Ambulatory visits for common rhinologic complaints in the United States: A patient-centered perspective.

The National Ambulatory Medical Care Survey (NAMCS) is a collection of publicly available and deidentified patient data gathered from participating tertiary medical centers. With it, this study attempts to describe and quantify distribution of patients presenting with a rhinologic reason for visit (RFV) in the ambulatory setting, as well as determine the distribution based on specialty and setting of practice. Data from years 2014-2016 in the NAMCS were analyzed to determine the overall number of visits for a rhinologic RFV, the distribution according to RFV, the medical specialty of the clinical provider and patient demographics. 20.1 Million ambulatory visits with a rhinologic RFV, annualized, were identified. The dominant RFVs were nasal congestion (41.9%), sinus problems (14.5%), sinus pain/pressure (10.6%), hay fever (10.5%), sinus congestion (7.5%), sinus inflammation or infection (5.7%), and epistaxis (4.0%). The majority of the most common complaints were addressed by primary care physicians (64.5% of nasal congestion, 63.9% of sinus problems, and 75.7% of sinus pain/pressure), whereas epistaxis, disturbances of sense, and inflammation of the nose were more likely to be addressed by an otolaryngologist (58.9%, 28.8%, and 63.0%, respectively). Non-metropolitan areas generated more primary care visits (90.1%) than metropolitan areas (50.2%) (p < 0.001). The Northeast garnered the highest number of otolaryngology visits (32.4%) and lowest of primary care (59.1%). Patients with common rhinologic complaints present to primary care more frequently than to otolaryngology, though this pattern varies depending on the specific rhinologic RFV and depending on region and setting of practice.

403. Clinical Characteristics and Outcomes of Patients with COVID-19 Admitted to the Intensive Care Unit in the Dominican Republic

BackgroundThe disease caused by SARS-CoV-2, COVID-19, has caused a global public health crisis. Reported mortality rates across the world vary by region, local population characteristics and healthcare systems. There is a paucity of data on COVID-19 in low and middle income countries (LMICs). Our objective is to describe the clinical characteristics of critically ill patients with COVID-19 in the Dominican Republic (DR) MethodsWe performed a retrospective review of patients admitted to the intensive care unit (ICU) with severe COVID-19 from March to December 31, 2020, at a 295-bed tertiary teaching hospital in the DR. Clinical characteristics, demographics, comorbidities, management and outcomes were tabulated. Survival was categorized by age and comorbidities.ResultsA total of 382 patients were admitted to the ICU. The median age was 64 (range 14-97) and 64.3% (246) were male. Hypertension, diabetes, and obesity were the most common risk factors (Table 1). Corticosteroids were used in 91.6% (350), tocilizumab in 63% (82), and remdesivir in 31.6% (31). Antibacterials were used in 99.2% (379) of patients in the ICU. All-cause mortality in the ICU was 35.3% (135). Mortality was higher in older age groups (Figure 1) and in patients with multiple coexisting comorbidities (Figure 2). Table 1.

Mortality by age groupsFIgure 2. Mortality by cumulative number of comorbiditiesConclusionHypertension, obesity and diabetes were common in critically ill patients with COVID-19 in the DR. Corticosteroids and tocilizumab were commonly used. Antibacterials were used in >99% of patients admitted to the ICU and may signal a target for future antimicrobial stewardship. Higher mortality rates were present in older age groups and those with multiple comorbidities. Risk of death increased drastically after age 40 and was comparative to those in advanced age groups. In patients with 4 comorbidities and above, mortality was more than three times higher.Disclosures All Authors: No reported disclosures

ATN classification in dementia with Lewy bodies: Association with clinical profile, cognitive decline and survival

AbstractBackgroundThe ATN framework has been developed to characterize biological processes within the Alzheimer’s disease (AD) continuum. Since AD pathology often coincides with dementia with Lewy Bodies (DLB), we aimed to examine the distribution of ATN profiles in DLB and associate ATN‐profiles in DLB to prognosis.MethodWe included 192 DLB patients from the Amsterdam Dementia Cohort (68±7yrs, 19%F, MMSE: 24±3, DAT‐SPECT abnormal: 104/114). Patients were classified according to the ATN framework, using CSF Aβ1‐42 (A), CSF p‐tau (T) and medial temporal atrophy scores (N). Categories were compared on presence of clinical symptoms and demographics. To yield sufficient power for longitudinal analyses, the eight profiles were combined into four categories: normal AD biomarkers (A‐T‐N‐, reference), non‐AD pathologic change (A–T–N+/A–T+N–/A–T+N+), amyloid‐only (A+T‐N‐) and amyloid‐plus (A+T–N+/A+T+N–/A+T+N+). We used linear mixed models to analyze decline in MMSE (follow‐up 3±2yrs for n=137). We assessed differences in mortality using Cox proportional‐hazards models.ResultFifty (26%) DLB patients had normal AD biomarkers (A‐T‐N‐), 36 (19%) had non‐AD pathologic change (A‐T+N‐: 10%/A‐T‐N+: 6%/A‐T+N+: 3%) and 106 (55%) were classified within the AD‐continuum (A+T‐N‐: 20%/A+T+N‐: 16%/A+T‐N+: 10%/A+T+N+: 9%)(figure 1). A+T+N+ patients were older and less often had RBD symptoms. Compared to patients with normal AD biomarkers, those with amyloid‐only had steeper decline in MMSE (β±SE=‐0.82±0.28, p=0.005), while amyloid‐plus was associated to higher mortality rate (HR: 1.85[1.09‐3.13]). Cognitive decline and mortality did not differ between non‐AD pathologic change and normal AD biomarkers (figure 2‐3).ConclusionIn our DLB cohort, we found clinically relevant associations between ATN categories and disease manifestation. Patients within the AD‐continuum had steeper cognitive decline (especially amyloid‐only) and shorter survival (amyloid‐plus). Individuals with non‐AD pathologic change did not differ from those with normal AD biomarkers in clinical presentation, decline or survival. Implementing the ATN framework within DLB patients could aid in subtyping patients based on underlying biological processes and provide targets for future treatment strategies, e.g. AD modifying treatment.

Single-Examination Risk Prediction of Severe Retinopathy of Prematurity.

Retinopathy of prematurity (ROP) is a leading cause of childhood blindness. Screening and treatment reduces this risk, but requires multiple examinations of infants, most of whom will not develop severe disease. Previous work has suggested that artificial intelligence may be able to detect incident severe disease (treatment-requiring retinopathy of prematurity [TR-ROP]) before clinical diagnosis. We aimed to build a risk model that combined artificial intelligence with clinical demographics to reduce the number of examinations without missing cases of TR-ROP. Infants undergoing routine ROP screening examinations (1579 total eyes, 190 with TR-ROP) were recruited from 8 North American study centers. A vascular severity score (VSS) was derived from retinal fundus images obtained at 32 to 33 weeks' postmenstrual age. Seven ElasticNet logistic regression models were trained on all combinations of birth weight, gestational age, and VSS. The area under the precision-recall curve was used to identify the highest-performing model. The gestational age + VSS model had the highest performance (mean ± SD area under the precision-recall curve: 0.35 ± 0.11). On 2 different test data sets (n = 444 and n = 132), sensitivity was 100% (positive predictive value: 28.1% and 22.6%) and specificity was 48.9% and 80.8% (negative predictive value: 100.0%). Using a single examination, this model identified all infants who developed TR-ROP, on average, >1 month before diagnosis with moderate to high specificity. This approach could lead to earlier identification of incident severe ROP, reducing late diagnosis and treatment while simultaneously reducing the number of ROP examinations and unnecessary physiologic stress for low-risk infants.

Recovery of Body Awareness After Stroke: An Observational Study.

Background: Body awareness (BA) is a process that involves sensory awareness originating from the body's physiological states, processes and actions, and is shaped by one's attitudes, perceptions, beliefs and experience of social and cultural context. Impairments in body awareness after stroke are believed to be common and may be an important influence on recovery outcomes. However, recovery of body awareness is poorly understood and receives little consideration in rehabilitation.Aims: To investigate if body awareness changes over time following stroke; and identify if body awareness after stroke is associated with sensation, motor impairment, self-efficacy and quality of life.Methods: An exploratory longitudinal observational study was performed. Participants with a stroke diagnosis and associated motor impairment were recruited from an acute stroke unit. An assessment battery consisting of sensory and motor impairment and function, body awareness, self-efficacy and quality of life measures were used at baseline, 1, 3 and 6 months.Results: A total of 105 people with stroke were recruited. Most recovery in sensation and body awareness occurred within the first month after stroke (all p < 0.01). Sensation and body awareness were correlated with other clinical outcomes (motor impairment, self-efficacy and quality of life), demographics, and stroke specific clinical characteristics (all p < 0.01).Conclusions: This is the first study to track recovery of body awareness after stroke and investigate the relationship it may have in recovery of sensation, motor impairment and function, self-efficacy and quality of life. Further research is now warranted to continue investigation of body awareness and to develop effective stroke-specific assessment and intervention strategies.

Factors associated with consent for organ donation: a retrospective population-based study

Background:Optimizing the approach to and consent of potential organ donors maximizes patient autonomy and the availability of organs for transplants. We set out to identify modifiable factors associated with donation consent.Methods:We conducted a retrospective cohort study of consecutive adults (≥ 18 yr) referred for organ donation in Ontario between April 2013 and June 2019. We analyzed patient clinical data and demographics, data on substitute decision-makers and characteristics of the donation consent approach. Study outcomes were consent for organ donation and approach rate. We evaluated independent associations between consent and approach-and system-level factors.Results:We identified 34 837 referrals for organ donation, of which 6548 (18.8%) substitute decision-makers were approached for consent. Of these, 3927 (60.0% of approaches) consented for organ donation and 1883 (48.0% of consents) patients proceeded to be organ donors. The most common reason substitute decision-makers were not approached for consent in a case with donation potential was a late referral by the health care team (45.2%). Modifiable factors independently associated with consent included a telephone approach for consent (adjusted odds ratio [OR] 0.46, 95% confidence interval [CI] 0.35–0.58) and a collaborative approach by a physician and donation coordinator (adjusted OR 1.26, 95% CI 1.01–1.59).Interpretation:Consent for organ donation was associated with several modifiable factors. Organizations should target interventions to ensure timely referrals to organ donation organizations, increase in-person consent approaches and increase physician participation in the approach process.

Machine Learning Algorithms to Predict In-Hospital Mortality in Patients with Traumatic Brain Injury.

Traumatic brain injury (TBI) can lead to severe adverse clinical outcomes, including death and disability. Early detection of in-hospital mortality in high-risk populations may enable early treatment and potentially reduce mortality using machine learning. However, there is limited information on in-hospital mortality prediction models for TBI patients admitted to emergency departments. The aim of this study was to create a model that successfully predicts, from clinical measures and demographics, in-hospital mortality in a sample of TBI patients admitted to the emergency department. Of the 4881 TBI patients who were screened at the emergency department at a high-level first aid duty hospital in northern Taiwan, 3331 were assigned in triage to Level I or Level II using the Taiwan Triage and Acuity Scale from January 2008 to June 2018. The most significant predictors of in-hospital mortality in TBI patients were the scores on the Glasgow coma scale, the injury severity scale, and systolic blood pressure in the emergency department admission. This study demonstrated the effective cutoff values for clinical measures when using machine learning to predict in-hospital mortality of patients with TBI. The prediction model has the potential to further accelerate the development of innovative care-delivery protocols for high-risk patients.

Derivation and Internal Validation of a Score to Predict Dehydration Severity in Patients over 5 Years with Acute Diarrhea.

Diarrheal disease accounts for more than one million deaths annually in patients over 5 years of age. Although most patients can be managed with oral rehydration solution, patients with severe dehydration require resuscitation with intravenous fluids. Scoring systems to assess dehydration have been empirically derived and validated in children under 5 years, but none have been validated for patients over 5 years. In this study, a prospective cohort of 2,172 patients over 5 years presenting with acute diarrhea to International Centre for Diarrhoeal Disease Research, Dhaka Hospital, Bangladesh, were assessed for clinical signs of dehydration. The percent difference between presentation and posthydration stable weight determined severe (≥9%), some (3-9%), or no (<3%) dehydration. An ordinal regression model was derived using clinical signs and demographics and was then converted to a 13-point score to predict none (score of 0-3), some (4-6), or severe (7-13) dehydration. The Novel, Innovative Research for Understanding Dehydration in Adults and Kids (NIRUDAK) Score developed by our team included age, sex, sunken eyes, radial pulse, respiration depth, skin turgor, and vomiting episodes in 24 hours. Accuracy of the NIRUDAK Score for predicting severe dehydration, as measured by the area under the receiver operating characteristic curve, was 0.76 (95% confidence interval = 0.73-0.78), with a sensitivity of 0.78 and a specificity of 0.61. Reliability was also robust, with an Inter-Class Correlation Coefficient of 0.88 (95% confidence interval = 0.84-0.91). This study represents the first empirically derived and internally validated scoring system for assessing dehydration in children ≥5 years and adults with acute diarrhea in a resource-limited setting.

Telemedicine catches on: changes in the utilization of telemedicine services during the COVID-19 pandemic

To determine the degree of telemedicine expansion overall and across patient subpopulations and diagnoses. We hypothesized that telemedicine visits would increase substantially due to the need for continuity of care despite the disruptive effects of COVID-19. A retrospective study of health insurance claims for telemedicine visits from January 1, 2018, through March 10, 2020 (prepandemic period), and March 11, 2020, through October 31, 2020 (pandemic period). We analyzed claims from 1,589,777 telemedicine visits that were submitted to Independence Blue Cross (Independence) from telemedicine-only providers and providers who traditionally deliver care in person. The primary exposure was the combination of individual behavior changes, state stay-at-home orders, and the Independence expansion of billing policies for telemedicine. The comparison population consisted of telemedicine visits in the prepandemic period. Telemedicine increased rapidly from a mean (SD) of 773 (155) weekly visits in prepandemic 2020 to 45,632(19,937) weekly visits in the pandemic period. During the pandemic period, a greater proportion of telemedicine users were older, had Medicare Advantage insurance plans, had existing chronic conditions, or resided in predominantly non-Hispanic Black or African American Census tracts compared with during the prepandemic period. A significant increase in telemedicine claims containing a mental health-related diagnosis was observed. Telemedicine expanded rapidly during the COVID-19 pandemic across a broad range of clinical conditions and demographics. Although levels declined later in 2020, telemedicine utilization remained markedly higher than 2019 and 2018 levels. Trends suggest that telemedicine will likely play a key role in postpandemic care delivery.

The role of COVID‐19 survivor status and gender towards neutralizing antibody titers 1, 2, 3 months after Sinovac vaccine administration on clinical‐year medical students in Indonesia

Background: Sinovac was the first vaccine used in Indonesia against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, data regarding the effects of certain variables such as clinical demographics on antibody levels in individuals vaccinated with Sinovac are scarce. This study aimed to investigate the impact of gender and previous SARS-CoV-2 infection status on neutralizing antibody titers 1, 2, and 3 months after administration of the Sinovac vaccine.Method: A cross-sectional study was conducted from February to May 2021. Data on neutralizing antibody levels, previous SARS-CoV-2 infection status, and gender were retrieved from the monthly quantitative serology evaluation database of Siloam Hospitals Lippo Village, Tangerang, Indonesia. The role of each variable was analyzed using the t-test or Mann-Whitney U test, depending on data distribution.Result: Data from 350 participants were collected for the study. Participants with a history of a positive SARS-CoV-2 RT-PCR test had significantly higher neutralizing antibody titers in the first (144 U/mL, p = 0.036) and second months (144 U/mL, p = 0.005) after vaccination compared with those without a history of positive RT-PCR test. Female participants also had significantly higher neutralizing antibody titers in the first, second, and third months (43 U/mL, 42 U/mL, and 39 U/mL, respectively; p = 0.001, p = 0.002, and p = 0.003, respectively) after vaccination compared to males.Conclusion: COVID-19 survivor status and the female gender were associated with higher neutralizing antibody titers after Sinovac vaccine administration.

Characterization of residual lipid-rich plaques despite achieving LDL-C &amp;lt;1.8mmol/l with a statin in patients with coronary artery disease: insights from the REASSURE-NIRS registry

Abstract Introduction Recent studies have demonstrated favourable modification of lipidic plaque materials under achieving LDL-C &amp;lt;1.8mmol/l with a statin, which potentially accounts for its clinical benefit. However, coronary events still occur even under optimal LDL-C management. This may suggest the presence of residual lipid-rich coronary plaque despite on-treatment LDL-C &amp;lt;1.8mmol/l. Given that near-infrared spectroscopy (NIRS) enables quantitative evaluation of lipidic plaque in vivo, we employed this imaging modality to investigate characteristics and drivers of residual lipid-rich plaques in statin-treated patients with coronary artery disease (CAD) who achieved LDL-C &amp;lt;1.8mmol/l. Purpose To clarify the frequency, clinical demographics and factors associated with residual lipid-rich plaques under LDL-C &amp;lt;1.8mmol/l. Methods The REASSURE-NIRS registry is an on-going multi-center registry to enroll CAD subjects receiving NIRS/intravascular ultrasound-guided PCI. The current analysis included 133 statin-treated stable CAD patients with on-treatment LDL-C &amp;lt;1.8mmol/l from August 2015 to December 2020. The maximum 4-mm lipid core burden index (maxLCBI4mm) at culprit lesions was measured by NIRS imaging prior to PCI. Clinical characteristics were compared in patients with and without maxLCBI4mm ≥400 at culprit lesions. Results In the current study, 45% (=58/128) of study subjects exhibited maxLCBI4mm ≥400 at culprit lesions under on-treatment LDL-C &amp;lt;1.8 mmol/l. They were more likely to be female, whereas there were no differences in age and the frequency of risk factors. Most of study subjects received moderate to high-intensity statin (p=0.79), and over one-fourth of them were treated with ezetimibe (p=0.56). Under these lipid-lowering therapies, LDL-C level was significantly higher in patients with maxLCBI4mm ≥400 (Table). Additionally, a lower frequency of LDL-C &amp;lt;1.4mmol/l was observed in those exhibiting maxLCBI4mm ≥400 (31.0 vs. 45.7%), but this comparison failed to meet statistical significance (p=0.09). Despite LDL-C control with a statin, deterioration of coronary flow after PCI with stent implantation more frequently occurred in patients with maxLCBI4mm ≥400 (Table). Multivariate analysis demonstrated that an independent factor associated with maxLCBI4mm ≥400 was LDL-C level (OR=1.05; 95% CI=1.00–1.10, p=0.03), but not other lipid and clinical parameters. Conclusion Almost half of CAD subjects who achieved LDL-C level &amp;lt;1.8mmol/l still exhibited the accumulation of lipidic plaque materials within vessel wall. Given that LDL-C level was associated with this residual lipid-rich plaque features, our findings support current ESC-guideline recommended LDL-C goal (&amp;lt;1.4mmol/l) to optimize the secondary prevention in stable CAD patients.

Clinical impact of primary tumour 123ImIBG response to induction chemotherapy in children with high-risk neuroblastoma.

More than 50% children with high-risk neuroblastoma (HR-NBL) experience disease progression, which we hypothesise is due to non-response of primary tumour to treatment. Current imaging techniques are unable to characterise response in primary tumour (necrotic versus viable tissue) at diagnosis or follow-up. Compare clinico-histological characteristics between primary 123ImIBG-avid tumours that became entirely 123ImIBG-non-avid (responders) after induction chemotherapy (IC) versus primary 123ImIBG-avid tumour that remained 123ImIBG-avid (non-responders). Retrospective review of clinico-radiological data of children diagnosed with 123ImIBG-avid HR-NBL at our centre (2005-2016). Patients received Rapid COJEC IC and two additional courses of TVD if metastatic response was inadequate. Primary tumour 123ImIBG response was assessed qualitatively as positive, negative or intermediate at diagnosis and after IC. Post-surgical histopathology slices were marked considering percentage of viable tissue. Sixteen of 61 patients showed complete primary tumour 123ImIBG response, 20 partial response, while 25 no response. There was no statistically significant difference between clinical demographics of complete responders and group of non- or partial responders. Mean percentage of viable tumour cells was higher in non-responders than in complete responders (44.6% vs 20.6%; p = 0.05). Five-year EFS was significantly higher in complete responders than non-responders (43 ± 15% vs 7 ± 6%; p < 0.005). 123ImIBG response in primary HR-NBL correlates with amount of necrotic tissue, skeletal metastatic 123ImIBG response and outcome. An entirely 123ImIBG non-avid tumour can still harbour viable tumour cells. Therefore, our findings do not support utility of primary tumour 123ImIBG response in decision making regarding residual tumour surgery. Combining both, primary and metastatic 123ImIBG response will improve interpretability of clinical trial results.

Clinical profile of patients with endophthalmitis: A 16- year retrospective, cross-sectional study at tertiary care hospital in Western Saudi Arabia.

This study aimed to profile the clinical features and demographics of patients with endophthalmitis in a tertiary care center, Western region, Saudi Arabia. We used a retrospective cross-sectional case series at King Abdulaziz University Hospital. Endophthalmitis was diagnosed in a total of 14 eyes of 14 patients treated in our hospital between 2002 and 2018. The patients' medical records were reviewed to gather demographic and clinical data. The mean age of patients was 52.8 ± 19.2 years, and 50% of patients were male. The majority of endophthalmitis cases were post-ophthalmic surgery (50%), 35.7% were of endogenous origin, 7.2% were associated with corneal ulcer with perforation, and 7.2% were post open globe injury. Patients' admission to the hospital ranged from 2 to 10 days from symptoms occurrence with a median of 5 days. Half of the patients presented with no light perception vision, counting fingers in 14.2%, hand motion in 14.2%, light perception in 7.2%, and 20/300 in 7.2%. The final visual outcome improved in four cases (28.5%) with best corrected visual acuity of 20/40 reached in one patient. Post- ophthalmic surgery and endogenous endophthalmitis were the most common causes of endophthalmitis among our patients, with late presentation to the hospital and poor vision at presentation also being common findings. These findings highlight the necessity of proper patient education, after care and adherence to sterile techniques in ensuring that patients recover successfully from ophthalmic surgery.

Clinical characteristics and demographics of patients with dementia treated at the NPZR

Dementia is considered as an important public health issue with high costs for the treatment of the patients. Previous studies demonstrate that low education and the age of people were significantly associated with a greater risk for dementia (Sharp & Gatz, 2011 and Gao, et al., 1998). Therefore, this study aims to analyze the relationship between sociodemographic parameters as well as the prevalence of depression of patients with dementia treated at the NPZR.

Characteristics, treatment patterns, and economic burden of patients with metastatic cervical cancer receiving systemic anticancer therapy.

51 Background: In 2021, 14,480 patients are estimated to be diagnosed with cervical cancer in the US; 16% of patients are expected to have metastatic disease for whom the 5-year survival rate is 17.6% per SEER estimates. Patients with metastatic cervical cancer (mCC) are treated mainly with systemic therapy. This study aims to describe the clinical characteristics, demographics, treatment patterns, and economic burden of patients with mCC receiving systemic therapy. Methods: Eligible women had been diagnosed with cervical cancer, as evidenced by &gt;2 outpatient or &gt;1 inpatient claim in the Optum Research Database from January 2014 through January 2020. Patients were included if they had metastasis within 6 months before or after cervical cancer diagnosis, with evidence of systemic treatment on or after the latter of a claim date for cervical cancer disease or metastatic disease. The index date was the first-line treatment initiation date. Patients were required to have ≥6 months of pre-index continuous enrollment. The top 3 treatment regimens and median treatment duration by line of therapy were described. All-cause per-patient-per-month (PPPM) costs (2019 US dollars), including plan and patient paid amounts, were reported for full follow-up period from first-line and second-line therapy initiation. Results: The study sample consisted of 778 patients (mean age, 59 years; commercial, 58%; Medicare Advantage, 42%). The mean (median) follow-up period was 14 (9) months. Top baseline comorbidities were diseases of the urinary system (71%) and diseases of the female genital organs (70%), and the median Charlson comorbidity index was 7. In the first line, 80% of patients received platinum-based therapy and 23% received bevacizumab (bev). Of 778 patients, only 294 (38%) received second-line therapy, with 34% receiving bev. Top first-line treatment regimens were carboplatin + paclitaxel (27%), cisplatin (21%), and bev + carboplatin + paclitaxel (10%); the median (95% CI) duration of treatment was 3.4 (3.1-3.7) months. Top second-line treatment regimens were bev + carboplatin + paclitaxel (13%), carboplatin + paclitaxel (11%), and pembrolizumab (6%); the median duration of treatment was 3.8 (3.1-4.2) months. Mean all-cause total PPPM costs were $19,519 from first-line and $22,660 second-line therapy initiation (table). Conclusions: This study indicates that real-world mCC patients have short treatment durations and significant economic burden with first-line and second-line therapy. Novel therapies associated with greater clinical benefits in patients with mCC may provide economic benefit.[Table: see text]

Prognostic Prediction of BRCA Mutations by 18F-FDG PET/CT SUVmax in Breast Cancer

Objectives:This study aimed to investigate the prognostic prediction of germline BRCA1 and BRCA2 mutations by comparing the maximum standardized uptake value (SUVmax) obtained from 18fluoride-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT), which is considered a prognostic factor in breast cancer (BC).Methods:Retrospective interdisciplinary laboratory results of 92 patients with BC who had germline BRCA1 or BRCA2 mutation profiles and underwent 18F-FDG PET/CT were compared. Genotyping was made by next-generation sequencing, and PET/CT scans were re-evaluated. The histopathological data, genetic results, and clinical demographics of all patients were recorded. Patients were divided into two groups in accordance with the presence of germline BRCA1 and/or BRCA2 mutations. Between-group statistical comparison was performed.Results:In PET/CT performed for primary staging, patients with BRCA-positive BC had significantly higher SUVmax (p=0.039), larger tumor size (p=0.025), and presence of axillary nodal metastases (p=0.023) than patients with BRCA-negative BC. Although the Ki-67 index was higher in the BRCA-positive group than BRCA-negative group, this difference was not significant (p=0.157). Moreover, in the BRCA-positive and negative groups, SUVmax, Ki-67 index, and tumor size, grade, and stage were significantly correlated with each other.Conclusion:The results of this study showed a strong association between BRCA mutations and SUVmax, which indicates the poor prognosis of BC.

Effects on annual income changes after radical radiotherapy versus after prostatectomy in patients with localized prostate cancer with a specific employment status: A web-based pilot study

Men with localized prostate cancers are insured for undergoing radical radiotherapy or prostatectomy. However, limited information is available on the influence of cancer treatments on patients’ employment status in Japan. Therefore, in this web-based survey, we aimed to compare the effects of post-treatment changes on the annual income of patients with prostate cancer after undergoing radical radiotherapy and prostatectomy and to identify the risk factors associated with the decrease in annual income. We investigated the clinical characteristics and demographics including pre-treatment working status, self-employment, non-regular employment, working for wage or salary, and joblessness of patients with localized prostate cancer. Multivariable logistic regression was performed to analyze the effects of various factors on the change in the annual income of self-employed and non-regularly employed workers. Seventy-eight eligible patients with localized prostate cancer had undergone radiotherapy, and 128 patients had undergone prostatectomy. Among self-employed and non-regularly employed workers, post-treatment income decline rates in those who underwent radiotherapy were smaller but not significant (12% vs. 42%, P = 0.074). Multivariable logistic regression analysis revealed that initial treatment for prostate cancer was the only significant risk factor for the post-treatment income decline among self-employed and non-regularly employed workers. Radiotherapy was associated with a smaller decrease in income (odds ratio, 0.22; 95% confidence interval, 0.052–0.95; P = 0.042). Our novel results implied the effectiveness of radiotherapy in preventing post-treatment income decline among patients with prostate cancer based on specific employment status: self-employed or non-regularly employed.

Estrogen Attenuates Chronic Stress-Induced Cardiomyopathy by Adaptively Regulating Macrophage Polarizations via β2-Adrenergic Receptor Modulation.

Clinical demographics have demonstrated that postmenopausal women are predisposed to chronic stress-induced cardiomyopathy (CSC) and this has been associated with the decrease of estrogen. Meanwhile, recent studies have implicated unsolved myocardial proinflammatory responses, which are characterized by enormous CD86+ macrophage infiltrations as an underlying disease mechanism expediting the pathological remodeling of the heart during chronic stress. However, we had previously demonstrated that estrogen confers cardioprotection via the modulation of cardiomyocytes β2-adrenoceptors (β2AR)-Gs/Gi pathways during stress to lessen the incidence of stress-induced cardiovascular diseases in premenopausal women. Intriguingly, macrophages express β2AR profoundly as well; as such, we sought to elucidate the possibilities of estrogen modulating β2AR-Gs/Gi pathway to confer cardioprotection during stress via immunomodulation. To do this, ovariectomy (OVX) and sham operations (Sham) were performed on female Sprague-Dawley (SD) rats. Two weeks after OVX, the rats were injected with 40 μg/kg/day of estradiol (E2). Next, on day 36 after OVX, chronic stress was induced by a daily subcutaneous injection of 5 mg/kg/day of isoproterenol (ISO). The effect of E2 on relevant clinical cardiac function indexes (LVSP, LVEDP, + dp/dt and −dp/dt), myocardial architecture (cardiomyocyte diameter and fibrosis), β2AR alterations, and macrophage (CD86+ and CD206+) infiltrations were assessed. In vitro, peritoneal macrophages (PMΦ) were isolated from wild-type and β2AR-knockout female mice. The PMΦ were treated with ISO, E2, and β2AR blocker ICI 118,551 for 24 h, and flow cytometric evaluations were done to assess their phenotypic expression. E2 deficiency permitted the induction of CSC, which was characterized by cardiac dysfunctions, maladaptive myocardial hypertrophy, unresolved proinflammatory responses, and fibrosis. Nonetheless, E2 presence/supplementation during stress averted all the aforementioned adverse effects of chronic stress while preventing excessive depletion of β2AR. Also, we demonstrated that E2 facilitates timely resolution of myocardial proinflammation to permit reparative functions by enhancing the polarization of CD86+ to CD206+ macrophages. However, this adaptive immunomodulation is hampered when β2AR is inhibited. Taken together, the outcomes of this study show that E2 confers cardioprotection to prevent CSC via adaptive immunomodulation of macrophage phenotypes, and β2AR-mediated signaling is crucial for the polarizations of CD86+ to CD206+ macrophages.

Frequency and outcomes of gastrointestinal symptoms in patients with Corona Virus Disease-19.

ObjectivesTo characterize the frequency and association of gastrointestinal (GI) symptoms with outcomes in patients with corona virus disease 2019 (COVID-19) admitted to the hospital.MethodsRecords were retrospectively collected from patients admitted to a tertiary care center in Washington, D.C., with confirmed COVID-19 from March 15, 2020 to July 15, 2020. After adjusting for clinical demographics and comorbidities, multivariate logistic regression analysis was performed.ResultsThe most common presenting symptoms of COVID-19 in patients that were admitted to the hospital were cough (38.4%), shortness of breath (37.5%), and fever (34.3%), followed by GI symptoms in 25.9% of patients. The most common GI symptom was diarrhea (12.8%) followed by nausea or vomiting (10.5%), decreased appetite (9.3%), and abdominal pain (3.8%). Patients with diarrhea were more likely to die (odds ratio [OR] 2.750; p = 0.006; confidence interval [CI] 1.329–5.688), be admitted to the intensive care unit (ICU) (OR 2.242; p = 0.019; CI 1.139–4.413), and be intubated (OR 3.155; p = 0.002; CI 1.535–6.487). Additional outcomes analyzed were need for vasopressors, presence of shock, and acute kidney injury. Patients with diarrhea were 2.738 (p = 0.007; CI 1.325–5.658), 2.467 (p = 0.013; CI 1.209–5.035), and 2.694 (p = 0.007; CI 1.305–5.561) times more likely to experience these outcomes, respectively.ConclusionsScreening questions should be expanded to include common GI symptoms in patients with COVID-19. Health care providers should note whether their patient is presenting with diarrhea due to the potential implications on disease severity and outcomes.

Management, outcomes and survival of an Australian IgG4-SC cohort: The MOSAIC study.

IgG4 sclerosing cholangitis (IgG4-SC) is the biliary component of the multisystem IgG4-related disease. We aimed to investigate the clinical features, demographics, treatment response and outcomes of IgG4-SC in a large Australian cohort. We conducted nationwide retrospective cohort via the Australian Liver Association Clinical Trials Network (ALA-CRN). 39 sites were invited to participate. IgG4-SC was defined by the clinical diagnostic criteria established by the Japanese Biliary Association in 2012. Data were collected on patient demographic, clinical and laboratory information, presenting features, response to therapy and clinical outcomes. 67 patients meet inclusion criteria from 22 sites. 76% were male with mean age of 63.3±14.5years and a median IgG4 level of 3.6g/L [0.09-67.1]. The most frequent presenting symptom was jaundice (62%) and abdominal pain (42%) and Type 1 biliary stricturing (52%) at the distal common bile duct was the most frequent biliary tract finding. Prednisolone was used as a primary treatment in 61 (91%) and partial or complete response occurred in 95% of subjects. Relapse was common (42%) in those who ceased medical therapy. After a median follow up of 3.9years there was one hepatocellular carcinoma and no cholangiocarcinomas. Our study confirms the preponderance of IgG4-SC in males and highlights the steroid response nature of this condition although relapse is common after steroid cessation. Progression to malignancy was uncommon.
