing and provide recommendations for repeat testing. Recommendations are useful as little guidance is available for repeat testing in patients being followed expectantly for changes in disease. METHODS: A review of laboratory data of tests for SARS-CoV-2 nucleic acid was performed selecting patients who had changing results. Time between changes in test results was determined to provide guidance for repeat testing. RESULTS: The Interquartile Range (IQR) of data for patients who had a negative to positive change in laboratory testing (progression) was 6-16 days (median=9 days). The IQR of data for patients who had a positive to negative change in test results (remission) was 9-21 days (median=14 days). CONCLUSION: Because sampling of the nares or nasopharynx can be variable, repeat testing should be performed swiftly when symptomatic patients are negative. The data in this short study vary widely, so authors recommend repeat testing during a period of time associated with the IQR or median (see results above).

RESUMO

Cystic neutrophilic granulomatous mastitis (CNGM) is a distinct histopathologic entity characterized by neutrophilic and granulomatous inflammation surrounding clear cystic spaces. Rare gram-positive bacilli are sometimes identified within these cystic spaces. Studies in the literature have identified these gram-positive bacilli to be Corynebacterium species. We describe the clinicopathologic features of 7 cases of CNGM, including a case with evidence of Corynebacterium amycolatum. Patients were young to middle aged parous women ranging in age from 28 to 53 years (median age: 41 years). Gram-positive bacilli were identified in 4 cases, all within cystic spaces. Microbial culture from a 41-year old Hispanic woman grew Corynebacterium species on multiple occasions and Corynebacterium amycolatum was identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) on two separate occasions. Antibiotic susceptibility testing performed both times showed resistance to multiple antibiotics and susceptibility to vancomycin. Follow-up of all patients (range 3-12 months, median 6 months) showed a widely variable clinical course and varying response to a variety of treatment modalities. Five of the seven CNGM patients were parous, reproductive-aged Hispanic women who were born outside of the United States. Our findings further support the association of CNGM with corynebacteria and gram-positive bacilli. Furthermore, this study shows that Corynebacterium amycolatum, a nonlipophilic and multidrug-resistant corynebacterium can be associated with CNGM, hence the need for targeted antibiotic therapy. We propose identifying corynebacteria to the species level and performing antibiotic susceptibility testing in patients with CNGM because of the varied susceptibility testing profile that has been reported among different species of corynebacteria.

RESUMO

BACKGROUND: Kleefstra syndrome (KS) is a rare autosomal dominant developmental disability, caused by microdeletions or intragenic mutations within the epigenetic regulator gene EHMT1 (euchromatic histone lysine N-methyltransferase 1). In addition to common features of autism, young adult regressive behaviors have been reported. However, the genetic downstream effects of the reported deletions or mutations on KS phenotype have not yet been completely explored. While genetic backgrounds affecting drug metabolism can have a profound effect on therapeutic interventions, pharmacogenomic variations are seldom considered in directing psychotropic therapies. METHODS: In this report, we used next-generation sequencing (exome sequencing and high-throughput RNA sequencing) in a patient and his parents to identify causative genetic variants followed by pharmacogenomics-guided clinical decision-making for making positive changes toward his treatment strategies. The patient had an early autism diagnosis and showed significant regressive behaviors and physical aberrations at age 23. RESULTS: Exome sequencing identified a novel, de novo splice site variant NM_024757.4: c.2750-1G>T in EHMT1, a candidate gene for Kleefstra syndrome, in the patient that results in exon skipping and downstream frameshift and termination. Gene expression results from the patient showed, when compared to his parents, there was a significant decreased expression of several reported gene variants associated with autism risk. Further, using a pharmacogenomics genotyping panel, we discovered that the patient had the CYP2D6 nonfunctioning variant genotype *4/*4 that results in very low metabolic activity on a number of psychotropic drugs, including fluvoxamine which he was prescribed. As reported here, a change in psychotropic drugs and intense behavior therapies resulted in a significant reversal of the regressive behaviors and physical aberrations. CONCLUSION: These results demonstrate an individualized approach that integrated genetic information and behavior therapies, resulting in a dramatic improvement in regressive behaviors associated with KS.

RESUMO

Variation among existing studies in labeling, defining, identifying, and subtyping cases of suspected drug-facilitated sexual assault (DFSA) poses challenges to integrating research findings for public health purposes. This descriptive study addressed methodological issues of nomenclature and DFSA operational definitions to improve case identification and was designed to distinguish assault subtypes. We studied a 2-year ethnically diverse cohort of 390 patients who presented acutely to an urban rape treatment center (RTC). We abstracted data from RTC medical and mental health records via chart review. Assault incidence rates; engagement into medical, forensic, and mental health services; injury sustained; and weapon use were calculated separately for assault subtypes and compared. DFSA accounted for over half of the total sexual assault (SA) cases. Involuntary DFSA (in which an incapacitating substance was administered to victims without their knowledge or against their will) increased from 25% to 33% of cases over the 2-year period. DFSA victims presented sooner, and more often attended medical follow-up and psychotherapy than non-DFSA victims. Incidence rates indicated increasing risk for young males. These findings indicate that DFSA continues to be a growing and complex phenomenon and suggest that DFSA victims have greater service needs. The field would benefit from innovations to address symptomatology arising from this novel type of trauma and the unique risks and needs of male victims, as well as underscoring the ongoing need for DFSA-specific prevention efforts for both victims and perpetrators.

RESUMO

PURPOSE: To evaluate the utility of urine protein/creatinine ratio (uPCR) measurements among healthy parturients at term we performed a prospective cohort study at a community teaching hospital. METHODS: Serial urine samples were collected. Ninety-three women contributed 284 urine samples. uPCRs were determined. Multiple imputation and paired sampled analysis was performed when appropriate. RESULTS: Two-thirds (63/93) of women had at least one measured uPCR ≥ 0.3. One-third (31/93) had a uPCR ≥ 0.3 at admission, including 39.1% (9/23) of women not in labor. Median (IQR) uPCRs increased during labor and after delivery: latent phase/no labor, 0.15 (0.06-0.32); active phase, 0.29 (0.10-0.58); early postpartum, 0.45 (0.18-1.36) (all p < 0.04). Median uPCRs were significantly < 0.3 in the latent phase and significantly > 0.3 in the immediate postpartum period (p < 0.01). Women who labored before cesarean delivery had the highest early postpartum uPCRs: median (IQR) 1.16 (0.39-1.80). A negative urine dipstick protein result did not exclude uPCR ≥ 0.3. uPCRs were similar when compared by method of urine collection. CONCLUSION: uPCR ≥ 0.3 is common among healthy women with uncomplicated pregnancies at term. uPCR increases during labor and is not a reliable measure of pathologic proteinuria at term or during the peripartum period.

RESUMO

Primary gastric squamous cell carcinoma (PGSCC) is an exceedingly rare disease, accounting for 0.04% - 0.07% of all gastric cancers. First reported in 1895 by Rörig et al, less than 100 cases of PGSCC worldwide have been reported in the literature. These reports show PGSCC is more common in males (5:1 male to female ratio), and exhibits a peak incidence in the sixth decade of life. It may involve any portion of the stomach with predilection for the proximal stomach, especially along the lesser curvature. Although no clear pathogenesis of this tumor has been reported, several plausible theories have been proposed. These include squamous differentiation of preexisting gastric adenocarcinoma, cancerization of ectopic squamous epithelium, malignant transformation of squamous metaplasia of glandular epithelium, association with Helicobacter pylori or Epstein-Barr virus infection, and evolution in the setting of marked chronic gastritis with intestinal metaplasia. This report presents and discusses the case of a 64-year-old female who developed PGSCC arising in the gastric fundus.

RESUMO

A 52-year-old female presented with hematochezia. A computed topography (CT) scan revealed diffuse proximal gastric thickening with enlarged perigastric lymph nodes. The esophagogastroduodenoscopy (EGD) revealed a diffusely thickened gastric wall with hemorrhagic, friable mucosa, and multiple areas of ulceration. The biopsies showed diffuse amyloid deposition along with transmural proliferation of small- to medium-sized lymphocytes and plasma cells. The gastric mucosa showed lymphoepithelial lesions and chronic inactive gastritis. Immunohistochemical staining of the neoplastic lymphocytes revealed expression of CD20, bcl-2, bcl-10, Ki-67 proliferative index of 5%, and lambda light chain restriction. There was no expression of CD5, CD43, CD10, CD3, cyclin D1, and bcl-6. Immunophenotyping by flow cytometry revealed an abnormal B lymphocyte population with expression of CD45, CD19, CD20, and FMC7. The histomorphological, immunohistochemical and flow cytometric features were consistent with primary gastric amyloidosis associated with extranodal marginal zone lymphoma of mucosa associated lymphoid tissue (MALT lymphoma).

RESUMO

Although health professions worldwide are shifting to competency-based education, no common taxonomy for domains of competence and specific competencies currently exists. In this article, the authors describe their work to (1) identify domains of competence that could accommodate any health care profession and (2) extract a common set of competencies for physicians from existing health professions' competency frameworks that would be robust enough to provide a single, relevant infrastructure for curricular resources in the Association of American Medical Colleges' (AAMC's) MedEdPORTAL and Curriculum Inventory and Reports (CIR) sites. The authors used the Accreditation Council for Graduate Medical Education (ACGME)/American Board of Medical Specialties six domains of competence and 36 competencies delineated by the ACGME as their foundational reference list. They added two domains described by other groups after the original six domains were introduced: Interprofessional Collaboration (4 competencies) and Personal and Professional Development (8 competencies). They compared the expanded reference list (48 competencies within eight domains) with 153 competency lists from across the medical education continuum, physician specialties and subspecialties, countries, and health care professions. Comparison analysis led them to add 13 "new" competencies and to conflate 6 competencies into 3 to eliminate redundancy. The AAMC will use the resulting "Reference List of General Physician Competencies" (58 competencies in eight domains) to categorize resources for MedEdPORTAL and CIR. The authors hope that researchers and educators within medicine and other health professions will consider using this reference list when applicable to move toward a common taxonomy of competencies.

RESUMO

BACKGROUND: Pancreatic endocrine neoplasms (PENs) are a well-defined and well-characterized group of tumors. We report a rare variant of PENs called a lipid-rich variant and elaborate on its cytologic features with reference to fine needle aspiration (FNA). CASE: The patient was a 74-year-old man with a 2.1-cm mass in the body of the pancreas. The FNA showed numerous cells with vacuolated, foamy cytoplasm, mostly arranged individually but also in some apparently cohesive clusters. The nuclei were quite uniform. Many of the cells had the appearance of histiocytes. The cells in the cell block were immunoreactive (positive) for cytokeratin AE1/AE3, synaptophysin, and chromogranin A. Some admixed histiocytes stained for CD68. A diagnosis of PEN was made, with a suspicion for lipid-rich variant. An elective resection of the tumor was performed, which confirmed the diagnosis of lipid-rich variant of PENs. Lipid-rich variant of PENs can present a diagnostic dilemma on FNA. CONCLUSION: Its mimickers include adrenal cortical carcinoma, metastatic clear-cell renal cell carcinoma, clear-cell PEN, foamy gland pattern of pancreatic ductal carcinoma, solid pseudopapillary tumor, and acinar cell carcinoma. The distinguishing morphologic and immunohistochemical features of each are described.
