Nurses are the largest group of healthcare workers in Africa. By adequately equipping nurses to identify, intervene and care for emergency conditions, emergency healthcare systems can be strengthened. To address this need, a nursing working group was formed within the African Federation for Emergency Medicine (AFEM). The aim of this international emergency nursing group was to develop a guiding document to help improve emergency nursing skills within Africa. Using this guiding document, a group of Tanzanian clinical nurse trainers was selected to develop a context specific short course. They used this guiding document as a foundation to improve skill development. The pilot course was well received and has since expanded to training in five regions within the United Republic of Tanzania. The clinical nurse trainers leading the course, are supported by a mentorship programme with competent educators within a global emergency nursing infrastructure. This course, a combination of local knowledge, formal mentorship programs, and international nursing support, demonstrates that investing in the improvement of emergency nursing skills can have high impact results with low-cost. This will ultimately improve emergency care on the continent.

Summary: Background: Post-tuberculosis (TB) sequelae present a significant challenge in the management of TB survivors, often leading to persistent health issues even after successful treatment. Identifying risk factors associated with post-TB sequelae is important for improving outcomes and quality of life of TB survivors. This systematic review and meta-analysis aims to identify risk factors associated with long-term physical sequelae among TB survivors. Methods: We systematically searched Medline, Embase, PROQUEST, and Scopus for studies on long-term physical sequelae among TB survivors up to December 12, 2023. The primary outcome of interest was to quantify risk factors of long-term physical sequelae (i.e., respiratory, hepatic, hearing, neurological, visual, renal, and musculoskeletal sequelae). We included all forms of TB patients who experienced long-term physical sequelae. We used narrative synthesis for risk factors reported once and random-effect meta-analysis for primary outcomes with two or more studies. Findings were presented with odds ratios (OR) and 95% confidence intervals (CI). Publication bias was assessed using funnel plots and Egger regression, and heterogeneity was examined with a Galbraith radial plot. The protocol was registered on Prospero (CRD42021250909). Findings: A total of 73 articles from 28 countries representing 31,553 TB-treated patients were included in the narrative synthesis, with 64 of these studies included in the meta-analysis. Risk factors associated with post-TB lung sequelae include older age (OR = 1.62, 95% CI: 1.07–2.47), previous TB treatment history (OR = 3.43, 95% CI: 2.37–4.97), smoking (OR = 1.41, 95% CI: 1.09–1.83), alcohol consumption (OR = 1.84, 95% CI: 1.04–3.25), smear-positive pulmonary TB diagnosis (OR = 3.11, 95% CI: 1.77–6.44), and the presence of radiographic evidence of pulmonary lesions at the commencement of treatment (OR = 2.04, 95% CI: 1.07–3.87). Risk factors associated with post-TB liver injury included pre-existing hepatitis (OR = 2.41, 95% CI: 1.16–6.08), previous TB treatment (OR = 2.64, 95% CI: 1.22–6.67), hypo-albuminemia (OR = 2.10, 95% CI: 1.53–2.88), HIV co-infection (OR = 2.72, 95% CI: 1.66–4.46), and CD4 count

Objectives: Approximately 40% of tuberculosis (TB) cases remain undiagnosed globally. Lower lung field TB (LLF TB) presents atypically and is often misidentified as other lung diseases, leading to diagnostic delays in resource-limited settings. It may contribute to increased TB transmission and mortality. We aimed to identify microbiological determinants of LLF TB and evaluate treatment responses to optimize care. Methods: We conducted an observational cohort study in Lima, Peru, enrolling adults with microbiologically confirmed pulmonary TB (PTB) diagnosed by GeneXpert MTB/RIF assay or sputum culture. Mycobacterium tuberculosis (MTB) lineage was determined using whole-genome sequencing. Due to the delayed chest radiograph changes in LLF TB compared to non-LLF TB, we measured changes in the St. George's Respiratory Questionnaire (SGRQ) score at 2-month treatment mark and evaluated World Health Organization-specified final treatment outcomes. We used logistic regression to evaluate the associations between LLF TB and microbiological determinants and treatment outcomes. We used linear regression to assess whether the change in SGRQ scores over the first 2 months of treatment varied by LLF TB status. Results: Among 1316 PTB patients, 84 (6%) had LLF TB. Compared to non-LLF TB patients, LLF TB patients were more likely to be smear-negative (adjusted odds ratio [aOR] [95% CI] = 2.04 [1.28-3.23], P = 0.002) and to be infected with Lineage 2 (aOR [95% CI] = 1.95 [95% CI: 1.07-3.41; P = 0.024]). People with LLF TB had less improvement in SGRQ scores after 2 months of treatment (adjusted score difference [95% CI] = –6.29 [–10.99 to –1.59], P = 0.009), while they experienced better final outcomes compared to non-LLF TB patients, though this difference did not reach statistical significance (aOR = 0.43 [95% CI: 0.13-1.05], P = 0.103). Conclusion: Patients with LLF TB are more likely than those with upper lung lesions to be sputum-negative on conventional tests, to be infected with Lineage 2, and to show less clinical improvement after treatment.

Summary: Background: Tuberculosis (TB) remains a global public health challenge, causing substantial mortality and morbidity. While TB treatment has made significant progress, it often leaves survivors with post-TB sequelae, resulting in long-term health issues. Current healthcare systems and guidelines lack comprehensive strategies to address post-TB sequelae, primarily due to insufficient evidence. This systematic review and meta-analysis aimed to identify effective interventions for preventing post-TB sequelae. Methods: A systematic search was conducted across four databases including PubMed, SCOPUS, Web of Science, and Cochrane Central Register of Controlled Trials from inception to September 22, 2023. Eligible studies reported interventions designed to prevent post-TB sequelae were included. A random effect meta-analysis was conducted where applicable, and heterogeneity between studies was evaluated visually using forest plots and quantitatively using an index of heterogeneity (I2). This study is registered with PROSPERO (CRD42023464392). Findings: From the 2525 unique records screened, 25 studies involving 10,592 participants were included. Different interventions were evaluated for different outcomes. However, only a few interventions were effective in preventing post-TB sequelae. Rehabilitation programs significantly improved lung function (Hedges's g = 0.21; 95% confidence interval (CI): 0.03, 0.39) and prevented neurological sequelae (relative risk (RR) = 0.10; 95% CI: 0.02, 0.42). Comprehensive interventions and cognitive-behavioural therapy significantly reduced the risk of mental health disorders among TB survivors (Hedges's g = −1.89; 95% CI: −3.77, −0.01). In contrast, interventions targeting post-TB liver sequelae, such as vitamin A and vitamin D supplementation and hepatoprotective agents, did not show significant reductions in sequelae (RR = 0.90; 95% CI: 0.52, 1.57). Moreover, adjunctive therapies did not show a significant effect in preventing post-TB neurological sequelae (RR = 0.62, 95% CI: 0.31, 1.24). Interpretation: Rehabilitation programs prevented post-TB lung, neurologic and mental health sequelae, while adjuvant therapies and other interventions require further investigation.

Summary: Mammalian cells can die by apoptosis or by one of several non-apoptotic mechanisms, such as ferroptosis. Here, we present a protocol to distinguish ferroptosis from other cell death mechanisms in cultured cells. We describe steps for seeding cells, administering mechanism-specific cell death inducers and inhibitors, and measuring cell death and viability. We then detail the use of molecular markers to verify mechanisms of cell death. This protocol can be used to identify and distinguish ferroptosis in 2D and 3D cultures.For complete details on the use and execution of this protocol, please refer to Ko, et al. (2019),1 Magtanong, et al. (2022),2 and Armenta, et al. (2022).3 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.

Background: MP-AzeFlu (Dymista®; spray of azelastine/fluticasone propionate) is the most effective allergic rhinitis (AR) treatment available. Its effect on asthma outcomes in patients with AR and asthma is unknown. Methods: This pre-post historical cohort study, using the Optimum Patient Care Research Database, included patients aged ≥12 years, from UK general practice with active asthma (defined as a recorded diagnosis, with ≥1 prescription for reliever or controller inhaler) in the year before or at the initiation date. The primary study outcome was change in number of acute respiratory events (i.e. exacerbation or antibiotic course for a respiratory event) between baseline and outcome years. The effect size of MP-AzeFlu was quantified as the difference in % of patients that improved and worsened. Results: Of the 1,188 patients with AR and asthma included, many had a record of irreversible obstruction (67%), and uncontrolled asthma (70.4%), despite high mean daily doses of reliever/controller therapy and acute oral corticosteroid use, in the year pre-MP-AzeFlu initiation. MP-AzeFlu initiation was associated with fewer acute respiratory events (effect size (e) = 5.8%, p = 0.0129) and a reduction in daily use of short-acting β2-agonists, with fewer patients requiring >2 SABA puffs/week (e = 7.7% p

The targeted disruption of the low density lipoprotein (LDL) receptor gene in mice results in accumulation of plasma LDL cholesterol and in predisposition to diet-induced aortic atherosclerosis. Although the liver is the central organ for receptor mediated clearance of LDL, the in vivo role of other organs and tissues in LDL catabolism has not been directly studied. Since bone marrow-derived cells such as blood leukocytes and tissue macrophages express LDL receptors and contribute a large mass to the body, we designed bone marrow transplantation (BMT) experiments to reconstitute LDL receptor null mice [LDL-R(-/-)] with marrow obtained from LDL-R wild-type mice [LDL-R(+/+)] and evaluate the effects on parameters of plasma lipid metabolism. Although reconstitution of the transplanted mice with donor bone marrow cells was complete, no differences in plasma lipid levels and lipoprotein distribution were found between groups, irrespective of the diet used, and turnover studies using 125I-labeled LDL showed that LDL receptor expression by leukocytes and macrophages does not significantly contribute to plasma LDL clearance. The complementary experiment of transplanting LDL-R(-/-) marrow into C57BL/6 recipients [LDL-R(-/-)–>LDL(+/+)], performed to evaluate the role of leukocyte LDL-R in normocholesterolemic condition, also produced no effects on plasma lipid parameters. LDL binding studies using macrophages isolated from transplanted mice showed a lack of LDL-R expression. Thus, despite their large number and wide distribution, bone marrow-derived cells do not significantly influence receptor-mediated clearance of plasma LDL.

Adolescents are particularly vulnerable to health misinformation and are at risk for suboptimal adherence to protective health behaviors in the COVID-19 pandemic. Guided by factors consistent with the theories of planned behavior and rumor transmission, this study sought to analyze the impact of multiple information sources, including social media, television media, internet and parental counseling, on masking behaviors in adolescents. Responses from the December 2020 COVID-19 survey, representing 4,106 U.S. adolescents ages 12–14 from the Adolescent Brain Cognitive Development Study (ABCD) were analyzed. The majority of parents (61.1%) reported counseling their children on the importance of wearing masks all the time in the past week. A minority of adolescents reported more than one hour of daily exposure to COVID-19 related information on social media (9.1%), the internet (4.3%) and television (10.2%). In unadjusted and adjusted models, greater frequency of parental counseling and exposure to COVID-19 television or social media were associated with 'always masking' behaviors. Our findings provide support for the importance of parent counseling and suggest that social media and television may overall support rather than dissuade protective COVID-19 health behaviors in adolescents.

Malaria, HIV, and tuberculosis (TB) collectively account for several million deaths each year, with all three ranking among the top ten killers in low-income countries. Despite being caused by very different organisms, malaria, HIV, and TB present a suite of challenges for mathematical modellers that are particularly pronounced in these infections, but represent general problems in infectious disease modelling, and highlight many of the challenges described throughout this issue. Here, we describe some of the unifying challenges that arise in modelling malaria, HIV, and TB, including variation in dynamics within the host, diversity in the pathogen, and heterogeneity in human contact networks and behaviour. Through the lens of these three pathogens, we provide specific examples of the other challenges in this issue and discuss their implications for informing public health efforts.

Background: Between April and June, 2012, a reactive cholera vaccination campaign was done in Haiti with an oral inactivated bivalent whole-cell vaccine. We aimed to assess the effectiveness of the vaccine in a case-control study and to assess the likelihood of bias in that study in a bias-indicator study. Methods: Residents of Bocozel or Grand Saline who were eligible for the vaccination campaign (ie, age ≥12 months, not pregnant, and living in the region at the time of the vaccine campaign) were included. In the primary case-control study, cases had acute watery diarrhoea, sought treatment at one of three participating cholera treatment units, and had a stool sample positive for cholera by culture. For each case, four control individuals who did not seek treatment for acute watery diarrhoea were matched by location of residence, enrolment time (within 2 weeks of the case), and age (1–4 years, 5–15 years, and >15 years). Cases in the bias-indicator study were individuals with acute watery diarrhoea with a negative stool sample for cholera. Controls were selected in the same manner as in the primary case-control study. Trained staff used standard laboratory procedures to do rapid tests and stool cultures from study cases. Participants were interviewed to collect data on sociodemographic characteristics, risk factors for cholera, and self-reported vaccination. Data were analysed by conditional logistic regression, adjusting for matching factors. Findings: From Oct 24, 2012, to March 9, 2014, 114 eligible individuals presented with acute watery diarrhoea and were enrolled, 25 of whom were subsequently excluded. 47 participants were analysed as cases in the vaccine effectiveness case-control study and 42 as cases in the bias-indicator study. 33 (70%) of 47 cholera cases self-reported vaccination versus 167 (89%) of 188 controls (vaccine effectiveness 63%, 95% CI 8–85). 27 (57%) of 47 cases had certified vaccination versus 147 (78%) of 188 controls (vaccine effectiveness 58%, 13–80). Neither self-reported nor verified vaccination was significantly associated with non-cholera diarrhoea (vaccine effectiveness 18%, 95% CI −208 to 78 by self-report and −21%, −238 to 57 by verified vaccination). Interpretation: Bivalent whole-cell oral cholera vaccine effectively protected against cholera in Haiti from 4 months to 24 months after vaccination. Vaccination is an important component of efforts to control cholera epidemics.

Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC) increases the risk of heart failure (HF) and arrhythmias. While speckle tracking echocardiography (STE) detects myocardial dysfunction, its predictive role for HF in this population remains unclear., Methods: 71 patients with ARVC (43.7±14.8 years, 53.5% male) without prevalent HF at baseline enrolled in the Johns Hopkins ARVC registry were retrospectively included. Global strain (GS) and strain rate (SR) of the left ventricle (LV), right ventricle free-wall (RVFW), left atrium (LA), and right atrium (RA) were measured by a blinded operator. Cox regression models assessed their association with incident HF., Results: Incident HF developed in 23 patients (49.3±12.5 years, 52.2% male) during a median follow-up of 2.7 years. Decreases in strain were significantly associated with HF: LVGLS (HR: 1.20, 95% CI: 1.06-1.35, P=0.003), RVFWS (HR: 1.11, 95% CI: 1.04-1.18, P=0.003), LAGS (HR: 1.05, 95% CI: 1.00-1.09, P=0.030) and RAGS (HR: 1.07, 95% CI: 1.03-1.12, P<0.001). Associations for LVGLS, RVFWS and RAGS remained significant after adjusting for age and sex. Strain values frequently fell below established reference ranges. Any strain value (LVGLS, RVFWS, LAGS, or RAGS) below the normal limit was associated with an eightfold increase in HF (HR 8.43, 95% CI 1.97-36.02, P=0.004), while each individual component below the normal threshold doubled the risk (HR 2.35, 95% CI 1.60-3.45, P<0.001)., Conclusions: STE deformation abnormalities are associated with incident HF in ARVC patients. Echocardiographic strain may aid in identifying patients at risk of HF for closer follow-up and management., (Copyright © 2024. Published by Elsevier Inc.)

Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare genetic heart disease associated with life-threatening ventricular arrhythmias. Diagnosis of ARVC is based on the 2010 Task Force Criteria (TFC), application of which often requires clinical expertise at specialized centers., Objective: The purpose of this study was to develop and validate an electrocardiogram (ECG) deep learning (DL) tool for ARVC diagnosis., Methods: ECGs of patients referred for ARVC evaluation were used to develop (n = 551 [80.1%]) and test (n = 137 [19.9%]) an ECG-DL model for prediction of TFC-defined ARVC diagnosis. The ARVC ECG-DL model was externally validated in a cohort of patients with pathogenic or likely pathogenic (P/LP) ARVC gene variants identified through the Geisinger MyCode Community Health Initiative (N = 167)., Results: Of 688 patients evaluated at Johns Hopkins Hospital (JHH) (57.3% male, mean age 40.2 years), 329 (47.8%) were diagnosed with ARVC. Although ARVC diagnosis made by referring cardiologist ECG interpretation was unreliable (c-statistic 0.53; confidence interval [CI] 0.52-0.53), ECG-DL discrimination in the hold-out testing cohort was excellent (0.87; 0.86-0.89) and compared favorably to that of ECG interpretation by an ARVC expert (0.85; 0.84-0.86). In the Geisinger cohort, prevalence of ARVC was lower (n = 17 [10.2%]), but ECG-DL-based identification of ARVC phenotype remained reliable (0.80; 0.77-0.83). Discrimination was further increased when ECG-DL predictions were combined with non-ECG-derived TFC in the JHH testing (c-statistic 0.940; 95% CI 0.933-0.948) and Geisinger validation (0.897; 95% CI 0.883-0.912) cohorts., Conclusion: ECG-DL augments diagnosis of ARVC to the level of an ARVC expert and can differentiate true ARVC diagnosis from phenotype-mimics and at-risk family members/genotype-positive individuals., Competing Interests: Disclosures Dr Calkins is a consultant for Medtronic Inc., Biosense Webster, Pfizer, StrideBio, Abbott, and Tenaya; and receives research support from Boston Scientific.

Traditional cardiomyopathy paradigms segregate inflammatory etiologies from those caused by genetic variants. An identified or presumed trigger is implicated in acute myocarditis or chronic inflammatory cardiomyopathy but growing evidence suggests a significant proportion of patients have an underlying cardiomyopathy-associated genetic variant often even when a clear inflammatory trigger is identified. Recognizing a possible genetic contribution to inflammatory cardiomyopathy may have major downstream implications for both the patient and family. The presenting features of myocarditis (i.e. chest pain, arrhythmia, and/or heart failure) may provide insight into diagnostic considerations. One example is isolated cardiac sarcoidosis, a distinct inflammatory cardiomyopathy that carries diagnostic challenges and clinical overlap; genetic testing has increasingly reclassified cases of isolated cardiac sarcoidosis as genetic cardiomyopathy, notably altering management. On the other side, inflammatory presentations of genetic cardiomyopathies are likewise underappreciated and a growing area of investigation. Inflammation plays an important role in the pathogenesis of several familial cardiomyopathies, especially arrhythmogenic phenotypes. Given these clinical scenarios, and the implications on clinical decision making such as initiation of immunosuppression, sudden cardiac death prevention, and family screening, it is important to recognize when genetics may be playing a role., (Copyright © 2024 Elsevier Ireland Ltd.

Miniaturized chromatography columns (minicolumns) operated by automated liquid handlers are an integral part of bioprocess purification development. However, these systems can be limited in both their efficiency and accessibility. Because the minicolumn chromatography operation itself is higher throughput, the lower throughput pre- and post-operation activities become the bottleneck of the workflow. Additionally, method writing and operation of the systems while varying multiple parameters, using a design of experiments approach for example, can be error-prone and resource intensive. Here, we have developed a fully automated minicolumn chromatography system to both address these bottlenecks and improve the accessibility of these systems by allowing users to enter chromatography-relevant information through a simplified user interface. Methods have been developed to automate buffer preparation and protein solution titration leveraging modeling and integrated pH probes with feedback control. Chromatogram generation and fraction pooling has additionally been automated to improve the efficiency of post-chromatography operations. We have also demonstrated the flexibility of the system through an example run where both bind-and-elute chromatography and flowthrough chromatography experiments were performed in parallel. Additionally, all methodology and parameters to operate the system have been shared. We hope this will help interested parties improve the efficiency and accessibility of their minicolumn chromatography systems., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Background: The diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC) is challenging because of nonspecific clinical findings and lack of conclusive answers from genetic testing (ie, an ARVC-related variant is neither necessary nor sufficient for diagnosis). Despite the revised 2010 Task Force Criteria, patients are still misdiagnosed with ARVC., Objective: In patients referred for ARVC, we sought to identify the clinical characteristics and diagnostic confounders for those patients in whom ARVC was ultimately ruled out., Methods: Patients who were referred to our center with previously diagnosed or suspected ARVC (between January 2011 and September 2019; N = 726) were included in this analysis., Results: Among 726 patients, ARVC was ruled out in 365 (50.3%). The most common presenting symptoms in ruled-out patients were palpitations (n = 139, 38.1%), ventricular arrhythmias (n = 62, 17.0%), and chest pain (n = 53, 14.5%). On the basis of outside evaluation, 23.8% of these patients had received implantable cardioverter-defibrillators (ICDs) and device extraction was recommended in 9.0% after reevaluation. An additional 5.5% had received ICD recommendations, all of which were reversed on reevaluation. The most frequent final diagnoses were idiopathic premature ventricular contractions/ventricular tachycardia/ventricular fibrillation (46.6%), absence of disease (19.2%), and noncardiac presyncope/syncope (17.5%). The most common contributor to diagnostic error was cardiac magnetic resonance imaging, including mistaken right ventricular wall motion abnormalities (33.2%) and nonspecific fat (12.1%)., Conclusion: False suspicion or misdiagnosis was found in the majority of patients referred for ARVC, resulting in inappropriate ICD implantation or recommendation in 14.5% of these patients. Misdiagnosis or false suspicion was most commonly due to misinterpretation of cardiac magnetic resonance imaging., (Copyright © 2023 Heart Rhythm Society. Published by Elsevier Inc.

Background: Orbital cellulitis is an infrequent but serious infectious complication of rhinosinusitis, most commonly seen in the pediatric population. Extension into the cavernous sinus, leading to further infection and thrombosis, is a rare but life-threatening complication. Although COVID-19 has been linked to an increased risk of venous thromboembolism, most cases involve extremity deep venous thrombosis or pulmonary embolism; reports of intracranial or jugular system thrombosis are rare., Case Report: We describe a case of a 17-year-old female patient with no significant medical history or thrombotic risk factors found to have orbital cellulitis and severe pansinusitis, complicated by multiple venous thromboses in the head and neck requiring emergent surgical intervention and pediatric intensive care admission. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Extensive head and neck venous thrombosis and intracranial abscesses are rare complications of pansinusitis and orbital cellulitis, and the thrombotic complications of COVID-19 are well documented. A delay in diagnosis and treatment can lead to potentially devastating consequences., (Published by Elsevier Inc.)

Objectives: Alzheimer's disease and related dementias (ADRD) are prevalent conditions in long-term care homes (LTCHs) with most LTCH residents living with ADRD in many countries. Despite the prevalence of ADRD in LTCHs, a recent examination of LTCH quality measurement programs in 4 countries revealed few LTCH quality measures addressed ADRD, most commonly as a risk adjuster. We sought to better understand how quality measurement programs address ADRD internationally., Design: International comparative analysis., Setting and Participants: We examined LTCH quality measures in 4 European countries-Germany, Switzerland, Belgium, and the Netherlands., Methods: The specifications to calculate each measure were assessed to determine whether the measure was calculated without assessing for ADRD, included only residents with ADRD, excluded residents with ADRD, or was risk adjusted for the presence of ADRD among the LTCH residents., Results: A total of 143 measures were examined across 4 quality measurement programs. Thirty-seven percent of the measures explicitly address ADRD. The programs addressed ADRD in starkly different ways. In Germany, most (13 of 15) measures addressed ADRD, and did so as an exclusion or inclusion criterion, and in Switzerland all the measures addressed ADRD through risk adjustment. In Flanders, Belgium, all measures were calculated without assessing for ADRD. In the Netherlands, one-third of the measures explicitly addressed ADRD by restricting the measure to psychogeriatric units., Conclusions and Implications: Although limited to examining measures from LTCH quality measurement programs in 4 European countries, this study adds evidence that ADRD tends not to be addressed by LTCH quality measures, but when ADRD is addressed, it tends to be through inclusion or exclusion criteria. LTCH regulators, policymakers, and providers can use this information to assess options for addressing ADRD in quality measurement programs. Future research is needed to assess how standard indicators of ADRD care quality differ across quality measurement programs., (Copyright © 2023 AMDA – The Society for Post-Acute and Long-Term Care Medicine.
