On March 11, 2020, the World Health Organization declared the coronavirus disease 2019 (COVID-19) a pandemic, and in the weeks following, public health organizations, medical associations, and governing bodies throughout the world recommended limiting contact with others to "flatten the curve" of COVID-19. Although both ischemic and hemorrhagic strokes have been reported with COVID-19, there has been anecdotal suggestion of an overall decrease in stroke admissions. To date, the effects of any pandemic on telestroke service lines have not been described. The purpose of this cross-sectional analysis of telestroke activations in the 30 days before and after the declaration of the COVID-19 pandemic is to describe the difference in case volumes of telestroke activations, the characteristics of patients, and treatment recommendations between the 2 time frames. We found a 50.0% reduction in total telestroke activations between the predeclaration group (142 patients) and the postdeclaration group (71 patients). There were no statistically significant differences in age (P=.95), sex (P=.10), diagnosis (P=.26), or regional variations (P=.08) in activation volumes. The percentage of patients for whom we recommended urgent stroke treatment with intravenous alteplase, mechanical thrombectomy, or both decreased from 44.4% (28 of 63) to 33.3% (11 of 33). The reasons for the sunstantial decrease in telestroke activations and urgent stroke treatment recommendations are likely multifactorial but nevertheless underscore the importance of continued public health measures to encourage patients and families to seek emergency medical care at the time of symptom onset.The possibility of seasonality of COVID-19 is being discussed; we show clinical microbiology laboratory data illustrating seasonality of coronaviruses 229E, HKU1, NL63, and OC43. The data shown are specific to the 4 studied coronaviruses and may or may not generalize to COVID-19.Among candidate drugs to treat coronavirus disease 2019 (COVID-19), the combination of hydroxychloroquine (HCQ) and azithromycin (AZ) has received intense worldwide attention. Even as the efficacy of this combination is under evaluation, clinicians have begun to use it largely. As these medications are known to prolong the QT interval, we analyzed serial electrocardiograms recorded in patients hospitalized for COVID-19 pneumonia and treated with HCQ + AZ. Fifty consecutive patients received the combination of HCQ (600 mg/d for 10 days) and AZ (500 mg/d on day 1 and 250 mg/d from day 2 to day 5). Twelve-lead electrocardiograms were recorded before treatment, at day 3, at day 5, and at discharge. The median age of patients was 68 years (interquartile range, 53-81 years); 28 (56%) were men. The main comorbidities were hypertension (36%; n=18) and diabetes (16%; n=8). The mean corrected QT (QTc) interval was 408 ms at baseline and increased up to 437 ms at day 3 and to 456 ms at day 5. Thirty-eight patients (76%) presented short-term modifications of the QTc duration (>30 ms). Treatment discontinuation was decided in 6 patients (12%), leading to QTc normalization in 5 of them. No deaths and no cardiac arrhythmic events were observed in this cohort. Our report confirms that a short duration treatment with HCQ + AZ modifies the QTc interval. The treatment had to be discontinued for QTc modifications in 12% of patients. Nevertheless, in inpatients hospitalized for COVID-19, we did not observe any clinically relevant consequences of these transitory modifications. In conclusion, when patients are treated with HCQ + AZ, cardiac monitoring should be regularly performed and hospital settings allow monitoring under in safe conditions.
To characterize the clinicopathologic findings, comorbidities, and treatment outcomes of women with lichen planopilaris (LPP).
In this retrospective review of women with LPP at Mayo Clinic from 1992 to 2016, we searched for scarring alopecia in all female patients aged 1 to 100 years from January 1, 1992, through December 31, 2016. Men were excluded from this study to more accurately determine the association of hormonal factors in LPP pathogenesis. Two hundred thirty-two patients were included as they met diagnostic criteria for LPP based on clinicopathologic correlation, with 217 having confirmatory biopsies.
We identified 232 women with LPP (mean age, 59.8 years). Of those, 92.7% (215) presented with hair loss; 23.7% (55) had preceding inflammation; 30.6% (71) had thyroid disease, including hypothyroidism (23.2%; 54); and 9.4% (22) had vitamin D deficiency. Incidence of depression and anxiety was 45.7% (106) and 41.8% (97), respectively. History of total abdominal hysterectomy/bilateral salpingo-oophusly reported, LPP is associated with thyroid disease. We also found higher rates of depression, anxiety, nutritional deficiencies, and skin cancer than reported in the general population.
To characterize the use of cystatin C (cysC) across and within hospitals.
This 2-part study first evaluated access to cysC testing across 129 hospitals in the state of Minnesota, using a telephone-based survey. mTOR inhibitor Second, granular data from a single center (Mayo Clinic) with on-site, rapid-turnaround testing (<1 day) and automated estimated glomerular filtration rate (eGFR) reporting was used to describe temporal patterns. The characteristics of hospitals that offered cysC testing and of patients who underwent rapid cysC testing at Mayo Clinic between January 1, 2011, and March 31, 2018, were described. Poisson regression analyzed temporal trends in cysC testing.
Of the 114 hospitals (88%) that responded to the statewide survey, cysC was available in 91(80%), but only 3 of 91 (3%) reported a turnaround time of <1 day. At Mayo Clinic, cysC use increased from 0.74 tests per 1000 patient-days in 2011 to 14 tests per 1000 patient-days in 2018 (P=.004). Of the 3774 patients with cysC tests, the mean first available eGFR was 46 mL/min per 1.73 m
using cysC and 59 mL/min per 1.73 m
using serum creatinine (P<.001). CysC testing was used across all intensities of care and was ordered by a variety of specialties. Nephrology was consulted in only 42% of cases.
In the hospital, rapid-turnaround cysC testing is necessary for practical use but was not widely available in Minnesota. When available, a marked increase in cysC testing was observed over the study timeframe. Additional research is needed to determine optimal strategies for implementation of cysC within hospitals.

To perform a systematic review and meta-analysis evaluating the prevalence of gastrointestinal (GI) symptoms and mortality in patients with coronavirus disease 2019 (COVID-19) diagnosed.
A systematic search of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus was performed from December 1, 2019 to May 7, 2020. Observational studies including adults with COVID-19 infection and reporting GI symptoms were included. The primary outcome was assessing the weighted pooled prevalence (WPP) of GI symptoms in patients with COVID-19 infection. Secondary outcomes were WPP of overall mortality, and mortality in patients with COVID-19 infection with GI symptoms.
A total of 78 studies with 12,797 patients were included. Among GI symptoms (at onset of illness in 6, at admission in 17, data given separately for both in 3, and data unavailable in 52 studies), the WPP of diarrhea was 12.4% (95% CI, 8.2% to 17.1%), I
=94%; nausea and/or vomiting, 9.0% (95% CI, 5.5% to 12.9%), I
=93%; loss of appetite, 22.3% (95% CI, 11.2% to 34.6%, I
=94%; and abdominal pain, 6.2% (95% CI, 2.6% to 10.3%), I
=92%. Mortality among patients with GI symptoms (0.4%; 95% CI, 0% to 1.1%; I
=74%) was similar to overall mortality (2.1%; 95% CI, 0.2% to 4.7%; I
=94%), P=.15. Most studies had high risk of bias and overall quality of evidence was low to very low for all outcomes.
Gastrointestinal symptoms are seen in up to 1 in 5 patients with COVID-19 infection. More high-quality evidence is needed to confirm these findings and explore factors causing mortality in these patients.

To estimate the prevalence of olfactory and gustatory dysfunctions (OGDs) among patients infected with novel coronavirus disease 2019 (COVID-19).
A systematic review was conducted by searching MEDLINE, EMBASE, and the preprint server MedRxiv from their inception until May 11, 2020, using the terms anosmia or hyposmia or dysosmia or olfactory dysfunction or olfaction disorder or smell dysfunction or ageusia or hypogeusia or dysgeusia or taste dysfunction or gustatory dysfunction or neurological and COVID-19 or 2019 novel coronavirus or 2019-nCoV or SARS-CoV-2. The references of included studies were also manually screened. Only studies involving patients with diagnostic-confirmed COVID-19 infection were included. Random-effects meta-analysis was performed.
Twenty-four studies with data from 8438 patients with test-confirmed COVID-19 infection from 13 countries were included. The pooled proportions of patients presenting with olfactory dysfunction and gustatory dysfunction were 41.0% (95% CI, 28.5% to 53.y.
To confirm whether a relationship exists between male sex and coronavirus disease 2019 (COVID-19) mortality and whether this relationship is age dependent.
We queried the COVID-19 Research Network, a multinational database using the TriNetX network, to identify patients with confirmed COVID-19 infection. The main end point of the study was all-cause mortality.
A total of 14,712 patients were included, of whom 6387 (43%) were men. Men were older (mean age, 55.0±17.7 years vs 51.1±17.9 years; P<.001) and had a higher prevalence of hypertension, diabetes, coronary disease, obstructive pulmonary disease, nicotine dependence, and heart failure but a lower prevalence of obesity. Before propensity score matching (PSM), all-cause mortality rate was 8.8% in men and 4.3% in women (odds ratio, 2.15; 95% CI, 1.87 to 2.46; P<.001) at a median follow-up duration of 34 and 32 days, respectively. In the Kaplan-Meier survival analysis, the cumulative probability of survival was significantly lower in men than in w in men.
To present our center's experience with a maintenance treatment algorithm for intravenous bevacizumab that allows for personalized therapy decisions.
We reviewed all patients treated with intravenous bevacizumab for hereditary hemorrhagic telangiectasia-related bleeding and/or high-output cardiac failure (HOCF) from January 1, 2013, to July 1, 2019, at the Mayo Clinic, Rochester, Minnesota. Data regarding subsequent bevacizumab dosing were abstracted.
A total of 57 patients (n=40, 70.2% females) were identified with a median age of 65 (55 to 74; range, 37 to 89) years. High-cardiac output state was present in 21 patients (36.8%) and 10 (17.5%) were treated with intravenous bevacizumab primarily for HOCF. The median duration of follow-up after completion of the initial intravenous bevacizumab treatment was 25 (12.3 to 40.8; range, 0.1 to 65.4) months. A total of 20 (35.1%) patients with a median follow-up of 13.5 (range, 0 to 48.4) months required no maintenance dosing throughout the duration of follow-up.
