Bilateral rTMS Shows No Advantage in Depression nor in Comorbid Depression and Anxiety: A Naturalistic Study.

The objective was to determine if adding low-frequency right-sided rTMS treatment to the standard high-frequency left-sided treatment (LUL), referred to as sequential bilateral treatment (SBT), confers additional benefit for depression or anxiety outcomes. A retrospective chart review from January 2015 through December 2018 yielded 275 patients, all of whom were treated with a figure-8 coil for a major depressive episode. Their protocol was either LUL or SBL. Outcome measures were the Generalized Anxiety Disorder 7-item scale (GAD-7) and the Patient Health Questionnaire (PHQ-9). There was no significant difference in GAD-7 change scores between patients who had LUL or SBL (4.2 vs 4.8). This was also true when the sample was restricted to only patients who started with high GAD-7 scores. There was likewise no significant difference in PHQ-9 change scores between patients who had LUL or SBL (6.8 vs 5.1). Patients switching from LUL to SBL mid-course had poorer overall outcomes as compared to patients who stayed with the same protocol throughout treatment. This large naturalistic study shows no advantage for SBL treatment any group or condition examined. The results of this study have clinical applicability and sound a cautionary note regarding the use of combination rTMS protocols.

A water-soluble alternative to simethicone for gastrointestinal endoscopy: Results of a clinical trial.

During endoscopy, simethicone defoaming agents are commonly used to improve visualization, but they leave residues and impact drying. This clinical trial involved patients undergoing colonoscopy procedures with substantial bubbles that impeded mucosal wall visibility. As an alternative to simethicone, investigators evaluated a water-soluble, ginger-based gastrointestinal supplement (GI-Ease) that did not contain sugars, thickeners, or binding agents. In 112/114 cases (98%), the bubbles were reduced sufficiently to allow visualization of the gastrointestinal tract, with no adverse events.

Creating a Comprehensive Pandemic Response to Decrease Hospitalist Burnout During COVID-19: Intervention vs Control Results in 2 Comparable Hospitals (HOSP-CPR).

BACKGROUND: Physician burnout increased during the COVID-19 pandemic. OBJECTIVE: To evaluate the effectiveness of a multimodal workplace intervention designed to reduce hospitalist burnout. DESIGN: Participants and setting: Our intervention group was composed of internal medicine hospitalists at Providence Portland Medical Center (64 providers including 58 physicians and 6 nurse practitioners). Our control was composed of internal medicine hospitalists at Providence St Vincent's Hospital (59 physicians and 6 nurse practitioners). MEASUREMENTS: Two surveys were given during, before, and after a 12-month intervention period (October 2020 and again in October 2021). Surveys included demographics, job satisfaction, the Maslach Burnout Inventory, the Pandemic Experiences Survey, and 2 questions about leaving the job. INTERVENTIONS: Three hospitalists designated as wellness warriors created weekly COVID group meetings, providing up-to-date information about COVID-19 infection rates, treatments, and work-flow changes. Discussions included coping and vaccine hesitancy, difficult case debriefs, and intensive care unit updates. Individual coaching was also offered. Meeting minutes were taken and sessions were recorded for asynchronous access. RESULTS: No site differences in burnout or job satisfaction were evident pre-intervention. Post-intervention, the intervention group reported 32% burnout while controls reported 56% (p = .024). Forty-eight percent of the intervention group reported high wellness support vs. 0% of the controls (< .001). Intervention participants attributed 44% of wellness support to Providence alone, vs. controls at 12% (< .001). Regressions controlling sex, work hours, experience, race, and children in the home showed the intervention's positive effects on burnout and job satisfaction remained significant (all p < .02). LIMITATIONS: For privacy reasons, all survey responses were anonymous, meaning that individual pre-post changes could not be tracked. CONCLUSION: We believe the intervention resulted in substantial burnout prevention and is feasible for adoption in most hospitals and clinics.

Comparison of robotic versus laparoscopic right colectomy node retrieval in the obese population.

Data are scarce comparing robotic and laparoscopic colectomy node retrieval based on body mass index or age. With differences in anastomosis, mobilization, and ligation between these approaches, obese and/or elderly patients undergoing robotic surgery may have differences in node yield compared to laparoscopy. A retrospective review was conducted between four institutions from February 1, 2019 through August 1, 2021, during which 144 right colectomies were performed. Benign pathology, open colectomies, and conversions to open were excluded. All included surgeons had at least five patients to ensure experience. The population was categorized by a robotic or laparoscopic approach. Records were reviewed focusing on age, body mass index, surgical approach, anastomosis, pathology, and node count. The node count was then compared by body mass index and age between the robotic or laparoscopic approach to identify differences. After applied exclusions and outlier analysis, our final sample consisted of 80 patients. Both body mass index and age were significant, (p = 0.002 and p = 0.005, respectively). Body mass index ≤ 25.0 and age < 60 years old had higher average node counts. These variables interacted, (p = 0.003); those with both < 60 years old and body mass index ≤ 25 showed the greatest number of nodes (36.9). Laparoscopy yielded more nodes in ≥ 60 years old than robotics (27.4 verses 20.9), though this was not significant (p = 0.68). Node retrieval in overweight and obese patients did not differ between approaches (p = 0.48). Both body mass index and age influence the number of nodes that can be extracted in right hemicolectomies by experienced surgeons.

Impact of a multidisciplinary sepsis huddle in the emergency department.

BACKGROUND: Sepsis is a leading cause of death in hospitals requiring prompt recognition and treatment. The sepsis bundle is the cornerstone of sepsis treatment. Studies have evaluated the impact of a sepsis huddle on sepsis bundle compliance but not in sepsis identification. OBJECTIVE: Measure the effect of a multidisciplinary sepsis bedside huddle in the Emergency Department (ED) on sepsis identification and sepsis bundle compliance. METHODS: Retrospective, single-center, cohort study. Pre-huddle patients were identified via Best Practice Advisory (BPA) alert on the electronic medical record from 11/01/2019-3/31/2020. The post-huddle group were patients for whom a sepsis huddle was activated from 11/01/2020-3/31/2021. RESULTS: 116 patients met inclusion criteria and 15 were determined to not have sepsis for a total of 21 pre-huddle and 80 post-huddle patients. Comparing pre-post results, sepsis huddle increased code sepsis activation (10% vs 91%, p < 0.001); sepsis bundle compliance (24% vs 80%, p < 0.001); antibiotics within one hour (33% vs 90%, p < 0.001); culture within one hour (67% vs 95%, p < 0.001), order entry <30 min. (29% vs 86%, p < 0.001); and median order entry time (48 vs. 3 min, p < 0.001). Post-huddle, 80% of order entries were ≤ 20 min. Logistic regression predicting sepsis code found huddle to be the first predictor, (p < 0.0000005). Hour-1 bundle compliance was predicted by physician/physician assistant order ≤30 min (R2 = 0.36, p < 0.0000005). CONCLUSION: Sepsis bedside huddle in the ED improves identification and sepsis bundle compliance. Results suggest increased order entry speed caused bundle improvement.

Who was at risk for COVID-19 late in the US pandemic? Insights from a population health machine learning model.

Notable discrepancies in vulnerability to COVID-19 infection have been identified between specific population groups and regions in the USA. The purpose of this study was to estimate the likelihood of COVID-19 infection using a machine-learning algorithm that can be updated continuously based on health care data. Patient records were extracted for all COVID-19 nasal swab PCR tests performed within the Providence St. Joseph Health system from February to October of 2020. A total of 316,599 participants were included in this study, and approximately 7.7% (n = 24,358) tested positive for COVID-19. A gradient boosting model, LightGBM (LGBM), predicted risk of initial infection with an area under the receiver operating characteristic curve of 0.819. Factors that predicted infection were cough, fever, being a member of the Hispanic or Latino community, being Spanish speaking, having a history of diabetes or dementia, and living in a neighborhood with housing insecurity. A model trained on sociodemographic, environmental, and medical history data performed well in predicting risk of a positive COVID-19 test. This model could be used to tailor education, public health policy, and resources for communities that are at the greatest risk of infection.

Could bipolar depressed patients respond better to rTMS than unipolar depressed patients? A naturalistic, observational study.

Previous studies of rTMS for bipolar depressed (BD) patients have yielded mixed results. In this retrospective, naturalistic, observational study, we reviewed charts of 317 patients undergoing rTMS treatment between 1/2015-2/2018, yielding 283 unipolar depressed (UD) and 34 BD patients. All were treated with a figure-of-8 coil, with either high-frequency (HF) left-sided, sequential bilateral (HF left-sided and low-frequency right-sided), or mixed protocols (switched from unilateral to bilateral mid-course).  Outcomes were the Generalized Anxiety Disorder scale (GAD-7) and Patient Health Questionnaire (PHQ-9). Total number of treatments and initial PHQ-9 scores did not differ between groups. BD patients had greater PHQ-9 change by treatment conclusion than UD patients. GAD-7 changes showed no between-group differences overall. PHQ-9 changes differences between groups were only seen with unilateral treatment, not with bilateral or mixed protocols. Unilateral treatment resulted in 45% remission (9/20) for BD patients vs. 15% (24/160) for UD patients by treatment end. Response was seen in 80% (16/20) of the unilaterally-treated BD patients vs. 39% (62/160) in UD patients. Regression analyses within BD patients found that unilateral treatment, use of non-lithium mood stabilizers, male sex, and number of treatments predicted PHQ-9 improvement.

PCM1-JAK2 Fusion Tyrosine Kinase Gene-Related Neoplasia: A Systematic Review of the Clinical Literature.

BACKGROUND: This review summarizes the case studies of PCM1-JAK2 fusion tyrosine kinase gene-related neoplasia. Recommended treatment includes JAK2 inhibitors and hematologic stem cell transplantation (HSCT), although the small number of patients has limited study of their efficacy. Herein, we present all available cases in the current searchable literature with their demographics, diagnoses, treatments, and outcomes. METHODS: PubMed, ScienceDirect, Publons, the Cochrane Library, and Google were searched with the following terms: PCM1-JAK2, ruxolitinib and myeloid/lymphoid. RESULTS: Sixty-six patients (mean age = 50, 77% male) had an initial diagnosis of myeloproliferative neoplasm (MPN) in 40, acute leukemia in 21 and T-cell cutaneous lymphoma in 5. Thirty-five patients (53%) had completed 5-year follow-up. The 5-year survival for the MPN, acute myelogenous leukemia (AML), acute lymphocytic leukemia, and lymphoma groups are 62.7, 14.9%, 40.0%, and 100%, respectively. Too few patients have been treated with ruxolitinib to draw conclusions regarding its effect on survival while the 5-year survival for MPN patients with or without HSCT was 80.2% (40.3%-94.8%) versus 51.5% (22.3%-74.6%), respectively. The T-cell cutaneous lymphoma patients have all survived at least 7 years. CONCLUSION: This rare condition may be increasingly detected with wider use of genomics. Ruxolitinib can yield hematologic and molecular remissions. However, HSCT is, at this time, the only potentially curative treatment. Useful prognostic markers are needed to determine appropriate timing for HSCT in patients with MPN. Patients presenting with acute leukemia have a poor prognosis.

Eye-controlled, power wheelchair performs well for ALS patients.

BACKGROUND: Our pilot study tested the feasibility and performance of an eye-controlled power wheelchair for amyotrophic lateral sclerosis (ALS) patients. METHODS: In this prospective pilot study, participants drove the wheelchair three times around an indoor course. We assessed the time to complete the course; starting and stopping on command; turning 90, 135, and 180 degrees; time to backup; and obstacle negotiation. Following their use of the wheelchair, subjects were given a questionnaire to assess user experience. RESULTS: Twelve patients participated, and all were able to complete three trials without difficulty. Eight participants completed all of the individual tasks (eg, turning, stopping, etc.) without any errors. Overall performance ratings were high across all participants (4.6/5-excellent). CONCLUSIONS: Our eye-controlled power wheelchair prototype is feasible and has a very favorable user experience. This system has the potential to improve the mobility and independence of ALS patients, and other groups with motor impairments.

Predictors of Art and PrEP Adherence and Medication-Taking Practices and Preferences to Inform Development of a Wrist-Worn Adherence System.

We examined adherence, medication-taking practices, and preferences to inform development of a wrist-worn adherence system. Two convenience samples of persons taking antiretroviral therapy and HIV pre-exposure prophylaxis completed a survey. Additional online questions asked about willingness to use a wrist-worn device and reminder and feedback preferences. Among 225 participants, 13% reported adherence < 90%; this was associated with younger age and clinic sample. Compared to pill bottle-using participants, mediset users less commonly reported adherence < 90% (aOR = 0.16, p = .02), and blister pack users (aOR = 6.3, p = .02) and pill roll users (aOR = 3.3, p = .04) more commonly reported adherence < 90%. Sixty-two percent of the online participants reporting adherence (< 100%) had some interest in receiving adherence reminders, including 42% with interest in receiving reminders by smartwatch notifications. Although confounders are likely, formative work identified potential users and interest in using a wrist-worn adherence system. Future work will determine its acceptability and efficacy.

Does Maternal Buprenorphine Dose Affect Severity or Incidence of Neonatal Abstinence Syndrome?

OBJECTIVES: To measure the incidence, onset, duration, and severity of neonatal abstinence syndrome (NAS) in infants born to mothers receiving buprenorphine and to assess the association between buprenorphine dose and NAS outcomes. METHODS: We reviewed charts of all mother-infant pairs maintained on buprenorphine who delivered in our hospital from January 1, 2000 to April 1, 2016. RESULTS: In 89 infants, NAS incidence requiring morphine was 43.8%. Means for morphine-treated infants included: 55.2 hours to morphine start, 15.9 days on morphine, and 20 days hospital stay. NAS requiring morphine treatment occurred in 48.5% and 41.4% of infants of mothers receiving ≤8 mg/d buprenorphine versus >8 mg/d, respectively (P = 0.39). We found no significant associations of maternal buprenorphine dose with peak NAS score, NAS severity requiring morphine, time to morphine start, peak morphine dose, or days on morphine. Among the other factors examined, only exclusive breastfeeding was significantly associated with neonatal outcomes, specifically lower odds of morphine treatment (odds ratio 0.24, P = 0.003). CONCLUSIONS: These findings suggest higher buprenorphine doses can be prescribed to pregnant women receiving medication therapy for addiction without increasing NAS severity. Our finding of reduced risk of NAS requiring morphine treatment also suggests breastfeeding is both safe and beneficial for these infants and should be encouraged.

Dementia Services Mini-Screen: a simple method to identify patients and caregivers in need of enhanced dementia care services.

OBJECTIVE: Improving dementia care in health systems requires estimates of need in the population served. We explored whether dementia-specific service needs and gaps for patients and caregivers could be predicted by simple information readily captured in routine care settings. METHOD: Primary family caregivers (n = 215) rated their own current stress, challenging patient behaviors, and prior-year needs and gaps in 16 medical and psychosocial services. These were evaluated with other patient and caregiver characteristics in multivariate regressions to identify unique predictors of service needs and gaps. RESULTS: Caregiver stress and patient behavior problems together accounted for an average of 24% of the whole-sample variance in total needs and gaps. All other variables combined (comorbid chronic disease, dementia severity, age, caregiver relationship, and residence) accounted for a mean of 3%, with none yielding more than 4% in any equation. We combined stress and behavior problem indicators into a simple screen. In early/mild dementia dyads (n = 111) typical in primary care settings, the screen identified gaps in total (84%) and psychosocial (77%) care services for high stress/high behavior problem dyads vs. 25% and 23%, respectively, of low stress/low behavior problem dyads. Medical care gaps were dramatically higher in high stress/high behavior problem dyads (66%) than all others (12%). CONCLUSION: The Dementia Services Mini-Screen is a simple tool that could help clinicians and health systems rapidly identify dyads needing enhanced dementia care, track key patient and caregiver outcomes of interventions, and estimate population needs for new service development.

Comorbidity in aging and dementia: scales differ, and the difference matters.

BACKGROUND: Accurate assessment of the effect of dementia on healthcare utilization and costs requires separation of the effects of comorbid conditions, often poorly accounted for in existing claims-based studies. OBJECTIVE: To determine whether two different types of comorbidity and risk adjustment scales, the Chronic Disease Score (CDS) and the Cumulative Illness Rating Scale for Geriatrics (CIRS-G), perform similarly in older persons with and without dementia. METHODS: All subjects in the community-outreach diagnostic program of the University of Washington Alzheimer's Disease Research Center Satellite were included (N = 619). Subjects' mean age was 75 ± 9 years; 40% were cognitively normal, 17% were cognitively impaired but not demented, and 43% were demented. CDS and CIRS-G scores (neuropsychiatric disorders excluded to reduce colinearity with group) were examined across strata of age, education, and cognitive classification by using analysis of variance, analysis of covariance, and linear regression. RESULTS: CIRS-G scores were sensitive to factors known to be associated with chronic disease burden, including age (F = 21.3 [df = 2, 616], p <0.001), education (F = 6.6 [df = 3, 614], p <0.001), and cognitive status (F = 40.5 [df = 2, 616], p <0.001), whereas the CDS was not. In the subset of persons with CDS scores of 0 (40% of the total sample), CIRS-G scores ranged from very low to high burden of disease and remained significantly different across age, education, and cognitive status groups. In regression analyses predicting CIRS-G score, CDS score and cognitive status interacted (ß = -0.10, t = 1.9 [df = 1, 609], p = 0.06). After controlling for age, the amount of variance shared by the CIRS-G-13 and CDS differed by cognitive group (>32% for normal and mildly impaired groups combined, 17% for dementia). CONCLUSION: Different methods of measuring and adjusting for comorbidity are not equivalent, and dementia amplifies the discrepancies. The CDS, if used to control for comorbidity in comparative studies of healthcare utilization and costs for persons with and without dementia, will underestimate burden of comorbid disease and artificially inflate the costs attributed to dementia.

Screening for undiagnosed cognitive impairment in homebound older adults.

OBJECTIVE: To screen for undetected cognitive impairment in homebound elders receiving home health care services. DESIGN: A cross-sectional study of adults 60 years of age and older receiving visiting nurse services. A pharmacist administered the Mini-Cog, a rapid screening test for cognitive impairment, during the enrollment home visit. SETTING: Participants' homes. PARTICIPANTS: A consecutive sample of 100 homebound adults, 60 years of age or older with no previous diagnosis of dementia, Alzheimer's disease, or other cognitive impairment. MAIN OUTCOME MEASURE: Percentage of participants scoring in the likely impaired range (screen failure) on the Mini-Cog. RESULTS: Seventeen percent of persons with no prior diagnosis of dementia or cognitive decline failed the Mini-Cog. CONCLUSION: Rates of undetected cognitive impairment are substantial in homebound elders receiving care from a visiting nurse service. The home health setting represents an important point in the continuum of geriatric care for detection of cognitive impairment. Future work should define the types and trajectories of cognitive impairment detected in home care patients by simple screens such as the Mini-Cog and test ways to integrate this knowledge into longitudinal treatment plans across settings of care.

Depressed mood mediates decline in cognitive processing speed in caregivers.

PURPOSE: Very few studies have examined cognitive decline in caregivers versus noncaregivers, and only 1 study has examined mediators of such decline. We evaluated the relationship between caregiver status and decline on the digit symbol test (DST; a measure of processing speed, attention, cognitive-motor translation, and visual scanning) and whether this relationship was mediated by depressed mood. DESIGN AND METHODS: Caregivers for spouses with Alzheimer's disease (n = 122) were compared with demographically similar noncaregiver spouses (n = 117) at study entry (Time 1 = T1), T2 (1 year later), and T3 (2 years after T1). RESULTS: Caregivers had lower DST scores and higher Hamilton depression scores at T1, T2, and T3 than noncaregivers (all p < .05). Hierarchical linear modeling revealed that although caregivers started well below noncaregivers, they experienced a more rapid rate of decline than noncaregivers (p = .047). Caregivers declined 4.5 times faster than noncaregivers. Greater depressed mood at T1 (p < .01) and T2 (p < .01) predicted DST decline and mediated DST decline in caregivers vs. noncaregivers. IMPLICATIONS: Depressed mood in caregivers relative to noncaregivers may influence their greater risk for DST decline. This is important because the DST predicts problem solving and everyday functions necessary for independent living and the potential well-being of their care recipients.

Time that tells: critical clock-drawing errors for dementia screening.

BACKGROUND: Clock-drawing tests are popular components of dementia screens but no single scoring system has been universally accepted. We sought to identify an optimal subset of clock errors for dementia screening and compare them with three other systems representative of the existing wide variations in approach (Shulman, Mendez, Wolf-Klein), as well as with the CDT system used in the Mini-Cog, which combines clock drawing with delayed recall. METHODS: The clock drawings of an ethnolinguistically and educationally diverse sample (N = 536) were analyzed for the association of 24 different errors with the presence and severity of dementia defined by independent research criteria. The final sample included 364 subjects with > or = 5 years of education, as preliminary examination suggested different error patterns in subjects with 0-4 years of education and inadequate numbers of normal controls for reliable analysis. RESULTS: Eleven of 24 errors were significantly associated with dementia in subjects with > or = 5 years of education, and six were combined to identify dementia with 88% specificity and 71% sensitivity: inaccurate time setting, no hands, missing numbers, number substitutions or repetitions, or refusal to attempt clock drawing. Time setting was the most prevalent error at all dementia stages, refusal occurred only in moderate and severe dementia; and ethnicity and language of administration had no effect. All critical errors increased in frequency with dementia stage. This simplified scoring system had much better specificity than two other systems (88% vs 39% for Mendez's system - 63% for Shulman's) and much better sensitivity than Wolf-Klein's (71% vs 51%). Stepwise logistic regression found the simplified system to be more strongly predictive of dementia than the three other CDT systems of dementia. Substituting the new CDT algorithm for that used in the original CDT Mini-Cog improved the Mini-Cog's specificity from 89 to 93% with minimal change in sensitivity. CONCLUSIONS: Only six errors need be assessed to capture most of the power of clock drawing to discriminate between people with dementia and normal subjects, and improves specificity over older systems in subjects with > or = 5 years of education. These errors require minimal conceptual classification and are easily detected and scored by non-specialists.

Cognitive impairment, chronic disease burden, and functional disability: a population study of older Italians.

OBJECTIVE: To evaluate associations of cognitive impairment and disease burden with disability in an elderly population. METHODS: The Mini-Cog was used as a cognitive screen in a population-based survey of health and functional status of 2,192 randomly selected older adults (age 65+ years) in 11 regions of Italy. Associations of cognitive and disease measures with functional outcomes were calculated using hierarchical logistic regressions including age, Mini-Cog score, disease burden, age, education, and geographic region. Statistical significance was assigned at p <0.01. RESULTS: Mini-Cog scores were related to all functional indicators (activities of daily living [ADLs], social activities, exercise, telephone and face-to-face conversation, urinary control, and ability to read the newspaper) as well as stroke, falls, and dementia diagnoses. In univariate analyses, low education was associated with Mini-Cog scores, disease burden, and disability. However, in logistic regressions, Mini-Cog score and disease burden, but not education, remained significant predictors of all basic ADLs and most higher-order functions. Functional disability was best predicted by a Mini-Cog cutoff score of 1 out of 5. Overall, although both are significant, the impact of cognitive impairment on basic ADL impairment was over four times greater than that of disease burden (accounting for 14% versus 3% of variance). CONCLUSION: Cognitive impairment assessed by the Mini-Cog is a more powerful predictor of impaired ADLs than disease burden in older adults. The association of education with Mini-Cog score did not bias its ability to predict functional status. Results suggest that the Mini-Cog could be useful in assessing older population assistance needs.

The Mini-Cog: a rapid dementia screening tool suitable for pharmacists' use.

OBJECTIVE: To familiarize the consultant pharmacist with the use of the Mini-Cog as a rapid screening tool for the assessment of dementia and outline currently available evidence regarding the validity of this screening tool within the community. DATA SOURCES: MEDLINE (1990-December 2006) and Web of Science (1995-December 2006) were searched for original research and review articles published in English. STUDY SELECTION AND DATA EXTRACTION: Relevant literature regarding use of the Mini-Cog. DATA SYNTHESIS: There exists a growing literature base regarding the clinical use of the Mini-Cog. Dementia within the elderly ambulatory population remains largely unrecognized. A rapid screening tool such as the Mini-Cog is a valuable instrument for health care practitioners, including consultant pharmacists, within the community to identify patients with possible cognitive impairment. CONCLUSION: The Mini-Cog provides pharmacists with an easy and effective tool for the screening of dementia within assisted living, long-term care, and community-dwelling populations.
