AbstractObjectiveLactate levels are increasingly used to guide resuscitation efforts. Some surgical literature suggests that tourniquet use during phlebotomy falsely elevates results, although studies in healthy volunteers have not demonstrated this. The purpose of this study was to determine in clinical practice whether tourniquet use during the drawing of a lactate results in significantly altered levels compared to the result of a level drawn without a tourniquet.MethodsA prospective cohort study was carried out on emergency department patients whose clinical presentation led a physician to order a lactate level. Written informed consent was obtained from patients or their proxies. Study lactates were obtained using a tourniquet during the draw sequence of other laboratory studies. Lactate levels for clinical use were drawn per hospital protocol with no tourniquet. The time of lactate measurements and patient demographic information were recorded. Lactate levels for each patient were compared with the Wilcoxon Rank-Sum Test.Results40 patients were consented and enrolled. The median clinical lactate level was 1.9 (interquartile range 1.5-2.6), and the median study lactate level was 1.9 (interquartile range 1.4-2.7). There was no difference between paired lactate values (p=0.95).ConclusionsTourniquet use appears to have no impact on measured lactate levels. Our findings suggest that current practices at many institutions regarding lactate collection are likely too stringent and should be changed.

Abstract Objective The clinical interpretation of lactate ≤ 2.00 mmol/L in emergency department (ED) patients is not well characterized. This study aims to determine the optimal cutoff value for lactate within the reference range that predicts in-hospital mortality among ED patients with initial serum lactate levels within the reference range. Methods This was a retrospective study of adult patients presenting to a tertiary ED between the dates of January 1, 2014 and June 30, 2019 with an initial serum lactate level less than 2.00 mmol/L. The primary outcome was in-hospital mortality. Youden’s index was utilized to determine the optimal threshold that predicts mortality. Patients above the threshold were labeled as having relative hyperlactatemia. A multivariate logistic regression was performed to determine the association between relative hyperlactatemia and in-hospital mortality. Subgroup analyses were done to further examine the interaction between relative hyperlactatemia and hospital mortality. Results During the study period, 1638 patients were included. The mean age was 66.9 ± 18.6 years, 47.1% of the population were female, and the most prevalent comorbidity was hypertension (56.7%). The mean lactate level at presentation was 1.5 ± 0.3 mmol/L. In-hospital mortality was 3.8% in the overall population and 16.2% were admitted to the ICU. A lactate of 1.33 mmol/L was found to be the optimal cutoff that best discriminates between survivors and non-survivors. Relative hyperlactatemia was an independent predictor of in-hospital mortality (OR 1.78 CI1.18-4.03; p 0.02). Finally, Relative hyperlactatemia was associated with increased mortality in patients without hypertension (4.7% versus 1.1%; p 0.008), as well as patients without diabetes or COPD. Conclusion The optimal cutoff of initial serum lactate that discriminates between survivors and non-survivors is in the ED 1.33 mmol/L. Relative hyperlactatemia is associated with increased mortality in emergency department patients, and this interaction seems to be more important in healthy patients.

Abstract Background Coronavirus disease highly contagious, is prevalent in all age and sex groups infecting the respiratory system. The present study seeks to investigate the epidemiology and effective factors in mortality of patients with COVID-19 in Ardabil province, northwestern Iran. Methods In a retrospective study, the hospitalized patients with laboratory-diagnosed COVID-19 between February to August 2020 were enrolled. The data registration portal was designated according to Iranian Ministry of Health and Medical Education guidelines. In this portal, demographic information, clinical presentation, laboratory and imaging data were registered for patients in all hospitals in the same format. The Hosmer-Lemeshow strategy was used for variable selection in a multiple model. Results Of the patients involved 2812(50.3%) were male and 150 (2.7%) had contact with a confirmed case of COVID-19 in the last 14 days. Pre-existing comorbidity was reported in 1310 (23.4%) patients. Of all patients, 477(8.5%) died due to COVID-19. the result of the multiple logistic regression model indicated that after adjusting for other factors, higher age (OR = 3.11), fever or chills (OR = 1.61), shortness of breath (OR = 1.82), fatigue (OR = 0.71), headache (OR = 0.64), runny nose (OR = 1.54), Skeletal muscle pain (OR = 1.53), hospitalization (OR = 5.66), and hospitalization in ICU (OR = 5.12) were associated with death. Conclusions Hospitalization had the strongest effect on mortality followed by hospitalization in ICU, and higher age. This study showed that having some extra-pulmonary symptoms in contrast with pulmonary symptoms can predict as good prognostic factors.

Objectives. To correlate the initial and maximal lactate levels with the occurrence of intracranial hemorrhage (ICH) and survival in patients treated with extracorporeal life support (ECLS). Design. Retrospective chart review. Setting. Pediatric intensive care unit. Patients. Eighty-two neonatal patients placed on ECLS for respiratory failure due to sepsis, meconium aspiration, or persistent pulmonary hypertension of the newborn. Measurements. The initial lactate level measured within 6 hours of initiating ECLS and the maximal lactate level measured throughout the ECLS course were collected. Lactate levels were described as mean lactate ± SE (mM). Head ultrasound reports and survival were reviewed. Platelet counts and activated clotting times (ACTs) were examined. Results. The mean initial and maximal lactate levels were higher in ECLS patients who developed ICH (initial: 10 ± 1.7 mM vs 6.4 ± 0.8 mM, p = .05 and maximal: 12.4 ± 2.5 mM vs 7.9 ± 0.8 mM, p = .04). Initial and maximal lactate levels were also elevated in nonsurvivors (initial: 11.7 ± 3 mM vs 6.4 ± 0.7 mM, p = .01 and maximal: 14.8 ± 3.3 mM vs 7.8 ± 0.8 mM, P < .01). Platelet counts and ACT did not differ in patients with and without ICH. Conclusions. Lactate is a useful marker for the development of ICH in ECLS patients. In addition, elevated lactates during ECLS identify a subgroup of patients with poor outcome. Prospective studies are needed to determine whether the incorporation of this information into pre-ECLS and ECLS management will decrease the occurrence of ICH and improve survival.

Genital warts (GW) are mucosal or skin lesions caused by sexual transmission of human papillomavirus (HPV). This study estimates the frequency of GW cases in physicians’ clinics and physicians’ usual practices of GW referral and diagnosis in Peru. Participants in this study were a convenience sample of 100 physicians in five specialties: primary care (17), gynecology (37), urology (10), dermatology (31), and infectious diseases (5). Physicians completed a survey and daily log of all patients aged 18–60 years seen over ten days in their offices located in Peru. The survey recorded GW referral patterns and the daily log recorded patient demographic information and GW diagnosis. Among 12,058 patients, the annual GW prevalence (95% confidence interval [CI]) was 2.28% (2.02–2.56) and cumulative incidence (95% CI) was 1.60% (1.38–1.84). Physicians reported that most GW patients were direct consult (73.5% of male and 67.9% of females) and physicians treated most GW patients themselves (73.4% of males and 76.7% of females). As reported, the most common reasons for referring were ‘serious cases requiring more specialized treatment’ (73.2% of male and 72.2% of female) and ‘lack of resources to treat’ (26.8% of male and 27.8% of female). We conclude that GW cases are commonly seen by physicians in Peru.

Objective: To evaluate a novel outpatient pharmacist consult service in a large academic medical center. Setting: Four outpatient pharmacies that are part of a large academic medical center Methods: An outpatient pharmacist consult order was created and embedded in the electronic medical record (EMR). Medical center providers utilized this consult order when identifying patients in need of specific services provided by outpatient pharmacists. Descriptive data about each individual consult was collected including number completed, type of service, and duration. Rate of accepted pharmacy recommendations and patient cost savings were also evaluated. A survey was administered at the completion of the study period to assess provider and pharmacist satisfaction with the service.  Patient demographic information was collected for those who had a documented completed consult. Results: A total of 193 consults were completed: 137 immunizations, 37 care affordability, 15 education, 3 polypharmacy and 1 OTC recommendation. 89% of completed consults took pharmacists 20 minutes or less to complete. Of completed care affordability consults (n=31), 55% of patients saved between $100 - $500 per medication fill. Of providers who completed a survey and utilized the service (n=12), 83.3% were extremely satisfied and 16.7% were satisfied with it. The provider acceptance rate of pharmacist’s recommendations was 74%. Conclusion: Implementation of an outpatient pharmacist consult service provided an alternative method for the utilization of pharmacist provided MTM services in outpatient pharmacies at a large academic medical center. The service was well received by both providers and pharmacists.

Abstract Background The clinical presentation of primary hyperparathyroidism (PHPT) has changed greatly during the past few decades. Our aim was to evaluate whether the clinical presentation at diagnosis differed according to age. Methods We evaluated retrospectively a monocentric series of 462 consecutive patients with PHPT, dividing them according to a cutoff of 65 years of age. Results No differences were found in the mean serum PTH, calcium, or vitamin D levels. In older patients (n = 212; 45.9%), the urinary calcium levels were significantly lower (median, 205 mg/24 hour; interquartile range, 220 mg/24 hour) compared with those in younger patients (median, 308 mg/24 hour; interquartile range, 233 mg/24 hour). In addition, renal involvement was significantly less frequent (25% vs 49.2%), and bone involvement significantly more frequent (58% vs 44%) in older patients compared with younger patients. The clinical presentation was significantly different between the two age groups, with a lower frequency of symptomatic forms and a greater frequency of asymptomatic forms not meeting surgical criteria in the older patients (44.4% vs 57.2% and 18.4% vs 5.6%, respectively). Osteoporosis was significantly more frequent in the older adults than in their younger counterparts. The most affected bone site was the forearm in older adults and the lumbar spine in younger ones (50.3% and 50.5%, respectively). Conclusion The clinical presentation of PHPT differs according to age, and this difference can affect the selection of management modalities.

Patient Demographic Information

Current research on bilingual aphasia highlights the paucity in recommendations for optimal rehabilitation for bilingual aphasic patients (Edmonds & Kiran, 2006; Roberts & Kiran, 2007). In this paper, we have developed a computational model to simulate an English–Spanish bilingual language system in which language representations can vary by age of acquisition (AoA) and relative proficiency in the two languages to model individual participants. This model is subsequently lesioned by varying connection strengths between the semantic and phonological networks and retrained based on individual patient demographic information to evaluate whether or not the model's prediction of rehabilitation matches the actual treatment outcome. In most cases the model comes close to the target performance subsequent to language therapy in the language trained, indicating the validity of this model in simulating rehabilitation of naming impairment in bilingual aphasia. Additionally, the amount of cross-language transfer is limited both in the patient performance and in the model's predictions and is dependent on that specific patient's AoA, language exposure and language impairment. It also suggests how well alternative treatment scenarios would have fared, including some cases where the alternative would have done better. Overall, the study suggests how computational modeling could be used in the future to design customized treatment recipes that result in better recovery than is currently possible.

Introduction: Patients with elevated serum lactate levels may be at risk for considerable morbidity and mortality and require a prompt, thoughtful and systematic approach for diagnosis and treatment. Aim: To find an association of on admission arterial serum lactate with outcome in Intensive Care Unit (ICU) patients. Materials and Methods: This observational cohort study was conducted on 168 patients at Poona Hospital and Research Centre, Pune, India, between June 2018 to November 2019 after obtaining Institutional Ethical Clearance. The patients included were above 18 years of age who had Systolic Blood Pressure (SBP) <90 mmHg, Heart Rate (HR) >100/min and Respiratory Rate (RR) >20/min. The arterial serum lactate level were examined on the day of admission, 12 hours and 24 hours. The need of ionotropic support, duration of ICU stay and mortality in one month was noted. The primary outcome measures were to study the association of on admission arterial serum lactate level with a duration of ICU stay and in-hospital mortality, whereas the secondary outcome measure was to study the association of on admission arterial serum lactate with the requirement of ionotropic support. Analysis of data was done using Statistical Package for Social Sciences for Windows, version 20.0. Results: The incidence in-hospital mortality was 20 (22.7%) out of 88 and 3 (3.8%) out of 80 in patients whose serum lactate levels on admission were >36 mg/dL and ≤36 mg/dL, respectively (p-value=0.002). The median duration of ICU stay was six and three days in patients whose serum lactate levels on admission were >36 mg/dL and ≤36 mg/dL, respectively (p-value=0.001). A 87 (98.9%) patients whose serum lactate levels >36 mg/dL on admission had the higher requirement of inotropes as compared to 35 (50.7%) patients whose serum lactate levels were ≤36 mg/dL. The percentage of patients whose serum lactate level >36 mg/dL, had a significantly higher Quick Sequential Organ Failure Assessment (qSOFA) scores and higher Shock Index (SI). There was a statistically significant positive correlation between serum lactate levels and qSOFA score (r=0.555) and SI (r=0.559). Conclusion: Initial serum lactate level was associated with higher in-hospital mortality, the higher requirement of inotropic support and longer duration of ICU stay.
